Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, in particular to a special-shaped injection-molded shell of a massage chair. Background Art

[0002] An injection mold is a tool used to produce plastic products and also to give them a complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to the process of injecting heated, molten plastic into the mold cavity under high pressure by an injection molding machine. After cooling and solidification, a molded product is obtained. Injection molds are divided into two types according to their molding characteristics: thermosetting plastic molds and thermoplastic plastic molds. As injection molds gradually take shape, the number of molds used in factories is also increasing.

[0003] The special-shaped injection-molded shell of the massage chair is a special-shaped workpiece, which is a relatively irregular workpiece. This type of workpiece needs to replace a separate mold for processing during the processing. At the same time, the scope of use of this type of workpiece is relatively fixed and generally has a stable range of use.
