The round package bucket blowing mould is even in wall thickness and free of flashes and does not need post-processing, the bottom is free of splicing joints, strength and production efficiency are high, and a product is convenient to take out.

Description

technical field [0001] The invention relates to the technical field of mold equipment, in particular to a round packaging barrel blow mold. 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 molding, and the new...
