EPS plastic foam demolding process

Abstract

The invention belongs to the technical field of foam production, and particularly relates to an EPS plastic foam demolding process. A demolding forming machine adopted in the technology comprises a forming mold base, a mounting plate, an elastic anti-sticking sleeve and a control unit, wherein the control unit comprises two first shafts, two rotating wheels, two cams, a belt and a push rod. According to the EPS plastic foam demolding process, the anti-sticking sleeve and the control unit are arranged, the separation difficulty of a foam product from a forming mold cavity after forming is reduced through the arrangement of the anti-sticking sleeve, meanwhile, the control unit adopts the two first shafts, the two rotating wheels, the two cams, the belt and the push rod, the side wall, makingcontact with the foam product, of the anti-sticking sleeve is separated from the foam product more easily, the foam product demolding work is achieved, operation is convenient thoroughly, generationof sewage is completely eradicated, the environment is improved, the subsequent procedure of drying the foam product is reduced, thereby greatly improving the production efficiency of the foam product.

Description

technical field [0001] The invention belongs to the technical field of foam production, in particular to an EPS plastic foam demoulding process. Background technique [0002] EPS is a rigid cellular foam of polystyrene (PS), which has good heat insulation and shock absorption, high compressive strength, very light weight and moisture resistance. Its uses include building heat insulation and sound insulation, side walls and Covering of interior walls, packaging materials and disposable packaging containers. [0003] The existing processing of EPS foam plastics is to put EPS raw material particles into the film cavity, use steam to input foam, and then pass water in the mold to cool, so that the foam product is separated from the metal mold so that the mold body and the foam product are separated. The method of water vapor demoulding will generate a large amount of sewage, which is not conducive to environmental protection, and the plastic products after demoulding need to be...

AI Technical Summary

Problems solved by technology

[0005] In order to make up for the shortcomings of the existing technology and solve the problem that the existing water vapor demoulding method will generate a large amount of sewage, which is not conducive to environmental protection, and the plastic products after demoulding need to be dried, which increases the processing procedure and affects the production efficiency. , a kind of EPS plastic foam demoulding process that the present invention proposes
