Abstract
The utility model discloses a mechanism for pulling the core by backing off the external edge of a injection mold, which comprises a back-off embedding element, an inclined guiding post, a top disc bracket component, a shore blocking plate, a thimble, a thimble plate, a pushing plate and a movable die cavity, and is characterized in that the inclined guiding post is fixed with the back-off embedding element in the way of forming a given oblique angle with the mold opening direction, and the movable die cavity is provided with a corresponding sliding groove, and the inclined guiding post is connected with the movable die cavity in a sliding way. The removable of the work piece is performed through the cooperation of the inclined guiding post and the integral top disc bracket component, thereby resolving the 15 degrees limit problem of the inclined mandrill in the prior art, and simplifying the mold structure, and reducing the mold cost.
Description
Technical field
The present invention relates to a kind of core-pulling mechanism, refer in particular to a kind of outside border back-off core-pulling mechanism that is used for injection mold.
Background technology
In the plastic products mould of the outside border of existence of circumferential back-off, the common dropout mode of outside border back-off is that the back-off mold insert is divided into four of quadrant, four angle ejector rods are installed on ejector retainner plate, when evading material before the ejector retainner plate, four angle ejector rods promote four back-off mold inserts simultaneously forward, toward outer displacement, realize border back-off dropout, workpiece is finished under the promotion of other thimbles and is taken off material simultaneously.The angle ejector rod of this structure is stressed big, is difficult to finish reliably oblique top dropout operation when surpassing 13 ° at the angle ejector rod inclination angle, and die cost is higher simultaneously.
Summary of the invention
The objective of the invention is to solve above-mentioned prior art problems, a kind of simple in structure, dependable performance is provided, can effectively reduces the outside border back-off core-pulling mechanism that is used for injection mold of die manufacturing cost.
The present invention is achieved in that
A kind of outside border back-off core-pulling mechanism that is used for injection mold, comprise back-off mold insert, Angle Pin, take over a business blade assemblies, fore-set clamp, thimble, ejector retainner plate, push pedal and dynamic model die cavity, described Angle Pin becomes ground, certain angle of inclination to fix with the back-off mold insert with the die sinking direction, the dynamic model die cavity is provided with corresponding chute, and Angle Pin slidably is connected with the dynamic model die cavity.
Describedly take over a business blade assemblies and comprise fore-set, take over a business, take over a business supporting plate, take over a business blade assemblies and be installed on the ejector retainner plate by the fore-set clamp, fore-set is fixed with screw rod, and push pedal is provided with can be for the hole of screw rod slip, take over a business and take over a business supporting plate and all fix, describedly take over a business supporting plate and be provided with flange with fore-set.
The inclination angle of described Angle Pin can be made as 0 ° ~ 25 °.
Described dynamic model die cavity is provided with the clamp release pin, is equipped with the hole that can supply the clamp release pin to pass through in fore-set clamp, the push pedal, and the hole of fore-set clamp and the hole of push pedal are eccentric installs.
Be provided with spring between described fore-set clamp and the ejector retainner plate.
The outside border of the present invention back-off mold insert is divided into the circumference quarter, carry out the material work of taking off of workpiece by adopting Angle Pin and the whole cooperation of taking over a business blade assemblies, thereby solved the restricted problem of 15 ° of angle ejector rods in the prior art, simplified mould structure, reduced the cost of mould.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
For being illustrated more clearly in technical scheme of the present invention, the present invention is further described below in conjunction with embodiment.
As shown in Figure 1, a kind of outside border back-off core-pulling mechanism that is used for injection mold, comprise back-off mold insert 5, Angle Pin 6, take over a business blade assemblies 2, fore-set clamp 8, thimble 1, ejector retainner plate 10, push pedal 11 and dynamic model die cavity 4, described Angle Pin 6 becomes ground, certain angle of inclination fixing with back-off mold insert 1 with the die sinking direction, dynamic model die cavity 4 is provided with corresponding chute 401, and Angle Pin 6 slidably is connected with dynamic model die cavity 4.
As shown in Figure 1, describedly take over a business blade assemblies 2 and comprise fore-set 203, take over a business 201, take over a business supporting plate 202, taking over a business blade assemblies 2 is installed on the ejector retainner plate 10 by fore-set clamp 8, fore-set 203 is fixed with screw rod 12, push pedal 11 is provided with can be for the hole of screw rod 12 slips, take over a business 201 and all fix, describedly take over a business supporting plate 202 and be provided with flange 204 with fore-set 203 with taking over a business supporting plate 202.
As shown in Figure 1, the inclination angle of described Angle Pin 6 can be made as 0 °～25 °.
As shown in Figure 1, described dynamic model die cavity 4 is provided with clamp release pin 7, is equipped with the hole that can supply clamp release pin 7 to pass through in fore-set clamp 8, the push pedal 11, and the hole of fore-set clamp and the hole of push pedal are eccentric installs.
As shown in Figure 1, be provided with spring 9 between described fore-set clamp 8 and the ejector retainner plate 10.
As shown in Figure 1, after mould is finished injection moulding, push pedal 11 promotes ejector retainner plate 10 and moves forward, take over a business blade assemblies 2 and thimble 1 and promote workpiece 3 beginning demoulding actions, back-off mold insert 5 is under the constraint of promotion of taking over a business supporting plate 202 and Angle Pin 6, not only produced to vertically move but also produce laterally to thread off and moved, when back-off mold insert 5 and workpiece 3 are threaded off fully, clamp release pin 7 just in time contacts with the hole of fore-set clamp 8, the elastic force that clamp release pin 7 overcomes spring 9 enters the hole of fore-set clamp 8, make the hole of hole and push pedal 11 of fore-set clamp 8 gradually become concentric by off-centre, make fore-set clamp 8 break away from promotion to fore-set 203, push pedal 11 and ejector retainner plate 10 continues reach, only promotes thimble 1 and finishes the final material action of taking off.
The foregoing description is to further specify of the present invention, is not to concrete qualification of the present invention, therefore does the variation that is equal to according to the present patent application claim, is the scope that contains in the present invention.
