Description
Technical field
The utility model relates to a kind of metal injection molded vacuum sintering furnace of using.
Background technology
Along with the development of modern instrument, people are complicated to different shape, and mechanical performance requires the demand of high machine components rapidly to increase; Because machined and other process have the restriction of material in process, and produce difficulty, can't produce in batches; Working (machining) efficiency is very low; And cost is expensive, can't satisfy the demand of society to high-performance, complicated shape machine components, and metal injection molded technology has solved this problem well.
Metal injection molded technology has in preparation and has special advantages aspect complicated shape, uniform formation's structure and the high performance high accuracy injection-molded product.The all available the method finished parts of any metal or alloy that can process powder.In addition, this technology can realize fully that automation works continuously, and production efficiency is high, and stock utilization almost can reach 100%.
Metal dust must add a certain amount of binding agent (big portion is a paraffin), mixing at a certain temperature then one-tenth metal feeding before injection moulding.Binding agent role in metal injection molded is quite crucial; Only after adding a certain amount of binding agent, metal-powder just can have suitable flowability, can be suitable for injection moulding; The back binding agent that is shaped plays a part again to keep article shape, till before sintering, being removed by degreasing.It is 40-60% that the content of binding agent is generally volume fraction.
Metal injection molded blank is in the vacuum-sintering densification process; Will inevitably give off a large amount of paraffin and other macromolecular material, it is not thorough that the dewaxing and sintering integrated stove ubiquity of existing vacuum is received wax, operation inconvenience; Collection wax device cleaning difficulty and cleaning are unclean, and discharging paraffin has part to get into vavuum pump.The serious contaminated problem of product, equipment and heat-insulation layer has influenced the service life and the product quality of equipment greatly.
The utility model content
The purpose of the utility model is to provide a kind of metal injection molded vacuum sintering furnace of using, and it is thorough effectively to solve existing metal injection molded back dewaxing, and paraffin steam other equipment of can entering cause device damage or influence the problem of service life of equipment.
In order to solve the problems of the technologies described above; The utility model is realized through following technical scheme: a kind of metal injection molded vacuum sintering furnace of using, comprise body of heater, and be connected with collection wax device on the said body of heater; Said collection wax device also links to each other with vavuum pump, has the fluid hole that lets paraffin flow out on the said collection wax device.
Preferably, said collection wax device is spherical; Can form bigger space, make the paraffin steam of entering that the adequate time cooling arranged.
Preferably, the outer wall of said collection wax device is a hollow-core construction, is provided with heating rod in the said outer wall, is filled with conduction oil in the said outer wall; Make the outer even Fast Heating of wall energy of collection wax device, improve heat utilization efficiency, accelerate inner paraffin and flow out, save time.
Preferably, adopt graphite-pipe to be connected between said body of heater and the collection wax device; Be difficult for bonding together with paraffin, stable and reliable for performance.
Preferably, comprise also and catch the wax device that the said wax device of catching is arranged between collection wax device and the vavuum pump; Further filter steam, prevent that paraffin steam from getting into vavuum pump.
Preferably, the said wax device of catching comprises shell, condenser pipe, said shell be cylindrical shape, the two ends of said shell are provided with movable end cover, said condenser pipe is located in the shell, an end of said shell links to each other with collection wax device, the other end of said shell links to each other with vavuum pump; Utilize condenser pipe to feed cold water, the gas of entering is cooled off fast.
Preferably, said body of heater is followed successively by sealant, zone of heating, heat-insulation layer, protective layer from inside to outside; Heating is rapid, and heat insulation effect is good, can effectively reduce heat loss.
Compared with prior art; The utility model has the advantages that: after metal injection molded, paraffin steam just can be drawn into to cool off in the collection wax device and condense, thereby has avoided paraffin steam to get into other equipment; Prolong the service life of these equipment, reduced enterprise's input cost.
