Description

Technical Field

[0001] The utility model belongs to the technical field of metal castings, and in particular relates to an integrated metal casting with a heat sink and a cylinder body. Background Art

[0002] Castings are metal shaped objects obtained by various casting methods, that is, the smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods, and then cooled and polished to obtain objects with a certain shape, size and performance.

[0003] At present, the existing cylinder metal castings, after assembly, the operation of the internal components will cause the cylinder to generate high temperature, so it is necessary to take into account a certain heat dissipation function. If the cooling and heat dissipation treatment is not carried out in time, it will be in a high temperature state for a long time, which will easily cause serious impact on the metal cylinder casting and reduce the service life of the cylinder. For this reason, we propose an integrated metal casting with a heat sink and a cylinder. Utility Model Content
