Description

Technical Field

[0001] This utility model relates to a bedding product, and more particularly to a spring pillow and its molding die. Background Technology

[0002] As a core component of bedding, the pillow's function is to provide effective support for the head and neck, ensuring the user's comfort and healthy sleeping posture. Spring pillows are a type of pillow; traditional spring pillows, due to their design structure, cannot adequately conform to and support the body's physiological curves.

[0003] Furthermore, the production of foam pillows typically requires the use of specific molds for overall processing. However, due to the limitations of the mold's structural design, these pillows often cannot be formed in one step and must be manufactured in stages. Specifically, the main structure of the pillow must first be formed in the mold, with a dedicated installation opening provided. Then, operators must insert the cushioning spring assembly into the pillow's internal cavity through this opening, complete the assembly, and finally seal the installation opening. This multi-step process involves several independent procedures, making it quite cumbersome, reducing production efficiency, and causing problems for manufacturers. Utility Model Content
