[0002] In the production process of automobile seat, circulation foaming line is a commonly used production process line, which is used to manufacture the foam part of seat. In this process, molds play a crucial role, as they determine the shape and size of the foam finished product. However, during the use of molds, demolding is a critical step. To ensure that the foam finished product can be smoothly and damage-free from the mold, a layer of mold release agent must be applied to the surface of the mold.

[0003] Traditional mold release agent application methods often rely on manual operation, which not only increases labor costs, but also has problems such as uneven application, low efficiency, and potential safety risks. Manual application cannot guarantee consistent amount and position of each application, which may affect the quality and consistency of the foam finished product. In addition, with the increasing automation of production lines, manual operation has gradually become a bottleneck for production efficiency improvement.

[0004] Therefore, there is an urgent need in the market for a device that can automatically, uniformly and efficiently apply mold release agent to the surface of the mold to meet the automation needs of modern automobile seat production lines. SUMMARY

[0005] The utility model aims at providing a kind of automatic spraying device of mould release agent for circulation foaming line, to solve the problems of traditional mold release agent application methods, which often rely on manual operation, not only increase labor costs, but also have problems such as uneven application, low efficiency and potential safety risks.
