Novel mould structure

Abstract

The invention discloses a novel mould structure. A mould body comprises a through pipeline which is arranged along a shaft center position; the pipeline comprises an opening part, a gradual reducing part and an extending part; the opening part is arranged on the surface of the mould body; the opening part extends towards one end of the pipeline; the diameter of the opening part is greater than the outer diameter of a to-be-mounted tube; opening part aperture of the opening part is greater than aperture of the gradual reducing part; and the extending part extends to the tail end of the pipeline from the other end of the gradual reducing part. According to the novel mould structure disclosed by the invention, the outer diameter of the tube is effectively prevented from generating abnormal deformation, product quality is improved, and service life of a product is prolonged, so that the novel mould structure has beneficial effects of low modifying cost, cost saving, 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...

[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
