Description

Technical Field

[0001] The invention relates to the technical field of automobile parts processing, in particular to a die-casting molding device for an automobile generator end cover. Background Art

[0002] The end cover of the automobile generator is an important part of the automobile generator (or alternator). It is usually located at one of the two ends of the generator and plays a role in protecting and supporting the key components inside the generator. The end cover not only supports the structure of the generator, but also involves multiple functions such as electrical connection, heat dissipation, and lubrication.

[0003] Die casting of automobile generator end covers is a production method. This method uses a casting process to inject liquid metal into a mold, and then cools and solidifies to obtain end cover parts. Die casting is usually used to produce automobile generator end covers made of aluminum alloy or other light metal materials. It is widely used in the automotive manufacturing field because of its high precision, low production cost and good mechanical properties.

[0004] During the die-casting process of the automobile generator end cover, a gate bulge will be formed at the gate position. Since the existing technology is not convenient for automatically removing the gate during the die-casting of the automobile generator end cover, this may cause irregular shapes on the surface of the end cover, thereby affecting the subsequent processing of the end cover, especially for parts with high precision requirements (such as docking surfaces or mounting holes, etc.), increasing the complexity of subsequent processes.

[0023] like Figure 6As shown, the pushing mechanism 6 includes two connecting rod groups 601, and the two ends of the connecting rod group 601 are rotatably connected to the fixed seat 5 and the movable seat 7 respectively. One end of the connecting rod group 601 connected to the fixed seat 5 is connected and fixedly provided with a gear 602. The two gears 602 are meshed with each other for transmission.

After the fluid metal is cooled and formed, the hydraulic cylinder 401 is used to drive the upper die base 4 to move upward to separate the molds; When the upper die seat 4 moves upward, the ratchet 404 on the ratchet frame 403 drives the ratchet 605 to rotate, so that the ratchet 605 can drive the connected incomplete bevel gear 604 to rotate. At this time, the incomplete bevel gear 604 will first mesh with one of the bevel gears 603, thereby driving the gear 602 connected to the bevel gear 603 to rotate, so that the gear 602 drives the meshing gear 602 to rotate, thereby driving the two connecting rod groups 601, so that the connecting rod group 601 pushes the moving seat 7 to approach the generator end cover 3; Then, under the action of the guide groove 501, the slider 802 connected to the guide rod 803 moves, so that the slider 802 drives the gate cutter 8 connected to the L-shaped enclosure 801 to move, so that the two gate cutters 8 cut off the gate part on the generator end cover 3; Then, when the moving seat 7 continues to move, the transmission wheel 902 will mesh with the rack 504. At this time, the transmission wheel 902 will drive the threaded rod 903 connected to the universal joint 901 to rotate, so that the threaded rod 903 drives the moving plate 904 to move, and the moving plate 904 drives the pushing plate 905 to move, thereby pushing the cut gate part into the moving seat 7, and falling into the collecting trough 502 through the guide tube 702 for collection. The connected baffle 503 is pulled open by the pull ring 505, so that the collected gate part can be taken out for recycling.
