[0007] In order to facilitate the disassembly, assembly and replacement of the upper template, as a circuit board shape punching mold of the utility model, the upper surface of the upper template is fixedly connected with a mounting seat, a positioning rod is inserted into the interior of the mounting seat, and the mounting seat and the positioning rod are connected by a locking handle.

[0008] In order to facilitate the control of the downward movement of the upper template, as a circuit board shape punching die of the utility model, the upper surface of the positioning rod is fixedly connected to a hydraulic cylinder, and the hydraulic cylinder is fixedly installed on the inner top wall of the fixed frame.

[0009] In order to facilitate the disassembly, assembly and replacement of the lower template, as a circuit board shape punching mold of the utility model, the lower surface of the lower template is fixedly connected with a positioning seat, and a positioning frame is installed inside the positioning seat. The positioning frame and the positioning seat are fixedly connected through a positioning handle, and the positioning frame is fixedly installed on the inner bottom wall of the fixed frame by bolts.

[0010] In order to make the mold more stable, as a circuit board shape punching mold of the utility model, both sides of the lower surface of the fixed frame are fixedly connected with support bases, and the number of the support bases is two.

[0011] In order to facilitate the control of the start and stop of the hydraulic cylinder, as a circuit board shape punching die of the utility model, a control switch is fixedly installed on one side of the front of the fixed frame, and the control switch is electrically connected to the hydraulic cylinder through a wire.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The circuit board shape punching die is configured through the cooperation between the lower template, the upper template, the boss, the square cutter, the tightening spring, the pressure plate, the mounting seat, the positioning rod and the hydraulic cylinder. When punching the circuit board, the staff can place multiple circuit boards on the bosses at different positions at one time, and then the staff starts the hydraulic cylinder, which can drive the upper template to move downward. During the descent, the pressure plate can first contact the circuit board to press the circuit board, and then the tightening spring continues to compress, which can move the square cutter downward, making it easier to punch the circuit board. The circuit board punching process can be made more stable and the punching accuracy can be higher. In addition, multiple circuit boards can be punched at one time, which greatly improves the punching efficiency of the circuit board. BRIEF DESCRIPTION OF THE DRAWINGS
