[0002] In the prior art, a press is a production tool that can apply pressure to the surface of an object. It is generally hydraulically driven and is mainly used for mold stamping. After stamping with a press, the stamped parts need to be demolded. Although most existing stamping structures are equipped with demolding components, they need to be driven by a separate driving force during operation. The driving force is manpower or independent mechanical equipment. Therefore, additional production costs are generated during stamping, and it is not convenient to collect the stamped parts uniformly after demolding, which has certain defects.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0033] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention. Embodiment 1:

[0034] A stamping structure of a press machine, in order to facilitate the demoulding of stamping parts, such as Figure 1-5As shown, it includes a base 1, an upper mold assembly, a lower mold assembly and a demoulding assembly, and the demoulding assembly includes:

[0035] The receiving frame 15 is fixed to the top outer wall of the base 1 by bolts;

[0036] T-shaped rod 18: It is slidably connected to the inner wall of the through hole opened on the surface of the accommodating frame 15, and a top plate 20 is welded on the top of the T-shaped rod 18;

[0037] Top plate 19: fixed to the outer circumferential wall of T-bar 18 by pins;

[0038] The spring 17 is sleeved on the circumferential outer wall of the T-shaped rod 18 , and the two ends of the spring 17 are respectively fixed to the top inner wall of the accommodating frame 15 and the bottom inner wall of the T-shaped rod 18 by means of clamping.

[0039] A lifting rod 14 is fixed on the surface of the upper mold assembly, and a middle ring 16 is fixed between the two lifting rods 14 by bolts.

[0040] The lower die assembly can be used to place the stamping parts that need to be stamped, and the upper die assembly can be used to move up and down to stamp the stamping parts. When the upper die assembly moves down for stamping, the middle ring 16 moves down in the vertical direction under the driving action of the two lifting rods 14. During this process, the middle ring 16 slides down, and the ejector plate 20 and the top plate 19 remain in a stationary state. When the upper die assembly is stamped after stamping and needs to move in the opposite direction, that is, move up, the middle ring 16 moves up and moves until it is in contact with the bottom surface of the top plate 19. As the middle ring 16 continues to move up, the middle ring 16 pulls the top plate 19, and the ejector plate 20 moves up synchronously to push the stamping parts in the lower die assembly upward, so as to facilitate the demolding of the stamping parts after stamping.

[0041] Furthermore, the upper mold assembly includes a bracket 2 and a hydraulic cylinder 2 4, the bracket 2 is fixed to the top outer wall of the base 1 by bolts, and the hydraulic cylinder 2 4 is fixed to the top outer wall of the bracket 2 by bolts, and the upper mold assembly also includes an upper mold body 12 fixed to the output end of the hydraulic cylinder 2 4 by bolts, and the upper mold body 12 is fixedly connected to the end of the lifting rod 14 away from the middle ring 16.

[0042] The hydraulic cylinder 24 can be used to drive the upper die body 12 to stamp the stamping parts in the lower die assembly during the downward movement. By fixedly connecting the lifting rod 14 and the upper die body 12, the intermediate ring 16 can move synchronously with the movement of the upper die body 12 to achieve demolding of the stamped parts after stamping.

[0043] Furthermore, the lower mold assembly includes a support plate 8 and a vertical rod 9, the vertical rod 9 is fixed to the top outer wall of the base 1 by bolts, and the support plate 8 is fixed to the top outer wall of the vertical rod 9 by bolts, the top outer wall of the support plate 8 is fixed with a lower mold body 13 by bolts, and the lower mold body 13 and the upper mold body 12 are used in conjunction with each other.

[0044] When the stamping part is placed in the lower die body 13, the upper die body 12 moves downward to stamp the stamping part. A through hole is provided at the center of the lower die body 13 so that the waste material after stamping by the upper die body 12 can be discharged through the through hole.

[0045] Working principle: During stamping, the stamped part is first placed in the lower die body 13, and then the hydraulic cylinder 24 is used to drive the upper die body 12 to move downward to stamp the stamped part. The waste material after stamping is discharged through the through hole at the center of the lower die body 13. After the stamping is completed, the hydraulic cylinder 24 drives the upper die body 12 to move upward. During this process, the middle ring 16 moves upward under the driving action of the lifting rod 14, and the outer diameter of the ejector plate 20 is larger than the outer diameter of the waste material, so that the ejector plate 20 lifts the stamped part after moving upward, so that the stamped part is separated from the lower die body 13 to realize the demoulding of the stamped part. Embodiment 2:

[0046] A stamping structure of a press machine, such as Figure 1-5 As shown, in order to facilitate the blanking of the stamped parts after stamping, this embodiment makes the following supplements on the basis of embodiment 1: a hydraulic cylinder 3 is fixed to the outer wall of one side of the bracket 2 by bolts, and a push plate 7 is fixed to the output end of the hydraulic cylinder 3 by bolts.

[0047] When the ejector plate 20 lifts the stamped part from the lower die body 13, the hydraulic cylinder 3 drives the push plate 7 to move horizontally to push the stamped part, so that the stamped part is separated from the ejector plate 20, thereby realizing the unloading of the stamped part.

[0048] Furthermore, a vertical plate 6 is fixed to the outer wall of the top of the base 1 by bolts, and a conveying roller 11 is rotatably connected between the two vertical plates 6, and a conveyor belt 5 is transmission-connected between the two conveying rollers 11. A driving motor 10 is fixed to the outer wall of one side of the vertical plate 6 by bolts, and the output end of the driving motor 10 and one end of one of the conveying rollers 11 are connected by a coupling.

[0049] The driving motor 10 is used to drive the conveying roller 11 to rotate, so that the conveying belt 5 can convey the stamping parts after unloading, thereby avoiding accumulation between the stamping parts. Embodiment 3:

[0050] A stamping structure of a press machine, such as Figure 6As shown, in order to prevent waste from accumulating and staying on the ejector plate 20 , a bent rod 22 is fixed to the inner wall of one side of the push plate 7 by bolts, and a release plate 21 is welded to one end of the bent rod 22 .

[0051] During the stamping process, the waste will fall onto the surface of the ejector plate 20, thereby affecting the subsequent demolding of the stamped parts by the ejector plate 20. By providing a disengagement plate 21, when the waste falls onto the surface of the ejector plate 20, the hydraulic cylinder 3 is used to drive the disengagement plate 21 to move horizontally to push the waste out of the surface of the ejector plate 20, thereby avoiding the accumulation of waste on the ejector plate 20.

[0052] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
