Technical Field
[0001] The utility model relates to the technical field of casting sand boxes, and particularly relates to a casting sand box for steel castings. Background Technique
[0002] Cast steel is a kind of steel specifically used for manufacturing steel castings. When the strength requirement of the casting is relatively high and cast iron cannot meet it, cast steel will be used. A steel casting is a part made of cast steel, whose performance is similar to that of cast iron but has better strength. Pouring refers to the process of injecting molten metal, concrete and other materials into a mold, which is used for the casting of metal parts or the forming of cement boards and concrete buildings. A casting sand box for steel castings is a device used for the production of steel castings. It mainly consists of a casting sand box body, with a casting groove opened inside and a reinforcing frame fixed outside.
[0003] A casting sand box for steel castings will be very heavy after pouring. Usually, the whole sand box needs to be turned over and lifted for demoulding. Generally, large and medium-sized ones will be lifted and moved by a lifting machine, and small ones will be moved by workers. However, in some cases, it is often impossible to use a lifting machine for moving. For example, in a narrow workshop, the lifting machine cannot enter the workshop to lift a casting sand box for steel castings. Therefore, workers can only carry it with the help of a large number of external auxiliary tools, which is not only time-consuming and laborious, but also has certain safety risks during the movement, thus affecting the work efficiency to a certain extent. Therefore, for the improvement of the existing casting sand box for steel castings, it is particularly important to design a new type of casting sand box for steel castings to solve the above technical defects and improve the overall practicability of the casting sand box for steel castings.

A first motor is provided inside the first motor housing 2. The driving end of the first motor inside the first motor housing 2 is threadedly connected to the connecting block 13 at the end of the main body 1 away from the lifting box 3. A second motor housing 5 is provided inside the top seat 6 at the top of the first rotating wheel 51. A second motor is provided inside the second motor housing 5. The driving end of the second motor inside the second motor housing 5 is fixedly connected to the first rotating wheel 51. A rotating groove 31 is opened at the end of the lifting box 3 close to the main body 1. A limiting plate 32 is slidably connected to the inside of the rotating groove 31.

When this casting sand box for steel castings is put into use, the two main bodies 1 are respectively placed on the two bottom plates 14 to prevent the molten steel from leaking during pouring. The two main bodies 1 are stacked up and fixedly connected by multiple groups of fixed blocks 11 and two bolts 12. Pouring is completed inside the main body 1. One connecting block 13 of the bottom main body 1 is threadedly connected to the driving end of the first motor inside the first motor housing 2. The other connecting block 13 of the bottom main body 1 is threadedly connected to the end of the connecting rod 4 away from the lifting box 3. The power is turned on.
