Abstract
The invention discloses an ejector sleeve ejecting structure in a plastic mould slide block. The ejector sleeve ejecting structure comprises an inclined guide column (1), a locking block (2), the slide block (3), an ejector sleeve (5), an insert pin (6) and a jacking block (7), wherein an ejector sleeve mounting hole (8) is formed in the slide block (3); the ejector sleeve (5) passes through the ejector sleeve mounting hole (8) in the slide block (3) and is pressed against a product column hole (9), and the outer side of the ejector sleeve (5) is also sleeved with a spring (10); the insert pin (6) is arranged in the ejector sleeve and pressed by a wear plate (4); the right side surface of the locking block (2) is provided with a vertical sliding surface (11); and the right end of the jacking block (7) is sleeved into the tail part of the insert pin (6), and the left end of the jacking block (7) passes through the wear plate block (4) and is pressed against the vertical sliding surface of the locking block. The ejector sleeve ejecting structure has the advantages of effectively avoiding the strain of a plastic product and an ejector mark, along with good demolding effect and high reliability.
Description
Technical field
The present invention relates to the mould of plastics field, is the ejector sleeve ejecting structure in a kind of plastic mould slide block specifically.
Background technology
In the manufacture process of mould of plastics, many times product has back-off (stripping direction of this position and die sinking direction are inconsistent) in the cover half direction, can not the demoulding, need to make slide block could the demoulding, and the rib of the plastic product of making when needs is many when deep, and darker post hole is especially arranged on plastic product, this moment is when die sinking, plastic product just easily clings slide block, causes the product can not die sinking, even pulls product.
for addressing the above problem, ejector sleeve directly is installed in slide block to be ejected the post hole with slide block and is difficult to realize, the demoulding ejecting structure at the place, post hole of prior art comprises Angle Pin, latch segment, slide block, thimble, described Angle Pin is fixed in latch segment, Angle Pin tilts to pass slide block, described thimble is arranged on the slide block on side, post hole, but employing designs on the side in post hole the mode that two thimbles are realized the demoulding of product, reliability is relatively poor, and due to place, post hole unbalance stress, white phenomenon (be thimble institute top part show as white) can appear pushing up in product, so stripping result is unsatisfactory.
Summary of the invention
The technical problem to be solved in the present invention is that the ejector sleeve ejecting structure in the good plastic mould slide block of a kind of stripping result is provided.
Technical solution of the present invention is, ejector sleeve ejecting structure in a kind of plastic mould slide block of following structure is provided, comprise Angle Pin, latch segment, slide block, described Angle Pin tilts to be fixed in latch segment, Angle Pin tilts to pass slide block, the right flank of described latch segment is an inclined plane, and lower end and the latch segment of described slide block are adjacent to, and the upper end of slide block is adjacent to mutually by the right flank of wear-resistant block with latch segment.
Described ejector sleeve ejecting structure also comprises ejector sleeve, pin, jacking block, be provided with the ejector sleeve installing hole in the middle of described slide block, described ejector sleeve is passed the ejector sleeve installing hole in slide block and is withstood product post hole, also cover has spring outside ejector sleeve, described pin is placed in the middle of ejector sleeve, and is pushed down by wear-resistant block, and the right flank of described latch segment is provided with a vertical sliding surface, the right-hand member of described jacking block is inserted in the middle of the pin afterbody, and the left end of jacking block passes wear-resistant block and withstands the vertical sliding surface of latch segment.
Adopt above structure, the present invention compared with prior art has the following advantages: adopt structure of the present invention, during die sinking, slide block moves downward, effect due to Angle Pin, slide block is simultaneously also to left movement, so jacking block moves downward along the vertical sliding surface of latch segment, this moment, latch segment will be given lasting thrust of jacking block, thereby jacking block just promotes pin and realizes the demoulding, its stripping result is good, and reliability is high, has effectively prevented from pulling the white phenomenon of plastic product and top.
As improvement, the afterbody of described pin is an inclined plane, and its inclination angle equals the inclination angle on the inclined plane of upper end of slide block, is conducive to like this wear-resistant block it is compressed.
