Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a swing-arm type foaming clamp locking mechanism. Background Art

[0002] During the production process of foam parts, raw materials and additives are placed in a mold to react and form foam parts. In the existing technology, the lower mold is a movable mold, and a lifting mechanism is used to push the movable mold up to the fixed mold for mold closing. The lifting mechanism uses a threaded screw, hydraulic mechanism or cylinder.

[0003] During the polyurethane foaming process, tension will be generated, which will exert downward pressure on the movable mold. As the equipment ages, the foaming tension in the mold will cause slight wear on the rising mechanism, resulting in stroke deviation, and causing slight dynamic errors in mold closing, which will change or even reduce the product production quality. Therefore, we need to provide a swing-arm foaming clamp locking mechanism to support the movable mold. Utility Model Content
