Description

Technical Field

[0001] The present invention relates to the field of integrated die-casting technology, and in particular to an integrated die-casting mold and a production method for a new energy vehicle connection plate. Background Art

[0002] In short, the new energy vehicle connection plate is a key component used in new energy vehicles to achieve current connection and transmission between various components. Its structure is relatively complex, and it is usually produced using an integrated die-casting mold. After the existing die-casting mold is processed, the ejection mechanism is usually used to eject the workpiece from the mold, and the ejected workpiece falls off under the action of gravity and accumulates at the unloading place. However, in order to make the metal liquid flow smoother, the mold is usually set vertically. In order to complete the ejection and unloading, the ejector rod used to eject the workpiece has a long stroke, and then the workpiece is dropped from the mold by gravity. Since the bottom of the workpiece is blocked by the mold, the workpiece will inevitably collide with the mold during the falling process, which will cause scratches, deformation or even damage to the surface of the workpiece, affecting the quality of the workpiece.

[0003] To this end, Chinese patent application CN118385524A discloses an integrated die-casting mold for processing the oil pan of a new energy vehicle. By starting the second rotating rod, the circular motion of the curved rod is effectively driven, and a ninety-degree reciprocating swing motion is achieved through the coordinated action of the driving rod and the swing rod. During this process, the synchronous rotation of the driven wheel and the driving wheel ensures the stable rotation of the center rod, thereby driving the precise movement of the first rotating rod and the vacuum suction cup. Finally, the vacuum suction cup can use its automatic adsorption force to accurately place the die-cast finished product in the stacking trough, ensuring that the finished products are stacked neatly and avoiding mutual collision and wear.

[0004] However, this material extraction method relies on a transversely arranged runner. Although the transverse arrangement of the mold can improve layout flexibility and flow uniformity, the structure of the transversely arranged mold is more complex and it is difficult to ensure accuracy and stability. In addition, since the connecting plate structure of new energy vehicles is more complex and its cavity is deeper, the transversely arranged mold will cause the molten metal to be unable to stably fill the cavity, thereby affecting the processing quality of the workpiece. Summary of the invention

[0005] In view of the above problems, an integrated die-casting mold and production method for a new energy vehicle connecting plate are provided. The problem of how to quickly unload the vertically arranged mold while avoiding collision between the workpiece and the mold is solved through a frame, a flip mechanism and an ejection mechanism.

DETAILED DESCRIPTION

[0029] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] Reference Figure 1 and Figure 2: An integrated die-casting mold for a new energy vehicle connecting plate, including a frame 1, an upper mold 11 and a lower mold 12 are provided on the frame 1, and a lifting component 14 for driving the upper mold 11 to move in a vertical direction is provided on the frame 1, a support shaft 13 is provided on the frame 1, and the support shaft 13 is rotatably connected to the lower mold 12, and the lower mold 12 has a vertical state and a horizontal state. A flip mechanism 2 for controlling the rotation of the lower mold 12 is provided on the frame 1, and an ejection mechanism 3 for ejecting a workpiece is provided on the lower mold 12. In the working state, after the die-casting process of the workpiece is completed, the flip mechanism 2 drives the lower mold 12 to rotate from the vertical state to the horizontal state, and the ejection mechanism 3 ejects the workpiece.

[0031] The present invention realizes the function of controlling the conversion of the lower mold 12 between the vertical state and the horizontal state through the frame 1, the turning mechanism 2 and the ejection mechanism 3, so as to achieve the effect of maintaining the vertical distribution of the mold during processing and setting the lower mold 12 horizontally during blanking. It can not only ensure that the metal liquid can stably fill the cavity with a more complex structure during the mold processing, but also avoid the collision between the workpiece and the mold during blanking, and solves the problem of how to avoid the collision between the workpiece and the mold while quickly blanking the vertically arranged mold. The linear drive 141 is preferably a hydraulic cylinder, and the piston rod of the hydraulic cylinder is connected to the upper mold 11 through the connecting block 142. The frame 1 is arranged on a belt conveyor, the gate of the lower mold 12 is arranged on the side, the injection barrel for injecting molten metal is arranged on the side of the lower mold 12, and the injection barrel is connected with the gate on the lower mold 12 through a flexible gooseneck tube, and the injection barrel and the flexible gooseneck tube are both mature existing technologies and are not shown in the figure; in the working state, the operator first drives the connecting block 142 and the upper mold 11 downward through the linear drive 141, and tightly fits with the lower mold 12, and then performs die-casting processing through the cavity formed by the upper mold 11 and the lower mold 12, and then the upper mold 11 and the lower mold 12 are vertically connected. The arrangement allows the molten metal to maintain a smooth flow under the action of gravity, thereby filling the cavity and ensuring the die-casting quality of the workpiece. After the processing is completed, the upper mold 11 is controlled to rise by the lifting assembly 14, and after the distance between the upper mold 11 and the lower mold 12 reaches the specified range, the lower mold 12 is controlled to rotate around the axis of the support shaft 13 by the flip mechanism 2, thereby rotating the lower mold 12 from a vertical state to a horizontal state, and then the workpiece is ejected from the lower mold 12 by the ejection mechanism 3, and the ejected workpiece falls directly onto the conveyor belt of the belt conveyor, and the workpiece is moved to a specified position by the conveyor belt. Compared with the traditional die-casting mold, after the lower mold 12 is rotated to a horizontal state, the ejection mechanism 3 is used to cooperate with the workpiece, and no other material moving equipment is required, so that the workpiece can be removed conveniently and quickly, and because the mold is in a horizontal state when ejecting the material, it will not directly collide with the mold during the workpiece falling process.

[0032] Reference Figure 1 , Figure 3 and Figure 4 : The flipping mechanism 2 includes a gear ring 21 and a support rod 22. The gear ring 21 is sleeved on the support shaft 13. The support rod 22 is connected to the upper mold 11, and the gear ring 21 is provided on the support rod 22. In the working state, when the lifting assembly 14 controls the upper mold 11 to move upward, when the distance between the upper mold 11 and the lower mold 12 reaches the specified position, the rack 221 engages with the gear ring 21 and drives the gear ring 21 to rotate through the movement of the rack 221.

[0033] The present invention realizes the function of automatically driving the lower mold 12 to flip by lifting the upper mold 11 through the gear ring 21, the support rod 22 and the rack 221. In the working state, when the die-casting process of the workpiece is completed, the upper mold 11 is driven to move upward by the linear drive 141, and the upper mold 11 drives the rack 221 to move synchronously through the support rod 22, and when the rack 221 is engaged with the gear ring 21, there is enough gap between the upper mold 11 and the lower mold 12 for the lower mold 12 to flip, and then under the continuous movement of the upper mold 11, the rack 221 drives the gear ring 21 to rotate, and the gear ring 21 drives the support shaft 13 and the lower mold 12 to rotate, and after the lower mold 12 rotates 90°, the upper mold 1 1 completes the movement, and then the workpiece in the lower mold 12 is ejected by the ejection mechanism 3. As the workpiece is ejected, there is a certain gap between the workpiece and the lower mold 12, and the lower mold 12 falls off from the lower mold 12 under the action of gravity. Since the workpiece is ejected and the lower part of the workpiece is not blocked by the mold, the collision between the workpiece and the lower mold 12 can be avoided. After falling off, the workpiece will fall on the conveyor belt of the belt conveyor, and the material of the conveyor belt is usually rubber. Through the buffering of the conveyor belt, the workpiece can be prevented from being subjected to a large impact.

[0034] Reference Figure 1 , Figure 3 and Figure 4 : A guide bar 222 is provided on the support rod 22, a guide ring 23 is sleeved on the support shaft 13, a notch 231 is provided on the guide ring 23, and when the guide bar 222 slides with the notch 231 of the guide ring 23, the rotation of the guide ring 23 is restricted. In the working state, after the die-casting process of the workpiece is completed, the lifting assembly 14 drives the upper mold 11 to move upward, and during the upward movement, the guide bar 222 slides with the notch 231 of the guide ring 23, and when the guide bar 222 is separated from the notch 231 of the guide ring 23, the gear ring 21 engages with the rack 221.

[0035] The present invention realizes the function of limiting the self-rotation of the lower mold 12 under the action of gravity or other external forces through the guide bar 222 and the guide ring 23. In order to enable the lower mold 12 to rotate stably, it is necessary to have a sufficient gap between the upper mold 11 and the lower mold 12 before controlling the lower mold 12 to flip. For this purpose, the rack 221 will mesh with the gear ring 21 only when it rises to a sufficient distance. In order to prevent the lower mold 12 from swinging on its own when the gear ring 21 and the rack 221 are not meshed during the upward movement of the upper mold 11, resulting in the rack 221 and the gear ring 21 not being able to mesh accurately, a guide ring 23 is provided. When the upper mold 11 and the lower mold 12 are not separated, the guide bar 222 and the notch 231 on the guide ring 23 are slidably matched to limit the rotation of the guide ring 23. The guide ring 23 limits the rotation of the support shaft 13 to stabilize the lower mold 12, avoiding the lower mold 12 from swinging on its own when the gear ring 21 and the rack 221 are not meshed. The mold 12 swings on its own, and as the upper mold 11 moves upward, when the guide bar 222 separates from the notch 231, the rack 221 meshes with the gear ring 21, and then the gear ring 21 is driven to rotate by the rack 221. After the material is unloaded, the upper mold 11 is driven downward by the linear drive 141, and the upper mold 11 drives the support rod 22 and the rack 221 to move, and the gear ring 21 is driven to rotate in the opposite direction by the rack 221, and the lower mold 12 is controlled to reset. When the lower mold 12 rotates to a vertical state, the rack 221 separates from the gear ring 21, and the guide bar 222 on the support rod 22 slides with the notch 231 on the guide ring 23, thereby maintaining the vertical state of the lower mold 12 during the subsequent downward movement.

[0036] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 The ejection mechanism 3 includes a push rod 31, a push frame 32 and a pushing assembly 33. The push rod 31 is slidably installed on the lower mold 12. The push frame 32 is connected to the push rod 31. A first elastic member 321 is provided on the push frame 32. The two ends of the first elastic member 321 are respectively connected to the outer wall of the push frame 32 and the lower mold 12. The pushing assembly 33 is arranged on the frame 1, and the pushing assembly 33 is used to push the push frame 32 to move.

[0037] The present invention realizes the function of ejecting the workpiece from the lower mold 12 through the ejector 31, the push frame 32 and the pushing assembly 33. In the working state, when the lower mold 12 is in a vertical state, the pushing assembly 33 abuts against the side wall of the lower mold 12 and does not push the push frame 32. The push frame 32 has a tendency to move away from the lower mold 12 under the elastic force of the first elastic member 321, and then the push frame 32 is restricted by the push frame 32 to drive the ejector 31 to move, so that the ejector 31 is in a reset state. When the lower mold 12 is in a horizontal state, the pushing assembly 33 overcomes the elastic force of the first elastic member 321 to push the push frame 32 toward the lower mold 12, and the push frame 32 drives the ejector 31 to move, and then the workpiece is pushed out of the lower mold 12 through the ejector 31 to complete the unloading action.

[0038] Reference Figure 2 , Figure 5 and Figure 7 : The lower mold 12 is provided with a control mechanism 4 for controlling the movement of the push frame 32, and the control mechanism 4 includes a locking component 41 and a control component 42. The locking component 41 is used to limit the movement of the push frame 32, and the control component 42 is used to release the movement restriction of the push frame 32 by the locking component 41, and the push frame 32 is provided with a control block 322 that is transmission-connected with the control component 42. In the working state, when the pushing component 33 pushes the control block 322, the control block 322 drives the control component 42, and the control component 42 releases the movement restriction of the locking component 41 on the push frame 32, and the push frame 32 drives the push rod 31 to extend under the drive of the pushing component 33.

[0039] The present invention realizes the function of controlling the movement of the push frame 32 through the control block 322, the locking assembly 41 and the control assembly 42. If the workpiece is slowly pushed out by the push rod 31, the workpiece may still contact and rub with the lower mold 12 during the falling process. Although there will be no more intense collision with the lower mold 12, the friction may still cause the workpiece to wear and scratch the surface of the workpiece. For this reason, a control mechanism 4 is set. In the working state, when the lower mold 12 is in a vertical state, the pushing assembly 33 abuts against the side wall of the lower mold 12 and will not push the push frame 32. The push frame 32 has a tendency to move away from the lower mold 12 under the elastic force of the first elastic member 321, and then the push frame 32 limits the movement of the push rod 31, so that the push rod 31 is in a reset state. When the lower mold 12 rotates toward the horizontal state, the pushing component 33 continues to push the push frame 32, and the push frame 32 cannot move due to the fixing action of the locking component 41. As the lower mold 12 continues to rotate, when the pushing component 33 contacts the control block 322, it pushes the control block 322, and then drives the control component 42 through the control block 322. The control component 42 releases the movement restriction of the push frame 32 by the locking component 41, and then the pushing component 33 overcomes the elastic force of the first elastic member 321 to drive the push frame 32 to move, and the push frame 32 drives the push rod 31 to move, and then the workpiece is pushed out of the lower mold 12 through the push rod 31 to complete the unloading action, and the workpiece is quickly pushed out by releasing the movement restriction of the locking component 41 on the push frame 32, thereby avoiding the situation where the workpiece is too close to the lower mold 12 when falling off.

[0040] Reference Figure 5 and Figure 7-Figure 9 The locking assembly 41 includes a mounting seat 411, a locking block 412 and a second elastic member 413. The mounting seat 411 is arranged on the outer wall of the lower mold 12, and the locking block 412 is slidably installed on the mounting seat 411. The two ends of the second elastic member 413 are respectively connected to the mounting seat 411 and the locking block 412, and a locking groove 323 cooperating with the locking block 412 is opened on it.

[0041] The present invention realizes the function of limiting the rotation of the push frame 32 through the mounting seat 411, the locking block 412, the locking groove 323 and the second elastic member 413. When the control block 322 is not pushed, the locking block 412 is plugged and matched with the locking groove 323 on the push frame 32 under the elastic force of the second elastic member 413, and the movement of the push frame 32 is limited by the cooperation between the locking block 412 and the locking groove 323. When the control block 322 is pressed down by the pushing assembly 33, the control block 322 drives the control assembly 42, and the control assembly 42 overcomes the elastic force of the second elastic member 413 to drive the locking block 412 to move in a direction away from the locking groove 323, so that the locking block 412 is separated from the locking groove 323, and then the push frame 32 drives the push rod 31 to move under the driving action of the pushing assembly 33, and the push rod 31 is extended to drive the workpiece to separate from the lower mold 12.

[0042] Reference Figure 7-Figure 9 : The pushing assembly 33 includes an elastic telescopic rod 331, a bracket 332 and a roller 333. The elastic telescopic rod 331 is arranged on the frame 1, the bracket 332 is arranged at the end of the elastic telescopic rod 331 close to the lower mold 12, and the roller 333 is rotatably arranged on the bracket 332.

[0043] The present invention realizes the function of pushing the push frame 32 through the elastic telescopic rod 331, the bracket 332 and the roller 333. The elastic telescopic rod 331 is preferably a nitrogen spring, and the edge position of the push frame 32 is provided with a guide bar for guiding the rolling path of the roller 333. When the lower mold 12 rotates toward the horizontal state, the bracket 332 and the roller 333 continue to push the push frame 32 under the elastic force of the elastic telescopic rod 331, and the push frame 32 cannot move under the fixing action of the locking assembly 41. As the lower mold 12 continues to rotate, when the roller 333 contacts the control block 322, the control block 322 is pushed by the elastic force of the elastic telescopic rod 331, and then the control assembly 42 is driven through the control block 322. The control assembly 42 releases the movement restriction of the push frame 32 by the locking assembly 41, and then the pushing assembly 33 overcomes the elastic force of the first elastic member 321 to drive the push frame 32 to move, and the push frame 32 drives the push rod 31 to move, and then the workpiece is pushed out of the lower mold 12 through the push rod 31 to complete the blanking action, and the workpiece is quickly pushed out by releasing the movement restriction of the locking assembly 41 on the push frame 32, thereby avoiding the situation where the workpiece is too close to the lower mold 12 when falling off. By rolling the roller 333 along the push frame 32 , the push frame 32 can be pushed stably and the push frame 32 can be prevented from being worn by the push assembly 33 .

[0044] Reference Figure 5 and Figure 7-Figure 9 The control assembly 42 includes a slider 421, a push block and a third elastic member 423. The slider 421 is slidably mounted on the push frame 32. The push block is arranged at the end of the slider 421 and is located in the locking groove 323. The slider 421 is provided with an oblique guide groove 4211. The two ends of the third elastic member 423 are respectively connected to the slider 421 and the frame 1. In the working state, when the control block 322 is driven by the pushing assembly 33, the control block 322 squeezes the oblique guide groove 4211 of the slider 421, and overcomes the elastic force of the third elastic member 423 through the squeezing force to push the slider 421 and the push block toward the locking block 412.

[0045] The present invention realizes the function of releasing the movement restriction of the push frame 32 by the locking assembly 41 through the slider 421, the push block and the third elastic member 423. In the working state, as the lower mold 12 continues to rotate, when the roller 333 contacts the control block 322, the control block 322 is pushed by the elastic force of the elastic telescopic rod 331, and then the inclined guide groove 4211 on the slider 421 is squeezed by the control block 322, and the slider 421 and the push block are driven to move toward the locking block 412 by overcoming the elastic force of the third elastic member 423, and the third elastic member 423 is stretched, and then the locking block 412 is pushed by the push block, so that the locking block 412 is separated from the locking groove 323, and the movement restriction of the push frame 32 by the locking assembly 41 is released, and then the push assembly 33 overcomes the elastic force of the first elastic member 321 to drive the push frame 32 to move, and the push frame 32 drives the push rod 31 to move, and then the workpiece is pushed out of the lower mold 12 by the push rod 31, and the blanking action is completed.

[0046] Reference Figure 2 and Fig.10 : Both ends of the control block 322 are respectively provided with wing plates 3221, and the wing plates 3221 are provided with a fourth elastic member 3222, and both ends of the fourth elastic member 3222 are respectively connected to the wing plates 3221 and the push frame 32.

[0047] The present invention realizes the function of making the roller 333 push the control block 322 more smoothly through the wing plate 3221 and the fourth elastic member 3222, and improves the driving stability of the pushing assembly 33 on the control block 322. The wing plate 3221 is tilted relative to the control block 322. When the lower mold 12 is in a vertical state, the control block 322 and the wing plate 3221 are in an extended state under the elastic force of the fourth elastic member 3222, so that the control block 322 will not squeeze the oblique guide groove 4211 on the slider 421. When the lower mold 12 rotates toward the horizontal state, the roller 333 rolls toward the control block 322 through the wing plate 3221 on the control block 322, and overcomes the elastic force of the fourth elastic member 3222 through the elastic force of the elastic telescopic rod 331 to push the control block 322, and drives the control assembly 42 through the control block 322. The control assembly 42 releases the movement restriction of the locking assembly 41 on the push frame 32, and quickly pushes the push frame 32 to move through the roller 333.
