Description
Technical field
The invention belongs to the technical fields of material molding die.More particularly it relates to a kind of mold slanted core pulling knot
Structure.
Background technology
Air-conditioning split air conditioner one chassis is needed by being formed together with two product integrations in common chassis and outlet frame
Multiple pulled core structures are designed in one set of die, mould structure is complicated.Wherein at the air duct of chassis, one long circular arc of product design
Convex configuration cannot demould on mold die sinking direction, need oblique core pulling.
For this product, intermediate air duct is that requirement is very high, needs to ensure intermediate air duct both ends injection balance, makes production
Product wall thickness is consistent, it is impossible to be deformed.In the prior art, it is that chassis air passage portion is designed to preceding mould part, air duct director
Arc convex surface need to do a preceding big pulled core structure of mould.
For the oblique core pulling of mould before setting, need to set a driving dynamic structure tiltedly taken out in preceding mould.In the prior art, often
The design of rule is driven with spring or oil cylinder.But above-mentioned design is respectively present problems with：
It is such as driven with spring, there are one hysteresis for spring, it is impossible to which synchronous with die sinking action, tiltedly taking out both ends ejection can not
Balance, the bad phenomenons such as wall unevenness, influence product quality when being molded so as to cause product both ends；
If driven with oil cylinder, mold need to increase lengthening, it is impossible to meet injection molding machine production requirement, and oil cylinder needs
One action cycle lengthens injection time, it is impossible to efficiently production.
Invention content
The present invention provides a kind of mold slanted pulled core structure, and the purpose is under the premise of meeting injection molding machine and efficiently producing, protect
Demonstrate,prove product air duct both ends injection balance, uniform wall thickness.
To achieve these goals, the technical solution taken of the present invention is：
The mold slanted pulled core structure of the present invention, including core pulling, spring；The core pulling is fixed by angle ejector rod and release link
Connection；The release link is oriented to by the guide groove on guide pad；The direction of the guide groove is identical with core pulling direction；Described
Drag hook is set in the rear mold of mold, and the drag hook clasps the buckle side in release link；Under the motion state of die sinking, the drag hook by
Gradually it is detached from buckle side.
The angle ejector rod, release link are two, are separately positioned on the both ends of the core pulling.
Rear mold is set to put up a bridge in the rear mold, the drag hook is fixed in rear mold bridging.
The rear mold bridging is inclined-plane with resetting the part that rod end surface contacts, and the inclined-plane is perpendicular to the longitudinal direction of release link.
Limited block is set on the preceding mould of the mold；At the end of core pulling ejects, on the limited block and release link
Confined planes contact.
It is connected between the core pulling and T shape guide pads by T-slot.
The present invention uses above-mentioned technical proposal, both can guarantee that the injection of product air duct both ends balanced, mould structure steady and smooth,
Product both ends uniform wall thickness, ensure that product quality, and disclosure satisfy that the efficient production of injection molding machine.

Specific embodiment
Below against attached drawing, by the description of the embodiment, making to the specific embodiment of the present invention further details of
Illustrate, those skilled in the art to be helped to have more complete, accurate and deep reason to inventive concept of the invention, technical solution
Solution.
Structure of the present invention as shown in Figure 1, is a kind of mold slanted pulled core structure, including core pulling 1, spring 7.The mold packet
Include A plates 8, B plates 9.As shown in figure 4, product 12 is molded by core pulling 1.
In order to solve the problems, such as of the existing technology and overcome its defect, realize in the premise for meeting injection molding machine and efficiently producing
Under, ensure product air duct both ends injection balance, the goal of the invention of uniform wall thickness, the technical solution that the present invention takes is：
As shown in Figures 1 to 7, mold slanted pulled core structure of the invention, the core pulling 1 pass through angle ejector rod 4 and release link 3
It is fixedly connected；The release link 3 is oriented to by the guide groove on guide pad 2；The direction of the guide groove is identical with core pulling direction；
Drag hook 5 is set in the rear mold of the mold, and the drag hook 5 clasps the buckle side in release link 3；Under the motion state of die sinking,
The drag hook 5 progressively disengages buckle side.
Release link 3 is rigidly connected integral by angle ejector rod 4 and the screw of core pulling 1.Release link 3, angle ejector rod 4 and core pulling 1
Angle to be designed to same angle.Drag hook 5 hooks both sides release link 3.
Buckle side in the release link 3 is a longitudinally disposed groove, the end face of groove, i.e. shape in release link 3
Into buckle side.
The present invention takes above-mentioned technical proposal for defect in the prior art, utilizes drag hook and release link
Buckle side fit structure both can guarantee product air duct both ends injection balance, mould structure steady and smooth, and disclosure satisfy that injection molding machine
Efficiently production.When core pulling starts, mainly by the effect of drag hook, the unevenness of core pulling campaign caused by avoiding the hysteresis of spring
It is even, it ensure that product quality.
The angle ejector rod 4, release link 3 are two, are separately positioned on the both ends of the core pulling 1.Such setting is protected
Uniform force, the moving equilibrium of core pulling 1 are demonstrate,proved.
Rear mold bridging 6 is set in the rear mold, and the drag hook 5 is fixed in rear mold bridging 6.Rear mold bridging 6 is fixed on B
On plate 9.
The present invention is one bridging mechanism of setting, the big pulled core structure of mould before realization in rear mold.One is designed in rear mold bridging
A lifting hook device, hook 5 hook the extended release link 3 in front mold core-pulling both sides.
The parts that the rear mold bridging 6 is contacted with 3 end face of release link are inclined-plane, and the inclined-plane is perpendicular to the vertical of release link 3
To.Such setting so that during die sinking, molding, slip stress of the release link 3 in rear mold bridging 6 is essentially identical.
Limited block 10 is set on the preceding mould of the mold；At the end of core pulling ejects, the limited block 10 is with resetting
Confined planes contact on bar 3.The structure of the confined planes is：One groove is set in release link 3, and the end face of groove is
Form confined planes.
It is connected between the core pulling 1 and T shapes guide pad 11 by T-slot.
The course of work of the present invention is as follows：
Mold molds：
A plates 8, the movement of 9 relative separation of B plates, hook release link 3 by drag hook 5, core pulling 1 are driven to move down, meanwhile, spring 7
Start to act, head on angle ejector rod 4 and move down.Meanwhile release link 3 is slided on the inclined-plane of rear mold bridging 6, in release link 3
Buckle side gradually leaves drag hook 5, and after molding a distance, drag hook 5 completely disengages out the buckle side of release link 3, continues to head on by spring 7
Core pulling 1 moves down.It is limited by limited block 10, after reaching ejection stroke distance, angle ejector rod 4 just completes side core-pulling action.Most
Demoulding is completed eventually.
Mold clamping：
When A plates 8, B plates 9 mold, the inclined-plane in bridging mechanism heads on 3 end face of release link, and core pulling 1 is driven to reset, is completed
Molding.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that present invention specific implementation is not by aforesaid way
Limitation, as long as employ the inventive concept and technical scheme of the present invention progress various unsubstantialities improvement or without changing
Other occasions are directly applied to by the design of the present invention and technical solution, within protection scope of the present invention.
