Abstract
The utility model discloses a novel ejector mechanism of a plastic mould. The ejector mechanism comprises a front mould and a rear mould, and is characterized in that a front mould core and a rear mould core are respectively arranged between the front mould and the rear mould, a floating core is arranged on the rear mould, the upper end of the floating core is arranged in the rear mould core, and an ejector pin assembly capable of ejecting a product is arranged on the rear mould. The novel ejector mechanism of the plastic mould aims at overcoming the defects in the prior art, is simple in structure, and can effectively prevent a product with a recess from being strained when the product is ejected out.
Description
Technical field
The utility model relates to a kind of plastic mould Novel ejection structure.
Background technology
Existing plastic mould, have a lot of product structures complicated, have recess on product, existing mould and the corresponding core of described recess are generally all fixed, in die sinking, generally by thimble, directly ejected product is disposable, the generation of phenomenon such as tend to like this cause that product is pulled.So existing plastic mould awaits further perfect.
Utility model content
The purpose of this utility model is in order to overcome weak point of the prior art, provides a kind of simple in structure, can effectively prevent from being provided with the plastic mould Novel ejection structure that the product of recess is pulled when ejecting.
In order to achieve the above object, the utility model adopts following scheme:
A kind of plastic mould Novel ejection structure, include front mould and rear mold, it is characterized in that: between described front mould and rear mold, be respectively equipped with front cavity and rear cavity, in described rear mold, be provided with floating-type core, described floating-type core upper end is arranged in described rear cavity, is provided with the thimble assembly that product can be ejected in described rear mold.
A kind of plastic mould Novel ejection structure as above, it is characterized in that described thimble assembly includes Ejector Retainer Plate, on described Ejector Retainer Plate, be provided with thimble, on described Ejector Retainer Plate, be provided with and described thimble can be fixed on to the thimble panel on described Ejector Retainer Plate.
A kind of plastic mould Novel ejection structure as above, is characterized in that being provided with connecting hole on described Ejector Retainer Plate and thimble panel, and described floating-type core is movably arranged in described connecting hole.
A kind of plastic mould Novel ejection structure as above, is characterized in that by screw, fixing between described Ejector Retainer Plate and thimble panel.
A kind of plastic mould Novel ejection structure as above, is characterized in that being provided with guider between described front mould and rear mold.
A kind of plastic mould Novel ejection structure as above, is characterized in that including at described guider the lead being arranged in rear mold, is provided with guide pin bushing on front mould, and described lead is arranged in described guide pin bushing.
A kind of plastic mould Novel ejection structure as above, is characterized in that described front mould includes front mold base, and described front cavity is arranged in described front mold base, on described front mold base, is provided with front mould panel.
A kind of plastic mould Novel ejection structure as above, it is characterized in that described rear mold includes rear mold base, described rear cavity is arranged on described rear mold base, on described rear mold base, is provided with rear mold panel, between described rear mold base and rear mold panel, is provided with square iron.
In sum, the utility model with respect to its beneficial effect of prior art is:
The utility model is simple in structure, is provided with floating-type core in rear mold, in die sinking, under the effect of injector push rod, promotes Ejector Retainer Plate, drives thimble, makes moulding depart from internal mold.Meanwhile, due to the effect of moulding center recess shape, force moving core to move with moulding, through after certain stroke, thimble continues to eject, and moving core is motionless, and thimble forces moulding to eject from moving core.Product ejects at twice, and the effectively less pulling force of product with mould, effectively prevents the phenomenon appearance of pulling.
