Utility model has the advantages that the utility model separates injection hole with the tip of blowing needle, circular cone is utilized
Original beveled tip is substituted, injection hole is arranged in the side of needle tubing, circular cone is conical block structure, to make to blow
The hole that needle leaves in blow mold is rounder and more smooth, avoid blowing needle easily the band from blow mold fall a part expect, from
And the material grain for avoiding generation is directly blown to workpiece surface and is sticked in workpiece wall, has been increased to the quality of product.This is practical new
The arcwall face of type can make deflector hole and needle tubing outer wall intersection rounder and more smooth, avoid deflector hole and needle tubing outer wall intersection
It is sharp it is stupefied scrape raw material, be sticked in workpiece wall so that the material grain for further avoiding generation is directly blown to workpiece surface.This reality
With the direction of the arc of novel arc shell towards the inside of needle tubing, the injection hole on arc shell can be made to be located at needle tubing deeper
Region, so that raw material is scraped into the sharp edge of injection hole is avoided, to further avoid the material grain directly quilt of generation
Workpiece surface is blown to be sticked in workpiece wall.The utility model also has compact, manufacturing cost simple for structure cheap and using easy
The advantages of.
Detailed description of the invention
Attached drawing is used to provide a further understanding of the present invention, and constitutes part of specification, practical with this
Novel embodiment is used to explain the utility model together, does not constitute limitations of the present invention.In the accompanying drawings:
Fig. 1 is the structural schematic diagram of the utility model.
Mark component: 1 screwed pipe, 2 Marking ring, 3 needle tubing, 4 injection hole, 5 arc shell, 6 deflector hole, 7 arcwall face 8 cone
9 first spherical surface of shape block, 10 second spherical surface.
Specific embodiment
It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
It is blow molded rounded tip blowing needle, as shown in Figure 1, including needle tubing 3, one end connecting screwed tube 1 of needle tubing 3, screwed pipe 1
Inside is connected to the inside of needle tubing 3, and the other end of needle tubing 3 connects circular cone 8, and circular cone 8 is conical block structure, circular cone
8 bottom surface and the end of needle tubing 3 cooperate, and the side of needle tubing 3 opens up deflector hole 6, the side week of deflector hole 6 arcwall face 7, needle tubing are arranged
Arc shell 5 is installed in 3 inside, and the direction of the arc of arc shell 5 opens up injection hole on arc shell 5 towards the inside of needle tubing 3
4.The inside of injection hole 4 is communicated with the inside of deflector hole 6.
The utility model separates injection hole with the tip of blowing needle, substitutes original beveled tip using circular cone 8, will
The side of needle tubing 3 is arranged in injection hole 4, and circular cone 8 is conical block structure, so that blowing needle be made to leave in blow mold
Hole it is rounder and more smooth, avoid blowing needle easily the band from blow mold fall a part expect, so as to avoid the material grain of generation
It is directly blown to workpiece surface to be sticked in workpiece wall, has been increased to the quality of product.The arcwall face 7 of the utility model can make to lead
Discharge orifice 6 and 3 outer wall intersection of needle tubing are rounder and more smooth, avoid the sharp of deflector hole 6 and 3 outer wall intersection of needle tubing and stupefied scrape original
Material, is sticked in workpiece wall so that the material grain for further avoiding generation is directly blown to workpiece surface.The arc of the utility model
The direction of the arc of shell 5 can make the injection hole 4 on arc shell 5 be located at the deeper region of needle tubing 3 towards the inside of needle tubing 3,
So that raw material is scraped into the sharp edge of injection hole 4 is avoided, so that the material grain for further avoiding generation is directly blown to work
Part surface is sticked in workpiece wall.
The outside of the arc shell 5 has the first spherical surface 9, and the inside of arc shell 5 has the second spherical surface 10, the first ball
Face 9 and the second spherical surface 10 are spherical, and the second spherical surface 10 constitutes a smooth curved surface with deflector hole 6.
Second spherical surface 10 and deflector hole 6 of the utility model, which constitute a smooth curved surface, can further increase deflector hole
6 and arc shell 5 at smoothness, avoid sharp edge from scraping raw material, so that the material grain for further avoiding generation is direct
Workpiece surface is blown to be sticked in workpiece wall.
