Abstract
The invention discloses a swaying block-type double-ejection injection mold which comprises a mold core, a part-pushing plate, an ejector rod, and a back ejection plate, and further comprises a push rod and a front ejection plate, wherein the ejector rod is arranged on the back ejection plate, and is connected into the front ejection plate and the mold core sequentially in a movable sleeving manner; the part-pushing plate is connected outside the mold core in a movable sleeving manner; the front ejection plate is arranged in front of the back ejection plate; the push rod is arranged on the front ejection plate; the free end of the push rod is in movable connection with the back end of the part-pushing plate. The swaying block-type double-ejection injection mold has the advantages that a double-ejection mechanism can be controlled mechanically through swing parts; the structure is sufficient in strength and wear resisting property; the guiding property is high; the skew phenomenon is avoided.
Description
Technical field
The present invention relates to a kind of swing block type Double-ejection injection mold, belong to injection mold ejecting mechanism technical field.
Background technology
At present, existing in die sinking process, need to there is ejecting mechanism that plastic products and the solidifying material in runner thereof are released or pulled out.Release fixed head and push pedal in order to clamp push rod.In push rod, be generally also fixed with release link, release link resets push pedal when moving, cover half matched moulds.But owing to once ejecting, make plastic stressed excessive produce distortion or damage, adopt secondary ejecting mechanism, to disperse knockout press, assurance plastic is deviate from die body intactly.
Summary of the invention
Object: in order to overcome the deficiencies in the prior art, the invention provides a kind of swing block type Double-ejection injection mold.
Technical scheme: for solving the problems of the technologies described above, the technical solution used in the present invention is:
A swing block type Double-ejection injection mold, comprises core, push piece plate, push rod, and rear top board, also comprises push rod, front top plate, on described rear top board, is provided with push rod, and described push rod is successively in mobile socket and front top plate, core; Described push piece plate movable sleeving is connected to core outside; Described front top plate is arranged at rear top board the place ahead, is provided with push rod on front top plate, described push rod free end and push piece plate rear end mobile link.
Also comprise centering block, spring, described centering block centre position is rotationally connected by rivet and front top plate upper end; Centering block right side is connected with spring one end, and the spring other end is connected with front top plate upper end.
Described centering block right-hand member is provided with arc-shaped protrusions.
Described centering block left-end point is set to arc disc.
Also comprise guide plate, described guide plate is arranged at front top plate upper end, guide plate inner side and centering block mobile link.
Described guide plate inner side is provided with groove, for centering block, departs from and is connected with rear top board.
As preferred version, also comprise release link, described rear top board front end is provided with release link, for the reset of push rod.
Beneficial effect: swing block type Double-ejection injection mold provided by the invention, to utilize goods of furniture for display rather than for use to realize the machinery of secondary ejecting mechanism is controlled, structure has sufficient intensity and anti-wear performance, and guidance quality is strong, without twisted phenomenon.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figure 1, a kind of swing block type Double-ejection injection mold, comprises core 1, push piece plate 2, push rod 5, rear top board 10, also comprise push rod 3, front top plate 8, on described rear top board 10, be provided with push rod 5, described push rod 5 moves in socket and front top plate 8, core 1 successively; Described push piece plate 2 movable sleevings are connected to core 1 outside; Described front top plate 8 is arranged at rear top board 10 the place aheads, is provided with push rod 3 on front top plate 8, described push rod 3 free ends and push piece plate 2 rear end mobile links.
Also comprise centering block 9, spring 7, described centering block 9 centre positions are rotationally connected by rivet and front top plate 8 upper ends; Centering block 9 right sides are connected with spring 7 one end, and spring 7 other ends are connected with front top plate 8 upper ends.
Described centering block 9 right-hand members are provided with arc-shaped protrusions.
Described centering block 9 left-end points are set to arc disc.
Also comprise guide plate 6, described guide plate 6 is arranged at front top plate 8 upper ends, guide plate 6 inner sides and centering block 9 mobile links.
Described guide plate 6 inner sides are provided with groove, for centering block 9, depart from and are connected with rear top board 10.
As preferred version, also comprise release link 4, described rear top board 10 front ends are provided with release link 4, for the reset of push rod 5.
Specific embodiment is as follows: while ejecting, and top board 10 after injector push rod promotes, and by the effect of centering block 9, move together with front top plate 8, promote push rod 3 and push rod 5 simultaneously, plastic is deviate from from core, complete and eject for the first time action, at this moment plastic is still contained on push piece plate 2.While continuing to eject, centering block 9, under guide plate 6 guide effects, is done clockwise and is swung, and top board 10 after throwing off stops front top plate 8, push rod 3, push piece plate 2 mobile, and push rod 5 continues reach, and plastic is ejected and fallen by force from de-part template chamber.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
