Description
Technical Field
[0001] This utility model relates to the field of die-casting mold technology, and in particular to a shaping drive device for automotive aluminum shell die-casting molds. Background Technology
[0002] In aluminum die-casting molds, current fixed-drive structures are relatively simple in design and cannot effectively withstand the enormous pressure and impact generated during die-casting. Due to insufficient structural stability, the drive structure is prone to loosening and deformation under frequent die-casting operations. The direct consequence of insufficient stability is a reduction in the quality of the formed aluminum shell. On the one hand, an unstable drive structure makes it difficult to precisely control the opening and closing of the die-casting mold, resulting in significant deviations in the dimensional accuracy of the aluminum shell during the forming process. On the other hand, instability during the die-casting process causes uneven stress on various parts of the aluminum shell, easily leading to defects such as cracks and pinholes on the surface, severely affecting the appearance quality and mechanical properties of the aluminum shell. This not only increases the defect rate and production costs but also limits the application of aluminum shells in fields with high quality requirements. Utility Model Content

[0024] like Figures 1-4As shown, in one embodiment of this utility model, a shaping drive device for automotive aluminum shell die-casting molds is disclosed, comprising a mold body 1, a forming component 2, a drive component 3, a sliding component 4, and a shaping component 5. The forming component 2 is disposed within the mold body 1, the sliding component 4 is disposed on the mold body 1 and located on one side of the forming component 2, and the shaping component 5 is slidably disposed on the sliding component 4 and connected to the drive end of the drive component 3, sliding on the sliding component 4 and reciprocating to the forming component 2 under the action of the drive component 3. The drive component 3 comprises a drive mounting frame 31, a drive module 32, a limiting module 33, and a drive connecting rod 34. The drive mounting frame 31 is disposed on one side of the mold body 1, the drive module 32 is disposed on the drive mounting frame 31 and is used to drive the drive connecting rod 34 to move, the limiting module 33 is used to limit the movement of the drive connecting rod 34, and one end of the drive connecting rod 34 is connected to the shaping component 5 so that the shaping component 5 is driven to reciprocate to the forming component 2 under the action of the drive module 32. This embodiment achieves efficient shaping operation of the die-casting mold in the manufacturing process of automotive aluminum shells through the coordinated design of the forming component 2, driving component 3, sliding component 4, and shaping component 5. In the driving component 3, the driving module 32 is mounted on the driving mounting bracket 31, precisely driving the driving linkage 34 to provide a stable and controllable power source for the reciprocating motion of the shaping component 5. By precisely controlling the driving module 32, the motion parameters of the driving linkage 34 can be flexibly adjusted according to actual production needs, ensuring that the shaping component 5 accurately reciprocates to the forming component 2, greatly improving the accuracy and stability of the shaping stage in the die-casting process of the aluminum shell.

The sliding component 4 allows the shaping component 5 to slide smoothly on it, reducing friction during movement, improving the operating efficiency of the device, and also helping to reduce energy consumption. The shaping component 5 reciprocates on the sliding component 4 under the action of the driving component 3, which can shape the aluminum shell in the die-casting process in a timely manner, effectively improving the forming quality of the aluminum shell and reducing product defects caused by untimely or inaccurate shaping.
[0025] The mold body 1 includes an upper mold base 11 and a lower mold base 12, with a forming cavity 13 provided between the upper mold base 11 and the lower mold base 12. The forming component 2 is disposed within the forming cavity 13. Specifically, the forming component 2 includes a forming upper plate 21, a forming lower plate 22, and a die-casting cavity 23. The forming upper plate 21 and the forming lower plate 22 are mated to form the die-casting cavity 23. A shaping opening is provided on one side of the forming cavity 13, and the shaping component 5 is disposed at the shaping opening. In this embodiment, the arrangement of the upper mold base 11, the lower mold base 12, and the forming cavity 13 between them in the mold body 1 provides a stable and reliable spatial structure for the entire die-casting process, ensuring that the forming component 2 can complete the aluminum shell die-casting operation in a specific area, thus guaranteeing the overall structural stability of the mold and the operability of the die-casting process. In forming component 2, the upper forming plate 21 and the lower forming plate 22 mate to form a die-casting cavity 23, precisely defining the space for aluminum liquid filling and forming. This allows for efficient and accurate molding of complex shapes and high-precision dimensions that meet the design requirements of automotive aluminum shells, greatly improving the quality and precision of aluminum shell forming. Meanwhile, the shaping component 5 is located at the shaping opening on one side of the forming cavity 13. After die casting, it can quickly shape the aluminum shell, effectively avoiding deformation during the cooling and shrinkage process, further improving the shape stability and dimensional accuracy of the aluminum shell. This meets the stringent standards for product quality and performance in automotive parts.
[0026] The shaping component 5 includes a shaping movable plate 51, on which a shaping groove 52 is provided facing the die-casting cavity 23. The shaping movable plate 51, the upper forming plate 21, and the lower forming plate 22 are arranged in a triangular distribution. In this embodiment, the shaping movable plate 51 and the shaping groove 52 thereon can precisely guide and restrict the flow and shaping of liquid aluminum during the die-casting process. The triangular distribution design enables the shaping movable plate 51, the upper forming plate 21, and the lower forming plate 22 to form a stable and efficient collaborative working mode. When die-casting begins, liquid aluminum fills the die-casting cavity 23, and the shaping groove 52 can shape specific parts of the aluminum shell, ensuring the dimensional accuracy and surface quality of that part, and reducing forming defects caused by the free flow of aluminum. At the same time, the triangular distribution enhances the stability of the entire mold structure, effectively disperses the huge pressure generated during the die-casting process, avoids deformation or damage caused by local stress concentration in the mold, and extends the service life of the mold.
[0027] The drive mounting frame 31 includes two fixed side plates 311 and a mounting beam 312. The mounting beam 312 is mounted between the two fixed side plates 311. The fixed side plates 311 are mounted on the mold body 1 and have mounting ramps. The mounting beam 312 is mounted on the mounting ramps. The drive module 32 is mounted on the mounting beam 312. In this embodiment, the fixed side plates 311 are mounted on the mold body 1 and have mounting ramps, while the mounting beam 312 is mounted between the two fixed side plates 311 and on the mounting ramps. This structural design enhances the overall stability of the drive mounting frame 31. The mounting ramps can effectively disperse the stress generated by the drive module 32 during operation, avoiding stress concentration that could damage the mold body 1 and extending the mold's service life. By mounting the drive module 32 on the mounting beam 312, the drive module 32 is precisely positioned and installed on the mold, ensuring that it can play a precise role in the die casting process, improving the accuracy and reliability of the drive action, thereby improving the forming precision and quality of automotive aluminum shell die casting.
[0028] The drive module 32 is a drive cylinder or hydraulic cylinder, and the drive connecting rod 34 is movably disposed within the cylinder body of the drive module 32. The limiting module 33 includes a limiting fixing block 331 disposed on the drive module 32, a limiting rod 332 disposed on the limiting fixing block 331, and a limiting baffle 333 disposed on the drive connecting rod 34. The limiting rod 332 is used to limit the movement of the limiting baffle 333. In this embodiment, the drive cylinder or hydraulic cylinder serves as a power source, possessing strong and stable driving force, which can precisely control the movement of the drive connecting rod 34, ensuring that the force and speed of the die-casting mold during key actions such as mold opening and closing meet the process requirements, effectively improving the stability and reliability of die-casting production. The setting of the limiting module 33 further optimizes the running accuracy of the mold. The limiting rod 332 limits the movement of the limiting baffle 333, which can accurately define the movement range of the drive connecting rod 34, preventing damage to mold components due to excessive movement, and ensuring that each component of the mold operates safely and orderly within the specified stroke.
[0029] The sliding assembly 4 includes sliding guide plates 41 disposed on both sides of the drive link 34 and a slider 42 disposed between the two sliding guide plates 41. The slider 42 is slidably disposed on the sliding guide plates 41, and the shaping assembly 5 is disposed on the slider 42 and slides with the slider 42. A sliding guide groove 411 is provided on the sliding guide plate 41, which is parallel to the axial direction of the drive link 34. The slider 42 is slidably disposed on the sliding guide groove 411. Specifically, the sliding guide plate 41 is disposed on the mold body 1, and a positioning step 412 is provided on one side of the sliding guide plate 41, which is parallel to one side of the drive mounting bracket 31. In this embodiment, the slider 42 can slide smoothly along a predetermined path, effectively reducing offset and wobbling during the sliding process, ensuring the positional accuracy of the shaping assembly 5 when it slides with the slider 42, thereby improving the accuracy and stability of the die-casting process of automotive aluminum shells. The cooperation between the slider 42 and the sliding guide groove 411 greatly improves the smoothness of the entire mechanism's movement. This not only reduces wear between components and extends the service life of the mold, but also makes the die-casting process more efficient. The sliding guide plate 41 is mounted on the mold body 1, and the positioning step 412 is parallel to the drive mounting bracket 31, further enhancing the stability of the mold structure. This allows it to better withstand the enormous pressure and impact generated during the die-casting process, ensuring the mold can still operate normally under complex working conditions.
