Foam blow-molding machine and micro-foaming hollow molding method thereof

Abstract

The invention relates to a foam blow-molding machine and a micro-foaming hollow molding method thereof. The foam blow-molding machine comprises an automatic material suction machine, an extruder, a gas inflating device and a blow molding machine, wherein the extruder comprises a hopper, a feeding seat, a charging barrel and a screw; the hopper is fixedly connected one end of the charging barrel bythe feeding seat; the automatic material suction machine is in communication with the hopper; the screw is arranged in the charging barrel and driven by a motor; the outer side of the charging barrelis wrapped with an electric heating sheet; the end, away from an automatic suction molding machine, of the screw is further provided with a gas inflating hole; the gas inflating device is fixedly mounted on one side of the blow molding machine and communicates with the gas inflating hole; the blow molding machine comprises a material storage type mold head, a mold and a mold driving unit; the material storage type mold head communicates with the other end of the charging barrel; the mold is driven by the mold driving unit to perform mold closing and opening; and the mold closing position of the mold is directly located under the material storage type mold head. The foam blow-molding machine and the micro-foaming hollow molding method of the invention have high production efficiency; and aproduced product has good quality and the effects of sound insulation, electric insulation and heat preservation.

Description

technical field [0001] The invention relates to a blow molding machine, in particular to a foaming blow molding machine and a micro-foaming hollow molding method thereof. Background technique [0002] The blow molding machine is a machine that sprays liquid plastic and uses the wind blown out of the machine to blow the plastic body into a mold cavity of a certain shape to make a product. The plastic is melted and extruded quantitatively in the screw extruder, and then shaped through the mouth film, and then cooled by the wind ring, and then pulled by a tractor at a certain speed, and wound into a roll by a winding machine. [0003] Existing blow molding machines usually produce hard products that cannot meet the needs of products in certain fields, and ordinary PE plastics produced by blow molding machines have excellent quality, sound insulation, insulation, heat preservation, energy saving and emission reduction, etc. Larger flaws.
