Description
Technical field
The present invention relates to a kind of die cast metal technique, particularly relate to a kind of automobile engine bracket ultra-low speed aluminum alloy die casting
Technique.
Background technology
Traditional high-pressure casting process, mainly comprises low speed injection, high speed injection and 3 stages of supercharging, during due to die casting
Aluminium alloy is injection at a high speed at cast gate, the most inevitably can be involved in air, easily form gas hole defect, make the intensity of product
Reducing, this makes traditional die casting be difficult to meet the product that requirement of strength is higher.For problem above, a kind of new ultralow ram compression
Casting process causes concern, and this method makes molten metal flow with layer flow mode, so that filling velocity is far below tradition die casting
Technique, Ultra-Low Speed die-casting technique can meet the low-porosity of engine support product, can heat treatment, high intensity etc. is special to be wanted
Asking, but in actual production, due to the reduction of injection speed, easily cause the defects such as cold shut, current mark, misrun, it is right to need
Technique is adjusted correspondingly and improves, to this end, the present invention is directed to engine case body support frame eka-aluminum alloy pressuring casting is object, enters
Go Ultra-Low Speed extrusion process technical research.
Summary of the invention
The present invention provides a kind of automobile engine bracket ultra-low speed aluminum alloy extrusion process for achieving the above object.
The technical solution used in the present invention:
A kind of automobile engine bracket ultra-low speed aluminum alloy extrusion process, its processing step is as follows:
(1) smelting furnace heats up: smelting furnace is heated to 750 DEG C, adds Al-alloy metal raw material, raw material in burner hearth
It is warming up to 670～690 DEG C；
(2) fixing mould: the mould in mould two chamber is fixed on the active and inactive mold plate of die casting machine, mould is preheated to 130
～230 DEG C, uniformly spray one layer of releasing agent, then matched moulds at mold cavity inner surface, heat and keep mold temperature；
(3) spraying apparatus is adjusted: adjust spraying apparatus so that spraying path can cover mold cavity comprehensively, adjusts simultaneously
The whole fuse position spraying time of staying is 8～10s；
(4) die casting: the raw material melted in smelting furnace is put into scoop, raw material is poured into feedstock transportation on die casting machine by scoop
In device, and the metal alterant of solid-state being put into liquid metal raw material, raw material conveying device, by feed liquid press-in die, enters
Row Ultra-Low Speed die casting, the supercharging energy storage pressure 13～14Mpa of system, penetrates pressure 33～37Mpa, die casting speed 0.4～0.6m/
S, pumping rate 3.5～3.7 circle handwheel is per second, shot time 8～10s；
(5) die sinking pickup: carrying out die sinking after die casting action, cooling water spray cooling 8～10s, extractor is by mould
Die casting takes out puts into conveyer belt output.
The foundry goods material handle thickness 45～55mm of die casting in described step (4).
Beneficial effects of the present invention: the present invention provides a kind of automobile engine bracket ultra-low speed aluminum alloy extrusion process, its
Product air holes defect can be made to reduce, meet the requirement of heat treatment, mechanical property obtains bigger raising.
