[0001] This utility model relates to the field of hydraulic press powder pressing and demolding technology, and in particular to a dual mold device control system for automatic feeding and demolding. Background Technology

[0002] It is well known that hydraulic presses can compress powder into shapes, but the loading and unloading of materials rely on manual labor. During loading, the powder can pose a health hazard. After pressing, the pressed product is difficult to remove from the mold, requiring manual demolding. Demolding involves removing the entire mold, lifting it out, and then dismantling the mold frame. This demolding process involves significant force, which can damage the product, increases labor costs, and is inefficient. After demolding, reassembling the mold frame, loading more material, and pressing again further increases production time.

[0003] The purpose of this invention is to solve the problems existing in the prior art by proposing a dual mold device control system for automatic feeding and demolding, which can achieve automatic feeding, automatic demolding, cyclic pressing of products, reduce labor costs, and improve production efficiency.

The several nozzles are connected to a storage tank for storing release agent through the hose. The rotating spraying device can rotate around the base. The rotating spraying device is controlled by the robot control system to facilitate spraying release agent onto the mold device 4 and ensure that the release agent that can be sprayed can cover the inside of the square mold cavity 43 in the mold device 4.

[0018] The motor control system, heating control system, hydraulic control system, demolding control system and robot control system are all integrated in the electrical cabinet 6 and can be controlled by the control panel 7.

[0019] In this embodiment, the hydraulic press is used to press powder. Through the above technical solution, the feeding device 8 can automatically feed the powder, the pushing device 9 can level the powder, the first mold device 4a and the second mold device 4b can perform pressing operations in a cycle. After the finished product is pressed out and demolded by the demolding mechanism 3, the second robot can grab the finished product and leave the demolding mechanism 3.

[0020] Example 2, the demolding mechanism 3 includes: Supporting framework 31: such as Figures 4-5 As shown, the support frame 31 includes a support frame 31, mounting blocks, connecting plates 311, load-bearing blocks 312, and connectors 314. The support frame 31 is formed by several horizontal and vertical columns. The bottom of the support frame 31 is provided with mounting blocks fixed to the ground. A reinforcing plate can also be fixedly installed at the front end of the support frame 31 to increase the strength of the support frame 31. The upper part of the support frame 31 is fixed with a connecting plate 311. Connectors 314 are respectively provided on both sides of the connecting plate 311 near the hydraulic press. The two connectors 314 are fixedly connected to the hydraulic press. On both sides of the upper plane of the connecting plate 311 away from the hydraulic press, mold stop columns 315 are respectively provided. Mold stop blocks 316 are provided at the top of the two mold stop columns 315. Load-bearing blocks 312 are symmetrically provided at the bottom of the support frame 31. Guide grooves 313 are provided on the short sides of both sides of the support frame 31. The mounting block is fixed to the ground with bolts, and the connecting body is fixed to the hydraulic press with bolts, which ensures the stability between the support frame 31 and the hydraulic press. The guide groove 313 is set at a height higher than the connecting plate 311 to facilitate the sliding of the mold device.

[0021] Ejection mechanism 32: such as Figure 6 and Figure 6-1 As shown, the ejection mechanism 32 is installed within the support frame 31 and includes a lower main cylinder 321, an ejection block 322, ejector rod 323, a secondary ejection cylinder 324, a secondary ejection block 325, and ejector rod 326. The lower main cylinder 321 is mounted through the support block 312. An ejection block 322 is positioned above the movable end of the lower main cylinder 321. A secondary ejection cylinder 324 is fixedly mounted in the middle of the ejection block 322. Multiple ejector rods 323 extending upwards are symmetrically arranged on both sides of the ejection block 322. In this embodiment, there are four ejector rods. A secondary ejection block 325 is positioned above the movable end of the secondary ejection cylinder 324. Block 325 and ejector block 322 are vertically parallel and corresponding. Multiple upward-extending ejector rods 326 are provided on the secondary ejector block 325. In this embodiment, there are three ejector rods 326. Two of the ejector rods 323 are slidably disposed through the secondary ejector block 325. A guide rod 327 is provided through the connection between the bearing block 312, ejector block 322, secondary ejector block 325 and connecting plate 311. A nut is provided on the upper end of the guide rod 327 for limiting. A nut is also provided on the lower end of the bearing block 312 for limiting the guide rod 327 to prevent the guide rod 327 from moving up and down.

[0022] To ensure smoother movement of the push rod 323 on the secondary ejector block 325, a lubrication sleeve 328 is fixedly installed where the push rod 323 penetrates the secondary ejector block 325. The lubrication sleeve 328 serves as a guide and lubricant, allowing the push rod 323 to slide within the lubrication sleeve 328. A lubrication sleeve 328 is also fixedly installed where the connecting plate 311 is penetrated by the push rod 323 and the second push rod 326. The installation of the lubrication sleeve 328 makes the sliding of the push rod 323 and the second push rod 326 smoother.

[0023] Mold device 4: Reference Figure 3 The mold device 4 is slidably disposed within the guide groove 313 at the upper end of the support frame 31. (Continuing to refer to...) Figure 7 and Figure 7-1 It includes a lower mold base plate 41, a lower mold ejector plate 44, and a square mold cavity 43. The short sides of the support frame 31 are provided with guide grooves 313 for the lower mold base plate 41 to slide. The upper surface of the lower mold base plate 41 is provided with a hollow square mold cavity 43, and the lower mold ejector plate 44 is provided inside the square mold cavity 43.

[0024] like Figure 5As shown, the guide groove 313 facilitates the sliding out of the mold device 4 and serves as a guide for the mold device 4. In actual use, the lower mold base plate 41 slides back and forth in the guide groove 313. When demolding, the guide groove 313 also exerts a reverse pulling force on the lower mold base plate 41. The top of the two mold stop pillars 315 is provided with mold stop blocks 316 that restrict the movement of the lower mold base plate 41. When the lower mold base plate 41 moves out, the mold stop blocks 316 will restrict the position of the lower mold base plate 41, making the position of the lower mold base plate 41 more accurate.

[0025] The power output device 5 of the moving mold device 4: (Refer to) Figure 8 The system includes a motor 51, a gear rack 52, a guide rail 53, a gear shaft, and a gear. The guide rails 53 are symmetrically arranged on the lower end face of the lower mold base plate 41. One end of each guide rail 53 is fixedly connected to the side of the lower heating plate 23, and the other end is supported by a telescopic support column. The telescopic support column extends downward through the connecting plate 311 to the ground. Two parallel gear racks 52 are symmetrically arranged on the outer side of the two guide rails 53. The two gear racks 52 are fixedly connected to the lower mold base plate 41 and mesh with the gear. The gear is sleeved on both ends of the gear shaft. The gear shaft is connected to the output end of the motor 51 and passes through the two connecting bodies 314.

[0026] In this embodiment, ball bearings are installed inside the guide rail 53 to facilitate the rolling of the mold device 4. A gear protective cover is installed outside the gear to protect it. Two connecting bodies 314 are arranged between the two gears, and two guide rails 53 are arranged between the two connecting bodies 314. Thus, when the motor 51 rotates, it drives the gear to rotate, and the gear then drives the gear rack 52 to move. Since the gear rack 52 is fixed on the lower mold base plate 41, the lower mold base plate 41 can be moved towards the hydraulic press 2. The lower heating plate 23 is provided with corresponding grooves for the gear rack 52 to pass through. In this scheme, the motor 51 is a geared motor. Through the above scheme, the power output device 5 is started, and the mold device 4 can move back and forth stably within the guide grooves on the hydraulic press 2 and the support frame 31.

[0027] like Figure 6 and Figure 7-1As shown, the lower mold base plate 41 is provided with a first ejection hole 42 that cooperates with ejector pin 1 323 and ejector pin 2 326. In a static state, the top ends of ejector pin 1 323 and ejector pin 2 326 will not exceed the lower mold base plate 41. In this embodiment, the length of ejector pin 1 323 is set to be longer than the length of ejector pin 2 326, and the upper ends of ejector pin 1 323 and ejector pin 2 326 are flush. When ejector pin 1 323 and ejector pin 2 326 are acted upon by the lower main cylinder, they will extend out of the first ejection hole provided on the lower mold base plate 41. In this embodiment, there are six top rings. The bottom of the top ring 45 is provided with a second ejection hole 46 that cooperates with ejector pin 2 326. Ejector pin 2 326 extends out from the first ejection hole provided by the secondary ejection cylinder. The second ejector hole 46 extends out, and a corresponding small ejector plate 47 is movably installed inside the top ring 45. The outer diameter of the small ejector plate 47 is smaller than the inner diameter of the top ring 45. When the ejector rod 326 extends out from the second ejector hole 46, it will lift the small ejector plate 47. At this time, the product and the lower mold ejector plate 44 are separated. The second robot arm grabs the product and leaves. The small ejector plate 47 automatically falls back. Then, the movable ends of the lower main cylinder 321 and the secondary ejector cylinder 324 retract respectively. The ejector block 322 and the secondary ejector block 325 return to their original positions. The lower mold ejector plate 44 falls back into the square mold cavity 43. After completing one demolding process, the upper surface of the small ejector plate 47 is flat with the upper surface of the lower mold ejector plate 44. This setting will make the lower end surface of the product flatter.

[0028] In this embodiment, the lower main cylinder 321 and the secondary ejection cylinder 324 are hydraulic cylinders or pneumatic cylinders.

[0029] A weighing sensor is installed on the square mold cavity 43. When the sensor in the square mold cavity 43 detects that the weight of the material has reached the range set by the control system, it will issue an audible reminder and stop feeding.

[0030] Example 3, referring to Figure 1 and Figure 2 The feeding device 8 consists of two sets, including a motor, a support 81, a conveyor belt 82, and a roller assembly. The upper end of the support 81 is equipped with a roller assembly and a conveyor belt 82. The conveyor belt 82 rotates on the roller assembly, which is driven by the motor. The conveyor belt 82 extends into the square mold cavity 43.

[0031] The feeding device 8 is installed on the side of the demolding mechanism 3 for easy material feeding. The roller group is installed on the side plates at both ends of the bracket 81. The roller group includes a drive roller and a driven roller. A sprocket drive is set between the drive roller and the motor. The conveyor belt 82 is in close contact with the drive roller. When the drive roller rotates, it will drive the conveyor belt 82 to rotate as well. With the driven roller, the conveyor belt 82 can rotate easily. When the material is conveyed on it, it will fall into the square mold cavity 43.

[0032] In this embodiment, the powder to be pressed can be pre-loaded into a powder storage box. The powder storage box is electrically connected to the control system. The powder storage box transports the powder to be pressed onto the conveyor belt 82 of the feeding device 8 through a pipeline. When the required powder weight reaches the preset standard, the weighing sensor set on the square mold cavity 43 transmits the signal to the control system. The powder storage box will also close its switch and stop feeding under the control of the control system.

[0033] In Example 4, several first limiting mechanisms and several second limiting mechanisms are symmetrically arranged on both sides of the lower heating plate 23 to restrict the lower mold base plate 41. The first limiting mechanisms limit the mold device 4 in the second demolding mechanism 3b, and the second limiting mechanisms limit the mold device 4 in the first demolding mechanism 6a.

[0034] Reference Figure 8 The first and second limiting mechanisms have the same structure, including a limiting block 24, a spring and a groove. The lower end of the limiting block 24 is connected to the spring, and the lower end of the spring is connected to the groove. When the limiting block is pushed down, it can fall completely into the groove.

[0035] In this embodiment, when the mold device in the first demolding mechanism 3a moves into the hydraulic press, the first limiting mechanism on the lower heating plate, located away from the side of the first demolding mechanism 3a, limits the position of the mold device 4. When the mold device 4a in the first demolding mechanism 3a moves in, the second limiting mechanism, being spring-connected, will tilt into the groove, allowing the mold device 4a to pass through. When the mold device 4a moves out, the second limiting mechanism will pop out of the groove under the action of the spring. Similarly, when the mold device 4b in the second demolding mechanism 3b moves in, the first limiting mechanism will also tilt into the groove, allowing the mold device 4b in the second demolding mechanism 3b to pass through, while the second limiting mechanism limits the position of the mold device 4a in the second demolding mechanism 3b.

[0036] Example 5, as Figure 9 As shown, the feeding device 9 includes a first sliding rod 91, a connecting rod 90, a second sliding rod 92, a vertical rod 93, an inclined rod 94, a push plate 95, and a motor. The first sliding rod 91, the connecting rod 90, and the second sliding rod 92 are connected by a joint shaft. The connecting rod 90 and the second sliding rod 92 can slide on the top of the vertical rod 93. The first sliding rod 91 is fixed to one end of the inclined rod 94, and the other end of the inclined rod 94 is rotatably connected to the vertical rod 93. The push plate 95 is fixedly connected to the end of the second sliding rod 92.

[0037] In use, when the motor rotates the first sliding rod 91, it will pull the connecting rod 90 and the second sliding rod 92 to slide at the top of the upright rod 93. The first sliding rod 91 is fixedly connected to the top of the inclined rod 94, thereby driving the push plate 95 to level the material back and forth in the square mold cavity 43.

[0038] In another embodiment of the material pushing device 9, a lead screw driven by a motor is provided next to the demolding device 3. The lead screw is parallel to the ground, and a push plate is rotatably mounted on the lead screw. The push plate extends into the square mold cavity 43. The motor drives the lead screw to rotate, and the lead screw drives the push plate to move back and forth in the square mold cavity 43, so as to perform material leveling.

[0039] Example 6, refer to Figures 10-12 A control method, comprising the above-described automatic feeding and demolding dual-mold device control system, includes the following steps: First, fix the upper mold onto the upper heating plate, and fix the lower mold onto the lower heating plate 23. Ensure the control system is functioning correctly and is turned on. S1: Mold device 4 enters hydraulic press 2; S2: The heating control system is turned on to preheat the mold device 4; S3: Heating is complete, and mold device 4 returns to its initial position along the original path; S4: The first robotic arm sprays release agent onto mold device 4; S5: The feeding device feeds the mold device 4; S6: The pusher device 9 levels the material in the mold device 4; S7: Mold device 4 enters hydraulic press 2; S8: Press down, the moving crossbeam retracts; S9: Mold device 4 exits via the original route; S10: Demolding; S11: The second robotic arm picks up the finished product and leaves; In S1, the mold device 4 is the first mold device 4a. In S9, after the first mold device 4a exits, the second mold device 4b starts to run, returning to step S1, and repeating S1-S11. Then, after the first mold device 4a performs step S9 in the second mold device 4b, it enters the hydraulic press 2 again and returns to step S1.

[0045] The working principle of this utility model is as follows: (Refer to...) Figure 12 First, install all the equipment and fix the upper mold on the upper heating plate. Ensure that all systems and networks are working properly. Start the system. The first mold device 4a enters the hydraulic press 2 under the drive of the motor 51. The limit block 24 on the right side of the hydraulic press 2 limits the lower mold base plate 41. The information processing module transmits, processes, and outputs the signal. The heating control system controls the upper heating plate and the lower heating plate 23 to preheat the first mold device 4a to a temperature of 150 degrees or higher. After the set temperature is reached, the information processing module transmits, processes, and outputs the signal. Then, the motor control system moves the first mold device 4a out. The first mold device 4a moves to the mold stop 316 on the support frame 31 and stops. The first robot arm senses the first mold device 4a and sprays the release agent. After the spraying is completed, the information processing module transmits, processes and outputs the signal, and the feeding device 8 starts to automatically feed the material. After the feeding reaches the weight set by the control system, the feeding stops. Afterwards, the information processing module transmits, processes, and outputs the signal. The material pushing control system receives the information, and the material pushing device 9 starts pushing the material. After the material is leveled, the signal is transmitted to the motor control system. The motor 51 moves the first mold device 4a into the hydraulic press 2. The hydraulic press 2 receives the signal and starts pressing. The upper mold presses the material in the square mold cavity 43, then holds the pressure and releases the pressure. After pressing is completed, the three main cylinders on the upper crossbeam of the hydraulic press 2 retract. Then, ejector cylinder 22 receives a signal and begins to lift the movable beam, which drives the upper mold to rise, and the upper mold separates from the square mold cavity 43; After receiving the separation information between the upper mold and the square mold cavity 43, the motor control system controls the motor 51 to pull out the first mold device 4a and move it to the mold stop 316 on the support frame 31 to stop. After receiving the demolding signal from the first mold device 4 to demold, the demolding control system controls the movable ends of the two lower main cylinders 321 to extend, driving the entire ejection mechanism 32 to rise. Ejector rod 1 323 and ejector rod 2 326 lift the lower mold ejection plate 44 through the first ejection hole 42 on the lower mold base plate 41. The lower mold ejection plate 44 then lifts the finished product. The product rises to the upper surface of the square mold cavity 43; at this time, the two lower main cylinders 321 remain stationary, and then the two secondary ejector cylinders 324 drive the ejector rod 326 to extend into the second ejector hole 46 in the top ring 45, lifting the small top plate 47, and separating the lower mold ejector plate 44 from the product; after receiving the removal information from the first mold device 4a, the second mold device 4b begins to enter the hydraulic press 2 for the preheating step. Similarly, it can be understood that the product pressing step in the second mold device 4b is the same as the step in the first mold device 4a. The first mold device 4a and the second mold device 4b respectively perform cyclic pressing operations in the hydraulic press 2.

[0046] The steps described above involve the motor control system, heating control system, hydraulic control system, demolding control system, and robot control system receiving, transmitting, processing, and outputting signals through information processing modules. This allows different control systems to operate in an orderly manner, improving the level of automation, reducing labor costs, and increasing work efficiency.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
