The push plate 5 is pushed forward 55mm by the return pin 14, ejecting the plastic product 100 out of the cavity.

[0032] 4. The forklift 15 drives the slider 16 to move outward, disengaging it from the external thread of the plastic product 100. Due to the gap between the forklift 15 and the slider 16, the slider 16 will not open during the thread removal stage.

[0033] 5. The plastic product 100 is removed from the mold cavity.

[0034] The above description is merely a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the specification of the present utility model should still fall within the scope of the patent of the present utility model.
