Description
Technical field
The utility model relates to a kind of product with back-off and uses mould structure.
Background technology
At present, in the mould molding industry, for the band back-off product generally adopt first moulding, after utilize CNC processing place back-off.Adopt CNC processing, not only cost of idleness, and the product surface after the processing plays husky hole easily, has reduced yield.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of product with back-off to use mould structure, and this mould structure is simple, can make the product one-shot forming of band back-off, and needn't process by CNC, reduces cost, and promotes yield.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of product with back-off is used mould structure; Comprise front template, rear pattern plate and be located at this front template respectively and rear pattern plate in the front mould Renhe after die; Die forms recess corresponding to the lateral surface of said product to be formed before said; Said back die forms protuberance corresponding to the medial surface of said product to be formed; The die closure lumps together said protuberance and sets of recesses and forms the die cavity consistent with shape of product to be formed behind the said front mould Renhe; In the die of said back, also be provided with oblique ejection device; This oblique ejection device comprises that fixed mount is located at the oblique fore-set of two on this fixed mount with movable, and said fixed mount is fixedly arranged on the said rear pattern plate, and said two oblique fore-sets pass said back die and its end is exposed the protuberance on the said die afterwards respectively; But and have an acute angle angle and move toward one another between the other end of two oblique fore-sets, on the end face of two oblique fore-sets, be respectively equipped with the protuberance consistent in addition with the back-off shape of said product to be formed.During moulding, tiltedly two oblique fore-sets on the ejection device and front and back die cooperate formation and the on all four die cavity of product to be formed just, like this; Can make product and on the back-off straight forming, remove front template and front mould die then, utilize liftout attachment and oblique ejection device to eject product together again; Eject in the process at product, tiltedly two oblique fore-sets on the ejection device since between have an acute angle angle, the other end its fixed mount slip relatively simultaneously; Therefore an end of two oblique fore-sets is in ejecting the product process, and the two is also each other near moving, like this; Can deviate from product smoothly, not have moulding thereby exempt the product back-off, and need the process of follow-up CNC processing; Reduce production process, reduction manufactures a finished product, and improves the product yield.
Further improvement as the utility model; The fixed mount protection square block of said oblique ejection device and fixing and parallel two pillars that are set in this square block; One end of said two oblique fore-sets is movable respectively to be located in the end of this two pillar, and the other end of two oblique fore-sets can do mutual near with away from motion.
Further improvement as the utility model; One end of said two oblique fore-sets is movable respectively to be located in the end of this two pillar; And the other end of two oblique fore-sets can do each other near with away from the structure of motion be: in an end of said two pillars, be respectively equipped with groove; The cross-sectional sizes of this groove on the end face of two pillars is just identical with the cross-sectional sizes of said two oblique fore-sets, and this bottom portion of groove has than its area of section big on the pillar end face.Like this, an end of two oblique fore-sets is movable at bottom portion of groove, thus make the two oblique fore-set other ends do mutual near with away from motion.
The beneficial effect of the utility model is: through adopting oblique ejection device, make back-off and the product moulding simultaneously of product, and during the demoulding; Utilize the structure of oblique ejection device; Again can be conveniently stripped, and can not cause damage to product, this structure is not only simple to operate; And can reduce cost, improve the product yield.
