According to described male model thimble mould inscribe mould, wherein, also be provided with the top board spring on the described top board, this top board spring one end places in the top board, and its other end withstands on the lower surface of ejector pin fixed head, when mold closing, makes ejector pin fixed head and top board produce certain distance.
According to described male model thimble mould inscribe mould, wherein, on described ejector pin fixed head, be provided with return pin.
According to described male model thimble mould inscribe mould, wherein, what described boost motor adopted is oil cylinder.
The beneficial effect that the utility model is compared with prior art had is:
The utility model drives top board and thimble and finished product alignment pin by boost motor
OnFollowing operation before die sinking, ejects the Jiao Kou cut-out in the material mouthful groove by thimble, by the finished product alignment pin finished product moulding is ejected mold cavity then, convenient and swift, and the Jiao Kou smooth surface of more manually cutting in product appearance, be difficult for producing burr, the efficient height has been saved the time artificial and that cut material, has avoided the generation of product burr, it is simple to operate, easy to use, provide high the quality and the production efficiency of product, reached the purpose of the residual stub bar of automatic cut-out.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Structural representation when Fig. 1 is a mold closing of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
Referring to Fig. 1, present embodiment male model thimble mould inscribe mould, it comprises upper mounted plate 10, bottom plate 50, mould pin 40, caster 20 and male model plate 30; This male model plate 30 is fixed on the bottom plate 50 by mould pin 40, fixing caster 20 on upper mounted plate 10, the male model benevolence 33 that is used for injecting products is installed on the male model plate 30, being processed with injection molding product in male model benevolence 33 is the mold cavity 31 and the stub bar groove 32 of moulding, this stub bar groove 32 is connected with mold cavity 31, by stub bar groove 32 injection raw material is flow in the mold cavity 31.
In the present embodiment, between bottom plate 50 and male model plate 30, also be fixed with mould pin 40, described male model plate 30 connects firmly with bottom plate 50 mutually by mould pin 40, top board 41 promptly is being installed between the two mould pin below the male model benevolence 33 and ejector pin fixed head 42 above the top board 41 is being installed, be equipped with on this ejector pin fixed head 42 and can pass male model benevolence 33, and finished product knock pin 44 moving up and down, by finished product knock pin 44 the finished product moulding is ejected mold cavity 31; On top board 41, be fixed with the thimble 43 that passes ejector pin fixed head 42 and male model benevolence 33, this thimble 43 is arranged between stub bar groove 32 and the mold cavity 31, the one end is fixed on the top board 41, its other end passes male model benevolence 33, be used to cut off the residual stub bar that finished product remains in stub bar groove 32, residual stub bar is disconnected mutually with shaped article, is the purpose of residual stub bar thereby reach fast shut-off product Jiao Kou.
With top board 41 correspondence positions the ejector 51 that drives top board 41 operations is installed on bottom plate 50, this ejector 51 is fixed in the bottom plate 50 by specializing in screw.What the ejector 51 of present embodiment adopted is oil cylinder, and the piston rod of this oil cylinder connects firmly mutually with top board 41.
Be fixed with return pin 45 on the ejector pin fixed head 42 of this enforcement, return pin 45 is provided with spring, one top board spring 46 also is installed on top board 41, arrive in the top board 41 in one end of this top board spring 46 is put, its other end withstands on the lower surface of ejector pin fixed head 42, make itself and top board 41 keep certain interval, this gap is that the stroke of thimble cut-out hopper is 0.8mm.
Present embodiment begins to start the predelay time from penetrating, and the time moves to pre-progressive position to ejector 51 from going-back position.Oil cylinder drives top board 41 makes thimble 43 drop to the upper surface below of male model benevolence 33, injecting products the mold cavity 31 of male model benevolence 33 in then, and with caster 20 and male model plate 30 closures; After treating that pressurize is finished, start cylinder 32, its drive top board 41 and thimble 43 are moved upward, when the operation stroke is 0.8mm, top board and ejector pin fixed head are conflicted, thimble cuts off the residual hopper in the stub bar groove 32 simultaneously, oil cylinder continues to drive top board and the upwards operation of ejector pin fixed head then, the finished product knock pin is endured out mold cavity with the finished product moulding and is driven upper mounted plate 10 by injection machine again, then open caster 20 and male model plate 30, make injection machine open whole die face, eject moulding moulding and residual stub bar then, the entire die action is finished, and prepares to reset.
The utility model moves its drive thimble 43 and finished product knock pin up and down by ejector 51 is installed on bottom plate 50, thereby before die sinking be that residual stub bar cuts off with the Jiao Kou in the hopper groove 32, the smooth surface that residual stub bar is more manually cut in the shaped article outward appearance, be difficult for producing burr, and high efficiency, saved the time artificial and that cut material, avoided the generation of product burr, it is simple to operate, easy to use, provide high the quality and the production efficiency of product, reached the purpose of the residual stub bar of automatic cut-out.
