Description

Technical Field

[0001] The present application relates to the field of foam sponge processing, and in particular to a foam sponge molding device. Background Art

[0002] Foam sponge is a sponge material that has been specially treated to produce a pore structure. It is usually made of materials such as polymers or rubber. By adding a foaming agent and performing appropriate heating or pressure treatment, it forms many small bubbles, thus forming a sponge-like structure.

[0003] When the foam sponge is injected into the molding equipment for shaping, kraft paper needs to be laid inside the shaping equipment. However, the existing kraft paper is generally laid directly inside the molding equipment. When the foam sponge is injected, it may drive the kraft paper to move along the inside of the molding equipment, thereby causing certain wrinkles in the kraft paper, making the foam sponge after shaping uneven as a whole, reducing the overall processing efficiency of the foam sponge.

[0004] In view of the above-mentioned related technologies, the inventor believes that there is a defect that the kraft paper will be wrinkled when the foam sponge is shaped inside the molding equipment. Therefore, a foam sponge molding equipment is proposed to solve the above problem. Utility Model Content
