Description
Technical field
This utility model relates to mould structure field, particularly relates to the secondary ejecting mechanism of a kind of injection mold.
Background technology
Injection mold general only one of which power resources, and the space of mould is extremely limited, drives the driving of ejector retainner plate
The most only one, axle.In injection mold, product is plastics, and when shaping, product can shrink disengaging front mould, and
Often tighten up in rear mold.For the ease of the demoulding, it is therefore desirable to product is carried out Double-ejection.Described Double-ejection, just
It is that ejector retainner plate moves at twice when mould die sinking ejecting product, thus arrival is easy to product and is come off from mould.
In order to realize Double-ejection, the existing general deduction standard component using DME company of the U.S., but due to this standard component
Designing small and exquisite, for reducing volume, it is the weakest that all positions are all designed, and causes rigidity inadequate.The relatively big or top at mould
Go out dynamics relatively big in the case of, certain elastic deformation can be produced, when causing ejecting, synchronization accuracy is the highest.More very can be because of top
Go out stress to damage, affect the stability of mould.Further, this standard component is expensive, and need to design at mould inside,
Certain space need to be taken, the spatial arrangements of mould inside is designed with certain difficulty.
Utility model content
In order to solve above-mentioned technical problem, this utility model provides the secondary ejecting mechanism of a kind of injection mold.This reality
By novel secondary ejecting mechanism simple in construction, the structural strength of mechanism part is high, and mechanism is installed on mold exterior,
It is not required to take inner space, arranges more flexible.
Concrete technical scheme of the present utility model is: the secondary ejecting mechanism of a kind of injection mold, including framework, first
Ejector retainner plate group, the second ejector retainner plate group, drive shaft, top cover set, hook and flexible screens parts.
Described framework is the cavity being provided with up/down perforation in cubic type and framework, described first ejector retainner plate group, the second top
It is interior and parallel to each other that needle plate group is the most vertically located at described cavity；Described drive shaft be arranged in framework, first
One end of ejector retainner plate group and the second ejector retainner plate group and drive shaft is fixed in the second ejector retainner plate group；Described first ejector retainner plate group
Top end face be provided with groove, described flexible screens parts are located in described groove and flexible screens parts are collapsible or stretch
For in groove；Described hook is positioned at the first ejector retainner plate group and the top end face of the second ejector retainner plate group and the right-hand member of hook and
Two ejector retainner plate group top end faces are fixing to be connected, and described hook lower surface, corresponding to being provided with slot at flexible screens parts, is stretched
Contracting screens parts can be sticked in described slot when stretching out in groove；Described top cover set covers at above framework and hook,
The right-hand member lower surface of top cover set is fixing with frame upper surface to be connected, corresponding to being provided with at flexible screens parts bottom top cover set
Breach, flexible screens parts can be sticked in described breach when stretching out in groove.
As preferably, described flexible screens parts include key and the return spring being vertically arranged, on described return spring
Bottom with described key and described groove respectively, lower two ends is connected, the length of described key more than the width of described hook,
Key can engage with described slot and breach respectively.
As preferably, described key with at the engaging of described breach be the hypotenuse declined the most from left to right, described breach
Be provided with chamfering at the engaging of key.
As preferably, described top cover set is corresponding to being provided with groove at described hook upper surface, described hook activity is embedded at
In described groove.
As preferably, the quantity of described return spring is two.
Operation principle of the present utility model is:
Under the promotion to the right of drive shaft, be connected owing to the second ejector retainner plate group and drive shaft are fixing, the second ejector retainner plate group to
Right displacement.Meanwhile, under initial condition, flexible screens parts stretch out in groove, engage with the slot of hook,
First ejector retainner plate group displacement the most to the right.After drive shaft arrives certain stroke, the right side of flexible screens parts and top cover set
Breach conflict, along with the continuous driving of drive shaft, flexible screens parts by the active force of top cover set indentation, there,
Pressurized retracted downward, is gradually retracted in groove, and the screens parts that i.e. stretch depart from hook, therefore the first ejector retainner plate group
Lack driving force, the most to the right displacement, and the second ejector retainner plate group has continued displacement one end stroke, until product stripping.
Being compared with the prior art, the beneficial effects of the utility model are:
The all workpiece of this utility model structure are made by oneself, and it is simpler that structure compares DME standard component.All parts can be according to reality
Border needs design, and mould is relatively big or ejects and with stronger dynamics just corresponding component design is strengthened.And mechanism installation
In mold exterior, it is not required to take inner space, arranges more flexible.
