Abstract
The invention discloses a single-runner round sprue which comprises a round body and a groove runner. The round body is a ladder-like cylinder, the large-diameter end serves as a head end, and the small-diameter end serves as a tail portion. A screw hole is formed in the head of the round body. The groove runner is arranged on the tail portion of the round body. The single-runner round sprue is easy to machine and form, the runner is not prone to generating lapping defects, the double runner forming rate is high, the production rate is increased, and the production cost is reduced.
Description
Technical field
The present invention relates to a kind of degree of accuracy high, it is simple to molding is difficult to the cast gate of injuring part.
Background technology
Melt through narrow and small cast gate speedup, heat, be beneficial to fill die cavity.First solidifying near closed hollow ring at cast gate after injection pressurize feeding, reduce the deformation of plastic and rupture, narrow and small cast gate is easy to plastic under condensed material in runner and is separated, and finishing is convenient.But easily producing damage moulding at lapping defect or cast gate at cast gate, so easy to process, degree of accuracy is high, it is simple to molding is difficult to the cast gate of injuring part, can improve productivity ratio, reduces production cost.
Summary of the invention
For the technical problem of above-mentioned existence, it is an object of the invention to: propose a kind of degree of accuracy high, it is simple to molding is difficult to the cast gate of injuring part.
The technical solution of the present invention is achieved in that a kind of single channel circle cast gate, comprises circular body and groove runner；Described circular body is stepped cylinder, and one end, big footpath is head, and path one end is afterbody；It is provided with screw hole on the head of described circular body；Groove runner it is provided with on the afterbody of described circular body.
Preferably, the inwall of groove runner is round and smooth inwall.
Due to the utilization of technique scheme, the present invention compared with prior art has the advantage that
A kind of single channel circle cast gate of the present invention, it is simple to processing, it is easy to molding, runner is difficult to output lapping defect, and dual channel ratio of briquetting is high, improves productivity ratio, reduces production cost.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings technical solution of the present invention is described further:
Accompanying drawing 1 is the side structure schematic diagram of a kind of single channel circle cast gate of the present invention；
Accompanying drawing 2 is the afterbody plan structure schematic diagram of a kind of single channel circle cast gate of the present invention；
Wherein: 1, circular body；2, groove runner；3, head；4, afterbody；5, screw hole.
Detailed description of the invention
The present invention is described below in conjunction with the accompanying drawings.
As accompanying drawing 1,2 show a kind of single channel circle cast gate of the present invention, comprise circular body 1 and groove runner 2；Described circular body 1 is stepped cylinder, and one end, big footpath is head 3, and path one end is afterbody 4；It is provided with screw hole 5 on the head 3 of described circular body 1；Displacement avoided by fixing cast gate；It is provided with groove runner 2 on the afterbody 4 of described circular body 1；The inwall of groove runner 2 is round and smooth inwall, it is easy to melt flows, it is to avoid produce lapping defect.
Above-described embodiment is only for technology design and the feature of the explanation present invention; its object is to allow person skilled in the art will appreciate that present disclosure and to be carried out; can not limit the scope of the invention with this; all equivalence changes made according to spirit of the invention or modification, all should contain within the scope of the present invention.
