Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts manufacturing, in particular to a stamping lower die frame for an anti-collapse carriage tread pad. Background Art

[0002] Stamping is a forming method that uses a press and a die to apply external force to plates, strips, pipes and profiles to cause plastic deformation or separation, thereby obtaining a workpiece (stamping part) of the desired shape and size. Stamping and forging are both plastic processing (or pressure processing), collectively known as forging. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and strips. 60-70% of the world's steel is sheet material, most of which is stamped into finished products. There are also many parts on cars that need stamping, including car floor mats.

[0003] A Chinese patent with publication number CN220461963U discloses a stamping-resistant die frame, which can clamp and fix the two ends of the workpiece through a clamping component, further reinforce the workpiece, prevent the workpiece from loosening and deviating, avoid stamping deformation of the workpiece, and reduce the impact force through the elastic deformation force generated by the buffer component, thereby avoiding damage caused by violent collision between the upper die frame and the lower die frame to the greatest extent, ensuring the safe production of the stamping die frame.

[0004] In the above patent, the two ends of the workpiece to be pressed are fixed to avoid deformation of the workpiece during stamping. It is suitable for the stamping of small workpieces, but it is not suitable for stamping larger workpieces such as car floor mats. At the same time, there is a problem that the workpiece to be pressed is easily stuck inside the mold groove after the stamping operation is completed. Therefore, it does not meet the existing needs, and a collapse-proof car floor mat stamping lower mold frame is proposed. Utility Model Content

[0005] The utility model aims to provide a lower die frame for stamping an anti-collapse car tread mat. A support block is arranged inside the lower die plate, and ejector plates are arranged on the upper and lower surfaces of the support block. The upper surface of the upper ejector plate fits with the inner surface of the groove to form a continuous surface. A telescopic rod is arranged below the lower ejector plate. A workpiece to be pressed is fixed on the upper side of the lower die plate. The upper die plate is stamped downward, and the workpiece to be pressed is molded inside the convex block and the groove. After the stamping is completed, the upper die plate rises, and the telescopic rod extends to push up the upper plate, and the upper plate then pushes the car tread mat out of the groove, which can solve the problems in the prior art.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In order to solve the problem that it is not suitable for stamping large-volume workpieces such as car floor mats, and the problem that the workpiece is easy to get stuck inside the die groove after the stamping operation, please refer to Figure 1-4An embodiment of the utility model is as follows: a lower mold frame for stamping an anti-collapse car tread mat, comprising an upper mold plate 2 and a lower mold plate 4, wherein the lower mold plate 4 is located above the upper mold plate 2, and a groove 401 is arranged on the surface of the lower mold plate 4 facing the upper mold plate 2, and a through groove penetrating the upper and lower surfaces of the lower mold plate 4 is arranged inside the lower mold plate 4, and a support block 403 is arranged inside the through groove, a first ejection plate 402 is arranged above the support block 403, a second ejection plate 404 is arranged below the support block 403, a telescopic rod 405 is arranged below the second ejection plate 404, the telescopic rod 405 is externally connected to a motor, and a mounting platform 406 is arranged below the telescopic rod 405, a lower supporting plate 3 is arranged on the outer side of the mounting platform 406, a limiting column 7 is arranged inside the lower supporting plate 3, a spring 701 is arranged on the outer side of the limiting column 7, and the spring 701 is sleeved on the limiting column 7.

[0022] An upper support plate 1 is arranged above the upper template 2, a hydraulic press 101 is arranged on the upper support plate 1, the hydraulic press 101 is connected to the upper surface of the upper template 2 through a hydraulic rod, a protrusion 202 is arranged at the bottom of the upper template 2, and the upper surface of the first ejection plate 402 fits with the inner concave surface of the groove 401 to form a coherent surface.

[0023] A workpiece to be pressed is fixed on the top of the lower template 4. As the upper template 2 is punched downward by the hydraulic press 101, the protrusion 202 gradually approaches the groove 401, and the workpiece to be pressed is molded into the basic shape of the automobile compartment mat inside the protrusion 202 and the groove 401. After the punching is completed, the upper template 2 rises, and the telescopic rod 405 extends to push up the first ejection plate 402. The first ejection plate 402 then pushes the punched automobile compartment mat out of the interior of the groove 401, avoiding the situation where the automobile compartment mat is stuck in the groove 401 and needs to be manually removed, thereby further improving the production efficiency.

[0024] Four guide columns 201 extend upward from the lower support plate 3, the upper ends of the guide columns 201 are connected to the upper support plate 1, the upper template 2 is sleeved on the guide columns 201, a second limit plate 6 is arranged on the top of the lower support plate 3, a first limit plate 5 is arranged on the top of the second limit plate 6, one end of the limit column 7 is located inside the lower support plate 3, the limit column 7 extends upward and passes through the second limit plate 6 and the first limit plate 5 in sequence to the inside of the lower template 4, and the spring 701 is located between the lower template 4 and the first limit plate 5.

[0025] Due to the large overall weight of the automobile floor mat mold, a large amount of impact force is generated when the upper mold plate 2 is stamped downward. The impact force is directly applied to the lower mold plate 4, which will seriously shorten the life of the lower mold plate 4. The spring 701 absorbs the impact force applied to the lower mold plate 4 and transmits it to the lower support plate 3 below. The limit column 7 ensures that the lower mold plate 4 descends along the correct trajectory to contact the first limit plate 5, thereby increasing the overall service life of the mold and further reducing production costs.

[0026] Working principle: the workpiece to be pressed is fixed on the top of the lower template 4, at this time the hydraulic press 101 pushes the upper template 2 to punch downward, the protrusion 202 gradually approaches the groove 401, and the workpiece to be pressed is molded into the basic shape of the automobile compartment mat inside the protrusion 202 and the groove 401. After the punching is completed, the upper template 2 rises, and the telescopic rod 405 extends to push up the first ejection plate 402, and the first ejection plate 402 then pushes the punched automobile compartment mat out of the interior of the groove 401, avoiding the situation where the automobile compartment mat is stuck in the groove 401 and needs to be manually removed.
