Plastic plate extrusion die

Abstract

The invention provides a plastic plate extrusion die. The plastic plate extrusion die comprises a die body which is rotatably connected with a sealing cover plate at a discharge port, a heating mechanism and a grooving mechanism, the heating mechanism is arranged on the die body, the heating mechanism comprises side edge boxes, a top surface box, a gas guide pipe, heating pipes, a first heat conducting plate and a second heat conducting plate, the two side boxes with the same specification are fixedly mounted on the two side walls of the die body correspondingly, the heating pipes are fixedlyinstalled in the two side edge boxes, the top surface box is fixedly installed at the top of the die body, the top surface box is in communication with the side edge boxes on the two sides of the diebody through a plurality of identical gas guide pipes correspondingly, the inner walls of the corresponding die body of the side edge boxes are fixedly embedded with the first heat conducting plate, and the inner wall of the corresponding die body of the top surface box is fixedly embedded with the second heat conducting plate. The plastic plate extrusion die has the advantages of multi-surface heating and convenience in grooving of the bottom of the plastic plate.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a plastic plate extrusion mold. Background technique [0002] Extrusion die is a kind of forming die, but its discharge method is to realize the image through the action of extrusion. It is widely used in aluminum special-shaped structures, and is also used in plastic parts. At the front end of the extruder, it is used to make pipes or profiles. In short, a mold is a tool used to shape an object. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object through the change of the physical state of the formed material. The extrusion mold can be described by a metaphor: cut a crutch-shaped hole on the bottom plate of the pump, block the air outlet, and pull out the piston. , the cylinder is filled with yellow mud, and the piston is inserted into the air to "inflate", and an extruded "tri...

AI Technical Summary

Problems solved by technology

[0003] The emergence of plastic sheet extrusion dies greatly facilitates the manufacture of sheets, but the current stage of plastic sheet manufacturing equipment has many shortcomings, for example, it is not easy to process and slot the bottom of the plastic sheet during processing, and the surface of the plastic sheet is heated unevenly , leading to poor processing effect of the plate, and easy to cause uneven shape of the plate
