Description

Technical Field

[0001] This utility model relates to the field of foam mold technology, specifically to a molding mold for a foam headrest. Background Technology

[0002] Foam headrests are a common type of headrest, and their manufacturing process and characteristics give them a competitive edge in the market. Low cost, simple manufacturing process, and inexpensive materials result in relatively low production costs. At the same time, these headrests have a relatively long lifespan; the foaming process creates a dense molecular structure, providing good elasticity and stability, making them less prone to deformation, aging, and softening. Furthermore, ordinary foam headrests typically undergo surface finishing, resulting in an attractive appearance, soft feel, and high comfort.

[0003] A search of existing technology revealed a "foamed headrest mold" with publication number "CN207696899U". This device uses alloy tool steel for the upper and lower cutting edge frames instead of the original aluminum alloy frames, offering better wear resistance, stronger sealing after mold closing, preventing foam material leakage, and ensuring the mold does not experience product defects due to cutting edge deformation during long-term use. However, during the mold opening and closing process, the headrest, formed during use, will move upwards with the upper mold, causing it to fall under gravity. This can lead to dirt accumulation on the headrest surface, affecting the product qualification rate.

[0004] Based on this, the present invention designs a molding die for a foam headrest to solve the above problems. Utility Model Content
