Abstract

The present invention relates to an insulator manufacturing method that enables the insulator to be produced without the production of the insulator when the insulator is manufactured, thereby reducing the time for manufacturing the drawing and reducing the waste of the mold manufacturing cost. The lower mold manufacturing process of forming a lower mold by plastering the lower surface of the floor panel, and the like, and applying a hard synthetic resin to the remaining portions except the hole and the mounting portion formed on the upper surface of the floor panel, and the holes and the mounting portion Is a method of manufacturing an insulator by hot press molding as a top mold manufacturing process for forming an upper mold by forming gypsum on top of the synthetic resin.

Description

How to make an insulator

The present invention relates to the manufacture of an insulator at the beginning of a vehicle, and in particular, it is possible to reduce the time for the production of the drawings by making the insulator without the production of the drawings during the production of the insulator, waste of cost for the production of the wooden mold during the mold production The present invention relates to a method of manufacturing an insulator to reduce the number of times.

In general, an insulator is used in a vehicle to block heat or vibration generated between the engine and the body or the frame, and to insulate and dust. Therefore, in the related art, a drawing is made and a mold is manufactured to manufacture the insulator, but the conventional insulator manufacturing method is shown in FIG. 1.

As shown in FIG. 1, the shape of the insulator suitable for the said panel is shown by figure.

After drawing out as mentioned above, an insulator mold is produced by the said drawing.

After producing the insulator mold, the insulator is molded by hot press molding with the mold.

However, the conventional insulator manufacturing method described above requires a long time (about 20 days) for issuing the drawing because the drawing showing the shape of the insulator is required, and a time for producing a mold even after the drawing is released. 15 days) is required, and it takes a long time to test the product by hot press molding after the production of the mold. there was.

Accordingly, the present invention has been made in order to solve the above-mentioned conventional problems, it is possible to manufacture the insulator mold without drawing out the drawings, and to hot-press the insulator to waste time for drawing out the drawing and to manufacture the mold The purpose is to prevent waste of money.

2 is a process chart showing the insulator manufacturing method of the present invention.

Explanation of symbols for the main parts of the drawings

In order to achieve the above object, the present invention provides a lower mold manufacturing process of forming a lower mold by pouring a cast on the lower surface of a floor panel, such as a product, and casting a cast thereon, and a hole formed on the lower surface of the floor panel. And a mounting portion is formed to have a constant gradient, and the gypsum is applied to the upper part of the sheet wax to lift the mold and pour the casting therein to form an upper mold to hot press the insulator.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 shows a process diagram of the present invention, the operator is to produce a lower mold by applying a plaster on the lower surface of the floor panel and the like already manufactured.

After manufacturing the lower mold as described above, a hard sheet wax or the like is laminated on the lower surface of the floor panel as much as the molding thickness, and the hole and the mounting portion are formed to have a constant gradient, and gypsum is coated on the sheet wax or the like. After application, the casting is poured to form an upper mold.

It is produced by hot press molding using the upper mold and the lower mold manufactured as described above.

Therefore, since the mounting part is already manufactured by hot press molding, further processing is to use the product by drilling holes in the mounting part and trimming the outer part.

As described above, the present invention enables to manufacture an insulator mold without drawing out drawings, and to hot-press the insulator to prevent waste of time for drawing out drawings and cost for making wood molds during mold production. As a result, it is a very useful invention that can shorten the start-up period of the product and increase the efficiency of the work.
