Meanwhile, only one pulley 3 is arranged on the lower die base 2, so that the problems that a plurality of pulleys 3 are difficult to arrange, the structure of the die is complex, and coordination among all formed parts is difficult are avoided, and the stability of the flanging forming quality of the outer plate of the engine cover is ensured.

Regarding the installation of the side molding part 4, a side slider installation seat 42 installed on the lower die seat 2 is arranged on one side of the side molding part 4 away from the positioning male die 6, and the side molding part 4 is installed on the side slider installation seat 42 in a vertically sliding manner through the side slider 41. The lower end of the side slider 41 is provided with a side slider inclined guide plate 411, and a side slider driving part 33 which is contacted with the side slider inclined guide plate 411 and used for jacking the side slider 41 is arranged on the pulley 3 below the side slider inclined guide plate 411. Due to the interaction of the side slide inclined guide plate 411 and the side slide driving member 33, the side slide 41 can be driven to move upwards, and the side molding member 4 is controlled to move upwards.

In this embodiment, the side slider inclined guide plates 411 and the side slider driving members 33 are disposed in a plurality and one-to-one correspondence, and the side slider inclined guide plates 411 and the side slider driving members 33 are disposed in sequence along the moving direction of the pulley 3. The side face of the side edge slide block mounting seat 42 close to one side of the positioning convex die 6 is provided with a vertically arranged slide block mounting groove, and the side edge slide block 41 is slidably mounted in the slide block mounting groove. The side sliding block 41 is matched with the sliding block rotation groove, so that the stability and accuracy of the moving path of the side sliding block 41 can be ensured.

With respect to the installation of the bevel edge molding 5, the lower surface of the bevel edge molding 5 is connected with a bevel edge slider 51, and the bevel edge slider 51 is horizontally slidably installed on the upper surface of the bevel edge slider installation seat 34. The bevel edge forming part 5 is arranged on one side of the bevel edge slide block 51 close to the positioning male die 6, and a bevel edge slide block bevel guide plate 511 which is in contact with the secondary slotting tool 12 and is used for driving the bevel edge slide block 51 is vertically arranged on one side of the bevel edge slide block 51 far away from the positioning male die 6. The bevel slider 51 can be driven to translate due to the interaction of the bevel slider bevel guide 511 with the secondary slotting cutter 12, thereby controlling the translation of the bevel profile 5.

In addition, the lower part of the slider 51 is provided with an elastic element 7 for driving the slider to return. The lower part of the pulley 3 is provided with an elastic element 7 for driving the pulley to reset.
