Abstract

The invention discloses a blow-molding machine mold head capable of manufacturing a transparent line. The mold head comprises a storage cylinder, wherein a storage core is arranged inside the storage cylinder in the axis direction; a storage space is formed between the storage core and the storage cylinder; a discharge runner is communicated between the storage space and the discharge hole of the blow-molding machine mold head; a transparent ring is formed around the discharge runner; the transparent ring comprises an annular main body part; a baffle part extends to the discharge runner from the main body part in a convex manner; a transparent plastic outlet is formed in the bottom end of the baffle part; a transparent plastic inlet which is communicated with the transparent plastic outlet is formed in the blow-molding machine mold head. Due to adoption of the transparent ring, fluid in the discharge runner can be baffled in a certain position, and transparent fluid can be filled below the baffle, so that a manufactured plastic product has stripy transparent lines, and the transparent line can be used as an observation window for observing the liquid level of a liquid inside a container. The position of the baffle part on the transparent ring can be adjusted through swinging, so that the position of the transparent line can be controlled.

Description

technical field [0001] The invention belongs to the field of hollow blow molding, in particular to a die head of a blow molding machine capable of making transparent threads. 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 transmissi...
