Description

Technical Field

[0001] This invention belongs to the field of casting technology, and in particular relates to a die-casting mold. Background Technology

[0002] In die casting production, contour robots are often used to automate tasks such as flash removal and mold surface trimming. However, existing contour robots are only compatible with multi-slider die casting molds, which presents significant limitations. Firstly, die casting molds typically have multiple sliders, and the die casting process involves harsh conditions such as high temperatures, metal dust, and strong equipment vibration. Long-term use can directly lead to positioning accuracy deviations in the contour robot, accelerated aging and failure of core components, and a persistently high equipment failure rate. Secondly, the deformation and flash formation position of products after multi-slider mold assembly are highly random. When the contour robot operates using a preset fixed motion trajectory, abnormal conditions such as tool over-cutting and rigid collision between the tool tip and the mold are prone to occur. Furthermore, when changing product types or modifying molds, the robot needs to undergo trajectory teaching and calibration again, resulting in a long debugging cycle and severely restricting production efficiency.

[0003] In the current industry landscape of high-speed production on die-casting lines, frequent switching between mold models and product specifications, and the co-production of multiple product categories, ensuring stable order delivery requires rapid response capabilities for routine mold maintenance and wear repair. Traditional manual mold repair methods are ill-suited to the complex working conditions of multi-slider die-casting molds.

[0004] Therefore, how to improve the mold repair efficiency of die-casting molds is a technical problem that urgently needs to be solved. Summary of the Invention

[0029] To address the existing technical problem of how to improve the mold repair efficiency of die-casting molds, this invention provides a die-casting mold, please refer to... Figure 1-4 , Figure 1 This is a schematic diagram of the overall structure of a die-casting mold provided in an embodiment of the present invention. Figure 2 This is an exploded structural diagram of a die-casting mold provided in an embodiment of the present invention. Figure 3 This is a schematic diagram of the structure of a quick-release locking assembly in the mold core locking state according to an embodiment of the present invention. Figure 4 This is a schematic diagram of a quick-release locking assembly in the open state of the die-casting mold, provided by an embodiment of the present invention. The die-casting mold includes a mold frame 10, a die core assembly 20, a slider assembly 30, and a quick-release locking assembly 40; the die core assembly 20 and the slider assembly 30 are disposed inside the mold frame 10, and the slider assembly 30 is arranged around the outside of the die core assembly 20; the outer wall of the die core assembly 20 is provided with a locking groove 21, and the quick-release locking assembly 40 is disposed on the mold frame 10. The quick-release locking assembly 40 includes a die core wrench 41, a transmission connecting rod 42, and a sliding buckle 43; the die core wrench 41 is connected to the sliding buckle 43 through the transmission connecting rod 42, and the sliding buckle 43 is engaged with the locking groove 21. The die-casting mold of the present invention uses a quick-release locking assembly, which allows the mold core to be locked and unlocked simply by moving the mold core wrench 41. This eliminates the traditional steps of disassembling and assembling bolts and pressure plates, effectively shortening the downtime for mold changeover and fault repair, and improving the maintenance efficiency and continuous production stability of the die-casting production line.

[0030] Specifically, in this embodiment, the die-casting mold comprises a mold frame 10, a mold core assembly 20, a slider assembly 30, and a quick-release locking assembly 40. The mold frame 10 serves as the supporting base for the entire mold, providing a mounting and positioning foundation for the internal forming components and locking components. The mold core assembly 20 and the slider assembly 30 are housed and assembled inside the mold frame 10. The slider assembly 30 is arranged around the outer periphery of the mold core assembly 20 and is used for lateral core-pulling during the die-casting process, meeting the forming and demolding requirements of undercut and convex structures in irregular die-cast products. A recessed locking groove 21 is integrally machined into the outer wall of the mold core assembly 20, serving as a locking and positioning slot. The quick-release locking assembly 40 is assembled from a mold core wrench 41, a transmission rod 42, and a sliding buckle 43 to form a linkage lever-type locking mechanism. The mold core wrench 41 and the sliding buckle 43 are hinged together by the transmission rod 42. The front end of the sliding buckle 43 can extend into the locking groove 21 on the side wall of the mold core assembly 20, forming an axial insertion and limiting fit, thereby locking and fixing the mold core assembly 20 in the cavity inside the mold frame 10. During the locking operation in die casting production, the operator moves the mold core wrench 41 towards the mold core assembly 20. The mold core wrench 41 swings with the transmission rod 42 as the fulcrum, and the axial thrust generated by the swing is directly transmitted to the sliding buckle 43 through the transmission rod 42. The end of the sliding buckle 43 is completely embedded in the locking groove 21. The rigid insertion and limiting of the sliding buckle 43 and the locking groove 21 restricts the displacement of the mold core assembly 20. During mold core maintenance, model change, and unlocking operations, when the mold core assembly 20 experiences cavity wear, chipping, or sticking requiring mold repair, or when changing product models necessitates mold core replacement, the mold core wrench 41 is pulled outwards in the opposite direction. This leverages the force to move the sliding buckle 43 away from the mold core assembly 20, completely disengaging the end of the sliding buckle 43 from the locking groove 21, thus releasing the lateral limiting constraint on the mold core assembly 20. At this point, without disassembling the main body of the mold frame 10 or removing numerous fixing plate bolts, the mold core assembly 20 can be directly pulled out from the mold frame 10 as a whole, completing the mold core maintenance. After maintenance, the mold core assembly is reset, and the mold core wrench 41 is pulled forward to re-lock and position it, allowing the mold to quickly return to production.

[0031] As a further preferred option, please refer to Figure 3 and Figure 4The sliding buckle 43 has a first receiving groove 431, and a limit pin 4311 is provided in the first receiving groove 431. The transmission connecting rod 42 passes through the mold core wrench 41 and the limit pin 4311 laterally. A locking bolt 433 is provided at the end of the sliding buckle 43 away from the mold core assembly 20. A first elastic element 432 is provided between the sliding buckle 43 and the locking bolt 433. One end of the first elastic element 432 abuts against the end face of the sliding buckle 43, and the other end of the first elastic element 432 abuts against the end face of the locking bolt 433. Specifically, in this embodiment of the invention, a first receiving groove 431 is formed in the middle of the sliding buckle 43. A limiting pin 4311 is fixedly assembled inside the first receiving groove 431. The transmission connecting rod 42 passes through the hinge hole of the mold core wrench 41 and the central through hole of the limiting pin 4311 in a transverse direction, thereby completing the hinge positioning of the mold core wrench 41 and the sliding buckle 43. The limiting pin 4311 constrains the radial offset of the transmission connecting rod 42, ensuring that the hinge point is stable and reliable. The locking bolt 433 is threadedly fixed to the side wall of the mold frame. A first elastic element 432 is fitted between the rear end face of the sliding buckle 43 and the bolt head of the locking bolt 433. The front end of the first elastic element 432 fits against the end face of the sliding buckle 43, and the rear end abuts against the end face of the locking bolt 433, forming a continuously pre-tightened support structure. In this invention, the limiting pin can stabilize the hinge structure and prevent the connecting rod from shaking and failing. In addition, the spring force assists in unlocking, making it easier to operate the wrench, and the overall structure has higher durability.

[0032] As a further preferred option, please refer to Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the structure of a first module frame provided in an embodiment of the present invention. Figure 6 This is a schematic diagram of a snap-fit ​​bushing provided in an embodiment of the present invention. A snap-fit ​​bushing 434 is fitted onto the outer wall of the sliding snap 43. A first groove 11 is formed on the inner sidewall of the mold frame 10 corresponding to the position of the snap-fit ​​bushing 434. The snap-fit ​​bushing 434 is embedded in the first groove 11, and the outer sidewall of the snap-fit ​​bushing 434 is clearance-fitted with the inner wall of the first groove 11. Specifically, in this embodiment of the present invention, the snap-fit ​​bushing 434 is interference-fitted onto the outer periphery of the sliding snap 43. The first groove 11 is formed on the inner sidewall of the mold frame 10 corresponding to the reciprocating movement path of the sliding snap 43. The snap-fit ​​bushing 434 is entirely embedded inside the first groove 11 for assembly. The outer wall of the snap-fit ​​bushing 434 and the groove wall of the first groove 11 are clearance-fitted to ensure that the sliding snap 43 can slide along the first groove 11. During the locking and unlocking reciprocating linear motion, the sliding buckle 43 slides directly against the wall of the first slide groove 11 via the buckle bushing 434, without direct frictional contact between the sliding buckle 43 body and the mold frame 10. This invention relies on the buckle bushing to achieve friction isolation, protecting the mold frame base slide groove from wear and extending the service life of the entire mold.

[0033] As a further preferred embodiment, please refer to 1 and Figure 2 The mold frame 10 includes a first mold frame 12 and a second mold frame 13, and the mold core assembly 20 includes a first mold core 22 and a second mold core 23. The first mold core 22 is assembled in the first mold frame 12, and the second mold core 23 is assembled in the second mold frame 13. The mold closing end faces of the first mold core 22 and the second mold core 23 are arranged facing each other. The mold frame is also provided with a mold locking buckle 14. The mating end walls of the first mold frame 12 and the second mold frame 13 are respectively provided with mounting holes. The mold locking buckle 14 is assembled into the mounting holes of the first mold frame 12 and the second mold frame 13 through a second fixing member 141. Specifically, in this embodiment of the invention, the mold frame 10 is assembled from a first mold frame 12 and a second mold frame 13. The mold core assembly 20 is divided into a first mold core 22 and a second mold core 23. The first mold core 22 is embedded and fixed inside the cavity of the first mold frame 12, and the second mold core 23 is embedded and fixed inside the cavity of the second mold frame 13. The forming and closing end faces of the first mold core 22 and the second mold core 23 are directly opposite each other. On the mating sidewalls where the first mold frame 12 and the second mold frame 13 fit together, the locking buckle 14 is locked and fixed at the mounting hole position of the two sets of mold frames by means of the second fixing member 141, realizing the quick snap-fit ​​positioning of the sides of the first mold frame 12 and the second mold frame 13.

[0034] As a further preferred option, please refer to Figure 1 and 4 The mold core wrench 41 is hingedly installed on the mating sidewalls of the first mold frame 12 and the second mold frame 13. The mold core wrench 41 is a bent-block structure with a hook bending portion 411. The transmission rod 42 passes laterally through the hook bending portion 411. Specifically, in this embodiment of the invention, the mold core wrenches 41 are arranged in pairs on the mating sidewalls of the first mold frame 12 and the second mold frame 13, and are respectively assembled at the locking points of the mold cores on both sides. The mold core wrench 41 is integrally formed as a bent-block structure, with the hook bending portion 411 integrally formed at the bending position. The transmission rod 42 passes laterally through and is fixed inside the hook bending portion 411, so that the mold core wrench 41 is hingedly installed with the transmission rod 42 as the rotation fulcrum.

[0035] As a further preferred option, please refer to Figure 2 and Figure 5The slider assembly 30 includes a slider body 31 and an inclined guide post 32. A second groove 15 is formed on the inner side of the first mold frame 12 corresponding to the position of the slider body 31, and the slider body 31 is embedded in the second groove 15. An inclined guide hole 311 is provided on the slider body 31, and the inclined guide post 32 passes through the inclined guide hole 311 of the slider body 31. Specifically, in this embodiment of the invention, the slider assembly 30 is composed of a slider body 31 and an inclined guide post 32. A second groove 15 is formed on the inner side wall of the first mold frame 12 corresponding to the movement path of the slider body 31. The slider body 31 is limited and embedded in the second groove 15, and can slide laterally along the second groove 15. An inclined guide hole 311 is machined through the slider body 31, and the inclined guide post 32 is inclinedly inserted into the inclined guide hole 311. One end of the inclined guide post is fixed to the side of the second mold frame 13 to realize the power transmission for mold opening and closing. The present invention achieves precise guidance and limitation of the slider body through the second groove.

[0036] As a further preferred option, please refer to Figures 7-8 , Figure 7 This is a schematic diagram of the structure of a die-casting cavity provided in an embodiment of the present invention. Figure 8 This is a schematic diagram of a flow channel structure provided in an embodiment of the present invention. The first mold core 22 and the second mold core 23 are fitted together at their closing end faces, forming a die-casting cavity 25. A flow channel 26 is provided on the closing end face of the first mold core 22, and a main flow channel 16 is provided on the mold frame 10. One end of the flow channel 26 is connected to the main flow channel 16, and the other end of the flow channel 26 is connected to the die-casting cavity 25. Specifically, in this embodiment of the present invention, the first mold core 22 and the second mold core 23 are tightly fitted together by their closing end faces, and their inner contours cooperate to form a closed die-casting cavity 25 for filling molten metal to form a casting. The flow channel 26 is machined and formed on the closing end face of the first mold core 22, and a through-flow main flow channel 16 is provided on the mold frame 10. One end of the flow channel 26 is connected to the main flow channel 16, and the other end is directly connected to the die-casting cavity 25, forming a complete pouring and feeding channel. During die casting, high-temperature molten metal is injected through the main channel 16 of the mold frame 10. The molten metal flows along the main channel 16 into the runner 26, and after being smoothly guided and distributed by the runner 26, it fills the die casting cavity 25. After the molten metal cools and solidifies, the casting is formed. After the mold is opened, the solidified material in the main channel and runner is removed along with the casting. The finished workpiece can then be obtained by cutting off the gate. This invention achieves stable molten metal feeding through the main channel and the runner on the mold core end face.

[0037] As a further preferred option, please refer to Figure 7The first mold core 22 has a positioning stop 221 on its mold-closing end face edge, and the second mold core 23 has a positioning groove 231 corresponding to the positioning stop 221 on its mold-closing end face edge. In the mold-closing state, the positioning stop 221 is fitted into the positioning groove 231. Specifically, in this embodiment of the invention, a boss-structured positioning stop 221 is integrally machined on the outer edge of the mold-closing end face of the first mold core 22, and a matching positioning groove 231 is formed on the corresponding mold-closing end face edge of the second mold core 23. When the mold completes the mold-closing action, the positioning stop 221 is fully embedded inside the positioning groove 231, achieving concave-convex alignment and locking of the parting surface contours of the first mold core 22 and the second mold core 23.

[0038] As a further preferred embodiment, cooling water channels 27 are formed inside the first mold core 22 and the second mold core 23. The cooling water channels 27 are through-hole structures, and the inlet and outlet 271 of the cooling water channels are located on the outer wall surface of the first mold core 22 and the second mold core 23. Specifically, in this embodiment of the invention, through-holes are machined inside the bodies of the first mold core 22 and the second mold core 23 to serve as cooling water channels 27. The cooling water channels are arranged around the periphery of the die-casting cavity 25, and the inlet and outlet 271 of the cooling water channels are opened on the exposed outer wall of the first mold core 22 and the second mold core 23 to facilitate the connection of external cooling water connectors.

[0039] As a further preferred option, please refer to Figure 2 The die-casting mold further includes a base plate 50, and a third fixing member 51 is provided between the base plate 50 and the second mold frame 13. The base plate 50 and the second mold frame 13 are fixedly connected by the third fixing member 51. A second elastic member 52 is also provided between the base plate 50 and the second mold frame 13. One end of the second elastic member 52 abuts against the base plate 50, and the other end of the second elastic member 52 abuts against the second mold frame 13. Specifically, in this embodiment of the invention, the third fixing member 51 provides a locking preload force to lock the base plate 50 and the second mold frame 13 into one piece, ensuring the overall structural strength of the mold back. During the die-casting production process, the vibrations generated by the mold closing impact and the molten metal impact are absorbed and buffered by the elastic deformation of the second elastic member 52, weakening the vibrations that are directly transmitted to the third fixing member 51. When the mold heats up and undergoes thermal expansion and contraction deformation, the second elastic member 52 adaptively compensates for the assembly gap through its own compression change, always maintaining a close and pressed state.
