Description

TECHNICAL FIELD

[0002] Injection molding machine demolding equipment is the vital component in injection molding production, it is responsible for the plastic product from mold after injection molding is taken out smoothly.

[0003] In the actual use process of injection molding machine, when mechanical demolding system is used, the formed article needs a period of time to cool after injection molding is completed. This is because the high-temperature plastic has not completely solidified in the mold, and if demolding is performed at this time, it may cause product deformation, damage or poor demolding. Therefore, the formed article must be cooled to a certain extent before demolding operation is performed using the mechanical demolding system. This process increases the production cycle and reduces the production efficiency.

[0004] The temperature of the mold is often high during production. This is mainly due to the heat transfer of the plastic melt during injection molding and the possible heat source inside the mold. The high-temperature environment limits the cooling effect, slowing down the cooling speed of the mold and further prolonging the production cycle.

The high-temperature environment may cause thermal expansion, wear or deformation of the components in the mechanical demolding system, affecting its precision and stability. Long-term work in high-temperature environment may also accelerate the aging of lubricating oil and seals in the mechanical demolding system, leading to a decrease in system performance and even failure.
