Description

Technical Field

[0001] This utility model relates to the field of automotive processing and manufacturing technology, and more specifically, to a molding die for a lightweight vehicle skid plate. Background Technology

[0002] In today's rapidly developing automotive industry, lightweighting has become an important development direction for improving vehicle energy efficiency and reducing energy consumption. As an important component protecting the vehicle body structure and key parts, vehicle skid plates are also gradually shifting towards lightweight, high-strength composite materials or alloys. The molding quality of lightweight vehicle skid plates largely depends on the performance and reliability of the molding mold.

[0003] Currently, the molding dies for lightweight vehicle skid plates typically rely on manual or automatic mold-locking systems for fixation during the mold-closing process. However, manual mold-locking is highly dependent on the operator's experience and sense of responsibility, and is easily affected by operator negligence, forgetfulness, or improper operation, leading to incomplete or absent mold locking. This can result in mold misalignment or displacement during subsequent molding processes, affecting not only the molding accuracy and product quality of the skid plate but also potentially causing mold damage, equipment failure, and other safety hazards. While automatic mold-locking systems reduce human interference to some extent, they rely on the coordinated operation of precision components such as sensors, hydraulic or pneumatic elements. If these components malfunction, age, or experience abnormal signal transmission, the automatic mold-locking system will fail, unable to achieve effective mold locking and facing similar risks as manual mold-locking. The vehicle body guard plate processing mold, patent document publication number CN220698025U, is designed to facilitate the removal of workpieces. However, it still has some drawbacks in actual use. For example, if the automatic mold locking system malfunctions or manual mold locking is forgotten, problems such as mold misalignment and displacement may occur during subsequent molding processes. This will not only affect the molding accuracy and product quality of the guard plate, but may even lead to safety hazards such as mold damage and equipment failure. Utility Model Content

[0021] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0022] As attached Figure 1 To be continued Figure 4This utility model provides a molding die for a lightweight vehicle skid plate, comprising: an upper die 1 and a lower die 3. A limiting post 9 and a C-shaped post 11 are fixedly connected to the side surface of the lower die 3. A movable post 10 is slidably connected within the limiting post 9. A connecting piece 15 is rotatably connected to the movable post 10. A rotating shaft 14 is rotatably connected to the other end of the connecting piece 15. A movable block 13 and a connecting block 16 are fixedly connected to both ends of the rotating shaft 14, respectively. A movable groove 12 is provided on the C-shaped post 11. The movable block 13 is located within the movable groove 12 and slidably connected to the movable groove 12. A reset component is provided on the connecting block 16. A fixing block 7 and a flange 5 are fixedly connected to the side surface of the upper die 1. An extrusion post 8 is fixedly connected to the lower surface of the fixing block 7. The size of the extrusion post 8 is the same as that of the movable post 10 and slidably connected to the limiting post 9. A fixing block 23 is fixedly connected to the side surface of the lower die 3. A sliding member 24 is slidably connected within the fixing block 23, and the sliding member 24 is away from the fixing block. A rotating block 6 is rotatably connected to one end of the second mold 23. A pawl 4 is fixedly connected to the side surface of the rotating block 6. The pawl 4 is connected to the reset assembly via a connecting rod 25. The reset assembly includes a limiting rod 19, which passes through the connecting block 16 and is slidably connected to the connecting block 16. A spring 18 is provided on the outside of the connecting block 16. The two ends of the spring 18 are fixedly connected to the side surfaces of the two connecting blocks 16 respectively. The reset assembly also includes a second connecting block 17, which is fixedly connected to the side surface of the connecting block 16. A limiting rod 22 is provided through the connecting block 16 and is slidably connected to the connecting block 16. A spring 20 is fixedly connected to the lower surface of the connecting block 27. A support plate 21 is fixedly connected to the end of the spring 20 away from the connecting block 27. The bottom end of the limiting rod 22 is fixedly connected to the upper surface of the support plate 21. A connecting plate 2 is fixedly connected to the upper surface of the upper mold 1. All structures on the upper mold 1 and the lower mold 3 are symmetrically arranged.

[0023] Specifically, a downward force is applied by the connecting plate 2 on the upper surface of the upper mold 1, causing the upper mold 1 to move closer to the lower mold 3. At this time, the extrusion column 8 and the fixing block 7 on the side surface of the upper mold 1 move down synchronously with the upper mold 1, and all components on the lower mold 3 are in their initial positions. The springs 18 and 20 in the reset assembly are in their naturally extended state. When the upper mold 1 moves down to a certain position, the extrusion column 8 on the lower surface of the fixing block 7 inserts into the limiting column 9 of the lower mold 3 and contacts the movable column 10 inside the limiting column 9. The extrusion column 8, which continues to move down, pushes the movable column 10 to slide down within the limiting column 9. When it moves downward, it drives the connecting piece 15, which is rotatably connected to it, to rotate. The other end of the connecting piece 15 drives the movable block 13 and the connecting block 16 to move through the rotating shaft 14. The movable block 13 slides outward along the groove 12 in the C-shaped column 11. The connecting block 16 moves outward under the restriction of the limiting rod 19, so that the spring 18 is stretched. At the same time, when the connecting block 16 moves into the movable groove 12 in the vertical direction of the C-shaped column 11, it drives the connecting block 17 to move downward. The connecting block 17 compresses the spring 20. The limiting rod 22 slides along the connecting block 16 and is kept stable by the support plate 21. The reset assembly completes energy storage.

[0024] When the movable block 13 moves to the end of the movable groove 12, the upper mold 1 and the lower mold 3 gradually fit together. When the connecting block 27 in the reset assembly moves the connecting rod 25, it rotates first and then descends, causing the rotating block 6 to drive the sliding part 24 to slide within the fixed block 23. During the rotation of the rotating block 6, the pawl 4 rotates inward until the pawl 4 engages with the flange 5, thus locking the upper mold 1 and the lower mold 3. At this time, the upper mold 1 and the lower mold 3 are completely fitted together, completing the closure of the molding cavity for the lightweight vehicle guard plate. In the mold-closed state, the material is formed and processed through the mold cavity. The process forms a lightweight vehicle guard plate. After processing, the connecting plate 2 drives the upper mold 1 to move upward, the extrusion column 8 gradually disengages from the limiting column 9, and the spring 18 and spring 20 release elastic potential energy, causing the connecting block 16 and connecting block 2 17 to reset. Through the rotating shaft 14 and connecting piece 15, the movable column 10 and movable block 13 are driven back to their initial positions. At the same time, the chuck 4 rotates, causing the flange 5 of the upper mold 1 to be released. Under the action of the reset force, the sliding piece 24 and rotating block 6 are reset, the chuck 4 returns to its initial state, and the upper mold 1 and lower mold 3 are completely separated, completing one molding cycle.

[0025] The working process of this utility model is as follows: the upper mold 1, the lower mold 3 and each component are in the initial position. The spring 18 and the spring 20 in the reset assembly are naturally extended. A downward force is applied through the connecting plate 2 on the upper surface of the upper mold 1, which drives the upper mold 1 to move closer to the lower mold 3. The extrusion column 8 and the fixing block 7 on the side surface of the upper mold 1 move down synchronously with the upper mold 1. When the upper mold 1 moves down to a certain position, the extrusion column 8 on the lower surface of the fixing block 7 is inserted into the limiting column 9 of the lower mold 3 and contacts the movable column 10 in the limiting column 9. The extrusion column 8, which continues to move down, pushes the movable column 10 to slide down in the limiting column 9. The movable column 10 moves downward, causing the connecting piece 15, which is rotatably connected to it, to rotate. The other end of the connecting piece 15 drives the movable block 13 and the connecting block 16 to move through the rotating shaft 14. The movable block 13 slides outward along the groove 12 in the movable groove of the C-shaped column 11. The connecting block 16 moves outward under the restriction of the limiting rod 19, causing the spring 18 to be stretched. At the same time, when the connecting block 16 moves into the movable groove 12 in the vertical direction of the C-shaped column 11, it causes the connecting block 17 to move downward. The connecting block 17 compresses the spring 20 (the limiting rod 22 slides along the connecting block 16 and is kept stable by the support plate 21). The reset assembly completes energy storage.

[0026] When the movable block 13 moves to the end of the movable groove 12, the upper mold 1 and the lower mold 3 gradually fit together; the connecting block 27 in the reset assembly drives the connecting rod 25 to move (first rotate and then descend), so that the rotating block 6 drives the sliding part 24 to slide in the fixed block 23. During the rotation of the rotating block 6, the pawl 4 rotates inward until it engages with the flange 5, thereby locking the upper mold 1 and the lower mold 3. At this time, the two are completely fitted together, completing the closure of the molding cavity of the lightweight vehicle guard plate. In the mold-closed state, the material is formed through the mold cavity to form a lightweight vehicle guard plate. After processing, the connecting plate 2 drives the upper mold 1 to move upward, and the extrusion column 8 gradually disengages from the limiting column 9. Spring 18 and spring 20 release elastic potential energy, causing connecting block 16 and connecting block 27 to reset. Through the rotating shaft 14 and connecting piece 15, the movable column 10 and movable block 13 are driven back to their initial positions. At the same time, the chuck 4 rotates to release the flange 5 of the upper mold 1. Under the action of the reset force, the sliding piece 24 and rotating block 6 are reset, the chuck 4 returns to its initial state, and the upper mold 1 and lower mold 3 are completely separated, completing one molding cycle.
