Abstract
The utility model discloses an injection mold belongs to the mould field, and it includes the merciful and peaceful back mould benevolence of front mould, front mould benevolence is established in back mould benevolence top, with the compound die, be equipped with the die cavity in the back mould benevolence, with moulded product, this kind of injection mold still includes injection structure, and injection structure is including moulding plastics the mouth of a river, the mould plastics sprue and the subchannel of moulding plastics, moulds plastics the mouth of a river for the entry of the sprue of moulding plastics, the sprue of the moulding plastics intercommunication subchannel of moulding plastics, the subchannel of moulding plastics intercommunication die cavity to carry out injection moulding to the die cavity, it is equipped with the screw valve on the subchannel to mould plastics to the mould plastics flow of subchannel of regulation. This kind of injection mold can adjust the flow of moulding plastics of the subchannel of moulding plastics, guarantee the die cavity to mould plastics the flow reasonable, reduce the product burr and produce.
Description
Technical field
The utility model relates to mould applications, particularly relates to a kind of injection mold.
Background technology
Injection forming mold, plastics are melted by heating in the heating cylinder of injection machine first, then under the promotion of screw in injection molding machine or piston, running gate system through nozzle and mould enters mold cavity, finally sclerosis sizing in die cavity, Here it is injection molding simple procedure, and injection mo(u)lding mould used is just injection forming mold. Injection mold is mainly used in the moulding of thermoplastic articles, all to inject raw material by injection moulding runner, but the injection moulding runner that in die, each part connects and injection moulding regrinding distance are different, in die, the material flow of each part is different, die part material is too many, causes finished product easily to produce burr.
Utility model content
For solving the above problems, the utility model provides a kind of injection mold, can regulate the injection moulding flow of injection moulding runner, ensures that the injection moulding flow of die cavity is reasonable, reduces product burr and produces.
Technical solution adopted in the utility model is: a kind of injection mold, comprises front cavity and rear cavity; Front cavity is located at rear cavity top, with matched moulds; In rear cavity, be provided with die cavity, with shaped article; This kind of injection mold also comprises injection structure, injection structure comprises injection moulding regrinding, injection moulding sprue and injection moulding runner, and injection moulding regrinding is the entrance of injection moulding sprue, and injection moulding sprue is communicated with injection moulding runner, injection moulding runner is communicated with die cavity, so that die cavity is carried out to injection mo(u)lding; Injection moulding runner is provided with screw valve, to regulate the injection moulding flow of injection moulding runner.
In technique scheme, screw valve and injection moulding runner are fixed by screw thread, are easy to the flow that passes through of set screw valve.
In technique scheme, every injection moulding runner is all provided with screw valve, to regulate the injection moulding flow of every injection moulding runner.
In technique scheme, cast sprue is that bellmouth and bottom end opening diameter are greater than top, on cast sprue bottom end opening madial wall, is provided with buffer stopper, and injection moulding regrinding and cast sprue and front cavity coaxially arrange; Buffer stopper makes injection moulding flow velocity mild, regulates the injection moulding flow effect of injection moulding runner more obvious, and effectively slows down high pressure sizing material injection moulding runner and die cavity generation are impacted, and improves die life.
In technique scheme, on the bottom end opening madial wall of described cast sprue, be symmetrically arranged with multiple buffer stoppers, strengthen slowing down effect, make injection moulding flow velocity mild, regulate the injection moulding flow effect of injection moulding runner more obvious.
In technique scheme, described buffer stopper outer surface is uniformly distributed multiple protruding particles, strengthens slowing down effect, makes injection moulding flow velocity mild, regulates the injection moulding flow effect of injection moulding runner more obvious.
In technique scheme, described buffer stopper is 45～60 degree with cast sprue bottom end opening madial wall and arranges, and slows down effectively, makes injection moulding flow velocity mild, regulates the injection moulding flow effect of injection moulding runner more obvious.
The beneficial effects of the utility model are: this kind of injection mold, injection moulding runner is provided with screw valve, can regulate the injection moulding flow of injection moulding runner, according to the adjusting that needs of product, make the injection moulding flow of every part in die cavity all reasonable, be difficult for making finished product to produce burr and cause end product quality poor.
