[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides Figures 1 to 5The gravity impact hammer shown includes a base 1, and guide rods 2 are fixedly connected to the corners around the base 1. A gravity hammer 3 is movably connected to the surface of the guide rod 2. A connecting mechanism 4 for controlling the position of the gravity hammer 3 is arranged on the top of the gravity hammer 3. The gravity hammer 3 can provide a stamping effect for the mold closing, and the guide rod 2 is provided to provide a limited sliding for the gravity hammer 3. Then the gravity hammer 3 is connected to the crane through the connecting mechanism 4. The staff can control the falling of the gravity hammer 3 by controlling the connecting mechanism 4, so that the gravity hammer 3 can accurately stamp the mold closing.

[0021] The connecting mechanism 4 includes a lifting ring 41 and a control rod 42. The lifting ring 41 is installed on the top of the gravity hammer 3. One end of the control rod 42 is fixedly connected to a lifting hook 43 connected to the crane. A curved hook 44 is fixedly connected to the control rod 42 at a position relative to the lifting hook 43. The curved hook 44 is hung between the lifting ring 41. The control rod 42 is provided to facilitate operation by the staff. The lifting hook 43 is provided on the control rod 42 to be connected to the crane. At the same time, the curved hook 44 can be connected to the lifting ring 41 on the gravity hammer 3. Therefore, the staff controls the control rod 42 to press downward, so that the curved hook 44 is separated from the lifting ring 41, so that the gravity hammer 3 can fall along the guide rod 2, thereby providing an impact force for the mold closing.

[0022] The base 1 includes a bottom plate 101, and a pad 102 is fixedly connected to the surface of the bottom plate 101. The bottom end of the guide rod 2 passes through the pad 102 and is fixedly connected to the bottom plate 101. By setting the bottom plate 101 and the pad 102 in the base 1, a support effect can be provided when the gravity hammer 3 falls to punch the mold, which is convenient for placing the mold, so that the mold can be punched by the gravity hammer 3.

[0023] The top of the guide rod 2 is fixedly connected to a limiting gasket 5, and the cross-sectional area of ​​the limiting gasket 5 is larger than the cross-sectional area of ​​the guide rod 2. By setting the limiting gasket 5, a limiting effect can be provided to the top of the guide rod 2 to prevent the gravity hammer 3 from detaching from the guide rod 2.

[0024] A sliding sleeve 6 is embedded in a position on the gravity hammer 3 corresponding to the guide rod 2 , and the guide rod 2 is slidably connected to the inner cavity of the sliding sleeve 6 , so that the gravity hammer 3 can slide on the guide rod 2 .

[0025] During specific use, first connect the hook 43 in the connecting mechanism 4 to the crane, then lift the gravity hammer 3 with the help of the crane, and adjust the height of the gravity hammer 3 by the crane, so as to control the impact force required by the gravity hammer 3, and then manually press down the control rod 42 to separate the bent hook 44 fixedly connected on the control rod 42 and the hanging ring 41 on the gravity hammer 3, thereby releasing the gravity hammer 3, and then the gravity hammer 3 is guided by the guide rod 2 to transmit the impact force of the gravity hammer 3 to the mold, thereby impacting and pressing the mold together, and similarly, the crane is controlled through the hook 43 to make the bent hook 44 on the control rod 42 hook the hanging ring 41 of the gravity hammer 3 and rise again, thereby completing an impact process for the mold closing.
