During the aluminum alloy solution providing period, the air in the inner cavities of the upper die 4 and the lower die 5 can be discharged to the outside under the action of the air outlet pipe 10, the purpose of balancing air pressure is achieved, defects such as bubbles are avoided, in addition, during the process of pressing a casting on the top of the auxiliary block 113, the auxiliary block 113 can drive the limiting mechanism 17 to work, further the clamping rod 172 is separated from the limiting of the limiting hole 164, under the action of the telescopic rod 161 and the first spring piece 162, the scraper block 163 is ejected to the outside, and during the descending period of the following plate 8, the scraper block 163 can clean the inner wall of the air outlet pipe 10, so that the air outlet pipe 10 is prevented from being blocked by the aluminum alloy solution.
During the ascending and descending of the following plate 8, the windmill 131 can be rotated under the action of the power mechanism 12, due to the arrangement of the first air bag 123 and the second air bag 125, during the ascending and descending of the following plate 8, the rotation directions of the windmill 131 are opposite, so that two movement modes are generated between the threaded body 134 and the threaded block 135, during the ascending of the following plate 8, the engagement between the threaded body 134 and the threaded block 135 does not enable the power tooth 142 to drive the ratchet wheel 143 to rotate, but the situation that the threaded block 135 is reset occurs, during the descending of the following plate 8, the threaded block 135 moves reversely, so that the power tooth 142 and the ratchet wheel 143 are engaged, and the ratchet wheel 143 rotates.
When the ratchet 143 rotates, the connecting shaft 151 fixed in the inner cavity of the ratchet 143 can drive the straight rod 111 to rotate through the driving gear 152, the driven gear 153, the meshing barrel 154 and the meshing rod 155, and then the relative positions of the scraper blocks 163 are changed through the central rotating block 156, and the scraper blocks 163 scratch the inner wall of the air outlet pipe 10 without dead angles through the ascending and descending of the follow plate 8 for a plurality of times, so that the cleaning effect of the scraper blocks 163 on the inner wall of the air outlet pipe 10 is improved.
When the power mechanism 12 drives the transmission mechanism 13 to rotate, the transmission bevel gear piece 181, the third transmission rod 182, the rotating shaft 183, the rotating block 184 and the knocking block 185 can work, so that the knocking block 185 knocks on the surface of the lower die 5, the purpose of assisting in demolding is achieved, and the ejection effect of the ejection block 7 on the die casting is improved.
