Description

Technical Field

[0001] The utility model relates to the technical field of casting machines, and in particular to a motorcycle shock absorber casting machine capable of casting molten iron on both the front and rear surfaces. Background Art

[0002] Motorcycle shock absorbers are components used to absorb road impact and vibration, and are essential to ensuring riding comfort and vehicle stability. In the production process of motorcycle shock absorbers, their shells usually need to be processed and cast using a casting machine. By pouring molten iron into the mold and cooling it, the required shock absorber shell is formed.

[0003] When using a casting machine to cast the shell of a motorcycle shock absorber, in order to ensure that the specifications of the shock absorber shell being processed meet the standards, it is usually necessary to fix the mold first. However, in real life, we can understand that the shell shapes and sizes of shock absorbers of different specifications are different. Therefore, when processing shock absorbers of different specifications, different molds are usually required for processing. However, in the existing technology, the staff usually uses multiple sets of screws to fix the mold, so that when the staff disassembles and replaces the mold, they need to use professional tools such as screwdrivers to screw multiple screws one by one. This not only makes it cumbersome for the staff to replace the mold, but also has low efficiency. At the same time, when the staff fixes the mold, they need to use multiple screws to fix it securely. However, when the staff screws the screws, some screws may not be screwed into place due to carelessness, thereby affecting the reliability of the mold after it is fixed. Utility Model Content

[0004] The utility model provides a motorcycle shock absorber casting machine capable of casting molten iron on both the front and rear sides, solving the problem in the related art that it is cumbersome for workers to replace the mold used for casting the motorcycle shock absorber shell.
