Problems solved by technology

[0002] At present, when producing PVC pipes, the pipe-making mold sleeves of PVC pipes include mold sleeves and mold cores. During the pipe-making process, when each PVC pipe is produced, some PVC materials will remain in the mold sleeves and mold cores. If the outlet of the pipe is not cleaned in time, the surface of the PVC pipe behind will be uneven, which will affect the quality of the product

Abstract

The invention relates to a pipe-making die sleeve which comprises a die sleeve and a die core, wherein the inner wall of one end of a pipe orifice of the die sleeve is provided with a first circular notch, the outer wall of one end of a pipe orifice of the die core is provided with a second circular notch, and gaskets made of polytetrafluoroethylene are respectively arranged in the first circular notch and the second circular notch. The pipe-making die sleeve disclosed by the invention has the advantages that because the circular notches are symmetrically formed in the same ends of the die sleeve and the die core, and the gaskets made of polytetrafluoroethylene are respectively arranged in the circular notches, in the process of production, no PVC material remains at the outlets of the die sleeve and the die core. The pipe-making die sleeve is a new technical proposal, and is convenient to popularize and use.

Description

technical field [0001] The invention relates to the field of pipe materials, in particular to a pipe-making mold cover. Background technique [0002] At present, when producing PVC pipes, the pipe-making mold sleeves of PVC pipes include mold sleeves and mold cores. During the pipe-making process, when each PVC pipe is produced, some PVC materials will remain in the mold sleeves and mold cores. If the outlet of the PVC pipe is not cleaned in time, the surface of the PVC pipe behind will be uneven, which will affect the quality of the product. Contents of the invention [0003] In view of the above-mentioned shortcomings, the object of the present invention is to provide a pipe-making mold sleeve that does not leave PVC material at the outlet of the mold sleeve and the mold core. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a pipe-making mold cover according to the present invention, comprising a mold cover and ...
