[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figures 1 to 3 , the utility model provides a technical solution:

[0019] A punching machine for producing injection molds, comprising a workbench 1, a frame 2 installed on the workbench 1, and a chip storage box placed on one side of the workbench 1, a first electric push rod is installed on the top of the frame 2, the output shaft end of the first electric push rod passes through the frame 2 and is detachably installed with a support seat 3, a plurality of punches 4 are detachably installed below the support seat 3, limit rods 5 are symmetrically installed around the top of the workbench 1, the support seats 3 are respectively connected to the limit rods 5 by sliding sleeves, a punching seat 7 corresponding to the position of the punch 4 is placed in the middle of the workbench 1, and clamping components are provided on both sides of the punching seat 7, a recovery groove 6 is opened inside, a chip removal port is opened on one side of the recovery groove 6, and a chip removal component is installed inside.

[0020] During operation, firstly, according to the need of punching the mold workpiece, install the suitable punch 4 and punching seat 7. The punching seats 7 of different sizes can be clamped and fixed by the clamping assembly. After the installation is completed, the mold workpiece to be processed is placed on the punching seat 7. The first electric push rod drives the support seat 3 and several punches 4 to move downward for punching. The limit rod 5 plays a limiting role, which improves the stability of the punching work. The waste chips generated during the punching will fall into the recovery groove 6 through the through hole on the punching seat 7, and the waste chips will be automatically transported to the chip storage box through the internal chip removal assembly.

[0021] A limiting sleeve is provided on the top of the limiting rod 5, and the limiting sleeve, the limiting rod 5, the supporting seat 3, the output shaft end of the first electric push rod and the punch 4 are all fixed by threaded connection, which is convenient for installing and disassembling the punch 4 and the supporting seat 3.

[0022] The clamping assembly includes limit plates arranged on both sides of the punching seat 7, a screw 9 threadedly connected to the limit plates, and a clamping plate 8 connected to one end of the screw 9. By rotating the screw 9, the clamping plate 8 is driven to move to contact the two sides of the punching seat 7 to achieve the purpose of clamping and fixing.

[0023] The chip removal assembly includes a feeding screw 10 installed inside the recovery tank and a servo motor for driving the feeding screw 10 to work. The servo motor drives the feeding screw 10 to work to transport the waste chips.

[0024] An L-shaped frame 11 is installed on one side of the workbench 1, and a second electric push rod is installed on the top of the L-shaped frame 11. The output shaft end of the second electric push rod passes through the L-shaped frame 11 and is connected to the pressure plate 12. After working for a period of time, the second electric push rod can be started to drive the pressure plate 12 to move downward, squeezing the waste chips inside the chip storage box, squeezing the waste chips together, thereby expanding the storage space inside the chip storage box. It should be noted that the chip storage box is a cube or rectangular structure with an opening on the top.
