Abstract

The invention discloses a novel aluminium alloy plastics suction mould which comprises an upper mould part and a lower mould part; after the upper mould part and the lower mould part are assembled, a plastics suction mould cavity is formed; the upper mould part is internally provided with an air exhaust channel; the air exhaust channel consists of a main channel and auxiliary channels; the main channel is formed above the auxiliary channels and stretches out of the upper portion of the upper mould part; and the auxiliary channels are formed below the main channel and dispersed in an umbrella-shaped manner, and stretch out of an inner cavity of the upper mould part. The novel aluminium alloy plastics suction mould is unique in structural design; the air exhaust channel formed in the upper mould part of the blister mould is distributed in an umbrella-shaped manner from the top down, so that differential pressure of various air exhaust points can be balanced effectively with the structural design; a plastics suction molding process can be more stable; and the surface quality and the molding precision of a plastics suction product are improved.

Description

technical field [0001] The invention relates to a plastic-absorbing mold, in particular to a novel aluminum alloy plastic-absorbing mold with a smooth molding process and high-precision plastic-absorbing products, and belongs to the technical field of plastic-absorbing forming machine accessories. Background technique [0002] Blister molding machine is also called thermoplastic molding machine. Its working principle is: use the vacuum suction generated by the vacuum pump to heat and soften thermoplastic plastic sheets such as PVC, PET, PETG, APTT, PP, PE, PS, etc., through the mold suction. It can be molded into vacuum covers of various shapes, or attached to the surface of products of various shapes. [0003] The mold used on the blister forming machine is called a blister mold, which heats a flat plastic sheet to soften it, then absorbs it on the surface of the blister mold by vacuum, and forms a plastic packaging product after cooling. The current blister molds can be d...
