Description

Technical Field

[0001] The utility model relates to the technical field of roller casting, in particular to an anti-cracking roller casting mold. Background Art

[0002] Because the rollers need to withstand greater rolling forces during the rolling process, the rollers are produced by one-step casting. During production, they need to be cast through a roller casting mold and finally demolded and taken out. The roller casting mold generally includes a runner and a roller cavity.
