Abstract
The utility model discloses an ejector sleeve ejection structure in a plastic mould sliding block, which comprises an inclined guide post (1), a locking block (2) and a sliding block (3), and also comprises an ejector sleeve (5), an insert pin (6) and an ejection block (7), wherein the sliding block (3) is internally provided with an ejector sleeve mounting hole (8); the ejector sleeve (5) passes through the ejector sleeve mounting hole (8) in the sliding block (3) and props against a product post hole (9); 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 is pressed by a wear-resisting block (4); the right side of the locking block (2) is provided with a vertical sliding surface (11); the right end of the ejection block (7) is sleeved in the tail of the insert pin (6), and the right end of the ejection block (7) passes through the wear-resisting block (4) and then props against the vertical sliding surface of the locking block. With the structure, the utility model has good demoulding effect and high reliability, and effectively prevents the scratching of the plastic product and ejection mark.
Description
Technical field
The utility model 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.
The utility model content
The technical problems to be solved in the utility model 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 utility model 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 utility model compared with prior art has the following advantages: adopt the utility model structure, 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 utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Ejector sleeve ejecting structure in the plastic mould slide block of the present utility model, 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, and 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, and 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 utility model: 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 be described, but can not be interpreted as it is restriction claim with regard to the utility model preferred embodiment.The utility model 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 the utility model independent claims are all in protection domain of the present utility model.
