Telescopic mold structure and foaming preparation method thereof

Abstract

The invention discloses a telescopic mold structure and a foaming preparation method thereof. The telescopic mold structure comprises an upper cover and a bottom cover, wherein the upper cover covers the bottom cover, and an accommodating space is formed between the upper cover and an inwards concave part of the bottom cover; and a telescopic structure is arranged between the upper cover and the bottom cover, so that the range of the accommodating space can be adjusted; Through the design of the telescopic mold structure, pressurization or multiple times of pressing can be properly carried out according to the requirements of the foaming materials in the foaming preparation method, the compression density between the foaming materials is improved, the heat conductivity is improved, the forming density and thickness of foaming forming can be controlled, the surface flatness is improved, and the product yield is improved.

Description

Technical field [0001] The present invention relates to a mold, and in particular, in the process of a foaming preparation method, a scalable mold and a foaming preparation method of the foamed material can be given by a scalable material at a timely manner. Background technique [0002] The foamed beads are mainly applied to Bai Li Long (Polystyrene, Polystyrene, PS) or other buffer or package, but in recent years, with the new application of shoe, and advertising marketing and propaganda of the footwear industry. After that, the materials of the foaming beads, and the foaming forming technique gradually returns to the mainstream development market, which is received by many manufacturers and developmenters. [0003] At present, the processing of the foamed beads can be mainly divided into two major stages, and the first is to form a foam material to form a particles, the second, introduce the molded beads into the mold. In the middle, the foamed beads are compressed by passing ...

Problems solved by technology

[0004] However, the above-mentioned preparation method requires the foam molding processing plant to invest in additional equipment for introducing high-pressure steam, which not only increases the cost of production, processing and equipment, but also the high-pressure steam equipment is used in the molding process of foam beads. The temperature can usually only reach 150oC, which cannot be applied to other foaming material preparation methods that require high-temperature molding, which adds to the doubts and cost pressure of foam molding processing plants about investing in high-pressure steam equipment
