Description

Technical Field

[0001] This utility model relates to the field of electrical terminal mold technology, specifically an electrical terminal mold. Background Technology

[0002] Traditional electrical terminal "circular piece-ring" integral parts require punching and then rolling. During rolling, if a single-operation die is used for bending in one go, the large clamping force of the ring will either damage the ring during ejection or cause interference between the ejector pin and the lower die. Furthermore, the circular piece is easily sucked into the die cavity by negative pressure, making it difficult to remove. If the circular piece could be ejected during ring separation, production efficiency would be greatly increased, and extensive research has been conducted on this. Utility Model Content

[0009] A further technical solution includes a base plate fixed to the lower side of the machine body, a second hydraulic cylinder fixed on the base plate, a push rod of the second hydraulic cylinder fixed to the moving box, and a plurality of second slide rods slidably arranged inside the base plate, the second slide rods being fixedly connected to the moving box.

[0010] In a further technical solution, a vertical guide rod is fixed to the top of the base plate, and the vertical guide rod is fixedly connected to the machine body.

[0013] The beneficial effects of this utility model are: First, this mold processes the forming part into a ring shape by bending it twice, and then uses a linkage demolding structure to push the circular part out of the machine body using the lifting plate, which is very convenient and efficient.

[0014] Second, the third forming groove is used to prevent the lifting plate from getting stuck after it moves upward, thus preventing the lifting plate from being unable to push out normally.

After the lower mold and the moving box move to the left, the lifting plate can be located in the cavity, which prevents the lifting plate from being stuck by the lower mold. This allows the lifting plate to push the circular piece normally. Furthermore, the cavity occupies a small area of ​​the lower mold, which can maintain the arc structure of the top of the lower mold. This allows the forming part to maintain its circular structure even after being bent. Since the forming part itself needs to be connected to the wire end in subsequent use, its roundness requirement is not very high. After the wire end is connected, the forming part needs to be pressed and deformed to fix it to the wire end. Therefore, this design effectively balances the final size of the product and the processing technology. Attached Figure Description
