Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a die-casting gate structure for a dynamic balance plate of a new energy motor. Background Technology

[0002] New energy motors refer to motors that use new energy sources as their power source. In new energy vehicles, the new energy motor is the main drive motor, responsible for all functions related to vehicle movement. Before a new energy motor is put into use, the two calibration surfaces of the motor rotor need to be simultaneously calibrated and balanced. A motor dynamic balancing plate is a device used to detect and correct the dynamic balance of rotating machinery (such as motor rotors, fan impellers, main shafts, etc.). Its core principle is to measure the imbalance (amplitude and phase) of rotating components, and then eliminate vibration by adding or removing counterweights or adjusting their positions, ensuring smooth operation of the equipment.

[0003] like Figure 1 This is a dynamic balancing plate for a new energy motor (a circular aluminum plate with a central hole), including the plate body 22. During die casting, molten aluminum flows from the pouring channel to the gate and finally enters the mold cavity from the gate. The common pouring channel is "Y" shaped. During the die casting process, after the molten aluminum enters the mold cavity from the gate, it spreads to the surrounding area. This results in insufficient molten aluminum near the gate after the product is finally formed, leading to inconsistent overall thickness of the product and affecting its quality. This needs to be improved. Utility Model Content

[0004] To address the issue of thinner thickness near the gate in the die-casting process of motor dynamic balance plates, this application provides a die-casting gate structure for dynamic balance plates of new energy motors.

[0005] The technical solution provided in this application for a die-casting gate structure for a dynamic balance plate of a new energy motor is as follows:

[0006] A die-casting gate structure for a dynamic balance plate of a new energy motor includes a fixed mold and a moving mold. The moving mold has a mold core, which includes a first mold and a second mold disposed on the first mold. A forming cavity is formed on one side of the first mold and the second mold opposite to each other. The moving mold has a gating pipe with a gating gate. The first mold has a gating channel and a gate. The gating channel connects the gating gate and the gate. The gate has a flow-dividing protrusion located on the side of the gate near the forming cavity and on the central axis of the gate cross-section.

[0007] Preferably, the gate includes a first casting cavity and a second casting cavity, the first casting cavity and the second casting cavity being separated by a diversion protrusion on the side near the molding cavity; both the first casting cavity and the second casting cavity extend toward the center of the molding cavity.

[0008] Preferably, the first mold is provided with an installation groove, the installation groove is located at the center of the molding cavity, the installation groove is provided with a first slag bag, the first slag bag is provided with a connecting part, and the connecting part connects the first slag bag and the molding cavity.

[0009] Preferably, the first mold is provided with a second slag bag, the second slag bag is located outside the molding cavity, and the second slag bag is connected to the molding cavity.

[0010] Preferably, the first mold is provided with an exhaust channel, and the exhaust channel is provided with a third slag bag, which is connected to the molding cavity; the moving mold is provided with an exhaust block, which is used for exhausting air and is connected to the exhaust channel.

[0011] Preferably, a mounting plate is slidably connected to the fixed mold, the mounting plate is provided with an ejector plate, and the ejector plate is provided with a plurality of ejector pins for ejecting the product; the fixed mold is provided with an installation port for mounting a hydraulic cylinder to drive the mounting plate to move.

[0012] Preferably, the fixed mold is provided with guide blocks, which pass through the mounting plate and the ejector plate, and the guide blocks are located on both sides of the fixed mold.

[0013] The main technical effects of this utility model are reflected in the following aspects:

[0014] 1. This utility model increases the number of gates from one to two by setting a diversion protrusion. The first and second pouring chambers will simultaneously inject molten aluminum into the molding cavity. Since the extension direction of the first and second pouring chambers is towards the center of the molding cavity, the molten aluminum will not immediately spread to both sides when it is injected. The molten aluminum injected into the first and second pouring chambers will gradually merge, so that the position near the gate is filled first. At the same time, the molten aluminum spreads outward to fill the molding cavity, and finally forms a product with uniform thickness, ensuring the quality of the product.

[0015] 2. This utility model prevents excessive collision between the two molten aluminum streams when they converge, thus ensuring the molding quality of the product.

[0016] 3. This utility model uses a second slag bag and a third slag bag to collect impurities, cold shut materials and gases in the molten metal, thereby improving product quality. Attached Figure Description

A pouring pipe 5 is fixed on the moving mold 2, and a pouring port 6 is provided on the pouring pipe 5. A pouring channel 7 is provided on the first mold 31, and a gate 8 is also provided on the first mold 31. The pouring channel 7 connects the pouring port 6 and the gate 8. Molten aluminum enters the pouring channel 7 from the pouring port on the pouring pipe 5, and then enters the forming cavity 4 through the gate 8 to form a motor dynamic balancing plate. The motor dynamic balancing plate is then trimmed to obtain the target metal part (motor dynamic balancing plate).

[0029] Reference Figure 5 A flow-diverting protrusion 9 is fixed on the gate 8, located on the side of the gate 8 closest to the molding cavity 4, and situated on the central axis of the gate 8's cross-section. The gate 8 includes a first casting cavity 81 and a second casting cavity 82, separated from the molding cavity 4 by the flow-diverting protrusion 9. Both the first casting cavity 81 and the second casting cavity 82 extend towards the center of the molding cavity 4. When the die-cast center portion of the product is solid, the dual-gate structure of this application can make the center portion of the product fuller, improving product quality.

[0031] Reference Figure 5 A second slag bag 13 is installed on the first mold 31. The second slag bag 13 is located outside the molding cavity 4 and is connected to the molding cavity 4.

[0032] Reference Figure 5 The first mold 31 has an exhaust channel 14, and a third slag bag 15 is installed on the exhaust channel 14. The third slag bag 15 is connected to the molding cavity 4. An exhaust block 16 is fixed on the moving mold 2. The exhaust block 16 is used for exhaust and is connected to the exhaust channel 14.

[0033] Reference Figure 6 and Figure 7 A mounting plate 17 is slidably connected to the fixed mold 1. The sliding direction of the mounting plate 17 is horizontal. An ejector plate 18 is mounted on the mounting plate 17, and several ejector pins 19 are fixed on the ejector plate 18 for ejecting products. The fixed mold 1 has a mounting opening 20 for mounting a hydraulic cylinder to move the mounting plate 17, thereby simultaneously moving the ejector plate 18. A guide block 21 is fixed on the fixed mold 1, passing through the mounting plate 17 and the ejector plate 18, and is located on both sides of the fixed mold 1.
