[0002] The automobile metal casting is a metal forming object obtained by various casting methods, that is, after liquid metal prepared by smelting is poured, injected, inhaled or poured into a hot-press forming mold prepared in advance by other pouring methods, and after subsequent processing means such as polishing, an object with a certain shape, size and performance is obtained. It is widely used in various mechanical processing due to its convenient processing and fast forming speed.

[0003] The hot-press forming mechanism suitable for automobile metal casting disclosed in the publication No. CN211218222U is provided with an inner opening, a round rod and a threaded sleeve. When the operator rotates two round knobs, the top end of the round rod is separated from the inside of the threaded sleeve, and then the two threaded sleeves release the fixing effect on the two round rods. At this time, the operator can pull the connecting plate or the upper module, so that the round rod is separated from the inside of the inner opening, and then the dismounting operation of the connecting plate and the upper module is completed. It is not only simple to operate, but also short in time consumption, and can avoid the adverse effect on the production efficiency of the enterprise. However, the patent still has the following problems in the actual use process:

[0004] Although the hot-press forming mechanism suitable for automobile metal casting can make the top end of the round rod separate from the inside of the threaded sleeve by rotating two round knobs, and then make the two threaded sleeves release the fixing effect on the two round rods, at this time, the operator can pull the connecting plate or the upper module, so that the round rod is separated from the inside of the inner opening, and then the dismounting operation of the connecting plate and the upper module is completed. However, since the temperature of the mold is relatively high during the hot-press forming of the casting, the operator has the risk of being scalded when manually rotating the two round knobs, thereby affecting the operation safety of the operator.

Figure 1 Figure 11 ​As shown, first, the transverse motor 202 drives the second sprocket transmission assembly 203 and the transverse threaded rod 204 to rotate, so that the transverse threaded sleeve 205 drives the transverse limiting plate 206 and the support rod 207 to move transversely, the rotating motor 208 drives the rotating disc 209 and the longitudinal support 210 to rotate, and at the same time, the longitudinal motor 211 is started to drive the longitudinal threaded rod 212 to rotate, so that the longitudinal threaded sleeve 213 drives the electric telescopic rod 214 and the spraying pump 215 to move longitudinally, the spraying pump 215 sprays the release agent in the release machine storage box 217 through the spiral spraying hose 218 from the spraying nozzle 216, thereby being capable of spraying the inside of the bottom mold body 128 and the top mold body 133, and the electric telescopic rod 214 can adjust the height of the spraying nozzle 216, thereby realizing uniform spraying inside the bottom mold body 128 and the top mold body 133.

[0043] Secondly, the first sprocket transmission assembly 106 and the lifting rotating rod 107 are driven to rotate by the lifting motor 105, the lifting rotating rod 107 drives the bevel gear transmission assembly 108 to rotate, the bevel gear transmission assembly 108 drives the lifting threaded rod 109 to rotate, the lifting threaded sleeve 110 drives the lifting plate 111 to move up and down, the top die body 133 is driven by the lifting plate 111 to move up and down, when the top die body 133 and the bottom die body 128 are combined, the metal casting can be hot press formed, the connecting pull rope 113 on both sides of the lifting plate 111 can realize the movement of the connecting hook 114, when the bottom die body 128 needs to be disassembled, the connecting pull rope 113 is wound around the small limiting wheel 118 and the connecting hook 114 is clamped and connected with the bottom die positioning rod 125 on both sides of the bottom die mounting frame 121, when the connecting pull rope 113 is driven by the lifting plate 111 to rise, the connecting pull rope 113 drives the connecting hook 114 and the bottom die positioning rod 125 to move, when the first fixed bolt 124 is separated from the bottom die support 126, the bottom die support 126 and the bottom die body 128 can be quickly disassembled, when the top die body 133 needs to be disassembled, the top die mounting frame 129 is driven by the lifting plate 111 to move up and down, the top die body 133 moves to the top of the bottom die body 128, the top die body 133 is supported by the bottom die body 128, the connecting pull rope 113 is wound around the large limiting wheel 116 and the connecting hook 114 is clamped and connected with the top die positioning rod 132 on both sides of the top die mounting frame 129, because the diameter of the large limiting wheel 116 is large, the connecting pull rope 113 in a taut state can be wound, when the top die mounting frame 129 is driven by the lifting plate 111 to rise, the top die positioning rod 132 on both sides of the top die mounting frame 129 can be pulled away in time by the connecting hook 114, the second positioning bolt 131 is quickly separated from the top die body 133, the top die body 133 can be quickly disassembled, and the top die body 133 and the bottom die body 128 are not damaged.

[0044] Finally, when the metal casting needs to be demolded, the connecting pull rope 113 is wound outside the fixed pulley 119, and the connecting hook 114 is engaged with the mounting ring 145 on both sides of the ejection base 138. During the lifting of the lifting plate 111, the connecting pull rope 113 and the connecting hook 114 drive the ejection base 138 to lift, and the ejection base 138 drives the ejection column 139 and the buffer spring 140 to lift. The buffer spring 140 is used to buffer the metal casting, so as to separate the metal casting from the bottom mold body 128. At the same time, the cooling fan 143 in the cooling bracket 141 is used to realize the rapid heat dissipation of the bottom mold body 128 in cooperation with the heat dissipation groove 122 and the heat dissipation hole 127, so as to facilitate the demolding of the metal casting.
