Polymer mould pressing foaming device assisted by supercritical fluid

The utility model provides a polymer mould pressing foaming device assisted by supercritical fluid. The polymer mould pressing foaming device comprises a supercritical fluid conveying system, a mould system, a temperature measuring device, a pressure measuring device, a pressure releasing device, a displaying and controlling system and the like, wherein the supercritical fluid conveying system, the temperature measuring device, the pressure measuring device and the pressure releasing device are respectively connected with the mould system; the mould system is heated by an upper hot plate and a lower hot plate of a mould press. According to the mould pressing foaming device, the supercritical fluid has super-high infiltrability and diffusivity, so that, at a certain temperature and under the action of pressure, the supercritical fluid gradually diffuses into polymer basal bodies; then the pressure is quickly released, so as to obtain foam material with a certain shape.
