Abstract
The utility model provides a thermal contraction thin pipe extruding mould, which is characterized in that the utility model is composed of a module body, bolts and a pinhead; the pinhead is arranged in the module body, and is tightly propped and fixed by the bolts. The thermal contraction thin pipe extruding mould does not need jointing, and the intensity and the rigidity are good. The pinhead is not easy to be inflected under the action of material stream when the utility model is used for extruding production, the thickness of extruded pipe wall is symmetrical, and the extruding finished product rate of a thermal contraction thin pipe can be increased.
Description
[technical field]
The utility model relates to the heat-shrinkable tube manufacturing, relates in particular to the field of extruding of making the thermal contraction tubule.
[technical background]
At present, known thermal contraction tubule extrusion die is made of fine steel tube and die body, fine steel tube is packed in the hole of die body, is fixed together by brazing, during welding, fine steel tube produces annealing under high temperature action, intensity and rigidity obviously reduce, extrude when producing, under the effect of materials flow, fine steel tube bends easily, causes the wall unevenness of extruding pipe even, do not reach the requirement of extruding of thermal contraction tubule, produce a large amount of waste products.
[summary of the invention]
The purpose of this utility model provides a kind of thermal contraction tubule extrusion die, and the intensity of this mould and good rigidly are extruded when producing, and under the effect of materials flow, syringe needle is not easy to bend, and the thickness of pipe wall of extruding is even.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of thermal contraction tubule extrusion die is characterized in that: it is by die body, and screw and syringe needle constitute, and syringe needle is contained in the die body, is held out against fixing by screw.
Described a kind of thermal contraction tubule extrusion die, it is characterized in that: described die body is made by metal material.
Described a kind of thermal contraction tubule extrusion die is characterized in that: described screw is the soket head cap screw of a centre bore to be arranged or be the fluting holding screw.
Described a kind of thermal contraction tubule extrusion die is characterized in that: described syringe needle is medical needle or is syringe needle for animals.
The syringe needle and the die body of this thermal contraction tubule extrusion die are as a whole, and syringe needle is stiff in die body, do not need welding, the intensity of syringe needle and good rigidly.
The invention has the beneficial effects as follows: this thermal contraction tubule extrusion die does not need welding, and intensity and good rigidly are extruded when producing, under the effect of materials flow, syringe needle is not easy to bend, and the thickness of pipe wall of extruding is even, can improve the yield rate of extruding of thermal contraction tubule.
[description of drawings]
Fig. 1 is a structure principle chart of the present utility model.
1. syringe needles among the figure, 2. screw, 3. die body.
[specific embodiment]
In Fig. 1, syringe needle (1) is No. 7 medical needles, and screw (2) is a soket head cap screw, and center-hole diameter is φ 3, and die body (3) is made by the Cr12 material.Syringe needle (1) is contained in the die body (3), is held out against fixingly by screw (2), and syringe needle (1) and die body (3) form an integral body, and syringe needle (1) is stiff in die body (3).
Claims (4)
1. thermal contraction tubule extrusion die is characterized in that: it is by die body, and screw and syringe needle constitute, and syringe needle is contained in the die body, is held out against fixing by screw.
