Core pulling structure and plastic injection mould

The invention discloses a core pulling structure and a plastic injection mould. The core pulling structure comprises a first sliding block, a second sliding block, a guide block and a driving mechanism; the lower end of the second sliding block is connected to a traction surface through a traction mechanism; the extension direction of the traction mechanism is in a second inclined direction; the guide block is fixedly arranged on a lower mould plate of the plastic injection mould and provided with a guide surface facing towards the second sliding block; the second sliding block is connected to the guide surface through a guide mechanism, and the extension direction of the guide mechanism is in a first inclined direction; the driving mechanism comprises a driving rod and a driving hole, wherein the driving rod is arranged on an upper mould plate, and the driving hole is formed in the first sliding block; the driving rod extends from the upper right direction to the lower left direction. According to the technical scheme, the core pulling structure of the plastic injection mould can be simplified, and the movement stability of the plastic injection mould in the batch production process can be improved.
