Technical Field

[0001] The utility model relates to the field of die bottom plate casting, in particular to a punching device for casting die bottom plate casting holes with a quick clamping structure. Background Technique

[0002] The bottom plate is the bottom part of the die, usually made of a hard metal material such as steel, aluminum alloy, etc. The bottom plate usually has one or more fixing holes for installing bolts or other accessories for fixing the edge of the die.

[0003] After the casting die is produced and cast into shape, a punching machine is needed to punch the casting die bottom plate. However, during the use process, the die does not fit due to the lack of pressure on the top and side, resulting in the cutting hole being different from the expectation, so the die is cut and damaged, which will waste resources and consume human resources. Content of the Utility Model

By providing the column rod 6, the mold bottom plate to be drilled can be effectively fixed, achieving a more stable drilling effect;

[0029] Referring to Figure 2 and Figure 3 , a column body 8 is fixedly connected to the bottom of the pressing plate 7. A clamping column 9 is fixedly connected to the bottom of the column body 8. The surface of the clamping column 9 is clamped and connected to the inside of the fixing groove 205.

[0031] Referring to Figure 1 andFigure 6 , a motor 18 is fixedly connected to the output end of the first hydraulic press 3. The output end of the motor 18 is fixedly connected to a fixing ring 13. An annular interface 15 is movably connected inside the fixing ring 13. A concave snap ring 16 is clamped inside the cavity of the annular interface 15. A drill bit 14 is fixedly connected to the bottom of the concave snap ring 16. By setting the clamping connection between the concave snap ring 16 and the annular interface 15, and convex snap strips are provided on the surface of the concave snap ring 16, while convex snap grooves are provided inside the annular interface 15, and the bottom of the drill bit 14 is provided with teeth, the effect of facilitating hole drilling is achieved;

[0032] Refer to Figure 6 , a stud 12 is threadedly connected to the inner cavity of the fixing ring 13. Thread grooves are provided in the inner cavities of the annular interface 15 and the concave snap ring 16, and one end of the stud 12 penetrates through the annular interface 15 and the concave snap ring 16 and is threadedly connected to the thread groove. By setting the stud 12, the annular interface 15, the concave snap ring 16 and the fixing ring 13 are efficiently fixed together. When the sizes of the holes to be cut are different, the drill bit 14 can be quickly replaced here, thereby improving the production efficiency.

[0033] Working principle: Before use, the machine should be started for preheating. First, adjust the drill bit 14 that needs to drill holes. The drill bit 14 can be replaced by the stud 12. After replacing the appropriate drill bit 14, then place the mold bottom plate on the surface of the placement plate 203. After the mold is loaded, the operator should push the handle 201. At this time, the thrust is transmitted to the fixed block 202, and the fixed block 202 further transmits the force to the convex column 204. The convex column 204 pushes the circular movable block 206, compressing the spring 207 fixed on one side. At this time, the mold bottom plate is pushed to a suitable position, and the second hydraulic press 5 is started. At this time, the output end of the second hydraulic press 5 presses the column rod 6 downward. When the column rod 6 moves downward, it will drive the pressing plate 7 to press downward. At this time, the column body 8 and the clamping column 9 installed at the bottom of the pressing plate 7 will also move downward. At this time, the surface of the clamping column 9 is mutually clamped with the surface of the fixed groove 205, and the mold can be effectively fixed. When the mold needs to be drilled, the pressing plate 7 will be pressed downward under the action of the column rod 6 and the second hydraulic press 5, thereby further fixing the mold. After the fixing is completed, the motor 18 is started, and the drill bit 14 at the output end of the motor 18 starts to rotate at a high speed to cut the mold. When the mold is drilled, the spring 207 will push the circular movable block 206, and the circular movable block 206 will transmit the force to the convex column 204 again, thereby restoring the fixed block 202 to the initial state. Then, remove the drilled mold, and then load it again, and repeat the above operations.

[0034] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements fall within the scope of the present utility model claimed.
