[0032] The mold-removing assembly 7 is used for demoulding the insulation board after forming, and is installed on the movable mold plate 4.

[0033] It should be noted that: when in use, the movable template 4 is pushed close to the fixed template 2 by the electric rod 1 3 for mold closing, and then the liquid plastic extrusion tube is connected to the guide nozzle 64, and the liquid plastic is introduced into the feed tube 61, and then the servo motor 63 is started to drive the spiral conveying rod 62 to rotate, so as to introduce the liquid plastic in the feed tube 61 into the molding cavity 201 until the injection molding is completed. When the injection molding is completed and the mold needs to be demolded, the electric rod 1 3 is controlled to drive the movable template 4 to separate from the fixed template 2, and the electric rod 2 51 is synchronously started to drive the electric heating layer plate 52 and the stainless steel bottom plate 53 to push out the insulation plate in the molding cavity 201.
