Description

Technical Field

[0001] This utility model relates to the field of rubber product manufacturing technology, and in particular to a rubber product mold ejection device. Background Technology

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformations under small external forces. It can return to its original shape after the external force is removed. Rubber is divided into two types: natural rubber and synthetic rubber. Rubber products refer to various products made from natural and synthetic rubber as raw materials, and also include products made from recycled waste rubber.

[0003] Rubber products are diverse and very common in daily life and production. In the production of rubber products, injection molding is usually used to first shape the rubber. After the rubber is shaped inside the injection mold, it needs to be removed from the mold. The traditional method of removal is relatively simple, which is to manually remove the shaped rubber from the mold. However, the rubber is shaped inside the mold and has a certain degree of adhesion to the inner wall of the mold. The rubber product is easy to stick to the inside of the mold, and it is laborious and time-consuming to remove it manually, which is not very practical. Utility Model Content
