Problems solved by technology

[0003] 1. The traditional MD forming mold mainly adopts upper and lower casting. When the sole is formed, the sulfuration and cooling time of the mold are long, the product rate is low, and the energy consumption is high.
[0004] 2. The cooling water channel in the mold is made of stainless steel pipe embedded in the mold for casting. The stainless steel pipe has a low thermal conductivity/cooling coefficient, and looseness between the pipe and the mold is easy to occur. Therefore, the sulfur addition and cooling time in the production process is long, and the energy consumption is high. High, and during the production process of the mold, the stainless steel pipe is easy to oxidize and rust, and there will be water/steam leakage
[0005] 3. The cooling water channel in the mold adopts a sand core casting mold, which has a high defect rate. Since the cooling water channel needs to design the channel size according to the thickness and height of the pro

Abstract

The invention discloses a manufacturing process of an MD and RB integrated forming die. The manufacturing process of the MD and RB integrated forming die comprises the following steps of A, making a circulating through channel model; and B, making a die to form. The MD and RB integrated forming die is mainly used for producing secondary EVA and secondary EVA and a large bottom RB integrally formedproduct; the die material is an aluminum die; and the circulating channel and the aluminum die are integrally formed, and the heat conduction and the cooling are fast; the circulating channel can bemanufactured according to the thickness of the product and the 3D analog mathematical analysis of the height of the side wall, the production of the product is directly influenced by steam and water,the production period is shortened, the productivity is improved, and the energy consumption is reduced; the die is provided with a vacuumizing mechanism, so that the secondary MD fine pattern can beformed well, a bottle ballast with the appearance that the appearance of the secondary MD fine pattern cannot be molded is coated, the die is produced by an automatic machine, and manual operation isreduced.

Description

technical field [0001] The invention relates to a manufacturing method of a mould, in particular to a manufacturing process of an MD and RB integral molding mould. Background technique [0002] The shoe sole mold is mainly used for complete injection of raw materials. There is a circulation passage in the mold. The cooling water circulates and cools in the circulation passage, and finally uses the raw materials in the mold to cool and form. The production of the existing mold mainly includes the following processes and defects: [0003] 1. The traditional MD forming mold mainly adopts upper and lower casting. When the sole is formed, the sulfuration and cooling time of the mold are long, the product rate is low, and the energy consumption is high. [0004] 2. The cooling water channel in the mold is made of stainless steel pipe embedded in the mold for casting. The stainless steel pipe has a low thermal conductivity / cooling coefficient, and looseness between the pipe and th...
