[0030] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] See Figure 1 , Figure 2 , Figure 3 and Figure 4This utility model provides a cooling device for diamond cutting tools, comprising:

[0032] Mold base 1, the mold base 1 is equipped with a cooling mechanism. It should be noted that the cooling mechanism can efficiently cool the formed diamond cutting head, and the diamond cutting head can be easily removed after cooling.

[0033] The cooling mechanism includes a water tank 1 (2), a cooling channel 3, a water tank 2 (6), a return pipe 8, a connecting pipe 9, a heat dissipation pipe 10, a cooling fan 11, and an ejector assembly;

[0034] Water tank 1 2 is fixedly installed at the bottom of mold base 1, cooling channel 3 is opened on mold base 1, water tank 2 6 is fixedly installed at the top of water tank 1 2, return pipe 8 is fixedly installed on mold base 1 and water tank 2 6, connecting pipe 9 is fixedly connected to return pipe 8 and heat dissipation pipe 10, and cooling fan 11 is fixedly installed on mold base 1.

[0035] The ejection assembly includes an ejection rod 12, a float plate 13, and a guide tube 18. The bottom of the ejection rod 12 is fixedly connected to the float plate 13, and the guide tube 18 is fixedly installed on water tank 12 and water tank 26. It should be noted that the buoyancy force on the float plate 13 is greater than the weight of the diamond cutter head.

[0036] With the above structure, when the water flows in the cooling channel 3, it can carry away the heat on the diamond cutting head. Then, it enters the water tank 6 through the heat dissipation pipe 10. During this process, the cooling fan 11 is activated and blows towards the heat dissipation pipe 10 to quickly dissipate the heat in the water. In this way, the diamond cutting head can be cooled down quickly. Afterward, the water flows into the water tank 2 through the conduit 18.

[0037] Specifically, the cooling mechanism also includes a pump body 4, a water supply pipe 5, and a water extraction pipe 7. The pump body 4 is fixedly installed on the mold base 1. The pump body 4 is fixedly connected to the water supply pipe 5 and the water extraction pipe 7. The water supply pipe 5 is fixedly installed on the mold base 1, and the water extraction pipe 7 is fixedly installed on the water tank 2.

[0038] With the above structure, the pump body 4 is started and the water pipe 7 can draw out the clean water in the water tank 2. Then, the clean water is introduced into the cooling channel 3 through the water supply pipe 5. When it is necessary to remove the cooled diamond cutter head, the solenoid valve is closed, so that the clean water accumulates in the water tank 6. As the water level rises, the float 13 can move upward. The float 13 drives the ejector rod 12 to move upward. The ejector rod 12 can push the diamond cutter head upward, thus making it easy to eject the diamond cutter head.

[0039] Specifically, a solenoid valve is installed on the conduit 18. It should be noted that the solenoid valve is closed when the diamond cutter head needs to be removed.

[0040] Specifically, a baffle 14 is fixedly installed inside the second water tank 6, the bottom of the float 13 is in contact with the baffle 14, and the push rod 12 is vertically slidably installed on the second water tank 6. It should be noted that the float 13 can be limited.

[0041] Specifically, the water supply pipe 5 is connected to the interior of the cooling channel 3, and the return pipe 8 is connected to the interior of the cooling channel 3. It should be noted that this is to facilitate the flow of clean water.

[0042] Specifically, a diamond cutting head forming groove 15 is provided on the mold base 1, and a hydraulic cylinder 16 is fixedly installed on the mold base 1. The hydraulic rod of the hydraulic cylinder 16 is fixedly connected to the upper mold 17. The top of the ejector rod 12 is on the same horizontal straight line as the bottom inner wall of the diamond cutting head forming groove 15. It should be noted that this makes it convenient to form and process the diamond cutting head.

[0043] Specifically, the cooling fan 11 is located behind the heat pipe 10, which is to facilitate the cooling of the water inside the heat pipe 10.

[0044] Working principle:

[0045] S1: After the diamond cutting head is hot-pressed in the diamond cutting head forming groove 15 of the mold base 1, the pump body 4 is started; the pump body 4 draws clean water from the water tank 2 through the water pumping pipe 7, and the drawn clean water is introduced into the cooling channel 3 in the mold base 1 through the water supply pipe 5; since the water supply pipe 5 is connected to the interior of the cooling channel 3, the clean water can flow smoothly into the cooling channel 3; in the cooling channel 3, the flowing clean water comes into close contact with the diamond cutting head with a high temperature after hot pressing, and carries away a large amount of heat on the diamond cutting head through heat transfer, thus achieving the initial cooling of the diamond cutting head; after absorbing heat, the temperature of the clean water rises, and it continues to flow along the cooling channel 3, and finally flows out through the return pipe 8; since the return pipe 8 is also connected to the interior of the cooling channel 3, the clean water can flow smoothly into the return pipe 8.

[0046] S2: Hot water flowing out from return pipe 8 enters heat dissipation pipe 10 through connecting pipe 9; at this time, cooling fan 11 is started. Since cooling fan 11 is located behind heat dissipation pipe 10, the air blown out by it can quickly remove the heat of hot water in heat dissipation pipe 10, accelerating the cooling of hot water; after heat dissipation treatment, the temperature of the clean water is significantly reduced and flows into water tank 2 6. The clean water in water tank 2 6 flows back to water tank 1 2 through conduit 18, completing a complete clean water circulation cooling process; during normal cooling circulation, the solenoid valve on conduit 18 is in the open state to ensure that the clean water can flow back smoothly;

[0047] S3: After the diamond cutting head has cooled down, it needs to be removed. At this time, close the solenoid valve on the conduit 18 to prevent the clean water in water tank 2 6 from flowing back to water tank 1 2. Continue to start the pump body 4. Clean water continuously flows from water tank 1 2 through the water supply pipe 5, cooling channel 3, return pipe 8, and connecting pipe 9 into the heat dissipation pipe 10, and then flows into water tank 2 6. As clean water continues to flow into water tank 2 6, the water level in water tank 2 6 gradually rises. Since the buoyancy of the float plate 13 is greater than the weight of the diamond cutting head, and the bottom of the float plate 13 is in contact with the baffle 14 in water tank 2 6, the baffle 14 limits the float plate 13. As the water level rises, the float plate 13 moves upward under the action of buoyancy.

[0048] S4: When the float 13 moves upward, it drives the ejector rod 12, which is fixedly connected to it, to move upward together. Because the top of the ejector rod 12 is on the same horizontal line as the bottom inner wall of the diamond cutter head forming groove 15, the ejector rod 12 can push the diamond cutter head located in the diamond cutter head forming groove 15 upward, so that it can be removed from the forming groove, making it convenient for the operator to take out the diamond cutter head.

[0049] The present invention provides a detailed description of a cooling device for diamond cutting tools. Specific embodiments have been used to illustrate the principle and implementation of the present invention. These embodiments are merely illustrative and are intended to aid in understanding the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
