Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum die casting processing technology, and in particular to a single punch press for aluminum die casting. Background Technology
[0002] Aluminum die casting punch press is a device used to stamp and form aluminum die castings. Existing aluminum die casting punch presses have a simple structure, and their loading and unloading are mainly completed manually, resulting in low efficiency in batch processing of profiles.
[0003] The technical solution disclosed in Chinese Patent No. CN216828233U involves placing an aluminum die-casting part on a stamping die of an ejector device, activating a drive device, which in turn moves a lifting rod, causing a mounting block to move up and down. This movement of the mounting block allows the upper and lower stamping dies to work together to stamp the aluminum die-casting part. After stamping, the first hydraulic cylinder in the auxiliary material handling device is activated. The output end of the first hydraulic cylinder drives the extension and retraction of a push plate, simultaneously activating the ejector device. The ejector device ejects the stamped casting part, and the casting part is pushed out through the coordinated action of the ejector device and the auxiliary material handling device.
[0004] However, the device still has shortcomings: because the push plate goes straight up and down, for finished aluminum castings with complex bottom structures, simply pushing the push plate upward and pushing it out at an angle by the ejector device is not enough to effectively push the casting out, and the device lacks an active feeding structure. Utility Model Content
[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a single-piece punching press for aluminum die castings.
[0006] The technical solution of this utility model is as follows: A single punch press for aluminum die casting includes a frame, a support platform is centrally located on the frame, and a conveying component A and a conveying component B are respectively arranged on both sides of the support platform on the frame.
[0007] The lower mold base rests on the support platform and is rotatably connected to the frame. A pusher assembly is installed at the bottom of the mold cavity of the lower mold base.
[0008] The drive assembly is connected to the frame and drives the lower die holder to rotate so that the lower die holder is above the conveyor assembly B.
[0009] The feeding assembly is connected to the frame. When in operation, the feeding assembly guides the raw materials conveyed by the conveying assembly A to the feeding station onto the stamping station of the lower die base.
[0010] And a stamping mechanism, which is connected to the frame, and works with the lower die to stamp the raw material into shape.
[0011] Preferably, the frame is provided with a groove, and the support platform, conveying component A, conveying component B and lower mold base are all located in the groove.
[0012] Preferably, the conveying assembly A includes a motor A, a drive roller A, two drive rollers B, and two conveyor belts A. The drive roller A is located within the groove and is rotatably connected to the side plates on both sides of the groove. The motor A is connected to the frame and drives the drive roller A to rotate. The drive rollers B are located within the groove, and the two drive rollers B are rotatably connected to the side plates on the corresponding sides of the groove. The drive rollers A and B are parallel. The two conveyor belts A respectively drive and connect the drive roller A and one of the drive rollers B on one side, so as to form a passageway between the two drive rollers B and the two conveyor belts A.
[0013] Preferably, the feeding assembly includes a guide plate and a hydraulic cylinder B. The guide plate is located in the passageway, and its upper surface is inclined towards the upper surface of the support platform along the feed end of the conveyor belt A. The hydraulic cylinder B is connected to the frame and drives the guide plate to rise and fall, and the upper surface of the guide plate is smooth.
[0014] Preferably, the conveying assembly B includes a motor B, a drive roller C, and a conveyor belt B. Both drive rollers C are located in the groove and are rotatably connected to the side plates on both sides of the groove. The two drive rollers C are connected by the conveyor belt B. The two drive rollers C are parallel to each other. The motor B is connected to the frame and drives one of the drive rollers C to rotate.
[0015] Preferably, the drive assembly includes a rotating shaft and a motor C. The rotating shaft is rotatably connected to the frame and is connected to the end of the lower mold base near the conveying assembly B. The motor C is connected to the frame and drives the rotating shaft and the lower mold base to rotate.
[0016] Preferably, the ejector assembly includes an ejector plate. A receiving groove communicating with the bottom of the mold cavity is provided therein, the ejector plate is located in the receiving groove and is slidably connected to its inner wall, and a hydraulic cylinder A for driving the ejector plate to rise and fall is provided at the bottom of the lower mold base.
[0017] Preferably, the stamping mechanism includes a bracket and an upper die base. The bracket is connected to the machine frame and slidably connected to a mounting plate. The upper die base is connected to the bottom of the mounting plate and is located directly above the lower die base. A hydraulic cylinder C is mounted on the bracket to drive the mounting plate and the upper die base to rise and fall.
[0018] Compared with the prior art, the present invention has the following beneficial technical effects:
[0019] By setting a flip-up lower mold base, after the aluminum casting is formed in the mold cavity of the lower mold base, the lower mold base is flipped so that its opening falls above the conveying component B. Then, the hydraulic cylinder A pushes the push plate to push the formed part down onto the conveying component B. This structure provides stable material output and high efficiency for profiles with complex bottom structures. By setting a feeding component consisting of a guide plate and hydraulic cylinder B, the guide plate rises and uses its inclined upper surface to guide the aluminum casting onto the lower mold base, thereby realizing automatic feeding.

The conveying assembly B includes a motor B, drive rollers C, and conveyor belts B. The two drive rollers C are both located within the groove 101 and are rotatably connected to the side plates on both sides of the groove 101. The two drive rollers C are connected by the conveyor belts B and are parallel to each other. The motor B is connected to the frame 1 and drives one of the drive rollers C to rotate. The lower mold base 5 rests on the support platform 2 and is rotatably connected to the frame 1. A pusher assembly is provided at the bottom of the mold cavity 501 of the lower mold base 5. The pusher assembly includes a pusher plate 8. A receiving groove is provided at the bottom of the mold cavity 501 and communicates with it. The pusher plate 8 is located in the receiving groove and is slidably connected to its inner wall. A hydraulic cylinder A9 is provided at the bottom of the lower mold base 5 to drive the pusher plate 8 to rise and fall. The drive assembly 6 includes a rotating shaft and a motor C. The rotating shaft is rotatably connected to the frame 1 and is also connected to the end of the lower die holder 5 near the conveying assembly B4. The motor C is connected to the frame 1 and drives the rotating shaft and the lower die holder 5 to rotate so that the lower die holder 5 is positioned above the conveying assembly B4. The feeding assembly is connected to the frame 1 and includes a guide plate 10 and a hydraulic cylinder B11. The guide plate 10 is located in the passageway, and its upper surface is inclined along the feed end of the conveyor belt A towards the upper surface of the support platform 2. The hydraulic cylinder B11 is connected to the frame 1 and drives the guide plate 10 to rise and fall. The upper surface of the guide plate 10 is smooth, and the hydraulic cylinder B11 is located in the through hole 201 and does not contact its inner wall.
