Description
Technical field
The utility model relates to a kind of motor cover mould wiring hole draw-in groove secondary core-pulling mechanism, belongs to the plastics machinery field.
Background technology
Adopt injection mold to produce plastic product, for example the pump motor lid is shaped on wiring hole on the motor cover, and wiring hole matches with coupling, so need the demoulding of loosing core of first butted line hole after the motor cover injection mo(u)lding, motor cover could be ejected outside the mould.But, firm for wiring hole is cooperated with coupling, need in wiring hole, be shaped on draw-in groove, draw-in groove has been arranged after, the slide block of loosing core of wiring hole can be blocked by draw-in groove when the demoulding, prior art adopts strong desorption method, utilizes the ductility of plastic material, and the wiring hole slide block of loosing core forces to loose core the demoulding from draw-in groove, cause draw-in groove to damage so sometimes, poor product quality, the percent defective height increases production cost.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming that prior art exists, a kind of employing secondary mode of loosing core is provided, makes the wiring hole and the draw-in groove demoulding smooth, production assurance, percent defective is low, the motor cover mould wiring hole draw-in groove secondary core-pulling mechanism that reduces production costs.
The technical scheme of the utility model motor cover mould wiring hole draw-in groove secondary core-pulling mechanism is: comprise cope match-plate pattern and lower bolster, cope match-plate pattern connects solid plate down, fixed die insert is installed in the cope match-plate pattern, 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, the fixed installation core is inserted on the moving platen, slide outside core is inserted cavity block is set, cavity block, core insert and fixed die insert between constitute die cavity, the moulding motor cover is arranged in the die cavity, be shaped on wiring hole on the sidewall of motor cover, be shaped on draw-in groove in the wiring hole, it is characterized in that on the described cavity block outer slide being installed, outer slide connects the wiring hole piece of loosing core, and wiring hole is loosed core and the draw-in groove slide block is installed in the piece, the draw-in groove slide block drives outer taking out by oil cylinder, in the draw-in groove slide block Angle Pin is installed, Angle Pin connects the draw-in groove fuse, and the draw-in groove fuse contacts with the draw-in groove of wiring hole.
Motor cover mould wiring hole draw-in groove secondary core-pulling mechanism of the present utility model during the demoulding, at first drives the draw-in groove slide block by oil cylinder and outwards slides, the draw-in groove slide block drives Angle Pin, Angle Pin drives the draw-in groove fuse to inner core pulling, and draw-in groove fuse and draw-in groove are disengaged, then, injection machine power drives moving platen and solid plate die sinking, after the die sinking, cavity block is outwards driven by power and slides, and drives outer slide simultaneously and outwards slides, outer slide drives the wiring hole piece of loosing core and looses core, and the demoulding is finished.This programme adopts the secondary mode of loosing core, at first driving the draw-in groove fuse by Angle Pin looses core, draw-in groove fuse and draw-in groove are disengaged, draw-in groove no longer blocks the wiring hole piece of loosing core, drive the wiring hole piece demoulding of loosing core of loosing core by outer slip again, make the wiring hole and the draw-in groove demoulding smooth, guarantee product quality, reduce product rejection rate, save cost.
