Description
Technical field
the present invention relates to a kind of mould, be specifically related to a kind of automobile outer rear-view mirror shell core-pulling die.
Background technology
Automobile outer rear-view mirror shell is one of key factor evaluating automobile appearance quality, and its appearance requirement moulding is beautiful, and curved surface is smooth, and internal structure is surely leaned on, easy to assembly.All be shaped with in the side of automobile outer rear-view mirror shell and be difficult to process and shaping back-off face, when Design of Dies, general employing 2 kinds of schemes: the first be by be difficult to processing and shaping back-off face make straight top, then artificial pickup, this can cause molding cycle to increase by 20%, add cost of labor and injection moulding cost per unit, artifact, causes percent defective very high simultaneously; The second to be difficult to processing and rear mold tunnel is made in shaping back-off face, and design can carry out automated production, but processing difficulties like this, and assembling is inconvenient, if while die damage, also not easy-maintaining.
Notification number is disclose a kind of automobile rearview mirror outer casing mold core-pulling mechanism in the patent of CN201604241U, it adopts oil cylinder, piston, outer slide and knock-pin to coordinate and realizes core_pulling demoulding, when the demoulding, solid plate and moving platen die sinking is driven by injection machine, outer slide is driven outwards to slide by oil cylinder again after die sinking completes, make outer slide depart from recessed (i.e. back-off) part of epi mirror shell, finally ejected by epi mirror shell by knock-pin, the demoulding completes.It can regulate stroke of loosing core, and loose core of oil cylinder reliable in action, stable, but but there are the following problems: (1) structure is compact not, outer slide runs and has some setbacks; (2) can only shaping simple back-off form, well can not complete the demoulding for more complicated outside rear-view mirror shell back-off, versatility is not high.
Summary of the invention
The object of this invention is to provide a kind of automobile outer rear-view mirror shell core-pulling die, make its compact conformation, loose core that it is smooth and easy to run, can shaping more complicated outside rear-view mirror shell back-off.
Automobile outer rear-view mirror shell core-pulling die of the present invention, comprise slider component, moving platen, be arranged on the mavable module core in moving platen, be arranged on the oblique top in mavable module core, the oil cylinder being arranged on the take-up housing on moving platen sidewall and being arranged on take-up housing sidewall, described moving platen and take-up housing all offer the chute slided for described slider component, described slider component comprises the slide block be connected with the axle of loosing core of described oil cylinder, slide block core, spring and stop screw, the bottom of slide block is provided with the slide rail coordinated with described chute, the sidepiece of slide block has a downward inclined plane, this inclined plane offers T-shaped guide groove, the inclined plane that slide block core is inclined and mounted on slide block is slidably matched with T-shaped guide groove, and its head is against described oblique top, afterbody is against the top of slide block, the top side of slide block offers downward-sloping spacing via hole, this spacing via hole is stepped hole, its incline direction is consistent with the incline direction of described inclined plane, the afterbody side of slide block core offers downward-sloping screw mounting hole, this screw mounting hole is stepped hole, its incline direction is consistent with the incline direction of described inclined plane, a described spring part is positioned at spacing via hole and is resisted against on the step end face of spacing via hole, another part is positioned at screw mounting hole and is resisted against on the step end face of screw mounting hole, described stop screw interts in the spring, and spin with screw mounting hole.
In order to locking sliding block core and to make slide block core locate more accurate, described slide block core offers U-shaped breach, described moving platen is provided with the U-shaped locating piece matched with described U-shaped breach.
Its course of work is as follows:
During the demoulding, oil cylinder pulls slide block in chute to left movement by axle of loosing core, slide block core moves downward along the inclined plane of slide block (T-shaped guide groove) under spring force simultaneously, slide block core is made to depart from product rib, when spacing distance played after, oil cylinder pulls on movable slider, slide block core under the pulling of stop screw together with slide block to left movement, depart from back-off, finally by oblique top, outside rear-view mirror shell is ejected.
During matched moulds, oblique top return, oil cylinder is moved right in chute by axle band movable slider of loosing core, slide block core first touches oblique top, slide block continues motion, and slide block core moves upward along the inclined plane of slide block (T-shaped guide groove) under the effect of oblique top, gets back to U-shaped locating piece locking restraining position, make it location, slider component is locked by the motoricity of axle of loosing core by last oil cylinder.
The present invention has following effect:
Slide block and being slidably matched of slide block core adopt T-shaped guide groove, and realize being connected by stop screw and spring, and compact conformation is reliable, moves smooth and easy when the demoulding or matched moulds, and the shaping more complicated outside rear-view mirror shell back-off of its energy, versatility is good.Simultaneously its Stability Analysis of Structures reliable, assemble simple, easy to maintenance, the continuity of automated production in enormous quantities can be realized.
