DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 4 A vertical line casting mold for ductile iron elbow castings, comprising a workbench 1, the upper end of the workbench 1 is fixedly connected to two side plates 2, and the upper ends of the two side plates 2 are commonly fixedly connected to a top plate 3;

[0023] Among them, it also includes a casting mold mechanism, which includes two telescopic rods 4 installed on the upper end of the top plate 3, both of which are hydraulic telescopic rods, and the telescopic ends of the two telescopic rods 4 are fixedly connected to an upper mold 5. A pouring hole 6 is opened at the upper end of the upper mold 5, and the staff can put the casting material through the pouring hole 6. A lower mold 7 is arranged below the upper mold 5. The upper mold 5 cooperates with the lower mold 7. The casting of the casting can be completed by splicing the two molds. Four guide rods 8 are fixedly connected to the upper end of the lower mold 7. The upper end of each guide rod 8 passes through the upper mold 5 and the top plate 3. Each guide rod 8 is slidably connected to the upper mold 5 and the top plate 3. A limiting ring 9 is fixedly connected to each guide rod 8. The four limiting rings 9 enable the upper mold 5 to drive the lower mold 7 to move synchronously during the up and down movement;

[0024] Among them, it also includes a cooling mechanism, which is used to cool the upper mold 5 and the lower mold 7 to improve the cooling and shaping rate of the casting. The cooling mechanism includes a first connecting block 10 fixedly connected to the upper end of the workbench 1. The horizontal plane length and width of the lower mold 7 and the first connecting block 10 are the same. A cooling groove is opened at the upper end of the first connecting block 10, and the lower mold 7 cooperates with the first connecting block 10. When casting, the lower mold 7 will contact with the first connecting block 10, and the ice-water mixture in the cooling groove will cool the lower end of the lower mold 7 to a certain extent. At the same time, when the lower mold 7 is released from contact with the first connecting block 10, it is also convenient for the staff to observe the situation in the cooling groove. Circulating water is arranged in the cooling groove, and an ice isolation plate 12 is vertically fixedly connected to the inner bottom of the cooling groove. The ice isolation plate 12 cools the lower mold 7. The tank is divided into a first inner tank 11 located on the right and a second inner tank 13 located on the left. The ice isolation plate 12 can limit the ice cubes 16 in the first inner tank 11 to prevent the ice cubes 16 from melting into small pieces and entering the water pump 14, thereby affecting the use of the water pump 14. Ice cubes 16 are placed in the first inner tank 11, and a water pump 14 is installed on the upper end of the workbench 1. The liquid inlet pipe of the water pump 14 passes through the first connecting block 10 and extends to the inner bottom of the second inner tank 13. The liquid outlet end of the water pump 14 is connected to a hose 15. The other end of the hose 15 passes through the upper mold 5, the lower mold 7 and the first connecting block 10 and extends to the inner top of the second inner tank 13. The hose 15 is arranged in a snake shape in the upper mold 5 and the lower mold 7 (not shown), which can effectively and evenly cool the upper mold 5 and the lower mold 7.

[0025] In the utility model, before use, firstly, add appropriate circulating water into the cooling tank, place ice cubes 16 into the first inner tank 11, control the two telescopic rods 4 to drive the upper mold 5 to move downward, drive the four guide rods 8 to move downward, and drive the lower mold 7 to move downward. During the movement, the lower end of the lower mold 7 will contact the upper end of the first connecting block 10 and stop moving downward. The upper mold 5 will still keep moving downward and finally be assembled with the lower mold 7. At this time, the casting material can be put into the space between the upper mold 5 and the lower mold 7 through the pouring hole 6. After the putting is completed, the water pump 14 is started. The circulating water in the cooling tank is continuously cooled and cooled down along the path of the hose 15 by the water pump 14. Then the circulating water will finally return to the cooling tank and mix with the ice-water mixture in the cooling tank, so that the cooling and shaping rate of the casting can be effectively accelerated.

[0026] After the casting is completely shaped, the two telescopic rods 4 are controlled to drive the upper mold 5 to move up so that the upper mold 5 and the lower mold 7 are released from splicing. At this time, the staff can recover the shaped casting, and then continue to control the two telescopic rods 4 to drive the upper mold 5 to move up. During the movement, the upper end of the upper mold 5 will contact the four limit rings 9 and drive the four guide rods 8 to move up, thereby driving the lower mold 7 to move up, so that the lower mold 7 will be released from contact with the first connecting block 10. At this time, the staff can observe the condition of the ice cube 16 in the first inner groove 11. If the ice cube 16 is about to melt or has completely melted, the staff can replace the ice cube 16 or the circulating water according to the actual situation. If most of the ice cube 16 is still unmelted, there is no need to replace it. In this way, the staff can timely understand the temperature of the circulating water according to the melting condition of the ice cube 16 and make quick adjustments. The overall operation is convenient and fast.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
