Background technology
TOP-TIP is the important component part in injection mold production equipment, utilizes heating and temperature controlled principle, makes the flow path portion of mould keep molten condition, is accompanied by the development of die industry, and TOP-TIP is also growing.The torpedo pin using on hot mouth in TOP-TIP at present, as shown in Figure 1, comprises fuse umbrella head 1, fuse rod 2 and fixed cap 4; Described fixed cap 4 one end are provided with glue mouth 5 in center, described glue mouth 5 is the outer expanding shape of taper; Described fixed cap 4 other end centers are provided with fixed cap inner chamber 6; Described fixed cap inner chamber 6 is communicated with glue mouth 5 by lumen orifice 7; On described fuse umbrella head 1, be provided with feed cavity 3; Described fuse rod 2 is arranged on the central part of fuse umbrella head 1; The two ends of described fuse rod 2 are tip; Described fuse rod 2 one tip ends extend in fixed cap inner chamber 6; A described other tip end passes fuse umbrella head 1, 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.What its fuse rod 2 its one end near lumen orifice were tip is coniform, this prong structure can not limit the flow of the fused materials at lumen orifice place effectively, cause at Jiao Kou place material more, cooling down high-temperature fused materials fully, cause salivation wire drawing, affect product quality.
Summary of the invention
Technical problem for above-mentioned existence, the object of the invention is: proposed a kind ofly for the flow that can effectively limit fused materials on hot mouth, prevented the torpedo pin of wire drawing.
Technical solution of the present invention is achieved in that 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, and smallest passage is the passage that the fused materials of fuse rod and the formed minimum of fixed cap inner chamber 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 present invention compared with prior art has following advantages:
A kind of torpedo pin of the present invention, 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.
