But, injection mold in above-mentioned patent, its ejecting mechanism is to be directly fixed on driving mechanism, cannot well control its pusher dynamics, likely firmly excessive, the product being shaped is flown out, in addition, injection mold in above-mentioned patent, knock-pin is vertical with respect to workpiece, owing to can be subject to resistance in pusher process, cause discontinuity between the end of knock-pin and shaft, likely can make the shaft bending of knock-pin, in addition, knock-pin limited length in above-mentioned patent, in the time this knock-pin being substituted in the injection mold that die cavity grows, likely can workpiece cannot be released not because of the length of knock-pin.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of knock-pin not fragile for the above-mentioned state of the art, and ejecting force is large and use a knock-pin can adapt to the injection mold of the refrigerator drawer of different die cavitys.
For achieving the above object, the utility model provides following technical scheme:
A kind of injection mold of refrigerator drawer, be fixed on die frame, described injection mold includes cover half and the dynamic model that can separate or close up with described cover half, described cover half is fixed on die frame, described fixed half and moving half complements each other to form and can hold the die cavity that refrigerator drawer is placed in the time of matched moulds state, it is characterized in that:
Also include ejecting mechanism, described ejecting mechanism is mainly made up of knock-pin and lifter plate, described lifter plate and described dynamic model are separately positioned on the both sides of described cover half, described lifter plate be arranged on die frame and can on described die frame, do near or away from the movement of described cover half;
On described lifter plate, protrude and be provided with skewback, on described skewback, be provided with dovetail groove, dovetail shaped is arranged in the end of described knock-pin one end, and fastens with the mutual slippage of described dovetail groove, and the other end of described knock-pin is connected on cover half and end extends in die cavity through described cover half.
As preferably, on described die frame, be provided with guide pillar and cylinder, described lifter plate be set on guide pillar and can be under the driving of described cylinder along described guide pillar do near or away from the slip of described cover half.
As improvement, on described die frame, be provided with cylinder, on described cylinder, be connected with drive rod, described lifter plate be fixed on described drive rod and can with drive rod do near or away from the movement of described cover half.
As the specific embodiment, described knock-pin end formedly has a pushing block what be positioned at described die cavity one end, and described pushing block is against on described refrigerator drawer.
Compared with prior art, the utility model has the advantage of: by relative knock-pin and the oblique setting of cover half, the arm of force is longer, and the in the situation that of identical power, moment is large, and pusher is effective, and because knock-pin is oblique setting, not flexible damage; Ejecting mechanism includes lifter plate, on lifter plate, be fixed with skewback, on skewback, be provided with dovetail groove, knock-pin is slidably connected in dovetail groove, can utilize this structure to convert the vertical lifting of lifter plate the horizontal pusher motion of knock-pin end pushing block in die cavity to, can accurately control by controlling lifter plate the pusher displacement of knock-pin; In addition, in the time that the length of knock-pin is released die cavity by workpiece not, only current skewback need to be changed on a skewback with longer inclined-plane, and not change whole knock-pin.
