DETAILED DESCRIPTION

[0024] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0025] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0026] like Figures 1 to 3 As shown, a new type of mold ultrasonic cleaning machine includes a frame 3, a cleaning tank 13, a mold basket 14, an ultrasonic generator, a transducer, a controller, a control panel 17 and a power supply; the cleaning tank 13 is set inside the frame 3, the cleaning tank 13 contains cleaning liquid, and the mold basket 14 is set inside the cleaning tank 13; the transducer 23 is set inside the cleaning tank 13, and the control panel 17 is set on the outer wall of the frame 3, and the control panel 17 is connected to the controller; the power supply supplies power to the ultrasonic generator, transducer 23, and control panel 16;

[0027] The ultrasonic generator includes a positive electrode 10 and a negative electrode 18, the positive electrode 10 is located in the middle of the cleaning tank 13, and the negative electrodes 18 are symmetrically arranged on both sides of the positive electrode 10; a mounting rod 16 is set on the top of the cleaning tank 13, and the mounting rod 16 spans the opposite sides of the cleaning tank 13; the mold basket 14 includes a side rail 21, a bottom rail 22, a frame rod 20 and a handle 12, the side rail 21 is arranged around the side of the bottom rail 22 to form a accommodating cavity for placing the mold, and the bottom rail 22 is located above the bottom plate of the cleaning tank 13 and is spaced apart from the bottom plate of the cleaning tank; the top of the side rail 21 is connected to the frame rod 20, and the frame rod 20 is mounted on the mounting rod 16. The frame rod 20 is provided with a handle 12, and the handle 12 protrudes above the mold basket; the transducer 23 is set in the cleaning tank 13, and is used to convert the supersonic electrical energy generated by the ultrasonic generator into high-frequency mechanical oscillations.

[0028] As one preferred embodiment of the present invention, the cleaning tank contains an electrolytic mold cleaning liquid, wherein the mold-specific cleaning liquid comprises a neutral electrolyte. The ultrasonic generator generates an ultrasonic electrical signal exceeding 40 kHz. The transducer converts the ultrasonic electrical energy generated by the ultrasonic generator into high-frequency mechanical oscillations, which are then transmitted into the cleaning liquid, thereby achieving ultrasonic cleaning.

[0029] This utility model discloses a novel ultrasonic mold cleaning machine. Its operating principle is as follows: an ultrasonic generator generates supersonic electrical energy exceeding 40 kHz, which is converted by a transducer into high-frequency mechanical oscillations and transmitted into the cleaning fluid. Ultrasonic waves radiate forward in the cleaning fluid in alternating patterns, causing the liquid to flow and continuously generating tens of thousands of tiny bubbles. These bubbles form and grow in the negative pressure zone of the longitudinal propagation of the ultrasonic wave, and rapidly close in the positive pressure zone. This formation and rapid closure of tiny bubbles is known as cavitation. During cavitation, when bubbles close, a transient high pressure exceeding 1000 atmospheres is generated. This continuously generated transient high pressure continuously bombards the mold surface, rapidly removing dirt from the mold and crevices.

[0030] The utility model discloses a novel ultrasonic cleaning machine for molds. When in use, the mold is placed in a cleaning tank 13, and a staff inputs a control instruction through a control panel 17. The controller operates an ultrasonic generator and a transducer 23 according to the control instruction, thereby realizing automatic cleaning of the mold. The bottom rail 22 is located above the bottom plate of the cleaning tank 13 and is spaced apart from the bottom plate of the cleaning tank, so that the mold is suspended in the cleaning liquid, which can fully clean the mold and is conducive to fully removing dirt and sundries on the surface of the mold; and can also remove residual resin on the mold; through the vibration of the ultrasonic wave, the dirt is peeled off and floated, and the metal is attached to the cathode, so that the dirt in the dead corner of the mold can be removed, and the mold with complex shapes can be removed.

[0031] like Figure 4 As shown, the cleaning tank 13 is further provided with a filter 7, which includes an inlet 24, an outlet 25, a filter cartridge 27 and a filter element 26. The cleaning liquid in the cleaning tank 13 is circulated and filtered through the filter 7.

[0032] like Figure 2 As shown, it also includes a water inlet valve 4 and a circulation pump 8. A water inlet pipe 6 and a circulation pipe are set at the bottom of the cleaning tank 13. The water inlet pipe is provided with a water inlet valve 4, and the circulation pipe is provided with a circulation pump 8. When the water inlet valve 4 and the circulation pump 8 are opened, the cleaning liquid in the cleaning tank 13 can be circulated.

[0033] To further improve the cleaning effect, the cleaning liquid is a neutral electrolyte, and the positive electrode 10 and the negative electrode 18 are immersed in the cleaning liquid at a distance of 30 mm to 50 mm from the liquid surface. The liquid surface of the cleaning liquid is 100 mm to 120 mm from the top surface of the cleaning tank 13, and the positive electrode 10 and the negative electrode 18 are 50 mm to 80 mm away from the mold.

[0034] like Figure 1 and Figure 2 As shown, casters 5 are provided at the bottom of the frame 3, and push handles 9 are provided on the outer side wall of the frame. The mold ultrasonic cleaning machine can be moved to the vicinity of the mold for on-site cleaning, reducing mold transportation.

[0035] like Figure 2 As shown, the power supply includes an external power cord, and a winding shaft 18 for receiving the power cord is provided on the outer side wall of the frame 3.

[0036] like Figure 1 and Figure 2 As shown, the machine also includes a cylinder head 1, which covers the cleaning tank and is connected to the frame 3 via a hinge 2. The cylinder head 1 prevents foreign matter from falling into the cleaning tank. A support rod 11 can be provided at the bottom of the cylinder head 1 to support the cylinder head 1 and facilitate the placement of the mold in the mold basket 14.

[0037] The frame 3, the cleaning tank 13 and the mold basket 14 are made of stainless steel, which has the advantages of acid resistance and alkali resistance.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
