Plastic rod hot pressing extrusion device and hot pressing extrusion method thereof

Abstract

The invention relates to a hot-pressing extrusion device for plastic rods and a hot-pressing extrusion method of the hot-pressing extrusion device, and solves the problems that the conventional rod extrusion device has low production efficiency and the like. The hot-pressing extrusion device comprises a rack, wherein a hot pressing pipe which is horizontally arranged and provided with a hot pressing channel is arranged on the rack, the hot pressing pipe is connected with an extrusion head, a heating mechanism is arranged on each of the hot pressing pipe and the extrusion head, a feed channel communicated with the hot pressing channel is formed in one end of the extrusion head, a plurality of discharge channels which are communicated with the feed channel respectively and allow output of finished rod products are formed in the other end, a rod support mechanism is arranged on the rack, and a rod clamping mechanism is arranged between the discharge channels and the rod support mechanism. The hot-pressing extrusion device for the plastic rods and the hot-pressing extrusion method of the hot-pressing extrusion device have the advantages as follows: the production efficiency is high, multiple rods can be produced once, discharge is uniform, the density of the rods is uniform, the rods are not prone to bending deformation in a conveying process, and the conveying speed is constant.

Description

technical field [0001] The invention belongs to the technical field of plastic product processing, and in particular relates to a hot-press extrusion device for plastic rods and a hot-press extrusion method thereof. Background technique [0002] Plastic rods generally refer to solid cylinders. Here, we also refer to solid squares, rhombuses and triangles as rods. Plastic rods are mainly used to process plastic gears, bolts, bearings and pads on metal cutting machine tools like round steel. The plastics used for extruding rods include: polyamide, polyoxymethylene, polycarbonate, ABS, polyphenylene oxide, polysulfone, polyethylene, polypropylene, polyvinyl chloride and plexiglass. At present, the processing and production of plastic rods mostly rely on hot extrusion molding, that is, the raw materials are melted at high temperature and then extruded. However, there are many deficiencies in the existing extrusion devices for plastic rods, for example, low production efficienc...

AI Technical Summary

Problems solved by technology

The above scheme solves the problem of poor discharge of the existing rod extrusion device to a certain extent, but the solution still exists: complex structure, low production efficiency, only one rod can be produced at a time, poor stability, and the discharge Due to its own weight, it is easy to deform and bend
