Description

Technical Field

[0001] The present invention relates to the technical field of stamping dies, and in particular to a new energy vehicle door die that is convenient for lowering the die. Background Art

[0002] The outer panel of a car door is a thin plate stamping part that makes up the car body. It has the characteristics of thin material, complex shape, large structure and size, and high surface quality requirements. During the stamping process, the upper mold descends so that the upper mold core fits on the lower mold core, pressing the outer panel of the car door into shape.

[0003] After stamping, new energy vehicle door panels are typically unloaded using suction cups on a robotic arm. However, due to the large window frame area on the door panel and the narrow frame of the door panel in this area, the robotic arm's suction doesn't capture the window frame. This results in uneven suction, causing the panel to not remain level, and causing one side of the window frame area to drop slightly, making it susceptible to damage during the unmolding process. Summary of the Invention

[0004] The purpose of the present invention is to provide a new energy vehicle door mold that is easy to lower the mold, prevent the door window frame area from deforming during stamping, and facilitate the unloading robot to absorb and lift the door, making it easier to lower the mold of the door.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a new energy vehicle door mold that is convenient for lower molding, comprising: a lower mold base and an upper mold base, the lower mold base is provided with a punch, and the upper mold base is provided with a forming groove whose shape matches the punch, the workpiece to be formed is placed on the lower mold base, the workpiece to be formed is provided with a window through hole, symmetrically arranged floating parts are provided on both sides of the punch, the floating parts contact the bottom of the workpiece to be formed, and the punch is also provided with a supporting part whose shape matches the window through hole, the supporting part is detachably mounted on the punch, and a number of springs are provided under the supporting part, the springs are fixedly mounted on the punch, symmetrically arranged supporting edges are provided on both sides of the supporting part, the supporting edges contact the bottom surface of the workpiece to be formed, a first suction cup for adsorbing the workpiece to be formed is provided on the unloading robot, and a second suction cup for adsorbing the supporting part is also provided on the unloading robot.

For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0035] See also Figure 1-6 The present invention provides a technical solution: a new energy vehicle door mold that is convenient for lower molding, comprising: a lower mold base 1 and an upper mold base 2, the lower mold base 1 is provided with a punch 11, the upper mold base 2 is provided with a forming groove 21 whose shape matches the punch 11, the workpiece 3 to be formed is placed on the lower mold base 1, the workpiece 3 to be formed is provided with a window through hole 31, symmetrically arranged floating parts 4 are provided on both sides of the punch 11, the floating parts 4 contact the bottom of the workpiece 3 to be formed, the punch 11 is also provided with a supporting part 5 whose shape matches the window through hole 31, the supporting part 5 is detachably mounted on the punch 11, a plurality of springs 6 are provided under the supporting part 5, the spring 6 is fixedly mounted on the punch 11, symmetrically arranged supporting edges 51 are provided on both sides of the supporting part 5, the supporting edges 51 contact the bottom surface of the workpiece 3 to be formed, the unloading manipulator 7 is provided with a first suction cup 71 for adsorbing the workpiece 3 to be formed, and the unloading manipulator 7 is also provided with a second suction cup 72 for adsorbing the supporting part 5.

[0036] The support member 5 also includes a frame 54 and a central support plate 52. At least one central support plate 52 is disposed within the frame 54, and the second suction cup 72 adheres to the central support plate 52. The frame 54 is shaped to match the window opening 31. The support member 5 is not a monolithic entity, but rather is formed by combining the central support plate 52 and the frame 54. This effectively reduces the weight of the support member 5 and prevents it from affecting the door's adhesion while maintaining the desired positioning.

[0037] The back of the supporting member 5 is provided with a plurality of slots 53 , into which the springs 6 are inserted, thereby realizing a detachable elastic connection of the supporting member 5 and facilitating separation of the supporting member 5 and the punch 11 .

[0038] Symmetrically arranged slide rails 55 are provided on opposite inner walls of the frame 54, and the central support plate 52 is slidably connected to the slide rails 55. The central support plate 52 can be slid to adjust its position to facilitate suction by the suction cup. After the central support plate 52 is positioned, it can be fixed to the slide rails 55 with screws to prevent position shifting.

[0039] There are two central support plates 52 , which effectively support the frame of the supporting member 5 and prevent the supporting member 5 from deforming.

[0040] A protrusion 41 is provided at one end of the floating member 4, which abuts against the side of the workpiece 3 to be formed. This forms an "L"-shaped structure of the floating member 4. The floating members 4 at both ends of the workpiece 3 cooperate with the supporting members 5 to effectively prevent the workpiece 3 from shifting horizontally, ensuring molding quality and facilitating the lowering of the workpiece 3 from the mold.

[0041] The thickness of the bump 41 is equal to the thickness of the plate body of the workpiece 3 to be formed, which effectively positions the workpiece 3 to be formed while not affecting the extrusion forming of the workpiece 3 to be formed.

[0042] Working principle: When the workpiece 3 to be formed is not placed on the lower die base 1, the supporting member 5 is pushed upward by the spring to position the workpiece 3 to be formed, making it easier to place the workpiece 3 to be formed. Figure 1 .

[0043] When the workpiece 3 to be formed is placed on the lower die base 1 for forming, the supporting member 5 is squeezed downward and received in the punch 11. At this time, the side of the workpiece 3 to be formed is supported by the floating member 4. Figure 2 .

[0044] After that, the upper die base 2 moves downward, the lower die base 1 and the upper die base 2 are closed, and the workpiece 3 to be formed is extruded and formed. The floating part 4 is extruded downward and is received in the corresponding groove on the lower die base 1. Figure 3 .

[0045] Finally, the upper die base 2 moves upward, and the lower die base 1 and the upper die base 2 are separated. After the workpiece 3 is extruded and formed, it is lifted up by the floating part 4 and separated from the punch 11. Since the supporting part 5 is not squeezed, it also moves upward and remains inserted into the window through-hole 31. The unloading robot 7 uses the first suction cup 71 to absorb one side of the workpiece 3 to be formed. For the side of the window through-hole 31 of the workpiece 3 to be formed, the unloading robot 7 uses the second suction cup 72 to absorb the supporting part 5 to lift it. The supporting edge 51 of the supporting part 5 supports the car door window frame, and the supporting edge 51 supports the car door window frame to ensure the adsorption effect of the workpiece 3 to be formed. See the attached Figure 4 Before the next stamping process, the supporting member 5 is re-placed on the punch 11 .

[0046] During the door panel forming process, the support member 5 positions the workpiece 3, preventing it from shifting during loading and forming, and preventing deformation of the door frame during stamping. Furthermore, the removable support member 5 facilitates the unloading robot's ability to lift the door after forming, keeping it level and preventing damage from collisions, allowing for easier removal from the mold.

[0047] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
