The invention belongs to the technical field of plastic
vacuum forming machines, and particularly relates to a separated type automatic plastic
vacuum forming machine which comprises plastic
vacuum forming equipment, the plastic vacuum forming equipment comprises a
workbench, an air cylinder is fixedly connected to the bottom of the
workbench, a feeding frame is fixedly connected to the top of the
workbench, and a heating plate is fixedly connected to the side wall of the feeding frame. When the mold reaches a preset position, the bottom of the
sponge is in contact with the top of the plate, the built-in air suction pump is started and adsorbs the plate to the surface of the mold, the
sponge continuously extrudes downwards, excessive flowing of materials is limited through elastic counter-acting force, and the stretching degree of each area is balanced; and secondly, a layer of air film can be formed between the
sponge and the plate through air injection operation,
friction force is reduced through the air
lubrication effect, the sponge and the plate are smoothly separated, the surface of the plate can be further protected, physical damage can be further reduced, and therefore the product quality can be improved.
