[0002] Automotive molds are specialized process equipment used to manufacture automotive parts, covering the forming and processing of various components from body structure to interior and powertrain systems. Their core value lies in achieving consistent production of parts through high-precision molds, reducing material consumption, and supporting the forming needs of 60% to 80% of automotive parts. The level of mold design and manufacturing directly affects the production cost, quality, and R&D cycle of automobiles, hence they are known as the "mother of the automotive industry." Mold closing is a crucial step in automotive parts production, and its precision and stability directly affect product quality.

[0003] Some automotive molds are quite large, and the lowering and closing of the upper mold is carried out by hoisting. During the hoisting process, the upper mold will sway horizontally, so external force needs to be applied to align the upper and lower molds during the mold closing process. Therefore, an automotive mold upper and lower mold closing and aligning device is needed. This device uses a lateral moving plate to clamp and guide the upper mold from four sides during the lowering process, so that the upper and lower molds can be aligned before mold closing, thereby improving the accuracy and efficiency of mold closing and alignment.

A base plate 2 is welded to the surface of the processing table 1. A cylinder 3 is bolted to the top of the base plate 2. A carrier plate 4 is fixedly connected to the output end of the cylinder 3. A motor 5 is bolted to the bottom of the carrier plate 4. The output shaft of the motor 5 extends through to the top of the carrier plate 4 and is fixedly connected to a rotating plate 6. A slide rail 7 and a slider 8 are provided on the top of the carrier plate 4. Strips 9 are provided on the front, back, left, and right sides of the top of the carrier plate 4. The slide rail 7 is bolted to the carrier plate 4. The slider 8 is slidably connected to the slide rail 7. The strips 9 are fixedly connected to the slider 8. The rotating plate 6 and the strips 9 are rotatably connected via a rotating shaft. Connecting rod 10 and strip 9 are fixedly connected to connecting plate 11. The length of connecting plate 11 on the left and right sides is greater than that of connecting plate 11 on the front and rear sides. L-shaped plate 12 is welded to the surface of connecting plate 11. Bottom mold 14 is fixedly installed on the top of processing table 1 by bolts. Upper mold 15 is set above bottom mold 14. Insert rod 16 and insert sleeve 17 are fixedly connected to the surfaces of bottom mold 14 and upper mold 15 respectively. Washer 18 is glued to the top of bottom mold 14. Washer 18 is sleeved on the surface of insert rod 16. By setting washer 18, the top of bottom mold 14 is protected, avoiding collision noise when upper mold 15 directly contacts bottom mold 14 when mold closing, and reducing impact damage.

[0026] Example 2:

[0027] Figure 1-4This invention illustrates an embodiment of an automotive mold upper and lower mold closing and positioning device, comprising a processing table 1. A base plate 2 is welded to the surface of the processing table 1. A cylinder 3 is bolted to the top of the base plate 2. A carrier plate 4 is fixedly connected to the output end of the cylinder 3. A motor 5 is bolted to the bottom of the carrier plate 4. The output shaft of the motor 5 extends through to the top of the carrier plate 4 and is fixedly connected to a rotating plate 6. A slide rail 7 and a slider 8 are provided on the top of the carrier plate 4. Strip plates 9 are provided on the front, rear, left, and right sides of the top of the carrier plate 4. A connecting rod 10 is rotatably connected to the rotating plate 6 and the strip plates 9 via a rotating shaft. A connecting plate 11 is fixedly connected to the surface of the strip plates 9. An L-shaped plate 12 is welded to the surface of the connecting plate 11. Wear-resistant blocks 13 are adhered to the surface of the L-shaped plate 12. The wear-resistant block 13 protects the surface of the L-shaped plate 12, preventing it from directly contacting the upper mold 15 and causing rapid wear, thus improving the service life of the L-shaped plate 12. The bottom mold 14 is fixedly installed on the top of the processing table 1 with bolts, and the upper mold 15 is set above the bottom mold 14. The surfaces of the bottom mold 14 and the upper mold 15 are respectively fixedly connected with the insert rod 16 and the insert sleeve 17. Two symmetrically arranged limiting slide rods 19 are welded to the top of the base plate 2. The limiting slide rods 19 are slidably connected to the carrier plate 4. The limiting slide rods 19 limit the vertical movement of the carrier plate 4, preventing the carrier plate 4 from shaking during movement, thus improving the stability of the carrier plate 4 during movement.

[0028] Working Principle: When using this invention, the user lowers the upper mold 15 using a hoisting tool. At this time, the motor 5 drives the rotating plate 6 to rotate. With the cooperation of the rotating plate 6 and the connecting rod 10, the strip 9, through the connecting plate 11, drives the L-shaped plate 12 to clamp and guide the lowered upper mold 15. During this process, the sliding rail 7 and the slider 8 limit the movement of the strip 9, preventing it from wobbling during movement. This allows the insertion rod 16 and the insertion sleeve 17 to be properly positioned. After precise positioning and alignment, the upper mold 15 is lifted and moved upwards after the casting process. Following the steps described above, the L-shaped plate 12 is detached from the surface of the upper mold 15 and reset. Then, the carrier plate 4 is moved downwards by the cylinder 3 to facilitate the removal of the automotive parts from the bottom mold 14. This prevents the L-shaped plate 12 from obstructing the removal of the mold in the horizontal direction. The upper mold is clamped and guided from four sides during the downward movement of the lateral moving plate, which allows the upper and lower molds to be aligned before mold closing, thereby improving the alignment accuracy and efficiency of mold closing.

[0029] In summary, this automotive mold upper and lower mold closing and positioning device, through the cooperation of the rotating plate 6 and the connecting rod 10, enables the strip plate 9 to drive the L-shaped plate 12 via the connecting plate 11 to clamp and guide the lowered upper mold 15, thereby allowing the insert rod 16 and insert sleeve 17 to be accurately positioned and aligned. This achieves the goal of clamping and guiding the upper mold from four sides during the downward movement of the lateral moving plate, thus enabling the upper and lower molds to be aligned before mold closing, thereby improving the accuracy and efficiency of mold closing and alignment.
