Die

Abstract

The invention discloses a die. A die body comprises a through pipe arranged along the axis position; the pipe comprises an opening part, a gradually-shrinking part and an extending part; the opening part is arranged on the surface of the die body and extends to one end of the pipe; the diameter of the opening part is larger than the outer diameter of a to-be-installed pipe product; the caliber of the opening part is larger than the caliber of the gradually-shrinking part; and the extending part extends from the other end of the gradually-shrinking part to the tail end of the pipe. By means of the die, the outer diameter of the pipe product is effectively prevented from abnormally deforming, the product quality is improved, the service life of the product is prolonged, and the die has the beneficial effects of being low in improvement cost, saving cost and the like.

Description

technical field [0001] The invention relates to a mold, in particular to a pipe mold. Background technique [0002] In the industry, the pipe body is mainly processed by drilling machines, lathes or other devices. The pipe body is made by removing the waste material from the center of the processing equipment to form a central control pipe body. However, when the pipe is used , often for specific needs, the inner and outer diameters of the pipes must be appropriately compressed. When the pipes are docked, or for the barrel of a toy gun, etc., the current processing method has a pipe in the mold, and the diameter of the pipe is smaller than the outer diameter of the pipe. Therefore , when the pipe is put into the mold, it will be compressed and the inner diameter of the pipe will be reduced. Since the diameter of the pipe is smaller than the outer diameter of the pipe, when the pipe is put into the pipe, it will often cause the nozzle of the pipe to be damaged by impact or pr...

Problems solved by technology

[0002] In the industry, the pipe body is mainly processed by drilling machines, lathes or other devices. The pipe body is originally a solid pipe, and the waste in the center of the processing equipment is removed to form a central control pipe body. However, when the pipe is used , often for specific needs, the inner and outer diameters of the pipes must be appropriately compressed. When the pipes are docked, or for the barrel of a toy gun, etc., the current processing method has a pipe in the mold, and the diameter of the pipe is smaller than the outer diameter of the pipe. Therefore, , when the pipe is put into the mold, it will be compressed and the inner diameter of the pipe will be reduced. Since the diameter of the pipe is smaller than the outer diameter of the pipe, when the pipe is put into the pipe, it will often cause the nozzle of the pipe to be damaged by impact or pressure. deformation, resulting in a loss of quality
