Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are only some embodiments, but not all embodiments of the present invention.

Example (b):

referring to fig. 1-4, the present embodiment is a punching wedge mold structure, including a lower template 1, a lower mold core 11 disposed in the lower template 1, an upper template 2, and an upper mold core 21 disposed in the upper template 2, wherein a plurality of wedge bases 12 are disposed in a circumferential direction of the lower mold core 11, a plurality of wedge assemblies 22 corresponding to the wedge bases 12 are disposed in a circumferential direction of the upper mold core 21, a circumferential edge of the upper mold core 21 is an inward concave structure 3, an edge of the lower mold core 11 is an outward convex flanging structure 31 of a molded product corresponding to the inward concave structure 3, and a punch 4 penetrating through the inward concave structure 3 and extending to the outward convex flanging structure 31 is disposed in the wedge assembly 22.

Be equipped with the dirty tank 5 that is located 11 below on the lower bolster 1, the empty dirty tank 5 tops of arranging in of lower mould benevolence 11, the position of 4 products that punch a hole of drift is located the top of dirty tank 5, and the waste material that 4 drifts out of drift falls into in dirty tank 5.

The wedge base 12 comprises a plurality of bases 6 arranged on the lower template 1, the inner side of each base 6 is provided with an inclined surface 61, and the inclined surfaces 61 are provided with wedge blocks 62.
