Description

Technical Field

[0001] The utility model relates to the technical field of trimming machines, in particular to a casting trimming machine. Background Art

[0002] In the process of cast iron production, after the molten iron is poured into the mold, as the molten iron cools and solidifies, castings corresponding to the shape of the mold will be formed. In this process, due to the design and structure of the mold, there may be connecting edges between the castings or between the castings and the mold. These connecting edges are usually referred to as "gates", "risers" or other similar structures in foundry terminology, and this part of the connecting edges needs to be removed to ensure that the castings meet the product requirements.

[0003] Patent document CN221159359U discloses an aluminum product trimming machine, including a hydraulic rod structure. The bottom surface of the hydraulic rod structure is fixedly installed with a base mounting box. The surface of the hydraulic rod structure is fixedly connected with a sliding block structure. The surface of the sliding block structure is fixedly installed with an adjustable trimming head. The top surface of the base mounting box is fixedly installed with an adjustable fixture. The aluminum product trimming machine of the utility model is convenient to connect the hydraulic rod structure and the adjustable trimming head by setting the sliding block structure, so that the adjustable trimming head can be fixed in the card slot through the sliding block and then adjusted left and right through the sliding bar. By setting the adjustable trimming head, it is convenient to replace the cutting head. By setting the adjustable fixture, it is convenient to fix the aluminum alloy and adjust the position left and right at the same time. The clamping plate moves on the surface of the sliding rod through the sliding collar two. When fixing the aluminum alloy, the fixing rotating wheel is used to tighten and fix it, and the rubber block can protect the surface of the material.

[0004] In the above solution, the trimming machine needs to adjust the cutting head during operation, which is relatively complicated, has a low processing efficiency, and the debris generated during processing is easy to fly everywhere and pollute the environment, so there is room for optimization. Therefore, it is necessary to provide a casting trimming machine to solve the deficiencies of the prior art. Summary of the Utility Model
