[0019] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.
[0020] like Figure 1 , 2 As shown, the hardware stamping die comprises a fixed die 1 and a movable die 2, a stamping groove 3 is provided on the top surface of the fixed die 1, a stamping block 4 is provided on the fixed die 1, the stamping block 4 is correspondingly arranged in the stamping groove 3, a finished product 5 is provided between the stamping groove 3 and the stamping block 4, an elastic material assembly 6 is provided on the fixed die 1, when the stamping block 4 is separated from the stamping groove 3, the elastic material assembly 6 drives the finished product 5 to separate from the stamping groove 3, the elastic material assembly 6 comprises an elastic material cavity 61, an elastic material rod 62 and a torsion spring 63, the elastic material cavity 61 is provided on the fixed die 1 and is connected to the bottom surface of the stamping groove 3, the elastic material rod 62 is rotatably connected in the elastic material cavity 61, the top end of the elastic material rod 62 acts on the bottom of the finished product 5, and the torsion spring 63 is coaxially connected between the rotation center of the elastic material rod 62 and the elastic material cavity 61.
[0021] like Figure 1-2 As shown, by setting the elastic material assembly 6, the torsion spring 63 is in a compressed state during stamping. After the finished product 5 is stamped, when the movable die 2 and the fixed die 1 are separated, the elastic force of the torsion spring 63 causes the finished product 5 to be separated from the stamping groove 3, so that it is convenient to take out the finished product 5 after stamping, and it is avoided that the finished product 5 remains in the stamping die after stamping, so that the finished product 5 is effectively separated from the fixed die 1, the difficulty of taking out the material is reduced, and the use effect of the stamping die is improved; after the stamping is completed, the torsion spring 63 returns to a normal state, which is convenient for subsequent stamping.
[0022] Therefore, when the fixed mold 1 and the movable mold 2 are closed, the finished product 5 has been processed and formed; when the fixed mold 1 and the movable mold 2 are separated, the torsion spring 63 drives the top end of the ejector rod 62 to eject the finished product 5, making it easier to separate the finished product 5 from the fixed mold 1.
[0023] Benru Figure 1 As shown in the embodiment, the fixed die 1 is also longitudinally provided with a side spring opening 7 located on the side of the stamping groove 3, as shown in FIG. Figure 2 As shown, a side elastic rod 8 is slidably fitted in the side elastic port 7, the top surface of the side elastic rod 8 is flush with the top surface of the fixed mold 1, and the bottom end of the side elastic rod 8 swings along the length direction of the ejection rod 62; a guide groove 9 is provided on the ejection rod 62, the bottom end of the side elastic rod 8 is located in the guide groove 9, a horizontally extending swing groove 10 is provided on the side of the guide groove 9, and a swing head 11 is provided on the side elastic rod 8, and the swing head 11 is slidably fitted in the swing groove 10.
[0024] When the fixed mold 1 is separated from the movable mold 2, the side spring rod 8 is driven to move upward by the action of the torsion spring 63. Due to the action of the torsion spring 63, the ejection rod 62 is synchronously driven to rotate upward. Through the provided swing head 11 and swing groove 10, the ejection rod 62 rotates upward while driving the swing head 11 to slide in the swing groove 10, thereby changing the longitudinal height of the swing head 11, thereby ensuring the smooth longitudinal upward movement of the side spring rod 8, thereby ejecting the part of the finished product 5 outside the stamping groove 3 through the side spring rod 8, thereby increasing the action point when the finished product 5 is ejected, and accelerating the ejection effect of the finished product 5.
[0025] In this embodiment, the stamping block 4 includes a stamping plate 12 and a stamping head 13. The stamping plate 12 is an inverted U-shaped structure. The stamping plate is slidably embedded in the middle of the movable mold 2. The top end of the stamping plate passes through the top of the movable mold. The top end of the stamping plate is higher than the top end of the movable mold. The stamping head 13 is slidably fitted between the inner ends of the stamping plate 12. The top end of the stamping head 13 is embedded in the stamping plate 12, and the bottom end of the stamping head 13 rests on the finished product 5.
[0026] like Figure 1-2 As shown, in this embodiment, a lower pressing groove 14 is opened on two opposite sides of the stamping plate 12, and a stamping spring 15 is longitudinally provided on the top surface of the lower pressing groove 14. An embedding strip 16 is provided on the stamping head 13, and the embedding strip 16 is slidably connected in the lower pressing groove 14, and the embedding strip 16 is fixedly connected to the bottom end of the stamping spring 15.
[0027] Before mold closing, the workpiece corresponding to the finished product 5 is flat, and the punch head 13 falls downward under the action of gravity, so that the punch spring 15 becomes extended, and the bottom end of the punch head 13 is lower than the bottom end of the punch plate 12; then, the punch plate 12 is driven to move toward the fixed mold 1 by external equipment. Since the top end of the punch plate 12 passes through the top of the movable mold 2, the top end of the punch plate 12 is higher than the top end of the movable mold 2, and the punch plate 12 is slidably embedded in the middle of the movable mold 2, so that the movable mold 2 moves synchronously after the punch plate 12 moves a certain distance, and the punch head 13 is against the workpiece, which is convenient for pre-pressing the workpiece through the punch head 13 in advance, thereby improving the punching effect; through the set punch spring 15, when the punch head 13 is separated from the finished product 5, the punch spring 15 will drive the punch head 13 to move upward in order to restore elasticity, thereby driving the finished product 5 to shake slightly upward, which is convenient for reducing the friction between the finished product 5 and the punching groove 3, which is conducive to material removal and has a clever structure.
[0028] All technical features in this embodiment can be freely combined according to actual needs.
[0029] The above embodiments are preferred implementation schemes of the present invention. In addition, other implementation schemes are also included. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
