[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] Example 1
[0022] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a car engine cover forming mold, including an upper mold body 1, the bottom of the upper mold body 1 is fixedly connected to an upper mold base 2, the bottom of the upper mold base 2 is provided with a pressing block 3, the bottom of the upper mold body 1 is provided with a lower mold body 4, the top of the lower mold body 4 is fixedly connected to a lower mold base 5, the outer surface of the upper mold base 2 is provided with a first movable groove 12, the inner wall of the first movable groove 12 is engaged and movably connected with the outer surface of a movable rod sleeve 15, and the inner wall of the first movable groove 12 is provided with a second movable groove 13, The inner wall of the second movable groove 13 is engaged and movably connected with the outer surface of the movable rod 14, the outer surface of the pressing block 3 is fixedly connected with the movable rod 14, the outer surface of the movable rod 14 is fixedly connected with the movable rod sleeve 15, the inner wall of the movable rod sleeve 15 is fixedly connected with the inner wall of the upper mold base 2 through the second spring 16, the outer surface of the movable rod 14 is fixedly connected with the inner wall of the upper mold base 2 through the inner wall of the movable rod sleeve 15, the inner wall of the movable rod sleeve 15 is fixedly connected with the second spring 16, and the top of the second spring 16 is fixedly connected to the bottom of the first movable groove 12.
[0023] In this embodiment, by designing the pressing block 3, a pressure is applied to the surface of the alloy plate in advance when the upper die seat 2 is pressed down. With the same downward force, the smaller the area, the greater the pressure generated. There are four pressing blocks 3, which are respectively located at the four vertex corners of the upper die seat 2, so that pressure is applied to the outer circle of the surface of the alloy plate at the same time, and the position of the alloy plate is fixed in advance by local pressure to prevent the overall pressure when the upper die seat 2 is pressed down from shifting the alloy plate. The surface of the pressing block 3 has an anti-slip layer to make the pressure conversion rate higher. In order to prevent the pressing block 3 from affecting the pressing of the upper die seat 2, a first movable groove 12 is opened on the surface of the upper die seat 2 to connect with the outer surface of the movable rod sleeve 15. The surface is engaged and movably connected, and a second movable groove 13 is provided at the bottom of the inner wall of the first movable groove 12, which is engaged and movably connected with the outer surface of the movable rod 14, and the two ends of the second spring 16 are respectively fixedly connected to the inner wall of the movable rod sleeve 15 and the bottom inner wall of the first movable groove 12. In this design, when the pressing block 3 contacts the alloy plate, the second spring 16 contracts under the pressure of the upper die seat 2, and the movable rod sleeve 15 moves on the inner wall of the first movable groove 12, and the movable rod 14 moves on the inner wall of the second movable groove 13, so that when the pressing block 3 applies pressure to the alloy plate, it can shrink inside the two movable grooves when the upper die seat 2 contacts the alloy plate, thereby not affecting the use of the upper die seat 2.
[0024] Example 2
[0025] like Figure 2 As shown, the outer surface of the lower die base 5 is fixedly connected to a support 6, the outer surface of the support 6 is movably connected to a rotating rod 7 via a through hole, the outer surface of the rotating rod 7 is movably connected to a pressure plate 8, the outer surface of the pressure plate 8 is fixedly connected to a boss 9, the outer surface of the pressure plate 8 is fixedly connected to a first spring 10, the bottom of the first spring 10 is fixedly connected to a base 11, and the outer surface of the base 11 is fixedly connected to the outer surface of the lower die base 5.
[0026] In this embodiment, a support 6 is provided on the outer surface of the lower die base 5 to support the pressure plate 8 to rotate on one side. A boss 9 is provided on the outer surface of the pressure plate 8, and the alloy plate is placed on the upper end of the boss 9. The rear side of the pressure plate 8 is fixedly connected to the first spring 10, and the bottom of the first spring 10 is fixedly connected to the base 11, which is convenient for supporting the pressure plate 8 and the boss 9, thereby supporting the alloy plate. The above-mentioned structures are provided at four places so that the alloy plate can be placed stably. Since the surface of the boss 9 has a slippery surface, when pressure is applied to the alloy plate, the boss 9 and the pressure plate 8 squeeze the first spring 10 to contract, and the boss 9 rotates around the rotating rod 7 to the side of the lower die base 5, supporting the alloy plate while preventing it from affecting the stamping forming of the alloy plate.
[0027] Working principle:
[0028] like Figure 1-Figure 5As shown, when in use, the alloy plate is placed on the upper end of the boss 9, and when the upper die seat 2 is pressed down, the pressing block 3 contacts the alloy plate, and the second spring 16 contracts under the pressure of the upper die seat 2, and the movable rod sleeve 15 moves on the inner wall of the first movable groove 12, and the movable rod 14 moves on the inner wall of the second movable groove 13. When the pressing block 3 applies pressure to the alloy plate, it can be contracted inside the two movable grooves when the upper die seat 2 contacts the alloy plate. While pressing down, the boss 9 and the pressure plate 8 squeeze the first spring 10 to contract, and the boss 9 rotates around the rotating rod 7 to the side of the lower die seat 5, and the alloy plate can be formed once.
