The output rod of the material ejector cylinder 54 passes through and slides through the first fixing plate, the lower platform 1 and the mounting plate 2 in sequence. The output rod of the material ejector cylinder 54 drives the connecting block 23 to move upward, so that the first lower mold base 14, the second lower mold base 15 and the third lower mold base 16 move upward to realize the material receiving function.

[0036] An anti-rotation positioning key is provided between the receiving sleeve 24 and the first lower mold base 14, an anti-rotation positioning key is provided between the lower cutting tool fixing sleeve 33 and the second lower mold base 15, and an anti-rotation positioning key is provided between the shaping lower flower top 43 and the third lower mold base 16; at the same time, anti-rotation positioning keys are provided at the contact positions of the first lower mold base 14, the second lower mold base 15 and the third lower mold base 16 with the sliding seat 13.

[0037] In use, the copper shell processing mold is installed inside the four-column press, and various auxiliary functional components are configured according to the processing requirements. The specific processing flow for the copper shell is as follows: the copper shell is fed into the feeding positioning block 11 through the feeding channel 12. The receiving up-and-down movable cylinder 6 drives the feeding gripper cylinder 7 to move downward, so that the feeding gripper 8 can clamp the copper shell. The receiving up-and-down movable cylinder 6 then drives the feeding gripper cylinder 7 to move upward. Then, the receiving transverse cylinder 5 drives the receiving up-and-down movable cylinder 6 and the feeding gripper cylinder 7. The movement causes the copper shell to move directly above the first lower mold base 14. At this time, the ejector cylinder 54 lifts the first lower mold base 14, sending the copper shell into the receiving sleeve 24 in the first station. Then, the loading gripper cylinder 7 controls the loading gripper 8 to release the copper shell, and the output rod of the ejector cylinder 54 retracts to the initial position. The first lower mold base 14 moves downward to the initial position, and then the first cylinder 48 drives the sliding seat 13 to move to the right to the mold processing position for mold closing processing. At this time, the copper shell will pass through the processing of the first station. After processing at the first station, cylinder 48 moves the sliding seat 13 to the left to the loading and receiving position, and the ejector cylinder 54 operates again, allowing the lower mold base 14 to receive another copper shell. Then, the copper shell in the shaping mold base 18 at the first station is unloaded and enters the hook fixing sleeve at the second station. The sliding seat 13 moves to the right again to the mold processing position for mold closing. After hooking the copper shell, the sliding seat 13 moves to the left again to the loading and receiving position, and the ejector cylinder 54 operates again. This allows the No. 1 lower mold base 14 to receive another copper shell. Then, the copper shell in the No. 2 shaping mold base 19 in the second station is unloaded and connected to the shaping lower flower top 43 of the No. 3 lower mold base 16 in the third station. Then, the sliding seat 13 moves to the right again to the mold processing position for mold closing processing. After processing is completed, the sliding seat 13 moves to the left to the feeding and receiving position. The copper shell is unloaded into the discharge port installed on the machine table through the unloading ejector rod 30. The entire processing is completed automatically. Repeating the above actions can realize the automated processing of copper shells.

[0038] When the copper shell processing mold is closed, the hydraulic cylinder of the four-column press drives the upper platen 4 to slide downward along the guide column 3, causing the upper platen 4 to move downward along the upper mold fixing plate 17. The stripper plate 52 will contact the top of the upper platen 4, and at the same time, the stripper plate 52 will also slide along the stripper guide rod 51. At this time, the stripper ejector rod 30 and the stripper plate 52 are separated, and the bottom end of the stripper ejector pin 41 also leaves the top of the splitting hook stripper sleeve 37. When the mold is opened, the hydraulic cylinder of the four-column press drives the upper platen 4 to slide upward along the guide column 3, causing the upper platen 4 to move upward along the upper mold fixing plate 17, so that the bottom of the upper platen 4 separates from the top of the stripper plate 52, realizing the mold opening. The stripper plate 52 abuts against the bottom of the stripper limit block 53. Then the upper platen 4 continues to move upward. Through the action of the stripper ejector pin 41 and the stripper ejector rod 30, the copper shell in the three stations is unloaded.
