Description

Technical Field

[0001] The utility model relates to the technical field of blow molding machines, in particular to a rotary conveying molding component of a blow molding machine. Background Art

[0002] Blow molding machine is a plastic processing machine. Its working principle is to use the wind force blown out by the machine to blow the plastic body to a certain shape of the mold cavity after the liquid plastic is sprayed out, so as to make the product. Blow molding is a rapidly developing plastic processing method. The tubular plastic parison obtained by extrusion or injection molding of thermoplastic resin is placed in the split mold while hot (or heated to a softened state). After the mold is closed, compressed air is immediately introduced into the parison to make the plastic parison inflate and cling to the inner wall of the mold. After cooling and demolding, various hollow products are obtained. In the existing blow molding process, telescopic parts are mostly used to drive the mold to move at the molding site. Blow molding is carried out at the extruder for heating raw materials and the blow molding site. After the blow molding is completed, the parts stick to the molding site, which is not conducive to the removal of the molded product and has a poor effect on the transfer of the product.
