Problems solved by technology

And when wanting to make a kind of sole that has EVA and rubber compound, common way is first after the EVA midsole and rubber outsole are molded respectively, artificially use glue to bond the two together. The efficiency is low, and another reason is that the precision of the mold is not enough, the precision of the product size is not enough, and the product quality cannot be improved. This is the shortcoming

Abstract

The invention provides a combined shoe mold of an once molding EVA and rubber combined sole, which comprises an upper mold, a middle frame, a middle plate and a bottom mold, wherein the rear side of the bottom mold is respectively provided with a rib plate along two transverse sides, a horizontal n-shaped guide groove is arranged on each rib plate, the rear side edge of the middle frame is provided with a pivot, two axial ends of the pivot are arranged in the n-shaped guide grooves in a sliding manner, the middle plate is arranged between the middle frame and the bottom mold, and the rear side of the middle frame is connected with the rear side edge of the upper mold through a hinge.

Description

technical field [0001] The invention relates to a combined shoe mold, which is used for one-time molding of EVA and rubber combined shoe soles. Background technique [0002] As we all know, EVA resin is characterized by good softness, rubber-like elasticity, good flexibility at -50°C, good transparency and surface gloss, good chemical stability, anti-aging and resistance Good ozone intensity, non-toxicity, good blendability with fillers, good coloring and molding processability, etc., so people widely use EVA to make shoe soles, refer to figure 1 The EVA foam molding mold includes an upper mold 1' and a bottom film 2', one side of the upper mold 1' and the bottom film 2' is connected by a hinge, and the joint part of the upper mold 1' and the bottom film 2' forms a hollow The mold cavity suitable for EVA injection foam molding. Similarly, rubber has the advantages of firmness, strong wear resistance, etc., and it is also widely used in the production of shoe soles. Refer t...
