Abstract
The utility model discloses a slide rotary pulling-out structure applied to an injection mould, which comprises a slide block with an inner cavity, wherein the rear parts of an upper pull rod and a lower pull rod stretch into the inner cavity of the slide block and are elastically connected with the slide block through springs; upper strip-shaped holes and lower strip-shaped holes which correspond to one another are arranged at the rear part of the upper pull rod, the rear part of the lower pull rod and on the top surface of the slide block; the upper strip-shaped holes are shorter than the lower strip-shaped holes; an upper limiting needle and a lower limiting needle which are arranged on the bottom surface of the inner cavity of the slide block respectively penetrate through the upper strip-shaped holes and the lower strip-shaped holes to movably limit the upper pull rod and the lower pull rod in the upper strip-shaped holes and the lower strip-shaped holes; a rotary inlaying piece is arranged at the front end of the slide block, an upper limiting groove and a lower limiting groove are respectively arranged at the rear ends of the rotary inlaying piece, the front end and the rear end of a connecting rod are respectively and movably connected with the upper limiting groove and the upper pull rod of the rotary inlaying piece through pins, and the lower pull rod is movably connected with the lower limiting groove of the rotary inlaying piece through the pin. The slide rotary pulling-out structure is simple and reasonable, solves the problem that the demoulding of an irregularly-shaped shell body with an inverted hook at the inner part is difficult and can be widely applied to the injection mould.
Description
Technical field
The utility model relates to a kind of injection mold, and structure is extracted in particularly a kind of row position rotation that is applied to injection mold out.
Background technology
For the housing of some injection mo(u)ldings, portion can design back-off within it according to demand, because the housing global shape is irregular, make this constructed products depanning difficult, can't for the ease of this constructed products depanning, be necessary the structure of mould is designed by row position depanning at ordinary times.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of row position rotation rational in infrastructure, that depanning is applied to injection mold easily to extract structure out.
The technical scheme that its technical problem that solves the utility model adopts is:
Structure is extracted in the row position rotation that is applied to injection mold out, the row position piece that comprises the band inner chamber, on having, lower link stretches to the rear portion in the piece inner chamber of row position, and be connected with row position piece elasticity by spring, be positioned at, on lower link rear portion and row position piece end face are provided with accordingly, following bar hole, it is shorter than following bar hole wherein to go up bar hole, piece inner chamber bottom surface, described row position is provided with, the lower limit pin, on described, the lower limit pin passes respectively, following bar hole will be gone up, lower link is movable spacing last respectively, in the following bar hole, be positioned at row position piece front end and be provided with the rotation mold insert, be respectively equipped with in rotation mold insert rear end, the lower limit groove, have connecting rod that the rear and front end is flexibly connected with upper limit position groove that rotates mold insert and upper connecting rod respectively by pin, described lower link flexibly connects by the lower limit groove of pin with the rotation mold insert.
The beneficial effects of the utility model are: in the product stripping process, row position piece withdraws from backwards, because last bar hole is shorter than following bar hole, the upper limit pin that is arranged in bar hole retinue position piece fallback procedures earlier by on the pulling of bar hole front end face, make upper connecting rod drivening rod and rotation mold insert top turn an angle, to break away from the back-off in the product; Simultaneously, row position piece continues stressed retreating, when the bar hole front end face is run into the lower limit pin instantly, the pulling lower link also simultaneously will rotate mold insert in the lump with upper connecting rod and deviate from from product, finish the product stripping process, the utility model is simple and reasonable, has solved the problem of the irregularly shaped housing demoulding difficulty of inner band overhead kick.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation after the utility model demoulding.
The specific embodiment
With reference to Fig. 1, Fig. 2, structure is extracted in the row position rotation that is applied to injection mold out, the row position piece 1 that comprises the band inner chamber, on having, lower link 4,5 stretch to the rear portion in piece 1 inner chamber of row position, and be connected with row piece 1 elasticity by spring 12, be positioned at, lower link 4, on 5 rear portions and row position piece 1 end face are provided with accordingly, following bar hole 2,3, wherein go up bar hole 2 than following bar hole 3 weak points, piece 1 inner chamber bottom surface, described row position is provided with, lower limit pin 6,7, on described, lower limit pin 6,7 pass respectively, following bar hole 2,3 will go up, lower link 4,5 is movable spacing last respectively, following bar hole 2, in 3, be positioned at row position piece 1 front end and be provided with rotation mold insert 8, be respectively equipped with in rotation mold insert 8 rear ends, lower limit groove 9,10, have connecting rod 11 that the rear and front end is flexibly connected with upper limit position groove 9 that rotates mold insert 8 and upper connecting rod 4 respectively by pin, described lower link 5 flexibly connects by the lower limit groove 10 of pin with rotation mold insert 8.
In the product stripping process, row position piece 1 withdraws from backwards, because last bar hole 2 is than following bar hole 3 weak points, the upper limit pin 6 that is arranged in bar hole 2 retinue position piece 1 fallback procedures earlier by on the pulling of bar hole 2 front end faces, make upper connecting rod 4 drivening rods 11 and rotation mold insert 8 tops turn an angle, to break away from the back-off in the product 20; Simultaneously, row position piece 1 continues stressed retreating, and when bar hole 3 front end faces are run into lower limit pin 7 instantly, pulling lower link 7 also will rotate mold insert 8 in the lump with upper connecting rod 6 simultaneously and deviate from from product, finish the product stripping process; When closing film, by row position 15 reaction forces rotation mold insert 8, all part resets, and the effect of spring 12 mainly is to prevent that upper and lower pull bar 4,5 from retreating in the die sinking process voluntarily.The utility model is simple and reasonable, has solved the problem of the irregularly shaped housing demoulding difficulty of inner band overhead kick, is that structure is extracted in a kind of row position rotation that is widely used in injection mold out.
