Description

Technical Field

[0001] This utility model belongs to the field of dental prosthesis casting technology, and relates to a dental prosthesis casting machine with a liquid cooling channel. Background Technology

[0002] Dentures, in medical terms, are a general term for restorations made after partial or complete loss of the upper and lower jaw teeth. Current dentures are divided into two types: removable and fixed. Fixed dentures cannot be removed by the patient, while removable dentures can be easily removed and inserted by the patient. Current denture fabrication is generally achieved using a denture casting machine. The casting machine injects raw materials into a mold, which is then cooled to shape the denture.

[0003] The following technical problems were found in the existing technology: When injecting raw materials into the mold, the existing denture casting machine is not easy to control the amount of raw materials injected. Injecting too much wastes raw materials, while injecting too little affects the denture forming. Utility Model Content

[0004] The technical problem to be solved by this utility model is that existing denture casting machines are not easy to control the amount of raw materials injected into the mold. Injecting too much wastes raw materials, while injecting too little affects the denture molding.

[0005] This utility model discloses a dental prosthesis casting machine with a liquid cooling channel, comprising a machine body, with support legs fixedly connected to the four corners of the bottom surface of the machine body, an air inlet on one side of the machine body, and a door hinged to the other side of the machine body. An air outlet is provided through the inside of the door, corresponding to the air inlet. A motor is fixedly connected to the center of the outer top surface of the machine body, a heating tank is fixedly connected to the inner top surface of the machine body, corresponding to the motor, and a storage tank is fixedly connected to the outer top surface of the machine body, corresponding to the heating tank. The storage tank is connected to the heating tank, a quantitative feeding mechanism is provided at the bottom of the heating tank, a support frame is fixedly connected to the inner bottom surface of the machine body, an electric chuck is fixedly installed on the top of the support frame, and a cooling mechanism is provided on the side of the support frame near the air inlet.

[0006] The output end of the motor passes through the top surface of the machine body and extends into the interior of the heating tank, and the output end of the motor is fixedly connected to a stirring roller.

[0007] The quantitative feeding mechanism includes a T-shaped tube, a first one-way valve, a second one-way valve, and a discharge pipe. The T-shaped tube is fixedly connected to the bottom opening of the heating tank. The first one-way valve and the second one-way valve are symmetrically installed inside the vertical pipe of the T-shaped tube. The discharge pipe is fixedly connected to the bottom of the vertical pipe of the T-shaped tube.

[0008] The quantitative feeding mechanism also includes a servo electric cylinder and a circular piston. An installation plate is fixedly connected to the inner wall of the machine body near the door and corresponding to the T-shaped tube. A servo electric cylinder is fixedly connected to the top surface of the installation plate and corresponding to the T-shaped tube. The output end of the servo electric cylinder extends into the horizontal pipe of the T-shaped tube, and a circular piston is fixedly connected to the output end of the servo electric cylinder.

[0009] The cooling mechanism includes a movable plate, a fixed frame, and an electric push rod. The inner walls of the support frame on opposite sides are provided with sliding grooves, and the movable plate is slidably connected inside the sliding grooves. The fixed frame is fixedly connected at the center of the bottom surface of the machine body, and the electric push rod is installed inside the fixed frame. The output end of the electric push rod extends into the machine body and is fixedly connected to the movable plate.

[0010] The cooling mechanism also includes an intake fan, a connecting plate, a cooling pipe, and a cooling pump. An intake fan is installed inside the intake hole. A connecting plate is fixedly connected to one side of the support frame near the intake hole. A cooling pipe is fixedly connected to the other side of the connecting plate. A cooling pump is installed on the top surface of the support frame near the connecting plate. The cooling pump is connected to the cooling pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. A servo electric cylinder controls the movement of a circular piston within a T-tube. When the output end of the servo electric cylinder retracts and moves the circular piston, the first one-way valve opens and the second one-way valve closes. The raw material, heated and melted by the heating tank, enters the T-tube through the first one-way valve. When the output end of the servo electric cylinder extends and moves the circular piston, the first one-way valve closes and the second one-way valve opens, allowing the raw material to be injected into the mold through the discharge pipe. By precisely controlling the stroke of the circular piston within the T-tube using the servo electric cylinder, the amount of raw material injected can be flexibly adjusted according to the mold size, avoiding material waste.

[0012] 2. The mold is clamped by an electric chuck, and the raw material is injected into the mold through the discharge pipe. After the raw material is injected, the electric chuck is activated to release the clamp, and then the electric push rod is activated to move the movable plate and the mold downward. At the same time, the cooling pump and the air intake fan are activated. The cooling pump makes the coolant in the cooling pipe flow, and the air intake fan drives the airflow through the cooling pipe and blows it onto the mold to cool the mold and the denture inside, effectively improving the cooling efficiency. At the same time, it avoids the mold directly contacting the coolant, which would cause the denture to cool down too quickly and cause defects. Attached Figure Description

[0020] Example like Figures 1-6 As shown, a denture casting machine with a liquid cooling channel includes a body 1. Support legs 101 are fixedly connected to the four corners of the bottom surface of the body 1. An air inlet 102 is provided on one side of the body 1, and a door 8 is hinged to the other side. An air outlet 801 is provided through the door 8, corresponding to the air inlet 102. The symmetrically provided air inlet 102 and air outlet 801 accelerate air circulation within the body 1. A motor 2 is fixedly connected to the center of the outer top surface of the body 1, and a heating tank 3 is fixedly connected to the inner top surface of the body 1, corresponding to the motor 2. The heating tank 3 heats and melts the raw materials. The output end of motor 2 passes through the top surface of machine body 1 and extends into the interior of heating tank 3. A stirring roller 201 is fixedly connected to the output end of motor 2. Motor 2 drives the stirring roller 201 to rotate, so that the raw materials inside heating tank 3 are heated and melted more evenly. A storage box 4 is fixedly connected to the outer top surface of machine body 1 and corresponding to the heating tank 3. The storage box 4 is connected to the heating tank 3. A quantitative feeding mechanism is provided at the bottom of heating tank 3. A support frame 9 is fixedly connected to the inner bottom surface of machine body 1. An electric chuck 10 is fixedly installed on the top of support frame 9. A cooling mechanism is provided on the side of support frame 9 near air inlet 102.

[0021] In use, the raw materials are first added to the heating tank 3 through the storage box 4, and then the heating tank 3 and the motor 2 are started. The motor 2 drives the stirring roller 201 to rotate, stirring the raw materials in the heating tank 3 so that the raw materials are heated and melted evenly, which is convenient for subsequent casting of dentures.

[0022] The quantitative feeding mechanism includes a T-shaped tube 5, a first one-way valve 501, a second one-way valve 502, and a discharge pipe 503. A T-shaped tube 5 is fixedly connected to the bottom opening of the heating tank 3. The T-shaped tube 5 is composed of intersecting vertical and horizontal pipes. The first one-way valve 501 and the second one-way valve 502 are symmetrically installed inside the vertical pipe of the T-shaped tube 5. The discharge pipe 503 is fixedly connected to the bottom end of the vertical pipe of the T-shaped tube 5. The inner wall of the machine body 1 near the door 8 is fixedly connected to the T-shaped tube 5 at a location corresponding to it. There is a mounting plate 6, which provides support for the T-shaped tube 5 and the servo cylinder 7. The servo cylinder 7 is fixedly connected to the top surface of the mounting plate 6 and to the corresponding position of the T-shaped tube 5. The servo cylinder 7 can precisely control the extension stroke. The output end of the servo cylinder 7 extends into the horizontal pipe of the T-shaped tube 5, and a circular piston 701 is fixedly connected to the output end of the servo cylinder 7. By precisely controlling the stroke of the circular piston 701 in the T-shaped tube 5 through the servo cylinder 7, quantitative feeding can be achieved, avoiding material waste.

[0023] In use, the servo cylinder 7 is first started. When the output end of the servo cylinder 7 retracts and drives the circular piston 701 to move, the first one-way valve 501 is opened and the second one-way valve 502 is closed. The raw material heated and melted by the heating tank 3 enters the T-tube 5 through the first one-way valve 501. When the output end of the servo cylinder 7 extends and drives the circular piston 701 to move, the first one-way valve 501 is closed and the second one-way valve 502 is opened. The raw material is injected into the mold through the discharge pipe 503. By precisely controlling the stroke of the circular piston 701 in the T-tube 5 through the servo cylinder 7, the amount of raw material injected can be flexibly adjusted according to the size of the mold, avoiding waste of raw material.

[0024] The cooling mechanism includes a movable plate 11, a fixed frame 12, and an electric push rod 1201. The inner walls of opposite sides of the support frame 9 are provided with sliding grooves 901, through which the movable plate 11 is slidably connected. The sliding grooves 901 guide the movement of the movable plate 11. A fixed frame 12 is fixedly connected to the center of the bottom surface of the body 1. An electric push rod 1201 is installed inside the fixed frame 12. The output end of the electric push rod 1201 extends into the body 1 and is fixedly connected to the movable plate 11. The electric push rod 1201 can drive the movable plate. 11. The machine moves up and down. An air intake fan 103 is installed in the air intake hole 102. The air intake fan 103 can accelerate the air circulation in the machine body 1. A connecting plate 13 is fixedly connected to the side of the support frame 9 near the air intake hole 102. A cooling pipe 1301 is fixedly connected to the other side of the connecting plate 13. The air is cooled by passing through the cooling pipe 1301 and blown towards the mold, which can accelerate the cooling of the mold. A cooling pump 1302 is installed on the top surface of the support frame 9 near the connecting plate 13. The cooling pump 1302 is connected to the cooling pipe 1301.

[0025] In use, the mold is placed on the top surface of the movable plate 11 and clamped by the electric chuck 10. Then, the raw material is injected into the mold through the discharge pipe 503. After the raw material is injected, the electric chuck 10 is activated to release the clamp, and the electric push rod 1201 is activated to move the movable plate 11 and the mold downward. At the same time, the cooling pump 1302 and the air intake fan 103 are activated. The cooling pump 1302 causes the coolant in the cooling pipe 1301 to flow and cool the surrounding air. The air intake fan 103 drives the airflow through the cooling pipe 1301 and blows it onto the mold to cool the mold and the denture inside, effectively improving the cooling efficiency. At the same time, it avoids the mold from directly contacting the coolant, which would cause the denture to cool down too quickly and cause defects.

[0026] During operation, the raw materials are first added to the heating tank 3 through the storage bin 4. Then, the heating tank 3 and motor 2 are started. The motor 2 drives the stirring roller 201 to rotate, stirring the raw materials in the heating tank 3 to ensure uniform heating and melting. The mold is placed on the top surface of the movable plate 11 and clamped by the electric chuck 10. The servo cylinder 7 is started. When the output end of the servo cylinder 7 retracts and moves the circular piston 701, the first one-way valve 501 is opened and the second one-way valve 502 is closed. The raw materials heated and melted by the heating tank 3 enter the T-tube 5 through the first one-way valve 501. When the output end of the servo cylinder 7 extends and moves the circular piston 701... The first one-way valve 501 is closed, and the second one-way valve 502 is opened. The raw material is injected into the mold through the discharge pipe 503. After the raw material is injected, the electric chuck 10 is activated to release the clamp, and the electric push rod 1201 is activated to move the movable plate 11 and the mold downward. At the same time, the cooling pump 1302 and the air intake fan 103 are activated. The cooling pump 1302 causes the coolant in the cooling pipe 1301 to flow and cool the surrounding air. The air intake fan 103 drives the airflow through the cooling pipe 1301 and blows it onto the mold to cool the mold and the denture inside, effectively improving the cooling efficiency. At the same time, it avoids the mold from directly contacting the coolant, which would cause the denture to cool down too quickly and cause defects.
