Description

Technical Field

[0001] The present application relates to the technical field of molding machinery, and in particular to an injection stretch blow molding stretching device. Background Art

[0002] Injection stretch blow molding is a plastic processing technology used to produce hollow plastic products such as bottles, containers, etc. This technology combines the three main steps of injection molding, stretching and blow molding.

[0003] First, the molten plastic is injected into the mold by an injection molding machine to form a preform (also called a parison) with features such as a bottom and neck. This step ensures the initial shape and dimensional accuracy of the product.

[0004] Next is the stretching stage, where the preform is heated to a suitable stretching temperature and then placed in a stretching mold. Under the action of the stretching force, the preform is stretched longitudinally, thereby increasing its length and reducing the wall thickness, improving the strength and rigidity of the product.

[0005] The last stage is the blow molding. After the stretching is completed, the stretched preform is placed in the blow molding mold and blown to fit the inner wall of the mold to form the final shape of the hollow product.

[0006] However, in the above technology, the plastic needs to be kept at a relatively high temperature both in the initial molding stage and in the subsequent stretching and blow molding stages. In addition, the plastic is constantly transported and moved during the work process. The workers at the workstations may collide with the plastic if they are not careful, which not only causes damage to the product but also causes harm to the health of the workers.
