Technical Field

[0001] The utility model relates to the technical field of centrifugal casting, in particular to a Pu centrifugal casting assembly for the barrel of a nano-grinding device. Background Technique

[0002] A nano-grinder is a new type of grinder. It uses imported high-precision double mechanical seals at both ends and can use the smallest grinding medium. In centrifugal casting, several molds are radially arranged around the central runner, and all the molds rotate around the central gate, using centrifugal force to improve filling and feeding in the casting method.

[0003] However, before the existing centrifugal casting assembly is used, it needs to be spliced. After splicing, bolts are required to limit and fix the structure. Since the number of required bolts is too large, the labor intensity increases during installation, and the installation efficiency is low. Content of the Utility Model

[0010] Preferably, the cylinder cover is provided with a groove corresponding to the plug rod, and the cross-shaped rotating frame is rotatably connected to the cylinder cover.

[0011] Preferably, the lower surface of the cross-shaped rotating frame is closely attached to the upper surface of the plug rod.

[0012] Preferably, both ends of the torsion spring are fixedly connected to the cross turntable and the fixed shell respectively, and the fixed shell is fixedly connected to the cylinder cover.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] Before the new centrifugal casting assembly is used, the inner cylinder can be sleeved inside the middle support frame so that the holes of the inner cylinder and the middle support frame are aligned. The outer sleeve is sequentially sleeved on the outer wall of the middle support frame, and the holes of the outer sleeve are aligned with the holes of the middle support frame. The limiting rod is inserted into the holes of the outer sleeve, the middle support frame and the inner cylinder. The cross turntable is rotated a certain distance, and the insertion rod is inserted into the groove of the cylinder cover so that the limiting ring closely adheres to the outer wall of the connecting rod.
