A Mechanized Unlocking Device for Polyurethane Foam Plastic Mold

Abstract

A mechanized polyurethane foam mold unlocking device, which relates to the field of mechanized manufacturing; includes a base, a mold pushing mechanism, a mold platform, a mold pull-off mechanism, a hydraulic moving mechanism, a mold turning mechanism, a pull-type foaming mold, a mold running car and Positioning mechanism; the mold platform is installed on the upper surface of one end of the base; the mold pushing mechanism is installed above the mold platform; the mold pull-off mechanism is installed in the middle of the base; the hydraulic moving mechanism is installed on the upper surface of the other end of the base; the mold turning mechanism is set On the top of the hydraulic moving mechanism; the position of the mold running car corresponds to the mold turning mechanism; the positioning mechanism is installed on the top of the mold running car; the pull-type foaming mold is installed vertically on the top of the mold running car; Fixing of the foaming mould; the invention realizes the mechanized disassembly and assembly of the mould, by designing the mold as an inner mandrel mold and an outer mould, which are pulled, and equipped with a turning mechanism, a numerical control hydraulic clamping and pulling device.

Description

technical field [0001] The invention relates to the field of mechanized manufacturing, in particular to a mechanized polyurethane foam mold unlocking device. Background technique [0002] Polyurethane foam has the characteristics of low density, high specific strength, low thermal conductivity, and excellent impact resistance. It is widely used in aerospace, aviation, ships, ground construction, food packaging, road transportation and other fields. Among them, closed-cell rigid polyurethane foam has many applications in the heat insulation of the low-temperature propellant tank of the launch vehicle, the launch tube of the weapon type, and the nuclear fuel transportation container. [0003] Rigid polyurethane foam is mostly produced by closed-mold casting to ensure its prefabricated shape and cell strength. According to the traditional production process, the main process of closed-mold pouring is to first use mechanical stirring in the mixing tank to mix A and B materials ...

AI Technical Summary

Problems solved by technology

In this process, the maximum internal pressure of the foaming mold can reach 0.3-0.5MPa. In order to prevent the leakage of raw materials during the foaming process and to release the mold normally, a large number of screws must be used to tighten the mold. The installation and removal process of screws is often a limitation. The bottleneck of improving the production efficiency of closed mold foaming products

The locking and demoulding of rigid polyurethane foam plastics in the prior art has high operating intensity and low production efficiency of products
