DETAILED DESCRIPTION

[0015] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate directions or positional relationships 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, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0016] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0017] The utility model will be further described below in conjunction with the accompanying drawings.

[0018] Please refer to Figure 1-3 The utility model discloses a waste discharge device for a hardware stamping machine tool, comprising a stamping male die 1 and a stamping female die 2. A support plate 3 is fixedly connected to a corner of one side of the stamping male die 1. A lever 4 is rotatably connected to the top of the support plate 3. A transmission rod 6 is movably connected to one end of the lever 4. An end of the transmission rod 6 away from the lever 4 is fixedly connected to a No. 1 trapezoidal block 7. A No. 2 trapezoidal block 9 is fixedly connected to a position of the No. 1 trapezoidal block 7 on one side of the stamping female die 2 relative to the No. 1 trapezoidal block 7. The inclined surface of the No. 2 trapezoidal block 9 contacts the inclined surface of the No. 1 trapezoidal block 7.

[0019] A slide 10 is fixedly connected to one side of the stamping male die 1 close to the transmission rod 6. The transmission rod 6 is slidably connected to the slide 10. Two springs 11 are fixedly connected to one end of the slide 10 close to the No. 1 trapezoidal block 7. The spring 11 is fixedly connected to the No. 1 trapezoidal block 7. When the No. 2 trapezoidal block 9 is separated as the stamping female die 2 is lifted, the No. 1 trapezoidal block 7 loses its extrusion. Under the push of the spring 11, the No. 1 trapezoidal block 7 is reset. The lever 4 is pulled by the pulling of the transmission rod 6 and the transmission of the connecting column 8, so that the lever 4 pushes the waste on the top of the stamping male die 1 away, thereby achieving the purpose of automatic cleaning. A slide groove 5 is chiseled at one end of the lever 4 close to the transmission rod 6, and a movable connecting column 8 is provided inside the slide groove 5. The bottom of the connecting column 8 is fixedly connected to the transmission rod 6. The No. 2 trapezoidal block 9 is a cylindrical structure, which is convenient for the connecting column 8 to slide and rotate in the slide groove 5.

[0020] Specifically, when the utility model is used, after the hardware is placed on the stamping male die 1, the stamping female die 2 is pushed downward by the driving device, and the No. 2 trapezoidal block 9 moves downward with the movement of the stamping female die 2. When the stamping female die 2 punches the workpiece, the No. 2 trapezoidal block 9 first contacts the No. 1 trapezoidal block 7, and the lever 4 is driven and rotated by the driving rod 6 to rotate the lever 4 to the other side of the stamping male die 1. After the stamping is completed, the two molds are separated, and the No. 2 trapezoidal block 9 loses the extrusion of the No. 1 trapezoidal block 7. Under the push of the spring 11, the No. 1 trapezoidal block 7 is reset. After pulling the driving rod 6, the lever 4 is reset, sweeping the top of the stamping male die 1 to sweep the waste away from the mold to achieve the purpose of cleaning.

[0021] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.

[0022] Other parts of the present invention not described in detail belong to the prior art and will not be described in detail here.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
