Abstract

(57) [Abstract] [Purpose] To provide a washbasin having a shape that allows an upper mold to be easily removed from a base material in a molding process. [Structure] Of the inner and outer double projections 3 and 4 provided on the upper edge surface 2 of the washbasin, the top 3a of the outer projection 3 is the upper edge surface 2
It is formed so as to be located on the outer edge of. [Effect] In the molding step, the outer convex strips 3 of the washbasin substrate 1 do not go inward from the position of the dividing surface 11 between the upper mold 10 and the lower mold 20. Therefore, the air 7 blown when the upper mold 10 is demolded from the washbasin substrate 1 can be easily introduced into the boundary surface between the two, so that the upper mold can be easily demolded and the manufacturing efficiency is improved. To do.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a so-called undercounter type basin which is attached to the lower surface of a counter with its upper edge surface in contact, and more specifically, to remove the upper mold from a molded basin body. The purpose is to provide a shape that is easy to use.

[0002]

[Prior Art]

FIG. 3 shows a so-called under-counter type basin 30 which is attached to the lower surface 61 of the counter 60 with the upper edge surface 35 in contact therewith. The upper edge surface 35 of the undercounter type basin 30 is usually provided with inner and outer double ridges 36 and 37 as shown in an enlarged scale in FIG. , 37 is filled with the sealing material 40 to ensure close contact with the counter lower surface 61.

[0004]

[Problems to be solved by the device]

 By the way, the conventional under-counter type wash basin 30 has the above-mentioned upper edge surface structure, and therefore has the following problems in molding. To form a washbasin, first, as shown in FIG. 5, an upper mold 31 forming the upper surface of the washbasin and a lower mold 32 forming the lower surface of the washbasin are combined to form a casting space inside. Once provided, the slurry is then poured and allowed to infiltrate to obtain the washbasin substrate 34 as shown. Subsequently, as shown in FIG. 6, the washbasin substrate 34 is held in close contact with the upper mold 31 and the lower mold 32 is removed.

Subsequently, the upper mold 31 is demolded from the washbasin substrate 34. At this time, as shown in the enlarged view of FIG. 7, air 50 is blown between the washbasin substrate 34 and the upper mold 31, It is common practice to separate the two. However, in the conventional washbasin, the inner and outer double ridges 36 and 37 are provided on the upper edge surface 35 as described above, and the ridges 36 and 37 are located inside the dividing surface 33 of the upper die 31. Have fallen into. This is because the protrusions 36 and 37 are formed on the upper edge surface 35, and in order to enable the mold release of the lower mold 32, the position of the dividing surface 33 between the upper mold 31 and the lower mold 32 is set to the above-mentioned position. This is because it is necessary to set the ridges 36 and 37 below the base ends (on the left side in FIG. 7).

As described above, in order to form the conventional washbasin 30, since the ridges 36 and 37 of the upper edge surface 35 of the washbasin base 34 are recessed into the upper mold 31, the air is removed from the air. Even if 50 was blown, it was difficult for this to enter the boundary surface between the washbasin base 34 and the upper mold 31, and it was not easy to separate the two.

[0007]

[Means for Solving the Problems]

 The present invention is an under-counter type washbasin that was devised to solve the above-mentioned conventional problems, and is characterized in that a groove is formed between the upper edge surface of the washbasin to form a double-sided interior A ridge is provided and the top of the outer ridge is located on the outer edge of the upper edge surface.

[0008]

[Action]

 In the washbasin according to the present invention, among the inner and outer double ridges provided on the upper edge surface, the outer ridge is formed so that the top thereof is located at the outer edge of the upper edge surface. The ridges on the outside of the surface of the surface of the surface of the surface of the surface of the surface of the surface of the base material do not intrude inward from the position of the dividing surface between the upper mold and the lower mold. Therefore, the air blown when removing the upper mold from the washbasin substrate can easily enter the boundary surface between the two.

In the washbasin according to the present invention, it is difficult to provide a curved surface on the outer edge of the upper edge surface as in the conventional case, but this does not cause any problem. This is because when the washbasin is used as an undercounter type, even if the outer edge of the upper edge surface is angular, it does not completely impair the appearance and safety in the state after construction. Because there is no.

[0010]

【Example】

 Hereinafter, the details of the present invention will be described with reference to the drawings illustrating an embodiment. FIG. 1 shows a process of forming a washbasin according to the present invention. In molding the washbasin substrate 1, the upper mold 10 forming the upper surface side of the washbasin and the lower mold 20 forming the lower surface side of the washbasin are combined to inject the slurry into the casting space formed inside, Inking this is the same as in the past.

The feature of the washbasin 1 according to the present invention is that, as shown in an enlarged view of the main part in FIG. 2, the inner and outer double ridges 3 and 4 provided on the upper edge surface 2 with the groove portion 5 therebetween. Of these, the top 3a of the outer ridge 3 is located at the outer edge of the upper edge surface 2. In this embodiment, the inner and outer ridges 3 and 4 and the groove 5 are formed in a continuous curved surface, and the top 3a of the outer ridge 3 is set so as to intersect the outer surface 6 of the washbasin substrate 1. .. By providing the shape of the upper edge surface 2 as described above, when the upper mold 2 is released from the washbasin substrate 1, the blown air 7 can easily enter the boundary surface between the upper mold 2 and the upper mold 2. Separation becomes easy.

However, in the washbasin 1 according to the present invention, as can be seen from the drawings, it is difficult to form the intersection of the upper edge surface 2 and the outer surface 6 into a curved surface, and as a result, it becomes angular. become. However, since the washbasin 1 of the present invention is attached to the lower surface of the counter, in the state after construction, even if the intersection 3a between the upper edge surface 2 and the outer surface 6 is angular, the appearance is It does not cause any problems regarding sex and safety.

In addition, the embodiment of the present invention does not prevent appropriate changes depending on the situation, and various applications are possible.

[0014]

[Effect of the device]

 As is apparent from the above description, in the washbasin according to the present invention, the outer ridge of the inner and outer double ridges provided on the upper edge surface is located at the top of the outer edge of the upper edge surface. The air blown when the upper mold is removed from the washbasin substrate can easily enter the boundary between the two in the molding process, which facilitates the separation of the upper mold. Becomes As a result, the manufacturing efficiency of the washbasin is improved.
