Technical Field

[0001] This utility model relates to the field of press technology, specifically to an electro-hydraulic servo powder molding press structure that facilitates rapid mold changing. Background Technology

[0002] A powder forming press is a mechanical device used to press powdered materials into products with specific shapes and sizes.

[0003] Announcement No.: CN216993198U includes a press body and a pressure plate. A bidirectional threaded rod is rotatably connected to the lower end of the press body. A transmission block is helically connected to the inner side of the bidirectional threaded rod. A transmission rod is rotatably connected to the upper end of the transmission block. A lifting plate is rotatably connected to the upper end of the transmission rod. The lifting plate is slidably connected to the press body. A lower die is slidably connected to the upper end of the lifting plate. The lower die is slidably connected to the press body. The pressure plate is slidably connected to the upper side of the press body. In this invention, by using the bidirectional threaded rod, transmission rod, and lifting plate, the rotation of the bidirectional threaded rod causes the transmission block to drive the transmission rod to rotate, thereby enabling the lifting plate to lift the lower die. This allows for quick assembly and disassembly of the die through the lifting of the lifting plate, improving the mold-changing efficiency of the press.

[0004] The aforementioned patent has some shortcomings: after pressing, since the workpiece is inside the lower mold and there is no material handling function, the staff needs to take the workpiece out of the lower mold and put it into the collection box to complete the unloading. The manual unloading method is not convenient enough and the workload of the staff is large.

[0005] Therefore, this utility model designs an electro-hydraulic servo powder molding press structure that facilitates rapid mold change in order to solve the problems existing in the prior art. Utility Model Content

[0006] The purpose of this invention is to provide an electro-hydraulic servo powder molding press structure that facilitates rapid mold changing, in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an electro-hydraulic servo powder molding press structure for easy and rapid mold changing, comprising: a base, a top plate on the top of the base, the base and the top plate being fixedly connected at their four corners by support columns, a hydraulic cylinder mounted on the top of the top plate, the output end of the hydraulic cylinder being connected to a mounting plate slidably connected to the support columns, an upper mold at the bottom of the mounting plate, a lower mold at the top of the base, brackets mounted on the bottom of the mounting plate around the upper mold and on the top of the base around the lower mold, fixing components mounted on the brackets, and a material handling component on one side of the base.

[0008] Preferably, the fixing component includes an electric push rod, which is mounted on a bracket. The output end of the electric push rod is equipped with a pin. Slots for insertion into the pin are provided around the lower and upper molds. The electric push rod drives the pin to insert into the slot, which can fix the lower and upper molds to the machine base and the mounting plate respectively. When replacement is required, the electric push rod drives the pin to leave the slot, which can quickly release the fixing of the upper and lower molds.

[0009] Preferably, the bottom of the mounting plate and the top of the base are respectively provided with limiting grooves for insertion into the upper mold and the lower mold. The limiting grooves can position the upper mold and the lower mold, and facilitate the alignment of the slots and pins.

[0010] Preferably, the material handling assembly includes an L-shaped plate, which is installed on one side of the machine base. A U-shaped frame is rotatably installed on the upper side of the L-shaped plate. Both ends of the U-shaped frame are rotatably mounted with lead screws. The outer walls of the two lead screws are slidably installed with the two ends of the L-shaped slide block via threads. An electric cylinder is fixedly installed on one side of the top of the L-shaped slide block. The output end of the electric cylinder is connected to a vacuum suction cup. After pressing, the lead screws rotate to move the L-shaped slide block, which in turn moves the vacuum suction cup to above the lower mold. The electric cylinder drives the vacuum suction cup to descend and pick up the workpiece. Then, the electric cylinder drives the vacuum suction cup to rise and remove the workpiece from the lower mold, thus completing the material handling.

[0011] Preferably, a rotating shaft is rotatably mounted on one side of the L-shaped plate. One side of the rotating shaft is connected to the output end of the drive motor, and the other side of the rotating shaft is fixedly mounted in the middle of one side of the U-shaped frame. The drive motor drives the rotating shaft to rotate, which can make the U-shaped frame rotate and tilt the workpiece, making it easier for the staff to check the bottom of the workpiece.

[0012] Preferably, a collection cylinder is placed on the bottom inner wall of the L-shaped plate, which facilitates the collection of the pressed and shaped workpieces.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention, through the setting of the material handling component, after the pressing is completed, the screw rotates to move the L-shaped slide, which drives the vacuum suction cup to move above the lower mold. The electric cylinder drives the vacuum suction cup to descend and pick up the workpiece. Then, the electric cylinder drives the vacuum suction cup to rise and make the workpiece leave the lower mold to complete the material handling. Then, the screw rotates in the opposite direction to move the workpiece to the top of the collecting cylinder. The electric cylinder drives the vacuum suction cup to descend again, so that the workpiece can enter the collecting cylinder to complete the unloading. Before unloading, the drive motor drives the rotating shaft to rotate, which can tilt the workpiece, making it convenient for the staff to check the bottom of the workpiece. This makes it convenient for the staff to remove the workpiece with defects such as cracks, missing material, or delamination at the bottom for rework. Attached Figure Description

[0018] Please see Figure 1-3 In this embodiment: the fixing component 9 includes an electric push rod 901, which is mounted on the bracket 8. The output end of the electric push rod 901 is equipped with a pin 902. The lower mold 7 and the upper mold 6 are provided with slots 903 around their perimeter for insertion into the pin 902.

[0019] Please see Figure 1-3 In this embodiment: the bottom of the mounting plate 5 and the top of the base 1 are respectively provided with limiting grooves for insertion into the upper mold 6 and the lower mold 7.

[0020] Please see Figure 1-3In this embodiment: the material handling assembly 10 includes an L-shaped plate 101, which is installed on the lower side of one side of the base 1. A U-shaped frame 102 is rotatably installed on the upper side of one side of the L-shaped plate 101. Both ends of the U-shaped frame 102 are rotatably installed with lead screws 103. The outer walls of the two lead screws 103 are slidably installed with the two ends of the L-shaped slide block 104 through threads. An electric cylinder 105 is fixedly installed on the top side of the L-shaped slide block 104. The output end of the electric cylinder 105 is connected to a vacuum suction cup 106. One side of the lead screw 103 is connected to the output end of a servo motor. The two servo motors are controlled by a controller and can rotate synchronously.

[0021] Please see Figure 1-3 In this embodiment: a rotating shaft 107 is rotatably mounted on one side of the L-shaped plate 101. One side of the rotating shaft 107 is connected to the output end of the drive motor 108, and the other side of the rotating shaft 107 is fixedly mounted at the middle of one side of the U-shaped frame 102.

[0022] Please see Figure 1-3 In this embodiment: a collection cylinder 109 is placed on the bottom inner wall of the L-shaped plate 101. A placement groove is opened on the bottom inner wall of the L-shaped plate 101, and the collection cylinder 109 is inserted into the placement groove to improve stability.

[0023] Working principle: The electric push rod 901 drives the pin 902 to insert into the slot 903, fixing the lower mold 7 and upper mold 6 to the machine base 1 and mounting plate 5 respectively. When replacement is needed, the electric push rod 901 drives the pin 902 out of the slot 903, quickly releasing the upper mold 6 and lower mold 7. In use, powder is placed in the lower mold 7, and the hydraulic cylinder 4 lowers the mounting plate 5, causing the upper mold 6 to descend and extrude the powder in the lower mold 7. After molding, the hydraulic cylinder 4 raises the mounting plate 5, causing the upper mold 6 to rise. Then, the lead screw 103 rotates, moving the L-shaped slide 104, which in turn moves the vacuum suction cup 106 above the lower mold 7. The electric cylinder 105 then moves the vacuum suction cup 106. 6. Once the lower die 105 descends and contacts the workpiece, it will be attracted and held. The electric cylinder 105 then drives the vacuum suction cup 106 to rise, allowing the workpiece to leave the lower die 7. Finally, the lead screw 103 rotates in the opposite direction, moving the vacuum suction cup 106 directly above the collecting cylinder 109. The electric cylinder 105 then drives the vacuum suction cup 106 to descend again, allowing the workpiece to fall into the collecting cylinder 109 to complete the unloading. Before unloading, the drive motor 108 drives the rotating shaft 107 to rotate, tilting the workpiece to facilitate the worker's inspection of the bottom of the workpiece. This allows for the identification of defects such as cracks, missing material, and delamination at the bottom of the workpiece, so that defective products can be removed. The contents not described in detail in this instruction are existing technologies known to those skilled in the art.
