[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] This embodiment is a splash-proof metal stamping die protection structure.

[0025] like Figure 1-4 As shown, it includes a protective component 1, a supporting limit frame 2 is arranged at the lower part of the protective component 1, and the protective component 1 includes a lower protective cover 3, a connecting arm 4, a limit ring 5, an upper protective cover 6, an extension shell 7, a slide groove 8, a rectangular ring groove 9, a guide rod 10 and a compression spring 11, and the number of the extension shell 7, the connecting arm 4, the limit ring 5, the slide groove 8, the guide rod 10 and the compression spring 11 are two groups, and the rectangular ring groove 9 is opened on the outer surface of the lower end of the upper protective cover 6.

[0026] The upper protective cover 6 is fixedly installed on the outer wall of the lower end of the external upper stamping die by fixing bolts, and the support limit frame 2 is fixedly installed on the outer wall of the upper end of the external lower stamping die by fixing bolts; two groups of slide grooves 8 are opened in the middle and upper parts of the outer surfaces of both ends of the upper protective cover 6, and two groups of extension shells 7 are fixedly installed on the upper parts of the outer surfaces of both ends of the upper protective cover 6. The guide rod 10 and the compression spring 11 are both located inside the extension shell 7; the guide rod 10 is fixedly installed in the middle part of the inner cavity of the extension shell 7, and the compression spring 11 is movably sleeved on the outer wall of the upper part of the guide rod 10, and the upper end outer surface of the compression spring 11 is connected to the upper end of the inner cavity of the extension shell 7. The two groups of connecting arms 4 are fixedly installed on the middle part of the upper ends of the outer surfaces of both ends of the lower protective cover 3, the limiting ring 5 is fixedly installed on the outer surface of one end of the connecting arm 4, and the limiting ring 5 is sleeved on the outer wall of the guide rod 10, and the lower end outer surface of the compression spring 11 is fixedly connected to the upper end outer surface of the limiting ring 5; the outer wall of the lower protective cover 3 and the rectangular ring groove 9 are slidingly connected, and the outer wall of the connecting arm 4 and the slide groove 8 are slidingly connected; the limiting ring 5 and the outer wall of the guide rod 10 are slidingly connected, and the upper end outer surface of the limiting ring 5 is elastically connected to the upper part of the inner cavity of the extension shell 7 through the compression spring 11.

[0027] It should be noted that the utility model is a splash-proof metal stamping die protection structure, the upper protective cover 6 is fixed to the outer wall of the lower end of the upper stamping die by fixing bolts, and the support limit frame 2 is fixed to the outer wall of the upper end of the lower stamping die. When the upper stamping die descends, the lower end outer surface of the lower protective cover 3 first contacts the upper end of the support limit frame 2. At this time, the lower protective cover 3 and the upper protective cover 6 are set to prevent splashing. The upper stamping die continues to descend and stamping is carried out, driving the lower protective cover 3 to slide along the rectangular ring groove 9, and the lower protective cover 3 drives the connecting arm 4 to slide along the slide groove 8. The connecting arm 4 drives the limit ring 5 to squeeze the compression spring 11 along the outer wall of the guide rod 10 to play a buffering role. When the stamping is completed, the upper stamping die rises and resets. Due to the gravity of the lower protective cover 3 and the reset action of the compression spring 11, the lower protective cover 3 is reset.
