Mold-clamping sequence control mechanism

Abstract

The invention relates to a mold-clamping sequence control mechanism comprising a turning block which is a column-shaped bar and which is fixedly arranged on a mobile template. A driving surface is provided on an end on a turning block long-side direction. The mechanism also comprises a movable block which can be arranged on a fixed template and which can perform reset movement to the direction of the fixed template. The movable block is provided with a guiding surface which is opposite to and slidably fit with the driving surface, and a bearing part which bears against a middle template. The turning block is used for pushing the movable block to move away from the fixed template along the guiding surface. The middle template bears against the bearing part. The middle template or the turning block pushes the movable block to move away from the fixed template, such that the bearing part does not bears against the middle template, and the middle template can move on and can bear against the fixed template. The invention aims at solving technical problems of easy damage and complicated structure of mold-clamping sequence control mechanisms in prior arts. The invention further provides the mold-clamping sequence control mechanism with the advantages of damage prevention, simple structure, and easy maintenance.

Description

technical field [0001] The invention relates to a mold opening and closing device, in particular to a mold closing sequence control mechanism. Background technique [0002] Some slightly complex plastic products, due to their own structural limitations, cannot be formed by simple molds. Only molds with multiple parting surfaces can be designed to produce them. When the mold has more than two parting surfaces, the opening of the mold The mold clamping sequence usually has strict requirements. [0003] The traditional method is to use high-strength springs to achieve the purpose of mold opening and mold closing respectively, but this method completely depends on the performance of the spring itself. When there is a problem with the spring, the device will not work normally. However, in the actual production process, after frequent use of the spring, various problems often occur due to fatigue, and the failure rate is high, which seriously affects the normal production and pro...
