Description

Technical Field

[0001] The utility model relates to the technical field of anti-collision devices for blow molding molds, and particularly relates to an anti-collision device for blow molding molds. Background Art

[0002] The blow molding process began to be used for producing small bottles of low-density polyethylene during World War II. In the late 1950s, with the birth of high-density polyethylene and the development of blow molding machines, the blow molding technology has been widely applied. The volume of hollow containers can reach several thousand liters, and some productions have adopted computer control. Plastics suitable for blow molding include polyethylene, polyvinyl chloride, polypropylene, polyester, etc., and the obtained hollow containers are widely used as industrial packaging containers. According to the method of making the parison, blow molding can be divided into extrusion blow molding and injection blow molding, and newly developed ones include multi-layer blow molding and stretch blow molding. Blow molding mainly refers to hollow blow molding, which is a method of blowing a hot melt parison closed in a mold to form a hollow product by means of gas pressure, and it is a plastic molding method with relatively fast development. The mold used for blow molding only has a female mold. Compared with injection molding, the equipment cost is lower, the adaptability is stronger, and it can form products with good formability and complex undulating curves. Therefore, blow molding molds play an important role in the application of the blow molding process. For example, in a Chinese utility model patent with the patent number CN218615369U, an anti-collision device for a blow molding mold is provided with a detachable anti-collision protection ring sleeved outside the mold body. The anti-collision protection ring is connected to the mold body through fixing bolts, which is convenient for disassembly and can play a role in anti-collision protection. Anti-collision protection plates are arranged around the outer wall of the anti-collision protection ring through grooves, and buffer springs are arranged between the anti-collision protection plates and the grooves. Through the cooperation of the anti-collision protection plates and the buffer springs, the effect of buffering the collision force can be effectively achieved. At the same time, a pipe joint hinge is arranged between the anti-collision protection plates and the anti-collision protection ring, and the anti-collision protection plates can be spread out at a ninety-degree angle. In this way, the anti-collision protection plates can play an anti-collision effect, and the spread anti-collision protection plates can also be used as a tool placement plate during normal use.
