Description

Technical Field

[0001] The utility model relates to the technical field of steelmaking auxiliary equipment, in particular to a mold for ladle casting. Background Art

[0002] As a container for storing and transporting liquid steel, the quality and performance of the ladle directly affect the quality and production safety of steel products. During the production of the ladle, a mold is required to pour the castable into the gap between the ladle shell and the mold. After the castable is cured, the mold is demoulded to complete the production of the ladle.

[0003] There are two conventional methods to solve the demoulding problem: one is to apply more oil on the outside of the mold, but the effect of this method is not ideal after on-site application; the other is to increase the size difference between the upper and lower parts of the mold, but this method will reduce the overall upper gap of the mold, making it difficult to observe the construction conditions of the lower part, and easily form honeycomb holes inside the castable due to insufficient vibration.

[0004] A Chinese patent discloses a mold for ladle casting (authorization announcement number CN215202579U). The patent technology sets the mold as an upper mold and a lower mold, and connects them to form a complete mold. In the demoulding process, the upper mold is demoulded first, and then the lower mold is demoulded after the upper mold is removed, so that the casting material is completely demoulded, reducing the contact area between the mold demoulded at a single time and the casting material on the ladle during the demoulding process. In the demoulding process of large-scale ladle casting, the resistance during the demoulding process is greatly reduced, and it is not easy to cause damage to the inside of the casting material after curing and forming, thereby improving the quality of the casted ladle formed by casting; a connecting plate is set to fix the upper mold and the lower mold together to prevent the gap between the bottom surface of the upper mold and the top surface of the lower mold, which causes the unshaped casting material to penetrate into the gap between the two during the casting process;

[0005] However, it has certain disadvantages: when fixing the upper tire mold and the lower tire mold, it is necessary to manually enter the upper tire mold and the lower tire mold to lock the bolts in the bolt holes; when separating the upper tire mold and the lower tire mold, manual operation is still required, which is not only troublesome but also laborious. Utility Model Content

[0006] The utility model aims to provide a ladle casting mold to solve the problems raised in the above background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] As a further solution of the utility model: the docking mechanism includes a mounting seat, a skateboard is movably connected inside the mounting seat, a docking rod is installed on the right surface of the skateboard, and two sliding rods are symmetrically installed on the left surface of the skateboard, a spring is installed on the outside of the sliding rod, a motor seat is installed on the left surface of the mounting seat, a motor is installed inside the motor seat, an adjusting rod is installed on the output end of the motor, and an adjusting rope is installed on the outside of the adjusting rod.

[0010] As a further solution of the utility model: a plurality of positioning holes are opened on the lower surface of the upper mold body, and a plurality of positioning rods are installed on the upper surface of the lower mold body.

[0011] As a further solution of the utility model: one end of the connecting seat is installed on one side surface of the inner side of the lower mold body, one end of the connecting block is installed on one side surface of the inner side of the upper mold body, and the connecting rod fits in the connecting hole.

[0012] As a further solution of the utility model: the mounting seat is installed on the left side surface of the connecting seat, the docking rod movably passes through the left side surface of the connecting seat, and the docking rod fits into the docking groove, the sliding rod movably passes through the mounting seat, one end of the spring is connected to the mounting seat, and the other end of the spring is connected to the slide plate, the adjustment rope movably passes through the right side surface of the motor seat and the mounting seat, and the adjustment rope is connected to the slide plate.

[0013] As a further solution of the utility model: the number of the positioning holes is equal to the number of the positioning rods, and the positioning holes fit the positioning rods.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model divides the mold into two parts, an upper mold body and a lower mold body, respectively, so that demoulding can be carried out in two times, thereby reducing the huge resistance caused by single demoulding and avoiding damage to the ladle; the connecting mechanism fixes the upper mold body and the lower mold body together, thus avoiding the castable material from penetrating into the gap between the two. When demoulding, the motor is turned on to store the adjustment rope, so that the docking rod leaves the interior of the docking groove, so that the two mold bodies can be demoulded in turn, and there is no need to manually separate the two mold bodies, thereby improving the convenience of operation.
