Communication pipe processing die and processing technology thereof

Abstract

The invention relates to a communication pipe processing die and a processing technology thereof, and aims to solve the technical problem that the thickness of the pipe material is easy to be uneven during the processing of the existing communication pipe product, and the overall assembly and fixing of the die is difficult to be stable. The main point is that an extrusion screw of the processing die comprises a discharge inner core and a feed split screw; the discharge inner core passes through the discharge inner core by a connecting rod at one side of a discharge chamber and is integrally connected with a feed split screw; an annular bulging transition cavity and an outer wall corresponding to the annular bulge are formed on the inner wall at the joint of a floating discharge ring, a sealing ring at the rear end of an adjusting core and a screw outer cavity; a splitting hole between the feeding splitting screw and the inner diameter of the outer cavity of the screw is positioned at astep on the joint of a ring opening section of the feeding splitting screw and a screw section, and a spiral diversion groove of the outer diameter of the screw section communicates with the splitting hole; during processing, the raw material of particles is squeezed by a spiral diversion groove on the outer wall of the feeding splitting screw, and flows to a discharge chamber under the action ofthe pressing force, and is buffered into the discharge chamber through a transition cavity.

Description

technical field [0001] The invention relates to the processing of pipes, in particular to a mold for processing communication pipes and a processing technology thereof. Background technique [0002] Pipe refers to the material used to make pipe fittings. Communication pipes are generally made of plastic and processed by extrusion molding. The processing mainly involves and uses pipe extrusion molds. This type of mold and processing mechanism is disclosed in the Chinese patent literature with the application number 201620213496.5, the date of authorization announcement is 2016.07.27, and the name of the utility model is "wall thickness adjustment mechanism for roller tube body forming"; the extrusion mold includes a tube body, The extrusion screw and the extrusion cavity that accommodates the forming material of the idler tube body, the extrusion cavity is provided with a ring-shaped inner boss; the shaping sleeve includes the sleeve rod connected to the extrusion screw, and ...
