Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to a molding die for an automotive fuel baffle. Background Technology

[0002] The fuel baffle is a core functional component of the vehicle's internal fluid management system. It is mainly used to control the flow path and stability of the oil in the engine, transmission, and fuel system. Its material is mostly thin steel sheet stamping or aluminum alloy casting. Therefore, the forming molds used for automotive fuel baffles are mostly stamping molds.

[0003] An existing automotive rudder baffle forming mold mainly involves manual loading and unloading by workers standing next to the stamping die. This loading method relies entirely on manual control. Since the metal sheet to be stamped needs to be placed in a designated position for stamping, the operation is time-consuming. Furthermore, workers' limbs frequently accidentally enter the stamping area, and the high-speed closing of the mold may lead to the risk of finger cuts or limb crushing injuries. Therefore, we propose an improved automotive rudder baffle forming mold. Summary of the Invention

[0004] The purpose of this application is to provide a mold for forming automotive oil baffles that can achieve automatic loading and unloading, thereby improving efficiency and safety by replacing manual operation with mechanical means.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: including a stamping assembly, a material conveying assembly, and a material stacking assembly, wherein the stamping assembly includes a portal frame, a hydraulic cylinder is fixedly connected to the top plate of the portal frame, an upper die is fixedly connected to the output end of the hydraulic cylinder, a lower die is provided below the upper die, a linear ball guide rail is fixedly connected to the inner wall of the vertical plate of the portal frame, and multiple sliders are slidably connected inside the linear ball guide rail;

[0006] The material handling assembly includes a support plate 1 and a support plate 2 fixedly connected to multiple sliders. A bidirectional lead screw rotates inside the support plate 1. Mounting blocks 1 are threaded onto the outer walls of both ends of the bidirectional lead screw. Mounting plates are fixedly connected to the outer walls of mounting blocks 1. A clamping plate is fixedly connected to the other end of the mounting plate. An electric push rod is fixedly connected to the upper end of the support plate 2. Mounting blocks 2 are fixedly connected to the output end of the electric push rod. A connecting plate is fixedly connected to the outer wall of mounting blocks 2. An electric cylinder and an air cylinder are fixedly connected to the upper end of the connecting plate. A piston slides inside the air cylinder. The output end of the electric cylinder is fixedly connected to the piston. An air pipe is fixedly connected to the lower end of the air cylinder. The other end of the air pipe passes through the connecting plate and is fixedly connected to a suction cup.

[0007] As a preferred embodiment, guide posts are fixedly connected to the lower end face of the upper mold near the four corners, and guide holes are opened on the upper end face of the lower mold near the four corners, with the guide posts slidingly connected to the guide holes.

[0008] As a preferred embodiment, both support plate one and support plate two are provided in two pieces, and support plate one and support plate two on the same side are fixedly connected by a horizontal plate. Both support plate one and support plate two have sliding grooves on their outer walls, and mounting block one and mounting block two are slidably connected in the sliding grooves.

[0009] As a preferred embodiment, the opposing surfaces of the upper and lower clamping plates on the same side are both made of bevels and are matched with each other, with the height of the lower clamping plate near the suction cup being greater than the height of the other side.

[0010] As a preferred embodiment, a servo motor is fixedly installed inside the support plate, and the output end of the servo motor is fixedly connected to the upper end of the bidirectional lead screw.

[0011] As a preferred embodiment, a limiting ring is fixedly connected inside the air cylinder. The limiting ring is located on the side of the air pipe near the electric cylinder, and the diameter of the piston is larger than the opening diameter of the limiting ring.

[0012] As a preferred embodiment, the material stacking assembly includes a waste receiving box, a material receiving box, and a support column. The waste receiving box and the support column are respectively located on both sides of the stamping assembly. The material receiving box is located on one side below the lower die, and a support frame is fixedly connected to the upper end of the support column.

[0013] Compared with the prior art, the beneficial effects of this application are as follows:

[0014] By coordinating the stamping and material handling components, an electric cylinder can drive a piston to generate positive and negative pressure in the air cylinder. This pressure is then used to grip and place the metal sheet to be stamped via a suction cup. This enables automatic loading of the metal sheet and removal of the stamped die from the lower mold cavity. The bidirectional lead screw controls the relative movement of the upper and lower mounting blocks, which in turn drives the clamping plate to hold the scrap edges generated by the stamping. This allows for fully automated production of automotive fuel baffles, eliminating the need for manual loading and unloading and manual insertion into the stamping area, thus improving efficiency and safety.

[0015] By using the stacking components, the waste collection box can be used to collect the waste edges and the forming mold, thus achieving classified storage. At the same time, the support columns and support frames are used to support and stack the metal plates to be punched, making it convenient for the suction cup to grab and load the materials.

[0025] like Figure 1-4 The diagram shows a molding die for an automotive fuel baffle, comprising a stamping assembly 1, a material conveying assembly 2, and a material stacking assembly 3. The stamping assembly 1 includes a portal frame 11, with a hydraulic cylinder 12 fixedly connected to the top plate of the portal frame 11. An upper die 13 is fixedly connected to the output end of the hydraulic cylinder 12. A lower die 16 is disposed below the upper die 13 and is fixed to the side wall of a linear ball bearing guide 15 via a bracket. The punch of the upper die 13 is matched with the cavity of the lower die 16, and the cavity of the lower die 16 is matched with the shape of the automotive fuel baffle. The stamping die for the vehicle baffle is an existing mechanism, so its shape will not be described in detail here. It is simplified in the figure. A linear ball guide 15 is fixedly connected to the inner wall of the vertical plate of the portal frame 11. Multiple sliders 18 are slidably connected inside the linear ball guide 15. The linear ball guide 15 is composed of two slides located on both sides of the lower die 16. One of them is equipped with a ball screw that drives the slider 18 to move, and the other is equipped with a smooth guide rod for limiting the movement of the drive slider 18, so as to ensure the stable movement of the material conveying component 2 above it.

[0026] The material handling assembly 2 includes a first support plate 21 and a second support plate 22 fixedly connected to multiple sliders 18. The specific number of sliders 18 matches the number of first support plates 21 and second support plates 22. A bidirectional lead screw 24 rotates inside the first support plate 21. Mounting blocks 25 are threaded onto the outer walls of both ends of the bidirectional lead screw 24. Mounting plates 26 are fixedly connected to the outer walls of mounting blocks 25. A clamping plate 27 is fixedly connected to the other end of the mounting plate 26. An electric push rod 28 is fixedly connected to the upper end of the second support plate 22. A second mounting block 29 is fixedly connected to the output end of the electric push rod 28. A connecting plate 210 is fixedly connected to the outer wall of block 29. An electric cylinder 211 and an air cylinder 212 are fixedly connected to the upper end of the connecting plate 210. A piston 215 is slidably arranged inside the air cylinder 212. The output end of the electric cylinder 211 is fixedly connected to the piston 215. An air pipe 213 is fixedly connected to the lower end of the air cylinder 212. The other end of the air pipe 213 passes through the connecting plate 210 and is fixedly connected to a suction cup 214. By using the electric cylinder 211 to drive the piston 215 to move inside the air cylinder 212, a positive and negative pressure difference can be created, so that the suction cup 214 has the suction force to grab the metal plate to be punched.

[0027] Guide posts 14 are fixedly connected to the lower end face of the upper die 13 near the four corners, and guide holes 17 are opened on the upper end face of the lower die 16 near the four corners. The guide posts 14 are slidably sleeved with the guide holes 17 to facilitate the positioning of the upper die 13 and the lower die 16, and to facilitate stable stamping operations.

[0028] Support plate 1 21 and support plate 22 are provided in two pieces, and support plate 1 21 and support plate 22 on the same side are fixedly connected by a horizontal plate. Sliding grooves are provided on the outer walls of support plate 1 21 and support plate 22. Mounting block 1 25 and mounting block 29 are slidably connected in the sliding grooves. The sliding grooves limit the movement of mounting block 1 25 and mounting block 29, thereby improving the stability of mounting block 1 25 and mounting block 29 when they move.

[0029] The opposing surfaces of the upper and lower clamping plates 27 on the same side are both made of bevels and are matched with each other. The lower clamping plate 27 is higher on the side closer to the suction cup 214 than on the other side. This makes it convenient for the frame to be tilted when the scrap metal frame is clamped by the clamping plate 27, so that the frame can fall automatically under the influence of gravity after the clamping plate 27 is released.

[0030] A servo motor is fixedly installed inside the support plate 21. The output end of the servo motor is fixedly connected to the upper end of the bidirectional lead screw 24. The servo motor drives the bidirectional lead screw 24 to rotate, thereby controlling the relative movement of the two adjacent mounting blocks 25.

[0031] A limiting ring 23 is fixedly connected inside the air cylinder 212. The limiting ring 23 is located on the side of the air pipe 213 near the electric cylinder 211. The diameter of the piston 215 is larger than the opening diameter of the limiting ring 23. The movement of the piston 215 is limited by the limiting ring 23 to prevent the piston 215 from getting stuck above the air pipe 213 when it is installed.

[0032] The stacking assembly 3 includes a waste receiving box 31, a material receiving box 32, and a support column 33. The waste receiving box 31 and the support column 33 are respectively located on both sides of the stamping assembly 1. The material receiving box 32 is located on one side below the lower die 16. The upper end of the support column 33 is fixedly connected to a support frame 34. Multiple metal plates to be stamped are stacked on top of the support frame 34.

[0033] Working principle: Before stamping, multiple metal plates to be stamped are stacked on the support frame 34. Then, the slider 18 on the linear ball guide 15 drives the material conveying component 2 to reciprocate, thereby moving the suction cup 214 above the metal plate to be stamped. Then, the electric push rod 28 drives the mounting block 29 to descend, and then the connecting plate 210 drives the suction cup 214 to descend and press against the surface of the metal plate to be stamped. Then, the electric cylinder 211 drives the piston 215 to move, so that the air cylinder 212 generates negative pressure, thereby allowing the suction cup 214 to grab the metal plate to be stamped and rise through the air pipe 213. Then, the linear ball guide 15 drives the slider 18 to move, so that the suction cup 214 moves the metal plate to be stamped above the lower die 16. Then, the electric cylinder 211 drives the piston 215 to move in the opposite direction, so that the suction cup 214 puts down the metal plate to be stamped and moves to the next position.

[0034] During stamping, the metal plate is located between two adjacent clamping plates 27. The hydraulic cylinder 12 is activated to drive the upper die 13 to descend. Under the guidance of the guide post 14 and the guide hole 17, the punch of the upper die 13 can stably enter the mold cavity of the lower die 16 to complete the stamping action. After the stamping is completed, the upper die 13 is reset.

[0035] After stamping, the servo motor is activated to drive the bidirectional lead screw 24 to rotate, which in turn drives the upper and lower mounting blocks 25 to move relative to each other. This, in turn, drives the clamping plates 27 to move relative to each other through the mounting plate 26, clamping the scrap metal frame generated during stamping. The clamping position is in the middle of the scrap metal frame, biased towards the suction cup 214. Then, the linear ball guide rail 15 drives the slider 18 to move, moving the suction cup 214 again above the lower die 16. Following the same principle, the suction cup 214 grabs the formed oil baffle mold again. Then, the slider 18 continues to move, moving the scrap metal frame above the waste receiving box 31. At this time, the formed oil baffle mold is above the receiving box 32. The two clamping plates 27 are then controlled to move in opposite directions, so that the scrap metal frame tilts and slides into the waste receiving box 31 under the influence of gravity. At the same time, the suction cup 214 releases the formed oil baffle mold, allowing it to fall into the receiving box 32, thus completing the classification and storage of the products, which is convenient and time-saving.

Those skilled in the art should understand that this application is not limited to the above embodiments.
