Forming equipment for engineering plastic processing

Abstract

The invention discloses forming equipment for engineering plastic processing. A machine body is included, the machine body is provided with a feeding part, a heating part, a forming part, a cooling and curing part and a wide-opening discharging pipe which are connected in sequence, and a pipe opening of the wide-opening discharging pipe is connected with a material receiving barrel. A waste gas purification device with a gas inlet communicating with the forming part, the cooling and curing part and the wide-opening discharging pipe is mounted on the machine body. An air curtain channel communicating with an exhaust port of the waste gas purification device is formed in the pipe wall of the wide-opening discharging pipe, and the gas inlet of the waste gas purification device communicates with the wide-opening discharging pipe through the heating part. The waste gas purification device forms an airflow curtain for sealing between the wide-opening discharging pipe and the material receiving barrel through the air curtain channel so as to solve the pollution problem caused by waste gas overflow; and before being absorbed and purified by the waste gas purification device, the waste gasheats raw materials through the heating part, so that energy is saved, the cooling time of a plastic workpiece in the cooling and curing part is shortened, and the processing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of engineering plastic processing, in particular to a molding device for engineering plastic processing. Background technique [0002] Engineering plastics can be used as engineering materials and a type of plastic that can replace metal manufacturing machine parts. Engineering plastics have excellent properties such as high rigidity, low creep, high mechanical strength, good heat resistance, and good electrical insulation. They can be used in harsh chemical and physical environments for a long time, and can replace metals as engineering structural materials. [0003] The processing and production process of engineering plastics generally includes processes such as mixing, melting, molding, and cooling and solidification. After mixing, the liquid phase slurry that is heated to a molten or semi-molten state is passed through extrusion molding equipment, Mold molding equipment, injection molding equipment and...
