Description

Technical Field

[0001] The present invention relates to the technical field of tube mold processing, and in particular to a tube mold spraying device and a use method thereof. Background Art

[0002] Centrifugal casting is a technology and method that injects liquid metal into a high-speed rotating mold, causing the molten metal to perform centrifugal motion to fill the mold and form a casting. It can be used to manufacture steel pipes, which requires the use of a tubular mold. When the pipe mold is used, a spray device is required to spray its inner wall.

[0003] The existing spraying device generally drives the spray pipe to move and extend it into the mold for rotational spraying through a rail car. However, some pipe molds are relatively long, and the spray pipe also needs to have a corresponding length to fully cover the mold. Therefore, the front end of the spray pipe is easy to fall, so that the end of the spray pipe is no longer coaxial with the pipe mold, and the distance between the spray pipe and the inner wall of the pipe mold changes, which changes the spraying force and spraying distance of the spray liquid sprayed from the spray pipe, thereby affecting the spraying effect and poor uniformity. Moreover, when spraying pipe molds of different sizes, it is necessary not only to fix the spray pipe and limit it, but also to adjust the coaxiality of the spray pipe and the pipe mold. However, the staff needs to adjust it multiple times to make the coaxiality of the two uniform, which is cumbersome to operate and reduces the spraying efficiency. Summary of the invention

[0021] S2: Then the driving motor is controlled to run, and the driving motor drives the rotating shaft to rotate when running, and the rotating roller outside the rotating shaft drives the pipe mold body in the placement rack to rotate;

[0022] When the rotating shaft rotates, the outer synchronous wheel cooperates with the synchronous belt to drive the main bevel gear to rotate, and the main bevel gear drives the threaded spray pipe to rotate through the guide bar.
