Technical Field

[0001] This utility model relates to the field of rust removal technology for mold surfaces, and in particular to a rust removal device for metal mold surfaces. Background Technology

[0002] During long-term use and storage, metal molds are prone to rust due to factors such as environmental humidity and corrosive substances in the air. This rust not only affects the appearance quality of the mold, but also reduces its precision and service life, leading to defects in the produced products and even serious problems such as mold damage. Therefore, effective rust removal treatment of metal mold surfaces is a key step in ensuring mold performance and extending its service life.

[0003] Rust removal on metal mold surfaces mainly employs chemical immersion and ultrasonic cleaning. While existing ultrasonic cleaning machines can remove rust from the mold surface through vibration, they cannot clean some crevices in the mold thoroughly, and the wastewater generated cannot be recycled, resulting in resource waste. Therefore, improvements are needed to address these issues. Utility Model Content

A butterfly valve is installed on the tube body of the L-shaped tube 7 located on the outer wall of the ultrasonic cleaner 1, and a U-shaped tube is connected to one end of the flange of the L-shaped tube 7. 8. A slag discharge hole is provided at the bottom of the inner wall of the U-shaped tube 8.

Multiple waterproof rings are fixedly connected to the inner wall of the external threaded interface. A plug extending into the external threaded interface is fixedly connected to the screw-on cap 9. Both the L-shaped tube 7 and the U-shaped tube 8 are made of PVC material, which is lightweight and corrosion-resistant.

Through the cooperation of the L-shaped tube 7, the U-shaped tube 8, the butterfly valve, and the screw-on cap 9, it is convenient to discharge and filter wastewater, which improves the convenience of wastewater treatment and enables preliminary purification of wastewater.

[0020] In this invention, a C-shaped tube is screwed onto one end of a U-shaped tube 8, and a one-way valve 10 is fixedly connected to one end of the C-shaped tube. An internally threaded cylinder is fixedly connected to the outer wall of the one-way valve 10, and a connecting pipe is screwed onto the internally threaded cylinder.

[0021] Working Principle: In using this invention, firstly, the operator places the horizontal plate 3 into the first overlapping groove at the top of the cleaning tank 2 using the handle frame. The metal mold to be derusted is then placed on the perforated plate 4. The screw 5 is adjusted so that the pressure plate at the bottom of the n-shaped frame presses down on the mold. The self-locking nut 6 is tightened, and locking washers enhance the locking effect. Anti-slip rubber pads prevent the mold from sliding, achieving stable fixation of the mold. Next, an appropriate amount of rust-removing liquid is injected into the cleaning tank 2, and the ultrasonic cleaner 1 is started. Its internal ultrasonic transducer generates ultrasonic waves, which act on the mold surface through the rust-removing liquid. Ultrasonic vibration removes surface rust. The perforated plate 4 does not obstruct the propagation of ultrasonic waves, ensuring uniform rust removal. During the rust removal process, if it is necessary to clean the mold... To remove rust from the crevices, the water pump at the top of water tank 11 is activated to draw clean water from tank 11 through a memory metal flexible hose 12. The hose's duckbill-shaped end is used to rinse the mold crevices. The rinsed wastewater flows into the rinsing tank and then into the cleaning tank 2 through the inclined drainage channel. After rust removal, the butterfly valve on the L-shaped pipe 7 is opened, and the wastewater in the cleaning tank 2 flows into the U-shaped pipe 8 through the L-shaped pipe 7. The wastewater settles in the U-shaped pipe 8, and the rust settles to the bottom. The slag discharge hole can be periodically opened and the screw cap 9 can be opened for cleaning. The waterproof ring and the plug ensure the slag discharge hole is sealed. The filtered wastewater flows back to water tank 11 through the C-shaped pipe, the one-way valve 10, and the connecting pipe, realizing wastewater recycling and reuse. The one-way valve 10 prevents wastewater backflow. At this point, the device is in use.
