[0024] Example 1, such as Figures 1-6 As shown, a pressure injection punch for a large die-casting machine includes a punch body 1, and an adjustment device 2 is provided on the punch body 1 for adjusting the position of the connecting components so that the punch body 1 can be easily connected to external components.

[0025] Reference Figures 4-5 As shown, in this embodiment: the connecting assembly includes an extension cylinder 201 slidably connected inside the punch body 1 and a threaded sleeve 202 fitted on its top; the adjusting device 2 includes a groove 203 formed on the top surface of the punch body 1; a sliding rod 204 is fixedly installed between the inner walls of both sides of the groove 203 and a sliding plate 205 that slides on the outer wall; a spring 206 is fixedly installed between the sliding plate 205 and one inner wall of the groove 203; an insert rod 207 is fixedly installed on the surface of the sliding plate 205; multiple insertion holes 208 are evenly formed on the outer wall surface of the extension cylinder 201; the adjusting device 2 also includes two support rods 209 fixed to the top surface of the punch body 1. The limit frame 210 is mounted on its top. A groove 211 is provided on the inner wall surface of one side of the limit frame 210 and a limit plate 212 that slides on its inner wall. A limit hole 213 is provided on the side of the limit plate 212. A through hole 214 is provided on the surface of the limit frame 210. A limit rod 215 is inserted into the limit hole 213 through the through hole 214. The external threaded sleeve 202 on the top surface of the extension cylinder 201 cooperates with the internal threaded hole 36 of the external component to make the punch body 1 stronger when connected with the external component. The position of the extension cylinder 201 can be adjusted, thereby increasing the area for the operator to hold and improving the convenience of subsequent installation.

[0026] Reference Figures 2-6As shown in this embodiment: the punch body 1 is provided with a cooling device 3 inside, the cooling device 3 includes a cooling cavity 31 opened inside the punch body 1, a liquid inlet head 32 is fixedly installed on the outer wall surface of the punch body 1, the liquid inlet head and the cooling cavity 31 are interconnected, a plug head 33 is inserted inside the liquid inlet head 32, an extension plate 34 and a bolt 35 with matching threaded connection are fixedly installed on the surface of the plug head 33, and a threaded hole 36 is opened on the end face of the liquid inlet head 32.

[0027] Working principle: When the device is needed, first pull the limiting rod 215 out of the limiting hole 213. Then, slide the sliding plate 205, causing it to move on the surface of the sliding rod 204. The movement of the sliding plate 205 on the surface of the sliding rod 204 will compress the spring 206, causing the spring 206 to be compressed. At the same time, the movement of the sliding plate 205 on the surface of the sliding rod 204 will also drive the insertion rod 207 to move. The movement of the insertion rod 207 will cause it to move out of the insertion hole 208. The insertion rod 207 and the insertion... When the hole 208 separates, the extension cylinder 201 loses its limiting position inside the punch body 1. At this point, the extension cylinder 201 can be moved. The movement of the extension cylinder 201 drives the external threaded sleeve 202 to move. When the extension cylinder 201 moves to the appropriate position, the sliding plate 205 is released, and the rebound force of the spring 206 causes the insertion rod 207 to be reinserted into the corresponding insertion hole 208, thereby limiting the position of the extension cylinder 201 at this time. Then, the limiting rod 215 is inserted into the limiting hole 213 through the through hole 214. This restricts the position of the limiting plate 212 within the slide groove 211, preventing vibration of the punch body 1 during operation that could cause the spring 206 to extend or retract, thus displacing the sliding plate 205 on the outer wall of the slide rod 204 and reducing the tightness of the insertion of the insertion rod 207 into the insertion hole 208. Then, the external threaded sleeve 202 is inserted into the internal threaded hole 36 of the external component. Rotating the extension cylinder 201 completes the connection between the punch body 1 and the external component, improving the connection strength between them. When cooling is required... When the liquid is introduced into the cooling chamber 31, first loosen the bolt 35 and unscrew the bolt 35 from the inside of the threaded hole 36. The separation of the bolt 35 and the threaded hole 36 causes the plug 33 to lose its restraint inside the liquid inlet head 32. At this time, the plug 33 can be pulled out from the inside of the liquid inlet head 32. Then, the coolant is introduced into the inside of the liquid inlet head 32 and then enters the inside of the cooling chamber 31 from the inside of the liquid inlet head 32 to cool down the high temperature generated by the punch body 1 during operation, and further improve the service life of the punch body 1.
