Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water reversal molding method for a wash basin or the like, and more particularly, to a counter portion when molding a wash basin or a sink by casting a molding material such as imitation marble into a mold. The present invention relates to a method capable of simultaneously forming a water repellent located at the boundary between a sink and a sink part when molding the wash basin or the like.

2. Description of the Related Art For example, in a wash basin in which a molding material is poured into a mold for molding, a counter unit 16 and a sink unit 22 are integrated as shown in FIG. Many types are known, including different types. As the material of the wash basin 10 of this type, stainless steel plates, hard pottery and other enamels have been conventionally used, but in recent years, as typified by artificial marble, molding obtained by kneading the required powder with water or the like. A wash basin, which is formed by pouring a material into a required mold and hardening it, has come into widespread use.

In this type of washbasin, as shown in FIG. 8, a so-called water return section 11 is formed on the front side of the washbasin, and a sink section 22 is formed.
Measures to prevent water splashing are generally taken. As a method for molding the water return portion 11, for example, FIG.
As shown in FIG. 3, a mold 13 for molding the water return portion 11 is formed.
Is attached to the convex portion 12a of the counter mold 12 formed into a required cross-sectional shape. That is, the mold 13 is detachably fitted at one end thereof to the notch 12c having a rectangular cross section provided in the convex portion 12a, and the counter mold 1
It is constructed integrally with 2. In this case, the mold 13 has the other end portion formed in an arcuate cross section with respect to the one end portion.
It is adapted to slightly project from the peripheral end of the convex portion 12a.

A sink mold 20 is adhered to the counter mold 12 from above, and a molding material 14 is poured into a bowl-shaped hollow portion 17 formed between the two molds. Then, after the molding material 14 is cured, the counter mold 12 and the sink mold 20
The counter unit 1
The washbasin 10 in which 6 and the sink portion 22 are integrated is molded. At this time, the counter mold 12 is detached from the mold 13 in a separated state. Therefore, as shown in FIG. 8B, the mold 1 is placed on the back side of the wash basin 10 (in the direction indicated by the arrow).
The water return portion 11 is formed by removing 3.

Further, as shown in FIG. 9, the counter unit 16
There is known a so-called under-counter type washbasin in which the sink portion 22 and the sink portion 22 are separately molded, and the sink portion 22 is attached to the lower surface of the counter portion 16 afterwards. In the case of the wash basin 10, the plate body serving as the counter portion 16 is formed in a state where the hole 16a having, for example, an elliptical shape or an elliptical shape is provided at a required portion thereof. The upper surface portion of the sink portion 22 is set to have a size slightly wider than the inner diameter of the hole 16a. Therefore, the water return portion 11 is formed by attaching the upper surface of the sink portion 22 to the lower surface of the counter portion 16 via the metal fittings 15, 15 which are previously arranged in the counter portion 16.

[0006]

As described above, in the method of forming the water return part on the wash basin or the like, in the case where the counter part 16 and the sink part 22 are integrally formed, the water return part 11 is used.
The mold 13 for molding is fixed from the lower surface of the counter mold 12 with bolts (not shown) or the like. Further, in order to prevent the molding material 14 from entering the slight gap between the mold 13 and the counter mold 12 to form a “burr”, the joint between the mold 13 and the counter mold 12 is stopped. It is designed to be stopped by a drug. This eliminates the work of removing the "burrs", but on the other hand, it takes time and effort to apply the sealing agent each time the wash basin or the like is molded. For this reason, on the contrary, it takes a long time to attach and detach the mold 13 and the counter mold 12, which causes a problem that work efficiency is significantly reduced.

Further, in the under-counter type wash basin, as described above, when the sink portion 22 and the counter portion 16 are joined together, the mounting metal fitting 1 previously arranged in the counter portion 16 is provided.
The sink portion 22 is fixed via the terminals 5 and 15. At this time, it is necessary to attach a waterproof seal to the joint portion between the sink portion 22 and the counter portion 16 and separately perform the work of providing watertightness. For this reason, there are disadvantages that a complicated work is required for mounting and a large number of mounting parts are required, which inevitably increases the manufacturing cost.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a water reversal molding method for a wash basin and the like according to the present invention will be described below with reference to the accompanying drawings with reference to preferred embodiments. It should be noted that the same reference numerals are used for the same or similar members that have already been mentioned.

In this water reversal molding method, as shown in FIG. 1, a counter mold 12 having a convex portion 12a forming a sink portion 22 at a substantially central portion is placed in a reversal posture with the convex portion 12a oriented upward. Place it horizontally with this counter type 1
From above 2, the water flip mold 18 is adhered to the convex portion 12a.

The water reversing mold 18 is formed by recessing a sheet having a required thickness made of an elastic material such as rubber or silicon, and the entire convex portion 12a of the counter mold 12 is closely adhered from its upper portion. The size is set to cover. Further, as shown in FIG. 2, the molding die 18 has a height whose open end is located at an expected boundary portion between the counter portion 16 and the sink portion 22 when it is attached to the convex portion 12a. Is dimensioned. A gel coat made of polyester resin is spray-coated and cured on the entire surface of the counter mold 12 covered with the mold 18.

From the upper side of the water reversing mold 18, as shown in FIG.
As shown in FIG. 5, the sink mold 20 that covers the entire counter mold 12 is put upside down. As a result, a hollow portion 17 forming a required gap is defined between the sink mold 20 and the water return mold 18 and the counter mold 12. As shown in FIG. 3, a molding material 14 such as imitation marble is poured into the hollow portion 17 through a hole 20a formed at the top of the sink mold 20. 14, the counter unit 16 and the sink unit 2
2 is molded at once. It is empirically known that the molding material 14 itself used for this molding rises to a certain temperature (about 40 to 50 degrees) due to a required chemical change when it is mixed or poured into a mold. Has been. Therefore, the molding die 18 is preferably used even if it is a material other than the above-mentioned rubber and the like, as long as it is an elastic material whose melting point is equal to or higher than the above temperature. Further, a vinyl chloride pipe (not shown) for overflow is set in advance on the surface of the molding die 18 between the molding die 18 and the sink die 20.

After the molding member 14 is completely cured by natural drying or the like, the counter mold 12 and the sink mold 20 are released from the mold, as shown in FIG. As a result, the washbasin 10 in which the counter portion 16 and the sink portion 22 are integrated is obtained. At this time, since the open end of the water reversing mold 18 is engaged with the protruding portion of the hole 16a formed in the counter portion 16, it remains in close contact with the inner surface of the sink portion 22. There is. However, as described above, since the water flip mold 18 is made of an elastic member such as rubber, the open end can be easily detached from the sink part 22 by manually separating the open end from the engaging end with the hole 16a. be able to. As a result, as shown in FIG. 5, the counter unit 16 and the sink unit 22 are
The wash basin 10 in which the water repelling part 11 is formed at the boundary part between and is obtained.

Next, the molding of the water return portion 11 by another molding method for the washbasin 10 will be described. This molding method is carried out for the purpose of integrally molding the counter portion 16 and the sink portion 22 each having different colors, and the above-mentioned counter mold 12 is placed from above the counter die 12 which is horizontally placed in the inverted posture. The water repelling mold 18 is attached to the convex portion 12a in close contact. The open end of the water reversing mold 18 is
It is located at the expected boundary between the counter section 16 and the sync section 22. Then, as shown in FIG. 6, the molding material 14 is poured into the horizontal portion 12 b of the counter mold 12. Thereby, the counter unit 1 surrounding the base of the convex portion 12a
6 is preformed.

After waiting for a required time until the molding material 14 poured into the counter mold 12 is in a semi-cured state, the counter portion 16 is at least partially covered from above the water reversing mold 18 as shown in FIG. The sink die 20 is covered so that a hollow portion 17 having a required gap is defined between the molding die 18 and the sink die 20. This hollow part 1
By pouring the molding material 14 of the same kind as the molding material 14 poured into the counter mold 12 but having a different color, the counter portion 16 and the sink portion 22 having a different color are molded. The counter portion 16 when the molding die 18 and the sink die 20 are attached is in a semi-cured state as described above. Therefore, the sink portion 22 formed of another molding material 14 poured later is completely integrated at the boundary with the counter portion 16. Further, the molding material 14 forming the sink portion 22 is the counter portion 1
6 does not mix with the molding material 14 from which it is formed.

In this state, the molding member 14 forming the counter portion 16 and the sink portion 22 is completely cured by natural drying or the like, and then, as described with reference to FIG.
Then, the sink type 20 is released from the mold. Also sink type 2
The water reversal molding die 18 remaining on the inner surface of 0 is detached from the sink portion 22. As a result, the washbasin 10 in which the counter section 16 and the sink section 22 are clearly color-coded
Is molded, the counter section 16 and the sink section 22 are formed.
The water repelling part 11 formed at the boundary part between and is obtained. In this embodiment, molding of the washbasin is described, but as long as it is basically composed of the counter section and the sink section, it can be applied as it is to molding of a sink or a bathtub of a kitchen or the like.

[0019]

As described above, in the water reversal molding method for a wash basin and the like according to the present invention, since the counter portion and the sink portion are integrally molded, no member such as a fitting is required. Further, in forming the water repelling portion, it suffices to attach the water repelling mold to the counter mold in close contact. For this reason, it is possible to surely form the water return portion at the boundary portion between the counter portion and the sink portion, although the attaching / detaching of the forming die is extremely easy. Further, the water reversing mold itself has the advantage that the manufacturing cost of the washbasin can be reduced because it can be repeatedly used.
