Description

Manufacturing method of shoe mold by electric pole. {Manufacture method of metal mold for shoes}

The present invention relates to a method of manufacturing shoe molds by electroforming, in which a synthetic resin mold (master) subjected to a conductive treatment is put in an electrolytic solution, and the electrosynthetic treatment is performed by internal electroforming. Melting is to create a shape that fits fashion.

Conventionally, as a method of manufacturing shoe molds, there were a machining method, a casting method, and an electric discharge method. However, the machining method requires a delicate part to be finished by hand because it is difficult to work with precision equipment. In the case of casting with casting, the casting is made by making two castings and cutting them up and down, so the precision is lowered, and the warpage phenomenon occurs due to shrinkage, bubble, etc., which causes casting defects. The working environment such as high heat, dust, noise was weak, and in the case of electric discharge machining method, it is made of carbon or copper, and it has a lot of abrasion when discharging. There was a hindrance of being.

The present invention provides a high-speed electrolytic solution of a synthetic resin type (master) subjected to a conductive process after making a silicone type and manufacturing a synthetic resin type (master) with a shoe sole made of a wooden mold to eliminate the above-mentioned waste. ) It is manufactured by inexpensive manufacturing of shoe molds with delicate surface, high precision and durability through heating process of electro-formed castings, melting the synthetic resin molds and immersing them into existing mold bases, castings or reinforced plastics. If the invention is described in detail according to the process as follows.

1st process

The sole model is made in the wooden shape.

Second Process

The silicon mold is manufactured by the sole model which passed the 1st process.

Third Process

Synthetic resin type (master) is produced from the silicon type manufactured by the second process, and the separation piece and the heterogeneous metal are inserted and manufactured.

4th Process

The surface of the synthetic resin (master) produced by the third process is subjected to conductive treatment.

5th Process

The electroconductive synthetic resin mold subjected to the fourth process is placed in a high-speed electrolytic solution and subjected to electroforming.

6th Process

The cast body after the fifth process is heated to melt the internal synthetic resin (master).

7th Process

The cast product, which has undergone the sixth step, is immersed on the mold base or immersed in a cast or reinforced plastic.

According to the present invention manufactured through such a process, a silicon mold is manufactured using a model made of wood, and a separation piece is inserted into a portion desired to be separated on a synthetic resin mold (master). It is possible to manufacture two or more kinds of castings by one electric pole by using partial separation after electromagnetization. Iii) After immersing the metal, conducting the conductive treatment, and putting it in the high-speed electrolytic solution and immersing it in the mold base, it is completed. Water can be immersed in castings, reinforced plastics, etc., depending on the application.

The present invention has the effect that the surface is delicate and accurate, and can be manufactured with a durable shoe mold while reducing the processing cost and time.
