In the figure: 1. a mold main body; 2. a copper bar channel; 21. positioning the mold cavity; 22. shaping the die cavity; 210. positioning a first groove; 211. positioning a second groove; 212. and (6) positioning a groove III.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The structure of the copper bar finished product shaping mold provided by the embodiment is shown in fig. 1-4, and comprises a mold main body 1, wherein the mold main body 1 is axially provided with a copper bar channel 2, the copper bar channel 2 is an integral groove, a copper bar is drawn through the copper bar channel 2, the copper bar channel 2 comprises a positioning mold cavity 21 and a shaping mold cavity 22, the copper bar is shaped after being positioned and determined, the copper bar positioned by the positioning mold cavity 21 forms a copper material with uniformly distributed pressure before entering the shaping mold cavity 22, the abrasion to the shaping mold cavity 22 is reduced, the precision of the copper bar extruded by the shaping mold cavity 22 meets the requirement, and the product quality is favorably ensured;

the positioning die cavity 21 comprises a first positioning groove 210, a second positioning groove 211 and a third positioning groove 212, the notch of the first positioning groove 210 is reduced in diameter from outside to inside along the axial direction, the notch of the second positioning groove 211 is reduced in diameter from outside to inside along the axial direction, the diameter of the second positioning groove 211 is smaller than that of the first positioning groove 210, the notches of the third positioning groove 212 are the same in axial diameter, a copper bar sequentially passes through the positioning die cavity 21 with changed diameters to reduce vibration and shake, the center line of a copper bar channel 2 can be conveniently and quickly aligned, the pressure of the copper bar can be uniformly distributed, the positioning die cavity 21 is connected with the shaping die cavity 22 through the third positioning groove 212, the diameter of the shaping die cavity 22 is smaller than that of the third positioning groove 212, the end face, connected with the shaping die cavity 22, of the third positioning groove 212 is an inclined face, the copper bar positioned by the positioning die cavity 21 forms copper materials with uniformly distributed pressure before entering the shaping die cavity 22, and abrasion to the shaping die cavity 22 is reduced.

The working principle is as follows: the copper bar is drawn through integrative groove copper bar passageway 2, utilizes location die cavity 21 location, and the copper bar just forms pressure evenly distributed's copper material before getting into design die cavity 22, reduces the wearing and tearing to design die cavity 22, prolongs the life of mould main part 1 for the copper bar precision that design die cavity 22 was extruded meets the requirements, does benefit to assurance product quality.
