Description
Technical Field
The utility model relates to the technical field of dies, in particular to an oblique back-off demoulding die.
Background
Injection molding and demolding are the last link in the injection molding process. After the injection molding operation is finished, the molded part is cooled and shaped in the mold, and when the molded part is ejected from the mold, friction force generated by demolding resistance must be overcome.
In injection molded articles having a complicated structure, a back-off is usually provided, and the back-off has a structure such as a flange or a hook which is engaged with a mold, so that the mold cannot be released directly, and it is often necessary to release the mold by a special back-off release mechanism. The existing back-off demoulding mechanism is complex in structure, large in occupied space and inconvenient to back-off demoulding.
Compared with the prior art, the injection mold back-off demolding mechanism has the beneficial effects that when in demolding, the sliding block slides to drive the whole slide to horizontally slide, the back-off of a plastic product is separated from the connecting block, meanwhile, after the slide is removed, part of compressive stress is released, then, the oblique jacking moves obliquely upwards to jack up the plastic product, and the back-off demolding is easier due to the fact that the compressive stress is reduced, so that the quality of the plastic product is more perfect, but through researching the patent and the prior art, the applicant considers that the existing oblique back-off demolding mold has the problem of low demolding efficiency, and then the utility model proposes the oblique back-off demolding mold.
