Description

Technical Field

[0001] This utility model relates to the field of stamping dies, and in particular to a stamping die. Background Technology

[0002] Metal stamping dies consist of a lower die and an upper die. When in use, the blank is placed on the lower die, and the upper die moves downward to close with the lower die, thus stamping the blank on the lower die into a certain shape.

[0003] Sometimes a slider mechanism is set in the mold. The slider mechanism is used to form local features of the product. Traditional sliders require a separate driving device, which makes the mold mechanism more complicated. Utility Model Content

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a stamping die with the advantage of high precision.

[0005] The technical solution adopted by this utility model to solve the problem is: a stamping die, comprising:

[0006] A stamping die includes an upper die base and a lower die base that are slidably connected to each other, an upper die mounted on the upper die base, and a lower die mounted on the lower die base. The upper die base is laterally slidably connected to a slider. The upper die and the upper die base are vertically movably connected. The upper die and the slider are respectively provided with a matching sliding key and a sliding groove. The lower end of the sliding groove is inclined outward.

[0007] As a further improvement to the above technical solution, a connecting column is also included. The lower end of the connecting column is fixedly connected to the upper mold. A limiting platform is provided on the upper part of the connecting column, and a step is provided on the upper mold base. The limiting platform can be hung on the step.

[0008] As a further improvement to the above technical solution, a spring is provided between the step and the limiting platform.

[0009] As a further improvement to the above technical solution, the upper mold base includes an upper template, the upper template is provided with a horizontally arranged connecting key, the slider is provided with a horizontally arranged connecting groove, and the connecting groove is slidably connected to the connecting groove.

[0010] As a further improvement to the above technical solution, the upper mold is connected to the slider on both the left and right sides.

[0011] As a further improvement to the above technical solution, the lower mold includes a central lower mold and a side lower mold. The side lower mold is fixedly connected to the lower mold base, and the central lower mold is slidably connected to the lower mold base. It also includes a hydraulic cylinder, which is drivenly connected to the central lower mold. The slider can move down to the inside of the side lower mold.

[0012] The beneficial effects of this utility model are:

[0013] 1. No separate drive structure is needed for sliding, simplifying the mold;

[0014] 2. Before stamping, the upper and lower dies can hold the blank in place, resulting in more stable subsequent forming.

[0015] 3. In this structure, the slider does not rub against the product, resulting in high product surface quality. Attached Figure Description

[0027] Reference Figures 1 to 5 A stamping die, comprising:

[0028] The upper mold base 1 and the lower mold base 4 are slidably connected to each other, the upper mold 3 is installed on the upper mold base 1, and the lower mold 5 is installed on the lower mold base 4. The upper mold base 1 is slidably connected to the slider 2 in the horizontal direction. The upper mold 3 is movably connected to the upper mold base 1 in the vertical direction. The upper mold 3 and the slider 2 are respectively provided with a matching sliding key 21 and a sliding groove 31. The lower end of the sliding groove 31 is inclined outward.

[0029] The principle of this utility model:

[0030] First, the blank is placed on the lower mold 5, and the upper mold base 1 moves downward until the upper mold 3 contacts the upper surface of the blank. (Refer to...) Figure 2 The gap between the upper mold 3 and the lower mold 5 is used to place the blank, and the mold is in a pressing state;

[0031] Then, the upper mold base 1 continues to move down while the lower mold 5 remains stationary. The blank is subjected to the pressure of the upper mold 3, the distance between the upper mold base 1 and the upper mold 3 decreases, and the slider 2 is squeezed outward by the upper mold 3 until the upper surface of the upper mold 3 contacts the upper mold base 1.

[0032] Then, the upper mold base 1, upper mold 3, and slider 2 move down as a whole, and the lower mold base 4 and lower mold 5 also move down accordingly until the mold is closed. (Refer to...) Figure 3 The mold is in the closed state.

[0033] Finally, the lower die holder 4 and lower die 5 reset, the die opens, and the product can be removed, thus completing a full stamping process. (Die opening state reference) Figure 1 .

[0034] In a preferred embodiment, a connecting column 32 is further included. The lower end of the connecting column 32 is fixedly connected to the upper mold 3. A limiting platform 321 is provided on the upper part of the connecting column 32, and a step 12 is provided on the upper mold base 1. The limiting platform 321 can be hooked onto the step 12. The connecting column 32 is used to limit the mutual distance between the upper mold 3 and the upper mold base 1. When the limiting platform 321 is hooked onto the step 12, the mutual distance between the upper mold 3 and the upper mold base 1 is at its maximum.

[0035] In a preferred embodiment, a spring 6 is provided between the step 12 and the limiting platform 321. When the upper mold base 1 moves downward and the distance between it and the upper mold 3 gradually decreases, the elastic force of the spring 6 can be applied to the blank.

[0036] In a preferred embodiment, the upper mold base 1 includes an upper template 11, on which a horizontally arranged connecting key (not shown) is provided. The slider 2 is provided with a horizontally arranged connecting groove 22, and the connecting groove and the connecting groove 22 are slidably connected. Keyway connection is one of the reliable connection methods to achieve mutual sliding between the upper template 11 and the slider 2.

[0037] In a preferred embodiment, the upper mold 3 is connected to the slider 2 on both the left and right sides.

[0038] In a preferred embodiment, the lower mold 5 includes a central lower mold 51 and a side lower mold 52. The side lower mold 52 is fixedly connected to the lower mold base 4, and the central lower mold 51 is slidably connected to the lower mold base 4. It also includes a hydraulic cylinder, which is kinetically connected to the central lower mold 51. The slider 2 can move down to the inner side of the side lower mold 52. The side lower mold 2 and the slider 2 cooperate to form a curved surface.

[0039] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
