[0031] See also Figure 1 The embodiment of the present application provides a forming device 100. The forming device 100 is used to stamp a product 200 so that the edge of the product 200 is stamped into a full-circumference inverted shape (see Figure 7 The product 200 shown). It can be understood that when the product 200 is actually stamped, the entire edge of the product 200 can be stamped into a full-circle inverted shape, or part of the edge of the product 200 can be stamped into a full-circle inverted shape, for example, a quarter of the edge of the product 200 is stamped into a full-circle inverted shape, or a half of the edge of the product 200 is stamped into a full-circle inverted shape, or three quarters of the edge of the product 200 is stamped into a full-circle inverted shape. The embodiment of the present application does not make specific limitations on this, and it can be set according to actual production needs.

[0032] Please refer to Figure 1 , Figure 2 and Figure 3The molding device 100 includes an upper mold 10, a lower mold 20 arranged opposite to the upper mold 10, and a molding mechanism 30 arranged on the lower mold 20. The upper mold 10 and the lower mold 20 can be closed and opened. The upper mold 10 is used to stamp the product 200. The molding mechanism 30 is used to cooperate with the upper mold 10 and the lower mold 20 to stamp the product 200, and the stamped product 200 can be taken away from the molding device 100.

[0033] The upper mold 10 includes an upper mold core 11, and an upper mold groove 111 is formed on the side of the upper mold core 11 facing the lower mold 20 (see Figure 4 The lower die 20 includes a lower die core 21, and a lower die groove 211 is formed on the side of the lower die core 21 facing the upper die 10 (see Figure 4 ). When the upper mold 10 and the lower mold 20 are molded together, the upper mold groove 111 is connected with the lower mold groove 211 and is adapted to the shape of the molded product 200.

[0034] The molding mechanism 30 includes a reference member 31, a first slide 32, a second slide 33, and a third slide 34, all of which are movably disposed in the lower mold core 21. The first slide 32 is disposed on one side of the reference member 31, and the first slide 32 can also move closer to or farther from the reference member 31, that is, the first slide 32 can be disposed in the lower mold core 21 along the mold closing direction, and the first slide 32 can also move closer to or farther from the reference member 31, and the first slide 32 and the reference member 31 are located in the same plane. The second slide 33 is arranged on the other side of the reference member 31, and the second slide 33 is also connected to the reference member 31 in an oblique sliding manner, that is, the first slide 32 and the second slide 33 are respectively located on the adjacent two sides of the reference member 31, and the second slide 33 can be passed through the lower mold core 21 along the mold closing direction, and the second slide 33 can also slide obliquely relative to the reference member 31 to present a contracted or expanded state relative to the reference member 31. That is to say, when the second slide 33 slides obliquely toward the upper mold 10, the second slide 33 presents a contracted state relative to the reference member 31, and when the second slide 33 slides obliquely away from the upper mold 10, the second slide 33 presents an open state relative to the reference member 31 until the second slide 33 and the reference member 31 are located in the same plane. The third slide 34 is disposed between the second slide 33 and the first slide 32, and the third slide 34 is also connected to the second slide 33 in an oblique sliding manner. The end of the second slide 33 close to the third slide 34 and the third slide 34 are also connected to the first slide 32 in an oblique sliding manner. That is, the third slide 34 can be passed through the lower mold core 21 along the mold closing direction, and the third slide 34 can also slide obliquely relative to the second slide 33. When the third slide 34 and the second slide 33 are located in the same plane, the third slide 34 and the second slide 33 are also connected to each other in an oblique sliding manner. They can slide obliquely relative to the reference member 31 and the first slide 32 together, that is, when the third slide 34 slides obliquely toward the upper mold 10, the third slide 34 is in a contracted state relative to the second slide 33, and when the third slide 34 slides obliquely away from the upper mold 10, the third slide 34 is in an open state relative to the reference member 31, and when the third slide 34 slides obliquely away from the upper mold 10 to be in the same plane as the second slide 33, the third slide 34 can slide obliquely away from the upper mold 10 together with the second slide 33.

[0035] A first convex edge 321 is provided on the side of the first slide 32 away from the reference member 31, a second convex edge 331 is provided on the side of the second slide 33 away from the reference member 31, and a second convex edge 331 is provided on the side of the third slide 34 away from the reference member 31. The second convex edge 331 is arc-shaped. The first convex edge 321, the second convex edge 331 and the third convex edge 341 are used to cooperate with the upper mold core 11 and the lower mold core 21 to form a full-circle inverted shape of the molded product 200.

[0036] When the upper mold 10 and the lower mold 20 are molded together, the upper mold core 11 first presses the product 200. When the upper mold core 11 presses the product 200, the upper mold core 11 pushes the third slide 34 to slide obliquely close to the second slide 33 in sequence. When the third slide 34 and the second slide 33 are located in the same plane, the second convex edge 331 is connected to the third convex edge 341, and the upper mold core 11 pushes the third slide 34 and the second slide 33 to slide obliquely close to the first slide 32 and the reference member 31. When the third slide 34 and the second slide 33 are located in the same plane, the second convex edge 331 is connected to the third convex edge 341. 4. When the second slide 33, the first slide 32 and the reference part 31 are located in the same plane, the upper mold core 11 pushes the third slide 34, the second slide 33, the first slide 32 and the reference part 31 close to the lower mold core 21 and makes the third slide 34 away from the reference part 31, so that the first flange 321, the third flange 341 and the second flange 331 are connected and moved to the space enclosed by the upper mold groove 111 and the lower mold groove 211, so that the edge of the stamped product 200 is a fully folded shape.

[0037] In this embodiment, a group of forming mechanisms 30 is used to stamp and form a quarter of the circumference of the product 200 into a full-circumference inverted shape. In this embodiment, the number of groups of forming mechanisms 30 can be four groups, and the four groups of forming mechanisms 30 are connected end to end in sequence, and the four groups of forming mechanisms 30 are used to stamp and form the entire circumference of the product 200 into a full-circumference inverted shape. In the four groups of forming mechanisms 30, the four reference members 31 are connected together, which can be understood as the number of the reference members 31 is one, and the four reference members 31 after connection are roughly located in the middle of the lower mold core 21, and the two first slides 32 located on the same side of the reference member 31 are connected together, which can be understood as the number of the first slides 32 is two, and the two second slides 33 located on the same side of the reference member 31 are connected together, which can be understood as the number of the second slides 33 is two, and the number of the third slides 34 is four. In this way, by limiting the number of forming mechanisms 30 to four groups, the forming device 100 can stamp and form the entire circumference of the product 200 into a full-circumference inverted shape.

[0038] It can be understood that in other embodiments, the number of groups of the forming mechanism 30 can also be one group, two groups or three groups; when the number of groups of the forming mechanism 30 is one group, the forming device 100 can stamp and form any one quarter of the edge of the product 200 into a full-circle inverted shape; when the number of groups of the forming mechanism 30 is two groups, the two groups of forming mechanisms 30 can be arranged diagonally or connected on the same side, and the forming device 100 can stamp and form any two quarters of the edges of the product 200 into a full-circle inverted shape; when the number of groups of the forming mechanism 30 is three groups, the forming device 100 can stamp and form three quarters of the edges of the product 200 into a full-circle inverted shape. The embodiment of the present application does not specifically limit the number of groups of the forming mechanism 30, and it can be set according to actual production conditions.
