[0033] It should be noted that the loading platform 6 slides forward and backward by rotating the motor 8, making loading safer and more convenient. At the same time, the material is positioned by sliding the positioning plate 11 forward and backward and the slider 13 left and right, making stamping more precise.

[0034] In this embodiment, the first box body 5 is open at the top and consists of two left and right chambers. Grooves 1 are provided on both left and right sides of the right chamber, and scale lines distributed front and back are provided on the left end surface of the left chamber.

[0035] It should be noted that the scale lines are provided to make positioning more accurate, and the positioning function and the loading function are divided into two chambers so that they will not interfere with each other during work.

[0036] In this embodiment, the front end of the screw rod 7 is inserted into the first box body 5 , and the rear end passes through the first box body 5 and is fixedly installed with the motor 8 . Bearings are provided at the joints between the screw rod 7 and the first box body 5 .

[0037] It should be noted that the provision of the bearing makes the screw 7 rotate more easily, thereby improving work efficiency.

[0038] In this embodiment, there are clamping blocks on the left and right sides of the bottom of the loading platform 6. The clamping blocks are clamped with the first box body 5 through groove 1 and can slide relatively. The screw 7 passes through the loading platform 6 and is threadedly connected to the loading platform 6. A plurality of mounting holes 1 are opened on the upper surface of the loading platform 6. The mold 9 is installed on the loading platform 6 through the mounting hole 1.
