Abstract

The invention discloses a front cover of a car air conditioner compressor FS170C and a casting method of the front cover. An extrusion casting process is adopted and mainly comprises the following steps of: melting, closing a mould, feeding, injecting, extruding, opening the mould, ejecting, taking a product and spraying. The degassing and deslagging process in a melting step comprises the concrete sub-steps as follows: when a molten aluminum temperature is 690-730 DEG C, pressing a degassing agent into a position with a distance of 10-20cm from the bottom of a crucible, and mixing until no bubbles come up; and standing for 5-12min, adding a deslagging agent, and when the molten aluminum temperature is 680-700 DEG C, preparing to close the mould. Before the mould closing step, a demoulding agent needs to be sprayed to the surface of the mould; dwell time is 6-10s and injection time is 5-9s in an injecting step; and a temperature of a mould temperature controller is 220-240 DEG C in the extruding step. The front cover of the car air conditioner compressor FS170C cast by the casting method has the advantages of compact cast structure, refined grains and high mechanical performance; and a leakage problem of the front cover of the car air conditioner compressor FS170C is better solved.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy squeeze casting production, in particular to a FS170C front cover of an automobile air-conditioning compressor and a casting method thereof. Background technique [0002] Automobile air-conditioning compressor is the heart of automobile air-conditioning refrigeration system, which plays the role of compressing and transporting refrigerant vapor. The front cover of the automobile air-conditioning compressor FS170C has a circular structure, and the front part is a stepped cylinder with a circular opening for leading out the main shaft; there are front cover screw holes on both sides of the circular sealing end surface at the rear of the front cover; the front cover is from It is a vertical surface from bottom to top, and there are 4 raised ribs on the side wall of the inner cavity on average. The bottom of each rib is connected to the sealing end surface of the front cover. The periphery of t...
