Problems solved by technology

Although the above method realizes the softening treatment of the heating material of the plastic sheet, the softening process first needs to raise the temperature of the lower mold as a whole, which increases the intermediate link, and is affected by the thermal conductivity of the lower mold, which reduces the softening of the plastic sheet to a certain extent. efficiency

Abstract

The invention discloses a novel aluminum alloy plastics-sucking mold. The plastics-sucking mold comprises an upper mold body and a lower mold body. A plastics-sucking mold cavity is formed after moldassembling. An exhaust channel and an annular water cooling structure are arranged in the upper mold body. A hot air channel structure is arranged in the lower mold body. A hot air supply device is arranged outside the lower mold body. The plastics-sucking mold cavity is formed in one side of the hot air channel, and the hot air supply device is arranged at the other end of the hot air channel. According to the novel aluminum alloy plastics-sucking mold disclosed by the invention, the plastics-sucking mold is reasonable in structure design and unique in effect, outside high-temperature hot aircan be directly guided into the plastics-sucking mold through the hot air channel structure formed in the lower mold, plastic sheets are subjected to heating and softening treatment directly, the temperature of the plastic sheets is increased rapidly, heating is more uniform, the softening efficiency of the plastic sheets is effectively improved, and the plastics-sucking quality of the plastic sheets is improved to a certain extent.

Description

technical field [0001] The invention relates to an aluminum alloy suction mold, in particular to a new type of aluminum alloy suction mold capable of rapidly heating and softening plastic sheets, belonging to the technical field of accessories for suction molding machines. Background technique [0002] The blister forming machine is also called a thermoplastic forming machine. Its working principle is: using 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. Molded into various shapes of vacuum cover, or attached to the surface of various shapes of products. The blister process can be divided into thin sheet blister and thick sheet blister according to the thickness of the sheet. [0003] The mold used in the blister molding machine is called a blister mold. It is a plastic packaging product made by heating a flat plastic sheet to soften it, and vacuuming it on the surface of the bli...
