Abstract

The invention relates to a shaping device and a manufacturing method for a plastic board. The shaping device for the plastic board comprises a first-stage feeding mechanism, a first-stage extrusion apparatus, a second-stage feeding mechanism, a second-stage extrusion apparatus, an output apparatus, a first heating apparatus, and a motor. According to the manufacturing method involved in the invention, a thermal plastic sheet or a heated plastic sheet is extruded through the first-stage feeding mechanism and the second-stage feeding mechanism so as to form a workpiece, which is subjected to positive-negative pressure molding and then to thermal extrusion to form a hollow structure. New workpieces are combined to both sides of the shaped workpiece with a hollow structure so as to form a whole. The shaping device and the manufacturing method for the plastic board disclosed by the invention have the advantages of simple technological steps, reliable and efficient processing, can produce various kinds of plastic boards, enrich the product variety and meets the demands of people while improving the production efficiency.

Description

technical field [0001] The invention belongs to the technical field of plastic plate forming, and in particular relates to a plastic plate forming device and a manufacturing method thereof. Background technique [0002] Plastic plate is a new type of composite material based on thermoplastics. It has light weight, low thermal conductivity, good heat insulation performance, can absorb impact load, has excellent cushioning performance, good sound insulation performance, and high specific strength. It is widely used in the fields of building insulation, cushioning packaging, shock resistance and sound absorption. [0003] The mold for pressing plastic sheets with a flat press is usually made of cold-rolled sheets, manganese sheets and other materials. After being heated, these materials will warp and deform due to uneven heating. Fortunately, the pressure of hot pressing and cold pressing (usually All above the pressure of 300 tons / m2) to restore the mold deformation, so as to...
