Problems solved by technology

[0002] The lower casing of the automobile intake manifold is one of the important parts of the automobile engine. The lower casing of the automobile intake manifold is made through an injection mold. During the injection molding process, most of the glue is wrapped on the core. The injection pressure It will make the oil cylinder slide back, so it is necessary to design the anti-retraction mechanism of the oil cylinder. According to the existing technology, the space in the mold is small, and the design of the oil cylinder is locked, so the mold needs to be enlarged, the use space is large, and the cost is high

Abstract

The invention discloses an anti-return mechanism for an intake manifold oil cylinder of an automobile engine. There is an undercut on the side, and it also includes a core rod for forming the undercut, the core rod is located in the slider, the slider is provided with a first oil cylinder, and the piston rod of the first oil cylinder is connected to the The core rod is connected, and an oil cylinder core-pulling locking mechanism for mechanically locking the core rod is arranged between the slider and the upper die. The invention provides an automobile engine intake manifold oil cylinder with small use space and low cost Anti-return mechanism.

Description

technical field [0001] The invention relates to the field of injection moulds, in particular to an anti-return mechanism for an air intake manifold oil cylinder of an automobile engine. Background technique [0002] The lower casing of the automobile intake manifold is one of the important parts of the automobile engine. The lower casing of the automobile intake manifold is passed through the injection mold. It will make the oil cylinder slide back, so it is necessary to design the oil cylinder anti-return mechanism. According to the existing technology, the space in the mold is small, and the design of the oil cylinder locking requires an enlarged mold, which has a large space and high cost. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is: to overcome the above-mentioned defects of the prior art, and to provide an anti-return mechanism for the oil cylinder of the intake manifold of an automobile engine with small use space ...
