Description

Technical Field

[0001] The invention relates to the technical field of machining and casting, in particular to a high-potential magnesium anode machining and casting mould. Background Art

[0002] High potential magnesium anode is a magnesium anode used for electrochemical applications. It has a high potential and is mainly used for corrosion protection and electrolysis processes. High potential magnesium anode can effectively protect metal structures and prevent corrosion in electrochemical reactions. It prolongs the service life of other metal parts by sacrificing its own magnesium. Due to the high electrochemical activity of magnesium, it can provide a stable current during the electrolysis process and is suitable for various electrochemical reactions. Magnesium has a low density and is lighter than other metal anodes, making it suitable for applications that require weight reduction.

[0003] After searching, the utility model with publication number CN220216661U includes a shell; a forming mold is fixedly connected to the inner wall of the shell, and a cooling component is arranged on one side of the shell; the cooling component includes a water outlet pipe, the water outlet pipe is fixedly connected to one side of the shell, the side of the water outlet pipe away from the shell is fixedly connected to a water tank, the inner wall of the shell is connected to the inner wall of the water tank through the water outlet pipe, a valve is fixedly connected to the outer wall of the water outlet pipe, a transmission pipe is fixedly connected to the top of the water tank, the transmission pipe is L-shaped, an annular pipe is fixedly connected to one side of the top of the transmission pipe, a water pump is fixedly connected to the top of the water tank, the water pump is arranged on one side of the transmission pipe, a connecting pipe is fixedly connected to the bottom of the annular pipe, the bottom of the connecting pipe extends into the inner wall of the shell, a nozzle is fixedly connected to the bottom of the connecting pipe, a slot is opened at the bottom of the shell, and a plug-in plate is plugged into the inner wall of the slot.

[0004] In the above utility model, an annular tube and a nozzle are used to control the direction of water flow so as to quickly cool the magnesium anode mold, and the cooperation of a hydraulic cylinder and a push block is further used to realize the demoulding and removal of the magnesium anode; however, during the water cooling process, part of the water vapor generated may be drawn into the molten magnesium liquid, and the molten magnesium liquid will react with water at high temperature to produce hydrogen, thereby reducing the quality of the casting; on the other hand, since the water cooling liquid always contacts the upper half of the side of the mold first, the top of the casting in the mold is quickly cooled and causes local overcooling. At this time, the bubbles precipitated from the bottom of the casting are more difficult to escape, resulting in bubble defects on the surface of the casting, thereby affecting the geometric shape and dimensional accuracy of the casting.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Embodiment 1:

[0034] See also Figures 1 to 9The present invention provides a technical solution: a high-potential magnesium anode processing casting mold, comprising a feeding mechanism arranged at the top of the inner top of the forming mold 1, a lifting mechanism arranged at the bottom of the feeding mechanism, a pouring mechanism arranged at the bottom of the lifting mechanism, and a cooling mechanism arranged on the outer contour of the top of the forming mold 1, the top of the forming mold 1 is fixedly connected with a fixing rod 11, the bottom of the forming mold 1 is penetrated and slidably connected with a pulling plate 12, and four centrally symmetrical limiting grooves 13 are opened on the outer contour of the top of the forming mold 1;

[0035] The feeding mechanism comprises a feeding hopper 2 fixedly connected to the top of the forming mold 1 for centralized processing of the molten magnesium liquid, and a guide pipe 21 for introducing the molten magnesium liquid is fixedly connected to the bottom end of the feeding hopper 2;

[0036] The lifting mechanism comprises a guide pipe 2 3 sleeved on the outer contour of the guide pipe 1 21 for introducing molten magnesium liquid, and a thread groove 31 is provided on the inner contour of the guide pipe 2 3;

[0037] The pouring mechanism includes a pouring frame 4 that is supported at the bottom of the guide pipe 2 3 to guide and pour the molten magnesium liquid. A transmission shaft 41 is fixedly connected to the inner walls on both axial sides of the pouring frame 4. A gear 42 is fixedly connected to one end of the transmission shaft 41 away from the pouring frame 4.

[0038] The cooling mechanism comprises a connecting rod group fixedly connected to the outer contour of the top end of the guide pipe 2 3 and a rotating roller 6 fixedly rotatably connected to the outer contour of the forming mold 1 , and the connecting rod group and the rotating roller 6 are in transmission connection.

[0039] In the present device, the lower half of the interior of the forming mold 1 serves as a casting mold for the molten magnesium liquid, and the structure of the upper half is configured to cooperate with the feeding mechanism and the cooling mechanism to reduce the contact between the molten magnesium liquid and the outside air; in the conventional direct casting process, the molten magnesium liquid collides with the bottom of the mold and splashes, causing turbulence in the molten magnesium liquid, thereby causing the outside air to be drawn into the molten magnesium liquid, resulting in an increased probability of bubble formation during the casting process.

[0040] Among them, the fixed rod 11 provides a limit for the feeding mechanism to ensure that the feeding mechanism will not deflect during operation, and the limit groove 13 also limits the cooling mechanism. When the casting process is completed, the casting is demoulded by pulling out the pull-out plate 12 and cooperating with the pouring mechanism.

[0041] The feeding mechanism is used in the present device to realize the overall drive control of the device and interfere with the injection process of the molten magnesium liquid. After the magnesium liquid is injected into the upper surface of the feed hopper 2, it flows into the guide pipe 21 along the contour of the feed hopper 2. Further, with the cooperation of the other structures of the feeding mechanism, slow feeding is realized to reduce the probability of turbulence of the magnesium liquid when it contacts the device, thereby improving the casting quality of the device.

[0042] The lifting mechanism works synchronously with the feeding mechanism, and the guide pipe 23 rises synchronously under the screw connection of the thread groove 31. At this time, the pouring mechanism located at the bottom of the guide pipe 23 rises synchronously under the pulling action of the guide pipe 23, that is, during the working process of the feeding mechanism, the lifting mechanism and the pouring mechanism are in a state of being constantly rising; and when the pouring process is completed, the feeding mechanism is driven in reverse, and the guide pipe 23 drives the pouring mechanism to descend synchronously, thereby ensuring that the distance difference between the pouring height of the pouring frame 4 and the liquid level height inside the molding mold 1 is always maintained within a constant distance, further reducing the sputtering phenomenon of the magnesium liquid during the injection process.

[0043] While the pouring mechanism is rising and falling synchronously with the guide pipe 2 3, the pouring frame 4 is able to swing back and forth laterally inside the molding mold 1 through the cooperation of the feeding mechanism, thereby ensuring that the distance difference between the pouring height of the pouring frame 4 and the liquid level height inside the molding mold 1 is always less than the sputtering threshold. The reciprocating swing of the pouring frame 4 can dynamically adjust the pouring direction, further promoting the uniform distribution of the magnesium liquid to various parts inside the molding mold 1, ensuring more sufficient filling to reduce casting defects, and at the same time, changing the injection direction can effectively avoid local overheating and uneven cooling, and reduce thermal stress caused by temperature gradients.

[0044] Furthermore, when the pouring frame 4 rises along with the material guide pipe 2 3, the material guide pipe 2 3 further drives the connecting rod group and the cooling mechanism to work synchronously. At this time, the cooling mechanism is fully unfolded and deflected along the rotating roller 6 to fit and cover the lower half of the outer surface of the forming mold 1. From the above, it can be seen that the lower half of the interior of the forming mold 1 is used as a casting mold for the molten magnesium liquid, that is, the cooling mechanism realizes a covering cooling operation of the casting inside the forming mold 1.

[0045] Embodiment 2:

[0046] See also Figure 3 - Figure 4 This embodiment further illustrates the following on the basis of the first embodiment:

[0047] A driving shaft 22 is penetrated through the center of the fixed rod 11 and is connected to it for limited rotation. A driving motor 24 is fixedly connected to the top end of the driving shaft 22. A spiral flow channel 23 is fixedly connected to and spirally surrounded on the outer contour of the driving shaft 22. A spline shaft 25 is penetrated through the bottom end of the driving shaft 22 and is transmission-connected. A return spring 26 arranged inside the driving shaft 22 is fixedly connected between the inner contour of the driving shaft 22 and the top end of the spline shaft 25.

[0048] It can be seen from the first embodiment that during the process of injecting the magnesium liquid into the device, it first contacts the feeding mechanism and controls the input rate of the magnesium liquid through the feeding mechanism to achieve slow injection. The specific working process of the feeding mechanism is as follows:

[0049] First, the drive motor 24 is turned on. The drive motor 24 drives the drive shaft 22 and the spiral flow channel 23 to rotate synchronously clockwise. At this time, the magnesium liquid injected into the upper surface of the feed hopper 2 gradually flows to the center of the feed hopper 2 under the cambered design and is introduced into the guide tube 21. Since the spiral flow channel 23 is located inside the guide tube 21, the magnesium liquid contacts the spiral flow channel 23 at this time and the connection between the feed hopper 2 and the guide tube 21 is shielded by the spiral flow channel 23. With the clockwise rotation of the spiral flow channel 23, the magnesium liquid flows slowly along the spiral flow channel 23 to achieve the purpose of slow injection.

[0050] At the same time, the rotation of the drive shaft 22 synchronously drives the spline shaft 25 and the return spring 26. During this process, due to the stiffness setting of the return spring 26, the spline shaft 25 is always inside the drive shaft 22, that is, in the subsequent lifting process, the return spring 26 is always in a stretched state to realize the reset operation of the drive shaft 22.

[0051] Embodiment three:

[0052] See also Figure 5 This embodiment further illustrates the following on the basis of the second embodiment:

[0053] The bottom end of the driving shaft 22 is fixedly connected with a transmission rod 33, and both axial ends of the transmission rod 33 are fixedly connected with the same transmission ring 32. The outer contour of the transmission rod 33 is fixedly connected with a threaded portion 34 of the same specification as the thread groove 31. The transmission rod 33 is located on the inner contour of the bottom end of the guide tube 23 and is limitedly slidably connected with the guide tube 23.

[0054] It can be seen from the second embodiment that the lifting mechanism moves synchronously while the driving shaft 22 rotates, that is, during the pouring process of the magnesium liquid, the lifting mechanism continues to rise to ensure that the distance difference between the pouring height of the pouring frame 4 and the liquid level height inside the forming mold 1 is always less than the threshold value of the magnesium liquid sputtering. The specific working process of the lifting mechanism is as follows:

[0055] When the drive shaft 22 rotates, the drive shaft 22 drives the transmission rod 1 33 and the transmission ring 1 32 to rotate synchronously. At this time, under the action of the transmission ring 1 32, the threaded position between the threaded portion 34 and the thread groove 31 changes synchronously. This process further causes the thread groove 31 and the guide tube 2 3 to rise synchronously, that is, along with the clockwise rotation of the drive shaft 22, the guide tube 2 3 is gradually retracted back to the outer contour of the guide tube 21, and the bottom end of the guide tube 2 3 always abuts against the casting frame 4, that is, the casting frame 4 rises synchronously with the guide tube 2 3, so that along with the continuous pouring process, the liquid level inside the molding mold 1 gradually increases, and the pouring height of the pouring frame 4 also increases synchronously, thereby ensuring that the distance difference between the pouring height of the pouring frame 4 and the liquid level height inside the molding mold 1 is always less than the threshold value for the splashing of the magnesium liquid.

[0056] Embodiment 4:

[0057] See also Figure 6 This embodiment further illustrates the following on the basis of the third embodiment:

[0058] The bottom end of the spline shaft 25 is fixedly connected to a transmission rod 2 43, and both axial ends of the transmission rod 2 43 are fixedly connected to the same transmission ring 2 44. The upper surface of the transmission ring 2 44 is fixedly connected to a semi-ring tooth 45, and the semi-ring tooth 45 is intermittently meshed with the missing gear 42 and is transmission-connected.

[0059] The effective tooth area of ​​the missing gear 42 accounts for one third of the total surface area of ​​the missing gear 42 , and the semi-ring teeth 45 account for one half of the total upper surface area of ​​the transmission ring 2 44 .

[0060] It can be seen from the third embodiment that, in the process of the pouring frame 4 rising synchronously with the guide pipe 2 3, the feeding mechanism synchronously drives the pouring mechanism, and at this time, the pouring mechanism realizes the reciprocating swing of the pouring frame 4 to dynamically adjust the injection direction of the magnesium liquid inside the molding mold 1. The specific working process of the pouring mechanism is as follows:

[0061] In the first stage, when the driving shaft 22 drives the spline shaft 25 to rotate, the spline shaft 25 further drives the transmission rod 2 43 and the transmission ring 2 44 to rotate synchronously, and at this time, intermittent meshing and transmission connection occur between the semi-ring teeth 45 and the missing gear 42; when the semi-ring teeth 45 rotate synchronously with the transmission ring 2 44 to the meshing position of the missing gear 42, the semi-ring teeth 45 drive the missing gear 42 to rotate synchronously, and the missing gear 42 further drives the transmission shaft 41 and the casting frame 4 to deflect, thereby realizing the unidirectional rotation of the casting frame 4 to change the casting direction of the casting frame 4 inside the molding mold 1.

[0062] In the second stage, after the missing gear 42 rotates to the maximum angle, the meshing of the missing gear 42 and the semi-ring teeth 45 is disengaged but still in contact. At this time, under the gravity of the casting frame 4 and the transmission shaft 41, the missing gear 42 has a tendency to naturally fall and rotate, and at this time, the support of the semi-ring teeth 45 on the missing gear 42 prevents the missing gear 42 from falling back, that is, under the dual effects of the gravity of the casting frame 4 and the support of the semi-ring teeth 45, the missing gear 42 is in a state of continuous knocking and vibration, and this vibration is further transmitted to the casting frame 4 through the transmission shaft 41, that is, during the casting operation of the casting frame 4, the magnesium liquid can flow into the mold more evenly by vibration, thereby improving the filling effect to reduce cold shut and defects. At the same time, the vibration can make the metal particles of the magnesium liquid more closely arranged, thereby improving the density of the casting to improve its strength and durability.

[0063] It should be noted that since the effective tooth area of ​​the missing gear 42 accounts for one-third of the total surface area of ​​the missing gear 42, that is, the maximum rotation angle of the missing gear 42 is 120°, and the semi-ring teeth 45 account for one-half of the total upper surface area of ​​the transmission ring 2 44, that is, the meshing angle between the semi-ring teeth 45 and the missing gear 42 is 180°, of which the effective meshing transmission angle is 120°, and the remaining 60° means that the missing gear 42 only contacts with the semi-ring teeth 45 without rotating with the semi-ring teeth 45, thereby ensuring the smooth progress of the first and second stages in the described process.

[0064] In the third stage, when the semi-ring teeth 45 rotate to the position where they are out of contact with the missing gear 42 on one side, the support of the semi-ring teeth 45 on the missing gear 42 disappears and it re-engages with the missing gear 42 on the other side. At this time, the transmission direction of the semi-ring teeth 45 to the missing gear 42 is opposite to the rotation direction of the missing gear 42 in the first stage. At this time, the missing gear 42 drives the transmission shaft 41 and the casting frame 4 to deflect in the opposite direction to the maximum angle again, and then further repeats the movement process described in the second stage.

[0065] In summary, during the pouring operation, the missing gear 42 realizes the reciprocating swing of the pouring frame 4 and the swing of the pouring frame 4 is accompanied by vibration transmitted by the missing gear 42, thereby promoting the uniform distribution of the magnesium liquid to various parts inside the molding mold 1, ensuring more sufficient filling to reduce casting defects, while changing the injection direction can effectively avoid local overheating and uneven cooling, and reduce thermal stress caused by temperature gradient.

[0066] It should be noted that when the guide tube 23 begins to rise under the action of the threaded portion 34 and the thread groove 31, since the reset spring 26 is always in a stretched state during the pouring process, a force analysis of the reset spring 26 shows that the deformation tension of the reset spring 26, the pressure of the guide tube 23 on the pouring frame 4 and the self-gravity of the pouring mechanism together constitute a force balance, and the self-gravity of the pouring mechanism remains unchanged. When the guide tube 23 rises, its pressure on the pouring frame 4 decreases. At this time, the reset spring 26 contracts synchronously and pulls the spline shaft 25 and the calibration mechanism as a whole to rise synchronously, thereby achieving constant contact between the guide tube 23 and the pouring frame 4; further, during the resetting process of the device, the drive motor 24 is turned on to reverse, at which time the guide tube 23 descends and resists the pouring frame 4 to descend synchronously to achieve the resetting operation.

[0067] Embodiment five:

[0068] See also Figure 7 - Figure 8 This embodiment further illustrates the following on the basis of the fourth embodiment:

[0069] The connecting rod group includes a positioning plate 5 that is penetrated and fixedly connected to the outer contour of the top end of the guide tube 2 3. The positioning plate 5 is rotatably connected to connecting rods 1 51 on all four sides through pins. The end of the connecting rod 1 51 away from the positioning plate 5 is rotatably connected to connecting rod 2 52 through a pin. The connecting rod 1 51 is slidably connected to the inside of the limiting groove 13.

[0070] The four rotating rollers 6 are all axially rotatably connected to the middle part of the outer contour of the forming mold 1, and the outer contour of the rotating rollers 6 is fixedly connected with an electric cooling plate 61, and the interior of the electric cooling plate 61 is penetrated by circuit tubes 62 at equal intervals and fixedly connected, and the side of the electric cooling plate 61 away from the forming mold 1 is limitedly rotatably connected to the end of the connecting rod 2 52 away from the connecting rod 1 51 through a pin shaft.

[0071] The connection points of the four circuit tubes 62 are provided with electrical contacts and are mutually clamped. The four circuit tubes 62 are electrically connected to each other and together form a spiral upward series circuit.

[0072] It can be seen from the first embodiment that during the pouring process, the cooling mechanism is synchronously operated with the guide pipe 2 3 to achieve full coverage of the lower half of the outer surface of the forming mold 1, and the lower half of the interior of the forming mold 1 is used as a casting mold for the molten magnesium liquid, so that the cooling operation of the forming mold 1 can be effectively completed through the full coverage of the cooling mechanism. The specific working process of the cooling mechanism is as follows:

[0073] When the guide tube 2 3 drives the positioning plate 5 to rise synchronously, the connecting rods 1 51 and 2 52 around the positioning plate 5 are synchronously extended and push the electric cooling plate 61 to deflect along the rotating roller 6. At this time, the connecting rod 1 51 cannot rotate the positioning plate 5 under the limiting action of the pull-out plate 12, and the positioning plate 5 further limits the guide tube 2 3, thereby ensuring that the guide tube 2 3 will not rotate along with the threaded portion 34 under the action of the thread groove 31, thereby effectively ensuring the working process of the lifting mechanism.

[0074] When the guide tube 2 3 rises to the limit position, it means that the pouring operation is completed. At this time, the electric cold plate 61 fully covers the lower half of the outer surface of the molding mold 1 under the driving action of the connecting rod 2 52, and the circuit tubes 62 contact each other and complete the circuit connection.

[0075] As the electric cold plate 61 achieves full coverage of the lower half of the outer surface of the forming mold 1, the circuit of the circuit tube 62 is turned on. Under the action of the current, the electric cold plate 61 starts to work and achieves uniform cooling; the interior of the electric cold plate 61 is pre-evenly filled with phase change material, specifically stearic acid with high phase change latent heat and good thermal conductivity. The phase change temperature threshold of stearic acid is 60°C, which can effectively absorb the heat diffused by the magnesium liquid inside the forming mold 1 while avoiding premature phase change. When the electric cold plate 61 achieves full coverage of the lower half of the outer surface of the forming mold 1, when the circuit of the circuit tube 62 is turned on, the stearic acid filled in the electric cold plate 61 begins to change phase and transforms from solid to liquid, and at this time, the heat diffused from the magnesium liquid inside the forming mold 1 can be effectively absorbed.

[0076] It should be noted that since the circuit of the circuit tube 62 is set in series, that is, during the deflection of the electric cold plate 61 along the rotating roller 6, even if the circuit tube 62 close to one end of the rotating roller 6 is connected in advance, the overall circuit of the circuit tube 62 will not be turned on, thereby avoiding abnormal opening of the cooling mechanism during the pouring operation.

[0077] Furthermore, since the circuit of the circuit tube 62 is arranged in a spiral upward form, that is, for the stearic acid inside the electric cold plate 61, its phase change transformation process is also from bottom to top, and the stearic acid located at the bottom of the electric cold plate 61 first undergoes a transformation process from solid to liquid, that is, for the second cooling mechanism, its cooling process of the casting inside the molding mold 1 is also from bottom to top, and the cooling from bottom to top can make the bottom of the casting cool first, avoiding local overcooling caused by rapid cooling of the top, thereby achieving a more uniform cooling process; this cooling method can effectively reduce the internal stress caused by the temperature gradient, thereby reducing the deformation and crack risks of the casting, and at the same time, uniform cooling helps to reduce the formation of bubbles and gas inclusions, thereby improving the overall quality of the casting.

[0078] It should be noted that when the cooling operation is completed, the casting inside the molding die 1 has been molded and needs to be taken out. At this time, the pull-out plate 12 at the bottom of the molding die 1 is pulled out and the drive motor 24 is turned on to reverse. The counterclockwise rotation of the drive motor 24 drives the guide tube 23 and the pouring frame 4 to descend synchronously. At this time, the pouring frame 4 further abuts against the top of the molded casting and pushes the casting to descend synchronously. Since the pouring frame 4 is in a horizontal state under the abutment of the molded casting, that is, the contact between the missing gear 42 and the semi-ring teeth 45 is disengaged at this time, the pouring frame 4 will not swing. Under the pushing action of the pouring frame 4 on the molded casting, the molded casting is removed along the bottom end of the molding die 1 to complete the demolding operation of the device.
