Description

Technical Field

[0001] This utility model relates to the field of tire manufacturing technology, and in particular to a rapid prototyping mold for tire manufacturing. Background Technology

[0002] Tires are circular, elastic rubber products that are mounted on various vehicles or machinery and roll on the ground. They are usually mounted on metal rims, support the vehicle body, buffer external impacts, make contact with the road surface, and ensure the vehicle's driving performance.

[0003] In the tire manufacturing process, the molding die is a key piece of equipment that determines the vulcanization and molding of the tire blank. Existing tire molding dies often suffer from difficulties in cleaning the interior of the die cavity. Residual sulfides or impurities can easily affect the quality of subsequent tire molding. Traditional cleaning methods rely heavily on manual wiping, which is not only labor-intensive and time-consuming with low cleaning efficiency, but also difficult to thoroughly clean some hidden corners inside the cavity, thus negatively impacting tire production quality and lacking practicality. Therefore, a new rapid prototyping die for tire production needs to be redesigned to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rapid prototyping mold for tire production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rapid prototyping mold for tire production includes a base. A lower mold is fixedly mounted on the upper surface of the base. A cooling pipe is wound around the outer wall of the lower mold. A rotating shaft is rotatably mounted on the upper surface of the base via a support frame. A conical rotor motor connected to the rotating shaft is fixedly mounted on the outer wall of the support frame. An mounting sleeve is fixedly mounted on the outer wall of the rotating shaft. A fixing plate is fixedly connected to the outer wall of the mounting sleeve via a connecting mechanism. A bearing is fixedly mounted on the upper surface of the fixing plate through a mounting opening. A rotating tube is fixedly mounted on the inner ring of the bearing. An air inlet hose is fixedly mounted on the outer wall of the rotating tube via a connecting mechanism. A connecting pipe is fixedly mounted on the outer wall of the rotating tube. Two air nozzles communicating with the interior are fixedly mounted on the outer wall of the connecting pipe. A servo motor is fixedly mounted on the upper surface of the fixing plate. Gears are fixedly mounted on both the output shaft of the servo motor and the outer wall of the rotating tube, and the two gears mesh with each other.

[0007] Preferably, the connecting mechanism includes a connecting plate fixedly installed on the outer wall of the mounting sleeve, and the end of the connecting plate is fixedly connected to the upper surface of the fixing plate.

[0008] Preferably, the connecting mechanism includes a connecting sleeve rotatably mounted on the outer wall of the rotating pipe, and the outer wall of the air intake hose is fixedly connected to the inner wall of the connecting sleeve.

[0009] Preferably, a water tank is fixedly installed on the inner bottom wall of the base, and a filling port communicating with the interior is opened on the upper surface of the water tank, with one end of the cooling pipe extending into the filling port.

[0010] Preferably, a circulation pump is fixedly installed on the upper surface of the water tank, the other end of the cooling pipe is fixedly connected to the outer wall of the circulation pump outlet pipe, the circulation pump inlet pipe extends into the water tank, a cooler is fixedly installed on the outer wall of the water tank, the cold end of the cooler extends into the water tank, and a drain pipe communicating with the interior is fixedly installed on the outer wall of the water tank.

[0011] Preferably, a controller is fixedly installed on the outer wall of the water tank, and the controller is electrically connected to the circulating pump, the cooler, the conical rotor motor and the servo motor.

[0012] The beneficial effects of this utility model are:

[0013] 1. By setting up components such as rotating tubes, air nozzles, and gears, the servo motor drives the gears to rotate the rotating tubes and air nozzles. Combined with the high-pressure gas from the air intake hose, it can clean the inside of the lower mold in all directions without the need for manual wiping, saving manpower and time, improving cleaning efficiency, removing hidden residues, avoiding affecting the tire molding quality, and improving production reliability.

[0014] 2. By setting up components such as a rotating shaft, a conical rotor motor, and a connecting plate, the conical rotor motor drives the rotating shaft, which, through the mounting sleeve and connecting plate, causes the fixing plate and air nozzle to rotate as a whole. This facilitates the adjustment of the air nozzle position, allows it to be moved away from the lower mold during molding to avoid interference, and enables it to be quickly moved to a suitable position during cleaning, thereby enhancing the flexibility and convenience of use and improving the practicality of the equipment.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A rapid prototyping mold for tire production includes a base 1, a lower mold 2 fixedly mounted on the upper surface of the base 1, a cooling pipe 3 wound around the outer wall of the lower mold 2, a rotating shaft 9 rotatably mounted on the upper surface of the base 1 via a support frame 8, a conical rotor motor 10 connected to the rotating shaft 9 fixedly mounted on the outer wall of the support frame 8, an mounting sleeve 11 fixedly mounted on the outer wall of the rotating shaft 9, a fixing plate 13 fixedly connected to the outer wall of the mounting sleeve 11 via a connecting mechanism, a bearing 14 fixedly mounted on the upper surface of the fixing plate 13 via an installation opening, a rotating tube 15 fixedly mounted on the inner ring of the bearing 14, an air inlet hose 17 fixedly mounted on the outer wall of the rotating tube 15 via a connecting mechanism, a connecting pipe 18 fixedly mounted on the outer wall of the rotating tube 15, two air nozzles 19 communicating with the interior fixedly mounted on the outer wall of the connecting pipe 18, a servo motor 20 fixedly mounted on the upper surface of the fixing plate 13, and gears 21 fixedly mounted on both the output shaft of the servo motor 20 and the outer wall of the rotating tube 15, with the two gears 21 meshing with each other.

[0023] The connecting mechanism includes a connecting plate 12 fixedly installed on the outer wall of the mounting sleeve 11, and the end of the connecting plate 12 is fixedly connected to the upper end face of the fixing plate 13.

[0024] Furthermore, the connecting plate 12 securely connects the mounting sleeve 11 to the fixing plate 13, ensuring that the fixing plate 13 and the components above it can move synchronously and stably when the rotating shaft 9 rotates, thus avoiding the impact on the working accuracy of components such as the air nozzle 19 due to loose connection.

[0025] The connecting mechanism includes a connecting sleeve 16 rotatably mounted on the outer wall of the rotating pipe 15, and the outer wall of the air intake hose 17 is fixedly connected to the inner wall of the connecting sleeve 16.

[0026] Furthermore, the connection sleeve 16 ensures that the air intake hose 17 remains relatively fixed during the rotation of the rotating pipe 15, preventing it from twisting along with the rotating pipe 15 and ensuring a stable supply of air to the rotating pipe 15.

[0027] A water tank 4 is fixedly installed on the inner bottom wall of the base 1. A filling port communicating with the interior is opened on the upper surface of the water tank 4, and one end of the cooling pipe 3 extends into the filling port.

[0028] Furthermore, the filling port not only facilitates the replenishment of coolant into the water tank 4, but also allows the coolant output from the cooling pipe 3 to flow smoothly back to the water tank 4, forming a preliminary circulation path and laying the foundation for the operation of the subsequent cooling circulation system.

[0029] A circulation pump 5 is fixedly installed on the upper surface of the water tank 4. The other end of the cooling pipe 3 is fixedly connected to the outer wall of the outlet pipe of the circulation pump 5. The inlet pipe of the circulation pump 5 extends into the interior of the water tank 4. A cooler 6 is fixedly installed on the outer wall of the water tank 4. The cold end of the cooler 6 extends into the interior of the water tank 4. A drain pipe 7 connected to the interior is fixedly installed on the outer wall of the water tank 4.

[0030] Furthermore, the circulation pump 5 provides power for the circulation of coolant between the cooling pipe 3 and the water tank 4, while the cooler 6 continuously cools the coolant in the water tank 4 to ensure the cooling effect, and the drain pipe 7 can periodically discharge impurities and sewage from the water tank 4 to maintain the cleanliness of the coolant.

[0031] A controller 22 is fixedly installed on the outer wall of the water tank 4. The controller 22 is electrically connected to the circulating pump 5, the cooler 6, the conical rotor motor 10, and the servo motor 20.

[0032] Furthermore, the controller 22 can precisely control the operating parameters of each component, such as the flow rate of the circulating pump 5, the cooling temperature of the cooler 6, and the rotation speed of the conical rotor motor 10 and the servo motor 20, thereby achieving automated and precise mold operation and improving tire molding efficiency and quality.

[0033] When this utility model is in use, after the tire is formed in the lower mold 2, the controller 22 starts the circulation pump 5 and the cooler 6. The cooler 6 cools the coolant in the water tank 4. The circulation pump 5 pumps the coolant into the cooling pipe 3. The coolant flows in the cooling pipe 3, absorbing the heat of the lower mold 2 and the tire, and then flows back to the water tank 4 to achieve rapid cooling. After cooling is completed, if it is necessary to clean the inside of the lower mold 2, the controller 22 can start the conical rotor motor 10. The conical rotor motor 10 drives the rotating shaft 9 to rotate. The rotating shaft 9 drives the fixing plate 13 to rotate through the mounting sleeve 11 and the connecting mechanism, so that the air nozzle 19 moves to a suitable position above the lower mold 2.

[0034] Next, the servo motor 20 is started. The gear 21 on the output shaft of the servo motor 20 drives the gear 21 on the outer wall of the rotating tube 15 to rotate, thereby causing the rotating tube 15 to rotate in the inner ring of the bearing 14. The connecting tube 18 and the air nozzle 19 rotate accordingly. At the same time, high-pressure gas is introduced through the air inlet hose 17. The gas is ejected from the air nozzle 19 through the rotating tube 15 and the connecting tube 18. The rotating air nozzle 19 can perform all-round cleaning of the interior of the lower mold 2, effectively removing residual sulfides or impurities. After cleaning is completed, the servo motor 20 is turned off by the controller 22 and the air supply of the air inlet hose 17 is cut off to avoid the equipment running idle and gas waste. Subsequently, the conical rotor motor 10 is started, and the rotating shaft 9 drives the mounting sleeve 11, the fixing plate 13 and other structures to rotate back to the initial position, so that the air nozzle 19 and other components are away from the top of the lower mold 2 and do not occupy the subsequent operation space.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
