Abstract

The invention discloses a novel die head of a blow molding machine. The novel die head of the blow molding machine comprises a material storage cylinder, wherein the material storage cylinder is provided with a cavity with an open bottom end; a material storage core is arranged in the cavity of the material storage cylinder along an axis direction; the top end of the material storage core is fixed on the material storage cylinder; a sliding space is formed in the middle part of the material storage core along the axis direction; an adjusting rod is arranged in the sliding space in a sliding manner; the top end of the adjusting rod is fixed together with a servo cylinder; the bottom end of the adjusting rod is fixed to a die core; a lower flange is fixed to the bottom end of the material storage cylinder; a die sleeve is arranged at the bottom end of the lower flange and fixed on the lower flange by virtue of a die pressing ring; the die core is of a conical body; a discharging hole is formed between the die core and the die sleeve. The die head of the blow molding machine is simple in structure and easy to assemble and maintain.

Description

technical field [0001] The invention belongs to the field of hollow blow molding, in particular to a novel blow molding machine die head. Background technique [0002] Blow molding (blow molding), also known as hollow 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 it is hot (or heated to a softened state), and compressed air is injected into the parison immediately after the mold is closed to blow the plastic parison. It swells and clings to the inner wall of the mold, and after cooling and demoulding, various hollow products can be obtained. [0003] Extrusion blow molding machine is a combination of extruder, blow molding machine and mold clamping mechanism. It is composed of extruder, parison die head, inflation device, mold clamping mechanism, parison thickness control system and transmission mechanism. The parison die is one...
