Description of the drawings
Fig. 1 is rear mold top view of the present utility model；
Fig. 2 is die structure dwg of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is described in further detail.
Fig. 1 and Fig. 2 show schematically show a kind of anticollision mold forming mould according to a kind of embodiment of the present utility model
Tool.
It is a kind of to reduce the one of finished surface vestige and go out four die castings, including front mould 1, rear mold 2, die cavity 3, a cast runner,
Pan feeding mouth 5 and ejection assembly；Front mould 1 is located at 2 upper end of rear mold, and 2 lower end of rear mold is provided with support block 21 and spike 22 supports rear mold 2, mould
Foot 21 supports 2 corner location of rear mold, spike 22 to support 2 centre position of rear mold；Between front mould 1 and rear mold 2 formed a cast runner and
