[0020] In specific implementation, the core shooting machine can automatically complete the sand filling, compaction and solidification processes. Since the traditional core shooting machine usually shoots one sand core at a time, the waiting time for solidification of the sand core is long, resulting in low efficiency of sand core production. Before using the core shooting machine, the mold for producing the sand core can be fixed on the two sets of static mold plates 9, the first movable mold plate 17 and the second movable mold plate 18. When the first mold closing cylinder 14 operates, the first movable mold plate 17 can be pushed. When the first movable mold plate 17 moves, it can slide towards the static mold plate 9 through the guide column 16. When the first movable mold plate 17 slides, it can drive a set of core ejection cylinders 19 to move. When the mold on the first movable mold plate 17 is tightly combined with the mold on the set of static mold plates 9, sand shooting can be performed inside the mold between the first movable mold plate 17 and the set of static mold plates 9 through the sand shooting cylinder 4. At this time, the first sand shooting operation can be completed. When the turnover cylinder main body 6 is started, the turnover cylinder main body 6 operates, which can drive the turnover column 7 to rotate. When the turnover column 7 rotates, it can drive the first connecting disc 8 and the second connecting disc 13 to turn. When the second connecting disc 13 turns, it can drive the rotating rod 12 to rotate through the bearing seat 11. When the turnover column 7 is turned to 180°, the second movable mold plate 18 is located above the first movable mold plate 17, so that the second mold closing cylinder 15 can be started. When the second mold closing cylinder 15 operates, the mold on the second movable mold plate 18 can be tightly combined with the mold on the other set of static mold plates 9. At this time, the second sand shooting operation can be performed. During the second sand shooting operation, the first mold closing cylinder 14 can be stopped to separate the first movable mold plate 17 from the set of static mold plates 9. After the first movable mold plate 17 and the set of static mold plates 9 are separated, the sand core can be ejected from the first movable mold plate 17 and fall on the conveyor main body 5. The sand core can be conveyed by the conveyor main body 5 without manual handling by workers. After the second sand shooting operation is completed, the turnover column 7 can be turned by 180°, so that the first movable mold plate 17 and the static mold plate 9 can continue to inject the sand core.
[0021] Referring to Figs. 1-3 It can be seen that the first movable mold plate 17 and the second movable mold plate 18 can be turned by the turnover cylinder main body 6 to inject the sand core one by one, thereby achieving the effect of double-station sand core injection. The time for the first sand core forming is used for the second sand core injection operation, thereby improving the efficiency of sand core production. At the same time, the conveyor main body 5 can reduce the work intensity of workers.
[0022] Referring to Fig. 1 and Fig. 2The front part of the base 1 is provided with a fixing frame 20, the surface of the fixing frame 20 is provided with a fixing block 21, the front part of the fixing block 21 is threadedly connected with a screw knob 22, the inside of the fixing block 21 is inserted with a plug-in block 23, the top of the plug-in block 23 is connected with a guide box 24, the inside of the guide box 24 is connected with a fixing rod 25, the outer side of the fixing rod 25 is rotationally connected with a pulley 26, and the plug-in block 23 and the fixing block 21 form a plug-in structure.
[0023] In specific implementation, the core shooting machine can efficiently produce sand core products with accurate size and smooth surface. The traditional core shooting machine is not easy to guide and convey the sand core products, and manual intervention is required, which leads to the inconvenience of conveying the sand core products. The plug-in block 23 can be inserted into the inside of the fixing block 21, and the screw knob 22 can be tightened, so that the end of the screw knob 22 can threadedly slide into the inside of the plug-in block 23, thereby fixing the plug-in block 23 and the guide box 24. When the sand core product moves to the end of the conveyor main body 5 through the conveyor main body 5, it can fall onto the pulley 26 inside the guide box 24. At this time, the sand core product can slide on the pulley 26. When the sand core product slides, the pulley 26 can rotate through the fixing rod 25. When the sand core product slides out of the inside of the guide box 24, it can fall into the specified position.
[0024] Referring to Fig. 1 and Fig. 2 It can be seen that the guide box 24 can guide and convey the sand core product on the conveyor main body 5, so that the sand core product can be guided and conveyed to the specified position without manual intervention.
[0025] In summary, when the double-station core shooting machine is used, the mold for producing sand cores can be fixed on the two groups of static mold plates 9, first dynamic mold plates 17 and second dynamic mold plates 18. When the first mold closing oil cylinder 14 operates, the first dynamic mold plate 17 can be pushed. When the first dynamic mold plate 17 moves, it can slide towards the static mold plate 9 through the guide column 16. The first dynamic mold plate 17 and the second dynamic mold plate 18 can be turned over by the turnover oil cylinder main body 6 to inject sand cores one by one, thereby achieving the effect of double-station injection of sand cores. The time for the first sand core forming is used for the second injection of sand cores, thereby improving the sand core output efficiency. The conveyor main body 5 can reduce the working intensity of workers. When the sand core product slides out of the inside of the guide box 24, it can fall into the specified position. The guide box 24 can guide and convey the sand core product on the conveyor main body 5, so that the sand core product can be guided and conveyed to the specified position without manual intervention. The contents not described in detail in the description belong to the existing technology known to those skilled in the art.
[0026] Although the utility model has been explained in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
