Device for regulating flow channel flow of tube blank vacuum forming mold

Abstract

The invention discloses a device for regulating flow channel flow of a tube blank vacuum forming mold. The device is characterized by comprising a tube blank vacuum forming mold body (1), wherein a hollow tubular main mandrel (2) is arranged in the tube blank vacuum forming mold body (1), a vacuum forming pipe (3) is arranged in the main mandrel (2), the vacuum forming pipe (3) is sleeved in the main mandrel (2) and are coaxially arranged with the main mandrel (2), the lower end of the main mandrel (2) protrudes out the lower surface of the tube blank vacuum forming mold body (1), the lower end of the tube blank vacuum forming mold body (1) is fixedly connected with an inner hollow forming mold (4), the lower end of the main mandrel (2) is sleeved in the forming mold (4), a lower runner arranged at intervals is formed between the outer surface of the lower section of the main mandrel (2) and the inner surface of the forming mold (4), the middle section of the main mandrel (2) is sleeved with a drainage ring (6). The device has the advantages that the defects of the prior art can be overcome, 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...

AI Technical Summary

Problems solved by technology

When medical ampoules are produced using blister molds, due to the uneven flow rate and insufficient fusion of the molten material entering the blister mold, multiple weld lines will be formed on the surface of the finished ampoule bottle, which affects the production quality of the ampoule bottle
