[0001] The utility model relates to the technical field of rotor die-casting, in particular to a rotor die-casting sleeve and a rotor die-casting structure. Background Art

[0002] The rotor is a rotating body supported by bearings. It is the main rotating component in power machinery and working machinery such as motors and turbines. Therefore, it is a very important component in motors and similar working machinery. In the process of rotor processing and preparation, die casting is required, which is called rotor die casting.

[0003] Rotor die-casting‌ is a die-casting process primarily used to manufacture rotor components. This process involves pouring molten metal into a die-casting mold and then injecting the solution into the mold cavity via an injection cylinder. Meanwhile, the rotor die-casting sheath‌ is a new processing technology designed to address the high cost of existing processing methods. It utilizes a hollow cylindrical structure that can encase the rotor core placed within the cylindrical structure when closed, and allow the rotor core to be removed after opening. However, removing the core during the opening and closing process can easily damage the cylindrical mold during repeated processing, which can directly affect the service life of the cylindrical mold.

However, when the core is taken out during the opening and closing process, it is easy to cause damage to the cylindrical mold during repeated processing, which can directly affect the service life of the cylindrical mold.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rotor die-casting sleeve and a rotor die-casting structure, including a workbench, a top plate, and a stand. A discharge seat is installed at the right position on the top of the workbench. A positioning groove is provided in the top of the discharge seat. A cylindrical mold can be placed in the positioning groove. A forming groove is provided inside the cylindrical mold. Limiting blocks are fixed at positions near the bottom on both sides of the inner wall of the forming groove. A movable plate is placed on the top of the limiting block. A top block is fixed on the top of the movable plate. A first telescopic rod is installed in the discharge seat. The top of the first telescopic rod is connected to a push plate. A column is fixed on the top of the push plate. A circular hole groove is provided in the bottom of the positioning groove.

[0006] Preferably, the number of the circular hole grooves is the same as the number of the columns, and the diameter of the circular hole grooves is larger than the diameter of the columns.

[0007] Preferably, the forming grooves are distributed in an annular manner in four groups in the cylindrical mold, and the columns are distributed in an annular manner in four groups on the top end of the push plate.

[0008] Preferably, the limiting blocks are symmetrically distributed about the central axis of the forming groove, and the circular hole grooves are annularly distributed in four groups within the positioning groove.

[0009] Preferably, a transmission disk is installed on the left side of the top of the workbench, and the bottom of the transmission disk is connected to a first motor.

[0011] Preferably, a transmission seat is installed on the top of the workbench at a position on the side of the discharge seat, the bottom end of the transmission seat is connected to a second motor, an adjustment box is installed on the top of the transmission seat, a servo motor is installed on the top of the adjustment box, a threaded rod is installed inside the adjustment box, a guide groove is opened in the side of the adjustment box, a threaded block is connected to the outer wall of the threaded rod, a connecting plate is installed on the side of the threaded block using the guide rod, and a connecting plate is installed on the bottom end of the connecting plate.

[0012] Preferably, a sliding groove is opened in the bottom of the connecting plate, a slider is embedded in the inside of the sliding groove, a clamping plate is fixed to the bottom end of the slider, and an anti-slip pad is glued and fixed to the side of the clamping plate. Vertical plates are installed on both sides of the bottom of the connecting plate, and the sides of the vertical plates are connected to the second telescopic rod, forming a sliding connection between the sliding groove and the slider.

[0013] Compared with the prior art, the beneficial effects of the present invention are: the rotor die-casting sleeve and the rotor die-casting structure not only improve the discharge capacity, but also improve the transfer capacity and processing capacity of the die-casting structure;

[0014] The die-cast cylindrical mold is transferred to the position of the discharge seat, and the cylindrical mold is placed inside the positioning groove. According to the placement orientation, the molding groove is made to correspond to the circular hole groove in the bottom of the positioning groove. The lower positions of both sides of the molding groove are fixed with limit blocks, and the movable plate is placed above the limit blocks. Therefore, the upward area of ​​the movable plate in the molding groove is the molding area. When the cylindrical mold is placed in the positioning groove, the first telescopic rod in the discharge seat is started to drive the push plate to move up and down. Since the position of the column corresponds to the circular hole groove, the upward pressure is applied to the movable plate when the column moves upward, so that the material can be ejected upward, thereby better improving the overall discharge capacity during the work process.

[0015] The cylindrical mold is first placed in the placement groove in the transmission disk, and then the first motor is started to drive the transmission disk to rotate. After the die-casting is completed, the processed cylindrical mold can be rotated to the position directly below the connecting plate, and then the servo motor is started to drive the threaded rod to rotate. The threaded rod and the threaded block cooperate with each other to form a vertical position adjustment, and the height position of the connecting plate is adjusted under the connection of the guide rod. After the connecting plate is lowered, the clamping plate reaches the positions on both sides of the placement groove in the transmission disk, specifically the gap between the placement groove and the cylindrical mold. Then, the second telescopic rod is started to work and the spacing of the clamping plates is adjusted to clamp the cylindrical mold. After clamping, it is moved up as a whole, and then the second motor is started to drive the transmission seat to rotate. After the cylindrical mold is transferred to the position directly above the discharge seat, it is adjusted to move down as a whole again, thereby better improving the overall transportation capacity during the work process.

[0016] By installing and fixing the positioning column at the bottom end of the placement groove, and then using the slot and the positioning column to complete the positioning assembly of the holding plate, the cylindrical mold can be directly placed above the holding plate, and the solution is injected into the cylindrical mold through the injection cylinder. The injection cylinder can be located at the back end of the workbench. Then, after the cylinder is started, it can drive the hydraulic telescopic rod to extend and retract, allowing the die-casting plate to gradually move down to the top of the cylindrical mold, thereby better improving the overall die-casting capacity during the work process.
