Description

Technical Field

[0001] This invention relates to the field of gravity casting technology, specifically to an intelligent casting device for precision aluminum alloy castings. Background Technology

[0002] Gravity casting is a technology that uses mold tilting to achieve stable filling of molten metal. Its core feature is that it relies on the synergistic effect of gravity and mold rotation to optimize the casting process. In actual operation, molten aluminum is manually poured into the pouring cup. However, current intelligent casting devices for precision aluminum alloy castings are not convenient for cleaning floating impurities at the tail end of the molten aluminum, which can easily cause impurities to flow into the mold. At the same time, it is not convenient to automatically control the isolation of floating impurities and cut off the molten aluminum. After traditional gravity casting is formed, the solidified molten aluminum in the pouring cup needs to be removed together. Thinner products are prone to breakage and other problems, affecting product quality. In addition, the liquid level control effect of manually pouring molten aluminum is not good.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention employs a gate guide component to automatically control the heating of the solidified molten aluminum remaining inside the gate cup during pouring. Since the solidified molten aluminum inside the gate cup contains a large amount of floating impurities, heating and melting these impurities allows them to float above the molten aluminum, making it easier for workers to remove them using scrapers or other tools. This eliminates the need for workers to remove the solidified molten aluminum from the gate cup, which could easily scratch the cup or cause burns. Simultaneously, the isolation component helps to isolate the upper impurities in the molten aluminum after addition, further preventing floating impurities from being poured into the cavity between the lower and upper molds.

[0016] The use of isolation control components ensures that impurities are isolated when molten aluminum is poured into the horizontal position of the pouring cup. Simultaneously, when the lower and upper molds rotate to guide the molten iron, the bottom of the isolation component automatically forms a flow channel, diverting the molten aluminum below and preventing floating impurities from being drawn away. It can also automatically cut off the molten aluminum flow after casting. This system can control and isolate the molten aluminum inside the pouring cup, facilitating subsequent retrieval and cleaning by workers. It avoids the traditional method of removing the molded workpiece and the solidified aluminum block inside the pouring cup together, as well as the tedious process of removing impurity layers during material recycling. This optimizes the efficiency of subsequent workpiece blank processing, features a simple structure, and allows for automatic control.

[0017] By employing limit control components, the liquid level of molten aluminum can be automatically detected and controlled, preventing insufficient addition of molten aluminum. This structure can automatically control the molten aluminum to reach the required level before proceeding with the rotational guide casting process. It can assist and prompt workers, improve the success rate of casting, and reduce problems such as defects caused by insufficient molten aluminum. Attached Figure Description

[0022] The casting mold section 1 further includes: tension springs 103, four tension springs 103 are fixedly installed on the upper mold 102 by a bracket; the upper mold 102 and the lower mold 101 are used to be installed on the upper and lower mold mounting plates of the casting machine by bolts; the gate guide component 2 includes: a pouring cup 201, an electric heating plate 2011, a retaining limit post 202 and a heating switch 203, the pouring cup 201 is fixedly installed on the lower mold 101; the pouring cup 201 is used to hold molten aluminum; the electric heating plate 2011 is embedded inside the pouring cup 201; the retaining limit post 202 has two through holes at the bottom; the two through holes on the retaining limit post 202 are used to be installed on the ground by bolts; the retaining limit post 202 has a ratchet protrusion on its side ... A heating switch 203 is fixedly installed on the positioning column 202; the heating switch 203 is pressed against the side of the pouring cup 201; the heating switch 203 is electrically connected to the electric heating plate 2011; the outside of the pouring cup 201 is provided with an asbestos heat insulation layer; the isolation component 3 includes: a swing mounting plate 301, a venting groove 3011 and an isolation electromagnet 302, the swing mounting plate 301 is rotatably installed on the upper mold 102; the swing mounting plate 301 has an L-shaped cross-section; the venting groove 3011 is opened on the swing mounting plate 301; the venting groove 3011 is higher than the aluminum liquid level; the isolation electromagnet 302 is fixedly installed on the swing mounting plate 301; the isolation electromagnet 302 is used to magnetically adhere to the top of the upper mold 102; four tension springs 10 The three ends are respectively fixedly installed on the top of the swing mounting plate 301; the two sides of the swing mounting plate 301 slide against the inside of the pouring cup 201; the bottom of the swing mounting plate 301 is fixedly attached to the inside of the pouring cup 201; the swing mounting plate 301 is used to isolate impurities. The pouring guide 2 can realize automatic control to heat the solidified aluminum residue inside the pouring cup 201 when pouring molten aluminum. Because the solidified aluminum residue inside the pouring cup 201 contains a large number of impurities floating on the upper layer, heating and melting them can make them float on the top of the molten aluminum, which is convenient for workers to remove with scrapers or other tools. There is no need for workers to take the solidified aluminum out of the pouring cup 201, which can easily scratch the pouring cup 201. 01 and cause burns. At the same time, the isolation component 3 can facilitate the isolation of the upper impurities of the molten aluminum after the addition of molten aluminum. It can further prevent floating impurities from being poured into the cavity between the lower mold 101 and the upper mold 102. The structure is simple to control. Under the control of the casting machine, when the pouring cup 201 is horizontal, the pouring cup 201 squeezes the heating switch 203. The heating switch 203 controls the electric heating plate 2011 to heat. The solidified molten aluminum remaining inside the pouring cup 201 can be remelted. The impurities float to the surface. At the same time, the bottom of the swing mounting plate 301 is fixed to the inside of the pouring cup 201 to isolate the floating impurities. At the same time, the heating can be automatically controlled to ensure normal solidification and cooling.

[0023] The isolation control component 4 includes: a counterweight swing rod 401 and an electric swing block 402. The counterweight swing rod 401 is rotatably mounted on the upper mold 102. A counterweight block is provided at the bottom of the counterweight swing rod 401. The counterweight swing rod 401 is used for vertical counterweight. The electric swing block 402 is fixedly mounted on the top of the counterweight swing rod 401. The isolation control component 4 also includes: an electric contact spring 4021. An electric contact spring 4021 is fixedly mounted on the electric swing block 402, and the electric contact spring 4021 has an arc-shaped spring structure. The isolation control component 4 also includes: an electric contact tile 403. An electric contact tile 403 is fixedly mounted on the side of the upper mold 102 by bolts, and the electric contact tile 403 has an arc-shaped structure. The two ends of the electric contact tile 403 are used to fit the electric contact spring 4021. The middle section of the electric contact tile 403 has a concave structure. The electric contact tile 403, the electric contact spring 4021, and the isolation electromagnet 302 are connected in series with a power supply.The inner side of the electrical contact tile 403 and the contact surface of the contact spring 4021 are provided with a conductive coating. An isolation control component 4 is used to work in conjunction with the isolation component 3, ensuring that the isolation component 3 keeps impurities isolated when pouring molten aluminum in a horizontal position from the pouring cup 201. Simultaneously, when the lower mold 101 and upper mold 102 rotate to guide the molten iron, an automatic flow channel is formed between the bottom of the isolation component 3 and the pouring cup 201, guiding the molten aluminum below and preventing floating impurities from being drawn away. It can also automatically control the cutting off of molten aluminum after casting and can be used to control and isolate the molten aluminum inside the pouring cup 201, facilitating subsequent work. The equipment allows for direct retrieval and cleaning, avoiding the traditional method of removing the molded workpiece and the solidified aluminum block inside the pouring cup 201 together, as well as the tedious process of removing impurities during subsequent material recycling. This optimizes the efficiency of subsequent processing of the workpiece blank. The structure is simple and can be automatically controlled. After molten aluminum is poured into the pouring cup 201, as the casting machine controls the rotation of the pouring cup 201, lower mold 101, and upper mold 102, the upper mold 102 rotates, causing the front end of the electrical contact tile 403 to move and the electrical contact spring 4021 to separate. At this time, the middle section of the electrical contact tile 403 has a concave structure and cannot be straightened. When constantly powered, the isolating electromagnet 302 can be de-energized, ceasing its magnetic attraction to the upper mold 102. This creates a gap between the swing mounting plate 301 and the pouring cup 201, allowing molten aluminum to flow normally to the pouring ports on the lower mold 101 and upper mold 102 for pouring. This controls the flow of molten aluminum from below, isolating upper impurities. Simultaneously, as the lower mold 101 and upper mold 102 rotate for pouring, the lower mold 101 no longer presses against the heating switch 203, allowing the electric heating plate 2011 to be de-energized, stopping heating without affecting subsequent cooling. As the lower mold 101 and upper mold 102 continue to rotate, the counterweight swing rod 401's weight... Under the action of the action, it remains vertical. When the contact spring 4021 is attached to the protrusion at the tail end of the contact tile 403, the contact tile 403 and the protrusion at the tail end of the contact tile 403 are energized. At this time, the isolation electromagnet 302 is energized and magnetically attracts the upper mold 102. At this time, the swing mounting plate 301 moves again to attach to the pouring cup 201, thereby isolating the molten aluminum containing a large amount of floating impurities in the tail section. After the molten aluminum cools down, the lower mold 101 and the upper mold 102 can be separated by controlling the casting machine to perform demolding. After demolding, the lower mold 101 and the upper mold 102 are closed again, and then the lower mold 101 and the upper mold 102 are controlled to return to their original positions and remain horizontal.

[0024] In Example 2, based on Example 1, the floating control component 5 includes: a floating mounting bracket 501, a liquid level switch 502, and a lifting column 503. The floating mounting bracket 501 is fixedly mounted on the pouring cup 201 by bolts; the floating mounting bracket 501 has a hexagonal hole; the liquid level switch 502 is fixedly mounted on the floating mounting bracket 501 by a bracket; the lifting column 503 is slidably inserted into the hexagonal hole on the floating mounting bracket 501, and the lifting column 503 is aligned with the liquid level switch 502; the liquid level switch 502 is used to be pressed by the lifting column 503; the liquid level switch 502 is used to control the liquid level; the floating control component 5... It also includes: a float 504, which is fixedly installed at the bottom of the lifting column 503; the float 504 is used to float on the surface of molten aluminum; the limit control component 6 includes: a sliding mounting block 601, a one-way limit block 602, a limit spring 603, and a limit electromagnet 604; the sliding mounting block 601 is fixedly installed at the bottom of the pouring cup 201; the one-way limit block 602 is slidably mounted on the sliding mounting block 601, and the end of the one-way limit block 602 has a ratchet structure; the one-way limit block 602 is inserted below the ratchet protrusion on the side of the retaining limit column 202; the limit electromagnet is fixedly mounted on the sliding mounting block 601. 604; The limiting electromagnet 604 is aligned with the tail of the one-way limiting block 602; The limiting spring 603 is fixedly installed on the one-way limiting block 602, and the other end of the limiting spring 603 is connected to the end face of the limiting electromagnet 604; The limiting electromagnet 604 is electrically connected to the liquid level switch 502. The use of the limiting control component 6 can realize automatic control and detection of the aluminum pouring level, which can avoid insufficient aluminum addition. This structure can realize automatic control to ensure that the rotation and guiding pouring molding work can only be carried out normally after the aluminum pouring addition reaches the standard. It can assist and prompt the workers, improve the pouring success rate, and reduce the risk of insufficient aluminum. This avoids the problems of molding defects caused by traditional manual transfer of molten aluminum with ladles, which makes it difficult to guarantee the amount of molten aluminum and difficult to judge with the naked eye. After the molten aluminum is poured into the pouring cup 201, the molten aluminum level inside the pouring cup 201 rises. At this time, the buoyancy of the molten aluminum inside the pouring cup 201 supports the floating shell 504, which in turn pushes the lifting column 503 to squeeze the liquid level switch 502. Only then can the limit electromagnet 604 be controlled to electromagnetically pull back the one-way limit block 602. At this time, the one-way limit block 602 is no longer limited by the thorn-shaped protrusion on the limit column 202, and the rotation of the lower mold 101 and the upper mold 102 can be normally controlled.

[0025] The working principle of this embodiment is as follows: First, the upper mold 102 and the lower mold 101 are bolted to the upper and lower mold mounting plates of the casting machine. After molten aluminum is poured into the pouring cup 201, when the casting machine controls the rotation of the pouring cup 201, the lower mold 101, and the upper mold 102, the upper mold 102 rotates, causing the front end of the electrical contact tile 403 to move and the electrical contact spring 4021 to separate. At this time, the middle section of the electrical contact tile 403 is a concave structure and cannot be properly connected to electricity. The isolation electromagnet 302 can be de-energized, and the upper mold 102 is no longer magnetically attracted, causing it to swing. A gap is created between the mounting plate 301 and the pouring cup 201, allowing molten aluminum to flow normally to the pouring ports on the lower mold 101 and upper mold 102 for pouring. This controls the flow of molten aluminum from below, isolating upper impurities. Simultaneously, as the lower mold 101 and upper mold 102 rotate for pouring, the lower mold 101 no longer presses against the heating switch 203, allowing the electric heating plate 2011 to be de-energized and heating to stop without affecting subsequent cooling. As the lower mold 101 and upper mold 102 continue to rotate, the counterweight swing rod 401 remains vertical. When connected to an electric spring... When the sheet 4021 is attached to the protruding end of the electrical contact tile 403, the electrical contact tile 403 and the protruding end of the electrical contact tile 403 are connected to electricity. At this time, the isolating electromagnet 302 is energized, magnetically attracting the upper mold 102. At this time, the swing mounting plate 301 moves again to attach to the pouring cup 201, thus isolating the molten aluminum containing a large amount of floating impurities in the tail section. After the molten aluminum cools down, the lower mold 101 and the upper mold 102 can be separated by controlling the casting machine to perform demolding. After demolding, the lower mold 101 and the upper mold 102 are closed again, and the lower mold 101 and the upper mold 102 are then controlled to close. The upper mold 102 is reset and kept horizontal to facilitate the next pouring operation. When the pouring cup 201 is horizontal, the pouring cup 201 presses the heating switch 203, which controls the electric heating plate 2011 to heat. The solidified aluminum residue inside the pouring cup 201 can be remelted. Impurities float to the surface. After the workers remove most of the impurities with tools such as scrapers, the remaining small amount of impurities are fixed to the inside of the pouring cup 201 by the bottom of the swing mounting plate 301 to isolate the floating impurities. The operation is simple and quick. After molten aluminum is poured into the pouring cup 201, the molten aluminum level inside the pouring cup 201 rises. At this time, the buoyancy of the molten aluminum inside the pouring cup 201 supports the floating shell 504, which in turn pushes the lifting column 503 to squeeze the liquid level switch 502. Only then can the limit electromagnet 604 be controlled to pull back the one-way limit block 602 and compress the limit spring 603. At this time, the one-way limit block 602 is no longer limited by the ratchet protrusion on the retention limit post 202, and can normally control the rotation of the lower mold 101 and the upper mold 102. At the same time, after completing one casting, when the lower mold 101 and the upper mold 102 are rotated and reset to a horizontal position, the one-way limit block 602 is driven to reset again. Using the inclined structure at the end of the one-way limit block 602, in conjunction with the ratchet protrusion on the side of the retention limit post 202, it can slide and lock under the ratchet protrusion on the side of the retention limit post 202 for limiting.
