A bottled drinking water plastic barrel blow molding device

Abstract

The invention relates to the field of blow molding, and discloses a bottled drinking water plastic bucket blow molding device, which includes a fixed frame, the fixed frame is a Z-shaped bracket, and the front of the fixed frame is equipped with a blow molding barrel through a telescopic device. The plastic mold is a cylindrical hollow barrel, the top of the blow mold is provided with a circular top opening, the center of the top plate of the fixed frame is fixed vertically downward with a fixed rod, and the lower end of the fixed rod is fixed with a fixed sleeve , the fixed sleeve is a circular sleeve, and the lower end of the fixed sleeve is snapped vertically downward to connect with an air intake pipe, and the air intake pipe is a circular hollow long pipe, and the air intake pipe is plugged into the blow molding pipe through the top port. The inside of the mold. In the present invention, when the inner ring slides through the spiral groove, it will drive the entire rotating head to move downward on the air intake pipe, and the rotating head will drive the air outlet pipe to rotate and discharge air. At this time, the six groups of air outlet pipes can evenly blow the blow molding raw materials. , so that the blow molding material can receive the blowing of the air evenly.

Description

technical field [0001] The invention relates to the field of blow molding, in particular to a blow molding device for barreled drinking water plastic barrels. Background technique [0002] Blow molding, also known as hollow blow molding, is a rapidly developing plastic processing method. The blow molding process began to be used to produce low-density polyethylene vials during World War II. In the late 1950s, with the birth of high-density polyethylene and the development of blow molding machines, blow molding technology has been widely used. The volume of the hollow container can reach thousands of liters, and some production has adopted computer control. Plastics suitable for blow molding include polyethylene, polyvinyl chloride, polypropylene, polyester, etc., and the resulting hollow containers are widely used as industrial packaging containers. According to the parison production method, blow molding can be divided into extrusion blow molding and injection blow moldi...
