Problems solved by technology

In short, a mold is a tool used to shape an article. This tool is composed of various parts. Different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. Plastic The appearance of sheet extrusion dies has greatly facilitated the manufacture of sheets, but there are many deficiencies in the current stage of plastic sheet manufacturing equipment. The flat phenomenon, and the heating efficiency and cooling efficiency are low, which makes the whole processing efficiency low

Abstract

The invention discloses a plastic plate extrusion die, and belongs to the technical field of plastic plate dies, the plastic plate extrusion die comprises a die body, first heating plates are arranged in the upper wall and the lower wall of the die body, and second heating plates are arranged on the two side walls of the die body; a plastic solution in the mold body is directly heated through the first heating plate and the second heating plate, meanwhile, heat formed by the second heating plate is dissipated into the second shell and can also be transmitted into the first shell through the air pipe, and the heating and heat preservation effects of the mold are improved; a plastic plate in the mold body is heated more uniformly through multi-face heating, the heating efficiency is improved, during cooling, a sliding plate is opened, a sealing plate and a first sealing cover are opened for cooling, an exhaust fan is started for air exhaust, air flow passes through an air pipe from the interior of a second shell and then goes out from a second frame plate, the air flow flows from the second shell, and the cooling efficiency is improved. And the periphery of the mold body is cooled, and the cooling effect is improved.

Description

technical field [0001] The invention belongs to the technical field of plastic sheet moulds, in particular to a plastic sheet extrusion mould. Background technique [0002] The extrusion die is a kind of forming die, but its discharging 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 item. This tool is composed of various parts. Different molds are composed of different parts. It mainly realizes the processing of the shape of the item by changing the physical state of the molded material. The appearance of sheet extrusion dies has greatly facilitated the manufacture of sheets, but the current stage of plastic sheet manufacturing equipment has many shortcomings. The phenomenon of flattening, and the heating efficiency and cooling efficiency are low, so t...
