[0004] Due to the special structure of the workpiece, the internal shape of the mold cavity is relatively complex.

Summary of the invention

During the casting process, the molten aluminum needs to flow into every corner of the mold cavity. However, as the molten aluminum flows, its temperature will decrease, so the flow speed will slow down, which will not only reduce the casting speed, but also the molten aluminum may not be able to flow evenly into every corner of the mold, which may cause defects in the casting, such as shrinkage cavities, shrinkage porosity, etc.

[0007] Beneficial effects: The telescopic rod has two states, namely, the discharge state and the working state. In the discharge state, the telescopic rod and the mounting column are both in a vertical state, and the driving motor does not work at this time; in the working state, the electric push rod drives the slider to slide along the slide rail, so that the telescopic rod and the mounting column are in an inclined state, and the bearing seat and the casting mold are both in an inclined state. The driving motor drives the slide rail to rotate, so that the casting mold continuously swings around the axis extending in the left and right directions of the rotating frame and the axis extending in the front and back directions. When the bearing seat drives the casting mold to tilt, the upper telescopic tube will be elongated, and at the same time, the first discharge ball and the lower connecting seat rotate, and the second discharge ball and the upper connecting seat also rotate, and the state can be maintained for swinging. The feeding hopper can remain motionless, so it does not affect the addition of aluminum liquid by the ladle, and the casting mold can be continuously swung while casting. It can accelerate the flow of aluminum liquid in the casting mold cavity, and at the same time, it can make the aluminum liquid fully flow into every corner, avoiding defects such as shrinkage holes and shrinkage in the casting.

[0008] Preferably, the clamping unit comprises a threaded rod screwed onto the bearing seat, and a positioning plate is rotatably mounted on the end of the threaded rod.

[0009] The effect is that the casting mold can be clamped to prevent it from falling off during operation.

[0010] Preferably, the driving member is a driving motor fixedly mounted on the base, and the slide rail is fixedly mounted on the output end of the driving motor.

[0011] Preferably, an electric push rod is installed on the slide rail, and the telescopic part of the electric push rod is fixedly connected to the slide block.

[0014] The effect is that both the lower telescopic tube and the upper telescopic tube have telescopic functions, ensuring that the casting operation can be carried out during the swinging process of the casting mold.

[0015] Preferably, a baffle ring is provided on the inner side of the lower telescopic tube, a baffle plate is installed movably below the baffle ring, a connecting rod with an L-shaped structure is fixedly installed above the baffle plate, a through avoidance long hole is opened on the side wall of the lower telescopic tube, and a sealing slide is installed inside the lower telescopic tube along its axial direction, the horizontal part of the connecting rod passes through the sealing slide, and the connecting rod is fixedly connected to the sealing slide, a spring is provided on the horizontal part of the connecting rod, and the spring is fixedly connected to the lower telescopic tube at one end away from the connecting rod.

[0016] The effect is that when the liquid approaches the upper end of the casting hole, the molten aluminum in the casting hole will gradually cover the plug plate, thereby offsetting the downward thrust of the plug plate when adding molten aluminum. The spring pulls the plug plate upward to reset it, thereby closing the hole on the retaining ring and stopping the further addition of molten aluminum into the casting hole, avoiding waste of molten aluminum.

[0017] Preferably, the plug plate has an arc-shaped cross-section and is made of ceramic material.

[0018] The effect is that the aluminum liquid can slide down quickly when passing through the surface of the plug plate without any residue or adhesion.

[0019] By adopting the above technical scheme, the beneficial effects of the present invention are as follows: during operation, the electric push rod drives the slider to slide along the slide rail, so that the telescopic rod and the mounting column are in an inclined state, the bearing seat and the casting mold are in an inclined state, and the driving motor drives the slide rail to rotate, so that the casting mold continuously swings around the axis extending in the left and right directions of the rotating frame and the axis extending in the front and rear directions. When the bearing seat drives the casting mold to tilt, the upper telescopic tube will be elongated, and at the same time, the first discharge ball and the lower connecting seat will rotate, and the second discharge ball and the upper connecting seat will also rotate, and this state can be maintained for swinging. The feeding hopper can remain stationary, so it does not affect the addition of aluminum liquid by the ladle, and the casting can be performed while the casting mold is continuously swung. It can accelerate the flow of aluminum liquid in the casting mold cavity, and at the same time, it can make the aluminum liquid fully flow into every corner, avoiding the occurrence of shrinkage holes, shrinkage and other defects in the casting.

[0028] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0029] like Figures 1 to 7 As shown, a specific embodiment of a shock absorber aluminum cylinder casting auxiliary device of the present invention includes a supporting module, a swing module, a bearing module, a feeding module and an adjusting module.

[0030] like Figure 1 and Figure 2 As shown, the support module includes a base 10 , on which a mounting frame 11 is fixedly mounted. The mounting frame 11 is generally in a U-shaped structure, and a charging hopper 12 is fixedly mounted on the top of the mounting frame 11 .

[0031] like Figure 5 The swing module includes a mounting base 20 fixedly mounted on the base 10, and supports 21 are symmetrically mounted on the mounting base 20. A driving motor 22 is fixedly mounted on the upper surface of the mounting base 20, and a slide rail 23 is fixedly mounted on the output end of the driving motor 22, so that the driving motor 22 can drive the slide rail 23 to rotate.

[0032] A slider 24 is slidably mounted on the slide rail 23 , and an electric push rod connected to the slider 24 is mounted on the slide rail 23 , and the slider 24 can be driven to slide along the slide rail 23 by the electric push rod.

[0033] A connecting rotating plate 25 is rotatably mounted on the slider 24 along an axis extending in the front-rear direction, a telescopic rod 26 is fixedly mounted on the connecting rotating plate 25, and a mounting column 27 is rotatably mounted on the upper end of the telescopic rod 26, and the mounting column 27 is arranged vertically.

[0034] A rotating frame 29 is arranged inside the support 21. The rotating frame 29 is roughly square in structure. The central positions of the two rods opposite to each other in the left and right directions of the rotating frame 29 are both provided with rotating seats, and the two rotating seats are respectively rotatably matched on the supports 21 on both sides. In other words, the rotating frame 29 can rotate along the axis extending in the left and right directions of the rotating seat.

[0035] The center positions of the two rod bodies opposite to each other in the front-to-back direction of the rotating frame 29 are also provided with a rotating seat. The mounting post 27 is located at the center position of the inner side of the rotating frame 29. The mounting post 27 is fixedly provided with a rotating shaft 28. The rotating shaft 28 penetrates the mounting post 27 from front to back and is arranged horizontally. The front and rear ends of the rotating shaft 28 are respectively rotatably matched with the rotating seat in the front-to-back direction of the rotating frame 29, so that the mounting post 27 can rotate along the axis extending in the front-to-back direction of the rotating shaft 28. At the same time, the rotating frame 29 can also drive the mounting post 27 to rotate along the axis extending in the left-to-right direction of the rotating seat. Therefore, the mounting post 27 can rotate in four directions: front, back, left, and right.

[0036] It is particularly noted that the axis of the rotating frame 29 extending along the left-right direction of the rotating seat and the axis extending along the front-back direction of the rotating seat are on the same horizontal plane.

[0037] The telescopic rod 26 and the mounting column 27 have two states, namely, a discharge state and a working state. In the discharge state, the telescopic rod 26 and the mounting column 27 are both in a vertical state, and the drive motor 22 is not working at this time; in the working state, the electric push rod drives the slider 24 to slide along the slide rail 23, so that the telescopic rod 26 and the mounting column 27 are in an inclined state (such as Figure 6 ), the telescopic rod 26 will be stretched, and the driving motor 22 drives the slide rail 23 to rotate, so that the telescopic rod 26 rotates in an inclined state around the axis of the output shaft of the driving motor 22. At the same time, the mounting column 27 can continuously swing around the axis extending in the left and right directions and the axis extending in the front and rear directions of the rotating frame 29.

[0038] like Figure 1 , Figure 2 and Figure 4 The bearing module includes a bearing seat 30 fixedly mounted on the upper end of the mounting column 27 . The bearing seat 30 is used to place the casting mold 60 . A bracket 33 is fixedly mounted on the bearing seat 30 .

[0039] A threaded rod 31 is threadedly connected to the side of the bearing seat 30, and a positioning plate 32 is rotatably installed at one end of the threaded rod 31 located inside the bearing seat 30. After the casting mold 60 is placed on the bearing seat 30, the threaded rod 31 is rotated so that the positioning plate 32 clamps and fixes the casting mold 60.

[0040] Therefore, when the mounting column 27 continuously swings around the axis extending in the left-right direction and the axis extending in the front-back direction of the rotating frame 29, it can drive the supporting seat 30 and the casting mold 60 to swing continuously, which can accelerate the flow of molten aluminum in the cavity of the casting mold 60 and enable the molten aluminum to fully flow into every corner.

[0041] like Figure 1 , Figure 2 and Figure 6 As shown, the feed module includes a lower telescopic tube 40 fixedly mounted on a bracket 33. The lower telescopic tube 40 is arranged vertically and is composed of a plurality of telescopic units that are sealed and slidably matched.

[0042] An electric push rod is fixedly installed on the bracket 33, and the telescopic part of the electric push rod is fixedly connected to the telescopic unit at the bottom of the lower telescopic tube 40, so that when the casting mold 60 is placed on the supporting seat 30, the electric push rod can drive the lower telescopic tube 40 to descend, so that the liquid outlet at the lower end of the lower telescopic tube 40 enters the casting hole of the casting mold 60.

[0043] A first material-discharging ball 41 is fixedly mounted on the upper end of the lower telescopic tube 40, and a through hole is formed on the first material-discharging ball 41. The first material-discharging ball 41 is connected to the lower telescopic tube 40 through the through hole.

[0044] A lower connecting seat 42 with an opening is rotatably mounted outside the first material discharge ball 41 . The lower connecting seat 42 is a hemispherical structure, so that the first material discharge ball 41 and the lower connecting seat 42 can rotate at multiple angles.

[0045] The lower connecting seat 42 is connected with an upper telescopic tube 43, which is also composed of a plurality of telescopic units that are sealed and slidably matched. A second material discharge ball 44 is fixedly mounted on the upper end of the upper telescopic tube 43, and the second material discharge ball 44 has a through hole that passes through from top to bottom. The second material discharge ball 44 is connected with the upper telescopic tube 43 through the through hole thereon.

[0046] An upper connecting seat 45 with an opening is rotatably mounted outside the second material-discharging ball 44 . The upper connecting seat 45 is a hemispherical structure, so that the second material-discharging ball 44 can be rotated at multiple angles in the upper connecting seat 45 .

[0047] The upper connecting seat 45 is fixedly connected to the bottom of the feeding hopper 12 and is connected to the feeding hopper 12, so that the ladle can add molten aluminum into the feeding hopper 12, and the molten aluminum enters the lower telescopic tube 40 after passing through the upper telescopic tube 43, and then flows into the casting hole of the casting mold 60 through the lower telescopic tube 40.

[0048] like Figure 7 As shown, when the bearing seat 30 drives the casting mold 60 to tilt, the upper telescopic tube 43 will be stretched, and at the same time, the first material ball 41 and the lower connecting seat 42 rotate, and the second material ball 44 and the upper connecting seat 45 also rotate, so as to ensure the swing of the bearing seat 30.

[0049] The feeding hopper 12 can remain stationary, so it does not affect the addition of aluminum liquid by the ladle, and the casting mold 60 can be continuously swung around the axis extending in the left-right direction and the axis extending in the front-back direction of the rotating frame 29 while casting. The flow of aluminum liquid in the cavity of the casting mold 60 can be accelerated, and the aluminum liquid can be fully flowed into every corner of the cavity of the casting mold 60, avoiding defects such as shrinkage cavities and shrinkage in the casting.

[0050] In the traditional casting process, the aluminum liquid will overflow to the outside of the casting hole when pouring, so that the aluminum liquid is attached with gravel, resulting in waste of aluminum liquid. Therefore, the present invention solves this problem through an adjustment module, as follows.

[0051] like Figure 2 , Figure 3 and Figure 6 As shown, the adjustment module includes a retaining ring 50 fixed on the inner side of the lower telescopic tube 40. The retaining ring 50 is annular in structure and is located near the opening at the lower end of the lower telescopic tube 40. A plug plate 51 is installed below the retaining ring 50 so as to be liftable. The cross-section of the plug plate 51 is an arc-shaped structure. When the plug plate 51 abuts against the retaining ring 50, it can seal the hole in the center of the retaining ring 50.

[0052] In other embodiments, the plug plate 51 may also be a spherical structure.

[0053] In this embodiment, the plug plate 51 is made of ceramic material, so that the aluminum liquid can slide down quickly when passing through its upper surface without leaving any residue or adhesion.

[0054] A connecting rod 52 is fixedly installed above the plug plate 51, and the connecting rod 52 is in an L-shaped structure.

[0055] A through avoidance long hole is opened on the side wall of the lower telescopic tube 40, and a sealing slide plate 53 is installed inside the lower telescopic tube 40 along its axial sliding direction. The sealing slide plate 53 can always seal the avoidance long hole during the up and down sliding process to prevent aluminum liquid from leaking out.

[0056] The horizontal portion of the connecting rod 52 passes through the sealing plate 53, and the connecting rod 52 is fixedly connected to the sealing plate 53. The horizontal portion of the connecting rod 52 passes through the avoidance long hole, and the end of the horizontal portion of the connecting rod 52 is fixedly mounted with a mounting plate 54, on which a spring is arranged, and the other end of the spring is fixedly connected to the lower telescopic tube 40.

[0057] Therefore, when the aluminum liquid enters the lower telescopic tube 40, it can push the plug plate 51 downward, the connecting rod 52 drives the sealing slide plate 53 to descend, and the spring is stretched to realize the casting of the aluminum liquid. When the aluminum liquid approaches the upper end of the casting hole, the aluminum liquid in the casting hole will gradually cover the plug plate 51, thereby offsetting the downward thrust of the plug plate 51 when adding aluminum liquid. The spring pulls the plug plate 51 upward to reset it, thereby closing the hole in the center of the retaining ring 50, stopping the further addition of aluminum liquid into the casting hole, and avoiding the waste of aluminum liquid. If the aluminum liquid temperature is too low to continue casting, the aluminum liquid in the lower telescopic tube 40 can be recycled to the ladle and reused after heating.

[0058] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
