Description
Technical Field
[0001] This utility model relates to the field of automotive front floor technology, specifically to an automatic demolding stamping mold for automotive front floor. Background Technology
[0002] The front floor of a car is an important component of the lower part of the vehicle body. It mainly bears the weight of the front seats and front passengers. It is also part of the body structure and participates in bearing the weight of the body structure. Together with the A, B, C pillars and front and rear partitions, it forms the passenger compartment and supports the weight of the vehicle body, opening and closing parts and other assemblies and related accessories. The front floor of a car needs to be stamped during the production process.
[0003] A stamping die is a device that uses pressure to deform or separate materials. Stamping dies have a wide range of applications, such as the forming of the front floor of an automobile.
[0004] Existing stamping dies mostly rely on manual demolding in the demolding process. Operators need to manually remove the formed workpiece from the die with the help of tools. It is difficult to accurately control the force and angle of the operation during removal, which can easily cause scratches and deformation on the surface of the workpiece. Therefore, an automatic demolding stamping die for the front floor of an automobile is proposed. Utility Model Content

[0028] Please see Figure 1-5 The present invention provides a technical solution: including a base plate 1, and a mold mechanism 2 and a stamping mechanism 3 are arranged on the top of the base plate 1;
[0029] Mold mechanism 2 includes a mold section and a demolding section;
[0030] The mold section includes a mold 21, and the demolding section includes an ejector block 22 and two sets of extrusion inclined blocks 211;
[0031] A fixed frame 23 is fixedly installed on the top surface of the base plate 1. The top surface of the fixed frame 23 is fixedly connected to the bottom surface of the mold 21. Two sets of sliding grooves are opened on the outer wall of the mold 21. The outer walls of the two sets of extrusion inclined blocks 211 are slidably connected to the inner walls of the two sets of sliding grooves, respectively. The top block 22 is located inside the fixed frame 23. The top surface of the top block 22 slides through the inner top surface of the fixed frame 23 and the bottom surface of the mold 21, extending to the inner side of the mold 21. A demolding damper 26 and a demolding spring 27 are fixedly installed on the inner side of the fixed frame 23. The top surfaces of the demolding damper 26 and the demolding spring 27 are fixedly connected to the bottom surface of the top block 22. The demolding spring 27 is initially in an extended state. Two connecting plates 210 are fixedly installed on the opposite side of the two sets of extrusion inclined blocks 211. Two through grooves are opened on the outer wall of the fixed frame 23. Two lifting frames 24 are respectively provided on the inner walls of the two through slots. Two control plates 25 are respectively hinged to the inner sides of the two lifting frames 24. The side of the two control plates 25 near the two connecting plates 210 is respectively hinged to the outer wall of the two connecting plates 210. The side of the two lifting frames 24 near the top block 22 is fixedly connected to the bottom surface of the top block 22. Two sets of limiting posts 28 are fixedly provided on the bottom surface of the inner side of the fixed frame 23. The top surfaces of the two sets of limiting posts 28 slide through the bottom surfaces of the two lifting frames 24 and extend to the inner side of the two lifting frames 24. Two sets of limiting rods 29 are fixedly provided on the outer wall of the mold 21. The side of the two sets of limiting rods 29 far apart slides through the side of the two connecting plates 210 near the mold 21 and extends to the side of the two connecting plates 210 away from the mold 21.
[0032] The stamping mechanism 3 includes a stamping block 34. A fixed frame 31 is fixedly installed on the top surface of the base plate 1. An electric telescopic rod 33 is fixedly installed on the top surface of the fixed frame 31. The bottom surface of the output end of the electric telescopic rod 33 extends through the top surface of the fixed frame 31 to the inner side of the fixed frame 31. A lifting plate 35 is fixedly installed on the bottom surface of the output end of the electric telescopic rod 33. The bottom surface of the lifting plate 35 is fixedly connected to the top surface of the stamping block 34. Two limiting plates 32 are fixedly installed on the top surface of the lifting plate 35. The top surfaces of the two limiting plates 32 slide through the inner side of the fixed frame 31 and extend above the fixed frame 31. Multiple buffer rods 37 slide through the bottom surface of the lifting plate 35 and extend above the lifting plate 35. Multiple buffer springs 36 are respectively sleeved on the outer wall of the multiple buffer rods 37. The bottom surfaces of the multiple buffer springs 36 are fixedly connected to the outer wall of the multiple buffer rods 37. The top surfaces of the multiple buffer springs 36 are fixedly connected to the bottom surface of the lifting plate 35.
[0033] In use, during the stamping preparation stage, the sheet metal to be stamped is placed inside the mold 21. During the stamping process, the electric telescopic rod 33 is activated. The output end of the electric telescopic rod 33 moves downward, driving the lifting plate 35 and the stamping block 34 to move down together. The limiting plate 32 on the top surface of the lifting plate 35 slides on the inner side of the fixed frame 31 to ensure that the lifting plate 35 and the stamping block 34 move down smoothly in the vertical direction and avoid deviation. At the same time, the buffer rod 37 and the buffer spring 36 on the bottom surface of the lifting plate 35 work together. When the stamping block 34 contacts the sheet metal, the buffer spring 36 is compressed and contracts, and the buffer rod 37 slides inside the lifting plate 35, which plays a buffering and shock absorption effect, reducing the impact force at the moment of stamping, protecting the mold and equipment, and allowing the sheet metal to gradually form into the shape of the front floor of a car under the pressure of the stamping block 34.
[0034] After stamping, the demolding stage begins. The output end of the electric telescopic rod 33 retracts upward, causing the lifting plate 35 and the stamping block 34 to move upward and reset. During the upward movement of the lifting plate 35, the demolding spring 27 and the demolding damper 26 can cause the top block 22 to move upward. When the top block 22 moves upward, it pushes the formed front floor of the car out from the inside of the mold 21. The upward movement of the top block 22 can also drive the two lifting frames 24 to move synchronously. Since the control plate 25, which is hinged to the inner side of the two lifting frames 24, is hinged to the connecting plate 210 of the extrusion inclined block 211, the upward movement of the lifting frame 24 will push the connecting plate 210 and the extrusion inclined block 211 to slide inside the mold 21 through the control plate 25. When the extrusion inclined block 211 slides, its inclined structure will extrude the side of the stamped workpiece, thereby further separating the workpiece from the mold 21. The limiting rod 29 plays a limiting and guiding role on the connecting plate 210, ensuring the stability and accuracy of the sliding of the extrusion inclined block 211.
