Description

Technical Field

[0001] The utility model is a replaceable insert for an injection molding machine, belonging to the technical field of accessories for injection molding machines. Background Art

[0002] When an injection molding machine is used for injection molding, it is usually used together with a mold. There are many types of molds. Some molds have multiple inserts fixed on the surface. Some products need to interchange inserts when designing the mold to meet different product requirements of customers. For the rapid replacement of non-appearance surface inserts, there are already mature mold structures.

[0003] Patent No.: CN208730240U, mentions a replaceable insert for an injection molding machine. In the device, the insert is made inclined on all sides, a triangular groove is processed on the bottom, and a pin hole is processed at an appropriate position to fix the insert. When replacing the insert, it is only necessary to knock the pin out from the side, and then by prying the triangular groove, the insert can be taken out and replaced with other inserts, and the pin is reinserted to complete the process. During the replacement process, the mold does not need to be removed from the machine, which improves the replacement efficiency. However, the pin is fixed in the pin hole by a slight interference fit, so it is not suitable for frequent installation and disassembly. The device uses knocking to disassemble the pin, which will reduce the positioning accuracy and the reliability of the connection, thereby affecting the installation stability of the insert and the subsequent injection molding effect. Now there is an urgent need for a replaceable insert for an injection molding machine to solve the above-mentioned problems. Utility Model Content
