[0002] Automotive casting molds are a key process equipment used to manufacture automotive parts. They produce parts with complex structures, such as engine blocks or suspension components, by injecting molten metal into the mold and cooling it to form. Since molds are usually large and heavy, they need to be transferred using lifting equipment during replacement, assembly or transportation. During the lifting process, the mold will shake due to uneven gravity distribution or external force, which will not only increase the difficulty of operation, but may also cause positioning errors or damage to the mold. Therefore, the mold usually needs to be equipped with a dedicated positioning mechanism to ensure that the position of the mold can be effectively fixed during lifting or installation. The positioning mechanism stabilizes the mold by limiting, locking or guiding, reduces the offset caused by shaking, ensures accurate mold installation, and improves the safety and efficiency of lifting operations.

[0020] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0021] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the present invention should be understood by people with ordinary skills in the field to which the present invention belongs. The "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components.

"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0022] like Figures 1 to 10As shown, a quick positioning mechanism for a car casting mold includes a positioner body 3 placed on a workbench 1, the positioner body 3 is used to quickly position the mold body 2, one end of the positioner body 3 is fixedly connected to a pull rod 4, the other end of the positioner body 3 is rotatably mounted with a positioning head 5, and the middle part of the end of the positioning head 5 away from the positioner body 3 is provided with an extension plate 8; a pre-contact component, the pre-contact component is arranged on one side of the extension plate 8, and the pre-contact component is used to perform pre-contact positioning with the mold body 2; two sets of clamping components, the two sets of clamping components include two first clamping plates 1 0, and two second clamping plates 23 adapted to the first clamping plates 10, the two first clamping plates 10 are arranged on the extension plate 8, and the two second clamping plates 23 are respectively arranged on the upper and lower sides of the pre-contact component, and the clamping component is used to clamp and fix the pre-contact component after the mold body 2 is positioned, so as to facilitate the removal of the positioning mechanism, and a universal ball 6 is arranged between the locator body 3 and the positioning head 5, and a ball head seat 7 is arranged on the opposite surface of the locator body 3 and the positioning head 5 to limit the universal ball 6; first, place the locator body 3 on the workbench 1 , so that the pre-contact component at one end of the locator body 3 initially contacts the workbench 1. At this time, the pre-contact component is in the initial position, causing the free end of the locator head 5 to be slightly raised relative to the locator body 3, and the pull rod 4 is at a certain angle to the locator body 3. When the mold body 2 gradually approaches the locator body 3, the bottom surface of the mold body 2 begins to contact and push the pre-contact component. As the mold moves, the pre-contact component gradually adjusts its height, so that the free end of the locator head 5 moves downward until it is parallel to the locator body 3. At the same time, the pull rod 4 is connected to the locator body 3 through its rotating mechanism. One side maintains synchronous adjustment and is finally in a parallel state. After the height of the mold is consistent with that of the positioning head 5, the locking assembly starts to work. The two first locking plates 10 on the extension plate 8 are automatically aligned and locked with the second locking plates 23 on the upper and lower sides of the pre-contact assembly. This process ensures that the mold remains in a precise fixed state under the action of the locator to prevent movement or deviation. At this time, the operator gently applies force through the pull rod 4 to pull the locator out from under the mold. Since the locking assembly has locked the pre-contact assembly, the action of pulling out the locator will not affect the positioning state of the mold.

[0023] like Figures 4 to 8As shown, the pre-contact assembly includes a fixed column 11 fixedly mounted on one side of the extension plate 8, a rotating plate 12 is sleeved on one side of the fixed column 11, a torsion spring is provided at the sleeve position of the rotating plate 12 and the fixed column 11, a first connecting rod 13 and a second connecting rod 14 are rotatably mounted on both sides of the rotating plate 12, a first auxiliary positioning block 15 is rotatably mounted on the other end of the first connecting rod 13, and a second auxiliary positioning block 16 is rotatably mounted on the other end of the second connecting rod 14, the first auxiliary positioning block 15 is arranged above the workbench 1, and the second auxiliary positioning block 16 is used to make pre-contact with the positioner body 3, and a first auxiliary positioning block 15 is provided on one side. The following block 17, a second following block 18 is arranged on one side of the second auxiliary positioning block 16, the first auxiliary positioning block 15 is arranged opposite to the second auxiliary positioning block 16, the first following block 17 is arranged opposite to the second following block 18, when the second auxiliary positioning block 16 is close to the first auxiliary positioning block 15, the gap between the first following block 17 and the second following block 18 is adapted to the thickness of the extension plate 8, and a telescopic rod 33 is arranged between the first auxiliary positioning block 15 and the second auxiliary positioning block 16 for positioning; the positioner body 3 is placed on the workbench 1, so that one side of the fixed column 11 of the extension plate 8 faces the mold body 2, and in the initial state, rotate The plate 12 is sleeved on the fixed column 11 and is acted upon by the torsion spring to maintain its initial reset position. At this time, the first auxiliary positioning block 15 is located above the workbench 1, and the second auxiliary positioning block 16 is close to the positioner body 3. As the mold body 2 approaches the positioner, the bottom surface of the mold gradually contacts and pushes the second auxiliary positioning block 16, so that the rotating plate 12 rotates around the fixed column 11. The first connecting rod 13 and the second connecting rod 14 are driven by the rotating plate 12 to close inward, and the first auxiliary positioning block 15 and the second auxiliary positioning block 16 are gradually brought together. When the distance between the auxiliary positioning blocks is reduced to be equal to the thickness of the extension plate 8, the first following block 17 and the second following block 18 are moved to the same position as the extension plate 8. A gap matching the thickness of the extension plate 8 is formed between the two follower blocks 18 to ensure that the extension plate 8 is in the correct position. At the same time, the telescopic rod 33 maintains a fixed distance between the auxiliary positioning blocks to prevent the auxiliary positioning blocks from being too close or loose, further ensuring the positioning accuracy of the mold. When the mold reaches the final positioning position, the positioning head 5 contacts and remains parallel to the mold body 2, and the first clamping plate 10 and the second clamping plate 23 begin to align and clamp to fix the mold. Subsequently, the operator gently applies force through the pull rod 4 to pull out the locator, contact the limit of the clamping assembly, and the auxiliary positioning block returns to its initial position under the action of the torsion spring, and the entire positioning process is completed.

[0024] like Figure 5 , Figure 7 , Figure 8As shown, the extension plate 8 is provided with two first mounting grooves 9, and the two first engaging plates 10 are respectively arranged inside the two first mounting grooves 9, and the two first engaging plates 10 are placed in opposite directions in the two first mounting grooves 9. A second mounting groove 19 is provided on one side of the second follower block 18, and a second engaging plate 23 adapted to one of the first engaging plates 10 is arranged inside the second mounting groove 19. A third mounting groove 20 is provided in the middle of the first follower block 17, and a second engaging plate 23 adapted to the other first engaging plate 10 is also arranged inside the third mounting groove 20. A second engaging plate 23 adapted to the first follower block 10 is provided on one side of the first follower block 17, and a second engaging groove 22 is provided in the middle of the second follower block 18. The first engaging groove 21 and the second engaging groove 22 are respectively adapted to one side of the two first engaging plates 10 on the extension plate 8, so that when the first follower block 17 and the second follower block 18 are close to each other, one side of the two first engaging plates 10 is respectively sunken into the first engaging groove 21 and the second engaging groove 22 to prevent the first follower block 17 and the second follower block 18 from being blocked; the first follower block 17 and the second follower block 18 are respectively blocked; The following block 17 and the second following block 18 are initially kept in a separated state. At this time, the two first engaging plates 10 are respectively located in the two first mounting grooves 9 of the extension plate 8 and are placed in opposite directions, while the two second engaging plates 23 are respectively located in the second mounting groove 19 and the third mounting groove 20. As the mold body 2 approaches the locator, the bottom surface of the mold gradually pushes the second auxiliary positioning block 16, so that the second auxiliary positioning block 16 drives the first auxiliary positioning block 15 to move inward through the second connecting rod 14, and the first following block 17 and the second following block 18 begin to move toward the middle. When the first following block 17 and the second following block 18 gradually move closer, one side of the two first engaging plates 10 on the extension plate 8 enters the first wrapping groove 21 and the second wrapping groove 22 respectively to avoid interfering with the closing action of the following block. As the mold is further pressed down, the first engaging plate 10 and the second engaging plate 23 are accurately docked in the corresponding mounting grooves to complete the engaging action, ensuring the stable connection between the mold body 2 and the locator. In this process, the design of the first wrapping groove 21 and the second wrapping groove 22 effectively avoids the exposure of the engaging plate affecting the operation.

[0025] like Figure 5 , Figure 7 , Fig. 9As shown, a first push block 24 and a second push block 28 are fixedly installed on one side of the first engaging plate 10 and one side of the second engaging plate 23, respectively; a first rotating block 26 and a second rotating block 30 are rotatably installed on the middle part of one side of the first engaging plate 10 and the middle part of one side of the second engaging plate 23, respectively; a first connecting rotating plate 25 and a second connecting rotating plate 29 are fixedly connected on one side of the first rotating block 26 and one side of the second rotating block 30, respectively; a first connecting spring 27 and a second connecting spring 31 are fixedly connected on the middle parts of the first connecting rotating plate 25 and the second connecting rotating plate 29, respectively; the other ends of the first connecting spring 27 and the second connecting spring 31 are fixedly connected to one side of the first engaging plate 10 and the second engaging plate 23, respectively; the first rotating block 26 and the second rotating block 30 are both semicircularly arranged, and the first rotating block 26 is adapted to the second rotating block 30; a first connecting rotating plate 25 or a second connecting rotating plate 29 is also provided on one side of the first engaging plate 10 and one side of the second engaging plate 23 The first and second rotating blocks 26 and 30 are connected to each other by the push rod 32, and the push rod 32 passes through the through slot. When the first following block 17 and the second following block 18 are close to each other, the first fixed plate and the second fixed plate are gradually brought close to each other. As the two are close to each other, the first pushing block 24 enters the action range of the second fixed plate and pushes the second rotating block 30 to rotate along the direction of the fixed plate. At the same time, the second pushing block 28 enters the action range of the first fixed plate and pushes the first rotating block 26 to rotate along the direction of the fixed plate. Under the action of the pushing block, the first rotating block 26 and the second rotating block 30 are gradually forced to fit together. The semicircular structure enables the two rotating blocks to smoothly complete the closing process. As the first fixed plate and the second fixed plate are gradually merged, the first rotating block 26 and the second rotating block 30 finally reach a fully closed state. At this time, the action of the pushing block stops, and the two fixed plates are completely merged and engaged. When the limit needs to be released, it is only necessary to push the extended push rod 32 to slide to make the internal structure move in the opposite direction.
