Description

Technical Field

[0001] The utility model relates to the technical field of in-mold cutting, in particular to an in-mold cutting type forming and bending mold. Background Art

[0002] In the production process of the terminal passing through the mold, it is usually necessary to leave terminal connecting ribs to achieve the circulation effect during molding. After the mold molding is completed, the terminal needs to be demolded and taken out, and the connecting ribs of the terminal need to be trimmed by the die cutting process.

[0003] In the existing terminal production technology, when the mold is molded, the terminal connection rib is used to provide the metal liquid for circulation to achieve the effect of integrated terminal molding. As an indispensable part of the production of the terminal connection mold, the terminal connection rib is generally formed together and then the connecting part is cut by a cutting die separately. However, this method will increase the additional process and invisibly increase the cost, such as the processing cost of the cutting die and the labor cost. Moreover, the additional process will also increase the time and affect the progress. Utility Model Content
