[Industrial applications]

 The present invention relates to a counter manufacturing mold used for manufacturing a counter that constitutes, for example, a wash basin or a vanity.

[0002]

[Prior Art]

 As shown in FIG. 5, a counter 10 that constitutes a washbasin, a vanity, etc., has a rectangular horizontal plate portion 10a and an upright portion 10b that extends from the front end of the horizontal plate portion 10a. An apron portion 10c extending downward from the rear end of the horizontal plate portion 10a. The horizontal plate portion 10a is fixed to the lower surface of the counter 10 and corresponds to the size of a washbasin not shown. The opening 10d is formed. The counter 10 having such a shape is manufactured mainly by using the die body 1 and the slide die 2 shown in FIG. 6, or the slide body is integrated with the die body (not shown). Manufactured using a mold. Here, the slide mold 2 is for molding the opening 10d formed in the horizontal plate portion 10a of the counter 10, and the material is wood, glass fiber reinforced plastic (FRP), silicone rubber plate processing. Products or processed products of metal materials such as aluminum are used.

[0003]

[Problems to be solved by the device]

 By the way, the slide mold 2 forms the opening 10d of the counter 10 as described above, and the opening 10d is attached to the lower surface side of the counter 10 so that the hot and cold water flows smoothly into the washbasin (not shown). It is preferable that the diameter is gradually reduced. Therefore, as shown in FIG. 6, the slide mold 2 for molding the opening 10d has a substantially disk shape (or an elliptical disk shape) as a whole. As shown in an enlarged view, it is preferable that the bottom surface 2b is made larger in diameter than the top surface 2a, the peripheral surface 2c is arcuate, and the outer peripheral edge 2d of the bottom surface 2b is sharpened. ..

However, the above-mentioned material of the conventional slide mold 2 has various problems described below. That is, if the above wood is used as the material of the slide mold 2, it is extremely difficult to process it into the shape shown in FIG. 7, and the outer peripheral edge 2d of the pointed bottom surface 2b is easily chipped or cracked. Alternatively, it cannot be repeatedly used for a long time because it easily breaks and corrodes easily. Further, when the above glass fiber reinforced plastic (FRP) is used as a material, it is superior in corrosion resistance as compared with the case of using wood, but the outer peripheral edge 2d of the bottom surface 2b may be sharpened. Not only is it difficult, but cracks, chips, etc. occur as with trees, leaving problems similar to those with trees. In addition, the processed product of the silicone rubber plate does not have the risk of cracking or chipping as described above, but when processed into the shape shown in FIG. 7, not only the surface roughness of the cutting surface of the cutting trace is high, but also the above-mentioned materials Similarly, it is difficult to sharpen the outer peripheral edge 2d of the bottom surface 2b. Also, in the case of a processed product of a metal material such as aluminum, there is no major problem in processing into the shape shown in FIG. 7, but the outer peripheral edge 2d of the bottom surface 2b, which is also sharp, is easily chipped or cracked. There is a high risk of breakage, and since it is sharpened, there is a high risk of damaging the operator's fingers.

Therefore, the present invention has been proposed to solve the problems caused by the materials used as the above-mentioned conventional manufacturing type for counters, especially slide type, and is optimal as an opening formed in the counter. It is possible to provide a counter manufacturing mold that can be easily molded into a shape that corresponds to various shapes, has a low risk of cracking, chipping, or breaking, and a low risk of damaging the operator's fingers. It is intended.

[0006]

[Means for Solving the Problems]

 The present invention has been proposed in order to achieve the above object, and is a manufacturing mold used for manufacturing a counter having an opening for mounting a washbasin, which is at least a mold body. And a slide die mounted on the upper surface of the die body, wherein the slide die is made of a resin which is molded and cured by being cast.

The above-mentioned resin is, for example, condensation type or addition type silicone rubber, epoxy resin, polyurethane, urea resin, Teflon resin, etc. Other resins may be used as long as they can be injected into the mold. However, considering the releasability from the molding die used for molding this slide die, and cracks, chips, and breaks of the slide die, it is preferable to use silicone rubber or silicone resin. Considering the adhesion to the main body, it is preferable to use an elastic silicone rubber.

The slide mold needs to use at least the above resin as a main raw material, but does not necessarily have to be composed of only the resin, for example, a flat core material is embedded inside. May be By embedding such a core material in the slide mold, the resin occupancy rate decreases, and it is possible to manufacture at low cost, and when a resin with high flexibility is used, it is mounted on the mold body. It is easy to handle when placing or removing. Examples of the material of the core material include wood and other hard resins. When wood is used as the core material, the specific gravity of the slide mold is reduced, and the handling becomes easier.

[0009]

[Action]

 According to the counter manufacturing die of the present invention, the slide die is made of a resin that is molded and hardened by being cast, so that the shape most suitable for molding the shape of the opening formed in the counter. In addition, there is less risk of chipping, cracking, breaking, etc. of the outer peripheral edge of the sharpened bottom surface, and there is also less risk of damaging the operator's fingers due to the outer peripheral edge.

【Example】

 Hereinafter, an embodiment of a counter mold according to the present invention will be described in detail with reference to the drawings. As shown in FIG. 6, the counter manufacturing mold according to this embodiment includes a mold body 1 and a slide mold 2, and the slide mold 2 has an area of a lower surface 2b rather than an upper surface 2a as shown in FIG. Is large, the vertical cross-sectional shape is substantially trapezoidal, and the peripheral surface 2c is arcuate and the lower surface outer peripheral edge 2d is sharpened. A disk-shaped core material 3 is embedded inside the slide die 2. In the present embodiment, the slide mold 2 is made of a condensation-type silicone rubber, and the core material 3 is made of wood and processed into a disc shape.

Hereinafter, a method for manufacturing the slide mold 2 will be described. In order to manufacture this slide mold 2, first, as shown in FIG. 2, an upper mold 5 and a lower mold 6 are prepared. In this embodiment, the upper mold 5 is formed by cutting a wooden board into a disk shape, and a through hole 5a having the same shape as the opening 10d formed in the counter 10 shown in FIG. There is. On the other hand, the lower die 6 is a disk having the same diameter as the upper die 5, and is a glass plate processed in this embodiment. Then, as shown in FIG. 2, the upper mold 5 and the lower mold 6 are fixed in combination with each other, and the upper mold 5 and the lower mold 6 form a recess having the shape of the slide mold 2 to be molded. To form. When the fixing of the upper mold 5 and the lower mold 6 is completed, a predetermined amount of the condensation type silicone rubber 8 is injected into the concave portion from above, as shown in FIG. Before the rubber 8 crosslinks, the core material 3 is dropped, and further, the silicone rubber 8 is injected until it becomes flush with the upper surface 5b of the upper mold 5 as shown in FIG. .. Upon completion of such a series of steps, finally, the upper die 5 and the lower die 6 are separated from each other, and the silicone rubber 8 molded in the through hole 5a of the upper die 5 is released to set the slide die 2 above. Get

According to the slide die 2 thus obtained, even if the outer peripheral edge 2d of the lower surface of the slide die 2 is sharpened, there is no risk of breakage, chipping, cracking, etc. There is also no risk of injury to personnel. Moreover, since the slide mold 2 according to the present embodiment is made of the silicone rubber 8, even if the upper surface 1a of the mold body 1 is not completely horizontal and has some distortion, It can absorb strain. Therefore, a small gap is formed between the upper surface of the die body 1 and the bottom surface 2b of the slide die 2, and the risk of the raw material of the counter entering the gap can be effectively avoided. Further, in the slide die 2 described in the present embodiment, since the core material 3 is embedded in the inside thereof, the operation for placing on the upper surface portion 1a of the die body 1 or for removing from the upper surface portion 1a is performed. The sex is also good.

Although the slide mold 2 in which the core material 2 is embedded is illustrated in the above embodiment, the slide mold constituting the present invention does not necessarily have the core material as described above. Further, it is not necessary to use the above-mentioned condensation type silicone rubber as the kind of the resin, and another resin may be used. Further, in the above-mentioned examples, wood was used for the upper mold 5 and glass was used for the lower mold 6 as the material of the manufacturing mold for manufacturing the slide mold, but these molds are not limited to the materials described above. Without being specified, other materials such as a metal material and an inorganic material may be used as long as they are materials capable of molding at least a resin.
