Description

Technical Field

[0001] The invention relates to the technical field of automobile component casting, in particular to a casting device for automobile metal components. Background Art

[0002] Die casting is a precision casting method that uses high pressure to force molten metal into a complex metal mold. The casting equipment and molds are expensive, so the die casting process is generally used to mass-produce a large number of products. At present, based on the needs of environmental protection and energy conservation, automobile lightweighting has become a trend in the development of the world's automobile industry, especially in new energy vehicles, reducing the assembly weight of new energy vehicles as much as possible, thereby improving the power performance of new energy vehicles. With the development and improvement of material technology and casting forming technology, in order to achieve lightweight new energy vehicles, more and more automobile manufacturers use aluminum alloy castings as components of new energy vehicles.

[0003] During the use of the existing casting device for metal parts of new energy vehicles, after the casting of the metal parts is completed, the metal parts are usually ejected from the mold by the ejection structure set inside the casting device, and then the ejected metal parts are grabbed and placed manually or by a mechanical arm, thereby completing the material collection process of the metal parts. When the metal parts are grabbed and placed manually, since the casting device will generate a high temperature during the casting process, the operator is very likely to get fatigued after working for a long time, which can easily cause the operator to be injured during the work process and reduce work efficiency. Therefore, in the existing casting process, most of the time, a mechanical arm is used to replace manual grasping of metal parts to ensure the safety and work efficiency during work.

[0004] During the use of the robotic arm, in order to control the robotic arm to grab the metal parts, it is necessary to set multiple working parameters to achieve the fixed action of the robotic arm, so as to complete the grabbing action of the metal parts. However, during the action of the robotic arm, the robotic arm cannot respond to sudden situations, that is, the robotic arm cannot respond accordingly according to the action of the ejection structure, resulting in poor coordination between the robotic arm and the ejection structure, which easily affects the material removal effect after the metal parts are cast. Summary of the invention

An annular slot 20 is provided on the side wall of the movable seat 7, and the guide ring 19 is movably inserted in the annular slot 20. An abutment baffle 18 is fixed on the inner wall of one end of the rotating sleeve 13 close to the guide ring 19, and the abutment baffle 18 is located inside the mounting notch 12. A supporting spring 14 is sleeved on the transmission rod 101, and the supporting spring 14 is located on the side of the rotating sleeve 13 away from the guide ring 19, and one end of the supporting spring 14 abuts against the rotating sleeve 13, and the other end abuts against the groove wall of the mounting groove 9.

[0043] Reference Figure 4 and Figure 5 A hollow rod 15 is fixedly mounted on the rotating sleeve 13. One end of the hollow rod 15 away from the rotating sleeve 13 is fixedly connected to a suction cup 16. A piston assembly 17 is provided in both the hollow rod 15 and the rotating sleeve 13. The piston assembly 17 includes a piston body 171, a piston rod 172 and a transmission gear 173. The piston body 171 is movably placed in the hollow rod 15 and is tightly fitted against the inner wall of the hollow rod 15. One end of the piston rod 172 is fixedly connected to the piston body 171, and the other end passes through the rotating sleeve 13 and extends to the outside of the rotating sleeve 13. The piston rod 172 has an external thread on its circumference. The transmission gear 173 is rotatably mounted inside the rotating sleeve 13 and sleeved on the circumference of the piston rod 172. The transmission gear 173 is meshed with the transmission rack 102 and is threadedly connected to the piston rod 172.

[0044] Reference Figure 4 and Figure 5When the output shaft of the electric cylinder 81 extends out, the transmission rod 101 moves in a direction away from the electric cylinder 81 driven by the connecting rod 82, and at the same time, the insertion rod 103 slides relative to the first arc groove 111, so that the transmission rod 101 rotates counterclockwise while moving horizontally, and under the supporting action of the supporting spring 14, the rotating sleeve 13 and the hollow rod 15 are driven to rotate counterclockwise, so that the rotated hollow rod 15 is arranged in the vertical direction, so that the suction cup 16 fits the surface of the metal part.

[0045] At the same time, the transmission gear 173 rotates under the drive of the transmission rack 102, thereby driving the piston rod 172 and the piston to move away from the suction cup 16, thereby generating negative pressure inside the hollow column, which helps the suction cup 16 to generate suction and absorb and grasp the metal parts.

[0046] Reference Figure 4 and Figure 5 When the transmission rod 101 continues to move, the insertion rod 103 will slide along the first arc groove 111 to the inside of the straight groove 112, and at the same time, the abutment baffle 18 will abut against the groove wall of the installation groove 9, so that the transmission rod 101 drives the rotating sleeve 13 and the hollow rod 15 to move in the direction away from the movable mold 3, which helps to completely bring the metal parts adsorbed and grasped by the suction cup 16 out of the movable mold 3, thereby improving the material removal effect after the metal parts are cast.

[0047] Reference Figure 4 and Figure 5 When the transmission rod 101 continues to move, the insertion rod 103 will enter the second arc groove 113 along the straight groove 112, thereby driving the rotating sleeve 13 and the hollow rod 15 to rotate clockwise, and then the rotating hollow rod 15 drives the metal part to deviate from the position between the movable mold 3 and the fixed mold 4.

[0048] Reference Figure 4 and Figure 5 The output shaft of the electric cylinder 81 contracts, and drives the transmission rod 101 to move toward the electric cylinder 81 through the connecting rod 82, so that the transmission gear 173 rotates in the opposite direction under the drive of the transmission rack 102, driving the piston rod 172 and the piston to move toward the direction close to the suction cup 16, thereby causing the negative pressure inside the hollow column to gradually disappear, which helps to release the suction cup 16 from adsorption and grasping of the metal part, thereby placing the metal part.

[0049] The implementation principle of the embodiment of the present application is as follows: when casting a metal part, the output end of the pusher 2 extends to push the movable mold 3 and the fixed mold 4 to engage, so that a casting cavity is formed between the engaged movable mold 3 and the fixed mold 4. At the same time, the molten metal inside the furnace 21 enters the injection cylinder 22 through the introduction channel 25, and the output shaft of the hydraulic cylinder 23 extends to drive the piston to move downward, and the molten metal inside the injection cylinder 22 is squeezed while the introduction channel 25 is blocked, so that the squeezed molten metal passes through the injection channel 26 and the injection pipe 27 in turn, enters the casting cavity between the movable mold 3 and the fixed mold 4 and fills the casting cavity, and the casting of the metal part is completed after cooling.

[0050] After the metal component is cast, the output end of the pusher 2 contracts, so that the movable mold 3 is separated from the fixed mold 4, and the formed metal component is located inside the movable mold 3. The output shaft of the electric cylinder 81 extends, driving the connecting rod 82 and the connecting plate 83 to move toward the movable mold 3, so that the ejector 84 moves synchronously inside the movable mold 3, which helps to eject the metal component from the movable mold 3.

[0051] When the output shaft of the electric cylinder 81 extends, the transmission rod 101 moves away from the electric cylinder 81 under the drive of the connecting rod 82, and the insertion rod 103 slides relative to the first arc groove 111, so that the transmission rod 101 rotates counterclockwise while moving horizontally, and under the supporting action of the supporting spring 14, the rotating sleeve 13 and the hollow rod 15 rotate counterclockwise, so that the rotated hollow rod 15 is arranged in the vertical direction, so that the suction cup 16 fits the surface of the metal part. At the same time, the transmission gear 173 rotates under the drive of the transmission rack 102, thereby driving the piston rod 172 and the piston to move away from the suction cup 16, so that negative pressure is generated inside the hollow column, which helps the suction cup 16 to generate suction and absorb and grab the metal part.

[0052] When the transmission rod 101 continues to move, the insertion rod 103 will slide along the first arc groove 111 to the inside of the straight groove 112, and at the same time, the abutment baffle 18 will abut against the groove wall of the installation groove 9, so that the transmission rod 101 drives the rotating sleeve 13 and the hollow rod 15 to move in the direction away from the movable mold 3, which helps to completely bring the metal parts adsorbed and grasped by the suction cup 16 out of the movable mold 3, thereby improving the material removal effect after the casting of the metal parts is completed.

[0053] When the transmission rod 101 continues to move, the insertion rod 103 will enter the second arc groove 113 along the straight groove 112, thereby driving the rotating sleeve 13 and the hollow rod 15 to rotate clockwise, and then the rotating hollow rod 15 drives the metal part to deviate from the position between the movable mold 3 and the fixed mold 4.

[0054] The output shaft of the electric cylinder 81 contracts, and drives the transmission rod 101 to move toward the electric cylinder 81 through the connecting rod 82, so that the transmission gear 173 rotates in the opposite direction under the drive of the transmission rack 102, driving the piston rod 172 and the piston to move toward the direction close to the suction cup 16, thereby causing the negative pressure inside the hollow column to gradually disappear, which helps to release the suction cup 16 from adsorption and gripping of the metal part, thereby placing the metal part.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
