Injection mold for beach shoes and method for injecting soles of beach shoes using the injection mold for beach shoes

Abstract

The invention discloses a beach shoe injection mould. The beach shoe injection mould comprises a last mould, a clamping mould, a bottom mould and a mould frame, wherein the last mould, the clamping mould and the bottom mould are encircled to form an injection cavity, and the last mould is inserted into a last placing groove. The injection mould is provided with a last fixing piece, and the last mould is fixed on the last fixing piece which can vertically move relative to the mould frame. The injection mould is provided with an ejection device which can extrude the last fixing piece to the injection cavity. The invention also provides a method for injection moulding of soles of beach shoes by virtue of the beach shoe injection mould. According to the invention, the last fixing piece of the beach shoe injection mould is provided with a jacking device, the last mould and an insole can well fit with each other through regulating the jacking device, and the insole is flat, so that the insole and the mould are easy to fit after the mould is locked, the edge of the insole and an arc line of the mould fit with each other closely, and the possibility of material leaking is reduced.

Description

technical field [0001] The invention relates to an injection mold for beach shoes. The invention also relates to a method for injecting sandy beach shoe soles by using a beach shoe injection mold. Background technique [0002] Traditional beach shoes injection molds generally include a last mold, a clamp mold, a bottom mold and a mold frame. The shoe last is surrounded by the clamp mold and the bottom mold to form an injection cavity. The machine directly injects material into the bottom mold cavity, and then the mold is closed and heated. The bottom mold has a shoe last placement groove, the positioning frame of the last mold and the clamping mold are fixed on the mold frame, the last mold is fixed on the last mold positioning frame, the arc of the clamping mold matches the midsole on the last mold, the shoe The last is inserted into the shoe last placement groove, the injection mold is equipped with a shoe last fixing part, and the shoe last is fixed on the shoe last fixi...

AI Technical Summary

Problems solved by technology

However, in the above method, there will be certain errors when clamping the bag, so the last mold in the mold will have a little offset. After the mold is locked, the midsole and the mold are not easy to match, and the edge of the midsole does not match the arc of the mold closely. When entering the injection molding , Polyurethane foams in the mold, high temperature and high pressure are generated in the mold, polyurethane will leak from the gap, serious material leakage occurs, and the edge of the sole will protrude
