The utility model is achieved through the following technical solutions:
A kind ofly prevent the mould structure turning over bits, comprise die 1, stripper plate 2 is provided with above described die 1, strip matrix cavity 101 is provided with in described die 1, described stripper plate 2 is provided with the strip stripper plate hole 201 corresponding with described matrix cavity 101, the punching pin 3 that cross section is strip is coated with in described matrix cavity 101 and described stripper plate hole 201, described matrix cavity 101 length direction two side is respectively equipped with the scrap guide chute 111 of two through described matrix cavity 101, vertical convex tendon 112 is provided with between scrap guide chute 111 described in two, described scrap guide chute 111 groove depth and described vertical convex tendon 112 height sum are less than product size tolerance, described length direction two side, stripper plate hole 201 is respectively equipped with the chute 211 of stepping down in two through described stripper plate holes 201, stepping down between chute 211 described in two is provided with convex tendon 212, described chute 211 groove depth and the described convex tendon 212 height sum of stepping down is less than product size tolerance, described punching pin 3 drift two side is respectively equipped with and described chute 211 and drift convex tendon 311 corresponding to convex tendon 212 and the drift groove 312 of stepping down, the height of described drift convex tendon 311 and the degree of depth sum of described drift groove 312 are less than product size tolerance.
Prevent the mould structure turning over bits as above, it is characterized in that: described scrap guide chute 111 groove depth and described vertical convex tendon 112 height sum are less than 0.029mm.
Prevent the mould structure turning over bits as above, it is characterized in that: described scrap guide chute 111 groove depth and described vertical convex tendon 112 height sum are 0.011mm.
Prevent strip scrap from turning over the mould structure of bits as above, it is characterized in that: described scrap guide chute 111 and described vertical convex tendon 112 cross section are circular arc.
Compared with prior art, the utility model has the following advantages:
The utility model arranges groove and convex tendon within the scope of product tolerance in matrix cavity and stripper plate hole, product can be met qualified, scrap can be made again to produce salient point with groove along the parallel downslide of matrix cavity, limit scrap to overturn in concave die cavity, play the effect of balance card bits, scrap can not overturn, and parallel through concave die cavity, avoids turning over bits and causes matrix cavity to block.
