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 plastic-absorbing mold. The plastic-absorbing mold comprises an upper mold body and a lower mold body. The upper mold body and the lower mold body form a plastic-absorbing mold cavity after being combined. An air exhaust channel and an annular water-cooling structure are arranged inside the upper mold body. A warm air channel structure is arranged inside the lower mold body. A warm air supply device is arranged outside the lower mold body. The plastic-absorbing mold cavity is formed in one end of the warm air channel, and the warm air supply device is arranged at the other end of the warm air channel. The novel aluminum alloy plastic-absorbing mold is reasonable in structural design and unique in effect. Due to the fact that the lower mold body is internally provided with the warm air channel structure, high-temperature hot air outside the mold can be directly guided into the plastic-absorbing mold cavity to directly heat and soften a plastic sheet, the plastic sheet is rapidly heated more uniformly, the softening efficiency of the plastic sheet is effectively improved, and the plastic-absorbing quality of the plastic sheet is improved to a certain extent.

Description

technical field [0001] The invention relates to an aluminum alloy blister mold, in particular to a novel aluminum alloy blister mold capable of rapidly heating and softening plastic sheets, and belongs to the technical field of plastic molding 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. 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 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 vacuu...
