Description

Technical Field

[0001] The utility model relates to the technical field of terminal production, and more specifically, to a precision molding die for terminal production. Background Art

[0002] Terminals are the breaking points of wired connections. In electrical engineering, terminals mostly refer to wiring terminals, also called wiring terminals. They are divided into single-hole, double-hole, socket, hook, etc., and are divided into materials such as silver-plated copper, zinc-plated copper, copper, aluminum, iron, etc. Their main function is to transmit electrical signals or conduct electricity.

[0003] At present, the terminal production molds on the market are usually processed by die-casting cutting. Most of the die-casting cutting devices include a cutting upper plate and a cutting bottom plate. The shapes of the cutting upper plate and the cutting bottom plate are adapted. The cutting upper plate is driven downward by a cylinder to die-cast and cut the terminal mold on the cutting bottom plate, thereby accurately cutting the mold shapes of the cutting upper plate and the cutting bottom plate.

[0004] However, the existing die-casting cutting device cannot cut multiple sets of terminal molds at the same time, and during the cutting process, the upper and lower positioning is easily inaccurate, resulting in the cutting position deviation, causing the shape of the produced terminals to fail to meet production requirements, a high defective rate, and waste of metal materials. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a precision molding die for terminal production that can accurately position and produce multiple groups of terminals by one die-casting and cutting.

[0013] By adopting the above technical solution, the cooperation between the supporting plate and the limit bolt improves the flexibility of the device. The supporting plate can move on the limit bolt, which is convenient for replacing the supporting plate and the mold block.
