Description

Technical Field

[0001] This utility model relates to the field of motor end cap die casting technology, specifically a die casting mold frame for motor end caps of new energy vehicles. Background Technology

[0002] The die-casting mold base is the basic support structure of the die-casting mold, equivalent to the "skeleton" of the mold. It is usually composed of components such as the fixed mold base plate, the moving mold base plate, the support plate, the pads, the guide pillars and guide sleeves, and the ejection mechanism. It provides installation and positioning for functional components such as the mold cavity, core, and gating system, and withstands the high pressure, high temperature, and mechanical impact loads during the die-casting process.

[0003] In the production process of motor end caps, which are mostly disc-shaped or annular thin-walled structures, the molds contain complex recessed areas. Manual spraying can easily result in blind spots, leading to problems such as mold sticking and surface defects, which directly affect demolding efficiency and product quality. Secondly, it is usually necessary to manually spray the mold with release agent. This manual operation results in a long spraying cycle and consumes a lot of time, making it difficult to meet the needs of large-scale production. Moreover, the diffusion of droplets is uncontrollable, with 30%-50% of the release agent drifting into the air or dripping onto the equipment surface, causing serious waste. To address these issues, the inventors have proposed a die-casting mold frame for new energy vehicle motor end caps to solve these problems. Utility Model Content

[0004] In order to solve the problem of automatic spraying and uniform coverage of release agent in the production process, the purpose of this utility model is to provide a die-casting mold frame for the end cover of the motor of new energy vehicle.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a die-casting mold frame for a motor end cover of a new energy vehicle, including a worktable, a top frame fixedly provided on one side of the top of the worktable, a lifting frame slidably connected between the top frame and the worktable through a guide rod, a stationary mold provided at the top of the worktable below the lifting frame, a moving mold fixedly provided at the bottom of the lifting frame for use in conjunction with the stationary mold, an automatic nozzle displacement assembly provided at the bottom of the lifting frame, a uniform spraying assembly provided at the end of the automatic nozzle displacement assembly for use in conjunction with the stationary mold and the moving mold, and an electric cylinder fixedly installed on the top frame, and the driving end of the electric cylinder is fixedly connected to the lifting frame.

[0006] Preferably, the uniform spraying assembly includes a fixed frame and two symmetrically distributed connecting frames. The fixed frame is slidably mounted on the top of the workbench. The two connecting frames are fixedly mounted on the upper and lower ends of the fixed frame near the stationary mold. Each connecting frame has a rotating shaft rotatably mounted on adjacent sides at the end. A rotating frame is fixedly connected between the two rotating shafts. Rotating cylinders are rotatably mounted on the middle of the inner walls of the rotating frame, and the two rotating cylinders are perpendicular to the two rotating shafts. Atomizing nozzles are fixedly mounted on adjacent sides of the two rotating cylinders. A driven shaft is rotatably mounted in the middle of the connecting frame. A rotating rod is fixedly connected to the end of the driven shaft near the atomizing nozzle. A fixed shaft is rotatably mounted at the end of the rotating rod, and the fixed shaft is fixedly mounted in the middle of the tail end of the atomizing nozzle. The fixed shaft is perpendicular to the atomizing nozzle. A drive shaft is rotatably mounted in the middle of the fixed frame, and the drive shaft is connected to the two driven shafts through a bevel gear set. A drive motor is fixedly mounted at the end of the fixed frame, and the drive end of the drive motor is coaxially fixedly connected to the drive shaft. A delivery hose is provided on one side of the outer wall of the fixed frame, and the drain end of the delivery hose passes through the wall of the rotating cylinder and is connected to the atomizing nozzle. The water inlet end of the delivery hose is connected to an external release agent supply device.

[0007] Preferably, the automatic nozzle displacement assembly includes a moving plate and a lifting plate. The moving plate is slidably mounted on the top of the worktable, and the lifting plate is fixedly mounted on the bottom end of the lifting frame near the moving plate. A guide plate is fixedly mounted on the bottom end of the moving plate near the lifting plate.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] 1. This utility model, by setting a uniform spraying component, enables two atomizing nozzles to rotate and spray synchronously at a certain tilt angle, which can cover the complex surface of the mold from multiple angles, effectively solving the problem that traditional spraying is difficult to cover the recessed areas, significantly reducing the risk of mold sticking and improving the yield of die-cast parts.

[0010] 2. This utility model, by setting an automatic nozzle displacement component, accurately realizes the automatic positioning function of the atomizing nozzle during the mold opening process. The automatic nozzle displacement component uses the moving plate and the lifting plate as the core transmission components. Through the cooperation of the inclined groove and the guide wheel, the vertical movement of the mold opening and closing is converted into the horizontal movement of the nozzle. The atomizing nozzle can be moved in a directional manner without an additional power source, thereby improving the efficiency of mold release agent spraying. Attached Figure Description

[0022] The uniform spraying assembly 7 includes a fixed frame 71 and two symmetrically distributed connecting frames 72. The fixed frame 71 is slidably mounted on the top of the workbench 1. The two connecting frames 72 are respectively fixedly mounted on the upper and lower ends of the fixed frame 71 near the stationary mold 4. The adjacent sides of the ends of the connecting frames 72 are rotatably provided with rotating shafts 73. A rotating frame 74 is fixedly connected between the two rotating shafts 73.

The fixed shaft 79 is fixedly installed in the middle of the tail end of the atomizing nozzle 76. The fixed shaft 79 is perpendicular to the atomizing nozzle 76.

[0023] By adopting the above technical solution, the driven shaft 77 rotates, causing the atomizing nozzle 76 to tilt and rotate at a certain angle.

[0024] The automatic nozzle displacement assembly 6 includes a moving plate 61 and a lifting plate 62. The moving plate 61 is slidably installed on the top of the workbench 1, and the lifting plate 62 is fixedly installed on the bottom of the lifting frame 3 near the moving plate 61. A guide plate 63 is fixedly installed on the bottom of the moving plate 61 near the lifting plate 62. A guide shaft 65 is fixedly installed in the middle of the outer wall of the guide plate 63, and the guide shaft 65 is slidably installed on the lifting plate 62.

[0025] By adopting the above technical solution, the lifting plate 62 drives the moving plate 61 to move synchronously during the lifting process.

[0026] Two symmetrically distributed brackets 64 are fixedly installed at the top of the movable plate 61, and the fixed frame 71 is fixedly installed at the top of the brackets 64.

[0027] By adopting the above technical solution, the movable plate 61 drives the fixed frame 71 to move synchronously.

[0028] A drive shaft 710 is rotatably mounted in the middle of the fixed frame 71, and the drive shaft 710 is connected to two driven shafts 77 via a bevel gear set.

[0029] By adopting the above technical solution, the drive shaft 710 drives the two driven shafts 77 to rotate synchronously.

[0030] A drive motor 711 is fixedly mounted on the end of the fixed frame 71, and the drive end of the drive motor 711 is coaxially and fixedly connected to the drive shaft 710.

[0031] A conveying hose is provided on one side of the outer wall of the fixed frame 71, and the drain end of the conveying hose passes through the wall of the rotating cylinder 75 and is connected to the atomizing nozzle 76. The water inlet end of the conveying hose is connected to the external release agent supply device.

[0032] By adopting the above technical solution, the drive motor 711 drives the drive shaft 710 to rotate continuously, providing a power source.

[0033] A slide rail 69 is fixedly installed on one side of the top of the workbench 1, and a slider is slidably mounted on the slide rail 69. The moving plate 61 is fixedly connected to the slider.

[0034] By adopting the above technical solution, the movable plate 61 slides laterally under the guidance of the slide rail 69.

[0035] The lifting plate 62 has an inclined groove 66, which is designed to be inclined upward. The lifting plate 62 has a vertical groove 67 near the top of the inclined groove 66, and the vertical groove 67 is connected to the top of the inclined groove 66.

[0036] A guide wheel 68 is rotatably sleeved on the outer wall of the guide shaft 65, and the guide wheel 68 is slidably installed in the inclined groove 66 and the vertical groove 67.

[0037] By adopting the above technical solution, the guide wheel 68 slides in the inclined groove 66, thereby driving the guide shaft 65 to move laterally.

[0038] The workbench 1 is provided with a storage slot 610 that works in conjunction with the lifting plate 62.

[0039] By adopting the above technical solution, the lifting plate 62 is lowered into the storage slot 610.

[0040] Working principle: In practical application, the mold is opened first. The drive end of the electric cylinder 8 is controlled to retract, which drives the moving mold 5 to rise and open the mold. The lifting plate 62 rises synchronously with the lifting frame 3. During this process, the guide wheel 68 fixed on the lifting plate 62 slides from the vertical groove 67 into the inclined groove 66. Due to the upward inclined design of the inclined groove 66, when the guide wheel 68 slides along the inclined groove 66, it pushes the guide shaft 65 to move laterally, which in turn drives the moving plate 61 to move along the slide rail 69 towards the mold to the end. At this time, the two atomizing nozzles 76 are located in the middle position between the stationary mold 4 and the moving mold 5.

[0041] Then, a release agent is sprayed into the cavity between the stationary mold 4 and the moving mold 5. The external release agent supply device delivers the release agent to the atomizing nozzle 76 through a delivery hose. The release agent is atomized and sprayed out through the atomizing nozzle 76. At the same time, the drive motor 711 is turned on. The drive end of the drive motor 711 drives the drive shaft 710 to rotate. The drive shaft 710 drives the two driven shafts 77 to rotate synchronously through the bevel gear set. The driven shafts 77 drive the rotating rod 78 to rotate synchronously. The fixed shaft 79 pushes the atomizing nozzle 76. Under the coordinated action of the connecting frame 72, the rotating shaft 73, the rotating frame 74 and the rotating cylinder 75, the nozzle rotates at a certain tilt angle.

[0042] After the spraying is completed, the electric cylinder 8 drives the lifting frame 3 to descend, causing the moving mold 5 and the stationary mold 4 to close. The guide wheel 68 slides from the vertical groove 67 back to the inclined groove 66. Under the action of gravity and mold reset force, the moving plate 61 returns to the initial position along the slide rail 69. This cycle is repeated to perform automated and uniform spraying.

[0043] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
