Description
Technical field
The utility model relates to injection mould pulled core structure, particularly relates to a kind of cavity core pulling retreating prevention mechanism.
Background technology
Injection mold is a kind of instrument producing plasthetics, by the material melted that is heated is injected die cavity by high pressure, after cooling curing, obtains formed products.Some is recessed or side opening ground plastic products with side, first must carry out undercut being pushed out before, can the demoulding smoothly after extraction side core_pulling, now need to arrange side core-pulling mechanism in a mold.
Adopt oil cylinder to drive during cover half side core-pulling, will pressure be produced when mold injection in needle section of loosing core.Can retreat owing to being subject to injection pressure pin of loosing core in production process, and then cause product defective.And because be cover half side core-pulling, so common latch segment can not be increased.
Utility model content
Technical problem to be solved in the utility model is exactly for above shortcomings in prior art, provides a kind of cavity core pulling retreating prevention mechanism, for solving the problems of the prior art.
For achieving the above object and other relevant objects, the utility model provides a kind of cavity core pulling retreating prevention mechanism, comprising:
Contiguous block, the front and back ends of described contiguous block connects latch segment respectively, loose core pin fixed bar and oil cylinder;
Be provided with below latch segment and lock small slide block, described latch segment bottom surface is provided with T-shaped slide block, described in lock small slide block top and be provided with T-shaped chute, described latch segment by described T-shaped slide block, sliding groove structure along described in lock small slide block end face and slide;
Lock pin fixed bar of loosing core described in arranging below small slide block, described in lock bottom small slide block and be provided with retaining plate, pin fixed bar of loosing core is provided with back stop slot;
During matched moulds, oil cylinder pushing contiguous block travel forward drive latch segment along described in lock small slide block end face and slide, during stroke end, latch segment with lock small slide block and be separated, lock small slide block and move downward, retaining plate inserts in described back stop slot.
Further, described latch segment and the contact surface locking small slide block are inclined-plane from high to low from front to back.
Further, described in lock the profiling open slot being provided with pin fixed bar of loosing core bottom small slide block and form two pieces of retaining plates be oppositely arranged, described in pin fixed bar both sides correspondence of loosing core two back stop slots are set.
By above technical scheme, the utility model has following technique effect compared to prior art: during matched moulds, under the promotion of oil cylinder, whole mechanism travels forward, latch segment slides into be separated along locking small slide block end face with it, lock the retaining plate arranged bottom small slide block to slip into and block pin fixed bar of loosing core in the back stop slot of loosing core on pin fixed bar and retreat, thus block injection pressure, do not allow oil cylinder go all to bear injection pressure, prevent the rollback of loosing core, improve product defects.

Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar the content disclosed by this description can understand other advantages of the present utility model and effect easily.
Refer to Fig. 1 to Fig. 4.Notice, structure, ratio, size etc. that this description institute accompanying drawings illustrates, content all only in order to coordinate description to disclose, understand for person skilled in the art scholar and read, and be not used to limit the enforceable qualifications of the utility model, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the utility model can produce and the object that can reach, still all should drop on technology contents that the utility model discloses and obtain in the scope that can contain.Simultaneously, quote in this description as " on ", D score, "left", "right", " centre " and " one " etc. term, also only for ease of understanding of describing, and be not used to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under changing technology contents without essence, when being also considered as the enforceable category of the utility model.
Consult shown in Fig. 1, be shown as the structural representation of the utility model cavity core pulling retreating prevention mechanism, comprise:
Contiguous block 10, the front and back ends of contiguous block 10 connects latch segment 9 respectively, loose core pin fixed bar 2 and oil cylinder 8, and pin 1 of loosing core is installed in pin fixed bar front end of loosing core.
Be provided with below latch segment 9 and lock small slide block 3, latch segment 9 bottom surface is provided with T-shaped slide block (shown in Fig. 3), lock small slide block 3 top and be provided with T-shaped chute (shown in Fig. 2), latch segment 9 is slided along locking small slide block 3 end face by T-shaped slide block, sliding groove structure;
Lock below small slide block 3 and pin fixed bar 2 of loosing core is set, lock the profiling open slot Structure composing two pieces of retaining plates be oppositely arranged being provided with pin fixed bar of loosing core bottom small slide block 3, pin fixed bar both sides correspondence of loosing core arranges two back stop slots (shown in Fig. 4).
During matched moulds, oil cylinder is acted on contiguous block 10 by oil cylinder connecting rod 6, promotes whole mechanism and travels forward.Under the effect of spring 4 and limited screw 5 of loosing core, pin fixed bar 2 of loosing core first puts in place stop motion (other continues motion) again.Oil cylinder pushing contiguous block travel forward drive latch segment along described in lock small slide block end face and slide, during stroke end, latch segment 9 with lock small slide block 3 and be separated, lock small slide block 3 and move downward, retaining plate inserts in described back stop slot.First extract out during die sinking and lock small slide block and extract out together again.
As further improvement of the utility model, latch segment 9 and the contact surface locking small slide block 3 are inclined-plane from high to low from front to back.
Above-described embodiment is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model.Any person skilled in the art scholar all without prejudice under spirit of the present utility model and category, can modify above-described embodiment or changes.Therefore, such as have in art and usually know that the knowledgeable modifies or changes not departing from all equivalences completed under the spirit and technological thought that the utility model discloses, must be contained by claim of the present utility model.
