Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method of manufacturing a bathroom unit.

Conventional Structure and Problems Generally, in a bathroom unit, a washing area 1 and a bathtub 2 are integrally formed, as shown in FIG. This bathroom unit is made by injection molding, and the washing area 1 is deformed after being removed from the mold. Therefore, as shown in FIG. 2, a straightening mold 3 and a vise 4 were used to correct the problem, and a channel (reinforcing beam) 5 was connected to the outer bottom of the bathroom unit as shown in FIG. This increases the number of man-hours and is troublesome, which affects the product cost.

OBJECTS OF THE INVENTION The present invention takes into account the above-mentioned conventional problems and aims to provide a method of manufacturing a bathroom unit that does not require any correction work.

Structure of the Invention In order to achieve the above-mentioned object, the present invention comprises a glass fiber bathroom unit base material in which the connecting part of the washing area and the bathtub part is formed in a substantially V-shape on the sides and connected, and is fitted into a lower mold to form a T-shape. The shaped reinforcing material is aligned with the outer bottom surface of the bathroom unit base material, a part of it is fitted into the V-shaped part, and the upper mold is assembled with a gap formed between the surfaces of the bathroom unit base material and the reinforcing material. This is a method of manufacturing a bathroom unit that injects resin and integrates a T-shaped reinforcing material on the outer bottom, which has the effect of reducing the number of steps required for straightening the washing area.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 4 to 8. In the figure, 6 is a lower mold for forming the bathroom unit floor, 7 is a bathroom unit base material made of glass fiber, and the connecting part C between the washing area A and the bathtub part B is formed into a roughly V-shaped side surface. ing. first,
Gel coat resin is applied to the surface of the lower mold 6 by spraying or the like, and then a glass fiber bath unit base material 7 formed using a separate mold is placed on the lower mold 6 as shown in FIGS. 4 and 5. Cover. Next, two T-shaped reinforcing members 8 integrated with plywood boards 8' are placed along the outer bottom surface of the bathroom unit base material 7, and a portion is fitted into the V-shaped part, as shown in FIG. The boss portion 9 enters the opening between the plywood plates 8' through the gap t.
An upper mold 9 having a shape of 1.a is placed thereon, and a resin 11 such as polyester is injected through a nozzle 10 as shown in FIG. In addition, the boss portion 9a of the upper die 9
The meaning of having the descending piece 8b is that the thickness of the resin is made equal to prevent resin sink. Since the T-shaped reinforcing material 8 is integrated during the molding of the floor pan, it is possible to eliminate the conventional process of fixing it to the straightening mold after molding and demolding, and then attaching the reinforcing material.
Cost can be reduced.

As described above, according to this embodiment, it is possible to eliminate the process of attaching reinforcing materials after molding and demolding, and the process of covering and fixing the deformation on the straightening mold again after demolding, resulting in cost reduction. do.

Effects of the Invention As is clear from the description of the embodiments above, according to the present invention, the following effects can be obtained.

(1) Costs can be reduced by eliminating the process of attaching reinforcing materials after molding and demolding.

(2) Since straightening after demolding can be reliably performed using the T-shaped reinforcing material, the straightening process after demolding can be reduced and costs can be reduced.
