Abstract

The invention discloses a plastic bar hot-pressing extrusion device. The plastic bar hot-pressing extrusion device is characterized in that two connecting rods are fixedly connected to an outer ring,each clamping plate is of an arc structure, two through holes are formed in the outer ring, each connecting shaft is fixedly connected to one clamping plate, a first fixing plate and a second fixing plate penetrate through one through hole are arranged on the outer surface of the connecting shaft in a sleeving manner, connecting blocks are arranged at the two ends of the first fixing plate and thetwo ends of the second fixing plate correspondingly, and the connecting blocks on the first fixing plate are connected to the connecting blocks on the second fixing plate through bolts; the connecting shaft is pulled by screwing the bolts on the connecting blocks; and the positions of the two clamping plates are adjusted to the positions corresponding to a mouth mold, so that a plastic bar is located between the two clamping plates, a supporting effect is achieved on the plastic bar, and the plastic bar is prevented from being deformed and bent due to the influence of gravity.

Description

technical field [0001] The invention relates to the technical field of plastic product processing, in particular to a hot-press extrusion device for plastic rods. 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. But the extruding device of existing plastic bar is easily deformed and bent due to the weight of the plastic bar when discharging, which easily causes the bar to break. Content...
