As a further scheme of the invention, the blowing directions of the two pairs of fans are the same side, so that the air circulation is increased, and the cooling of the aluminum liquid is accelerated.
The working principle is as follows: when the device is used, the die 23 is placed on the conveyor belt 7, then the motor 2 is started, the motor 2 rotates to drive the incomplete gear 20 to rotate, so that the incomplete gear 20 drives the U-shaped rack 11 to reciprocate, and the convex column 4-1 fixedly connected with the first limiting plate 4 is arranged in the driving groove 11-1, so that the U-shaped rack 11 drives the first limiting plate 4 to reciprocate up and down (as shown in figure 2) when reciprocating, and further drives the cylinder 5 to reciprocate up and down;
because the first limiting plate 4 on the left side is provided with teeth, the first limiting plate 4 will drive the flywheel 13 rotatably arranged in the supporting device 1 to rotate when moving up and down (as shown in fig. 2 and fig. 9), wherein the flywheel 13 can only rotate when the first limiting plate 4 moves down, when the first limiting plate 4 drives the flywheel 13 to rotate, the flywheel 13 will drive the single-tooth gear 24 fixedly connected with the flywheel through the rotating shaft to rotate, because the single-tooth gear 24 is connected with the roller shaft 7-1 through the perforated belt 21, the single-tooth gear 24 rotates to drive the conveyor belt 7 to move, so that the conveyor belt 7 conveys the mold 23 to the cylinder 5 and puts into the cylinder directly below, because the single-tooth gear 24 has only one tooth, when the single-tooth gear 24 drives the mold 23 to move to the cylinder 5 directly below, the teeth of the single-tooth gear 24 are just separated from the perforated belt 21, the single-tooth gear 24 will not drive the roller shaft 7-1 to rotate any more, at the moment, the first limit plate 4 still drives the cylinder body 5 to move downwards until the cylinder body 5 inserts the discharge port into the pouring port of the mold 23, and then the valve 17-1 in the cylinder body 5 is pushed upwards by the ejector rod arranged in the mold 23, so that the aluminum solution flows into the mold 23 along the fluid groove 5-1 when the mold 23 is static;
when the U-shaped rack 11 drives the cylinder 5 to move downwards, the driving groove 11-1 on the U-shaped rack 11 is provided with an upper straight groove section and a lower straight groove section, so that the convex column 4-1 fixedly connected to the first limiting plate 4 cannot drive the cylinder 5 to continuously move downwards when sliding in the straight groove, thereby providing time for material injection;
after the material injection is completed, the cylinder body 5 moves upwards (i.e. returns to the initial state) under the action of the return movement of the U-shaped rack 11, and the first limit plate 4 does not drive the flywheel 13 to rotate at the moment; secondly, in the process of moving the cylinder body 5 upwards, the valve 17-1 can be separated from the top column in the die 23, and the valve 17-1 can close the discharge hole again under the action of the second spring 16;
then the cylinder body 5 is driven by the U-shaped frame to do reciprocating motion again, so that the conveyor belt 7 is driven to move, and the poured mold 23 is conveyed forwards;
meanwhile, when the U-shaped rack 11 reciprocates, the U-shaped rack 11 can drive a first rack 11-2 fixedly connected with the U-shaped rack to reciprocate, when the cylinder body 5 moves downwards, the U-shaped rack 11 moves towards the front end of the conveyor belt 7, so that the first rack 11-2 is driven to move synchronously with the conveyor belt, when the cylinder body 5 moves downwards, the conveyor belt 7 moves towards the fan 8, and because a stop lever 18 is arranged in a groove formed in the conveyor belt 7, the conveyor belt 7 can drive the stop lever 18 to move reversely with the U-shaped rack 11; that is, the U-shaped rack 11 drives the conveyor belt 7 to move in the opposite direction when moving to the front end of the conveyor belt 7; therefore, the first rack 11-2 and the stop lever 18 move in opposite directions (namely, the first rack and the stop lever are away from each other), and the stop lever 18 can push the vibration device 6 to move towards the fan 8, and the first rack 11-2 moves towards the front end of the conveyor belt 7 to drive the first gear 14 to rotate, so that the first rack drives the first gear 14 meshed with the first rack to rotate, and further drives the vibration device 6 to rotate, so that the vibration device 6 knocks the bottom of the poured mold 23, bubbles generated during pouring are reduced, the quality of a product is improved, and the generation of meat deficiency and air holes is prevented;
in addition, the stop lever 18 can drive the vibration device 6 to move synchronously, so that the vibration mechanism can effectively and constantly knock the center of the bottom of the mold 23, on one hand, the problem that bubbles in the mold 23 cannot be stably eliminated due to uneven bottom knocking of the mold 23 in the knocking process is prevented, and on the other hand, the problem that the vibration device 6 and an uncooled product move relatively to cause aluminum liquid spilling possibly is prevented in the knocking process;
the stop lever 18 is connected to the limit post 18-1 in a sliding manner, the limit post 18-1 is connected to the conveying belt 7 in a sliding manner through a third spring 18-2, a section of circumference of the limit post 18-1 protruding out of the stop lever 18 is smooth and provided with an inclined plane, the middle part is provided with a second limit strip 18-4 matched with a semicircular groove in the stop lever 18, and the tail end is provided with a first limit strip 18-3 matched with a sliding groove in the conveying belt 7 (namely the tail end is connected with the conveying belt 7 in a sliding manner through the second limit strip 18-4); therefore, after the stop lever 18 drives the vibration device 6 to move for a certain distance, the limiting column 18-1 can slide towards the inner side of the conveyor belt 7 under the limitation of the second stop block 12-1 fixedly arranged on the second limiting plate 12, so that the middle part of the limiting column 18-1 moves into the conveyor belt 7 and is staggered with the stop lever 18, and the smooth section can be embedded into the stop lever 18, so that the stop lever 18 can rotate; and at this time, the vibration device 6 is pulled back to the initial position under the action of the first spring 14; the stop lever 18 can continue to move along with the conveyor belt 7 so as to restore to the vertical state under the action of gravity, and the limiting column 18-1 can restore to the initial state under the action of the third spring 18-2 after the limitation of the second stop block 12-1 is lost;
thereby completing the casting of the aluminum ingot.
