Furthermore, if the dirt in the holes is not completely cleaned, the high-temperature drying process can cause it to overflow from the holes and contaminate the edges of the holes, leading to defects. Utility Model Content

[0004] The purpose of this invention is to provide a vacuum drying device with air-cutting function to solve the problems mentioned in the background art, such as the difficulty in drying residual liquid in small holes during drying, and the incomplete cleaning of dirt in the holes, which can cause contamination of the hole edges due to overflow of the high-temperature drying process.

An infrared heating tube 41 with a temperature sensor is installed inside the vacuum drying tank 4, which can detect the temperature inside the vacuum drying tank 4. A vacuum flange terminal 42 is mounted on the surface of the processing frame 2, and one end of the vacuum flange terminal 42 extends into the interior of the vacuum drying tank 4. The vacuum drying device of this utility model is also equipped with a control panel, which is used for controlling the operation of the entire device.

[0022] During implementation, the basket with the drying precision mold is placed into the air cutting groove 3 for air cutting; after air cutting, it is vacuum dried in the vacuum drying groove 4.

[0023] Furthermore, such as Figure 1 as well as Figure 4As shown, a support frame 21 is installed on the top surface of the processing frame 2. A pneumatic shielding assembly 5 is provided on the surface of the support frame 21 and above the wind cutter 3. The pneumatic shielding assembly 5 is used for shielding the wind cutter 3. The pneumatic shielding assembly 5 includes a shielding door 51 and a push-pull cylinder 52. The shielding door 51 is slidably connected to the surface of the support frame 21, and the push-pull cylinder 52 is fixedly connected to the surface of the support frame 21. The output end of the push-pull cylinder 52 is fixedly connected to the surface of the shielding door 51.

[0024] During implementation, after the basket with the drying precision mold is placed into the air cutting groove 3, the shielding door 51 is pushed by the push-pull cylinder 52 to shield the air cutting groove 3.

[0025] Furthermore, such as Figure 1 as well as Figure 4 As shown, a pneumatic sealing assembly 6 is provided on the surface of the support frame 21 and above the vacuum drying chamber 4. The pneumatic sealing assembly 6 is used for sealing the vacuum drying chamber 4. The pneumatic sealing assembly 6 includes a sealing door 61 and a pushing cylinder 62. The sealing door 61 is slidably connected to the surface of the support frame 21, and the pushing cylinder 62 is fixedly connected to the surface of the support frame 21. The output end of the pushing cylinder 62 is fixedly connected to the surface of the sealing door 61. A digital pressure gauge 60 is also installed on the surface of the sealing door 61, and the contact of the digital pressure gauge 60 penetrates through the sealing door 61. The digital pressure gauge 60 is used for pressure detection inside the vacuum drying chamber 4 after the sealing door 61 is sealed.

[0026] During implementation, a basket containing a precision drying mold is placed inside the vacuum drying chamber 4. Then, the airtight door 61 is pushed by the push cylinder 62 to close the vacuum drying chamber 4, making the vacuum drying chamber 4 a sealed space.

[0027] Furthermore, such as Figure 1 as well as Figure 3 As shown, an air cutting assembly 7 is installed on the surface of the frame 1 and on one side of the air cutting groove 3. The air cutting assembly 7 is used for air cutting of products inside the air cutting groove 3. The air cutting assembly 7 includes a carrier plate 71, an air cutting cylinder 72, and an air cutting pipe and nozzle 73. The carrier plate 71 is fixed to the surface of the frame 1, and a slider is slidably connected to the surface of the carrier plate 71.

When the air-cutting pipe and nozzle 73 blow air, the water remaining in the precision mold hole will be blown away.

[0029] Working principle: When in use, the basket containing the dried precision mold is placed into the air cutting groove 3. After placement, the shielding door 51 is pushed by the push-pull cylinder 52 to shield the air cutting groove 3. Then, the air cutting cylinder 72 on the surface of the carrier plate 71 drives the air cutting pipe and nozzle 73 on the surface of the slider to move, so that the air outlet end of the air cutting pipe and nozzle 73 reciprocates inside the air cutting groove 3. When the air cutting pipe and nozzle 73 blow air, the water remaining in the precision mold hole will be blown away, thereby realizing the air cutting function.

[0030] After air cutting, the basket containing the precision mold is placed inside the vacuum drying tank 4. Then, the sealing door 61 is pushed by the push cylinder 62 to close the vacuum drying tank 4, making the vacuum drying tank 4 a sealed space. Subsequently, the vacuum flange terminal 42 is connected to the vacuum pump, and the vacuum pump is used to evacuate the inside of the vacuum drying tank 4. During the vacuum process, the vacuum pressure inside the vacuum drying tank 4 is detected by the digital pressure gauge 60. At the same time, the infrared heating tube 41 inside the vacuum drying tank 4 will heat and detect the temperature, thereby completing the drying of the precision mold.
