Abstract

The invention provides a pipe extrusion molding machine head. The pipe extrusion molding machine head comprises a machine head body and a perforated plate, wherein the machine head body and the perforated plate are used for being connected to an extrusion head of a screw-type extruder; a flow divider is installed in the machine head body, a core rod, a support and a flow-dividing cone are sequentially installed on the flow divider, and a mouth mold is installed on the machine head body; the core rod stretches into the mouth mold, the conical tip of the flow-dividing cone is installed towards the perforated plate, and a groove is formed in the outer wall of the core rod in the axial direction; and one end of the groove communicates with the outer end face of the core rod, and the other end of the groove communicates with the side face of the support. By forming the groove in the core rod, stiffeners are generated on the inner wall of a formed pipe, and the perforated plate is improved, so that the flow speed of a plastic fluid tends to be uniform, and the uniform thickness of the pipe wall is guaranteed during forming; and the pipe manufactured through the forming machine head is high in strength, and the thickness of the pipe wall is uniform, so that the service life of the pipe is greatly prolonged.

Description

technical field [0001] The invention relates to the field of extrusion molding, in particular to a pipe extrusion molding head. Background technique [0002] Extrusion forming, referred to as extrusion, is an important forming method for the continuous production of plastic products. It passes through a porous plate and a splitter, is divided into several strands by the splitter, and then merges, and finally enters the annular channel formed by the mandrel and the die. , to extrude continuous tubing. [0003] However, in the existing extrusion molding, the flow rate of the plastic fluid after passing through the perforated plate and the splitter is different, which finally leads to uneven density and inconsistent wall thickness of the produced pipe, and the strength of the pipe is low. Contents of the invention [0004] The technical problem to be solved by the present invention is: the thickness of the existing pipe wall is inconsistent and the density of the pipe is une...
