Abstract
The invention provides a sprue insert structure. A passage is arranged in a cylinder; the opening at the sprue entry end of the passage, which is connected with a die sprue, is small; and the opening at the other end of the passage is big. The invention has the advantages that the sprue insert structure can be automatically produced after technical improvement, so that the operation of manually repairing a water gap is reduced, manpower is reduced, automatic mass production is facilitated, waste is reduced, and the production cost of an enterprise is reduced.
Description
Technical field:
The present invention relates to the technical field of mould gate structure, relate in particular to a kind of sprue mold insert structure.
Background technology:
The Injection Industry plastic cement products adopts side to advance the cast gate mode now, when the complete rear injection machine cast gate of product injection moulding is ejected certain distance, product and regrinding-material stick together, need the artificial mouth of a river of shearing, but shear in the process of the mouth of a river artificial, product can occur and be cut manyly, perhaps therefore the mouth of a river situation of not cutting away fully can cause waste on producing.
Summary of the invention:
In view of the deficiency that above-mentioned prior art exists, the object of the present invention is to provide a kind of a kind of sprue mold insert structure that can make things convenient for the cut-out cast gate.
For achieving the above object, the present invention proposes following technical scheme:
The present invention is a kind of sprue mold insert structure, at cylinder passage is set, and passage is connected with mould gate, and to advance the gate end opening little, and an other end opening is large.
Technique effect of the present invention is, after present technique was improved, product can be talked about production automatically, thereby deducts the action at the manual repair mouth of a river, reduces manually, and easily automatic mass cuts the waste thereby reach, and reduces the beneficial effect of enterprise's production cost.
Description of drawings:
Fig. 1 is structural representation of the present invention.
Below in conjunction with embodiment the present invention is explained.
The specific embodiment:
As shown in Figure 1, the present invention is a kind of sprue mold insert structure, at cylinder passage 1 is set, and passage is connected with mould gate, and to advance gate end 2 openings little, and an other end opening is large.
When producing, the present invention is connected between injection machine cast gate and the converted products, be in the junction of converted products and cast gate, after the product injection moulding is complete, when the product of processing and injection machine cast gate are ejected, sprue mold insert structure of the present invention is motionless, product and the injection machine cast gate of processing are all ejected by thimble, and the injection machine thimble is because just in the advancing by the gate end of sprue mold insert structure, when ejecting, cut off advancing gate end, thereby reach the effect at the mouth of a river of automatic cut-out converted products.Openings of sizes is different between two openings of sprue mold insert structure channel, has the angle transition, and when guaranteeing that the product of processing is ejected, the mouth of a river of converted products also is ejected easily, and through practice, the optimum size of angle is 30 degree.
Preferred scheme, the sprue mold insert structure channel is positioned at the cylinder top.
Certainly above-described embodiment only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the people who is familiar with technique can understand content of the present invention and according to this enforcement, can not limit protection scope of the present invention with this.The all Spirit Essence of main technical schemes is done according to the present invention equivalent transformation or modification all should be encompassed within protection scope of the present invention.
