Description
Technical field
The utility model relates to a kind of injection mold, and more particularly, it relates to a kind of injection mold being convenient to throttling.
Background technology
Injection mold is that one is applied on injection machine, the mould applied for the production of the product of injection mo(u)lding, and plastics are made all by injection molded through injection mold substantially.Material under the molten condition of injection moulding in the die cavity of guiding gutter runner mold, completes injection moulding from cast gate.Due to present large multi-mould being all carry out a multi-cavity mold, a cast gate, through too much bar guiding gutter, flows in die cavity and carries out injection moulding.
Usually because some die cavity may have been gone bad, or sometimes do not need the injection moulding of disposable so cavity, so just need a kind of similar guiding gutter that controls with the device of switch to flow to and formulate die cavity, or close some guiding gutters.
Existing application number be 201210442848.0 Chinese patent disclose a kind of mould structure with runner pole changer, it comprises can the flow channel switch of even opening and closing guiding gutter.Although this flow channel switch effectively can control the opening and closing of guiding gutter, function ratio is more single, and a switch can only control a guiding gutter, can not control multiple guiding gutter.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of by rotating the injection mold regulating the connection of each bar guiding gutter to reach restriction effect.
For achieving the above object, the utility model provides following technical scheme: a kind of injection mold being convenient to throttling, comprise cover half, base plate, described cover half is provided with some guiding gutters, for the cast gate of charging, several die cavities, the guiding gutter being communicated with die cavity is intersected in node with the guiding gutter being communicated with cast gate, described node is provided with switching device, described switching device comprises revolving part, actuator, keeper, described revolving part surface is provided with the runner for being communicated with many guiding gutters, described runner is provided with at least three openings docked with guiding gutter notch, described actuator drives the rotation of described revolving part to make described opening dock with guiding gutter notch or misplace.
By adopting technique scheme, owing to revolving part there being the runner at least three openings and connection opening, utilize and rotate revolving part, opening is made to dock from different guiding gutter notches or misplace, both the die cavity that a guiding gutter injection moulding is all can have been utilized, also can close a part of die cavity, so just can adjust the opening and closing of each die cavity flexibly, have large improvement than original single function of switch that can only have.
The utility model is set to further: described revolving part is cylindrical shape, conflicts bottom described revolving part with described base plate, and described cover half is provided with the through hole rotated for described revolving part.
By adopting technique scheme, columniform revolving part is comparatively stable, can rotate, close structure in the through hole of cover half.
The utility model is set to further: described actuator comprises drive rod, and described drive rod one end is fixedly connected with described revolving part, and the described drive rod other end is positioned at described base plate external.
By adopting technique scheme, because drive rod one end and revolving part are fixed, rotation can be rotated by driven rotary part by drive rod.The drive rod other end is positioned at described base plate external, and drive rod is longer, and such people directly can rotate with hand the actuator being positioned at outside just can regulate revolving part, thus completes the adjustment to revolving part.
The utility model is set to further: described keeper comprises several hoodles, spring, and described hoodle is embedded in bottom described revolving part, and described base plate is provided with the locating slot corresponding with described hoodle position, described Spring driving hoodle and described locating slot clamping.
The utility model is set to further: described hoodle is all circumferentially uniformly distributed, and described hoodle quantity is 4.
By adopt technique scheme, revolving part rotation in, when hoodle is corresponding with the locating slot position on base plate time, spring can drive hoodle and locating slot clamping, can hinder the rotation of revolving part, ensures the location of revolving part, time used in everyday, revolving part can not be shifted.When needs revolving part time, at least firmly a little greatly a bit, directly can depart from from locating slot by driving spring, ensure that revolving part can continue to rotate.This project organization is simple, and operate conveniently, effect is effective, can Reusability repeatedly.
The utility model is set to further: described switching device controls the connection of three guiding gutters, and described flow channel shape is T-shaped.
By adopting technique scheme, T-shaped runner by rotating, can close left and right any one guiding gutter, makes material that cast gate flows out the arrangement of people can enter the die cavity of formulation, has reached the function of a multiple guiding gutter opening and closing of switch control rule.

Detailed description of the invention
Referring to figs. 1 through Fig. 4, the injection mold embodiment that the utility model is convenient to throttling is described further.
Be convenient to an injection mold for throttling, comprise cover half 1, base plate 2, cover half 1 upper, base plate 2 under.Cover half 1 is provided with some guiding gutters 11, the cast gate for charging, 8 die cavities 12, the distribution of guiding gutter 11 as shown in Figure 1, guiding gutter 11 forms netted, the injection moulding materials flowed out in a cast gate are by multiple each die cavity 12 of guiding gutter 11 runner 31, the joint of guiding gutter 11 is node, each node is all connected with three guiding gutters 11, article three, guiding gutter 11 is in T shape, node is provided with a revolving part 3, revolving part 3 is provided with runner 31 on the surface, runner 31 is also T-shaped, and runner 31 has corresponding three openings 32.Each opening 32 is in the same size with the notch of guiding gutter 11, can ensure that material keeps stable when flowing.Rotate revolving part 3, opening 32 is made to dock from different guiding gutter 11 notches or misplace, both the die cavity 12 that the injection moulding of a guiding gutter 11 is all can have been utilized, also a part of die cavity 12 can be closed, so just can adjust the opening and closing of each die cavity 12 flexibly, have large improvement than original single function of switch that can only have.T-shaped runner 31 by rotating, can close left and right any one guiding gutter 11, makes material that cast gate flows out the arrangement of people can enter the die cavity 12 of formulation.
Cover half 1 is provided with the through hole holding this revolving part 3 above, and revolving part 3 is cylindrical, and revolving part 3 and through hole closely cooperate, and almost do not have gap each other.The bottom of revolving part 3 fixedly wears a drive rod 4 for rotating, and one end of this drive rod 4 is outside at base plate 2.And drive rod 4 is longer, such people directly can rotate with hand the actuator being positioned at outside just can regulate revolving part 3, thus completes the adjustment to revolving part 3.
Be provided with a keeper for being located by revolving part 3 bottom revolving part 3, keeper is made up of spring 34, hoodle 33, and hoodle 33 always has four, is circumferentially uniformly distributed.Hoodle 33 is embedded in bottom revolving part 3, the corresponding spring 34 of each hoodle 33.Base plate 2 is provided with the locating slot 21 corresponding with hoodle 33 position.
Revolving part 3 is when rotation, and when hoodle 33 is corresponding with locating slot 21 position on base plate 2 time, spring 34 can drive hoodle 33 and locating slot 21 clamping, the rotation of revolving part 3 can be hindered, ensure the location of revolving part 3, time used in everyday, revolving part 3 can not be shifted.When needs revolving part 3 time, at least firmly a little greatly a bit, directly can depart from from locating slot 21 by driving spring 34, ensure that revolving part 3 can continue to rotate.This project organization is simple, and operate conveniently, effect is effective, can Reusability repeatedly.
