Description

Technical Field

[0001] This utility model relates to the field of metallurgical manufacturing, specifically a symmetrical and reversible iron mold casting machine. Background Technology

[0002] Modern cast iron machines have replaced the early, inefficient sand casting. They employ a circulating chain system, which uses sprockets to drive a series of metal chain links equipped with molten iron troughs. After receiving molten iron in the pouring section, the machines undergo water cooling, demolding, and other processes to achieve automated production, significantly improving the efficiency and safety of cast iron production.

[0003] When a casting machine is in use, the molten iron in the molten iron tank will continuously absorb heat from the metal tank wall, causing the temperature to drop to the solidification point. Oxides, impurities and other slag on the surface of the molten iron will adhere to the tank, contaminating the molten iron that flows through later. This will eventually lead to quality defects such as porosity and slag inclusions in the castings. If these residues are not cleaned in time, they will seriously disrupt the continuity of production and create safety hazards. Summary of the Invention

[0004] To address the shortcomings of existing technologies, where residues inside the molten iron trough can cause quality defects in castings such as porosity and slag inclusions, severely disrupting production continuity, this invention proposes a symmetrical, reversible iron mold casting machine.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0018] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses a symmetrical, reversible iron mold casting machine. (See also...) Figure 1 and Figure 3A symmetrical, reversible iron mold casting machine includes a frame 1. A first rotating shaft 101 is rotatably connected inside the frame 1. One end of the first rotating shaft 101 passes through the frame 1 and is rotatably connected to the inner cavity of the frame 1. A motor 111 is fixedly installed on one side of the frame 1. The output end of the motor 111 is fixedly connected to one end of the first rotating shaft 101. A first sprocket 102 is fixedly sleeved on the surface of the first rotating shaft 101. A second rotating shaft 103 is rotatably connected inside the frame 1. A second sprocket 104 is fixedly sleeved on the surface of the second rotating shaft 103. A chain 105 is mounted on the surface of the first sprocket 102 and the surface of the second sprocket 104. Several supports 106 are fixedly connected to the surface of the chain 105. A molten iron tank 107 is rotatably connected inside the supports 106. A scraping mechanism 2 is provided inside the frame 1. The scraping mechanism 2 works in conjunction with the molten iron tank 107. A positioning component 4 is provided inside the supports 106. The positioning component 4 works in conjunction with a rotating rod 108. The scraping mechanism 2 includes a reciprocating lead screw 201 rotatably connected inside the frame 1. A moving block 202 is threaded onto the surface of the reciprocating lead screw 201. A connecting rod 203 is fixedly connected to the surface of the moving block 202. A support rod 204 is rotatably connected to one end of the connecting rod 203. A scraper 205 is rotatably connected to one end of the support rod 204. The scraper 205 works in conjunction with the molten iron trough 107. One end of a second rotating shaft 103 passes through the frame 1 and is rotatably connected to the inner cavity of the frame 1. A transmission assembly 3 is provided at one end of the second rotating shaft 103. The transmission assembly 3 works in conjunction with the reciprocating lead screw 201. When using the casting machine, the motor 111 is started. 11 The first sprocket 102 is driven to rotate by the first rotating shaft 101. The first sprocket 102 drives the second sprocket 104 to rotate via the chain 105. The second sprocket 104 drives the second rotating shaft 103 to rotate. At this time, the molten iron tank 107 rotates with the chain 105. The second rotating shaft 103 drives the reciprocating screw 201 to rotate via the transmission assembly 3. The rotation of the reciprocating screw 201 causes the moving block 202 to move the connecting rod 203. The connecting rod 203 drives the scraper 205 to move via the support rod 204. The scraper 205 scrapes away the residue inside the molten iron tank 107, which can effectively ensure the cleanliness of the inside of the molten iron tank 107 and guarantee the product quality of the casting.

[0019] Reference Figure 1 and Figure 3 The frame 1 has two fixed rods 206 fixedly connected inside. The inner cavity of the moving block 202 is slidably sleeved on the surface of the fixed rods 206. When the reciprocating screw 201 rotates, the moving block 202 is positioned by the fixed rods 206, so that the moving block 202 can slide on the surface of the reciprocating screw 201, and the moving block 202 is prevented from rotating with the reciprocating screw 201.

[0020] Reference Figure 1 and Figure 3Two torsion springs 207 are provided at one end of the connecting rod 203. One end of the torsion spring 207 is fixedly connected to the inside of the connecting rod 203, and the other end of the torsion spring 207 is fixedly connected to the surface of the support rod 204. When the scraper 205 cleans the inside of the molten iron tank 107, the chain 105 drives the molten iron tank 107 to rotate. The inner cavity of the molten iron tank 107 contacts the support rod 204, and the support rod 204 rotates and presses down at one end of the connecting rod 203, thereby preventing the support rod 204 from getting stuck inside the molten iron tank 107. After the support rod 204 is pressed down and separated from the inner cavity of the molten iron tank 107, the torsion spring 207 drives the support rod 204 to reset, so that the next molten iron tank 107 can be scraped and cleaned.

[0021] Reference Figure 2 The transmission assembly 3 includes a second gear 301 fixedly sleeved on one end of the second rotating shaft 103, a reciprocating screw 201 with one end passing through the frame 1 and rotatably connected to the inner cavity of the frame 1, a third gear 302 fixedly sleeved on one end of the reciprocating screw 201, and a synchronous toothed belt 303 sleeved on the surface of the second gear 301 and the surface of the third gear 302; when the second sprocket 104 drives the second rotating shaft 103 to rotate, the second rotating shaft 103 drives the second gear 301 to rotate, the second gear 301 causes the third gear 302 to rotate through the synchronous toothed belt 303, and the third gear 302 drives the reciprocating screw 201 to rotate, thereby causing the scraper 205 to scrape back and forth inside the molten iron tank 107 through the rotation of the reciprocating screw 201.

[0022] Reference Figure 1 and Figure 4 The bracket 106 is rotatably connected to a rotating rod 108. The inner cavity of the molten iron trough 107 is fixedly sleeved on the surface of the rotating rod 108. One end of the rotating rod 108 passes through the bracket 106 and is rotatably connected to the inner cavity of the bracket 106. A first gear 109 is fixedly sleeved on one end of the rotating rod 108. A rack 110 is fixedly connected inside the frame 1. The first gear 109 works in conjunction with the rack 110. When the chain 105 drives the bracket 106 to rotate, the bracket 106 drives the first gear 109 to rotate with the chain 105. When the first gear 109 contacts the rack 110, the first gear 109 drives the rotating rod 108 to rotate. The rotating rod 108 drives the molten iron trough 107 to rotate, so that the molten iron trough 107 can be flipped up and down, thereby achieving the purpose of using the upper and lower surfaces of the molten iron trough 107 alternately.

[0023] Reference Figure 4 and Figure 5The positioning component 4 includes a slide groove 401 formed inside the bracket 106, and a positioning groove 402 formed in the inner cavity of the slide groove 401. A sleeve rod 403 is fixedly connected to the surface of the rotating rod 108. An inner rod 404 is slidably connected to the inner cavity of the sleeve rod 403. One end of the inner rod 404 passes through the sleeve rod 403 and is slidably connected to the inner cavity of the sleeve rod 403. The inner rod 404 cooperates with the positioning groove 402. A spring 405 is provided inside the sleeve rod 403. One end of the spring 405 is fixedly connected to the inside of the sleeve rod 403. The other end of the spring 405 is fixedly connected to the other end of the inner rod 404. When the rotating rod 108 rotates, the rotating rod 108 drives the inner rod 404 to rotate through the sleeve rod 403. The inner rod 404 slides in the slide groove 401. When the inner rod 404 slides to the positioning groove 402, the spring 405 pushes the inner rod 404, so that the inner rod 404 is inserted into the positioning groove 402. In order to position the molten iron tank 107 through the cooperation of the inner rod 404 and the positioning groove 402, the molten iron tank 107 is prevented from rotating incorrectly or having an incorrect angle.

[0024] Reference Figure 4 and Figure 5 A stop 406 is fixedly connected inside the sleeve rod 403, and a protrusion 407 is fixedly connected to one end of the inner rod 404. The stop 406 and the protrusion 407 work together. The stability of the stop 406 and the protrusion 407 ensures the position of the inner rod 404 in the inner cavity of the sleeve rod 403 and prevents the inner rod 404 from falling out of the inner cavity of the sleeve rod 403.

[0025] Working principle: When using the casting machine, the motor 111 is started. The motor 111 drives the first sprocket 102 to rotate via the first rotating shaft 101. The first sprocket 102 drives the second sprocket 104 to rotate via the chain 105. At this time, the bracket 106 and the molten iron tank 107 rotate with the chain 105. The second sprocket 104 drives the second gear 301 to rotate via the second rotating shaft 103. The second gear 301 drives the third gear 302 to rotate via the synchronous toothed belt 303. The third gear 302 drives the reciprocating screw 201 to rotate. Through the stabilization of the fixed rod 206, the rotation of the reciprocating screw 201 drives the moving block 202 to move. The moving block 202 drives the support rod 204 to move via the connecting rod 203. The support rod 204 drives the scraper 205 to move in the molten iron tank 107. The internal scraping mechanism of 07 removes residue from the inside of the molten iron tank 107. As the molten iron tank 107 continues to rotate with the chain 105, its inner cavity contacts the support rod 204, causing the support rod 204 to rotate and press down inside the connecting rod 203. This allows the support rod 204 to separate from the inside of the molten iron tank 107, preventing it from getting stuck inside. When the molten iron tank 107 and the bracket 106 rotate with the chain 105, and the bracket 106 drives the first gear 109 to contact the rack 110, the first gear 109 drives the rotating rod 108 to rotate. The rotating rod 108 then drives the molten iron tank 107 to rotate, allowing the molten iron tank 107 to flip up and down, so that the upper and lower surfaces of the molten iron tank 107 can be used alternately.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
