Description

Technical Field

[0001] This utility model relates to the field of casting machine technology, specifically to a gravity casting machine for automotive aluminum alloy pressure shells. Background Technology

[0002] Gravity casting is a process in which molten metal is poured into a metal mold under the influence of Earth's gravity to obtain castings. Currently, gravity casting machines are used to cast parts such as aluminum alloy housings for automobiles. Gravity casting machines include tilting casting machines, which can drive the metal mold to rotate, allowing the high-temperature molten metal to fill various parts of the metal mold relatively evenly with the assistance of external force.

[0003] The metal mold in the tilting casting machine adopts an upper mold plus a lower mold structure, which is opened and closed by a cylinder. The lower mold is equipped with an ejector cylinder for discharging the casting. When the metal mold in the tilting casting machine is stationary, it may be tilted or inclined. In this case, after the casting is discharged, it will move towards the tilted end of the mold, causing the casting discharge path to deviate. In some cases, the casting may even fall outside the tilting casting machine under the action of gravity and tilt, resulting in an unstable casting discharge path. To address the shortcomings of the existing technology, we propose a gravity casting machine for automotive aluminum alloy shells to solve the above problems. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] This application provides a gravity casting machine for automotive aluminum alloy housings, which solves the problem that when the metal mold of a tilting casting machine is stationary, it may be tilted or inclined. In this case, after the casting is discharged, it will move towards the tilted end of the mold, causing the casting discharge path to deviate. In some cases, the casting may even fall outside the tilting casting machine under the action of gravity and tilt, resulting in an unstable casting discharge path. This invention achieves stable casting discharge from the tilting casting machine in any state.

[0026] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0027] This utility model discloses a gravity casting machine for automotive aluminum alloy pressure shells.

[0028] According to the appendix Figure 1-6As shown, the system includes a base 1, a support 11 mounted on the top surface of the base 1, a main frame 2 rotatably mounted on the top surface of the support 11, a lower mold 3 and an upper mold 4 mounted inside the main frame 2, and a rotating cylinder 12 positioned between the main frame 2 and the base 1. A casting port is located at the upper mold 4. A hydraulic cylinder 41 controlling the movement of the upper mold 4 is located on one side of the main frame 2, and an ejector cylinder 31 discharging the formed automotive aluminum alloy shell is located on the other side of the main frame 2. The base 1, support 11, main frame 2, lower mold 3, upper mold 4, and rotating cylinder 12 constitute a gravity casting machine of the brand Kuntai. It can rotate 90 degrees, allowing the high-temperature molten metal to flow within the assembled lower mold 3 and upper mold 4, ensuring that the high-temperature molten metal is evenly poured into various positions within the assembled mold. Specifically... First, the upper mold 4 and the lower mold 3 are closed by the hydraulic cylinder 41. Then, high-temperature molten metal is poured into the closed upper mold 4 and the lower mold 3 through the casting port. Then, the rotating cylinder 12 is turned on, so that the rotating cylinder 12 controls the main frame 2 and the upper mold 4 and the lower mold 3 at the main frame 2 to rotate along the support 11, so that the high-temperature molten metal can flow to various positions in the closed upper mold 4 and the lower mold 3. After the internal parts of the closed upper mold 4 and the lower mold 3 are cooled and formed, the required automotive aluminum alloy press shell is formed. The automotive aluminum alloy press shell is not specifically shown in the attached figure. Next, the ejector cylinder 31 set at the lower mold 3 is turned on, so that the ejector cylinder 31 pushes the automotive aluminum alloy press shell to the outside of the lower mold 3, and the cast automotive aluminum alloy press shell is discharged.

[0029] See attached document Figure 2-6 A receiving mechanism 5 is provided on one side of the main frame 2, and the lower mold 3 and upper mold 4 are as shown in the attached figure. Figure 1 When the lower mold 3 and upper mold 4 are tilted, or when the rotation angle of the lower mold 3 and upper mold 4 is less than 90 degrees, the lower mold 3 and upper mold 4 are tilted. At this time, when the ejector cylinder 31 ejects the automotive aluminum alloy press shell, the ejection path of the automotive aluminum alloy press shell will be deviated. At this time, the set receiving mechanism 5 can limit and support the ejection path of the automotive aluminum alloy press shell and assist the ejection of the automotive aluminum alloy press shell. The receiving mechanism 5 includes a side frame 51, which is fixedly connected to one side of the main frame 2, as shown in the attached figure. Figure 3 As shown, the receiving plate 52 is slidably disposed inside the side frame 51, and a push cylinder 53 for controlling the movement of the receiving plate 52 is provided on one side of the side frame 51. (Refer to the attached diagram) Figure 5-6The extension plate 54 and the receiving plate 52 are telescopically connected. The receiving plate 52 has an adjusting screw 55 inside to control the extension length of the extension plate 54. A threaded block 551, threaded to the outer wall of the adjusting screw 55, is fixedly installed on the bottom surface of the extension plate 54. A limiting groove 56 is provided on the inner wall of the receiving plate 52 for limiting the adjusting screw 55 and the threaded block 551. When the upper mold 4 moves away from the lower mold 3 under the drive of the hydraulic cylinder 41, the receiving plate 52 adjusts according to the different distances between the upper mold 4 and the lower mold 3. The extension plate 54 is adjusted in length so that one end of the receiving plate 52 abuts against one side of the lower mold 3 and one end of the extension plate 54 abuts against one side of the upper mold 4. This ensures that the automotive aluminum alloy shell ejected by the ejector cylinder 31 can be accurately moved to the surface of the extended plate 54 and the receiving plate 52 after the extension plate 54 and the receiving plate 52 are adjusted in length. Then, the extended plate 54 and the receiving plate 52 after the extension plate 54 and the receiving plate 52 can continue to position and eject the automotive aluminum alloy shell with the assistance of the push cylinder 53. The limiting groove 56 is provided with a guide rod 57 to assist the directional movement of the extension plate 54.

[0030] See attached document Figure 2-4 An opening 7 is provided at one end of the side frame 51 near the end of the adjusting screw 55. A through hole 71 corresponding to the position of the opening 7 is provided on one side of the main frame 2. Through the through hole 71 and the opening 7, when the adjusting screw 55 is rotated, the operator's hand can grasp the control end of the adjusting screw 55 through the through hole 71 and the opening 7, thereby driving the adjusting screw 55 to rotate, so as to adjust the extension length of the receiving plate 52 and the extension plate 54.

[0031] See attached document Figure 4-5 An auxiliary component 6 is provided at one end of the extension plate 54. When one end of the extension plate 54 moves out of the interior of the receiving plate 52, the auxiliary component 6 provides auxiliary support to the end of the extension plate 54 away from the receiving plate 52, ensuring that the receiving plate 52 and the extension plate 54 are in a stable state after the telescopic adjustment. The auxiliary component 6 includes a limiting plate 61 fixedly installed at one end of the extension plate 54, a movable plate 62 that limits sliding inside the side frame 51, and a telescopic rod 63 installed between the limiting plate 61 and the movable plate 62. The frame 51 has a slide rail 64 inside. One end of the movable plate 62 is limited to slide inside the slide rail 64. When the extension plate 54 moves away from the receiving plate 52, it will drive the limiting plate 61 at one end of the extension plate 54 to move, and then drive the movable plate 62 connected to the lower part of the limiting plate 61 to move. When the push cylinder 53 pushes the receiving plate 52 to move, the telescopic rod 63 between the limiting plate 61 and the movable plate 62 will extend by an equal length, so that the telescopic rod 63 provides stable support for one end of the extension plate 54.
