Device for regulating flow of tube blank plastic suction mold forming runner

Abstract

The invention discloses a device for regulating flow of a tube blank plastic suction mold forming runner. The device is characterized by comprising a tube blank plastic suction mold main body (1), wherein a hollow tubular main core shaft (2) is arranged in the tube blank plastic suction mold main body (1), a plastic suction tube (3) is arranged in the main core shaft (2), and the plastic suction tube (3) is connected to the main core shaft (2) in a sleeved mode, and is arranged coaxial with the main core shaft (2); the lower end of the main core shaft (2) protrudes out of the lower end surfaceof the tube blank plastic suction mold main body (1), an inner hollow forming mouth mold (4) is fixedly connected to the lower end of the tube blank plastic suction mold main body (1), the lower endof the main core shaft (2) is connected in the forming mouth mold (4) in a sleeved mode, and an interval is arranged between the outer surface of the lower section of the main core shaft (2) and the inner surface of the forming mouth mold (4) to form the lower runner; and a drainage ring (6) is connected to the middle section of the main core shaft (2) in a sleeving mode. The device for regulatingthe flow of the tube blank plastic suction mold molding runner has the advantages that the device can overcome the defects in the prior art, and the structural design is reasonable and novel.

Description

technical field [0001] The invention relates to a device for regulating the flow rate of a flow channel in a tube embryo suction mold, which belongs to the field of plastic suction molds. Background technique [0002] Blister, also known as hollow blister, is a rapidly developing plastic processing method. The blister 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 blister molding machines, blister 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 blister include polyethylene, polyvinyl chloride, polypropylene, polyester, etc., and the resulting hollow containers are widely used as industrial packaging containers. According to the production method of the parison, blister can be divided into extrusion blister and injection bliste...
