Description
Technical field
The present invention relates to injection molds, more particularly to core-pulling mechanism outside injection molding mould fixed die skew back guide post.
Background technique
In some plastic parts, people are very high to the surface requirements of appearance (such as outside the decoration of automobile external, mobile phone
Shell etc.), if being formed with side opening in the side of product, prior art generallys use (as shown in Figure 5) solid plate 1 ' and moving template 2 ',
Inclined guide pillar 3 ' is set in solid plate, side action sliders 4 ' are set on moving template, is provided with oblique guide hole 5 ' in side action sliders, is opening
When mould, cooperated by inclined guide pillar and the oblique guide hole of side action sliders, side action sliders is driven to move extraction plastic part outward
Side opening, the structure have the drawback that: since side action sliders directly are arranged in plastic part side wall, solid plate can not encase completely
The outer wall of plastic part, generates parting line between solid plate and side action sliders, the plastic part outer wall of injection molding is made to be located at cover half
Weld bond after leaving parting at plate and side action sliders, to influence the shape of plastic part, therefore people are by side action sliders
Setting enables solid plate to encase the outer wall of plastic part completely in solid plate side, and drives side action sliders to take out by oil cylinder
On the one hand the side opening of plastic part out improves the manufacturing cost of mold using cylinder structure, on the other hand want before mold die sinking
It drives side action sliders first to carry out core pulling by oil cylinder, could be opened again, reduce the production efficiency of mold.
Summary of the invention
The purpose of the invention is to overcome prior art there are the shortcomings that, providing one kind, to avoid plastic part surface from leaving molten
Wiring guarantees plastic part good appearance, reduces die manufacturing cost, improves outside the injection molding mould fixed die skew back guide post of production efficiency
Core-pulling mechanism.
The technical solution of the outer core-pulling mechanism of injection molding mould fixed die skew back guide post of the present invention is: including upper compound plate and lower compound plate,

There is spring groove, the first spring is set in spring groove, the first spring upper end is in contact with moving template, the lower end of the first spring and backing plate
It is in contact, spacing kerve is formed under backing plate, is provided with through-hole in spacing kerve, spacing blind rivet, spacing are set in spacing kerve
Distance plate is formed under blind rivet, the upper end of spacing blind rivet passes through through-hole and spring groove is connected with moving template.
The invention discloses core-pulling mechanisms outside a kind of injection molding mould fixed die skew back guide post, after plastic part injection molding, under
Compound plate drives support block, upper ejector retainner plate, lower ejector retainner plate, thimble, backing plate, lock module, inclined guide pillar and baffle to move backward, backing plate to
After when moving, the first spring withstands forward moving template under the action of restoring force, protects moving template, spacing blind rivet and plastic part first
Hold it is motionless, make mold first be opened for the first time between backing plate and moving template, when lock module and inclined guide pillar move backward, lock module
Progressively disengage contact side action sliders, and inclined guide pillar and the oblique guide hole of side action sliders cooperate, drive side action sliders gradually to
Outside is mobile, and the convex block of side action sliders is made to extract the side opening of plastic part out outward, when the distance plate and spacing kerve of spacing blind rivet
When being in contact, spacing kerve holds spacing blind rivet, drives spacing blind rivet, moving template and plastic part to move backward together, makes mold
From twice-die-opening from moving template and solid plate, finally drive upper and lower ejector retainner plate and thimble by plastic part top by the mandril of injector
It demoulds out.The outer core-pulling mechanism of this programme injection molding mould fixed die skew back guide post, by being arranged side action sliders in cover half side, and
Inclined guide pillar and spacing blind rivet structure is arranged in dynamic model side, by being opened the side opening of extraction plastic part twice, to avoid plastic part
Surface leaves weld bond, guarantees plastic part good appearance, and save cylinder structure, reduces die manufacturing cost, improves production effect
Rate.
Injection molding mould fixed die skew back guide post of the present invention outer core-pulling mechanism is formed with location hole, location hole in the solid plate
Second spring is arranged in the upper end of middle setting positioning pin, positioning pin, and the upper end of second spring is in contact with upper compound plate, second spring
