Description
Technical field
The utility model relates to mould of plastics field, and one ejects oblique core-drawing demoulding mechanism three times specifically.
Background technology
General injection mold interiors of products does not have back-off structure, can directly adopt dome pin, jacking block or ejecting push plate.When injection mold interiors of products has back-off structure; the oblique top that will be designed to oblique movement realizes repeatedly ejecting; in safe automobile air bag injection mold; because plastic products button bit is distributed in interiors of products; common product inner space size is not enough to common lifter demoulding mechanism of arranging; and having again the interference of explosion tear line, goods cannot disposablely eject.As goods button bit is positioned at product inner bottom part, high low head is large, interior tendon position is more, the outside glue position of product cannot eject with internal sizes position simultaneously, the quality of products appearance cannot be ensured, according to pulling mechanism in common because inner space its intensity limited can be had a greatly reduced quality, goods easily rupture, and the maintenance cost of mould is high.
Utility model content
The technical problems to be solved in the utility model is to provide and a kind of ejects oblique core-drawing demoulding mechanism three times, and the slip that can realize after ejecting at three times tiltedly loosing core ejects, thus ensures that product can the demoulding smoothly.
The technical solution adopted in the utility model is: one ejects oblique core-drawing demoulding mechanism three times, comprise cover half fixed head, cover half die cavity, cover half mold insert, dynamic mould fixing plate, dynamic model die cavity, it is characterized in that, described cover half die cavity is equipped with cover half fixed head, described cover half mold insert is fixed in cover half die cavity, dynamic mould fixing plate is equipped with mould pin, thimble lower plate, described dynamic model die cavity is fixed on dynamic mould fixing plate by crura membranacea, dynamic model die cavity is built with insert, tiltedly loose core and interior straight jacking block, described thimble lower plate is fixed with straight top and oblique top, straight top is fixed on thimble upper plate, guide post of loosing core to be fixed in thimble on plate.
Further; described one ejects oblique core-drawing demoulding mechanism three times; it is characterized in that dynamic mould fixing plate being provided with oil cylinder fixed cover; oil cylinder fixed cover is connected with and ejects return oil cylinder; eject return oil cylinder and can drive plate in thimble lower plate, thimble upper plate, thimble; lower roof plate, toward the motion of goods depanning direction, provides power for mechanism resets simultaneously.
Further, described one ejects oblique core-drawing demoulding mechanism three times, it is characterized in that being provided with oblique top groove and straight inverted draw cut in insert, plays the effect of fixing straight top and oblique top.
Further, one ejects oblique core-drawing demoulding mechanism three times, it is characterized in that described interior straight jacking block is provided with gathering sill, tiltedly looses core and mutually can be cascaded by gathering sill and straight jacking block.
Further, described one ejects oblique core-drawing demoulding mechanism three times, it is characterized in that described tiltedly loosing core is provided with stopper slot, and guide post of loosing core passes stopper slot and tiltedly looses core and is cascaded.
The beneficial effects of the utility model are: the mechanism that this programme adopts the slip insert that ejects for three times and tiltedly loose core to cooperatively interact, and ensure that article removal is smooth, improve die life and quality of item, reduce mold repair cost.
Accompanying drawing explanation
Fig. 1 is that the utility model one ejects oblique core-drawing demoulding mechanism schematic diagram for three times;
Fig. 2 is that the utility model one ejects oblique core-drawing demoulding mechanism top view for three times.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Fig. 1, shown in Fig. 2, one ejects oblique core-drawing demoulding mechanism three times, comprise cover half fixed head (1), cover half die cavity (2), cover half mold insert (9), dynamic mould fixing plate (8), dynamic model die cavity (3), it is characterized in that, cover half fixed head (1) described cover half die cavity is equipped with, described cover half mold insert (9) is fixed in cover half die cavity (2), dynamic mould fixing plate (8) is equipped with mould pin (4), thimble lower plate (7), described dynamic model die cavity (3) is fixed on dynamic mould fixing plate (8) by crura membranacea (4), dynamic model die cavity (3) is built with insert (10), tiltedly loose core (12) and interior straight jacking block (11), described thimble lower plate (7) is fixed with straight top (15) and oblique top (16) (17) (18), by the oblique top groove in insert (10) and straight inverted draw cut location, tiltedly loose core (12) be cascaded by the gathering sill on interior straight jacking block (11), guide post (14) of loosing core also is cascaded through (12) interior stopper slot of tiltedly loosing core, be fixed together by two groups of three parts of connecting, synchronous loading insert, be positioned in insert by insert stopper slot, dynamic mould fixing plate is provided with oil cylinder fixed cover (13), oil cylinder fixed cover (13) is connected with and ejects return oil cylinder (19), straight top (15) is fixed on thimble upper plate (5), guide post (14) of loosing core is fixed on plate in thimble (6).
During the demoulding, first movable model chamber (2) part and cover half die cavity (3) part die sinking is driven by injection machine power, after die sinking action completes, thimble lower plate (7) is driven by oil cylinder (19), plate (6) in thimble, thimble upper plate (5) is toward the motion of goods depanning direction, in motion process, thimble lower plate (7) drives oblique top (16) (17) (18) oblique slip, make it to depart from product, depart from by ejecting spacing straight top (15) and the product of making of gag lever post (20) one-level, in the thimble upper plate (5) that continues to move upward drives, Zhi Ding and combination of tiltedly loosing core upwards directly eject to ensure to eject space three times, by ejecting the spacing command range of gag lever post (20) secondary, continue to move upward, by being fixed on the stopper slot on the effect of the oblique jacking guide bar on thimble upper plate (5) and interior straight top (15), tiltedly loose core (12) and inwardly move downwards, make it to depart from product, so far article removal completes.Then, under the effect ejecting return oil cylinder (19), mechanism resets.This programme adopts and ejects oblique core-drawing demoulding mechanism three times, ensures that article removal is smooth, improves die life and quality of item.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure transformation utilizing the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
