Description

Injection mold plastic side is interior reverse buckle demolding mechanism up and down
Technical field
The present invention relates to injection mold, particularly relate to injection mold plastic side interior reverse buckle demolding mechanism up and down.
Background technology
When after working of plastics injection mo(u)lding, if the sidewall of working of plastics is shaped with lug and lower lug, upper lug is shaped with downward back-off, lower lug is shaped with back-off upwards, namely upper and lower back-off is mutually corresponding, prior art does little by the degree of depth of upper and lower back-off, directly deviate from back-off by strong taking off again, therefore easily there is situations such as breaking in back-off, causes product rejection, scrappage is high, and owing to doing little by the back-off degree of depth, its fastening ability, when working of plastics and other parts assemble, it is unreliable to assemble, and affects result of use.
Summary of the invention
The object of the invention is the shortcoming existed to overcome prior art, provide a kind of structure simple, the demoulding is smooth, and yield rate is high, reverse buckle demolding mechanism in guarantee Product Assembly reliable injection mold plastic side is upper and lower.
In injection mold plastic side of the present invention is upper and lower, the technical scheme of reverse buckle demolding mechanism is: comprise compound plate and lower compound plate, under upper compound plate, cover half is set, between upper compound plate and cover half, Angle Pin is set, perforation is had in lower compound plate, lower compound plate arranges mould pin, lower compound plate between mould pin is arranged ejector retainner plate and lower ejector retainner plate, on, between lower ejector retainner plate, thimble is set, injector push rod contacts with below lower ejector retainner plate through perforation, mould pin arranges dynamic model, dynamic model arranges side action sliders, oblique guide hole is had in side action sliders, oblique guide hole matches with Angle Pin, the working of plastics of injection mo(u)lding is had between side action sliders and fixed half and moving half, the sidewall of working of plastics is shaped with lug and lower lug, upper lug is shaped with back-off, lower lug is shaped with lower back-off, on, lower back-off is corresponding, it is characterized in that: the drop-down rod aperture being shaped with the pull-up rod aperture under being tilted in described side action sliders and tilting upward, upper limit pull bar and upper oblique top are set in pull-up rod aperture, one of upper limit pull bar is shaped with upper limit position block, upper limit pull bar other end is connected with upper oblique top, upper oblique top head matches with upper back-off, internal projecting ring is shaped with in pull-up rod aperture, upper internal projecting ring contacts with upper limit position block is spacing, between upper oblique top and upper internal projecting ring, spring is set, lower limit pull bar and lower oblique top are set in drop-down rod aperture, one of lower limit pull bar is shaped with lower position block, lower limit pull bar other end is connected with lower oblique top, declivity top portion matches with lower back-off, lower internal projecting ring is shaped with in drop-down rod aperture, lower internal projecting ring contacts with lower position block is spacing, between lower oblique top and lower internal projecting ring, lower spring is set.
The invention discloses a kind of injection mold plastic side interior reverse buckle demolding mechanism up and down, when working of plastics injection mo(u)lding, lower compound plate band dynamic model pin, dynamic model, upper ejector retainner plate, lower ejector retainner plate, side action sliders and working of plastics move backward, mould die sinking, and while dynamic model backward movement, the Angle Pin of cover half matches with the oblique guide hole of side action sliders, and side action sliders is moved backward, while move laterally along oblique guide hole, and on, on lower spring then promotes under the effect of elastic force, lower oblique top, make it can not move laterally along with side action sliders, but because pull-up rod aperture and drop-down rod aperture are angling hole, therefore the upper back-off that oblique top moves down working of plastics is gradually gone up, lower oblique top moves up the lower back-off of working of plastics gradually, when the upper limit position block of upper limit pull bar contacts with upper internal projecting ring, when the lower position block of lower limit pull bar contacts with lower internal projecting ring, on, lower internal projecting ring is to upper, lower limit pull bar carries out spacing, on, lower limit pull bar is to upper, lower oblique top is spacing, and now side action sliders continues to move laterally, and on driving, lower oblique top outwards extracts working of plastics out, is finally driven by injector push rod, lower ejector retainner plate, on, lower ejector retainner plate drives thimble by working of plastics ejection device.This programme injection mold plastic side is interior reverse buckle demolding mechanism up and down; when side action sliders moves laterally; coordinated with oblique top by the tie rod hole tilted, the elastic force of recycling spring first withstands oblique top, makes oblique top first deviate from back-off; finally oblique top is taken out of laterally and loose core; structure is simple, and the demoulding is smooth, and yield rate is high; the degree of depth of product back-off need not be changed, thus ensure that Product Assembly is reliable.
Injection mold plastic side of the present invention is interior reverse buckle demolding mechanism up and down, described dynamic model is arranged the two pieces of side action sliders in left and right, in the side action sliders of two pieces, left and right, arranges upper and lower limit pull rod and upper and lower oblique top respectively.Described dynamic model is arranged four pieces of side action sliders all around, all around, in four pieces of side action sliders, upper and lower limit pull rod and upper and lower oblique top are set respectively.Can according to the structure needs of working of plastics, the side action sliders of design varying number, and upper and lower limit pull rod and upper and lower oblique top are set in side action sliders.
