Problems solved by technology
[0002] Refrigerator compressors widely use cast iron to make cylinder blocks. This type of cylinder block has high rigidity, and the inertial force generated by the piston connecting rod mechanism is transmitted to the shell through the cylinder block, resulting in large noise and vibration; and due to the high density of cast iron cylinder blocks, resulting in The compressor is heavy and inconvenient to handle and transport

Embodiment Construction
[0024] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0025] Such as figure 1 As shown, a cylinder block according to a preferred embodiment of the embodiment of the present invention includes a cylinder block body, and the material of the cylinder block body is aluminum foam.
[0026] It should be noted that the cylinder block of the present invention can be any existing cylinder block, so its specific structure is not limited to the appended parts of this specification. figure 1 , with figure 1 It is only a specific structural schematic diagram of one specific embodiment, and since the specific structure of any specific existing cylinder block is prior art, it is not listed here one by one.
[0027] Based on the above-me...

The invention relates to the technical field of compressors, and discloses a cylinder base and a manufacturing method. The cylinder base is made of foamed aluminum. The manufacturing method of the cylinder base comprises the following steps that a foaming mold is heated, and the foamed aluminum is molten at the same time; molten aluminum is poured into the preheated foaming mold, and the foaming mold is placed in a constant-temperature furnace; when the temperature of the molten aluminum is stabilized to be the same as or close to the temperature of the constant-temperature furnace, metallic calcium particles are added and are stirred; a foaming agent is added and is stirred to obtain pre-foamed melt; the pre-foamed melt and the foaming mold are transferred into a vacuum tank, and the vacuum tank is vacuumized through a vacuum pump; and heat preservation and foaming are carried out for a period of time, and then cooling is carried out to form the cylinder base. According to the cylinder base and the manufacturing method, foamed aluminum is used for manufacturing the cylinder base, and the foamed aluminum has the characteristics of high strength, energy absorption, vibration attenuation and high energy absorption capacity, so that the cylinder base has sound absorption and vibration attenuation functions, and loud noise and severe vibration are avoided; and meanwhile, the foamedaluminum is light, so that the weight of the cylinder base is reduced, and the cylinder base is convenient to transfer.
Description
technical field [0001] The invention relates to the technical field of compressors, in particular to a cylinder block and a manufacturing method. Background technique [0002] Refrigerator compressors widely use cast iron to make cylinder blocks. This type of cylinder block has high rigidity, and the inertial force generated by the piston connecting rod mechanism is transmitted to the shell through the cylinder block, resulting in large noise and vibration; and due to the high density of cast iron cylinder blocks, resulting in The compressor is heavy and inconvenient to handle and transport. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a cylinder block and its manufacturing method, which can avoid generating loud noise and vibration, reduce the quality of the cylinder block, and facilitate transportation. [0004] The technical solution adopted by the present invention to solve its technical pr...
