A molding device and process for rubber sponge barrel-shaped profiles

Abstract

A molding device and process for a rubber sponge barrel-shaped profile, the device comprises a molding core rod, a shaping die with the same shape, and a lower die of the shaping die, and the shaping core rod and the top of the lower die of the shaping die are matched and adapted to shape the shape. A first U-shaped barrel-shaped filling cavity is arranged inside the mold, and a second U-shaped barrel-shaped filling cavity is arranged inside the lower mold of the forming mold; a kind of cell can be prepared by the above-mentioned device through the process of setting, vulcanization, and post-processing segmented molding The sponge barrel-shaped profile with uniform and stable size, micro-pore closed structure and low apparent density; the invention has the advantages of simple structure, simple process, practicality and high efficiency.

Description

technical field [0001] The invention relates to the technical field of rubber sponge production, in particular to a molding device and process for a rubber sponge barrel-shaped profile. Background technique [0002] At present, rubber sponge products have been widely used, but at present, most of the rubber products are produced by using traditional molds and traditional rubber sponge products molding process. According to the filling amount of the molding die cavity, it is divided into two types: 1) Full mold vulcanization is the rubber compound. Fill the entire mold cavity; 2) Before full mold vulcanization, that is, the rubber compound does not fill the entire mold cavity. Both processes have problems of uncontrollable structure, uneven cell structure, and high open porosity. SUMMARY OF THE INVENTION [0003] In order to overcome the above-mentioned deficiencies of the prior art, the purpose of the present invention is to provide a molding device and process for a rubbe...

AI Technical Summary

Problems solved by technology

[0002] At present, rubber sponge products are widely used, but most of the rubber products continue to use traditional molds and traditional rubber sponge product molding processes. According to the amount of rubber filling in the molding cavity, there are two types: 1) full mold vulcanization, that is, rubber Fill the entire mold cavity; 2) The rubber material does not fill the entire mold cavity when the mold is not fully vulcanized. Both processes have problems such as uncontrollable structure, uneven cell structure, and high porosity.
