Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
At present, the enhancement layer of main friction plate for cam driver adopts polymer composite to make, and when making, first needs artificial cutting blanking, cut out suitable blank material, due to artificial cutting, little time large during the hair billet size cut out, dimensional accuracy is difficult to ensure, affect outward appearance and the performance of product, and labour intensity is high, production efficiency is low, also wastes material.
Adopt this mould, can problems of the prior art be solved.
Concrete structure of the present utility model and use principle is described in detail below for embodiment.
Embodiment one
Structure of the present utility model comprises the upper die and lower die that split is arranged, and described patrix is provided with top clamping plate 1, spring connecting gear and cutting mechanism from top to bottom in turn, and described counterdie comprises base 14 and the limited post 13 be located on base 14 and backing plate 12.Described top clamping plate 1 is fixedly linked with four-column hydraulic press.
