Description
Technical field
The utility model relates to a kind of ejector sleeve structures of mold, in particular to a kind of to can be used for the mould of car lamp being buckled to
Draw material ejector sleeve structure.
Background technique
Ejector sleeve is also push pipe, hollow thimble, is generally used cooperatively with thimble, is called ejector sleeve needle assemblies, is plastic mould
One of accessory.There are straight body type ejector sleeve and stepped ejector sleeve etc., when in use, ejector sleeve covers on thimble, and ejector sleeve can be opposite
Thimble moves up and down, so that product ejection of the packet on thimble be gone.
As product structure becomes increasingly complex, product surface has more button bit.Plastic product mostly with back-off passes through
Injection molding, raw material are cooled and shaped by hot flow path injection type chamber.Because the oral area of hot flow path is there are also one section of cold burden head, it has been molded
Cheng Hou, cold burden head may break in cover half hot runner system, influence going on smoothly for production.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the utility model, which provides one kind, can smoothly eject zero, automobile
The drawing material ejector sleeve structure for taking button to of part shaped article.
The technical scheme in the invention for solving the technical problem is:
It is a kind of can be used for back-off mould of car lamp drawing material ejector sleeve structure, including face mould panel, solid plate, moving template,
Bottom plate, the ejector retainner plate on bottom plate and ejector sleeve core；The solid plate is equipped with hot flow path, is equipped with and production in the moving template
The type chamber that product shape matches, glue enter type chamber by hot flow path；The moving template is connected with bottom plate screw, the ejector retainner plate
Between the moving template support block；The die top that pushes away is equipped with the taper head to match with the back-off of car light part；The top
Needle plate, which is equipped with, draws material ejector sleeve structure；The ejector sleeve set for drawing material ejector sleeve structure to include ejector sleeve core and be set in outside ejector sleeve core；
The ejector sleeve core top circumference is equipped with groove, and the die bottom that pushes away is equipped with the back-off groove that cooperate with the groove, it is described
Catching groove is the arc groove of two circle circular arcs, and the ejector sleeve core and the ejector sleeve core are clamped by arc groove.
Further, the bottom plate is equipped with small pressing plate, and the ejector sleeve core is located on small pressing plate；The ejector sleeve set is located at described
Above ejector retainner plate, withstands and push away die bottom.
Taper head of the utility model when in use above ejector sleeve core integrally gos deep into cold runner, at the top of ejector sleeve core and circular arc
Cold burden handle is pulled down disengaging hot runner system by slot clamping, the ejector sleeve core pulling force downward by ejector sleeve core when mold opens.Ejection
When ejector sleeve core it is fixed, ejector retainner plate moves upwards, drive ejector sleeve set move upwards.Ejector sleeve set pushes cold runner, makes cold runner
It is detached from ejector sleeve core.
The utility model has the beneficial effects that: the drawing material ejector sleeve structure is simple, do not increase die cost；It can smoothly eject
Cold burden head reduces rejection rate, goes on smoothly production.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in Fig. 1 ~ 5, a kind of drawing material ejector sleeve structure can be used for the mould of car lamp with back-off, including it is face mould panel 1, fixed
Template 2, moving template 3, bottom plate 7, ejector retainner plate 6 and ejector sleeve core 14 on bottom plate 7；The solid plate 2 is equipped with hot flow path
12, the moving template 3 is interior to be equipped with the type chamber to match with 10 shape of product, and glue enters type chamber by hot flow path 12；It is described dynamic
Template 3 is connected with 7 screw of bottom plate, and the ejector retainner plate 6 is between 3 support block of moving template；It is equipped at the top of the ejector sleeve core 14
The taper head to match is buckled to car light part；The ejector retainner plate 6, which is equipped with, draws material ejector sleeve structure；Ejector sleeve structure packet is expected in the drawing
