[detailed description of the invention]
Refer to shown in Fig. 2, it depicts the structural representation of double injection mould secondary ejecting mechanism of the present invention.
Double injection mould secondary ejecting mechanism of the present invention, described double injection mould comprises first and penetrates master mold, second and penetrate master mold and two identical male models, described male model comprises bottom plate 100, described first penetrates master mold coordinates injection moulding ebonite with male model, described second penetrates master mold coordinates injection moulding flexible glue with male model, and this double injection mould secondary ejecting mechanism comprises:
At least two limited blocks 200, it is fixed on the bottom plate 100 of described male model;
First liftout plate 300, it is movable is located on described limited block 200, this first liftout plate 300 comprises the first upper ejector plate 310 and first time liftout plate 320, this first upper ejector plate 310 and first time liftout plate 320 are connected and associated movement by screw, also be provided with the first ejector bar 700 below this first liftout plate 300, this first ejects push rod 700 for being ejected by the first liftout plate 300;
Second liftout plate 400, it is movable is located on above-mentioned first liftout plate 300, this second liftout plate 400 comprises the second upper ejector plate 410 and second time liftout plate 420, this second upper ejector plate 410 and second time liftout plate 420 are connected and associated movement by screw, the second ejector bar 800 is also provided with below this second liftout plate 400, this the second ejector bar 800 is for ejecting the second liftout plate 400, this the second ejector bar 800 passes from above-mentioned first liftout plate 300, being provided with corresponding spatial accommodation in this first liftout plate 300 wears wherein for this second ejector bar 800,
