Abstract
The invention discloses a spiral demolding mechanism comprising a movable mould push plate, a stationary mould insert, a fixed mould core, a rotary mould core, a driving gear, a driven gear and a motor; the movable mould push plate is fixed on a movable mould and located at the bottom of a mould cavity; the stationary mould insert is fixed on a stationary mould; the fixed mould core, the rotary mould core and the stationary mould insert form a mould cavity of an injection-molded part; the fixed mould core and the rotary mould core are both located in the movable mould, and the rotary mould core is sleeved on the fixed mould core; the lower end of the rotary mould core is fixedly provided with the driven gear; one side of the driven gear is provided with a driving gear meshed with the driven gear; and the driving gear is fixed on a main shaft of the motor. The spiral demolding mechanism is rapid in demolding, simple in structure, lower in manufacturing cost and convenient to maintain.
Description
Technical field
The present invention relates to a kind of structure of injection mold, the spiral mould emptier in especially a kind of injection mold belongs to the injection mold technical field.
Background technology
Existing plastics Bottle and bottle cap is basically through being threaded, and through the screwed bottle cap, reaches the effect of sealing.Some sealing requirements than high product on, often its thread groove is deep, the thread on the corresponding bottle cap is also just than higher.Generally process for the injection moulding of this type bottle cap; Scrappage when reducing the moulding demoulding, the complete demoulding, a lot of injection mold manufactories commercial city is to be employed in cover half to increase a rotating core; A plurality of rotary guides are set on dynamic model; Utilize the rotating core rotation of gear driven cover half, when die sinking, moulding is screwed out.When adopting this mode demoulding, because the factors such as labyrinth of the dynamics of die sinking, mould, the scrappage of moulding is very high, and the screw thread on the moulding also is pulled out of shape often; And in order to increase output, existing injection mould all is a combination die; All will there be a rotating core position that is positioned at each core on the cover half, and mould has just very bothered when maintenance like this; When increasing service worker labour intensity, a lot of maintenance costs have also been increased.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed a kind of simple in structure, processing cost is low, and spiral mould emptier easy to maintenance.
Technical solution of the present invention is achieved in that a kind of spiral mould emptier, comprises dynamic model push pedal, fixed die insert, fixedly core, rotating core, driving gear, driven gear and motor; Said dynamic model push pedal is fixed on the dynamic model, and is positioned at the bottom of die cavity; Said fixed die insert is fixed on the cover half; Said fixedly core, rotating core and fixed die insert form the die cavity of moulding jointly; Said fixedly core and rotating core all are positioned at dynamic model, and rotating core is enclosed within fixedly on the core; The lower end of said rotating core is fixed with driven gear; One side of said driven gear is provided with the driving gear that is meshed with it; Said driving gear is fixed on the main shaft of motor; After the die sinking, motor drives driving gear and rotates, and then drives the driven gear rotation, makes rotating core rotate, and meanwhile, push pedal slowly ejects moulding, accomplishes the demoulding.
Preferably, also be engaged with a transition gear between said driving gear and the driven gear.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Spiral mould emptier of the present invention, it adopts motor, gear to drive to be positioned at the rotating core rotation on the fixedly core of dynamic model, and push pedal simultaneously outwards ejects moulding, and the demoulding is rapid, and this mould emptier is simple in structure, and manufacturing cost is lower, and easy to maintenance.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Structural representation when accompanying drawing l is a spiral mould emptier matched moulds of the present invention;
After accompanying drawing 2 is spiral mould emptier of the present invention die sinking, the plan structure sketch map of dynamic model;
Wherein: 1, cover half; 2, fixed die insert; 3, dynamic model push pedal; 4, die cavity; 5, rotating core; 6, fixing core; 7, dynamic model; 8, driven gear; 9, transition gear; 10, motor; 11, driving gear.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Be depicted as a kind of spiral mould emptier of the present invention like accompanying drawing 1,2, comprise dynamic model push pedal 3, fixed die insert 2, fixedly core 6, rotating core 5, driving gear 11, driven gear 8 and motor 10; Said dynamic model push pedal 3 is fixed on the dynamic model 7, and is positioned at the bottom of die cavity 4; Said fixed die insert 2 is fixed on the cover half 1; Said fixedly core 6, rotating core 5 and the fixed die insert 2 common die cavities 4 that form mouldings; Said fixedly core 6 all is positioned at dynamic model 7 with rotating core 5, and rotating core 5 is enclosed within fixedly on the core 6; The lower end of said rotating core 5 is fixed with driven gear 8; One side of said driven gear 8 is provided with the driving gear 11 that is meshed with it; Said driving gear 11 is fixed on the main shaft of motor 10; Also be engaged with a transition gear 9 between said driving gear 11 and the driven gear 8; After the die sinking, motor 10 drives driving gear 11 and rotates, and then drives driven gear 8 rotations, makes rotating core 5 rotate, and meanwhile, dynamic model push pedal 3 slowly ejects moulding, accomplishes the demoulding.
Above-mentioned spiral mould emptier, when being installed in the combination die, it drives two above driven gears 8 respectively through transition gear 9 and rotates, and adopts this spiral mould emptier, and the demoulding is rapid, and this mould emptier is simple in structure, and manufacturing cost is lower, and is easy to maintenance.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
