Supercritical foaming EVA (Ethylene Vinyl Acetate) sole forming equipment and method

Abstract

The supercritical foaming EVA shoe sole forming equipment comprises an equipment shell and is characterized in that the equipment shell is provided with a window, the equipment shell is fixedly connected with symmetrical first round rods, the symmetrical first round rods are fixedly connected with square plates respectively, the square plates are fixedly connected with first vertical plates, the square plates are fixedly connected with sliding grooves, and the sliding grooves are fixedly connected with second vertical plates. A square plate is fixedly connected with a first L-shaped plate, a first vertical plate is fixedly connected with a box body, a sliding groove is fixedly connected with symmetrical first L-shaped rods, the equipment shell is fixedly connected with an injection molding machine, the injection molding machine fixedly communicates with symmetrical injection molding machine heads, and the first L-shaped plate is fixedly connected with a forming mechanism. The invention relates to the field of industrial processing equipment, in particular to supercritical foaming EVA (Ethylene Vinyl Acetate) shoe sole forming equipment and a supercritical foaming EVA shoe sole forming method. The technical problem to be solved by the invention is to provide the supercritical foaming EVA shoe sole forming equipment and method, so that EVA shoe sole forming is facilitated.

Description

technical field [0001] The invention relates to the field of industrial processing equipment, in particular to a supercritical foamed EVA sole molding equipment and method. Background technique [0002] EVA resin is an ethylene-vinyl acetate copolymer, and the vinyl acetate (VA) content is generally 5% to 40%. Compared with polyethylene, EVA is widely used in foam shoes due to the introduction of vinyl acetate monomer into the molecular chain, which reduces high crystallinity and improves flexibility, impact resistance, filler compatibility and heat sealing performance. materials, functional shed film, packaging film, hot melt adhesive, wire and cable and toys and other fields. [0003] When the EVA sole is formed, the two molds are separated, and due to the foaming of the material, it is easy to stick to the mold. It needs to be removed manually, and the sole temperature is high, which is easy to cause burns to the staff. Moreover, the soles are manually removed for many...

AI Technical Summary

Problems solved by technology

It needs to be removed manually, and the temperature of the sole is high, which may easily cause burns to the staff

Moreover, the soles are manually removed many times, resulting in a reduction in production efficiency.
