Integrated extrusion casting process and extrusion casting mold for hydraulic suspension shell

The hydraulic suspension shell integrated extrusion casting process comprises the following steps that S1, after a melting furnace is preheated to the first temperature, an aluminum alloy material is put into the melting furnace for smelting, and after the melting furnace continues to be heated to the second temperature, the temperature is kept at the second temperature; s2, after the aluminum alloy material is melted, Si, Mg, Ti and Sr are added into the melting furnace for refining treatment, and then a slag removal agent is added for slag removal; s3, an aluminum-strontium alloy modifier is added into the melting furnace for modification treatment, and after Sr is melted at the bottom of the melting furnace, inert gas is introduced for refining; s4, a mold is preheated, alloy liquid refined in the step S3 is input into a cavity of the mold, extrusion casting is conducted, and a hydraulic suspension shell casting blank is obtained; and S5, the hydraulic suspension shell blank is subjected to T6 heat treatme
