A pop-up slider mechanism for an injection mold

Abstract

The invention discloses a pop-open sliding block mechanism of an injection mold. The pop-open sliding block mechanism comprises a fixed mold sliding block, slider angle pins are arranged on the fixed mold sliding block, spring holes are formed in the fixed mold sliding blocks, and the axes of the spring holes are parallel to those of the slider angle pins. Compression springs are arranged in the spring holes and abut against the fixed mold sliding block, and a limiting block is arranged at the upper end of the fixed mold sliding block and fixed to a mold frame. A pull hook is arranged at the bottom of the fixed mold sliding block. One end of the pull hook hooks a pull hook check block, and the other end of the pull hook is fixed to a moving mold. The pull hook check block is fixed to the fixed mold sliding block. The fixed mold sliding block moves in the axis direction of the slider angle pins under the common action of the pull hook and the springs, the pull hook is separated from the pull hook check block on the fixed mold sliding block, and the fixed mold sliding block only continues to move under the elastic force of the springs till the fixed mold sliding block touches the limiting block; and ribs and clamping pins on the side face of a plastic part are separated out of the fixed mold sliding block, and the core pulling process is completed.

Description

technical field [0001] The invention relates to the injection mold structure of the lampshade of the front headlight of a passenger car, in particular to a core-pulling slider mechanism for fixing the mold of the lampshade. Background technique [0002] Automobile headlights, as functional parts and exterior parts, are increasingly becoming an important part of car styling and overall appearance, so there are higher requirements for the structure and process of plastic parts. The lampshade requires beautiful and novel appearance, smooth surface, transparent and certain strength. The lampshade and the lamp housing are assembled in the form of clips and clips. The state of motion should be stable, reliable and efficient. [0003] The original core-pulling structure of the fixed mold of the mold uses an oil cylinder to drive the movement of the core-pulling slider to complete the core-pulling and reset actions of the fixed-mould slider. Injection molding can only be produced ...

Problems solved by technology

[0003] The original core-pulling structure of the fixed mold of the mold uses an oil cylinder to drive the movement of the core-pulling slider to complete the core-pulling and reset actions of the fixed-mould slider. Injection molding can only be produced on the top, and the core-pulling and reset process is unstable, and the fixed-mold core-pulling slider has a potential risk of failure
