Description

Technical Field

[0001] The utility model relates to an interchangeable insert disassembly and assembly mechanism for a mould, belonging to the technical field of mould processing. Background Art

[0002] When manufacturing products through mold processing, usually one set of molds is used to process one product. Some products have multiple different models, and the products of each model often have different local product features. In order to improve the utilization rate of the mold, when processing multiple products with different local product features, interchangeable inserts are used in the mold production process, and interchangeable inserts are replaced to achieve a set of molds that can interchangeably produce different products. For example, the bottom plate of the outer box of an air-conditioning cabinet, but because the product features of the products of different models are located on the appearance surface, that is, the surface of the interchangeable insert is the product appearance molding surface, in order to prevent damage to the integrity and aesthetics of the product appearance molding surface, the mounting screws on the interchangeable insert must be installed and fixed from the bottom surface of the mold. Then, when disassembling and replacing the interchangeable insert, it is necessary to lift the large and heavy mold to disassemble and install the mounting screws on the bottom surface of the mold to complete the disassembly and replacement of the interchangeable insert. The disassembly and assembly process of the above-mentioned interchangeable insert is very troublesome, requiring a lot of manpower and time costs, slow replacement speed, and low processing efficiency.

After the insert body is squeezed out by the insert pin, the insert body can be directly disassembled from the molding surface of the mold without moving the mold body. The insert body is convenient and quick to use and replace, saving disassembly and assembly time and production cost. The insertion bevel and the squeezing bevel are in close contact with each other, so as to fix the insert body and prevent the insert body from loosening during the production process. The pressure plate is used to fix the insert pin in the mold body, and the anti-rotation plane and the positioning plane are set to prevent the insert pin from rotating relative to the mold, thereby preventing the insert body from being loosened during installation and affecting normal production.
