Description
Technical field
The utility model belongs to automobile lifter field, and in particular to injection molding worm gear inner hole retainer disconnecting device.
Background technique
To use worm gear on the motor of existing automobile lifter, worm gear will cooperate with shaft to be fixed, for save the cost,
Existing worm gear is all integrated injection molding, but since the through-hole aperture of worm gear is larger, is easy to become after being molded by mold
Shape is not only easily deformed, can also due to it is cold and hot exchange and the through-hole of shrinkage cavity, shrinkage cavity or deformation can not cooperate with shaft, generation
The problem of high rejection rate.
Therefore applicant comes up with one and increases the support equipments of multiple inside in injection molding worm gear, integrated injection molding, at
The through-hole circularity that type comes out is good, indeformable, and internal support equipment is detachable, but the support leg inside the injection molding worm gear
Artificial cutting by hand is needed, there are three support legs, cuts slow, inefficiency in this way, and there is presently no a kind of relatively good
Technology solves.
Summary of the invention
Aiming at the shortcomings in the prior art, the utility model provides injection molding worm gear inner hole retainer disconnecting device, comes
Solve the problem of that the existing injection molding worm gear with support leg needs artificial cutting support leg inefficiency by hand.
The utility model is achieved through the following technical solutions.
Injection molding worm gear inner hole retainer disconnecting device, including rack are provided with rotatable turn in the rack
Disk, circular array shows multiple mounting holes on the turntable, and injection molding worm gear is placed in the mounting hole, is set in the rack
It is equipped with out slug hole and out finished parts hole, the side of the rack is provided with plateau, it is provided in the plateau by piling,
It is described by piling by cylinder control up and down, it is described by the lower section of piling and to be provided with baffle right above turntable,
The baffle is in circular ring shape.New equipment can disposably shoot down waste material, reduce artificial operation, increase the efficiency of production.
Preferably, the turntable is gear wheel, the side of the turntable is provided with pinion gear, the pinion gear
Drive gear wheel rotation.
Preferably, be provided with arc track in the rack, the arc track connect out slug hole and go out at
Product part hole.
Preferably, the diameter for going out slug hole is identical as the diameter of waste material inside injection molding worm gear.
Compared with prior art: by the press device that setting is intermittent, the waste material in worm gear is got through, obtains finished parts,
Improving productivity.
Detailed description of the invention

Specific embodiment
With reference to the accompanying drawing with specific embodiment, the utility model is described further.
Injection molding worm gear inner hole retainer disconnecting device, including rack 1 are provided in the rack 1 rotatable
Turntable 2, circular array shows multiple mounting holes 4 on the turntable 2, and injection molding worm gear, the machine are placed in the mounting hole 4
It is provided with out slug hole 12 and out finished parts hole 9 on frame 1, the side of the rack 1 is provided with plateau 7, in the plateau 7
It is provided with by piling 5, it is described to be controlled up and down by piling 5 by cylinder 6, it is described by the lower section of piling 5 and positioned at turntable 2
Surface is provided with baffle 8, and the baffle 8 is in circular ring shape, and the turntable 2 is gear wheel, and the side of the turntable 2 is set
It is equipped with pinion gear 3, the pinion gear 3 drives gear wheel rotation, is provided with arc track 11 in the rack 1, described
Arc track 11 connects out slug hole 12 and out finished parts hole 9, in the diameter for going out slug hole 12 and injection molding worm gear
The diameter of portion's waste material is identical.
It is molded worm gear, injection molding worm gear includes through-hole, and the support leg of three annular arrays of setting, described in the through-hole
One end of support leg is connect with the inner ring of injection molding worm gear, and the other end is connect with the second annular ring, is set in second annular ring
It is equipped with reinforcing member, annular setting is there are three connecting pin on the reinforcing member, and the connecting pin is connect with the second annular ring, institute
The center of the reinforcing member stated is arranged surplus item, and the support leg includes rectangle above and following trapezoidal, and described the
The outer ring of second ring circle is provided with positioning protrusion, and the positioning protrusion is adjacent with support leg.
In injection molding process, due to many bracing means of the through-hole integrated injection molding in injection molding worm gear,
Injection-moulded plastic flows into runner by sprue, and inflow type is intracavitary, successively injection molding worm gear, surplus item, support leg, the second annular
Circle, reinforcing member and surplus item.
Injection molding worm gear is put into the first station of turntable 2, the first station is located at slug hole 12 and out finished parts hole 9
Between mounting hole 4, injection molding worm gear is put into mounting hole 4, pinion gear 3 stepper motor driving under, turntable 2 clockwise revolve
Turning a station, reaches the underface for pressing piling 5 and baffle 8, baffle 8 blocks the outer ring of injection molding worm gear, and cylinder 6 starts at this time,
Drive and decline by piling 5, by piling 5 to the support leg of three annular arrays and whole parts of support leg inner ring carry out by
Pressure, due to three support legs be molded worm gear outer ring connect be not it is especially more, can effectively remove.
The finished parts finished are removed as turntable 2 continues to rotate clockwise, reach up to out finished product along arc track 11
At 9 position of part hole, since the aperture for going out finished parts hole 9 is big, finished parts are fallen at this time.
The protection scope of the utility model includes but is not limited to embodiment of above, and the protection scope of the utility model is to weigh
Subject to sharp claim, replacement, deformation, the improvement that those skilled in the art that any pair of this technology is made is readily apparent that are each fallen within
The protection scope of the utility model.
