Description

Technical Field

[0001] The utility model relates to the technical field of blow molding, in particular to a novel blow needle rack structure which can move quickly. Background Art

[0002] Extrusion blow molding is a method for manufacturing hollow thermoplastic parts. Well-known blow molding objects include bottles, barrels, cans, boxes and all containers for packaging food, beverages, cosmetics, medicines and daily necessities. Large blow-molded containers are usually used for packaging chemical products, lubricants and bulk materials. Other blow-molded products include balls, bellows and toys. For the automotive industry, fuel tanks, car shock absorbers, seat backs, center brackets, and armrest and headrest covers are blow-molded. For the machinery and furniture manufacturing industries, blow-molded parts include shells, door frames, brackets, pots or boxes with an open face. The blow molding machine is a device used in the blow molding process. The blow molding machine is a device that makes plastic granules into hollow containers through the blow molding process. The blow needle holder is used to fix the blow needle on the blowing station.

[0003] At present, when the traditional blow needle rack is used to install the mold on the blow molding equipment, the blow needle rack needs to be adjusted left and right. When installing the mold, the blow needle rack needs to be moved to one side first, and then the mold is installed. After installation, the blow needle rack is moved back to the initial position and then repositioned. The existing structure for adjusting the movement of the blow needle rack requires manual climbing to the top of the machine, loosening the nut and turning the screw to achieve the left and right movement of the blow needle rack, which is inconvenient to use and has low adjustment efficiency, which affects the production, processing and use of the equipment and has relatively poor practicality.
