Detailed description of the invention
As shown in Figure 1, moulding cast gate overlap cutter sweep, comprises upper bolster 1, mount pad, spring 4, stripper 5, drift 6, die 7 and die shoe 8, and described mount pad comprises punch fixing plate 2 and connecting plate 3, and described drift comprises punch and drift afterbody.
Described upper bolster 1 center is provided with fixing hole 16, described upper bolster 1 lower central position is vertically provided with punch fixing plate 2, below described punch fixing plate 2, afterbody is provided with connecting plate 3, described connecting plate 3 edge exceeds punch fixing plate 2, described connecting plate 3 edge is provided with bolt hole, described drift 6 is arranged on punch fixing plate 2 center vertical lower, described drift 6 center is provided with punch hole 12, described punch is arranged in the punch hole 12 at drift 6 center, described drift 6 afterbody is also provided with boss, below described drift 6, afterbody is provided with stripper 5, described stripper 5 center is provided with stripper through hole 10, the edge of described stripper through hole 10 is provided with bolt connecting hole, spring 4 is provided with between described connecting plate 3 and stripper 5, described spring 4 is arranged on connecting plate 3 and stripper 5 by bolt,
Described die 7 is vertically set on below stripper 5, on described die 7, plane is provided with the groove 13 with boss same shape, described die 7 side is provided with keyway 15, below described die 7, afterbody is provided with epitaxy part, described die 7 center is provided with punching 14, described epitaxy part is provided with bolt connecting hole, and described lower seat fixed head is arranged on below die 7, and described die shoe 8 center is provided with fixing hole 16.
Described boss diameter is less than drift 6 diameter, and described boss diameter is consistent with groove 13 diameter.
Described drift 6 and boss, die 7 and epitaxy part are formed in one.
The shape of described connecting plate 3, upper bolster 1, die shoe 8 and die 7 epitaxy part can be rectangle, circle and polygon.
The horizontal both sides, punch hole 12 of described drift 6 lower plane are provided with installing hole 11.
