The utility model discloses a heat insulation and heat dissipation mold seat of a paper-
plastic forming machine, which comprises a mold seat, a first heat insulation plate, a plurality of heat insulation
layers, a second heat insulation plate, an
air chamber cover plate, a heating
air chamber plate, a third heat insulation plate and a heating plate which are sequentially connected from top to bottom, the heating
air chamber plate, the third heat insulation plate and the upper heating plate are sequentially installed on the other end face, away from the heat
insulation layer, of the second heat insulation plate, and when the device is used, the third heat insulation plate is arranged on the heating plate of a main heating component in the
hot press forming step, and the second heat insulation plate, the heat
insulation layer and the first heat insulation plate are arranged upwards in the direction of a
machine frame of a forming
machine. Therefore, the heat is effectively prevented from being transmitted to the
machine frame of the forming machine, the
thermal deformation of the machine frame is reduced, the precision of the machine frame is improved, and the yield of paper pulp molded products is improved.
