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 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 the plastic product, this moment is when die sinking, plastic product just clings slide block easily, causes the product can not die sinking, even pulls product.
For addressing the above problem, directly installation department tin ejects the post hole with slide block and is difficult to realize in slide block, 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 the latch segment, Angle Pin tilts to pass slide block, described thimble is arranged on the slide block on next door, post hole, but adopt the mode that realizes the demoulding of product at two thimbles of the next door in post hole design, reliability is relatively poor, and because place, post hole unbalance stress, white phenomenon (being that thimble institute top part shows 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 the latch segment, Angle Pin tilts to pass slide block, the right flank of described latch segment is an inclined plane, and the lower end and the latch segment of described slide block are adjacent to, and the upper end of slide block is adjacent to the right flank of latch segment mutually by wear-resistant block.
Described ejector sleeve ejecting structure also comprises department's tube, pin, jacking block, be provided with department's tube installing hole in the middle of the described slide block, described department tube passes the department's tube installing hole in the slide block and withstands product post hole, also be with spring in the department tube outside, described pin places in the middle of department's tube, 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, because the effect of 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 the reliability height has prevented to pull the white phenomenon of plastic product and top effectively.
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, helps wear-resistant block like this it is compressed.

The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
Ejector sleeve ejecting structure in the plastic mould slide block of the present invention, comprise Angle Pin 1, latch segment 2, slide block 3, described Angle Pin 1 tilts to be fixed in the latch segment 2, Angle Pin 1 tilts to pass slide block 3, the right flank of described latch segment 2 is an inclined plane, the lower end of described slide block 3 and latch segment 2 are adjacent to, and the upper end of slide block 3 is adjacent to mutually by the right flank of wear-resistant block 4 with latch segment 2.
Described ejector sleeve ejecting structure also comprises department's tube 5, pin 6, jacking block 7, be provided with department's tube installing hole 8 in the middle of the described slide block 3, described department tube 5 passes the department's tube installing hole 8 in the slide block 3 and withstands product post hole 9, also be with spring 10 in department tube 5 outsides, described pin 6 places in the middle of department's tube 5, and push down by wear-resistant block 4, the right flank of described latch segment 2 is provided with a vertical sliding surface 11, the right-hand member of described jacking block 7 is inserted in the middle of pin 6 afterbodys, the left end of jacking block 7 passes wear-resistant block 4 and withstands the vertical sliding surface 11 of latch segment 2: the afterbody of described pin 6 is an inclined plane, its inclination angle equals the inclination angle on the inclined plane of slide block 3 upper ends, helps wear-resistant block 4 like this it is compressed.
Operation principle of the present invention: during die sinking, slide block 3 moves downward, because the effect of Angle Pin 1, slide block 3 is also pasting the side of latch segment 2 to left movement when moving downward, and jacking block 7 moves downward along the vertical sliding surface 11 of latch segment 2, this moment, latch segment 2 will be given 7 one lasting thrusts of jacking block, made product post hole 9 realize the demoulding thereby jacking block 7 just promotes pin 6.
Below only just preferred embodiment of the present invention be described, but can not be interpreted as it is restriction to claim.The present invention not only is confined to above embodiment, and its concrete structure allows variation, as: the outer shape of department's tube 5, pin 6, jacking block 7 can change, as: cylindrical, square.In a word, all various variations of being done in the protection domain of independent claims of the present invention are all in protection scope of the present invention.
