AI Technical Summary

Technical Problem

During the shoe manufacturing process, the 5Gen material of the cold blank in the lower mold is prone to excessive melting during hot pressing, which can lead to problems such as color bleeding and scorching in the finished product, increasing the scrap rate and production costs.

Method used

The design employs a combination of upper and lower molds, incorporating positioning pillars, positioning holes, and positioning blocks. Bakelite insulation material is used to ensure stable pressure and temperature transmission during hot pressing, preventing excessive melting of the lower mold blank. Production efficiency is improved through a discharge port and hydraulic rods.

Benefits of technology

It effectively avoids excessive melting of the cold blank in the lower mold, reduces the scrap rate of finished products and production costs, improves the stability and processing accuracy of the mold, and enhances production efficiency.

Abstract

The utility model discloses a shoemaking hot-pressing die, and relates to the technical field of shoemaking hot-pressing dies. The EVA pouring mold comprises the lower mold, the upper mold and the functional mechanism, the functional mechanism comprises the upper middle mold and the lower middle mold, the upper middle mold and the lower middle mold are arranged, the upper middle mold and the lower middle mold are made of bakelite heat insulation plate materials, the bakelite heat insulation plate materials have good heat insulation performance, and when EVA pouring materials are heated, the EVA pouring materials are not prone to falling off. According to the technical scheme, part of heat can be effectively prevented from being conducted to the lower die, a cold blank is protected from being affected by overheating, and therefore it is guaranteed that the cold blank and EVA pouring materials are synchronously foamed at the proper temperature, the situations of color crossing, scorching and the like of finished products caused by flowing generated by excessive melting of the lower die cold blank are avoided, the rejection rate and the production cost are reduced, and the production efficiency is improved. And the positioning columns and the positioning blocks are arranged, so that alignment and positioning of the molds are ensured, the product quality problem caused by mold dislocation in the machining process is avoided, and the rejection rate caused by mold dislocation is reduced.
