Description

Technical Field

[0001] This utility model relates to the field of die-casting equipment technology, specifically to a die-casting equipment for preparing self-lubricating bearings. Background Technology

[0002] Die casting is a production method in which molten metal or alloy is injected into a mold under high pressure for casting. In the manufacture of self-lubricating bearings, the use of die casting equipment mainly involves combining lubricating materials with metal materials to form a composite structure for the self-lubricating bearing. Once the metal and lubricating material fill the mold, the cooling process begins. During this process, the metal alloy solidifies and forms the basic structure of the bearing. After cooling, the bearing is demolded and subjected to necessary post-processing, such as removing excess metal, surface polishing, and heat treatment, to ensure the final performance of the bearing.

[0003] However, in use, the process begins by heating the metal material (such as aluminum alloy, copper alloy, etc.) to a liquid state. The metal is typically melted at high temperatures. The molten metal is then rapidly injected into a precision mold in a die-casting machine using high-pressure injection. The die-casting machine ensures that the metal fills every corner of the mold through high-pressure injection. The metal injected into the mold cools rapidly and solidifies. In piston-type injection, the piston is hydraulically pushed into the mold by a piston. The molten metal is then poured into the injection tube by the operator. When pouring the molten metal, the temperature of the metal is extremely high (usually between 700°C and 900°C). Improper operation may cause the molten metal to splash out, resulting in burns or other serious injuries to the operator. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figure 1-5As shown in this embodiment, a die-casting device for preparing self-lubricating bearings includes an automatic pouring assembly 200. The automatic pouring assembly 200 includes a pouring cylinder 215. Connecting plates 208 are bolted to both sides of the pouring cylinder 215. A rotating rod 212 is rotatably connected inside the connecting plate 208. One end of the rotating rod 212 is installed on both sides of the pouring cylinder 215, and a micro motor 211 is fixedly installed at one end of the rotating rod 212. One end of the connecting plate 208 is connected by a rotating bolt 213. Connecting rod 209 is fixedly connected. One end of connecting rod 209 is rotatably connected to the outside of fixed rod 210. Discharge cylinder 215 corresponds to the upper end of feed inlet 106 of injection tube 105. A sliding block 207 is fixedly installed on the upper end of connecting plate 208. The sliding block 207 is slidably connected to the inside of moving guide plate 202. A guide groove 205 is provided inside the moving guide plate 202. A lead screw 206 is rotatably connected inside the sliding block 207. One end of the automatic pouring assembly 200 is equipped with a servo motor 201, which is bolted to one end of the moving guide plate 202. In actual use, the automatic pouring assembly 200 is started by the control system, which includes a micro motor 211, a servo motor 201, and other driving devices. The micro motor 211 drives the rotating rod 212, which rotates the pouring cylinder 215, allowing the molten metal to enter the injection tube 105 through the pouring cylinder 215. When the pouring cylinder 215 rotates, it drives the connecting rod 209 to rotate. The servo motor 201 drives the lead screw 206, which moves the sliding block 207 along the moving guide plate 202, ensuring that the pouring cylinder 215 can be accurately aligned with the feed slot 106 of the injection tube 105 so that the molten metal can be poured into the injection tube 105 smoothly. After the molten metal is poured into the mold and filled, the pouring cylinder 215 stops rotating and the sliding block 207 is moved out under the control of the servo motor 201 for the next operation.

[0022] By adopting an automatic material pouring device, operators do not need to directly contact the high-temperature metal. The automatic material pouring process reduces the possibility of human error, especially in high-temperature environments, and avoids accidents caused by improper operation. Driven by the servo motor 201 and the micro motor 211, the automatic material pouring component 200 starts to work, the pouring cylinder 215 rotates and begins to pour in molten metal. Through this process, the molten metal can be smoothly poured into the injection tube 105.

[0023] like Figure 1-2As shown, a fixed plate 302 is fixedly installed at the middle of the upper end of the movable guide plate 202. A telescopic guide post 301 is fixedly installed at one end of the fixed plate 302. A second hydraulic cylinder 300 is installed at one end of the telescopic guide post 301. A fixed block 204 is fixedly installed at the upper end of the movable guide plate 202. A sliding hole 203 is opened inside the fixed block 204. A support guide post 102 is connected through the sliding hole 203. By driving the second hydraulic cylinder 300, the telescopic guide post 301 is moved, which further pushes the movable guide plate 202 to move on the support guide post 102, moving the automatic material pouring component 200 to the position of the injection tube 105.

[0024] like Figure 1 As shown, the two ends of the support guide column 102 are fixedly installed at one end of the support frame plate 101. The lower end of the support frame plate 101 is connected to the upper end of the base 100 by bolts. An injection tube 105 is fixedly installed at one end of the support frame plate 101. A feed slot 106 is opened on the outside of the injection tube 105. A hydraulic push column 104 is pushed inside the injection tube 105. A first hydraulic cylinder 103 is fixedly installed at one end of the hydraulic push column 104. When the first hydraulic cylinder 103 starts to work, hydraulic fluid enters the hydraulic cylinder through the pipe, thereby pushing the hydraulic push column 104 forward, further pushing the molten metal inside the injection tube 105 into the die-casting mold. The molten metal injected into the mold begins to cool and solidify. This process is controlled by the cooling system to ensure the dimensional accuracy and surface quality of the formed bearing parts. When the metal bearing has completely cooled and solidified, the mold is opened and the formed bearing parts are taken out.

[0025] This utility model provides a die-casting equipment for preparing self-lubricating bearings. The specific working principle is as follows: The second hydraulic cylinder 300 drives the telescopic guide column 301 to move, further pushing the moving guide plate 202 on the supporting guide column 102, moving the automatic pouring assembly 200 to the injection tube 105. The automatic pouring assembly 200 is activated by the control system, which includes a micro motor 211, a servo motor 201, and other driving devices. The micro motor 211 drives the rotating rod 212, causing the pouring cylinder 215 to rotate, thus allowing molten metal to enter the injection tube 105 through the pouring cylinder 215. When the pouring cylinder 215 rotates, it in turn drives the connecting rod 209 to rotate. The servo motor 201 drives the lead screw 206, causing the sliding block 207 to move along the moving guide plate 202. 02. Move the pouring cylinder 215 to ensure that it is precisely aligned with the feed slot 106 of the injection tube 105 so that the molten metal can be smoothly poured into the injection tube 105. After the molten metal is poured into the mold and filled, the pouring cylinder 215 stops rotating and the sliding block 207 is moved out under the control of the servo motor 201 so that the next operation can be carried out. When the first hydraulic cylinder 103 starts to work, the hydraulic fluid enters the hydraulic cylinder through the pipe, thereby pushing the hydraulic push column 104 forward, further pushing the molten metal inside the injection tube 105 into the die-casting mold. The molten metal injected into the mold begins to cool and solidify. This process is controlled by the cooling system to ensure the dimensional accuracy and surface quality of the formed bearing parts. When the metal bearing has completely cooled and solidified, the mold is opened and the formed bearing parts are taken out.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
