Second step, it is located on described the second thimble, during this second step end face matched moulds, is snapped on described upper ejector plate;
Flexible member, it is sheathed on described the second thimble, and an end of this flexible member is connected in described second step bottom surface, and the other end of this flexible member is connected on described bottom plate.
Preferably, the distance that described upper ejector plate moves to described male model plate bottom surface is greater than the distance that described first step moves to described male model plate bottom surface.
Preferably, described flexible member is spring.
The utility model secondary ejecting mechanism has been realized the Double-ejection of product by the control to stroke, and utilize ejecting with spacing of the first thimble to realize that product has the moulding of higher glue position or more male model infrastructure product and ejects, this mechanism also is applicable to the mechanisms such as male model forced stripper mechanism, and this secondary ejecting mechanism has the following advantages:
(1) this secondary ejecting mechanism just can reach the effect of Double-ejection without increasing other complicated die structures;
(2) this secondary ejecting mechanism is simple in structure, and easy accessibility is flexible, and mechanism performance is safe and reliable;
(3) this secondary ejecting mechanism has reduced the complexity of the product mold structure that needs Double-ejection, shortens mold height, has solved and has needed four blocks of plates to realize the drawback of Double-ejection, and greatly reduced the cost of mould.

Fig. 1 illustrates the structural representation into the prior art secondary ejecting mechanism.
Fig. 2 illustrates as the structural representation of the utility model secondary ejecting mechanism in the matched moulds state.
Fig. 3 illustrates as the structural representation of the utility model secondary ejecting mechanism in die sinking the first state.
Fig. 4 illustrates as the structural representation of the utility model secondary ejecting mechanism in die sinking the second state.
[specific embodiment]
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
Referring to Fig. 2 illustrates, the utility model provides a kind of secondary ejecting mechanism, it is applied to die for molding product 100, these product 100 bottom surfaces have a barb 101, this mould comprises male die core 210, male model plate 200, upper ejector plate 220, lower liftout plate 230 and bottom plate 300 from top to bottom, and this secondary ejecting mechanism comprises:
The first thimble 400, its main body is located in described male die core 210 and male model plate 200, and the upper end of this first thimble 400 fits in this product 100, and described upper ejector plate 220 is fixed in the lower end of this first thimble 400;
The second thimble 500, its main body is located in described male die core 210 and male model plate 200, the upper end of this second thimble 500 coordinates the barb 101 of this product 100 of moulding and this product, and the lower end of this second thimble 500 is passed described upper ejector plate 220 and lower liftout plate 230 and is located in described bottom plate 300;
