Abstract

The invention relates to a mechanism for controlling a mold closing sequence of a mold, which is used for controlling the mold closing sequence, the mechanism comprises a cover plate, a lock block, a lock block seat, a sliding-tongue seat used for connecting with a mold solid plate, a bolt used for connecting with a mold solid seat plate and a lifting pin used for connecting with a mold movable template. A first slot used for being inserted by one end of the lifting pin and a second slot used for being inserted by one end of the bolt is provided on the sliding-tongue seat, the lock block seat is connected between the cover plate and the sliding-tongue seat, in an installing hole opened by the lock block on the lock block seat, a first spring is provided between the lock block and the cover plate, the lock block is placed against the lifting pin and the slot, a first pushing shoulder used for pushing the lock block is provided at one end of the lifting pin, and a step used for pressing the lock block is provided at one end of the slot. When the mold is closed by the mold, the mechanism of the invention can control the mold closing sequence of the mold, so that the abandonment of the mold can be effectively avoided.

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 ...
