The secondary ejection and pre-resetting integrated mechanism realizes the secondary ejection of injection products and the forced resetting of the mold.
Description
Technical field
The present invention relates to a kind of mold mechanism, relate in particular to a kind of Double-ejection and the integral mechanism that first resets.
Background technology
Due to the special shape of product or the requirement of production, after a demoulding has been moved, goods are still difficult to from die cavity to take out or can not Automatic-fallings, now just must increase a demoulding again and move and just can make goods come off.Sometimes for to avoid the stressed excessive of a demoulding goods, chamber as dark in thin-walled plastic or complex-shaped goods, easily make plastic break or be out of shape as once ejected, and adopt the secondary demoulding, to disperse knockout press, guarantees quality of item.
There are a lot of secondary ejecting mechanisms in injection mold field, and the present invention adopts Double Tops needle plate mechanism, when realizing Double-ejection, has realized the first reset of mould, effectively prevents that mould from wounding, and increases the life-span of mould.
Summary of the invention
In order effectively to prevent that mould from wounding, increase the life-span of mould, for achieving the above object, the technical solution used in the present invention is:
A kind of mould secondary ejects and the integral mechanism that first resets, comprise lower thimble panel, lower Ejector Retainer Plate, lower thimble panel and lower Ejector Retainer Plate pass through screw locking, it is characterized in that: this mechanism also comprises thimble panel, upper Ejector Retainer Plate, first resetting-mechanism long slab, first resetting-mechanism limited block, first resetting-mechanism movable block, upper thimble panel and upper Ejector Retainer Plate pass through screw locking, upper thimble panel and upper Ejector Retainer Plate are than lower thimble panel, lower Ejector Retainer Plate is long, on upper thimble panel, little limited block is installed, large limited block and nylon mode locker are installed on lower thimble panel, large spacing tile height is greater than the height of little limited block, the long slab that first resets is all installed in front template both sides, first resetting-mechanism limited block and first resetting-mechanism movable block have all been installed in the both sides of rear pattern plate, first resetting-mechanism movable block can freely rotate in the side of rear pattern plate around the axle of self upper end.
Further, there is rectangular indentation described upper thimble panel, the both sides of upper Ejector Retainer Plate, when matched moulds state, the lower end of first resetting-mechanism long slab is positioned at rectangular indentation place, and first resetting-mechanism movable block contacts with upper thimble panel and first resetting-mechanism long slab and upper thimble panel and upper Ejector Retainer Plate pushed back to the position of matched moulds.
Advantage of the present invention is: the present invention had both realized the Double-ejection of injecting products, has also realized the forced resetting of mould, has avoided largely interfering because of mold parts the infringement that ejector retainner plate does not reset and causes to mould.

The specific embodiment
Embodiment
The conventional structure of injection mold comprises that front mould panel A1, front template A0, rear pattern plate B0, mould pin B1, lower thimble panel B4, lower Ejector Retainer Plate B5 form.The mechanism that the present invention increases mainly comprises: upper thimble panel B2, upper Ejector Retainer Plate B3, first resetting-mechanism long slab 5, first resetting-mechanism limited block 6, first resetting-mechanism movable block 7, wherein go up thimble panel B2, upper Ejector Retainer Plate B3 than lower thimble panel B4, the long 30m of lower Ejector Retainer Plate B5, also have in addition some accessories, as: large limited block 1, little limited block 2, nylon mode locker 4 etc.Wherein go up thimble panel B2, upper Ejector Retainer Plate B3 is screwed.
It is upper that first resetting-mechanism long slab 5 is fixed on front template A0, and it is upper that first resetting-mechanism limited block 6 is fixed on rear pattern plate B0, and first resetting-mechanism movable block 7 is on rear pattern plate B0, rotatable.Nylon mode locker 4 is fixed on lower thimble panel B4, Main Function: lower thimble panel B4, the lower Ejector Retainer Plate B5 motion of traction when upper thimble panel B2, upper Ejector Retainer Plate B3 are ejected, when thimble panel B4, lower Ejector Retainer Plate B5 reach stroke instantly, large limited block 1 top stops ejecting motion to rear pattern plate B0, now nylon mode locker 4 will be forced to deviate from from upper thimble panel B2, upper Ejector Retainer Plate B3, thereby upper thimble panel B2, upper Ejector Retainer Plate B3 continue to eject, complete Double-ejection action.
The operation principle of injection mold is presented below.
Front mould panel A1 and front template A0 are fixed on the front panel of injection machine, are cover half; Rear pattern plate B0 etc. is dynamic model, is fixed on injection machine rear board.Main movement process is as follows:
After injection machine injection mo(u)lding, injection moulding machine mould open.The dynamic model of mould is followed rear mold plate of injection molding machine motion, and the first resetting-mechanism long slab 5 on front template A0 is away from upper thimble panel B2.It is upper that after giving up the throne, injection machine top rod is applied to Ejector Retainer Plate B3, now go up thimble panel B2 and upper Ejector Retainer Plate B3 will drive lower thimble panel B4 and lower Ejector Retainer Plate B5 will together with eject motion.After ejecting LAP, the large limited block 1 being arranged on lower thimble panel B4 is applied on rear pattern plate B0, thereby the lower thimble panel B4 of restriction and lower Ejector Retainer Plate B5 continue motion, nylon mode locker 4 on lower thimble panel B4 will be forced to deviate from from upper thimble panel B2 and upper Ejector Retainer Plate B3, ejects and has moved for the first time.Now, and upper thimble panel B2, upper Ejector Retainer Plate B3 will continue upwards to eject, and eject motion, until little limited block 2 be also applied to rear pattern plate B0 upper after, eject for the second time motion and also stop.Wholely eject motion and stop, after product ejects, mould matched moulds.In the process of matched moulds, under the drive of rear pattern plate B0, first resetting-mechanism long slab 5 moves down, first be applied on first resetting-mechanism movable block 7, first resetting-mechanism movable block 7 is applied on thimble panel B2, thereby force upper thimble panel B2 to reset, then matched moulds process finishes, carry out next one circulation.
Here it is Double-ejection and the integral mechanism that first resets, both realized the Double-ejection of injecting products, also realized the forced resetting of mould, avoided largely interfering because of mold parts the infringement that ejector retainner plate does not reset and causes to mould.
