Shoe sole injection mold and injection molding method thereof

Abstract

The invention provides a shoe sole injection mold and an injection molding method thereof. The shoe sole injection mold is used for a shoe sole where a spiked shoe is integrally formed, and comprisesa lower mold and an upper mold. The lower mold is provided with a shoe sole molding cavity, the bottom face of the shoe sole molding cavity is composed of a shoe sole face and a shoe upper face arranged on the outer side of the shoe sole face in a surrounding manner, grooves matched with spikes are formed in the shoe sole face, and a prefabricated outsole with spikes is fixed in the area of the shoe sole face through inserted connection with the grooves. The upper mold is hinged to one side of the lower mold and is provided with a shoe upper peripheral edge clamping opening. After mold compounding, the shoe upper peripheral edge clamping opening and the shoe sole molding cavity form a shoe sole mold cavity. The method comprises the steps that after the prefabricated outsole is placed in the lower mold, shoe sole molding liquid is injected into the shoe sole molding cavity, then the upper mold and the lower mold are compounded, the shoe sole mold cavity is formed by the shoe upper peripheral edge clamping opening and the shoe sole molding cavity, and after cooling, the prefabricated outsole can be integrally formed on a vamp. According to the shoe sole injection mold and the injection molding method thereof, the manual cost is effectively reduced, the capacity is increased, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of shoemaking molds and sole attachment methods, in particular to a shoe sole injection mold and an injection molding method thereof. Background technique [0002] Shoe molds usually refer to molds for sports shoes, beach shoes, slippers, rubber shoes and other footwear, among which sports shoes are the main ones. Mold refers to various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping, stretching and other methods to obtain the required products. [0003] The trend of sports shoes has not only focused on shape design and popularity, but also function and comfort have become one of the key points. Especially for the part of the sole, the major sports shoe manufacturers have spared no effort in R&D and innovation. Therefore, shoe sole mold factories are faced with demands such as changes in free-form shoe shapes, ...

Problems solved by technology

The patent uses rubber injection molding, but the rubber sole is not suitable for making sports shoes, especially football shoes, because the rubber injection sole is relatively heavy and there is a risk of easy degumming. In addition, the rubber sole injection mold is only suitable for To make non-spike shoes, and its production method is not suitable for spiked shoes such as football shoes, which need to be provided with better cushioning and shock-absorbing capabilities to prevent impacts and bumps during sports, which may cause foot injuries.

[0006] At present, most traditional sports shoes such as football shoes and other spiked shoes use manual glue brushing to fix the sole and upper. This method has low production capacity. Poor, the strength of repeated glue brushing is high, and the sports shoes made are prone to degumming. In addition, the glue used has a certain degree of pollution. Workers who work in a polluting environment for a long time will have a greater impact on the body. harm
