Background technology
At present, the engineering plastics cage injection mold of many cast gates injection mo(u)lding, all adopts in the design aspect of sub-runner
With usual manner, the equally distributed sub-runner of circumferencial direction is designed on core die joint, rely on the processing essence of machining center
Spend and to ensure the uniformity of sub-runner.The design of this mode, even if through it was verified that especially high-precision equipment also cannot
Realize the theoretic uniformity of sub-runner, result necessarily brings plastic melt to pass through each sub-runner and cast gate from sprue, arrives
Reach in this section of path process of mold cavity, the inhomogeneities of flow, lead to the unbalanced of die cavity each portion mold filling.And mold filling is uneven
Many harmful effects are caused to retainer, mainly has: 1, local produces stress concentration；2nd, buckling deformation；3rd, poor dimensional precision；4、
Circularity is exceeded；5th, poor mechanical property；6th, each hole position pull-off force is unbalanced.
Content of the invention
In view of the problem that prior art exists, the purpose of this utility model is to provide a kind of engineering plastics cage injection mould
The flow passage structure of tool, reaches plastic melt uniform flow, and mold cavity each portion mold filling equalizes, thus ensureing that retainer product does not produce
Raw stress concentration, no buckling deformation, product size high precision, circularity is good, excellent in mechanical performance, and the equilibrium of each hole position pull-off force.
To achieve these goals, this utility model be the technical scheme is that a kind of engineering plastics cage injection
Mould flow passage structure, including sprue bush, sprue, sub-runner, cast gate, flow adjustment screw and core；The one of described sprue
End is connected with sprue bush, and the other end connects sub-runner；One end of sub-runner is connected with sprue, and the other end is connected with cast gate；
The quantity of described sub-runner is corresponded with the fenestra quantity of retainer；Flow adjustment screw is arranged on each sub-runner, spiral shell
Nail is threaded connection mode and is connected with core；Material is arranged at sub-runner one end near cast gate push rod.
The end of described sprue arranges slag well with the intersection of sub-runner.
Described flow adjustment screw is arranged on the middle part of sub-runner.
Setting big flow adjusting screw and two flow adjustment screws of low discharge adjusting screw on each described sub-runner,
Big flow adjusting screw is arranged on the position on each sub-runner near sprue, and low discharge adjusting screw is arranged on each shunting
Near the position of cast gate on road.
Major advantage of the present utility model is, is provided with flow adjustment screw in the middle part of sub-runner.Flow is adjusted
Section screw is threaded connection mode and is connected with core, and flow adjustment screw can be rotated by the twisting of screwdriver, adjusts it
Ride out in sub-runner, so that the sectional area that plastic melt flows through sub-runner is variable it is achieved that each shunts
The melt flow scalable in road.In product processing, can arbitrarily adjust, be finally reached stream according to the difference of flow everywhere
Amount is consistent.
