Description

Technical Field

[0001] The present application relates to the technical field of foam material isolation tooling, and in particular to a reusable foam material isolation fixing tooling. Background Art

[0002] Foaming materials, also known as "foaming agents" or foaming substances, refer to foaming substances that can produce bubbles without vaporizing, making them porous substances. Examples include foamed plastics, foamed rubber, foamed resins, and foamed foods. The most common of these are soft foaming materials, which are made from raw materials such as plastics (PE, EVA, etc.) and rubber (SBR, CR, etc.) with catalysts, foam stabilizers, and other auxiliary materials. Through physical foaming or cross-linking, a large number of fine bubbles appear in the plastics and rubbers, increasing their volume and reducing their density. Soft foaming materials are lightweight and flexible, and have functions such as cushioning, sound absorption, shock absorption, heat preservation, and filtration. They are widely used in industries such as electronics, home appliances, automobiles, and sports and leisure.

[0003] In the foam processing industry, to ensure that the foam forms a regular spatial pattern after expansion, fixed fixtures are often required for isolation. Currently, wooden fixtures are commonly used. Existing wooden fixtures are primarily custom-designed to specific product shapes and sizes. While they achieve isolation, the complex disassembly and reassembly process limits their reusability. Furthermore, their customizable nature limits their applicability, hindering resource conservation and environmental protection. Therefore, to address these issues, a reusable fixed fixture for foam isolation is proposed. Utility Model Content
