[ detailed description ] embodiments
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
As shown in fig. 3-5, a three-template core-pulling mechanism is applied to an injection mold, which includes a stripper plate 10, a cavity plate 20 and a cavity insert 30; the three-template inclined core-pulling mechanism comprises a sliding block 40, a sliding block insert 50 and an elastic piece 60; the sliding block 40 is movably arranged in the mother template 20, and one end of the sliding block can extend out of one side, close to the stripper plate 10, of the mother template 20; the slide insert 50 is arranged on the slide 40, and one end of the slide insert can penetrate through the cavity insert 30 to participate in product molding; the elastic member 60 is disposed between the slider 40 and the mother board 20 and can be extended and contracted in a product exit direction of the slider insert 50.
Specifically, in the three-template inclined core-pulling mechanism, the cross section of the sliding block 40 is in an inverted T shape. Wherein, one end of the slide block 40 close to the stripper plate 10 is rounded. Preferably, the slider 40 and the slider insert 50 are integrally formed, so that the assembly precision of the slider insert 50 can be further ensured, and the product forming quality can be improved.
In the three-template inclined core pulling mechanism, the elastic member 60 is preferably a strong spring sleeved on the slider insert 50.
