Description

Injection mold oblique sliping type secondary core-pulling mechanism
Technical field
The utility model relates to a kind of injection mold oblique sliping type secondary core-pulling mechanism, belongs to the plastics machinery field.
Background technology
Adopt injection mold to produce plastic product, for example automobile rearview mirror mirror shell is shaped on buckle on the automobile rearview mirror mirror shell, needs after the injection mo(u)lding earlier buckle to be carried out the demoulding, just can be ejected outside the mould.The oblique Slipped Clove Hitch structure of the general employing of the prior art buckle demoulding, described oblique Slipped Clove Hitch structure is included in oblique slide bar is installed on the top mold plate, tiltedly on the slide bar angled-lift splits is installed, angled-lift splits matches with the buckle of mirror shell, drive on the top board by injection machine during the demoulding and push up, the outside slip of angled-lift splits that top board drives on the oblique slide bar disengages with buckle, by top on the push rod secondary mirror shell is ejected outside the mould again.The shortcoming of its existence is: tiltedly slide bar is oblique setting, and very inconvenience is installed, and influences the design in mold cools down water route; On the other hand, action instability when tiltedly slide bar is tiltedly sliding, angle ejector rod easy deformation, bending, even fracture, service life is short.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, and a kind of employing secondary mode of loosing core is provided, and the slide block of loosing core is easy for installation, reliable in action, and mould structure is simple, the injection mold oblique sliping type secondary core-pulling mechanism of long service life.
The technical scheme of the utility model injection mold oblique sliping type secondary core-pulling mechanism is: comprise cope match-plate pattern and lower bolster, cope match-plate pattern connects solid plate, fixed die insert is installed in the solid plate, the mould pin is installed on the lower bolster, in the mould pin top board is set, connect push rod on the top board, on the mould pin moving platen is installed, moving die insert is installed in the moving platen, constitute die cavity between moving die insert and the fixed die insert, moulding mirror shell is arranged in the die cavity, push rod passes moving platen and moving die insert contacts with the mirror shell, be shaped on buckle on the mirror shell, it is characterized in that described moving platen one side installation outer slide, big slide block in outer slide connects, interior big slide block contacts with buckle, on interior big slide block, be shaped on oblique chute and stopper slot, tiltedly on the chute interior small slide block is set, interior small slide block contacts with mirror shell inwall, and stop screw is installed in the bottom of interior small slide block, stop screw matches with stopper slot, and described outer slide drives outer taking out by oil cylinder.
Injection mold oblique sliping type secondary core-pulling mechanism of the present utility model, during the demoulding, at first drive moving platen and solid plate die sinking by injection machine power, after the die sinking, oil cylinder drives outer slide and takes out outward, big slide block outwards slided in outer slide drove, big slide block and buckle disengage in making, simultaneously, owing on interior big slide block, be shaped on oblique chute and stopper slot, tiltedly on the chute interior small slide block is set, and stop screw is installed in the bottom at interior small slide block, and stop screw matches with stopper slot, so when interior big slide block outwards slides, the oblique chute in interior small slide block edge is to lower slider, disengage with mirror shell inwall, big slide block outwards slided in outer slide continue to drive again, when sliding into stopper slot and contact with stop screw, small slide block outwards slides in driving, and the big slide block and the interior small slide block demoulding are finished in making.This programme adopts the slide block secondary mode of loosing core, reliable in action, stable, and long service life, slide block is easy for installation, and mould structure is simple.
Injection mold oblique sliping type secondary core-pulling mechanism of the present utility model is equipped with spring between described outer slide and the interior small slide block, and spring has been arranged, and as the starting force of interior small slide block to lower slider, small slide block is tiltedly smoothly sliding in making.Described oil cylinder has connecting plate, and connecting plate is installed on the outer wall of moving platen, and connecting plate has been arranged, and oil cylinder is easy for installation, firm.
