[0011] The static pressure molding production process with the sleeve box cooling function comprises the following steps:

[0012] ① The static pressure molding casting line 1 produces the sand mold loaded in the sand box and falls to the conveying line 2 to pour molten iron, thereby obtaining the sand box loaded with the castings;

[0013] ② The sand box loaded with the castings on the pouring line 2 moves to the end in the length direction and is transferred to the one end position on the sand box cooling line 4 through the sand box transfer mechanism 3;

[0014] ③ The sand box moves on the sand box cooling line 4 to the other end of the cooling line and is transferred to the return line 5 through the sand box transfer mechanism 3;

[0015] ④ The sand box moves on the return line 5 to the first-stage box poking machine assembly, and when the sand box is located at the bottom position of the sand box grabbing and transferring mechanism 6, the sand box grabbing and transferring mechanism 6 transfers the sand box to the first box poking machine 7 pushed upward;

[0016] ⑤ The first box poking machine 7 pushes the sand and the castings in the sand box upward into the sleeve box, and the sleeve box loaded with the castings is transferred to the sleeve box conveying line 9 through the first sleeve box grabbing and transferring mechanism 8;

[0017] ⑥ The sleeve box on the sleeve box conveying line 9 moves to the end away from the first-stage box poking machine assembly and is transferred to the one end position on the sleeve box cooling line 11 through the sleeve box transfer mechanism 10;

[0018] ⑦ The sleeve box moves on the sleeve box cooling line 11 to the other end of the cooling line and is transferred to the sleeve box conveying line 9 close to the first-stage box poking machine assembly through the sleeve box transfer mechanism 10;

[0019] ⑧ The sleeve box moves on the sleeve box conveying line 9 to the second-stage box poking machine assembly, and when the sleeve box loaded with the castings is located in the second sleeve box grabbing and transferring mechanism 12, the second sleeve box grabbing and transferring mechanism 12 transfers the sleeve box to the first cleaning mechanism 13 pushed downward;

[0020] ⑨ The sleeve box located at the lower part of the first cleaning mechanism 13 falls under the action of gravity, and the castings in the sleeve box fall onto the casting conveyor 14, and after the castings fall, the first cleaning mechanism 13 sweeps the floating sand on the inner wall of the sleeve box downward to the casting conveyor 14, and the casting conveyor 14 transfers the castings to other processes, thereby completing the sand falling and part taking.

[0021] The above process steps are suitable for castings with large temperature drop requirements, which need to be cooled in the sand box cooling line 4 and the sleeve box cooling line 11 in turn. If the temperature drop requirement of the casting is small, it will reach the cooling temperature after walking in the sand box cooling line 4, so it is not necessary to move to the sleeve box cooling line 11 for cooling. In order to achieve the above purpose, the device can be suitable for castings with different temperature drop requirements, after the sand and the casting in the sand box are pushed into the sleeve box in step ⑤, the following operations are performed:

[0022] If the casting in the sleeve box needs to prolong the cooling time, the first sleeve box grabbing and transferring mechanism 8 moves the sleeve box containing the casting to the sleeve box conveying line 9 and performs subsequent cooling operation. If the casting in the sleeve box does not need to prolong the cooling time, the first sleeve box grabbing and transferring mechanism 8 moves the sleeve box containing the casting to the bottom of the second cleaning mechanism 15 at the end of the first sleeve box knocking machine assembly, and the casting in the sleeve box falls onto the casting conveying machine 14 under the action of gravity. After the casting falls, the second cleaning mechanism 15 starts to clean the floating sand on the inner wall of the sleeve box downward to the casting conveying machine 14, and the sand knockout and part taking are completed.

[0023] In order to make the arrangement of the sand box cooling line 4 and the sleeve box cooling line 11 more reasonable and not occupy extra space, which is conducive to the movement of the casting on each conveying line, the pouring line 2 and the return line 5 are arranged in the same line, and the sand box after sand knockout and part taking can enter the static pressure molding and casting line 1 to facilitate the next sand making, clamping and pouring. The sand box cooling line 4 and the sleeve box cooling line 11 are vertically layered, and the sleeve box cooling line 11 is located on the upper side of the sand box cooling line 4. The sleeve box conveying line 9 is located in the upper layer of the sleeve box knocking machine assembly, and the pouring line 2 and the return line 5 are located in the lower layer of the sleeve box knocking machine assembly. The arrangement of the two cooling lines in the upper and lower layers not only reduces the overall device area, but also ensures the length distance of the cooling line, which not only ensures the normal cooling of the casting, but also reduces the production cost.

[0024] In order to enable the gradually loaded sand box or sleeve box to move between each cooling line and conveying line, sand box moving mechanism 3 is installed between the pouring line 2 and the sand box cooling line 4, and between the return line 5 and the sand box cooling line 4. The sand box moving mechanism 3 is located at the both ends of the sand box cooling line 4 in the length direction. The sleeve box moving mechanism 10 is installed between the both ends of the sleeve box conveying line 9 and the sleeve box cooling line 11 in the length direction.

[0025] The first sleeve box knocking machine assembly crosses the return line 5, the sleeve box conveying line 9 and the casting conveying machine 14, and the first sleeve box knocking machine assembly can realize the movement of the casting between the return line 5 and the sleeve box conveying line 9 or between the return line 5 and the casting conveying machine 14. The second sleeve box knocking machine assembly crosses the sleeve box conveying line 9 and the casting conveying machine 14, and the second sleeve box knocking machine assembly can realize the movement of the casting between the sleeve box conveying line 9 and the casting conveying machine 14.

[0026] Further, in order to enable the sand box with castings to be cooled in multi-thread on the sand box cooling line 4, the sand box cooling line 4 comprises several parallel arranged conveying lines, the sand box transferring mechanism 3 can transfer the sand box to each conveying line respectively, and the sand box can be cooled in each conveying line. In order to enable the flask with castings to be cooled in multi-thread on the flask cooling line 11, the flask cooling line 11 comprises several parallel arranged conveying lines, the flask transferring mechanism 10 can transfer the flask on the flask conveying line 9 to each conveying line respectively, and the flask can be cooled in each conveying line.

[0027] The static pressure molding casting line 1 comprises a sand box part, the sand box is used to hold the sand mold and the castings, the pouring line 2 is used to pour the molten iron into the sand box after molding, and the sand box after pouring through the pouring line 2 is the sand box with castings. The sand box transferring mechanism 3 can be the existing transfer equipment, or can comprise two sand box transfer trolleys and a cooling storage mechanism, and the sand box transferring operation is realized through the cooperation of the above three devices. The return line 5 is used to transfer the sand box cooled in the cooling line to the flask ejector, and waits for the flask ejecting operation. The main function of the cleaning mechanism is to clean the floating sand on the inner wall of the flask, and has the auxiliary flask ejecting function.
