Embodiment
[0052] see figure 1 figure 2 , the compression pin head forming progressive die, including:
[0053] Upper mold 1, upper mold 1 includes upper mold base 1-1;
[0054] Lower mold 2, lower mold 2 includes lower mold base 2-1;
[0055] Core mold sleeve, refer to Figures 14 to 17 , consists of a core set 15 and a mold sleeve 16. The core set 15 is a double split type, and is composed of two symmetrically arranged cores 15-1. The counterbore 15-2 of the pin 11, a mold cover 16 for clamping the core set 15 is set on the outer wall of the core set 15; The notch 16-2 in the mold cover 16 has a notch 16-1 in the middle of the mold cover 16. The cross section of the notch 16-1 is an isosceles trapezoid, and the core group 15 is an isosceles trapezoid shape. 16-1 is the surface connection.
[0056] Two edges of the big end surface of the mold core set 15 are symmetrically provided with jacks 15-3, and the inclination angle and direction of the jack 15-3 are the same as the inclin...
