Throttling pillar is movably set in the first through hole, which is equipped with a limited block, and the limited block is living
It is dynamic to be set in second through-hole；
Elastic element is movably arranged in second through-hole, and the elastic element is sheathed on the throttling pillar；
Third through-hole is set in the mother module core and is conducted with second through-hole, along the third through-hole to
Under direction be equipped with fourth hole；
Fastener is movably set in the third through-hole, and the upper end of the fastener is fixedly connected on the limited block
On, and its lower end is fixed on a countersunk head.
Optionally, the diameter of the first through hole is less than the diameter of second through-hole.
Optionally, the diameter of the throttling pillar is greater than the width of the runner.
Optionally, the throttling pillar is greater than the height of the runner in the moving distance of second through-hole.
Optionally, the diameter of the third through-hole is less than the diameter of the fourth hole.
Optionally, the fastener is fastening screw.
Compared to the prior art, throttling pillar mechanism of the invention drives throttling pillar mobile, to rise by turn Fastener
To the effect of throttling；Throttling pillar is set to return to home position when not needing throttling, then through elastic element promotion.The throttling pillar machine
Structure has ended the flowing of plastic rubber material by using throttling pillar, to fill plastic rubber material to specified die cavity, realizes in same cover die
Multiple product is produced in tool.Throttling pillar mechanism of the invention, which is not only simple in structure, to be applied conveniently, but also shortens molding cycle,
Reduce cost of labor.
[Detailed description of the invention]
Fig. 1 is painted a kind of structural schematic diagram of three template dies equipped with throttle valve.
Fig. 2 is painted the structural schematic diagram of throttling pillar mechanism of the invention.
Fig. 3 is painted structural schematic diagram when throttling pillar mechanism current floe condition of the invention.
Fig. 4 is painted the partial schematic diagram of Fig. 3.
[specific embodiment]
It is preferably real below in conjunction with of the invention one further to illustrate technological means and its effect adopted by the present invention
It applies example and its attached drawing is described in detail.
Shown in please see Fig. 2 to Fig. 4, the present invention provides a kind of throttling pillar mechanisms 200, are applied in a mold, the mould
Tool includes upper mounted plate 201, stripper plate 202, caster 203, mother module core 204, male die core 205, male template 206, upper ejector plate
207, the caster of lower liftout plate 208 and bottom plate 209, the mold is equipped with an at least runner 2031, the throttling pillar machine
Structure 200 includes:
First through hole 210 is set in the caster 203, is equipped with the along 210 downwardly direction of first through hole
Two through-holes 220；
Throttling pillar 230 is movably set in the first through hole 210, which is equipped with a limited block
231, which is movably set in second through-hole 220, which is used to limit the movement of throttling pillar 230
Distance；
Elastic element 240 is movably arranged in second through-hole 220, and the elastic element 240 is sheathed on the throttling
On column 230, which is used to that throttling pillar 230 is pushed to return to home position；
Third through-hole 250 is set in the mother module core 204 and is conducted with second through-hole 220, along this
Three through-holes, 250 downwardly direction is equipped with fourth hole 260；
