[0002] Most automobiles use an internal combustion engine powered by gasoline or a storage battery providing electricity as power to run. Most of its control mechanisms are directly installed in the instrument skeleton with instruments. The main body of the skeleton is made of metal, and the surface is installed with a shell made of plastic and wood, with many empty slots reserved for installing instruments.

[0003] To ensure the integrity of the instrument skeleton, it is necessary to stamp and shape the metal sheet in one go, then take it out, and then perform treatments such as grinding and polishing on the corners. If such processing is required, a mold with a delicate inner cavity is needed. However, such previous molds often transfer raw materials or remove waste materials by a conveyor belt or even by hand, lacking an auxiliary mechanism, and the metal sheet is prone to displacement during pressing, affecting the accuracy of stamping.

[0004] Now, a new type of stamping die for an automobile instrument skeleton with an auxiliary device is proposed to solve the above problems. Content of the Utility Model

[0008] Preferably, the sliding plate can vertically lift and lower in the groove, and the shells are symmetrically arranged at the front and rear ends on the left side of the guiding frame.

[0009] Preferably, a through groove is provided below the rectangular groove, and a cross plate is welded between the two sides inside the through groove. A cavity is provided at the center inside the cross plate, and two gear discs II are respectively movably connected to both sides inside the cavity. A gear disc I is movably connected to the center inside the cavity. A motor is fixed at the center of the bottom of the cross plate. Two lead screws are longitudinally assembled on both sides inside the cavity, and a connecting plate is horizontally fixed between the bottoms of the lead screws. A lifting plate is horizontally fixed between the tops of the lead screws, and two top blocks are respectively installed on both sides of the top of the lifting plate with angle steels.

[0013] Preferably, the balls are attached to the side wall of the guide rod, and the sleeve can vertically lift along the guide rod.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: The stamping die for the automotive instrument skeleton with an auxiliary device not only realizes the auxiliary conveying of metal materials, realizes the rapid ejection of the finished skeleton, but also realizes the stable pressing of the die;

[0015] (1) By respectively and movably assembling electric roller shafts on both sides inside the sliding plate, inserting the complete metal plate horizontally into the guide frame on the right side, making the left side of the metal plate embedded in the two groups of shells, lowering the sliding plate in the corresponding grooves by the air cylinder until the electric roller shafts at the bottom contact the metal plate and extrude and reinforce the plate. After the upper die and the lower die complete stamping, slightly lift the sliding plate again, and use the rotating electric roller shafts to push away the processed waste.

[0017] (3) By sleeving a sleeve outside the guide rod, when the hydraulic cylinder uses the piston rod to vertically settle the pressing frame, the upper die below the pressing frame will be vertically pressed against the lower die in the rectangular groove under the restriction of the two sleeves and the guide rod on both sides until the metal plate is pressed into the expected instrument metal skeleton shape in the inner cavity. Only then can the pressing frame and the upper die be lifted. The presence of the balls can reduce the frictional resistance and prevent the upper die from getting stuck during the movement.

Grooves 22 are respectively provided at the front and rear ends inside the shell 3 and on the inner side of the guiding frame 12. A metal plate 13 is horizontally inserted between the guiding frame 12 and the shell 3;

[0026] The bottom of the piston rod of the hydraulic cylinder 8 is fixedly connected to the pressing frame 9. The metal plate 13 can move horizontally along the guiding frame 12 and the shell 3. The sliding plate 23 can vertically lift and lower in the groove 22. The shells 3 are symmetrically arranged at the front and rear ends on the left side of the guiding frame 12;

[0027] Specifically, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the complete metal plate 13 is horizontally inserted into the guiding frame 12 on the right side, so that the left side of the metal plate 13 is embedded in the two groups of shells 3. The air cylinder 4 lowers the sliding plate 23 in the corresponding groove 22 until the electric roller shafts 21 at the bottom contact the metal plate 13 and extrude and reinforce the plate.

[0028] Embodiment 2: A through groove 2 is provided below the rectangular groove 16. A cross plate 15 is welded between the two sides inside the through groove 2. A cavity 28 is provided at the center inside the cross plate 15. Two tooth discs two 30 are respectively movably connected to both sides inside the cavity 28. A tooth disc one 29 is movably connected to the center inside the cavity 28. A motor 27 is fixed at the center of the bottom of the cross plate 15. Two lead screws 24 are respectively longitudinally assembled on both sides inside the cavity 28. A connecting plate 26 is horizontally fixed between the bottoms of the lead screws 24. A lifting plate 25 is horizontally fixed between the tops of the lead screws 24. At both sides of the top of the lifting plate 25, top blocks 20 are installed with angle steels;
