In description of the invention, it is to be understood that "front", "rear", "left", "right", "upper", "lower" etc. refer in term
The orientation or positional relationship shown is to be based on the orientation or positional relationship shown in the drawings, and description merely for convenience is of the invention and simplifies
Description, rather than the device or element of indication or suggestion meaning must have a particular orientation, and are constructed and grasped with specific orientation
Make, therefore is not considered as limiting the invention.
As shown in Figure 1-Figure 3, a kind of injection mold, including cover half 1 and the dynamic model being flexibly connected with cover half 12, cover half 1
Interior to be equipped with for the molding injection molding cavity 3 of molten plastic, dynamic model 2 is equipped with the injecting hole for injection molding, and the lower section of injection molding cavity 3, which is equipped with, to be used
In the stripper apparatus that will form plastic ejection, stripper apparatus includes the motor 4 set on 1 side of cover half, and the output shaft of motor 4 passes through
Shaft coupling is fixedly connected with bidirectional helical bar 5, and the one end of bidirectional helical bar 5 far from motor 4 is connected by bearing and 1 inner wall of cover half
It connects；It is threadedly coupled on bidirectional helical bar 5 there are two symmetrical movable block 6, the both ends of screw thread, which are fixed with, prevents the slippage of movable block 6
Limited block 7；The upper end of two movable blocks 6 is hinged with connecting rod 8 respectively, and the top of connecting rod 8 is equipped with top plate 9, on the lower end surface of top plate 9
If slidably connecting sliding block 11 in sliding slot 10 there are two symmetrical sliding slot 10, the upper end of connecting rod 8 is cut with scissors by sliding block 11 and top plate 9
It connects；Top plate 9 is equipped with the mandril 12 for that will form plastic ejection, and the lower end of mandril 12 is fixed with buffer spring 13, injection molding cavity 3
Bottom be equipped with the through-hole that ejects for mandril 12；
