[0002] The disk ingot casting machine is a commonly used metallurgical device, which can cast ingots of metals such as lead, zinc, aluminum and alloys. The disk ingot casting machine includes a disk, a casting mold placed on the disk, and a driving device for driving the disk to rotate. A liquid guide plate is placed on the top of two adjacent molds. When in use, liquid metal is supplied into the mold, and the liquid metal falling between the two molds can be guided into the mold through the liquid guide plate. The metal liquid solidifies to form a metal ingot after cooling in the mold. After the ingot casting is completed, the metal ingot needs to be demolded and then transferred.

[0003] At present, when demolding the metal ingot of the disk ingot casting machine, usually, workers need to manually remove the liquid guide plate on the mold first, and then demold the metal ingot. After the mold is reset, the liquid guide plate is reset. However, manually moving the liquid guide plate has problems such as high labor intensity of workers, high safety hazards and low production efficiency.

[0004] Correspondingly, the field needs a new avoidance device for a disk ingot casting machine to solve the above problems. Content of the Utility Model

The third guide rail is provided on the lifting seat, the third slider is provided on the connecting block, and the third slider is slidably provided on the third guide rail.

[0016] In the preferred technical solution of the avoidance device of the above disk ingot casting machine, the avoidance mechanism includes a telescopic assembly and an avoidance rod provided on the telescopic assembly. The telescopic assembly is provided on the swinging arm and is used to extend the avoidance rod to or retract it from below the liquid guide plate;

[0036] To solve the problems of high labor intensity, high safety hazards and low production efficiency for workers when manually moving the liquid guide plate.

[0037] Such as Figures 1 to 7 As shown, this embodiment discloses an automatic demoulding device for a disk ingot casting machine. The disk ingot casting machine can cast ingots of metals such as lead, zinc, aluminum and alloys. This embodiment takes lead liquid as an example for illustration. The disk ingot casting machine includes a disk ingot casting machine body 1, a plurality of molds 2 and a liquid guide plate 5. The plurality of molds 2 are evenly arranged in a circular shape on the disk ingot casting machine body 1. The cross-section of the liquid guide plate 5 is an inverted "V" shape, and the liquid guide plate 5 is placed on the tops of two adjacent molds 2.

[0038] The lead liquid flowing out of the smelting furnace is introduced into the empty mold 2 through the introduction plate or the lead extraction pump. After the lead liquid in the mold 2 reaches the set liquid level, the disk ingot casting machine body 1 rotates, moves the mold 2 with the lead liquid introduced into the next working position, and at the same time moves the empty mold 2 in. The smelting furnace continues to introduce lead liquid into the empty mold 2. During the rotation of the disk ingot casting machine body 1, the lead liquid supplied by the smelting furnace keeps flowing, and the lead liquid falling on the liquid guide plate 5 flows into the mold 2 with the lead liquid introduced or the empty mold 2 to reduce the possibility of the lead liquid flowing onto the disk ingot casting machine body 1. After the mold 2 with the lead liquid introduced is cooled naturally, the lifting lugs 4 are inserted and cooled forcibly, the casting is completed to form a lead ingot, and then it is moved to the automatic demoulding device for demoulding.

[0039] Such as Figures 1 to 7As shown in the figure, the automatic demoulding device includes a frame 6, an avoidance device 7, a transplanting device 8, and a knocking and vibrating device 9. The avoidance device 7 and the knocking and vibrating device 9 are installed on the frame 6, and the frame 6 is fixed on the transplanting device 8. Of course, the frame 6 can also be fixed to the ground separately. The avoidance device 7 is located on one side of the mold 2, and the liquid guide plate 5 is placed on the top of two adjacent molds, that is, a liquid guide plate 5 is placed on both sides of the top of each mold 2 of the lead ingot to be demoulded. Through the avoidance device 7, the two liquid guide plates 5 on the top of the mold 2 can be removed, so as to facilitate the transplanting device 8 to lift the undemoulded lead ingot. The knocking and vibrating device 9 is located above the mold 2. By knocking the upper edge of the mold 2 through the knocking and vibrating device 9, the mold 2 can be detached from the lead ingot. The detached mold 2 falls onto the ingot casting machine body and continues to move to the next station. The transplanting device 8 moves the demoulded lead ingot to a designated position, such as transferring it to a deburring station, a transfer platform or a transfer trolley, and then the transplanting device 8 resets to lift the next lead ingot to be demoulded. If the demoulding of the lead ingot fails, the control system alarms, stops the transplanting device, and manually intervenes to transfer the lead ingot with failed demoulding and replenish a new empty mold. Then, the transplanting device is controlled to make the transplanting device in the state after successful demoulding, waiting to process the next lead ingot to be demoulded. Since the manual intervention time is short, the avoidance device and the knocking and vibrating device do not need to stop, which will not affect the processing of the next lead ingot, enabling continuous production of lead ingots. Through the cooperation of the avoidance device 7, the transplanting device 8 and the knocking and vibrating device 9 to demould the lead ingot, replacing manual demoulding, it can reduce the contact between workers and lead ingots, reduce the labor intensity of workers, reduce potential safety hazards, and improve production efficiency at the same time.

[0040] As Figures 2 to 4 shown in the figure, specifically, the avoidance device 7 includes a mounting frame 74, a second lifting mechanism 71, a swinging mechanism 73, and two avoidance mechanisms 72. The mounting frame 74 is fixed on the frame 6, the second lifting mechanism 71 is installed on the mounting frame 74, and the swinging mechanism 73 is installed on the second lifting mechanism 71. The second lifting mechanism 71 can drive the swinging mechanism 73 to rise or fall. The two avoidance mechanisms 72 are both installed on the swinging mechanism 73 and are arranged corresponding to the two liquid guide plates 5 on the mold 2. One end of the avoidance mechanism 72 can extend into or out of the lower part of the liquid guide plate 5. After the avoidance mechanism 72 extends into the lower part of the liquid guide plate 5, the second lifting mechanism 71 drives the swinging mechanism 73 to rise, so that the avoidance mechanism 72 can lift the liquid guide plate 5, and then the swinging mechanism 73 drives the two avoidance mechanisms 72 to move horizontally away from the mold 2, so as to facilitate the transplanting device 8 to lift the undemoulded lead ingot.

[0041] As Figure 3 and Figure 4As shown, the second lifting mechanism 71 includes a second linear drive member 711, a lifting seat 712, at least one second slider, and a second guide rail 713. The lifting seat 712 is fixed to the output end of the second linear drive member 711. The second linear drive member 711 is fixed to the mounting bracket 74. The swing mechanism 73 is mounted on the lifting seat 712. Starting the second linear drive member 711 can drive the lifting seat 712 to lift or lower, driving the swing mechanism 73, the avoidance mechanism 72, and the liquid guide plate 5 to lift or lower synchronously, so that the liquid guide plate 5 can move away from or close to the mold 2.

[0042] In this embodiment, the number of the second sliders and the second guide rails 713 are both set to two. The second sliders are fixed to the lifting seat 712, and the second guide rails 713 are fixed to the mounting bracket 74. The second sliders are slidably disposed on the second guide rails 713 in one-to-one correspondence. By the cooperation of the second sliders and the second guide rails 713, the lifting seat 712 can be lifted or lowered more stably under the drive of the second linear drive member 711.

[0043] As Figure 3 and Figure 4 As shown, the swing mechanism 73 includes a third linear drive member 731, a connection block 732, two connection arms 733, a swing arm 734, a third guide rail 735 fixed to the lifting seat 712, and a third slider fixed to the connection block 732. The third linear drive member 731 is mounted on the lifting seat 712. The connection block 732 is fixed to the output end of the third linear drive member 731. The third slider is slidably disposed on the third guide rail 735. Starting the third linear drive member 731 can drive the connection block 732 to move in a direction away from or close to the mold 2. The connection arms 733 and the swing arms 734 are arranged in one-to-one correspondence. One end of the connection arm 733 is hinged to the connection block 732, the other end of the connection arm 733 is hinged to the swing arm 734, and the swing arm 734 is hinged to the lifting seat 712. The avoidance mechanism 72 is fixed to the swing arm 734.

[0044] When the third linear drive member 731 drives the connection block 732 to move, the connection block 732 drives the connection arm 733 to swing, and the connection arm 733 drives the swing arm 734, so that the swing arm 734 swings around its hinge point with the lifting seat 712 as the center, thereby driving the avoidance mechanism 72 to swing in a direction away from or close to the mold 2, so that the liquid guide plate 5 can move away from or close to the mold 2 in the horizontal direction.

[0045] As Figure 3 and Figure 4As shown, the avoidance mechanism 72 includes a telescopic component 721, an avoidance rod 722, and a limiting plate 723 fixed on the avoidance rod 722. A jack 51 for the avoidance rod 722 to fit and insert is provided on the liquid guide plate 5. After the avoidance rod 722 is inserted into the jack 51, the limiting plate 723 is in contact with one end of the liquid guide plate 5. The telescopic component 721 includes a fourth linear driving member 7211 and a connecting rod 7212 fixed at the output end of the fourth linear driving member 7211. In this embodiment, the fourth linear driving member 7211 is a rodless cylinder, and the rodless cylinder is installed on the swing arm 734. The avoidance rod 722 is fixedly connected to the liquid guide plate 5. The avoidance rod 722 can be driven to insert into the jack 51 or pulled out from the jack 51 by the fourth linear driving member 7211.

[0046] When the lead ingot to be demolded moves to the automatic demolding device, start the fourth linear driving member 7211 to insert the avoidance rod 722 into the jack 51, and then start the second linear driving member 711 to drive the lifting seat 712 to rise, driving the swing device, the telescopic component 721, and the avoidance rod 722 to rise, so that the liquid guide plate 5 moves away from the mold 2 in the vertical direction. Then start the third linear driving member 731 to drive the connecting block 732 to move, the connecting block 732 drives the connecting arm 733 to swing, driving the swing arm 734 to swing, thereby driving the telescopic component 721 and the avoidance rod 722 to move away from the mold 2, enabling the two liquid guide plates 5 on the top of the mold 2 to move away from the mold 2 in the horizontal direction and removing the liquid guide plates 5. At this time, the two liquid guide plates 5 are not directly above the mold 2, which can reduce the possibility that the liquid guide plates 5 affect the hoisting of the lead ingot by the transplanting device 8 and the successfully demolded mold 2 falling back onto the disk ingot casting machine body 1.

[0047] After the successfully demolded mold 2 falls back onto the disk ingot casting machine body 1, start the third linear driving member 731 to drive the connecting block 732 to reset, so that the avoidance rod 722 and the liquid guide plate 5 are reset directly above the mold 2. Then start the second linear driving member 711 to drive the lifting seat 712 to descend, so that the liquid guide plates 5 on both sides descend to fit with the mold 2. Then start the fourth linear driving member 7211 to reset, so that the avoidance rod 722 is withdrawn from the jack 51 and moves to one side of the swing arm 734 to not affect the movement of the mold 2, thereby enabling the liquid guide plate 5 to be reset. By using the avoidance device 7 to replace manual movement of the liquid guide plate 5, manual operation can be reduced, potential safety hazards can be lowered, and production efficiency can also be improved.

[0048] As Figure 2 、 Figure 3 、 Figures 5 to 7As shown, after the avoidance device 7 removes the two liquid guide plates 5, the transplanting device 8 is activated to lift the lead ingot to be demolded. The transplanting device 8 includes a truss 81, a translation mechanism 82, a first lifting mechanism 83, and a hook 84. The truss 81 includes a bracket 811 and a cross beam 812 fixed on the bracket 811, and the bracket 811 is fixed on the ground. The translation mechanism 82 is installed on the cross beam 812, and the first lifting mechanism 83 is installed on the translation mechanism 82. The translation mechanism 82 drives the first lifting mechanism 83 to move, so that the hook 84 can extend into the lifting lug 4, and then the first lifting mechanism 83 is activated to lift the lead ingot to be demolded. The lead ingot is demolded by knocking the mold 2 with the knocking device 9, and then the translation mechanism 82 drives the first lifting mechanism 83 to move, moving the successfully demolded lead ingot to the designated position. Then the first lifting mechanism 83 resets, and the translation mechanism 82 resets, preparing to lift the next lead ingot to be demolded.

[0049] As Figure 3 , Figure 5 and Figure 6 shown, the translation mechanism 82 includes a sliding seat 821 and a translation driving assembly 822. The first lifting mechanism 83 is installed on the sliding seat 821. A plurality of pulley groups are installed on the sliding seat 821. The sliding seat 821 is placed on the cross beam 812, and the pulley groups are in contact with the cross beam 812. The pulley groups can reduce the friction between the sliding seat 821 and the cross beam 812. The translation driving assembly 822 can drive the sliding seat 821 to move reciprocally, so that the first lifting mechanism 83 and the hook 84 move synchronously.

[0050] The translation driving assembly 822 includes a translation motor 8221, a transmission assembly, and at least one first driving assembly. In this embodiment, the number of the first driving assemblies is taken as two for illustration. One ends of the two first driving assemblies are connected to the sliding seat 821, and the other ends are connected to the transmission assembly. The translation motor 8221 is installed on the sliding seat 821, and the transmission assembly is installed on the sliding seat 821 and is in transmission connection with the translation motor 8221. Starting the translation motor 8221 can drive the transmission assembly, so that the transmission assembly drives the first driving assembly. Through the first driving assembly, the sliding seat 821 can be moved, driving the first lifting mechanism 83 and the hook 84 to move synchronously.

[0051] As Figure 5 and Figure 6As shown in the figure, the transmission assembly includes a rotating shaft 82231, a volute 82232, a worm gear 82233, and a worm 82234. The volute 82232 is fixed on the sliding seat 821. The worm 82234 is coaxially connected to the output shaft of the translation motor 8221 and extends into the volute 82232. The worm gear 82233 is coaxially connected to the rotating shaft 82231, and both ends of the rotating shaft 82231 extend out of the volute 82232 and are rotatably connected to the volute 82232. The worm gear 82233 meshes with the worm 82234. The first driving assembly includes a first gear 82221 and a first rack 82222. The first gear 82221 is coaxially connected to the rotating shaft 82231, and the first rack 82222 is fixed on the cross beam 812. The first gear 82221 meshes with the first rack 82222. By driving the worm 82234 to rotate through the translation motor 8221, the worm gear 82233 drives the rotating shaft 82231 to rotate. The rotating shaft 82231 drives the two first gears 82221 to rotate. Since the first rack 82222 is fixed on the cross beam 812 and the sliding seat 821 is slidably mounted on the cross beam 812, the sliding seat 821 can be moved along the length direction of the rack, and further the first lifting mechanism 83 and the lifting lug 4 can be moved. By controlling the rotation direction of the translation motor 8221, the moving direction of the sliding seat 821 can be changed.

[0052] Of course, the translation motor 8221 and the volute 82232 can also be fixed on the cross beam 812. Both ends of the rotating shaft 82231 are rotatably connected to the cross beam 812. The first gear 82221 is coaxially connected to the rotating shaft 82231, and the first rack 82222 is fixed on the sliding seat 821. By driving the worm 82234 to rotate through the translation motor 8221, the worm gear 82233 drives the rotating shaft 82231 to rotate. The rotating shaft 82231 drives the two first gears 82221 to rotate, and the first gear 82221 drives the rack to move, which can also drive the sliding seat 821 to move, so that the first lifting mechanism 83 and the lifting lug 4 can be moved.

[0053] Such as Figure 3 、 Figure 5 and Figure 7As shown, the first lifting mechanism 83 includes a lifting block 831 and a lifting drive assembly. Since the weight of lead ingots is usually relatively heavy, in order to enable the lifting block 831 to lift and lower more stably, two lifting drive assemblies are provided in this embodiment and are symmetrically arranged. The lifting drive assembly includes a lifting motor 8321 and a second drive assembly. The second drive assembly includes a second gear 83221 and a second rack 83222. The lifting motor 8321 is installed on the sliding seat 821. The second gear 83221 is coaxially connected to the output shaft of the lifting motor 8321. The second rack 83222 is fixed on the lifting block 831. The second gear 83221 meshes with the second rack 83222. By driving the second gear 83221 to rotate with the lifting motor 8321, the second rack 83222 can drive the lifting block 831 to rise or fall, so as to lift or lower the lead ingot.

[0054] As Figure 2 and Figure 7 shown, further, the transplanting device 8 further includes a weighing mechanism 85. The weighing mechanism 85 includes a weighing member 851, a connecting plate 852, a plurality of pull rods 853, and a stop block 854 fixed to one end of the pull rod 853. The end of the pull rod 853 away from the stop block 854 slidably penetrates through the connecting plate 852 and is fixed to the lifting block 831. The connecting plate 852 can be guided by the pull rod 853. One end of the weighing member 851 is fixed to the lifting block 831, and the other end is fixed to the connecting plate 852. The hook is fixed to the side of the connecting plate 852 facing away from the weighing member 851. After the hook lifts the lead ingot, the weight of the lead ingot can be measured by the weighing member 851, and the weight information is transmitted to the control system of the automatic demoulding device to determine whether the lead ingot is successfully demoulded. The weighing member 851 is a commonly used weighing sensor in the art and will not be elaborated here.

[0055] After the avoidance device 7 removes the two liquid guide plates 5, start the translation motor 8221 to drive the sliding seat 821 to move, so that the lifting hook 84 can extend into the lifting lug 4. Then start the lifting motor 8321 to drive the lifting block 831 to rise by a second preset height, and start the knocking and vibrating device 9 to knock the mold 2. A plurality of position sensors are installed on the disk ingot casting machine body 1 to detect whether the mold 2 returns to its position. After detecting that the mold 2 returns to its position, that is, after the mold 2 falls off onto the disk ingot casting machine body 1, stop the knocking and vibrating device 9 and weigh the lead ingot.

[0056] If it is less than the preset weight, the preset weight can be determined according to the sum of the weight of the lead ingots in this batch and the weight of the mold 2. If the lead ingots are successfully demolded, if it is not less than the preset weight, it is determined that the lead ingots are demolded unsuccessfully. Or after the knocking and vibrating device 9 knocks the mold 2 for the second preset time period and the return of the mold 2 is still not detected, stop the knocking and vibrating device 9 and weigh the lead ingots. If it is less than the preset weight, it is determined that the lead ingots are successfully demolded. If it is not less than the preset weight, it is determined that the lead ingots are demolded unsuccessfully. If the return of the mold 2 is detected but the demolding is determined to be unsuccessful, or the return of the mold 2 is detected but the demolding is determined to be successful, the control system alarms and the operator repairs the position sensor and the weighing member 851.

[0057] As Figure 2 and Figure 7 As shown, the knocking and vibrating device 9 includes at least one knocking and vibrating mechanism 91 and an adjusting mechanism 92. In this embodiment, the number of the adjusting mechanisms 92 is taken as two for example, and the number of the knocking and vibrating mechanisms 91 is taken as three for example. Two of the knocking and vibrating mechanisms 91 are installed on one adjusting mechanism 92, and the other knocking and vibrating mechanism 91 is installed on the other adjusting mechanism 92. And the three knocking and vibrating mechanisms 91 are not on the same horizontal line. Preferably, the three knocking and vibrating mechanisms 91 are arranged in a triangle. When in use, two of the knocking and vibrating mechanisms 91 arranged diagonally are started, and the other knocking and vibrating mechanism 91 is reserved. This setting method can make the mold 2 fall off faster. The distance between the knocking and vibrating mechanism 91 and the mold 2 can be adjusted through the adjusting mechanism 92 so that the knocking and vibrating mechanism 91 is applicable to molds 2 of different heights. Of course, the adjusting mechanism 92 may not be provided, and only the distance between the mold 2 and the knocking and vibrating mechanism 91 is adjusted by relying on the transplanting device 8. Only the distance between the bottom of the mold 2 of different heights and the body of the transplanting device 8 will change, and the applicable height of the mold 2 will be reduced without affecting the demolding effect of the lead ingots.

[0058] The adjusting mechanism 92 includes a first linear driving member 921, a mounting plate 922, a first slider 924 fixed on the mounting plate 922, and a first guide rail 923 fixed on the frame 6. The first slider 924 is slidably arranged on the first guide rail 923. The first linear driving member 921 is installed on the frame 6, the mounting plate 922 is fixed on the output end of the first linear driving member 921, and the knocking and vibrating mechanism 91 is installed on the mounting plate 922. By starting the first linear driving member 921, the mounting plate 922 can be driven to rise or fall, driving the knocking and vibrating mechanism 91 to rise or fall to adjust the distance between the knocking and vibrating mechanism 91 and the mold 2.

[0059] As Figure 2 and Figure 7As shown, the knocking mechanism 91 includes a control component, a driving component, and a knocking component. The control component can control the start / stop and operating parameters of the driving component. The driving component is used to drive the knocking component to knock the mold 2. In this embodiment, the control component is a controller, the driving component is a knocking cylinder 911, and the knocking component is a hammer head 912. The knocking cylinder 911 is installed on the mounting plate 922, and the hammer head 912 is fixed to the output end of the knocking component. The knocking cylinder 911 can drive the hammer head 912 to knock the upper edge of the mold 2, enabling the lead ingot to be demolded.

[0060] A temperature sensor is installed on the frame 6 to detect the temperature of the mold 2 of the lead ingot to be demolded and transmit the detected temperature data to the controller in real time. The controller can receive and record the intake pressure, knocking frequency, knocking duration, and mold temperature of the knocking cylinder 911 this time. The controller can also select, from the historical data of successful demolding, a data set that is close to the intake pressure, knocking frequency, knocking duration, and mold temperature of the knocking cylinder 911 this time and has the shortest knocking duration for successful demolding as the preferred data set, and output the intake pressure and knocking frequency in the preferred data set as the intake pressure and knocking frequency of the knocking cylinder 911 next time.

[0061] The control process repeats until the lead ingot is successfully demolded, that is, the mold 2 returns for feedback and the weight of the lead ingot detected by the weighing component 851 is less than the preset weight, or after knocking the mold 2 reaches the second preset duration, the controller controls the knocking cylinder 911 to stop. By the controller selecting the preferred data set and outputting the intake pressure and knocking frequency in the preferred data set as the intake pressure and knocking frequency of the knocking cylinder 911 next time, the hammer head 912 can knock the mold 2 with the corresponding pressure and frequency, so that the lead ingot can be demolded faster.

[0062] As Figure 2 and Figure 7 shown, when the transplanting device 8 hoists the lead ingot to the second preset height, the staff gives the intake pressure and knocking frequency for the first knocking of the knocking cylinder 911 according to experience, and the controller controls the knocking cylinder 911 to start, enabling the hammer head 912 to knock the upper edge of the mold 2 with the given intake pressure and knocking frequency. Then the controller selects, from the historical data of successful demolding, a data set that is close to the intake pressure, knocking frequency, knocking duration, and mold temperature of the knocking cylinder 911 this time and has the shortest knocking duration for successful demolding as the preferred data set, and outputs the intake pressure and knocking frequency in the preferred data set as the intake pressure and knocking frequency of the knocking cylinder 911 next time. The control process repeats, and the hammer head 912 knocks the mold 2 with the corresponding intake pressure and knocking frequency until it is determined that the demolding is successful or the mold 2 is knocked for the second preset duration.

[0063] By knocking and vibrating the hammer head 912 driven by a pneumatic hammer to knock and vibrate the mold 2, replacing manual knocking of the mold 2, the lead ingot can be demolded faster, the degree of manual participation can be reduced, and the demolding efficiency can be improved.

[0064] As Figures 1 to 7 shown, after determining that the lead ingot demolding is successful, start the translation motor 8221 to drive the sliding seat 821 to a specified position, such as transferring to a deburring station, a transfer platform or a transfer trolley, so as to continue to process the lead ingot. After the sliding seat 821 moves to the specified position, start the lifting motor 8321 to drive the lifting block 831 to descend, place the lead ingot at the specified position, and then the translation motor 8221 drives the sliding seat 821 to move away from the lead ingot, so that the hook 84 disengages from the lug 4. Start the lifting motor 8321 to reset the lifting block 831, and then start the translation motor 8221 to drive the sliding seat 821 to reset, waiting to lift the next lead ingot to be demolded. After determining that the lead ingot demolding fails, the control system alarms, and the operator intervenes to transfer the lead ingot with failed demolding and replenish a new empty mold, and then controls the translation motor 8221 and the lifting motor 8321 to make the transplanting device in the state after successful demolding, waiting to process the next lead ingot to be demolded.

[0065] By the cooperation of the translation motor 8221 and the lifting motor 8321 to control the hook 84 and the sliding seat 821 to lift and transfer the metal ingot 3, the operation accuracy of lifting and transferring the metal ingot 3 to the set position can be improved, the degree of manual participation can be reduced, and the production efficiency can be improved.

[0066] The disk ingot casting machine body 1 transfers the lead ingot to be demolded to the automatic demolding device, starts the fourth linear driving member 7211 to insert the avoidance rod 722 into the jack 51, starts the second linear driving member 711 to drive the lifting seat 712 to rise, starts the third linear driving member 731, and makes the avoidance rod 722 drive the liquid guide plate 5 to swing away from the mold 2, removing the two liquid guide plates 5 on the top of the mold. Then start the translation motor 8221 to drive the sliding seat 821 to move, so that the hook 84 can extend into the lug 4, and start the lifting motor 8321 to drive the lifting block 831 to rise by a second preset height. The operator gives the intake pressure and knocking frequency of the knocking cylinder 911 according to experience, starts the knocking cylinder 911, and then the controller selects the optimal data group from the historical data of successful demolding according to the received parameters, and outputs the intake pressure and knocking frequency in the optimal data group as the intake pressure and knocking frequency of the knocking cylinder 911 for the next time, so that the hammer head 912 can knock the mold 2 with the corresponding pressure and frequency. The control process is repeated in a cycle, and the hammer head 912 knocks the mold 2 with the corresponding intake pressure and knocking frequency until it is determined that the demolding is successful or the mold 2 is knocked for a second preset duration.

[0067] After the control system determines that the lead ingot demoulding is successful, it starts the translation motor 8221 to drive the sliding seat 821 to a specified position, such as transferring it to the deburring station, transfer platform or transfer trolley, so as to continue processing the lead ingot. At the same time, it starts the third linear driving member 731 to drive the connecting block 732 to reset, starts the second linear driving member 711 to drive the lifting seat 712 to descend, and starts the fourth linear driving member 7211 to reset, so that the two liquid guide plates 5 are reset. After determining that the lead ingot demoulding fails, the control system alarms, and the operator intervenes to transfer the lead ingot with demoulding failure and replenish a new empty mold. Then, it controls the translation motor 8221 and the lifting motor 8321 to make the transplanting device in the state after successful demoulding, waiting to process the next lead ingot to be demoulded. Removing the liquid guide plate 5, lifting the lead ingot, vibrating the mold 2 and transferring the lead ingot are all completed by the control system controlling the automatic demoulding device. Only when the demoulding fails, manual participation is required, which can reduce the labor intensity of workers, reduce potential safety hazards, and at the same time improve the lead ingot demoulding efficiency, thereby improving the efficiency of the entire lead ingot production process.
