Abstract

The utility model relates to a torpedo needle. The torpedo needle comprises a core umbrella head, a core rod and a fixed cover, wherein a rubber opening is formed in the center of one end of the fixed cover; an inner fixed cover cavity is formed in the center of the other end of the fixed cover and is communicated with the rubber opening through an inner cavity hole; a charging cavity is formed in the core umbrella head; the core rod is arranged at the central part of the core umbrella head; one end of the core rod is a flat head end, and the other end of the core rod is a sharp head end; the core rod extends into the inner fixed cover cavity; the flat head end is positioned inside the inner fixed cover cavity and is matched with the inner cavity hole, so that molten materials with an appropriate flow enter the rubber opening; the sharp head end penetrates through the core umbrella head and extends out of the core umbrella head; and a part on one side of the core umbrella head tightly contacts a circumferential part on one side of the inner fixed cover cavity. According to the flat head structure of the core rod, the flow of the molten materials can be effectively limited, so that the number of the molten materials at the rubber opening is decreased, the molten materials are fully cooled, and dribbling and wire-drawing are prevented.

Utility model content
The utility model object is to provide a kind of for the flow that can effectively limit fused materials on hot mouth in order to overcome the deficiencies in the prior art, prevents the torpedo pin of wire drawing.
For achieving the above object, the technical solution adopted in the utility model is: a kind of torpedo pin, comprises fuse umbrella head, fuse rod and fixed cap; Described fixed cap one end is provided with Jiao Kou in center, the outer expanding shape that described Jiao Kou is taper; Described fixed cap other end center is provided with fixed cap inner chamber; Described fixed cap inner chamber is communicated with Jiao Kou by lumen orifice; On described fuse umbrella head, be provided with feed cavity; Described fuse rod is arranged on the central part of fuse umbrella head; One end of described fuse rod is butt end, and the other end is tip end; Described fuse rod extend in fixed cap inner chamber; Described butt end is positioned at the inside of fixed cap inner chamber; Described butt end coordinates with lumen orifice, makes the fused materials of desired flow enter Jiao Kou; Described tip end passes fuse umbrella head, and stretches out outside fuse umbrella head; The circumferential location close contact of one side of described fuse umbrella head and fixed cap inner chamber one side.
Preferably, the circular area of described lumen orifice is not more than the area of the annulus at smallest passage place, the passage that the minimum fused materials that smallest passage is excellent for fuse and fixed cap inner chamber forms can circulate.
Preferably, on the excircle of described fixed cap, have thread, the thread in thread and hot mouth main body inner wall matches.
Preferably, by the draw-in groove in hot mouth main body inner wall and thread, torpedo pin is fixed in hot mouth main body.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
A kind of torpedo pin of the utility model scheme, simplicity of design, fuse rod in lumen orifice place is tack structure, can effectively limit the flow of fused materials, and the material of Jiao Kou place melting is reduced, cooling abundant, prevents from salivating wire drawing, improves the quality of product.
