Embodiment 1

[0057] Polyurethane TPU is used to make shoe soles. It has the advantages of light weight, high strength, good toughness, excellent wear resistance and folding resistance, wide adjustable range of hardness and density, good temperature resistance, anti-skid and oil resistance, and comfortable wearing. It is a kind of A new type of environmentally friendly product, but there will be many problems in the molding process, such as the precise requirements for the mold, there will be shallow foaming, peeling, pores, air bubbles, hydrolysis, shrinkage, etc., resulting in a high defect rate and difficult to deal with in the future. , the mold described in the present invention and the suction molding method using it mainly solve the above-mentioned problems.

[0058] Heat the complete mold to 45-60 degrees, spray the mold with release agent, then put the negative film into the bottom of the mold, then put the TPU film on the bottom mold 1, put down the middle frame 4, and fix it tight...

Embodiment 2

[0061] Heat the mold to 40-50 degrees, spray the release agent, and then put the TPU film with a thickness of 0.01-0.03 on the bottom mold 1 and put down the middle frame 4, fix it, suck the vacuum, let the TPU film directly suck into the mold cavity, and then Polyurethane is poured into the mold cavity, and the mold cover 8 is covered, and the fixing is completed.

Abstract

The invention discloses a shoe sole forming mold and a shoe sole mold sucking forming method using the same. The mold comprises a bottom mold, a middle frame, a mold cover, an electromagnetic attracting device, an oscillator and a stirring device from bottom to top, wherein a mold cavity of which the appearance corresponds to that of a shoe sole is formed in the bottom mold; elastic supporting columns are arranged on the bottom of the bottom mold; the middle frame is pivotally connected to the upper part of the bottom mold in an openable manner; the mold cover is pivotally connected to the upper part of the middle frame in an openable manner; a projection module is arranged on the mold cover and corresponds to a through hole; the electromagnetic attracting device comprises first electromagnets and second electromagnets; the first electromagnets are arranged along the periphery of a surface, which is combined to the middle frame, of the bottom mold and fixedly attract the bottom mold and the middle frame; the second electromagnets are arranged along the periphery of a surface, which is combined to the mold cover, of the middle frame and fixedly attract the mold cover and the middle frame; and the oscillator is arranged on the bottom of the bottom mold so that the bottom mold can vibrate. Shoe sole mold sucking forming can be carried out by the shoe sole forming mold. The shoe sole forming mold is easy to operate, and quality of shoe soles is improved.

Description

technical field [0001] The invention belongs to the technical field of shoe sole processing, and in particular relates to a shoe sole forming mold and a method for shoe sole suction molding by using the same. Background technique [0002] The use of polyurethane TPU to make shoe soles has many advantages, such as: light weight, high strength, good toughness, excellent wear resistance and folding resistance, wide range of hardness and density adjustable, good heat preservation performance, anti-skid and oil resistance, comfortable to wear, etc. A new type of environmentally friendly products. However, the current molds will have many problems in the molding process of using polyurethane to make soles, such as shallow foaming, peeling, pores, air bubbles, hydrolysis, shrinkage, etc., resulting in a high defect rate of sole molding and difficult follow-up deal with the problem. Contents of the invention [0003] The object of the present invention is to solve the above-ment...
