Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a composite mold for trimming and punching automotive panel. Background Technology

[0002] A car tailgate, also known as a car lift tailgate, car folding tailgate, car loading and unloading tailgate, lifting tailgate, or hydraulic car tailgate, is a hydraulic lifting and loading device powered by the vehicle's battery, installed at the rear of trucks and various vehicles. Nowadays, in the production process of car tailgates, it is necessary to use molds for trimming and hole drilling to facilitate the subsequent assembly of the car tailgates.

[0003] The existing utility model patent with application number CN202223475682.0 proposes a composite mold for trimming and punching automobile panels, including an upper mold base, a lower mold base, a support base, a shock-absorbing pad, a guide post, a guide sleeve one and a guide sleeve two. The upper mold base includes an upper mold core and a punching part... It can monitor the placement position of the automobile panel, and when its position is inaccurate, it can sound an alarm and stop the punching and trimming work, so as to avoid the problem that the automobile panel after punching and trimming is unusable due to inaccurate position;

[0004] Despite the numerous advantages shown in the comparison document, a significant drawback is that after the punching operation, debris tends to accumulate in the punched hole of the die core. This not only interferes with subsequent punching operations but also reduces the convenience of operation and overall practicality to some extent, requiring urgent optimization and improvement.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-3 A composite mold for trimming and punching automotive panel includes a lower mold base 1, a lower mold core 2, and a punch 3. The lower mold core 2 is fixed to the upper end of the lower mold base 1, and the punch 3 is located at the upper end of the lower mold core 2. The lower mold base 1 has a storage groove, and the inner top of the storage groove has a discharge hole 4 corresponding to the punch 3, which allows residue to fall into the storage groove. The outer side wall of the lower mold base 1 has an installation groove, and the inner bottom of the installation groove is fixedly connected to an exhaust fan 6 that communicates with the storage groove, which is used to draw airflow. A sealing ring 13 is fixedly sleeved on the exhaust fan 6 to improve the sealing between the exhaust fan 6 and the inner side wall of the storage groove. One side of the sealing ring 13 is fixedly connected to the inner side wall of the installation groove. A filter screen 7 is fixedly embedded in the storage groove on the side facing the exhaust fan 6, which is used to filter and block residue.

[0021] In this embodiment, a push plate 5 is slidably connected to the bottom of the storage groove for pushing residue. A longitudinally arranged electric push rod 9 is fixedly connected to the back of the push plate 5 for moving the push plate 5. The end of the electric push rod 9 away from the push plate 5 passes through the lower mold base 1. The electric push rod 9 and the lower mold base 1 are fixedly connected. Two fixing rings are fixedly sleeved on the electric push rod 9 to improve the firmness between the electric push rod 9 and the lower mold base 1 and the push plate 5. The opposite sides of the two fixing rings are fixed to the inner side wall of the storage groove and the outer side wall of the push plate 5, respectively. Two guide rods 8 are fixedly connected to the side of the push plate 5 facing the electric push rod 9 for guiding the push plate 5. The end of the guide rod 8 away from the push plate 5 slides through the lower mold base 1.

[0022] In this embodiment, the front of the lower mold base 1 is provided with an opening communicating with the storage groove. A cover plate 10 corresponding to the opening is rotatably connected to the front of the lower mold base 1 for sealing the opening. A locking screw is provided on the side of the cover plate 10 away from the lower mold base 1 for locking the cover plate 10. The cover plate 10 is fixed to the lower mold base 1 by the locking screw. A rubber pad 11 is fixedly connected to the side of the cover plate 10 facing the lower mold base 1 for improving the sealing between the cover plate 10 and the lower mold base 1. A pull ring 12 is fixedly connected to the side of the cover plate 10 away from the lower mold base 1 for conveniently pulling and unscrewing the cover plate 10 by the user.

[0023] In this embodiment, after the punching operation is completed, the residue will fall naturally into the storage tank through the discharge hole 4. At this time, the exhaust fan 6 is started to enhance the effect of the residue falling and to evacuate the air in the tank. The filter screen 7 effectively intercepts the residue and prevents it from being sucked into the exhaust fan 6, ensuring that the subsequent punching operation is not affected. When the residue needs to be cleaned, simply unscrew the locking screw and unscrew the cover plate 10 to easily clean the accumulated material in the storage tank. At the same time, start the electric push rod 9 to drive the push plate 5 to move towards the opening, which can push the residue to the opening for easy cleaning.

[0024] As described above, the exhaust fan, electric push rod, lower mold base, lower mold cavity and punching have been disclosed in the prior art or are existing mature technologies. Their working principles and internal structures are known to those skilled in the art. This application only utilizes their functions and does not improve their internal structures. Therefore, they will not be described in detail.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
