[0003] In some existing powder presses, there is a situation where the mold of the molding device needs to be replaced frequently. In such powder presses, when replacing the mold, it is necessary to detach the powder weighing device and the powder feeding device at the feed end of the molding device, and at the same time detach the glove box at the discharge end of the molding device to provide a larger operating space for replacing the mold. The operation is cumbersome and the mold replacement is inconvenient. Summary of the invention

[0004] In order to solve the defect of inconvenience in replacing the mold in the material cart in the prior art, the present invention provides a magnetic field forming press.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: The present invention provides a magnetic field forming press, which comprises a frame, a powder weighing device, a powder feeding device and a forming device, wherein the forming device is arranged on the frame, and the forming device comprises a mold for powder forming; the powder weighing device is used to weigh a certain amount of powder, and the powder feeding device is used to transport the powder weighed by the powder weighing device to the forming device; the powder weighing device is arranged above the powder feeding device, and the powder feeding device can reciprocate above the forming device to sprinkle the powder into the mold; The magnetic field molding press also includes a rear sealed box and a glove box, and the powder weighing device and the powder feeding device are arranged in the rear sealed box; the rear sealed box is rotatably connected to the side of the frame located at the feed end of the molding device, and the glove box is slidably arranged on the side of the frame located at the discharge end of the molding device.

[0006] In this solution, the molding device is arranged on a frame, and the frame is connected to a rear sealing box at the feeding end of the molding device. A powder weighing device and a powder feeding device are arranged in the rear sealing box. The powder weighing device weighs a certain amount of powder and then puts it into the powder feeding device. The powder feeding device transports the powder to the top of the mold of the molding device, and reciprocates above the molding device to evenly sprinkle the powder into the mold, so that there is no need to manually scrape the powder of the mold, which is convenient for users to operate; the frame is connected to a glove box at the discharge end of the molding device, and the user can operate in the glove box to package the molded workpiece. Among them, the rear sealing box is rotatably connected to the side of the frame located at the feeding end of the molding device, and the glove box is slidably arranged on the side of the frame located at the discharge end of the molding device, so that when the mold of the molding device needs to be replaced, it is only necessary to rotate the rear sealing box and slide the glove box, so that the rear sealing box and the glove box can be separated from the frame to expose the molding device, thereby facilitating the replacement of the mold of the molding device. After the mold is replaced, the rear sealing box is rotated in the opposite direction, and the glove box is slid in the opposite direction so that the glove box and the rear sealing box are respectively installed on both sides of the frame, and the operation is simple and convenient.

[0007] Furthermore, the rear sealed box is provided with a first locking mechanism for locking the rear sealed box to the frame, and the glove box is provided with a second locking mechanism for locking the glove box to the frame.

[0008] In this solution, when the rear sealing box is rotated to the closed frame and located on one side of the feeding end of the molding device, the rear sealing box and the frame are locked by the first locking mechanism; when the glove box is moved to the closed frame and located on one side of the discharging end of the molding device, the glove box and the frame are locked by the second locking mechanism. Thus, when the mold does not need to be replaced, the rear sealing box and the glove box are stably connected to the frame, so that the magnetic field molding press can work normally.

[0009] Furthermore, the frame is vertically provided with a rotating shaft at the feeding end of the forming device, and the edge of the rear sealing box is provided with a shaft sleeve that rotates with the rotating shaft.

[0010] In this solution, the frame and the rear sealing box are matched through the rotating shaft and the shaft sleeve, the connection strength between the frame and the rear sealing box is good, and the installation is convenient.

[0011] Furthermore, the magnetic field forming press also includes a walking track, which is arranged on one side of the frame located at the discharge end of the forming device, and the walking track is arranged at the bottom of the glove box; the bottom of the glove box is connected to a walking wheel, and the walking wheel rolls with the walking track.

[0012] In this solution, the glove box realizes the sliding setting of the glove box through the cooperation of the walking rollers and the walking tracks. The structure is simple, the glove box slides smoothly, and the installation is convenient.

[0013] Furthermore, the powder feeding device includes a material cart, a driving electric cylinder and a first supporting rail, the driving electric cylinder is fixed in the rear sealed box, and the driving end of the driving electric cylinder is connected to the material cart; the first supporting rail is arranged in the rear sealed box and extends in a direction close to the molding device, the material cart is slidably matched with the first supporting rail, and the material cart is used to load powder and put the powder into the mold.

[0014] In this solution, the powder feeding device loads powder through a trolley, and the driving electric cylinder drives the trolley to move along the first support track to transport the powder to the mold. When the powder is put into the mold, the driving electric cylinder also facilitates the control of the trolley to reciprocate above the mold to make the powder placement more uniform.

[0015] Furthermore, in some embodiments, the frame is fixedly provided with a second support rail above the mold, and the second support rail is provided corresponding to the first support rail; when the rear sealing box is rotated to close the frame, the second support rail and the first support rail are located on the same straight line.

[0016] In the present solution, the first support rail supports the material cart to move in the rear sealed box. When the rear sealed box rotates to the closing frame (that is, the rear sealed box rotates to the bonding frame), the first support rail and the second support rail correspond and are located on the same straight line, so that the material cart can switch from the first support rail to the second support rail at this time, so as to continue to move above the mold to transport the powder to the mold; thereby, through the segmented arrangement of the first support rail and the second support rail, the first support rail and the second support rail will not affect the normal rotation of the rear sealed box, and at the same time, when powder delivery is required, the first support rail and the second support rail can support the material cart to move to the mold to add powder to the mold.

[0017] Further, in some embodiments, at least one telescopic rail is provided outside the first support rail, the telescopic rail is connected to the rear sealed box, the telescopic rail is arranged parallel to the first support rail, and the first support rail is slidably connected to the telescopic rail.

[0018] In the present scheme, a telescopic rail is slidably provided outside the first support rail, and the first support rail is connected to the rear sealing box through the telescopic rail; when powder is delivered, the driving electric cylinder drives the material cart to move along the first support rail toward the molding device, and the driving electric cylinder can also drive the first support rail to slide relative to the telescopic rail through the material cart to extend into the top of the mold in the frame, so as to deliver powder through the material cart; when the powder delivery is completed, the driving electric cylinder drives the material cart to move along the first support rail toward the molding device, and the driving electric cylinder also drives the first support rail to slide relative to the telescopic rail through the material cart to retract the rear sealing box, thereby facilitating the rotation of the rear sealing box relative to the frame to open the frame.

[0019] Further, the material cart comprises a vehicle body, a powder box, a bottom plate and an opening and closing cylinder, the vehicle body can be moved and matched with the first support track, the powder box is used to load powder, the powder box is arranged in the vehicle body and can move in the vehicle body; the bottom plate is arranged at the bottom of the vehicle body, the bottom of the powder box is provided with a material discharge port, and the material discharge port is attached to the upper side of the bottom plate; A powder outlet is provided on the bottom plate, and the powder outlet is staggered with the feed opening. The cylinder body of the opening and closing cylinder is fixed to the bottom plate, and the driving end of the opening and closing cylinder is connected to the powder box. The opening and closing cylinder can drive the powder box to move to the feed opening and align with the powder outlet.

[0020] In this solution, the feed cart is loaded with powder through the powder box in the body, and the body cooperates with the first support track to drive the bottom plate, the powder box and the opening and closing cylinder to move. When carrying powder, the bottom plate is attached to the discharge port at the bottom of the powder box to close the powder box. When the feed cart moves to the top of the mold, the opening and closing cylinder drives the powder box to move so that the discharge port is aligned with the powder outlet, and the powder in the powder box is sprinkled into the mold. As a result, when carrying powder, the powder in the powder box is not easy to spill onto the first support track, reducing the loss of powder during the powder delivery process, ensuring the powder delivery accuracy, and at the same time ensuring the sanitation of the working environment of the feed cart, and it is not easy to affect the stable operation of the feed cart due to the spilled powder between the first support track and the body. Compared with the solution in which the powder box in the traditional feed cart directly contacts the track to close the discharge port of the powder box through the track, the powder box in this solution does not contact the first support track, reducing the wear between the powder box and the first support track.

[0021] Furthermore, the bottom plate is provided with a guide rail, the guide rail is arranged parallel to the opening and closing cylinder, the powder box is provided with a guide block protruding along the direction toward the guide rail, and the guide block is slidably matched with the guide rail.

[0022] In this solution, the guide rail and the guide block slide together, so that the opening and closing cylinder drives the powder box to move more stably.

[0023] Furthermore, the material cart also includes a lifting cylinder, a cylinder body of the lifting cylinder is fixed to the vehicle body, and a driving end of the lifting cylinder is connected to the base plate to drive the base plate, the opening and closing cylinder and the powder box to rise and fall synchronously.

[0024] In this solution, the lifting cylinder is connected between the base plate and the vehicle body. When the material cart carries powder, the lifting cylinder drives the base plate and the powder box and the opening and closing cylinder on the base plate to rise synchronously, so that the material cart is not easy to interfere with the components in the rear sealing box; when the material cart moves to the top of the mold, the lifting cylinder can drive the base plate, the powder box and the opening and closing cylinder to descend, so that the base plate fits above the mold, so that the powder will not leak out of the mold during the process of being sprinkled into the mold, further ensuring the sanitation of the working environment of the magnetic field forming press, and in the process of the material cart repeatedly moving to sprinkle the powder into the mold, the base plate attached to the top of the mold can level the powder in the mold, reduce manual operation, and improve processing efficiency.

[0025] Furthermore, one end of the vehicle body close to the forming device is connected with a pneumatic clamp and a release agent nozzle, a tension spring is connected between the vehicle body and the bottom plate, and the tension spring is arranged on the side of the opening and closing cylinder facing the powder box.

[0026] In this solution, a pneumatic clamp and a release agent nozzle are provided at one end of the vehicle body close to the molding device. The release agent nozzle sprays the release agent in the mold to facilitate demolding of the product after molding. The pneumatic clamp can clamp the demolded product, so that the molded product can be taken from the mold and placed in the glove box through the material cart. There is no need to set up an additional mechanism for clamping the product, thereby further streamlining the magnetic field molding press.

[0027] Furthermore, a limiting block is arranged on the outer side of the vehicle body, the first supporting rail is arranged on the side of the vehicle body, and the first supporting rail is provided with a sliding groove which is slidably matched with the limiting block.

[0028] In this solution, the first support rail is slidably matched with the limit block on the outside of the vehicle body, and the vehicle body is supported laterally by the first support rail. The setting of the first support rail will not affect the lifting and lowering of the bottom plate.

[0029] In summary, the present invention has the following beneficial effects: In the present invention, the rear sealing box can be rotatably connected to the side of the frame located at the feeding end of the molding device, and the glove box can be slidably arranged on the side of the frame located at the discharging end of the molding device. Therefore, when it is necessary to replace the mold of the molding device, it is only necessary to rotate the rear sealing box and slide the glove box to separate the rear sealing box and the glove box from the frame to expose the molding device, thereby facilitating replacement of the mold of the molding device. After the mold is replaced, the rear sealing box is rotated in the opposite direction, and the glove box is slid in the opposite direction so that the glove box and the rear sealing box are respectively installed on both sides of the frame. The operation is simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] The present invention will be further described below in conjunction with the accompanying drawings.

[0041] Example 1 This embodiment discloses a magnetic field forming press 1000, referring to Figure 1 The magnetic field forming press 1000 includes a frame 100, a powder weighing device 400, a powder feeding device 500 and a forming device 600. The forming device 600 is arranged on the frame 100, and the forming device 600 includes a mold for powder forming. The powder weighing device 400 is used to weigh a certain amount of powder, and the powder feeding device 500 is used to transport the powder weighed by the powder weighing device 400 to the forming device 600.

[0042] The frame 100 is connected with a rear sealing box 200 and a glove box 300. The rear sealing box 200 is rotatably connected to one side of the frame 100 located at the feeding end of the molding device 600, and the glove box 300 is slidably arranged on one side of the frame 100 located at the discharging end of the molding device 600.

[0043] Among them, the powder weighing device 400 and the powder feeding device 500 are arranged in the rear sealed box 200. The powder feeding device 500 can move along the rear sealed box 200 to the mold of the molding device 600, and the powder feeding device 500 reciprocates above the molding device 600 to sprinkle the powder into the mold. The frame 100 is connected to the rear sealed box 200 at the feeding end of the molding device 600, and the powder weighing device 400 and the powder feeding device 500 are arranged in the rear sealed box 200. The powder weighing device 400 weighs a certain amount of powder and then loads it into the powder feeding device 500. The powder feeding device 500 transports the powder to the mold above the molding device 600, and reciprocates above the molding device 600 to evenly sprinkle the powder into the mold, so that there is no need to manually scrape the powder on the mold, which is convenient for users to operate.

[0044] The glove box 300 is used for users to operate and package the molded workpiece. In this embodiment, since the rear sealed box 200 is rotatably connected to the side of the frame 100 located at the feeding end of the molding device 600, the glove box 300 is slidably arranged on the side of the frame 100 located at the discharging end of the molding device 600, so that when the mold of the molding device 600 needs to be replaced, it is only necessary to rotate the rear sealed box 200 and slide the glove box 300 to separate the rear sealed box 200 and the glove box 300 from the frame 100 to expose the molding device 600, thereby facilitating the replacement of the mold of the molding device 600. After the mold is replaced, the rear sealed box 200 is rotated in the opposite direction, and the glove box 300 is slid in the opposite direction so that the glove box 300 and the rear sealed box 200 are respectively installed on both sides of the frame 100, and the operation is simple and convenient.

[0045] Specifically, refer to Figures 1 to 3In this embodiment, a rotating shaft 110 is vertically arranged on the outside of the frame 100 on one side of the feeding end of the molding device 600, and a shaft sleeve 210 is arranged on the edge of the rear sealing box 200. A through hole that rotatably cooperates with the rotating shaft 110 is opened on the shaft sleeve 210. The frame 100 and the rear sealing box 200 cooperate with the rotating shaft 110 and the shaft sleeve 210 to realize the rotational connection between the rear sealing box 200 and the frame 100. The rear sealing box 200 can rotate relative to the frame 100 around the rotating shaft 110 to open or close the side of the frame 100 located at the feeding end of the molding device 600. The connection strength between the frame 100 and the rear sealing box 200 is good and the installation is convenient.

[0046] Among them, a first locking mechanism 220 for locking the rear sealing box 200 to the frame 100 is provided on the rear sealing box 200. When the rear sealing box 200 and the frame 100 are rotated to close and are located on one side of the feeding end of the molding device 600, the rear sealing box 200 and the frame 100 are locked by the first locking mechanism 220. Therefore, when the mold does not need to be replaced, the rear sealing box 200 is stably connected to the frame 100, so that the magnetic field molding press 1000 can work normally.

[0047] A running track 700 is provided at the bottom of the glove box 300. The running track 700 is provided on one side of the frame 100 at the discharge end of the molding device 600. Specifically, in the present embodiment, the running track 700 and the frame 100 are both fixed on the ground. A plurality of running wheels 310 are connected to the bottom of the glove box 300. The running wheels 310 are rollingly matched with the running track 700 and guided by the running track 700. The glove box 300 realizes the sliding setting of the glove box 300 through the cooperation of the running rollers and the running track 700. The structure is simple, the glove box 300 slides smoothly, and the installation is convenient.

[0048] The glove box 300 is provided with a second locking mechanism 320 for locking the glove box 300 to the frame 100. When the glove box 300 moves to the side where the frame 100 is located at the discharge end of the molding device 600, the second locking mechanism 320 locks the glove box 300 with the frame 100. Thus, when the mold does not need to be replaced, the glove box 300 is stably connected to the frame 100, so that the magnetic field molding press 1000 can work normally.

[0049] In this embodiment, the first locking mechanism 220 and the second locking mechanism 320 are both lock buckles, so as to quickly and labor-savingly lock the frame 100 with the rear sealed box 200 and the frame 100 with the glove box 300. In addition, in other embodiments, the locking mechanism can also be a detachable connector such as a bolt or a buckle.

[0050] Reference Figure 1 and Figure 2In this embodiment, the powder weighing device 400 is arranged above the powder feeding device 500 so that the weighed powder can be driven into the powder feeding device 500 by gravity. The structure of the powder weighing device 400 is the same as that in the prior art, and includes a lower powder pipe, a powder hopper, a powder vibrator and a powder weighing box. The powder enters the powder weighing box through the lower powder pipe and the powder hopper under the vibration of the powder vibrator. After the powder weighing box weighs a certain amount of powder, the powder weighing box is driven to flip by a cylinder connected to the powder weighing box to pour the weighed powder into the powder feeding device 500.

[0051] Reference Figures 1 to 6 The powder feeding device 500 includes a trolley 510, a driving electric cylinder 520 and a first support rail 530. The driving electric cylinder 520 is fixed in the rear sealed box 200, and the driving end of the driving electric cylinder 520 is connected to the trolley 510. The first support rail 530 is arranged in the rear sealed box 200 and extends in the direction close to the molding device 600. The trolley 510 slides and fits on the first support rail 530. The trolley 510 is used to load powder and put the powder into the mold. The driving electric cylinder 520 drives the trolley 510 to move along the first support rail 530 to transport the powder to the mold. When putting the powder into the mold, the driving electric cylinder 520 also facilitates the control of the trolley 510 to reciprocate above the mold to make the powder delivery more uniform.

[0052] Reference Figure 6 and Figure 7 The material cart 510 includes a car body 511, a powder box 512, a bottom plate 513 and an opening and closing cylinder 514. The car body 511 is movable and matched with the first support rail 530. The powder box 512 has an inner cavity for loading powder. The powder box 512 is arranged in the car body 511 and can move in the car body 511. The bottom plate 513 is arranged at the bottom of the car body 511. The cylinder body of the opening and closing cylinder 514 is fixed to the bottom plate 513, and the driving end of the opening and closing cylinder 514 is connected to the powder box 512. The powder box 512 can be driven to move relative to the bottom plate 513 through the opening and closing cylinder 514.

[0053] Reference Figures 6 to 8 , wherein the upper sides of the powder box 512 and the vehicle body 511 are both open, so that the powder weighing device 400 can pour the weighed powder into the powder box 512. The bottom of the powder box 512 is provided with a discharge port 5121 connected to its inner cavity, and the discharge port 5121 is attached to the upper side of the bottom plate 513. The bottom plate 513 is provided with a powder outlet 5133, and the powder outlet 5133 is staggered with the discharge port 5121. The opening and closing cylinder 514 can drive the powder box 512 to move to the discharge port 5121 to align with the powder outlet 5133.

[0054] When carrying powder, the bottom plate 513 is attached to the discharge port 5121 at the bottom of the powder box 512 to close the powder box 512. When the feed cart 510 moves to the top of the mold, the opening and closing cylinder 514 drives the powder box 512 to move so that the discharge port 5121 is aligned with the powder outlet 5133, and the powder in the powder box 512 is sprinkled into the mold. Therefore, when carrying powder, the powder in the powder box 512 is not easy to spill onto the first support rail 530, ensuring the sanitary condition of the working environment of the feed cart 510, and the stable operation of the feed cart 510 is not easily affected by the spilled powder between the first support rail 530 and the car body 511. At the same time, compared with the solution in which the powder box 512 in the traditional feed cart 510 directly contacts the track to close the discharge port 5121 of the powder box 512 through the track, in this solution, the powder box 512 does not contact the first support rail 530, reducing the wear between the powder box 512 and the first support rail 530.

[0055] In this embodiment, the first support rail 530 is provided with one on each side of the vehicle body 511, and the vehicle body 511 is provided with a limit block 5111 on both sides thereof. The first support rail 530 is provided with a slide groove 800 that can slidably cooperate with the limit block 5111. The first support rail 530 slidably cooperates with the limit block 5111 on the outside of the vehicle body 511, and the vehicle body 511 is supported laterally by the first support rail 530. The provision of the first support rail 530 will not affect the lifting and lowering of the bottom plate 513.

[0056] Reference Figure 5 and Figure 6 The frame 100 is fixedly provided with a second support rail 120 above the mold, and two second support rails 120 are provided in parallel, and the two second support rails 120 are provided one-to-one with the two first support rails 530. When the rear sealing box 200 rotates to close the frame 100, the second support rail 120 and the first support rail 530 are provided along the same straight line, and the material cart 510 can move from the first support rail 530 to the second support rail 120, so that the material cart 510 can walk above the mold to add powder into the mold.

[0057] Therefore, through the segmented setting of the first support rail 530 and the second support rail 120, the first support rail 530 and the second support rail 120 will not affect the normal rotation of the rear sealing box 200 relative to the frame 100. At the same time, when powder delivery is required, the first support rail 530 and the second support rail 120 can support the material cart 510 to move to the mold to add powder to the mold.

[0058] The second support rail 120 is also provided with a slide groove 800 that cooperates with the limit block 5111, so as to realize the sliding cooperation between the trolley 510 and the second support rail 120. The slide groove 800 on the second support rail 120 is flared in an eight-shaped shape toward one end of the first support rail 530, and the slide groove 800 on the first support rail 530 is flared in an eight-shaped shape toward one end of the second support rail 120, so as to realize the transfer of the trolley 510 between the first support rail 530 and the second support rail 120.

[0059] Reference Figure 7 The bottom plate 513 includes a lower friction plate 5131 and an upper friction plate 5132. The lower friction plate 5131 is arranged parallel to the lower side of the upper friction plate 5132. The powder box 512 is arranged on the upper side of the upper friction plate 5132. The powder outlet 5133 penetrates the lower friction plate 5131 and the upper friction plate 5132 at the same time. In this embodiment, the lower friction plate 5131 and the upper friction plate 5132 are made of different materials. Specifically, the lower friction plate 5131 is made of polytetrafluoroethylene, and the upper friction plate 5132 is made of stainless steel, thereby improving the wear resistance of the bottom plate 513 while meeting the structural strength of the bottom plate 513.

[0060] Reference Figure 8 A guide rail 515 is provided on the upper side of the bottom plate 513, and the guide rail 515 is provided parallel to the opening and closing cylinder 514. A guide block 5122 is protruded on the side of the powder box 512 in the direction toward the guide rail 515. The guide block 5122 can be slidably engaged with the guide rail 515, thereby making it more stable when the opening and closing cylinder 514 drives the powder box 512 to move along the bottom plate 513.

[0061] Reference Figure 7 and Figure 8 In this embodiment, the material cart 510 further includes a lifting cylinder 518, which is vertically arranged, and the cylinder body of the lifting cylinder 518 is fixed to the vehicle body 511, and the driving end (i.e., piston rod) of the lifting cylinder 518 is connected to the bottom plate 513. Since the cylinder body of the opening and closing cylinder 514 is fixed to the bottom plate 513, and the powder box 512 is matched with the guide rail 515 on the bottom plate 513 through the guide block 5122, the lifting cylinder 518 can drive the bottom plate 513, the opening and closing cylinder 514 and the powder box 512 to rise and fall synchronously.

[0062] When the trolley 510 carries powder, the lifting cylinder 518 drives the bottom plate 513 and the powder box 512 and the opening and closing cylinder 514 on the bottom plate 513 to rise, so that the trolley 510 is not easy to interfere with the components in the rear sealing box 200, reducing the wear of the bottom plate 513. When the trolley 510 moves to the top of the mold, the lifting cylinder 518 can drive the bottom plate 513, the powder box 512, and the opening and closing cylinder 514 to descend, so that the bottom plate 513 fits on the top of the mold, so that the powder will not leak out of the mold during the process of sprinkling into the mold, further ensuring the sanitation of the working environment of the magnetic field forming press 1000. In addition, in the process of the trolley 510 repeatedly moving to sprinkle the powder into the mold, the bottom plate 513 affixed to the top of the mold can flatten the upper side of the powder in the mold, reducing manual operations and improving processing efficiency.

[0063] In this embodiment, a lifting cylinder 518 is provided at each of the four corners of the vehicle body 511, and the base plate 513 is synchronously driven to rise and fall by the four lifting cylinders 518, so that the base plate 513 is more stable when rising and falling. In addition, in other embodiments, the number of the lifting cylinders 518 can also be one or other suitable numbers.

[0064] One end of the vehicle body 511 close to the molding device 600 is connected to a pneumatic clamp 516 and a mold release agent nozzle 517. The mold release agent nozzle 517 sprays the mold release agent in the mold to facilitate demolding of the product after molding. The pneumatic clamp 516 can clamp the demolded product, so that the molded product can be taken from the mold and placed in the glove box 300 through the material cart 510. There is no need to set up an additional mechanism for clamping the product, thereby further streamlining the magnetic field molding press 1000.

[0065] A tension spring 519 is connected between the vehicle body 511 and the base plate 513. The tension spring 519 is arranged on the side of the opening and closing cylinder 514 facing the powder box 512. The tension spring 519 provides a pulling force toward the vehicle body 511 for the base plate 513 to balance the force on the base plate 513. The base plate 513 is not prone to being heavier on the side close to the molding device 600 because the cylinder body of the opening and closing cylinder 514 is arranged on the side close to the molding device 600, thereby causing the base plate 513 to tilt relative to the lifting cylinder 518 and affecting the lifting of the lifting cylinder 518.

[0066] Example 2 A magnetic field forming press in this embodiment is substantially the same as that in embodiment 1, except that: In this embodiment, the frame 100 is not provided with the second support rail 120 above the mold of the molding device 600 .

[0067] Reference Fig. 9In this embodiment, the first support rail 530 is movably disposed in the rear sealed box 200. Specifically, at least one telescopic rail 900 is disposed outside the first support rail 530, and the telescopic rail 900 is connected to the inner wall of the rear sealed box 200. In this embodiment, the telescopic rail 900 is disposed parallel to the outside of the first support rail 530, and the first support rail 530 is slidably matched with the telescopic rail 900.

[0068] Thus, the first support rail 530 can be telescopically arranged on the rear sealing box 200 through the telescopic rail 900. When feeding powder, the driving electric cylinder 520 drives the trolley 510 to move along the first support rail 530 in the direction close to the molding device 600. The driving electric cylinder 520 can also drive the first support rail 530 to slide relative to the telescopic rail 900 through the trolley 510 to extend above the mold in the frame 100, so that the trolley 510 can move above the mold to deliver powder. When the powder delivery is completed, the driving electric cylinder 520 drives the trolley 510 to move along the first support rail 530 in the direction away from the molding device 600. The driving electric cylinder 520 also drives the first support rail 530 to slide relative to the telescopic rail 900 through the trolley 510 to retract the rear sealing box 200, so as to facilitate the rotation of the rear sealing box 200 relative to the frame 100 to open the frame 100.

[0069] Among them, at least one telescopic rail 900 is arranged outside the first support rail 530. Specifically, in this embodiment, two telescopic rails 900 are arranged outside the first support rail 530, and the two telescopic rails 900 are sequentially stacked on the outside of the first support rail 530. Among them, the outermost telescopic rail 900 is fixedly connected to the inner wall of the rear sealed box 200, and the other telescopic rail 900 is slidably arranged between the outermost telescopic rail 900 and the inner first support rail 530. Therefore, when feeding, in addition to the first support rail 530 being able to slide and retract relative to the telescopic rail 900, a telescopic rail 900 directly connected to the first support rail 530 can also be retracted relative to the outermost telescopic rail 900, thereby further reducing the length of the first support rail 530 while satisfying the travel of the material cart 510, and further reducing the length of the rear sealed box 200.

[0070] In addition, in other embodiments, the telescopic rails 900 may also be set to other suitable numbers. The specific setting method is that the outermost telescopic rail 900 is fixed to the rear sealed box 200, and the other telescopic rails 900 are stacked in sequence between the first support rail 530 and the outermost telescopic rail 900, and the telescopic rails 900 and the telescopic rails 900 and the first support rail 530 can be slidably matched.

[0071] The above description is only a preferred embodiment of the present invention, so all equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
