An energy-saving and environment-friendly plastic insulation board molding device

Abstract

The invention relates to the technical field of plastic insulation boards, and discloses an energy-saving and environment-friendly molding device for plastic insulation boards, comprising a mould, the top of the mold is interspersed with a suction pipe, and the inside of the suction pipe is rotatably connected to a twisted rod , the outside of the twisted rod is provided with a suction pipe, the top of the twisted rod is fixedly connected with a central shaft, the side of the central shaft is meshed with a receiving wheel, and the side of the receiving wheel away from the central shaft is meshed and connected with a The side of the ejector rod is slidably connected with a push rod, and the side of the ejector rod away from the mercury plate is fixedly connected with a liquid pumping plate, and the side of the liquid pumping plate is slidably connected with a transition box, and the side of the transition box is There is a liquid inlet pipe fixedly connected. The energy-saving and environment-friendly plastic insulation board forming device, through the cooperation of the mercury box and the receiving wheel, can continuously squeeze the liquid plastic inside the mold during the shrinking process of the liquid plastic, preventing the shrinkage of the plastic from changing its size due to cooling. .

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...
