DETAILED DESCRIPTION

[0025] The technical solutions of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments.

[0026] The components of the embodiments of the present application generally described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application.

[0027] Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present application.

[0028] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", "third" are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0029] ​​In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] like Figures 1-10 As shown, a stamping die of the present invention, which can quickly remove punching waste, includes an upper die 1 and a lower die 2, wherein a stamping material 3 is disposed between the upper die 1 and the lower die 2;

[0031] The upper mold 1 has a cavity 4 fixedly installed on its bottom side, and the lower mold 2 has a core 5 fixedly installed on its top side. The core 5 is inserted into the cavity 4 with a clearance fit. When the upper mold 1 and the lower mold 2 are closed together, the stamping material 3 is cut into product 31 and edge waste 32 through the core 5 and the cavity 4.

[0032] Several upper cutting parts 14 are fixedly installed on the outer edge of the cavity 4, and several lower cutting parts 15 are fixedly installed on the lower mold 2. When the upper mold 1 and the lower mold 2 are closed, the upper cutting parts 14 and the lower cutting parts 15 match each other and cut off the edge waste material 32.

[0033] The principle is as follows: when the upper mold 1 and the lower mold 2 are closed, the stamping material 3 can be stamped through the core 5 and the cavity 4 to produce the product 31 and the edge waste 32. At this time, the edge waste 32 is an integral structure and it is difficult to separate from the lower mold 2. Therefore, this utility model provides an upper cutting part 14 and a lower cutting part 15 at the upper mold 1 and the lower mold 2 respectively. When the mold is closed, the upper cutting part 14 and the lower cutting part 15 can match each other and cut the edge waste 32, thereby stamping and cutting off the edge waste 32, which makes it easier to separate the edge waste 32 from the lower mold 2, thereby effectively speeding up the production efficiency.

[0034] Furthermore: the upper cutting member 14 has a first right-angled side 6 formed on the side near the lower cutting member 15, and the lower cutting member 15 has a second right-angled side 7 formed on the side near the upper cutting member 14. When the first right-angled side 6 descends, it matches with the second right-angled side 7 and cuts off the edge waste 32. The first right-angled side 6 and the second right-angled side 7 can be used to cut the edge waste 32, ensuring the neatness of the cut and preventing stress concentration during cutting, thereby allowing the edge waste 32 to be cut off quickly.

[0035] Further, the lower mold 2 is formed with a plurality of waste grooves 8, which are located between the second right-angled edges 7 of the two lower cutting pieces 15 one by one; the partially cut edge waste 32 can be recycled through the waste grooves 8.

[0036] Further, the lower mold 2 is fixedly installed with a plurality of right-angled baffles 9, which are arranged outside the waste grooves 8 one by one; the cut edge waste 32 can be stably dropped into the waste grooves 8.

[0037] Further, the bottom side of the lower mold 2 is fixedly installed with a plurality of raised frames 10, and the gaps between the raised frames 10 are fixedly installed with waste outlets 11, which are arranged below the waste grooves 8 one by one; the waste outlets 11 are forwardly inclined; the edge waste 32 can be stably dropped into the waste outlets 11 for recycling.

[0038] Further, the side of the lower cutting piece 15 away from the second right-angled edge 7 is formed with an inverted bevel 12, and the lower mold 2 is formed with a plurality of inclined guide grooves 13, which are located between the inverted bevels 12 of the two lower cutting pieces 15 one by one; when cutting the edge waste 32, the inverted bevel 12 can guide the cut edge waste 32, so that part of the edge waste 32 falls into the inclined guide groove 13, and the remaining edge waste 32 falls into the waste groove 8, realizing the cutting and automatic removal of the edge waste 32, and accelerating the production efficiency of the mold.

[0039] The embodiment is not limited in shape, material, structure, etc. of the utility model in any form, any simple modification, equivalent change and modification of the above embodiment according to the technical essence of the utility model are within the protection scope of the technical scheme of the utility model.
