Abstract

The invention relates to the field of blow molding, and discloses a blow molding device of a plastic bucket for barreled drinking water. The blow molding device comprises a fixed frame, wherein the fixed frame is a Z-shaped bracket, a blow molding barrel is installed on the front surface of the fixed frame by virtue of a telescopic device, a blowing mold is a cylindrical hollow barrel, a round topopening is formed in the top end of the blowing mold, a fixed rod is perpendicularly and fixedly installed in the center of a flat plate on the top end of the fixed frame downwards, a fixed sleeve isfixedly installed on the lower end of the fixed rod, the fixed sleeve is round, an air inlet pipe is perpendicularly connected to the lower end of the fixed sleeve downwards in a buckling mode, the air inlet pipe is a round hollow long pipe, and the air inlet pipe is inserted into the blowing mold through the top opening. According to the blow molding device, the whole rotary head can be driven to move up and down on the air inlet pipe when an inner ring slides through a spiral groove, air outlet pipes are driven to rotate to emit air by the rotary head, and blow molding can be performed on blow molding raw materials by six groups of air outlet pipes at the moment, so that the blow molding raw materials can be uniformly blown by air.

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...
