Energy-saving and environment-friendly plastic heat-insulating board forming device

Abstract

The invention relates to the technical field of plastic heat preserving boards and discloses an energy-saving and environment-friendly plastic heat-insulating board forming device which comprises a mold. A liquid drawing pipe is arranged on the top of the mold in a penetrating and inserting manner. A winching rod is connected into the liquid drawing pipe in a rotating manner. A liquid drawing pipeis arranged on the outer side of the winching rod. A middle shaft is fixedly connected to the top of the winching rod. A receiving wheel is connected to the side face of the middle shaft in an engaged manner. A screw rod is connected to one side, away from the middle shaft, of the receiving wheel in an engaged manner. A pushing rod is connected to the side face of an ejector rod in a sliding manner. A liquid drawing plate is fixedly connected to one side, away from a mercury plate, of the ejector rod. A transition box is connected to the side face of the liquid drawing plate in a sliding manner. A liquid input pipe is fixedly connected to the side face of the transition box. According to the energy-saving and environment-friendly plastic heat-insulating board forming device, by means of cooperative use of a mercury box and the receiving wheel, thus the effect that in the liquid plastic shrinkage process, liquid plastic in the mold is extruded continuously, and change of the size of plastic due to cooling shrinkage is prevented can be achieved.

Description

technical field [0001] The invention relates to the technical field of plastic insulation boards, in particular to an energy-saving and environment-friendly plastic insulation board forming device. Background technique [0002] Plastic insulation board, also known as polystyrene insulation board, is made of polystyrene resin supplemented by polymer heating and mixing, injecting a catalyst, and then extruding a new type of rigid new environmental protection and energy-saving foam plastic board with continuous closed-cell foaming. Its interior is an independent closed cell structure, which is a kind of thermal insulation material with excellent performances such as high pressure resistance, low water absorption, moisture resistance, airtightness, light weight, corrosion resistance, aging resistance, and low thermal conductivity. [0003] In the process of plastic insulation board processing, it is necessary to pump liquid plastic into the mold. When the liquid plastic is coole...
