Abstract

The invention relates to a forming mold of a corrugated pipe and particularly relates to a pipe blank forming mold structure of a single-wall corrugated pipe. The pipe blank forming mold structure comprises a mold body formed by connecting a top head, an opening mold and a mandril, wherein the front end of the top head is fixedly connected with a porous plate and a groove is formed in the rear end of the top head; the opening mold is connected with the top head by the match of a locking nut; a flow distribution cone is arranged at the connection part of the top head and the opening mold; an adjusting screw is arranged at the top of the flow distribution cone; the lower end of the flow distribution cone is connected with an air inlet pipeline for connecting the flow distribution cone with the mold body; the air inlet pipeline is provided with a switching valve; a through hole is formed in the center of the mandril; and an air block pull rod is arranged in the through hole. The pipe blank forming mold structure of the single-wall corrugated pipe is simple and long in service life, and has very good popularization.

Description

technical field [0001] The invention relates to a forming die for corrugated pipes, in particular to a pipe blank forming die structure for single-wall corrugated pipes. Background technique [0002] The inner and outer surfaces of the single-wall corrugated pipe are corrugated. Although its bendability and flexibility are excellent, its fluid resistance is large, and it is easy to cause the deposition of suspended solids in the groove of the inner surface. The corrugation forming device is mainly composed of a forming mold, a transmission system and a control system. Among them, the forming mold is composed of dozens of pairs of continuous blow molds split up and down, and the upper and lower molds are respectively fixed on two transmission belts in a crawler type. When the transmission system drives the mold to rotate, the upper and lower molds repeat the closing-opening action. The mold is closed to form the forming cavity of the circular pipe, and the mold is opened af...
