Abstract

A mold clamping sequence control mechanism, used to control the mold clamping sequence of an injection mold, including a cover plate, a briquetting block, a briquetting block seat, a sliding tongue seat used to connect with the fixed mold plate of the mold, and a seat plate used to connect the fixed mold plate of the mold The connecting pin and the ejector pin used to connect with the movable template of the mold. The sliding tongue seat is provided with a first slot for inserting one end of the ejector pin and a second slot for inserting one end of the latch. The briquetting seat is connected between the cover plate and the Between the sliding tongue seats, the pressing block is installed in the installation hole opened on the pressing block seat. A first spring is provided between the pressing block and the cover plate. The pressing block is pressed against the ejector pin and the latch. Push the first push shoulder of the briquetting block, and one end of the bolt is provided with a step for pressing on the briquetting block. The mold clamping sequence control mechanism of the present invention can control the mold clamping sequence when the molds are clamped, thereby effectively avoiding scrapping of the molds.

Description

Technical field:

[0001] The invention relates to an injection mold, in particular to a control mechanism for controlling the closing sequence of the mold. 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. Conventional molds generally only control the opening sequence of the mold through springs, pull rods, shutters, limit screws, etc., but do not control the closing sequence of the mold. Therefore, when the mold is closed, the ejector plate The inclined top is easily damaged by the inclined core-pulling slider before it is reset, resulting in the scrapping of the mold. Invention content:

[0003] The technical problem to be solved by the present invention is to provide a ...
