Description
Technical field
The utility model relates to a kind of radiator casting mould.
Background technology
Hot investment casting, belongs to Special Processes of Metal Castings.With the part that the method obtains, generally do not need to carry out again machined.As model casting, compression casting etc.Hot investment casting is a kind of casting method for traditional casting technique.It can obtain relatively accurate contoured and higher casting accuracy.More general way is: first according to product requirement, design and produce the mould of (can made allowance very little or not made allowance), the method casting wax with casting, obtains original wax-pattern; On wax-pattern, repeat coating and stucco operation, sclerosis shell and dry; Inner wax-pattern being melted away, is to be dewaxing again, obtains die cavity; Roasting shell is to obtain enough intensity; Pour into a mould needed metal material; Clear husky after shelling, thus high-precision finished product obtained.According to product needed or heat-treat and cold working.
The task of investment precision casting technology design is:
(1) analyze the manufacturability of casting structure;
(2) select rational process program, determine relevant casting technological parameter, draw on the basis of the above the drawing of rough casting;
(3) design pouring and riser systems, determines modular structure.
Full form casting process flow process is generally: Design of Dies, and------------shell processed (is first stained with slurry in wax inspection---group tree (wax pattern assemblies)---to repair wax to press wax (penetrating waxed wax-pattern) in mould manufacture, drench husky, be stained with again slurry, last formwork is air-dry)---------------------------------polishing---becomes product examine---, and warehouse-in essence casting production procedure can be divided into pressure wax to initial survey (blank inspection) to mill cast gate to foundry goods substantially in machined in impeller blasting with watering excellent cutting and separating in vibrations shelling in cast (pour steel in formwork) in voltinism analysis in formwork roasting in dewaxing (steam dewaxing), shell processed, cast, post processing, check.
Press wax to comprise and press wax, repair wax, organize tree.
Shell processed comprises hangs sand, hanging, air-dry.
Cast comprises roasting, voltinism analysis (polishing spectrum), pours into a mould, shakes shell, cuts cast gate, grinds cast gate.
Post processing comprises sandblast, ball blast, correction, pickling.
Check comprises wax inspection, initial survey, middle inspection, becomes product examine.
Compression casting is the development a kind of Special Processes of Metal Castings method that few nothing is cut faster in metal working process in modern age.It is by motlten metal at high-voltage high-speed retrofilling casting mold, and under high pressure crystallization and freezing forms the process of foundry goods.High-voltage high-speed is the principal character of compression casting.Conventional pressure is tens of MPas, and filling speed (ingate speed) is about 16～80 meter per seconds, and it is short that molten metal is filled the time compole of mold cavity, is about 0.01～0.2 second.Owing to producing in this way product, to have production efficiency high, operation is simple, higher grade of Casting tolerance, surface roughness is good, mechanical strength is large, can save a large amount of machining operation and equipment, the advantage such as save material, so now become an important component part in China's foundry industry.
Extrusion process is die casting machine, compression mod and the large key element of alloy three organically to be combined and the process of integrated use in addition.And metal, by the process of filling die cavity, is that the technological factors such as pressure, speed, temperature and time are obtained to unified process during die casting.Meanwhile, these technological factors influence each other again, restriction mutually, and complement each other.Only have selecting properly and adjust these factors, making it harmonious, just can achieve desired results.Therefore, in press casting procedure, not only to pay attention to the manufacturability of casting structure, the advance of compression mod, die casting machine performance and structure Optimality, the adaptability that diecasting alloys are selected and the standardization of smelting technology; More should pay attention to the important function of technological parameter to casting quality such as pressure, temperature and time.In press casting procedure, should pay attention to these parameters effectively to control.
CNC milling machine motor radiating needs heat radiator dedicated; international production method is punch forming before; also there is part model casting moulding; yet precision is not high; cause and in use have influence on motor radiating; serious meeting causes motor overheating to shut down, very unfavorable for CNC milling machine processing.
