Abstract

PURPOSE:To inhibit the leakage of water while facilitating the work of attaching a drain pipe, by forming the main part of said drain pipe to be attached to a drain opening for the parts of a bathtub and a wash place as a unitary body with a bathroom unit. CONSTITUTION:The surface of a male die 11 for forming the half unit 4 of a bathroom comprising a bathtub part 1 and a wash place part 2 is covered with a preform 12 for forming a unit. A T-shaped inserting solid member 14 is vertically provided at a dent part 13 for forming the lower cavity 5 of the half unit 4 of the bathroom, its horizontal part 14' is suspensibly extended along a horizontal direction so as to cover the parts 15, 16 at which drain openings 8, 9 are to be formed, and the outer surface of said horizontal part 14' is covered with another preform 17 for forming a draining cavity. Thereafter, a female die 18 is inserted onto the male die 11, and synthetic resin is poured into a separate cavity formed between the dies and then cured. After the molded body is taken out of the dies, drain openings 8, 9 and an outflow opening 20 are provided in it, and the inserting solid member 14 is scraped out. Thus, the half unit 4 of the bathrrom is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for molding a bathroom half unit in which a bathtub part (1) and a washing part (2) are integrally molded. ) and the upper connection part (
3) A synthetic resin bathroom half unit (4) is used, and the product is manufactured using a molding method such as a press method or a resin injection method.

By the way, since the half unit (4) has a lower space (5) formed between the bathtub part (1) and the washing water part (2) as shown in the figure, both of these parts fil F21 k I
J-bu (6) [To connect with the trowel (after setting the steady rest state, the mount (7) consisting of pillars etc. formed integrally with the above-mentioned ribs (6) etc. (this unit (4) k-mounted) After fixing in place, drain the bathtub part fil and washing water part (2) +
I am planning to install all drain pipes at 81 and 91 respectively.

However, in the case of such a configuration, it is necessary to perform installation work in a narrow space (drainage pipe QO above the trowel) inside the pedestal (7), which only makes the work difficult and increases the risk of water leakage. There was one drawback that caused problems.

Therefore, in view of the above-mentioned conventional difficulties, the present invention provides a structure in which the main part of the drain pipe that can be accessed to the drain outlet of the bathtub part and the washing area part can be integrally molded with the bathroom half unit. The purpose is to provide a method for molding the same unit that overcomes the deficiencies of the prior art.

゛Hereinafter, the molding method according to the present invention will be described in detail based on the illustrated embodiment. In the drawings, the same members are indicated by the same symbols as in FIG. 1 according to the conventional example. +4+ Male mold 11 prepared for k molding
The surface of 11 is coated with glass fibers as shown in FIGS. 2 and 3 of the known unit-forming preform α.

After that, the preform U (in other words, the lower cavity (5) of the bathroom half unit (4), the recess 03 to be completely formed)
), a substantially T-shaped inserting solid material made of urethane or the like is placed on a part or all of it (as shown in Figure 4), and the said inserting solid material is Horizontal part ψ of chestnut (b)
Φ′ is the drain port [81+9
1 is to be formed (us ai3) is covered (this is extended horizontally).

Furthermore, the above-mentioned fitted solid material (horizontal part H'l of 14J is the preform punch for forming a drainage cavity, and its peripheral part qη' is Ai
The unit forming preform (covered so as to extend up to 121).

After the preparation process as described above is completed, the female mold α8) is covered as shown in Fig. 4, and the female mold α8) is completely covered with a predetermined gap formed between the two mold circles α8). As is known, the product is obtained by fixing it with an appropriate means (not shown) and press-fitting the synthetic resin through the resin injection port of the resin injection method (in case of failure, the female mold 08 (not shown)). In the manufactured product, the above-mentioned solid material rs is embedded in a synthetic resin resin 911 and integrated.

Finally, the entire process is completed by demolding the female mold Q8 as is known.

Therefore, the bathroom half unit +41 molded as above
Use the bathtub (1) as shown in Figure 5.
At the same time, open the drainage ports +81 +9+ of the washing area (2), and open the drainage outlet (20) in the drainage cavity forming preform encapsulated with synthetic resin. The solid material inserted in the preform (1?
The solid fitting material 041 that has been fixed for five days remains.

Furthermore, a drain tube (c) (c) with a perforated plate is attached to the drain port +81191, but the bathtub part (1
) side only has a perforated plate (2) and no drain pipe (c) is required.

After installing the drain outlet (20) and the drain pipe (4) in the preform Q71 for forming a drainage cavity, the unit (4) is placed on a stand (not shown). As such, the method of the present invention connects the bathtub part (1) and the washing area part (2) into an integral body through the upper connecting part (3), and connects the lower connecting part (1) and the washing area part (21). In a method of mechanically molding a bathroom half unit (4) in which a cavity (5) is formed using a synthetic resin that fills a gap between a male mold circle and a female mold (18), After covering the surface of the unit forming preform 021, the preform (+21 above) is placed in the recess (13) where the lower cavity (5) of the bathroom half unit (4) is to be formed.
When a part or all of the T-shaped fitting solid material is placed vertically, the horizontal part of the fitting solid material is a bathroom) H-T unit (4) Drain ports provided on the bottom walls of the bathtub section (1) and washing area section (2) +81 +
The horizontal part 541' of the above-mentioned fitted solid plate is extended horizontally so as to cover the 1st place where 9+ is to be formed.
C beam 1 is covered with a water cavity forming preform (17),
11J Synthetic resin (1!l) filled in the gap between the male mold circle and the female mold (18) +Therefore, the above-mentioned solid material is completely covered and is characterized by being wrapped. Therefore, according to the method of the invention, the bathroom nof unit (a)
Since a part of the drain pipe that can be removed and leaked can be molded integrally with the unit (4), it is possible to greatly improve the workability of the unit (4) in terms of the number of drain pipes. (child,
It is possible to eliminate the risk of water leakage, and the bathtub part (1) and washing area part (2) of the bathroom notebook unit (4) are made of the above-mentioned solid material and preform for forming a drainage cavity. Since they are connected by two, a steady rest can also be applied at the same time.
