[0002] Die casting is a special casting method with little or no cutting that has developed rapidly in modern metal processing technology. It is a process in which molten magnesium alloy is filled into a mold under high speed and high pressure, and solidified into a casting under high pressure. This production process has the advantages of high production efficiency, simple process, high casting tolerance grade, good surface roughness, and high mechanical strength.

[0003] After searching, the existing patent (publication number: CN218855699UCN109128088A) discloses a new type of steering wheel skeleton die-casting mold, including a fixed mold, a fixed mold frame, a fixed mold core, a positioning hole, a round rod, a positioning block, a gate sleeve, a through hole, a movable mold core and a front core pulling structure; the top surface of the fixed mold frame is provided with a positioning hole; the movable mold frame is provided with a through hole; the fixed mold frame is provided with a round rod, and the round rod is connected with the through hole; the movable mold core is installed in the lower end surface of the movable mold frame; the fixed mold core is installed in the upper end surface of the fixed mold frame. In this steering wheel skeleton die-casting mold, a front core pulling structure and a rear core pulling structure are installed between the movable mold frame and the fixed mold frame, and the front core pulling structure is installed at the front end position of the movable mold frame, and the rear core pulling structure is installed at the rear end position of the lower mold frame of the fixed mold frame, so as to ensure that the steering wheel skeleton can be smoothly demolded from the steering wheel, reduce the sticking phenomenon of the die casting, and effectively improve the shift production. In the process of realizing the present invention, the inventor found that the prior art has the following problems:

[0004] The existing steering wheel frame die-casting mold lacks an effective mold locking mechanism during the die-casting process, which causes the mold to be easily displaced or misaligned during the die-casting process, resulting in low product accuracy and consistency. At the same time, the traditional manual or mechanical mold locking method of the existing die-casting mold has a slow opening and closing and locking speed for the mold, which is difficult for the staff to operate, reducing production efficiency;

[0005] Therefore, in view of the above problems, a steering wheel skeleton die-casting mold with oil cylinder clamping is proposed. Summary of the invention

[0006] In order to overcome the above defects of the prior art, the present invention provides a steering wheel skeleton die-casting mold with a cylinder clamping mold to solve the problems raised in the above background technology.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example 1

[0032] As attached Figures 1 to 8 The die-casting mold of a steering wheel skeleton with a cylinder clamping mold shown in the figure includes a guide plate 1. Guide columns 2 are arranged at the four corners of the guide plate 1. Two groups of guide plates 1 are arranged. The two groups of guide plates 1 enable the middle die-casting device 4 to be displaced along the guide columns 2. The guide plate 1 is made of metal material. An E12 skeleton 3 is arranged on one side of the guide plate 1. The E12 skeleton 3 is located on one side of the guide plate 1 and is closely connected to the guide plate 1. The E12 skeleton 3 is made of high-strength steel material to ensure its stability in the mold. Since the E12 skeleton 3 optimizes the structural layout of the mold, the mold replacement and adjustment are faster, the equipment downtime is reduced, and the continuous operation capability of the production line is improved.

[0033] ·A die-casting device 4 is arranged on one side of the E12 skeleton 3. The die-casting device 4 comprises a No. 1 plate 5, a No. 2 plate 6 and a No. 3 plate 7. The die-casting device 4 adopts a three-plate structure, which makes the mold more flexible and accurate during mold closing, die-casting, cooling and mold opening, and helps to improve production efficiency and product quality. The three-layer plate is made of high-strength tool steel material. The No. 1 plate 5 is used as a fixed plate and plays the role of a base in the die-casting mold. The No. 1 plate 5 bears the weight of the entire mold structure and provides a stable reference surface for other movable parts. The No. 1 plate 5 A fixed lock 8 is provided on one side of the fixed lock 8, and a second plate 6 is provided on one side of the fixed lock 8. The second plate 6 is located between the first plate 5 and the third plate 7, and plays a role of transmission and buffering. It cooperates with the first plate 5 and the third plate 7 during the die-casting process to realize the closing and opening of the mold. A third plate 7 is provided on one side of the second plate 6. The third plate 7 is the most active part of the entire mold and is driven by the cylinder core lock 9 to achieve locking and unlocking of the second plate 6, so that the mold remains stable during the die-casting process, thereby ensuring the quality and accuracy of the product.

[0034] Cylinder core-pulling locks 9 are provided on both sides of the third plate 7. The action of the cylinder core-pulling locks 9 is controlled by the control system and the cylinder 22 to ensure that each locking and unlocking action can be completed accurately and quickly. The core-pulling pin 24 is made of high-strength alloy steel. In the mold closing state, the cylinder 22 pushes the core-pulling pin 24 through the third plate 7 into the locking block plate 10 on the second plate 6 to achieve a firm connection between the second plate 6 and the third plate 7. When the mold is opened, the cylinder 22 contracts and the core-pulling pin 24 retreats to separate the plates. The position where the second plate 6 contacts the cylinder core-pulling lock 9 is provided with a locking block plate 10. The locking block plate 10 is made of high-strength tool steel. Specific holes are designed on the locking block plate 10 for receiving the core-pulling pin 24. These holes must be precisely machined to ensure accurate docking with the core-pulling pin 24. Through the design of the precisely matched locking block plate 10 and the core-pulling pin 24, high-stability locking of the mold is achieved, which helps to prevent accidental mold opening during the die-casting process and improves production safety.

[0035] Example 2

[0036] Based on Example 1, the solution in Example 1 is further detailed in combination with the following specific working method. Figures 1 to 9 As shown, see the following description for details:

[0037] As a preferred embodiment, a positioning rod 11 is provided on one side of plate No. 1 5, and a through hole 12 is provided on the outer wall of plate No. 1 5. There are several groups of through holes 12, and each group of through holes 12 is evenly arranged along the horizontal direction of plate No. 1 5. Furthermore, the main function of the positioning rod 11 is to ensure the precise alignment of plate No. 1 5 and plate No. 2 6 during mold closing. By using the positioning rod 11 to ensure precise alignment between the plates, defects caused by misalignment are greatly reduced, which not only improves the accuracy of the final casting, but also significantly improves the overall quality of the product. The through hole 12 is mainly used to reduce the weight of plate No. 1 5, provide a fixed anchor point and optimize the thermal balance of the mold.

[0038] As a preferred embodiment, a pouring port 13 is provided on one side of the No. 2 plate 6, and two groups of pouring ports 13 are provided, and the two groups of pouring ports 13 are evenly arranged in the horizontal direction of the No. 2 plate 6, and positioning piles 14 are provided at the four corners of one side of the No. 2 plate 6. Furthermore, the pouring port 13 ensures that the molten metal can fill the mold cavity evenly and quickly during the die-casting process, and a more uniform filling process also helps to reduce defects in the casting, such as cold shut and air holes, thereby improving the overall quality of the product. The positioning piles 14 are usually made of high-strength, wear-resistant materials. The main function of the positioning piles 14 is to ensure the precise alignment of the No. 2 plate 6 and the No. 3 plate 7 when the mold is closed.

[0039] As a preferred embodiment, displacement holes 15 are provided at the four corners of the third plate 7, a disk spoke 16 is provided at the center of one side of the outer wall of the third plate 7, and a disk ring 17 is provided on one side of the disk spoke 16. Furthermore, the displacement holes 15 are provided at the four corners of the third plate 7, and their main function is to provide the necessary mechanical positioning and movement guide for the third plate 7 during the opening and closing process of the mold. The displacement holes 15 allow the guide column 2 to pass through to ensure the precise alignment of the third plate 7 with other plate layers. The disk spoke 16 is usually made of high-strength alloy steel materials, which not only provide the necessary mechanical strength, but also can withstand repeated The design of the disc ring 17 helps to evenly distribute the stress generated during the casting process over the wide surface of the mold. This uniform distribution reduces local stress concentration, thereby reducing the risk of mold deformation or cracking. At the same time, the design of the disc spoke 16 and the disc ring 17 enhances the rigidity of the plate No. 3 7, allowing the mold to remain stable when subjected to high-pressure casting forces, reducing product defects caused by mold bending or deformation.

[0040] As a preferred embodiment, positioning holes 18 are provided in the middle of the disk spoke 16 and the disk ring 17. There are four groups of positioning holes 18, and the four groups of positioning holes 18 are evenly arranged along the circumferential direction of the disk spoke 16. Exhaust grooves 19 are provided on both sides of the disk spoke 16. Furthermore, there are four groups of positioning holes 18, which are evenly distributed in the circumferential direction of the disk spoke 16. The main function of these positioning holes 18 is to ensure the precise alignment of plate No. 3 7 with plate No. 1 5 and plate No. 2 6 during the mold closing process. Each positioning hole 18 is precision machined to ensure high-precision matching with the corresponding guide element, thereby ensuring the stability and consistency of the mold operation. The design of the exhaust groove 19 must take into account the principles of fluid dynamics to ensure that the gas can be discharged smoothly while avoiding the intrusion of molten metal. The function of the exhaust groove 19 is to remove the gas and heat generated during the casting process to prevent pores and internal defects in the casting.

[0041] As a preferred embodiment, overflow grooves 20 are provided on both sides of the disc ring 17, and an overflow port 21 is provided on the side of the overflow groove 20 close to the disc spoke 16. Furthermore, the material of the overflow groove 20 and the overflow port 21 is usually made of high-strength, wear-resistant alloy steel material. The overflow grooves 20 are designed on both sides of the disc ring 17. Its main function is to release excess molten metal during high-pressure casting, prevent mold overload and protect the mold structure. The position and size of the overflow port 21 are precisely calculated to ensure that the molten metal can be discharged smoothly without affecting the quality of the casting. By providing the overflow groove 20 and the overflow port 21, excess molten metal can be removed in time during the casting process to prevent the mold from being damaged due to overload, which improves the safety and operational stability of the mold. At the same time, this design enables the mold to work under higher pressure while maintaining safety and stability, which means that the length of the casting cycle can be increased or the casting speed can be increased, thereby improving production efficiency.

[0042] As a preferred embodiment, the cylinder core-pulling lock 9 includes a cylinder 22, a fixing frame 23 and a core-pulling pin 24. A fixing frame 23 is provided on one side of the cylinder 22, and a core-pulling pin 24 is provided inside the fixing frame 23. Furthermore, the fixing frame 23 is made of high-quality steel material. The action of the cylinder core-pulling lock 9 is controlled by a precise electro-hydraulic control system to ensure that each locking and unlocking action can be completed accurately and quickly. The design of the cylinder core-pulling lock 9 allows for rapid mold closing and opening, greatly reducing the time for mold replacement and adjustment, and improving the continuous operation capability of the production line.

[0043] As a preferred embodiment, when the die-casting device 4 is in mold closing position, the oil cylinders 22 on both sides of the third plate 7 drive the core pulling pin 24 to move, so that the core pulling pin 24 is combined with the locking block plate 10, so that the die-casting device 4 is locked. Furthermore, the oil cylinders 22 are located on both sides of the third plate 7, and each oil cylinder 22 is equipped with a core pulling pin 24. When the die-casting device 4 needs to be molded, the oil cylinder 22 receives the instruction and starts. The rapid response of the oil cylinder 22 enables the core pulling pin 24 to be quickly in place, thereby realizing rapid mold locking, which shortens the opening and closing time of the mold and improves production efficiency. At the same time, as the core pulling pins 24 move inward, they gradually enter the second After the core pulling pin 24 is fully inserted into the locking hole of the locking block plate 10 which is pre-set on the No. 6 plate, the No. 3 plate 7 and the No. 2 plate 6 are accurately locked. At this time, the entire mold is in a tightly closed state. The precise cooperation between the core pulling pin 24 driven by the cylinder 22 and the locking block plate 10 ensures the accurate alignment and tight combination between the No. 2 plate 6 and the No. 3 plate 7, which greatly reduces the dimensional deviation of the casting and improves the consistency of the product. The rapid response of the cylinder 22 enables the core pulling pin 24 to be quickly put into place, thereby realizing rapid mold locking, which shortens the opening and closing time of the mold and improves production efficiency.

[0044] As a preferred embodiment, when the die-casting device 4 stops during mold opening, the No. 1 plate 5 moves away from the No. 2 plate 6 along the positioning rod 11 driven by the guide plate 1, and the cylinder core lock 9 remains stationary, so that the combination of the No. 2 plate 6 and the No. 3 plate 7 remains stable. Furthermore, in the mold opening stage of the die-casting cycle, the No. 1 plate 5 begins to move along the positioning rod 11, and this action is controlled by the guide plate 1 to ensure that the translation of the plate is linear and precise. The positioning rod 11 not only provides a moving path, but also ensures that the relative position of the No. 1 plate 5 and the No. 2 plate 6 is always consistent to avoid misalignment. This design ensures that in the partially open mold state, the connection between the No. 2 plate 6 and the No. 3 plate 7 will not loosen, maintain the partial fixed state of the mold, and can perform partial adjustment of the mold or removal of the casting without complete mold opening, thereby increasing the flexibility of production operations. At the same time, this mechanism facilitates the rapid resolution of small problems in production without completely stopping the machine and opening the mold, saving time and improving efficiency.

[0045] As a preferred embodiment, after the die-casting device 4 completes the mold opening, the core pulling pin 24 is separated from the locking block plate 10, and both the No. 2 plate 6 and the No. 1 plate 5 are displaced along the outer wall of the guide column 2 through the guide plate 1 to open the mold. Furthermore, this design achieves a rapid mold opening mechanism through the cylinder core pulling lock 9, reduces the residence time of the mold, and allows the production line to operate continuously and efficiently, which improves overall production efficiency and shortens product delivery cycle. At the same time, reducing downtime also reduces the time wasted waiting for the mold to cool, further improving production continuity, and a stable mold opening process ensures the consistency and integrity of the casting when it leaves the mold, reducing internal stress and surface defects caused by mold misalignment or uneven cooling.

[0046] The working process of the present invention is as follows: first, the control system starts the mold closing program, and the guide plate 1 moves along the predetermined trajectory through the precisely guided guide column 2 to ensure that the No. 1 plate 5, the No. 2 plate 6 and the No. 3 plate 7 are accurately aligned. As the mold plate moves, the oil cylinders 22 located on both sides of the No. 3 plate 7 are activated to push the core pulling pin 24 to move inward, that is, to move forward in the direction of the mold center line. The core pulling pin 24 continues to move forward and finally enters the hole of the preset locking block plate 10 on the No. 2 plate 6 to achieve tight locking of the No. 2 plate 6 and the No. 3 plate 7. At this time, the mold is completely closed and ready for die casting. Once the mold is completely closed and locked, the molten metal liquid is injected into the mold cavity of the die casting device 4 through the pouring port 13 on the No. 2 plate 6. The metal liquid is The mold cavity cools and solidifies to form a predetermined shape of the steering wheel skeleton. This stage needs to be maintained for a certain period of time to ensure the integrity of the casting structure. After casting is completed, the control system first instructs the cylinder 22 to partially contract, and the core pulling pin 24 partially withdraws from the locking block plate 10, but not completely, to maintain the partial connection between the No. 2 plate 6 and the No. 3 plate 7. Subsequently, the cylinder 22 continues to contract, and the core pulling pin 24 completely withdraws from the locking block plate 10. At the same time, the guide plate 1 drives the No. 1 plate 5 and the No. 2 plate 6 to move along the outer wall of the guide column 2 to achieve full opening of the mold. Finally, the operator or automatic manipulator removes the solidified casting from the mold to complete a die-casting cycle. The above is the working principle of the steering wheel skeleton die-casting mold with cylinder locking.
