Description

Technical Field

[0001] This utility model relates to the field of metal mold tools, and in particular to a metal mold with a self-cleaning function. Background Technology

[0002] In the metal products processing industry, metal molds are the core equipment for mass production, and their surface cleanliness directly affects product precision and pass rate. With the advancement of intelligent manufacturing, traditional manual mold cleaning methods can no longer meet the needs of efficient and precise production, and the demand for molds with self-cleaning functions is becoming increasingly urgent.

[0003] Existing metal mold cleaning methods mostly rely on manual labor or simple rinsing devices. Traditional structures typically consist of a top plate, bottom plate, upper mold, lower mold, and a simple hydraulic cylinder. During cleaning, manual spraying with a handheld nozzle is required, lacking fixed cleaning components. For example, the bidirectional nozzle lacks a fixed support frame, resulting in unstable spray angles of the cleaning fluid. Metal debris and oil stains easily remain in the corners of the mold cavity. After cleaning, there is no dedicated squeezing and drainage component, relying solely on natural air drying. Moisture remains on the mold surface for a long time, especially in the grooves of the lower mold, where water easily accumulates, leading to mold corrosion. The cleaning fluid is mostly discharged directly without a filtration and recovery structure, wasting resources and polluting the environment. The cleaning process requires manual operation after the machine is stopped, and there is no automatic cleaning linkage after the second electric push rod moves the mold, extending the production interval. Therefore, this application designs a metal mold with a self-cleaning function to solve the above problems. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model uses a water pump in conjunction with the water pipe and bidirectional nozzle of the cleaning component.

The cleaning fluid tank 9 stores the cleaning fluid, and the water pump 13 provides power to the cleaning component, facilitating the delivery of the cleaning fluid to the cleaning component and ensuring the continuous operation of the cleaning process. The cleaning component consists of a water pipe and a bidirectional nozzle 14. One end of the water pipe is fixed to the upper end of the water pump 13. A fixing plate is fixed to the side of the second electric push rod 4. A clamping ring is installed on the side of the fixing plate, and a fixing frame is provided on the side of the fixing plate. The bidirectional nozzle 14 passes through the side of the fixing frame, and the other end of the water pipe is threaded to the side of the bidirectional nozzle 14. The water pump 13 delivers the cleaning fluid to the bidirectional nozzle 14 through the water pipe. The bidirectional nozzle 14 simultaneously washes the upper mold 7 and the lower mold 8. The clamping ring and the fixing frame fix the water pipe and the nozzle, facilitating comprehensive cleaning of the mold surface and improving the cleaning effect.

[0020] In this invention, a connecting plate is fixedly connected to the lower end of the first electric push rod 3, and a water-absorbing cotton block 15 is installed at the lower end of the connecting plate. The first electric push rod 3 pushes the connecting plate downward, and the water-absorbing cotton block 15 contacts the mold surface to absorb residual moisture, facilitating rapid drying of the mold and preventing mold corrosion. A push plate is fixedly connected to the side end of the lower mold 8, and extension plates with threaded holes are fixedly connected to both sides of the lower mold 8. A second threaded rod 16 is provided on both sides of the push plate. The two second threaded rods 16 are respectively rotatably inserted into the threaded rods inside the two extension plates. A second motor 11 is provided on the side end of the placement box 6. The motor shaft of the second motor 11 is coaxially fixedly connected to one of the second threaded rods 16. A pulley is provided on the side end of both second threaded rods 16, and a belt is provided between the two pulleys. The second motor 11 drives the two second threaded rods 16 to rotate synchronously through the pulleys and belt, and the push plate drives the two second threaded rods 16 to rotate synchronously. The lower mold 8 moves along the second threaded rod 16, facilitating its transfer to the cleaning position and achieving automated transfer. The extrusion drainage assembly consists of a filter plate and a wastewater tank. A guide groove is provided on the side of the placement box 6, and a sliding block 12 is slidably provided on the side of the guide groove. The filter plate is installed on the upper end of the sliding block 12, and a water outlet pipe is provided on the lower end of the sliding block 12. A valve is provided inside the water outlet pipe.

[0021] Working principle: When using this utility model, first connect the power supply. The hydraulic cylinder drives the upper mold 7 to rise. The second motor 11 drives one of the second threaded rods 16 to rotate. Through the pulley and belt, the other second threaded rod 16 rotates synchronously, causing the push plate to move the lower mold 8 to the cleaning position. Start the water pump 13. The cleaning fluid in the cleaning fluid tank 9 is transported to the bidirectional nozzle 14 through the water pipe. The second electric push rod 4 pushes the fixing plate to adjust the position of the bidirectional nozzle 14. The bidirectional nozzle 14 rinses the mold. The cleaning wastewater falls into the interior of the lower mold 8. After rinsing, the push plate moves the lower mold 8 to the lower end of the absorbent cotton block 15 in the placement box 6. The first electric push rod 3 moves the connecting plate down. The process begins with the absorbent cotton block 15 absorbing residual moisture from the mold surface. Then, the first electric push rod 3 moves the connecting plate upwards, while the first motor 5 drives the first threaded rod 10 to rotate, causing the sliding block 12 to move along the guide groove to the lower end of the absorbent cotton block 15. The first electric push rod 3 then moves the connecting plate downwards, and the absorbent cotton block 15, by squeezing the filter plate, stores the filtered wastewater inside the sliding block 12. Next, the first motor 5 drives the first threaded rod 10 to rotate, causing the sliding block 12 to move along the guide groove, and the filtered wastewater is discharged into the wastewater tank through the outlet pipe. After cleaning and drying, the second motor 11 reverses to reset the lower mold 8, and the hydraulic cylinder drives the upper mold 7 to reset, completing the entire self-cleaning process.
