Description

Technical Field

[0001] This utility model relates to a pressure gate device for cast aluminum rotor. Background Technology

[0002] The existing cast aluminum rotors have inconsistent gate residues after processing due to the gate breaking during demolding. It is necessary to remove the residual gates on the cast aluminum rotors. Currently, the removal of these residual gates is done manually by workers. However, due to the material of the gates, there is a risk of cuts. Therefore, workers need to be careful when operating, which takes a long time and the consistency is not very good. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to provide a cast aluminum rotor pressure gate device that is easy to operate and has good consistency.

[0004] The technical solution for realizing this utility model is as follows:

[0005] A die-casting rotor gate device includes a base, guide components on both sides of the base, a lower mold assembly on the base, and an upper mold assembly that works in conjunction with the lower mold assembly. The lower mold assembly includes a lower mold gate pressing block mounted on the base and a lower mold pressure plate that can float up and down. The top surface of the lower mold pressure plate has a plurality of slots evenly distributed for the protrusions of the die-casting rotor to be inserted. A guide rod assembly and a guide pin assembly that abuts against the die-casting rotor are provided between the lower mold gate pressing block and the lower mold pressure plate. The guide pin assembly includes a plurality of guide pins evenly distributed with the center of the lower mold gate pressing block as the center. One end of each guide pin abuts against an auxiliary block inside the lower mold gate pressing block, and the other end passes through a through hole in the lower mold pressure plate and abuts against the die-casting rotor.

[0006] The upper mold assembly includes an upper mold frame assembled with a hydraulic press, and an upper mold fixing block below the upper mold frame; the upper mold fixing block is connected in sequence to an upper mold pressure plate fixing block and an upper mold pressure plate via pressure rods.

[0007] The guide rod assembly includes several lower mold unloading screws evenly distributed with the center of the lower mold gate pressure block as the center. One end of the lower mold unloading screw is inserted into the corresponding mounting hole of the lower mold pressure plate, and the other end is inserted into the mounting groove of the lower mold gate pressure block.

[0008] The lower mold unloading screw inside the mounting slot is fitted with a butterfly spring.

[0009] The guiding assembly includes a guide post and a sliding guide seat; the guide post passes through the upper mold frame and is inserted into the mounting hole of the base, and a sliding guide seat is provided below the upper mold frame to cooperate with the guide post.

[0010] Using the above technical solution, this device is driven by a hydraulic press. Under the drive of the hydraulic press, the upper mold frame and fixing block press down on the upper mold fixing block and pressure plate, pushing the aluminum casting rotor downward. At the same time, the lower mold pressure plate floats down, while the lower mold gate pressure block is positioned upward, squeezing and flattening the gate residue at the corresponding position of the aluminum casting rotor.

[0011] It quickly and efficiently removes residual gates from die-cast rotors, eliminating the risk of inconsistent residues and cuts caused by gate breakage. It is easy to operate and provides good consistency. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] A die-casting rotor gate device includes a base 1, guide components 2 on both sides of the base, a lower mold assembly on the base, and an upper mold assembly 4 that works in conjunction with the lower mold assembly 3. The lower mold assembly includes a lower mold gate pressing block 3.1 mounted on the base and a lower mold pressing plate 3.2 that can float up and down. The top surface of the lower mold pressing plate has several slots 3.3 evenly distributed for the protrusions of the die-casting rotor to be inserted, which facilitates the fixing and positioning of the die-casting rotor. A guide rod assembly and a guide pin assembly that abuts against the die-casting rotor are provided between the lower mold gate pressing block and the lower mold pressing plate. The guide pin assembly includes several guide pins 6 evenly distributed with the center of the lower mold gate pressing block as the center. One end of the guide pin abuts against an auxiliary block 7 inside the lower mold gate pressing block, and the other end passes through a through hole in the lower mold pressing plate and abuts against the die-casting rotor. When the lower mold pressing plate moves downward, since the guide pin is fixed on the auxiliary block, the downward pressure of the lower mold pressing plate causes the guide pin to press down against the die-casting rotor.

[0020] The guide rod assembly includes several lower mold ejector screws 5 evenly distributed around the center of the lower mold gate pressure block. One end of each lower mold ejector screw is inserted into the corresponding mounting hole in the lower mold pressure plate, and the other end is inserted into the mounting groove of the lower mold gate pressure block. During the up-and-down movement of the lower mold pressure plate, the lower mold ejector screws guide the lower mold pressure plate.

[0021] A butterfly spring 8 is provided around the lower mold unloading screw in the mounting groove. The butterfly spring is used for resetting and to float in conjunction with the lower mold pressure plate.
