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