Description

Technical Field

[0001] The utility model relates to the technical field of cylinder sleeve processing, in particular to a cylinder sleeve mold quick-change baffle. Background Art

[0002] During the centrifugal casting process, the end face of the mold of the cylinder liner blank should be blocked with a baffle to ensure the final shape. Figure 1 (In the figure, 1 is the baffle, and 2 is the centrifugal hammer). The traditional method in the industry is to use a centrifugal hammer to press the baffle. When the mold rotates, the centrifugal force is used to press one end of the hammer against the baffle to prevent the baffle from falling during the pouring process. After the pouring is completed, the mold stops rotating and the hammer is automatically released.

[0003] For cylinder liner blanks with large cylinder diameters, the mold and baffle will be correspondingly enlarged. At the same mold speed, the shape and mass of the fly hammer must be enlarged to obtain sufficient centrifugal force to reliably press the baffle. However, this structure is unreliable and the baffle is prone to fall off, affecting the normal production of casting and posing safety hazards. Therefore, based on the above technical problems, improvements are needed. Utility Model Content
