Description

Technical Field

[0001] The utility model relates to the technical field of milk bottle blow molding production, in particular to a milk bottle blow molding device. Background Art

[0002] Bottle blow molding is a type of plastic blow molding bottle. Plastic blow molding is also called hollow blow molding. The tubular plastic preform obtained by extrusion or injection molding of thermoplastic resin is placed in a split mold while hot (or heated to a softened state). After the mold is closed, compressed air is immediately introduced into the preform to inflate the plastic preform and cling to the inner wall of the mold. After cooling and demolding, various hollow products are obtained. Plastics suitable for blow molding include polyethylene, polyvinyl chloride, polypropylene, polyester, etc. The resulting hollow containers are widely used as industrial packaging containers. According to the preform production method, blow molding can be divided into extrusion blow molding and injection blow molding. The newly developed ones are multi-layer blow molding and stretch blow molding.

[0003] In most existing baby bottle blow molding processes, the blow-molded baby bottles are placed for cooling by natural cooling and then demolded. The natural cooling efficiency is low, and during the blow mold closing process, the blow mold needs to be manually positioned, which reduces production efficiency. It is necessary to design a baby bottle blow molding device to solve the above-mentioned problems. Utility Model Content
