The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Consult Fig. 1～shown in Figure 5; a kind of seesaw that the utility model embodiment provides chases after the top mould emptier, comprise a thimble panel 1, be fixedly arranged on the Ejector Retainer Plate 2 of described thimble panel 1 below, be fixedly arranged on described Ejector Retainer Plate 2 belows two fixed blocks 3, be fixedly arranged on a central shaft 41 between described two fixed blocks 3, can be around a spill spin block 4 of described central shaft 41 rotations and a thimble 5 and a position-limited needle 6 of being located at top, described spill spin block 4 both sides respectively.
Particularly, described thimble 5 is arranged in described thimble panel 1 and Ejector Retainer Plate 2, and described thimble 5 is provided with a back-moving spring 51, and described back-moving spring 51 supports and terminates on the described thimble panel 1, when the injection mold matched moulds, set back by described back-moving spring 51 control thimbles 5 and spill spin block 4; Described position-limited needle 6 also is arranged in described thimble panel 1 and Ejector Retainer Plate 2.
As shown in Figure 2; this seesaw chases after the speed rhythm that the top mould emptier quickens to eject product; can adjust by the position that described central shaft 41 is set; by the different ratios of control centre's axle 41 to distance between position-limited needle 6 and the thimble 5; the difference that reaches ejects speed rhythm, ejects the speed requirement to satisfy different products required difference under different situations.
The utility model embodiment also provides a kind of and has comprised that foregoing seesaw chases after the injection mold of top mould emptier, die 7 and back die 8 before comprising, and described preceding die 7 is embedded on the front template 71, and described back die 8 is embedded on the rear pattern plate 81; Described thimble 5 is arranged in described back die 8, and described position-limited needle 6 supports the lower surface that terminates in described rear pattern plate 81.
