A plastic mold release device

Abstract

The invention discloses a demoulding device for a plastic mold, which comprises a mounting base, a fixed support plate, a fixed frame, a mold mechanism, an ejection mechanism, a top plate, a buffer piece and an auxiliary buffer mechanism. A fixed support plate, the ejection mechanism is fixedly installed on the top of the installation base, the fixed frame is located above the ejector mechanism, and both sides of the fixed frame are fixedly connected with two fixed support plates, and the mold mechanism is fixedly installed on the fixed frame Inside, this plastic mold release device can effectively limit the upper mold when the plastic mold is demolded, and at the same time provide a buffer capacity to prevent the upper mold from collapsing or popping up when it is ejected from the mold, thereby effectively reducing the plastic At the same time, when the spring elasticity of the device is not enough after long-term use, the spring can be quickly replaced to ensure efficient buffering and effectively prevent the upper mold from collapsing or flying.

Description

technical field [0001] The invention relates to the technical field of plastic molds, in particular to a plastic mold demolding device. Background technique [0002] Plastic mold is the abbreviation of a combined mold for compression molding, extrusion molding, injection molding, blow molding and low foam molding. series of plastic parts. [0003] However, in the process of processing the plastic parts in the existing plastic mold, when the plastic mold is demolded, the upper mold is easily disintegrated directly and the upper mold is easily disintegrated during the process of ejecting the upper mold with the existing ejector and demolding device. The upper mold that bounces, collapses or pops up will not only bring great safety hazards, but also affect the quality and efficiency of demoulding of plastic parts. To this end, we propose a plastic mold demolding device. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a plastic mold demol...

Problems solved by technology

[0003] However, in the process of processing the plastic parts in the existing plastic mold, when the plastic mold is demoulded, the existing ejection and demoulding device is easy to directly collapse the upper mold and cause the upper mold to collapse. Flying, and the collapsed or ejected upper mold will not only bring great safety hazards, but also affect the quality and efficiency of plastic part demoulding. Therefore, we propose a plastic mold demoulding device
