[0018] The present utility model provides a stamping die for punching mold parts, including a mounting shell 1. A lower die 2 is fixedly installed at the bottom of the inner cavity of the mounting shell 1. An upper die 3 is slidably installed on the top of the lower die 2. An annular pipe 4 is fixedly installed on the surface of the mounting shell 1. A liquid storage tank 7 is arranged at the bottom of the mounting shell 1. A water pump 5 is fixedly installed on the surface of the liquid storage tank 7. A nozzle 6 is fixedly installed on the top of the annular pipe 4. A draw-out plate 8 is slidably installed at the bottom of the mounting shell 1.

[0019] Further, the input end of the water pump 5 is connected to the inside of the liquid storage tank 7, the output end of the water pump 5 is fixedly connected to the annular pipe 4, a set of spray nozzles 6 is provided, the water pump 5 can pump the coolant in the liquid storage tank 7, and then convey the coolant to the spray nozzles 6 through the annular pipe 4, and the spray nozzles 6 can spray the coolant.

[0020] Further, a protective frame 11 is fixedly connected to the top of the installation shell 1, a transparent plastic plate is fixedly installed on the protective frame 11, and the transparent plastic plate plays a role in preventing sputtering and blocking. A diversion hole 15 is penetrated and opened at the bottom of the inner cavity of the installation shell 1, and two diversion holes 15 are symmetrically arranged. A guiding slope 16 is arranged at the bottom of the inner cavity of the installation shell 1. The coolant entering the bottom of the inner cavity of the installation shell 1 can flow towards the diversion hole 15 under the guidance of the guiding slope 16, and finally pass through the diversion hole 15 and enter the liquid storage tank 7.

[0021] Further, an extension groove 12 is opened at the bottom of the installation shell 1, a through hole 13 is penetrated and opened at the top of the extension groove 12, and positioning grooves 14 are opened on the groove walls of the extension groove 12, and two positioning grooves 14 are symmetrically arranged. A filter screen 81 is fixedly installed on the pull-out plate 8, positioning strips 82 are fixedly connected to both the left and right sides of the pull-out plate 8, and a sliding guiding fit is formed between the positioning strips 82 and the positioning grooves 14. A grasping hole 83 is also opened on the pull-out plate 8. The coolant entering the punching hole of the lower die 2 can wash the debris remaining in the punching hole during the stamping process. The debris and the coolant pass through the through hole 13 downward. When the coolant passes through the filter screen 81, the debris cannot pass through the filter screen 81 and is intercepted.

The upper die 3 and the lower die 2 cooperate with each other to realize the stamping process of the fitting. During the stamping process, the water pump 5 pumps the coolant in the liquid storage tank 7, and then conveys the coolant to the spray nozzles 6 through the annular pipe 4. The spray nozzles 6 spray the coolant towards the stamping area. The coolant reduces the temperature of the fitting, the upper die 3 and the lower die 2, reduces the friction force, and prolongs the service life of the upper die 3 and the lower die 2. After the spray nozzles 6 spray the coolant, the coolant entering the bottom of the inner cavity of the installation shell 1 flows towards the diversion hole 15 under the guidance of the guiding slope 16, and passes through the diversion hole 15 and enters the liquid storage tank 7. The coolant entering the punching hole of the lower die 2 can wash the debris remaining in the punching hole during the stamping process. The debris and the coolant pass through the through hole 13 downward. When the coolant passes through the filter screen 81, the debris cannot pass through the filter screen 81 and is intercepted, and the coolant continues to flow downward and enters the liquid storage tank 7.
