Description

Technical Field

[0001] This invention relates to the field of gypsum composite core mold production technology, and specifically discloses an integrated gypsum composite core mold production device and method. Background Technology

[0002] Plaster composite core molds are specialized molds for the vacuum forming industry, made primarily from plaster powder. They are manufactured through processes such as mixing, casting, and hardening. Primarily composed of plaster powder, they may contain retarders, pigments, and other modifying materials to improve properties such as wear resistance and hardness. Widely used in architectural decoration (e.g., plaster molding molds), sanitary ceramics production, and other applications, they must comply with national industrial standards.

[0003] When producing plaster composite core molds, the cylindrical outer shell needs to be placed on the plaster pouring device, and then the mixed plaster is poured into the outer shell until it is full. After that, it is left to cool. However, since the plaster composite core mold itself has a certain height, the water inside needs to evaporate during cooling and solidification. If it is poured directly in one go, it will cause obstruction of water vapor flow between the plaster, increase the time required for cooling and solidification, and reduce the production efficiency of plaster composite core molds. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide an integrated gypsum composite core mold production device and method to solve the problem that excessive gypsum pouring at one time leads to a prolonged solidification time, which is not conducive to material handling and unloading, and reduces the production efficiency of gypsum composite core molds.

A support rod is installed on the bottom of the pressure sensor 2, and the pressure sensor 2 is connected to the controller through wires.

[0014] Furthermore, the production method based on the integrated plaster composite core mold is as follows: S1. Feeding and foam board placement: The iron sheet is rolled into a cylindrical iron drum using a plate rolling machine. The iron drum is then placed on the five conveyor belts of the feeding mechanism. As the four drive motors drive the five conveyor belts to rotate, the iron drum is transported to the one conveyor belt of the transmission mechanism. Then, the one multi-axis robotic arm drives the one electric gripper to grab the foam board from the outside and accurately place it on the raised edge in the middle of the inner cavity of the iron drum, thereby separating the upper and lower spaces inside the iron drum. S2. Positioning and weighing before the first pouring stage: The iron drum moves with conveyor belt 1 to the gap between conveyor belt 2 and conveyor belt 3, that is, the iron drum falls on U-shaped frame 2. Then, linear drive module 1 starts, driving U-shaped frame 2 to rise, so that the iron drum is removed from the surface of the conveyor belt. Pressure sensor 1 monitors the weight of the iron drum in real time and feeds it back to the controller. At the same time, linear drive module 2 drives the two side clamps to move towards each other, clamping the two sides of the iron drum to ensure that it remains stable during lifting and pouring. S3, First stage of gypsum pouring: The controller controls the linear drive module three to lower the hopper according to the data of pressure sensor one, so that the discharge pipe two at the bottom of the hopper is aligned with the opening at the top of the iron drum. The solenoid valve and the delivery pump are opened to pump the gypsum slurry after stirring in the storage tank to the hopper. It is then injected into the upper space of the iron drum through the discharge pipe two. During the pouring process, pressure sensor one continuously weighs the slurry. When the pouring volume reaches about one-third of the iron drum's volume, the solenoid valve is closed to stop the pouring. S4. First stage of solidification and conveying: After the pouring is completed, the second U-shaped frame slowly descends, allowing the iron bucket to fall back onto the second conveyor belt. The second conveyor belt starts and conveys the iron bucket to the fourth conveyor belt. The conveying process takes 3-4 minutes, during which the poured gypsum is initially solidified. S5. Solidification Detection and Turning: When the iron drum travels on conveyor belt four to below U-shaped frame three, linear drive module four drives the support rod to press down. Pressure sensor two detects the surface hardness of the plaster to determine whether it has solidified. If it has solidified, the conveying continues. If it has not solidified, the conveying is paused and the drum is left to solidify. Subsequently, multi-axis robotic arm two drives electric gripper two to hold the iron drum and turn it 180° so that the end with the plaster is facing down. S6. Second stage of pouring: The overturned iron drum is conveyed by conveyor belt four to the U-shaped frame two between conveyor belt two and conveyor belt three on the other side. The positioning, weighing and clamping operations of step S2 are repeated. The hopper descends again and is aligned with the opening of the iron drum to carry out the second stage of gypsum pouring until the gypsum in the iron drum fills the remaining space. S7. Second stage solidification and discharge: After the casting is completed, the iron drum is transported to conveyor belt six via conveyor belt two. During the conveying process, 3-4 minutes are reserved for the gypsum to solidify. Drive motor five drives conveyor belt six to output the gypsum composite core mold that has completed the two-stage casting to the next process or collection area.

[0015] The working principle and beneficial effects of this solution are as follows: 1. This solution divides the inner cavity of the iron barrel into two spaces, upper and lower, by setting up a foam board and adopting a segmented pouring method. First, about one-third of the volume of gypsum is poured. After it has initially solidified, it is flipped over and the remaining part is poured. This design effectively avoids the problems of long solidification time and low efficiency caused by water vapor blockage in traditional one-time pouring, significantly shortens the overall production cycle of gypsum composite core mold, and improves production efficiency. 2. As described in 1, the device integrates multiple functional units such as transmission, positioning, weighing, clamping, pouring, flipping, detection and discharge, and realizes full-process coordinated control through a central controller. Each link feeds back data in real time through sensors (such as pressure sensors and infrared sensors), driving the precise actions of actuators such as motors, linear modules, and robotic arms, realizing the full automation and intelligent operation from feeding, separating, pouring, flipping to discharge, reducing manual intervention and ensuring the consistency of production and the stability of product quality; 3. As described in point 2, a 3-4 minute natural setting time is allowed during the conveying process. This utilizes the properties of quick-setting plaster to complete the initial setting. A detection mechanism consisting of a U-shaped frame and a pressure sensor is added to automatically detect the surface hardness of the plaster before flipping, determining the degree of setting. If the setting is not met, the conveying is paused to ensure that each flipping operation is performed after the plaster has fully set. This effectively avoids plaster deformation or quality problems caused by premature flipping, thus improving the product qualification rate.

Detailed Implementation

[0019] The following detailed description illustrates the specific implementation method: Example 1 like Figures 1 to 11 As shown, an integrated gypsum composite core mold production device is disclosed, including a transmission mechanism 1. The transmission mechanism 1 includes a support beam 10, which is a ring-shaped rectangular structure, forming a transmission path with the ends adjacent to each other.

[0020] like Figure 2 and Figure 3 As shown, the support beam 10 includes two oppositely arranged arc-shaped crossbeams 110, two oppositely arranged strip-shaped crossbeams 122, two oppositely arranged strip-shaped crossbeams 133, and two oppositely arranged strip-shaped crossbeams 142. There are two sets of crossbeams 122 and 133, which are located at both ends of crossbeam 142. Crossbeams 122 and 133, as well as crossbeams 133 and 142, are connected by crossbeams 110. A crossbeam 110 is also provided at the end of crossbeam 222 away from crossbeam 333, so that the corners of the support beam 10 are all arc-shaped structures. Multiple spaced support legs are installed on the bottom of crossbeams 222, 133, and 142 to support the entire support beam 10.

[0021] The rotating roller 11 is placed inside the crossbeam 110, and there are multiple rotating rollers 11 arranged along the length of the crossbeam 110. The ends of the rotating rollers 11 are rotatably connected to the crossbeam 110. In actual use, the rotating rollers 11 are arranged in a fan shape, which facilitates the transmission of materials along the arc trajectory on the rotating rollers 11.

[0022] The first conveyor 12 is placed inside the second crossbeam 122, and the first conveyor 12 includes a first conveyor belt 120. Drive rollers are placed at both ends of the inner side of the first conveyor belt 120. The ends of the drive rollers are rotatably connected to the second crossbeam 122. A drive motor 121 is installed at one end of one of the drive rollers. The drive motor 121 is fixed on the second crossbeam 122 to provide power for the transmission of the first conveyor belt 120.

[0023] The second conveyor 13 is placed inside the third crossbeam 133, and the second conveyor 13 includes a second conveyor belt 130 and a third conveyor belt 131. The second conveyor belt 130 and the third conveyor belt 131 are arranged along the length of the third crossbeam 133. Drive rollers are provided at both ends of the inner side of the second conveyor belt 130 and both ends of the inner side of the third conveyor belt 131. The ends of the drive rollers are rotatably connected to the third crossbeam 133. A second drive motor 132 is installed at one end of a drive roller in the second conveyor belt 130 and at one end of a drive roller in the third conveyor belt 131. The second drive motor 132 is fixed on the third crossbeam 133 and provides power for the transmission of the second conveyor belt 130 and the third conveyor belt 131.

[0024] The conveyor component 3 14 is placed inside the crossbeam 4 142, and the conveyor component 3 14 includes a conveyor belt 4 140. Both ends of the inner side of the conveyor belt 4 140 are provided with drive rollers. The ends of the drive rollers are rotatably connected to the crossbeam 4 142. A drive motor 3 141 is installed at one end of one of the drive rollers. The drive motor 3 141 is fixed on the crossbeam 4 142 to provide power for the transmission of the conveyor belt 4 140.

[0025] When using, such as Figure 2 As shown, a feeding mechanism 2 is provided at one end of one of the crossbeams 110. The feeding mechanism 2 includes two parallel crossbeams 22. The ends of the crossbeams 22 are fixed to the crossbeams 110. A conveyor belt 20 is provided between the two crossbeams 22. Both ends of the inner side of the conveyor belt 20 are provided with drive rollers. The ends of the drive rollers are fixed to the crossbeams 22. A drive motor 21 is installed at one end of one of the drive rollers. The drive motor 21 is fixed on the crossbeam 22. That is, the iron bucket wound into a cylindrical shape is picked up and placed on the conveyor belt 20. Under the transmission of the conveyor belt 20, the iron bucket to be poured with gypsum can be sent to the conveyor belt 120.

[0026] like Figure 2As shown, a board placement mechanism 4 is provided on one side of the conveyor belt 120. The board placement mechanism 4 includes an electric gripper 40, which is located above the conveyor belt 120. A multi-axis robotic arm 41 is connected to the electric gripper 40 and is mounted on a mounting base 42, which is placed on the ground. After the iron bucket is placed on the conveyor belt 120 on one side of the support beam 10, the multi-axis robotic arm 41 will drive the electric gripper 40 to move and pick up the foam board placed on one side. Then, the foam board is placed on the iron bucket on the conveyor belt 120. In actual use, a raised edge is provided in the middle of the inner side of the iron bucket to support the foam board placed inside, thereby dividing the iron bucket into upper and lower spaces. Then the conveyor belt 120 continues to move and sends the iron bucket to the conveyor belt 131. It should be noted that the thickness of the foam board corresponds to one-third of the height of the iron bucket.

[0027] As conveyor belt 3131 moves, the iron drum will be transported between conveyor belt 3131 and conveyor belt 2130. It should be noted that... Figure 5 and Figure 6 As shown, a gap exists between conveyor belt 3 131 and conveyor belt 2 130. A U-shaped frame 134 is located below this gap, and a support plate 1341 is located above the U-shaped frame 134. A linear drive module 1340 is connected to the bottom of the support plate 1341, allowing the support plate 1341 to move freely up and down within the gap between conveyor belt 3 131 and conveyor belt 2 130. A pressure sensor 1349 is located at the top of the support plate 1341, and a U-shaped frame is located at the top of the pressure sensor 1349. In actual use, the bottom surface of the U-shaped frame 1344, the top surface of the conveyor belt 2 130, and the top surface of the conveyor belt 3 131 are all level. That is, the iron bucket placed between the conveyor belt 3 131 and the conveyor belt 2 130 will fall onto the U-shaped frame 1344. As the support plate 1 1341 rises, the iron bucket can be detached from the conveyor belt 3 131 and the conveyor belt 2 130, ensuring that the weight of the iron bucket is fully applied to the U-shaped frame 1344. In this way, the weight of the iron bucket can be weighed by the pressure sensor 1 1349.

[0028] Furthermore, in actual use, the linear drive module 1340 is one of an electric push rod or a cylinder. In order to improve the stability of the lifting and lowering of the support plate 1341, at least one sleeve 1342 is provided parallel to the side of the linear drive module 1340. The bottom of the sleeve 1342 is fixed on the U-shaped frame 134, and a guide shaft 1343 is built into the top of the sleeve 1342. The top of the guide shaft 1343 is fixed to the support plate 1341. Thus, when the support plate 1341 is lifted and lowered, the guide shaft 1343 can slide within the sleeve 1342 to limit the movement, ensuring that the support plate 1341 always moves linearly in the vertical direction.

[0029] It should be noted that after the iron bucket is placed on the U-shaped frame 1344, clamping plates 1346 are provided at both ends of the top of the U-shaped frame 1344. A linear drive module 1347 is connected to the side of the two clamping plates 1346 that is relatively far apart. The linear drive module 1347 is installed on the support base 1345, which is fixed to the end of the U-shaped frame 1344. This can clamp the iron bucket placed on the U-shaped frame 1344, ensuring that the iron bucket will not shake when it is raised and lowered with the U-shaped frame 1344, thus preventing the iron bucket from falling off the U-shaped frame 1344.

[0030] Furthermore, in actual use, the linear drive module 2 1347 is one of an electric push rod or a cylinder. In order to allow the two clamping plates 1346 to move stably relative to each other, at least one guide shaft 2 1348 is provided parallel to the side of the linear drive module 2 1347. One end of the guide shaft 2 1348 is fixed on the clamping plate 1346, and the other end of the guide shaft 2 1348 slides through the support base 1345 to provide guidance for the linear movement of the clamping plate 1346 and ensure the stable movement of the clamping plate 1346.

[0031] After the iron barrel is raised along with the U-shaped frame 1344, as Figure 2 and Figure 8 As shown, a pouring mechanism 5 is provided above the gap between conveyor belt 2 130 and conveyor belt 3 131. The pouring mechanism 5 includes a hopper 52. The top of the hopper 52 is fixed to the support plate 2 511 through a connecting frame 513. A linear drive module 3 510 is installed on the top of the support plate 2 511. The linear drive module 3 510 is installed on an L-shaped support frame 51, and the bottom of the support frame 51 is fixedly placed on the ground. In actual use, the linear drive module 3 510 is one of an electric push rod or a cylinder, allowing the hopper 52 to be freely raised and lowered.

[0032] In order to improve the lifting stability of the hopper 52, a guide shaft 512 is provided parallel to the side of the linear drive module 510. The bottom of the guide shaft 512 is fixed on the support plate 511, and the top of the guide shaft 512 slides through the support frame 51 to provide guidance for the lifting of the hopper 52 and ensure the lifting stability of the hopper 52.

[0033] A connecting pipe 3 507 is installed on the top of the hopper 52. A connecting pipe 2 506 is sleeved on the top of the connecting pipe 3 507. The other end of the connecting pipe 2 506 is connected to the outlet of the conveying pump 505, and the conveying pump 505 is fixed on the support frame 51. A connecting pipe 1 504 is installed on the inlet of the conveying pump 505. The other end of the connecting pipe 1 504 is placed on the bottom of the storage tank 50 and connected to the discharge pipe 1 503 of the storage tank 50. The storage tank 50 is placed on the ground, and the top of the storage tank 50 is... A feeding pipe is installed on the top, and the storage tank 50 is filled with gypsum. The conveying pump 505 will draw the gypsum in the storage tank 50 into the discharge hopper 52. A discharge pipe 2 524 is installed at the bottom of the discharge hopper 52, and a solenoid valve 527 is installed on the discharge pipe 2 524. When the iron bucket is close to the discharge hopper 52, the solenoid valve 527 can be opened to start pouring gypsum into the iron bucket. The pressure sensor 1349 can weigh the amount of gypsum poured, thereby ensuring that the amount of gypsum poured is stuck at the top of the iron bucket.

[0034] Furthermore, an infrared sensor 526 is provided on the outer bottom of the hopper 52. The infrared sensor 526 is mounted on the mounting plate 525, and the mounting plate 525 is fixed on the hopper 52, in order to identify the iron barrels passing under the hopper 52.

[0035] It should be noted that there is another method for measuring the amount of plaster cast, such as... Figure 4 and Figure 11 As shown, a fluid meter 528 is installed on the discharge pipe 2 524 to measure the gypsum passing through the discharge pipe 2 524. In actual use, after the fluid meter 528 has measured the gypsum, there is no need to lift the iron drum upwards. Therefore, in order to ensure the stability of the iron drum, the conveyor belt 2 130 and the conveyor belt 3 131 are fitted with a gap to ensure that the bottom of the iron drum has sufficient support.

[0036] Furthermore, such as Figure 10 As shown, a stirring shaft 521 is provided inside the hopper 52. The top of the stirring shaft 521 passes through the top of the hopper 52 and is connected to a drive motor 520. The drive motor 520 is fixed on the hopper 52, and the stirring shaft 521 is rotatably connected to the hopper 52. Multiple stirring blades 522 are installed at intervals on the bottom of the stirring shaft 521. Under the operation of the drive motor 520, the gypsum in the hopper 52 can be stirred to ensure that the proportion of each component of the gypsum is uniform and that no sedimentation occurs during storage in the hopper 52.

[0037] In order to increase the feeding rate of gypsum in the hopper 52, a spiral blade 523 is installed on the bottom of the stirring shaft 521. The spiral blade 523 corresponds to the discharge pipe 524 and pushes the gypsum in the bottom of the hopper 52. After the solenoid valve 527 is opened, the gypsum can flow out of the discharge pipe 524 more quickly.

[0038] It should be further explained that, since there is always a conveying stage during the pouring process in the iron drum, in order to prevent the gypsum in the storage tank 50 from settling, such as... Figure 8 and Figure 9 As shown, a stirring shaft 501 is provided inside the storage tank 50. The top of the stirring shaft 501 passes through the top of the storage tank 50 and is connected to a drive motor 500. The drive motor 500 is fixed on the top of the storage tank 50, and the stirring shaft 501 is rotatably connected to the storage tank 50. Multiple stirring blades 502 are installed at intervals at the bottom of the stirring shaft 501. Under the operation of the drive motor 500, the gypsum in the storage tank 50 can be stirred, avoiding the gypsum from remaining static for a long time and causing some components to settle or precipitate.

[0039] After the iron drum is poured at one end, the U-shaped frame 1344 will slowly descend until the bottom of the iron drum contacts the conveyor belt 130. Then the conveyor belt 130 continues to operate and sends the iron drum to the conveyor belt 140. The time required for the iron drum to be transported from the conveyor belt 130 to the conveyor belt 140 is 3-4 minutes. Since the existing plaster is quick-setting plaster, and the plaster was only poured to one-third of the volume of the iron drum in the last pour, the solidification operation can be completed in this 3-4 minute transportation time.

[0040] To ensure the plaster fully solidifies, a U-shaped frame 3 63 with an opening facing downwards is provided above one end of conveyor belt 4 140 near conveyor belt 1 120. The bottom of the U-shaped frame 3 63 is fixed to the crossbeam 4 142. A support plate 3 631 is provided on the inner side of the U-shaped frame 3 63. A pressure sensor 2 633 is provided at the bottom of the support plate 3 631. A support rod 634 is provided at the bottom of the pressure sensor 2 633. A linear drive module 4 630 is installed on the top of the support plate 3 631 and is fixed on the top of the U-shaped frame 3 63. In actual use, the linear drive module 4 630 is an electric push rod or cylinder. In this configuration, when the iron bucket passes under the support rod 634, the linear drive module 630 pushes the support rod 634 to press against the top of the plaster. The magnitude of the force fed back by the pressure sensor 633 determines whether the plaster inside the iron bucket has solidified. If the plaster has solidified, the conveyor belt 140 will continue to transport the iron bucket. If the plaster has not solidified, the conveyor belt 140 can be lifted in time to wait for the plaster to solidify before continuing to transport it. In order to prevent the support rod 634 from damaging the plaster surface during contact, a disc can be set at the bottom of the support rod 634 to reduce the pressure when the support rod 634 contacts the plaster and prevent damage to the plaster.

[0041] Furthermore, at least one guide shaft 632 is provided parallel to the side of the linear drive module 630. One end of the guide shaft 632 is fixed to the support plate 631, and the other end of the guide shaft 632 slides through the U-shaped frame 63 to provide guidance for the lifting and lowering of the support rod 634, ensuring that the support rod 634 always moves linearly in the vertical direction.

[0042] As the conveyor belt 4140 continues to transport the iron drum, when the iron drum reaches the middle area of ​​the conveyor belt 4140, a flipping mechanism 6 is provided above the conveyor belt 4140. The flipping mechanism 6 includes an electric gripper 2 62, which is located at one end of a multi-axis robotic arm 2 61. The other end of the multi-axis robotic arm 2 61 is fixed on a mounting base 2 60, which is placed on the ground. The electric gripper 2 62 will grip the iron drum from the side under the operation of the multi-axis robotic arm 2 61. Then, the multi-axis robotic arm 2 61 can lift the iron drum and flip it so that the end of the iron drum that has been filled with plaster is placed downwards.

[0043] After the iron drum is flipped over, the multi-axis robotic arm 261 places the iron drum on the conveyor belt 4140 and moves it to the conveyor belt 3131 on the other side of the support beam 10. After the iron drum is sent between the conveyor belt 3131 and the conveyor belt 2130 on the other side, the iron drum will fall into the U-shaped frame 21344. As mentioned above, the U-shaped frame 21344 will rise and fall under the operation of the linear drive module 1340, while the hopper 52 above the iron drum will descend under the operation of the linear drive module 3510. Then, plaster will be poured into the top of the iron drum until the data monitored by the pressure sensor 1349 obtains an additional value. At this time, the solenoid valve 527 on the discharge pipe 2524 will be closed, and then the iron drum will descend with the U-shaped frame 21344. The iron drum will continue to be transported along the conveyor belt 2130 to the end of the support beam 10 away from the conveyor belt 520.

[0044] like Figure 1 and Figure 2 As shown, a discharge mechanism 3 is provided at the end of the support beam 10 away from the conveyor belt 20. The discharge mechanism 3 includes two parallel crossbeams 32. The ends of the crossbeams 32 are fixed to the ends of the crossbeam 110. A conveyor belt 30 is provided between the two crossbeams 32. Drive rollers are placed at both ends of the conveyor belt 30. The ends of the drive rollers rotate with the crossbeams 32. A drive motor 31 is installed at one end of one of the drive rollers. The drive motor 31 is fixed on the crossbeam 32. In this way, the iron buckets that have been poured separately at both ends are sent out, realizing the discharge of the integrated gypsum composite core mold.

[0045] It should be noted that the time required for the iron bucket to be moved to conveyor belt 630 after the other end of the pouring is completed is 3-4 minutes. That is, the plaster poured into the iron bucket will solidify during the above-mentioned conveying process, ensuring that the plaster inside the iron bucket will not overflow due to shaking or other reasons when the iron bucket is removed from conveyor belt 630.

[0046] Specifically, a control box 7 is provided on the outside of the support beam 10. The control box 7 is mounted on a fixed frame, with the bottom of the fixed frame placed on the ground. A controller is installed inside the control box 7. In actual use, the controller is one of the following: a PLC logic controller, a control motherboard, or a control host. The controller is connected via wires to drive motor 121, drive motor 22, linear drive module 1340, linear drive module 21347, pressure sensor 1349, drive motor 31, drive motor 421, drive motor 531, and an electric gripper. The device is connected to components including a multi-axis robotic arm (40), a multi-axis robotic arm (41), a drive motor (500), a delivery pump (505), a drive motor (520), an infrared sensor (526), ​​a solenoid valve (527), a fluid meter (528), a linear drive module (510), a multi-axis robotic arm (61), an electric gripper (62), a linear drive module (630), and a pressure sensor (633), to control the paste assembly core mold production device. Additionally, a touchscreen display is installed on the outer wall of the control box 7, connected to the controller via wires for operating the paste assembly core mold production device.

[0047] Furthermore, in order to achieve intelligent operation of the entire device, robotic arms can be installed on the side of crossbeam 5 22 and crossbeam 6 32. The robotic arms are connected to the controller and are used to load and unload iron drums, eliminating the need for manual operation.

[0048] It should be noted that identification sensors are installed on the bottom of electric gripper 40, the bottom of electric gripper 62, the bottom of support plate 631, and the side of crossbeam 632. The identification sensors are connected to the controller via wires. The identification sensors are laser rangefinders that identify foam boards and iron drums so that each component can operate in a timely manner.

[0049] It should be further explained that during the transportation of the iron drum, in order to ensure that the iron drum is aligned with the discharge pipe 2 524 and the support rod 634 during pouring and turning, inclined guide plates 15 are provided on both sides of the upper part of the conveyor belt 3 131 near the end of the conveyor belt 5 20. The guide plates 15 are fixed to the crossbeam 3 133 by brackets. Inclined guide plates 2 16 are provided on both sides of the upper part of the conveyor belt 4 140 near the end of the conveyor belt 5 20. The guide plates 2 16 are fixed to the crossbeam 4 142 by brackets. The guide plates 2 16 guide the iron drum that is about to be poured and turned so that the iron drum is in the center line area of ​​the conveyor belt, which makes it easier for the iron drum to be aligned with the discharge pipe 2 524 and the support rod 634.

[0050] The method for production based on an integrated plaster composite core mold is as follows: S1. Feeding and foam board placement: The iron sheet is wound into a cylindrical iron drum using a plate rolling machine. The iron drum is then placed on the conveyor belt 20 of the feeding mechanism 2. As the drive motor 21 drives the conveyor belt 20 to rotate, the iron drum is transported to the conveyor belt 120 of the transmission mechanism 1. Then, the multi-axis robotic arm 41 drives the electric gripper 40 to grab the foam board from the outside and accurately place it on the raised edge in the middle of the inner cavity of the iron drum, thereby separating the upper and lower spaces inside the iron drum. S2. Positioning and weighing before the first stage of pouring: The iron drum moves with conveyor belt 120 to the gap between conveyor belt 2130 and conveyor belt 31, that is, the iron drum falls on U-shaped frame 21344. Then, the linear drive module 1340 starts, driving U-shaped frame 21344 to rise, so that the iron drum is removed from the surface of the conveyor belt. Pressure sensor 1349 monitors the weight of the iron drum in real time and feeds it back to the controller. At the same time, the linear drive module 21347 drives the two clamping plates 1346 on both sides to move towards each other, clamping the two sides of the iron drum to ensure its stability during lifting and pouring. S3, First stage of gypsum pouring: The controller controls the linear drive module 510 to lower the hopper 52 according to the data from the pressure sensor 1349, so that the discharge pipe 2 524 at the bottom of the hopper 52 is aligned with the upper opening of the iron drum; the solenoid valve 527 and the conveying pump 505 are opened to pump the gypsum slurry after stirring in the storage tank 50 to the hopper 52, and then inject it into the upper space of the iron drum through the discharge pipe 2 524. During the pouring process, the pressure sensor 1349 continuously weighs the gypsum. When the pouring volume reaches about one-third of the iron drum volume, the solenoid valve 527 is closed to stop the pouring. S4. First stage of solidification and conveying: After the pouring is completed, the U-shaped frame 1344 slowly descends, so that the iron bucket falls back onto the conveyor belt 130. The conveyor belt 130 starts and conveys the iron bucket to the conveyor belt 140. The conveying process takes 3-4 minutes, during which the poured gypsum is initially solidified. S5. Solidification Detection and Turning: When the iron drum moves on the conveyor belt 140 to below the U-shaped frame 63, the linear drive module 630 drives the support rod 634 to press down. The pressure sensor 633 detects the surface hardness of the plaster to determine whether it has solidified. If it has solidified, the conveying continues; if it has not solidified, the conveying is paused and the drum is left to solidify. Then, the multi-axis robotic arm 61 drives the electric gripper 62 to clamp the iron drum and turn it 180° so that the end with the plaster is facing down. S6. Second stage of pouring: The overturned iron drum is transported by conveyor belt 4 140 to the U-shaped frame 2 1344 between conveyor belt 2 130 and conveyor belt 3 131 on the other side. The positioning, weighing and clamping operations of step S2 are repeated. The hopper 52 descends again and is aligned with the opening of the iron drum to carry out the second stage of gypsum pouring until the gypsum in the iron drum fills the remaining space. S7. Second stage solidification and discharge: After the casting is completed, the iron drum is transported to the sixth conveyor belt 30 via the second conveyor belt 130. During the conveying process, 3-4 minutes are reserved for the gypsum to solidify. The drive motor 531 drives the sixth conveyor belt 30 to output the gypsum combination core mold that has completed the two-stage casting to the next process or collection area.

Feeding and foam board placement: The iron sheet is rolled into a cylindrical iron drum using a plate rolling machine. The iron drum is then placed on the five conveyor belts of the feeding mechanism. As the four drive motors drive the five conveyor belts to rotate, the iron drum is transported to the one conveyor belt of the transmission mechanism. Then, the one multi-axis robotic arm drives the one electric gripper to grab the foam board from the outside and accurately place it on the raised edge in the middle of the inner cavity of the iron drum, thereby separating the upper and lower spaces inside the iron drum. S2. Positioning and weighing before the first pouring stage: The iron drum moves with conveyor belt 1 to the gap between conveyor belt 2 and conveyor belt 3, that is, the iron drum falls on U-shaped frame 2. Then, linear drive module 1 starts, driving U-shaped frame 2 to rise, so that the iron drum is removed from the surface of the conveyor belt. Pressure sensor 1 monitors the weight of the iron drum in real time and feeds it back to the controller. At the same time, linear drive module 2 drives the two side clamps to move towards each other, clamping the two sides of the iron drum to ensure that it remains stable during lifting and pouring. S3, First stage of gypsum pouring: The controller controls the linear drive module three to lower the hopper according to the data of pressure sensor one, so that the discharge pipe two at the bottom of the hopper is aligned with the opening at the top of the iron barrel. Open the solenoid valve and the delivery pump to pump the gypsum slurry that has been stirred in the storage tank to the discharge hopper. It is then injected into the upper space of the iron drum through the discharge pipe 2. During the pouring process, the pressure sensor 1 continuously weighs the slurry. When the pouring volume reaches about one-third of the iron drum's volume, close the solenoid valve and stop the pouring. S4. First stage of solidification and conveying: After the pouring is completed, the second U-shaped frame slowly descends, allowing the iron bucket to fall back onto the second conveyor belt. The second conveyor belt starts and conveys the iron bucket to the fourth conveyor belt. The conveying process takes 3-4 minutes, during which the poured gypsum is initially solidified. S5. Solidification Detection and Turning: When the iron drum travels on conveyor belt four to below U-shaped frame three, linear drive module four drives the support rod to press down. Pressure sensor two detects the surface hardness of the plaster to determine whether it has solidified. If it has solidified, the conveying continues; if it has not solidified, the conveying is paused and the drum is left to solidify. Subsequently, multi-axis robotic arm two drives electric gripper two to clamp the iron drum and turn it 180° so that the end with the poured plaster faces down. S6. Second stage of pouring: The overturned iron drum is conveyed by conveyor belt four to the U-shaped frame two between conveyor belt two and conveyor belt three on the other side. The positioning, weighing and clamping operations of step S2 are repeated. The hopper descends again and is aligned with the opening of the iron drum to carry out the second stage of gypsum pouring until the gypsum in the iron drum fills the remaining space. S7.
