Abstract
A core pulling mechanism adopting a straight ejection block for a mold of an automobile headlamp decorative frame comprises an upper compound plate and a lower compound plate, wherein the upper compound plate is connected with a fixed mold plate through a runner plate, support parallels and an ejection plate are mounted on the lower compound plate, a movable mold plate is mounted on the support parallels, the decorative frame formed through injection is arranged between the movable mold plate and the fixed mold plate, an assembly hole is formed in the decorative frame, and an ejection pin is in contact with the bottom surface of the decorative frame after penetrating the movable mold plate. The mechanism is characterized in that the ejection block is mounted in the ejection plate, an ejection rod is connected to the ejection block, an inner sliding block is arranged in the ejection rod in a sliding manner, one end of the inner sliding block is matched with the assembly hole, a lock block is mounted in the movable mold plate, an inclined guide groove is formed in the lock block, and the other end of the inner sliding block is matched with the inclined guide groove of the lock block. Compared with the conventional method in which a spring is used to jack up an inner pulling block, the utility model adopting the technical scheme has the advantages that the inner sliding block is driven by the straight ejection block for core pulling, so that the mechanism has more stable and reliable actions, long service life and simple structure, and can save cost and investment.
Description
Technical field
The utility model relates to a kind of automobile front escutcheon mould, particularly relates to the straight jacking block core-pulling mechanism of escutcheon pilot hole, belongs to the mould of plastics field.
Background technology
Adopt injection mold to produce plastic product, for example the escutcheon of automobile front is shaped on pilot hole in the escutcheon, and pilot hole and automobile front lampshade fix.When mold releasability, after needing earlier pilot hole to be loosed core, could be with the smooth ejection device of escutcheon.The pilot hole mould of prior art escutcheon adopts three template types, promptly comprise solid plate, moving platen and moving clamping plate, mounting spring between moving platen and moving clamping plate, utilize spring force when die sinking with moving platen jack-up, moving platen is taken out piece in driving, in take out piece and cooperate with angled-lift splits and drive the pilot hole fuse and loose core, the shortcoming of its existence is: one is three template mold complex structures, and cost of investment is big; The 2nd, utilize spring jack-up, fluctuation of service, service life is short.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, provides the straight jacking block of a kind of employing to drive inner slide and looses core, and simple in structure, cost investment is few, and is stable, the straight jacking block core-pulling mechanism of automobile front escutcheon mould of long service life.
The technical scheme of the straight jacking block core-pulling mechanism of the utility model automobile front escutcheon mould is: comprise compound plate and following compound plate, last compound plate connects solid plate through runner plate, mould pin and top board are installed on the following compound plate, connect thimble on the top board, on the mould pin moving platen is installed, the escutcheon that injection mo(u)lding is arranged between moving platen and the solid plate, be shaped on pilot hole in the escutcheon, thimble passes moving platen and contacts with the escutcheon bottom surface, it is characterized in that in the described top board jacking block being installed, connect push rod on the jacking block, sliding in the push rod is provided with inner slide, and of inner slide matches installation lock dog in the described moving platen with pilot hole, being shaped on inclined guide groove in the lock dog, matches with the inclined guide groove of lock dog in the other end of inner slide.
The straight jacking block core-pulling mechanism of automobile front escutcheon mould 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, top board drives on thimble and the jacking block and pushes up, and jacking block drives push rod, push rod drives the inclined guide groove slip of built-in inner slide along lock dog of sliding, inner slide and pilot hole are loosed core disengage, thimble ejects escutcheon outside the mould simultaneously, and the demoulding is finished.This programme adopts straight jacking block to drive the mode that inner slide is loosed core, and compares with taking out in the existing spring jack-up, move more stable, reliable, long service life, simple in structure, cost investment province.
The straight jacking block core-pulling mechanism of automobile front escutcheon mould of the present utility model, described moving platen bottom mounting plate, lock dog is connected on the fixed head, and push rod passes fixed head, and fixed head has been arranged, and it is firm, convenient that lock dog is installed.
