DETAILED DESCRIPTION

[0030] 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.

[0031] See also Figure 1-5 The utility model provides a technical solution: an automatic demoulding automobile stamping die, including a stamping machine 1 and an automobile accessory 5, a hydraulic rod 2 is fixedly installed on the inner side of the stamping machine 1, an upper die 3 is fixedly connected to the lower end of the hydraulic rod 2, a lower die 4 is fixedly connected to the inner side of the stamping machine 1, a demoulding structure 6 is provided on the surface of the stamping machine 1, and a collecting structure 7 is provided on the side wall of the stamping machine 1.

[0032] The specific configuration and function of the demoulding structure 6 and the collecting structure 7 are described in detail below.

[0033] like Figure 1-4 As shown, the demoulding structure 6 includes a fixing bar 64 fixedly connected to the surface of the punching machine 1, the fixing bar 64 is rotatably connected to the rotating shaft 62, the side wall of the rotating shaft 62 is fixedly connected to two gauze cloths 63, the side wall of the lower mold 4 is fixedly connected to two cone thorns 68, and the other side of the gauze cloth 63 is hooked on the surface of the two cone thorns 68. The rotating shaft 62 will drive the gauze cloth 63 to wrap, and the gauze cloth 63 will lift the auto part 5 from the inner side of the lower mold 4, and the auto part 5 will slide down along the inclined surface of the gauze cloth 63, thereby realizing the demoulding and demolding of the auto part 5.

[0034] The side wall of the rotating shaft 62 is fixedly connected with a gear 65, the side wall of the upper mold 3 is fixedly connected with a connecting plate 66, the side wall of the connecting plate 66 is slidably connected with a rack 61, and the tooth surface of the rack 61 is meshed with the tooth surface of the gear 65. After the auto parts 5 are stamped, in the process of lifting the upper mold 3, the rack 61 will move relative to the gear 65, at which time the rack 61 will drive the gear 65 to rotate, and the gear 65 will drive the rotating shaft 62 to operate. The side wall of the connecting plate 66 is glued with an elastic pad 67, and the elastic pad 67 is located between the rack 61 and the connecting plate 66. By setting the elastic pad 67, the resistance in the process of sliding the rack 61 is increased, and the stability of the rack 61 during use after the movement is further improved. The mesh cloth 63 is woven from nylon material. The mesh cloth 63 made of nylon material has good use strength and avoids tearing during use.

[0035] like Figure 1 and Figure 5 As shown, the collecting structure 7 includes a limiting plate 74 fixedly connected to the side wall of the punching machine 1, a support bar 77 is slidably connected to the surface of the limiting plate 74, a plurality of second barbed hooks 76 are fixedly connected to the side wall of the support bar 77, a plurality of first barbed hooks 75 are fixedly connected to the side wall of the punching machine 1, and a collecting bag 71 is sleeved on the surfaces of the plurality of first barbed hooks 75 and the second barbed hooks 76. The collecting bag 71 is first sleeved on the surfaces of the first barbed hooks 75 and the second barbed hooks 76 to achieve preliminary support work for the bag opening position of the collecting bag 71.

[0036] The inner thread of the support bar 77 is connected with the screw rod 72, and the screw rod 72 is rotatably connected to the inside of the punching machine 1. The screw rod 72 is driven to twist, and the driving work of the support bar 77 can be realized at this time, and the distance between the support bar 77 and the punching machine 1 will increase, thereby achieving the purpose of supporting the bag opening of the collection bag 71. The first barbed hook 75 and the second barbed hook 76 are both in a "J"-shaped structure, and the end face of the screw rod 72 is fixedly connected with a rotating block 73. When the rotating block 73 is rotated, the rotating block 73 will drive the screw rod 72 to twist.

[0037] Working principle: After stamping the auto part 5, during the process of lifting the upper mold 3, the rack 61 will move relative to the gear 65, at which time the rack 61 will drive the gear 65 to rotate, the gear 65 will drive the shaft 62 to operate, the shaft 62 will drive the gauze cloth 63 to wrap, at which time the gauze cloth 63 will lift the auto part 5 from the inner side of the lower mold 4, the auto part 5 will slide down the inclined surface of the gauze cloth 63, thereby realizing the demoulding of the auto part 5. The gauze cloth 63 made of nylon material has good use strength, which avoids tearing during use. When stamping the next auto part 5, first place the auto part 5 on the gauze cloth 63, and then press the auto part 5 to fall into the lower mold 4, and then put it down when it needs to be placed. When the lower mold 4 is lowered, the rack 61 on the sliding connecting plate 66 can be staggered with the rack 61 and the gear 65 to avoid relative movement between the lower mold 4 and the gear 65 when the upper mold 4 is lowered, which causes the mesh cloth 63 on the rotating shaft 62 to rotate loosely. By setting the elastic pad 67, the resistance in the sliding process of the rack 61 is increased, and the stability of the rack 61 during use after the movement is further improved. By sliding the rack 61 and the gear 65 to corresponding positions again, the rack 61 can drive the gear 65 normally. By setting the demoulding structure 6, this demoulding structure 6 occupies a small space, and in the process of lifting the upper mold 3, the auto part 5 stuck on the inner side of the lower mold 4 can be automatically demoulded, which improves the demoulding efficiency of the auto part 5 after stamping to a certain extent.

[0038] The collecting bag 71 is first put on the surface of the first barbed hook 75 and the second barbed hook 76, and the rotating block 73 is rotated. The rotating block 73 will drive the screw rod 72 to twist. At this time, the driving work of the support bar 77 can be realized, and the distance between the support bar 77 and the punching machine 1 will increase, thereby achieving the purpose of supporting the bag mouth of the collecting bag 71, and facilitating the collection of the automotive parts 5 after demolding. The sliding of the support bar 77 on the surface of the limiting plate 74 plays a role in limiting the moving direction of the support bar 77. By setting the collecting structure 7, the support work of the bag mouth of the collecting bag 71 is facilitated, and the collection and recycling of the automotive parts 5 after automatic demolding is further facilitated.
