[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 upper 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 automotive front floor stamping dies generally use manual demolding in the demolding process. It is difficult to accurately control the force and angle of manual operation, which can easily cause surface scratches, deformation and other damage to the molded workpiece during demolding, resulting in a decrease in product qualification rate and an increase in production costs. Therefore, an automotive front floor stamping die 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;

[0030] The mold section includes a fixed mold 21 and a movable mold 22, and the demolding section includes a threaded rod 23 and an ejector block 213;

[0031] The bottom surface of the fixed mold 21 is fixedly connected to the top surface of the base plate 1, and the bottom surface of the movable mold 22 is slidably connected to the top surface of the base plate 1. The side of the movable mold 22 near the fixed mold 21 contacts the outer wall of the fixed mold 21. A fixed frame 25 is fixedly installed on the outer wall of the base plate 1. The side of the threaded rod 23 near the movable mold 22 is fixedly connected to the outer wall of the movable mold 22. The side of the movable mold 22 near the fixed frame 25 extends through the inner side of the fixed frame 25 to the outer side of the fixed frame 25. A nut 24 is rotatably installed on the outer wall of the fixed frame 25 through a bearing seat. The inner side of the nut 24 is threadedly connected to the outer wall of the threaded rod 23. Two limit rails 26 are fixedly installed on the top surface of the base plate 1. Two limit sleeves 27 are slidably sleeved on the outer walls of the two limit rails 26 respectively. The outer walls of the sleeves 27 are fixedly connected to the outer walls of the movable mold 22. The outer wall of the fixed mold 21 is fixedly fitted with two positioning sleeves 29. The outer wall of the movable mold 22 is fixedly fitted with two positioning blocks 28. The outer walls of the two positioning blocks 28 are slidably connected to the inner sides of the two positioning sleeves 29 respectively. The bottom surface of the base plate 1 is provided with a through groove. The top block 213 is located on the inner wall of the through groove. The top surface of the top block 213 is in contact with the bottom surface of the movable mold 22. The bottom surface of the top block 213 is fixedly fitted with a pressing plate 210. The top surface of the pressing plate 210 is fixedly fitted with two pressing springs 212 and two pressing dampers 211. The top surfaces of the two pressing springs 212 and the two pressing dampers 211 are all fixedly connected to the bottom surface of the base plate 1. The initial state of the two pressing springs 212 is the extended state.

[0032] The stamping mechanism 3 includes a stamping head 39. Four limiting rods 35 are fixedly installed on the top surface of the base plate 1. A top plate 31 is fixedly installed on the top surface of each of the four limiting rods 35. A lifting plate 36 is slidably sleeved on the outer wall of each of the four limiting rods 35. The bottom surface of the lifting plate 36 is fixedly connected to the top surface of the stamping head 39. An electric telescopic rod 32 is fixedly installed on the top surface of the top plate 31. The bottom surface of the output end of the electric telescopic rod 32 extends through the top surface of the top plate 31 to the inner side of the top plate 31. The bottom surface of the output end of the electric telescopic rod 32 is fixedly connected to the top surface of the lifting plate 36. Two protective plates 33 are fixedly installed on the outer wall of the lifting plate 36. Two sets of buffer springs 37 and two sets of buffer dampers 38 are fixedly installed on the outer walls of the two protective plates 33 respectively. Two buffer plates 34 are fixedly installed on the two sets of buffer springs 37 and two sets of buffer dampers 38 respectively.

[0033] In use, the operator rotates the nut 24, and the threaded connection between the nut 24 and the threaded rod 23 causes the moving mold 22 to slide along the limit rail 26 on the base plate 1. When the moving mold 22 approaches the fixed mold 21, the positioning block 28 on the moving mold 22 slides into the positioning sleeve 29 on the fixed mold 21 to achieve precise positioning, ensure the positional accuracy when the mold is closed, and form a complete mold cavity. Then, the sheet metal to be stamped is placed in the mold cavity to complete the initial positioning of the workpiece.

[0034] When the electric telescopic rod 32 is activated, its output end pushes the lifting plate 36 downward along the limit rod 35. The lifting plate 36 drives the stamping head 39 to descend synchronously. The stamping head 39 gradually approaches and applies pressure to the sheet metal placed in the mold cavity. Under the action of the stamping mechanism, the sheet metal is stamped into shape according to the mold cavity. During this process, the protective plate 33, buffer spring 37, and buffer damper 38 on the outer wall of the lifting plate 36 can protect the stamping head 39, the workpiece, the fixed mold 21, and the moving mold 22, preventing external collisions from damaging the equipment during stamping.

[0035] After stamping is completed, the electric telescopic rod 32 retracts, driving the stamping head 39 and the lifting plate 36 to rise and reset. Then, the nut 24 is rotated again, causing the moving mold 22 to slide away from the fixed mold 21 and open the mold. At this time, the top block 213 located in the through groove on the bottom surface of the base plate 1 plays a role. Since the compression spring 212 is initially in the extended state, during the movement of the moving mold 22, the compression spring 212 and the compression damper 211 push the compression plate 210. The compression plate 210 drives the top block 213 to move upward. The top block 213 pushes the formed car front floor out of the mold, realizing the demolding operation, which facilitates the subsequent removal of the finished product.
