[0002] Metal inserts are frequently used in the electronics industry. Currently, many metal inserts are made by injection molding a plastic part onto a metal sheet. The metal inserts are then made into a continuous strip and separated into individual metal inserts by cutting equipment. Because the metal inserts are relatively small, high cutting accuracy and fast cutting speed are required. Existing cutting mechanisms are complex and cannot meet production needs. Furthermore, existing cutting equipment cannot be well utilized in automated production lines for continuous operation and is not suitable for mass production. Utility Model Content

The support base 1 includes a horizontal plate 101 and a vertical plate 102. The vertical plate 102 is vertically fixed below the horizontal plate 101. The horizontal plate 101 has a concave material groove 101-1 along its transverse direction for conveying the material strip. The material groove passes through the left and right ends of the horizontal plate 101. A cutting through hole 101-2 is provided in the material groove 101-1. The upper pressure block 2 is fixed on the horizontal plate 101 and above the cutting through hole 101-2. The cutting block 3 is in the cutting through hole 101-2. The first driving member 9 is fixed on the support base 1 by a mounting bracket 8 and driven to install with the cutting block 3. The first driving member 9 drives the cutting block 3 to move up and down in the cutting through hole 101-2.

[0020] The cutting block 3 includes a base 4 and a cutting blade 5. The base 4 includes a first support platform 401 and a second support platform 402. The second support platform 402 protrudes above the first support platform 401 and has a mounting through hole for placing the cutting blade 5. The cutting blade 5 is elastically mounted in the mounting through hole along the vertical direction. Several positioning pins 7 are also installed on the second support platform 402. The bottom of the positioning pins 7 is fixedly installed to the second support platform 402, and the top of the positioning pins 7 passes through the material groove 101-1 and is inserted into the positioning hole of the material strip. A storage groove 501 is provided in the bottom of the cutting blade 5. A compression spring 11 is placed in the storage groove 501 and is compressed in the mounting through hole.
