Description
Technical field
The utility model is related to a kind of metal parts fast mould injection forming equipments.
Background technology
Metal Injection Molding（Metal Injection Molding, abbreviation MIM technologies）It is the U.S.
One novel newly net forming technology of Parmatech companies utility model, basic craft course is first by metal powder with having
Machine binding agent is uniformly kneaded, and injects curing molding in mold cavity with injection (mo(u)lding) machine under heating plasticizing state after granulation,
Then it will be removed with chemistry or the method for thermal decomposition into the binding agent in parison, most obtain final products through sintering densification afterwards.
Metal Injection Molding collects the multi-door subjects such as PM technique, injection molding technology, polymer chemistry in one
Body, using mold injection method come moulded blank, and by blank is sintered so as to produce high density, high-precision,
High intensity, complex-shaped metal parts.It is excellent that Metal Injection Molding has that at low cost, efficient, consistency is good etc.
Point, and it breaks through the limitation on shape of product of conventional metals stamping of powder forming technique, for some are complex-shaped, utilize machine
The other methods such as tool processing are difficult to the miniature parts manufactured, and Metal Injection Molding can be easier to make, therefore
It is referred to as " parts forming technique most popular now ".
In the prior art, Metal Injection Molding uses the metal die identical with injection-moulding plastic, this
Die quality is good, service life is long, but complicated, design and manufacture requirement are high, the production cycle is long, of high cost, is only suitable for batch
Larger part manufacture is measured, this largely constrains the application of Metal Injection Molding.
Recently as the fast development of 3D printing technique, a kind of new manufacture for being known as quick soft mode gradually develops
Get up, this technology is to produce part prototype using 3D printing, according to the size adhesive tape or glass of part prototype
Plank, plastic plate or cardboard etc. are enclosed shaping frame by glue etc., and part prototype is fixed in type frame, pours into silica gel, treats silica gel solid
Then type of dismantling after change frame is cut in half mold along parting line with knife, take out part prototype, then mold again and use viscose glue
Band ties up, so as to obtain the silica gel soft mode with cavity corresponding to part prototype, toward silica gel mold cavity in type vacuum injecting and forming machine
Bi-component resin is poured into a mould, can be obtained by required part after cured.This silica gel soft mode makes fast and convenient, at low cost, soft
Property it is high, and for part complicated, without pattern draft or with pattern draft and with deep groove, in product
It can be directly taken out after casting complete, this is that other Tool and Die Technology can not accomplish.Silica gel soft mode access times are generally more than ten
To hundreds of or so, the moulding by casting time is longer, is produced suitable for small lot.Since silica gel mould integral rigidity is low, heat conductivility
Difference and mould temperature are difficult to control, therefore silica gel mould is mainly used for the moulding by casting of bi-component resin material, and need elevated pressures
Silica gel mould can not be used at present with the injection moulding method having higher requirements to mold temperature control.
With the aggravation of market competition and the continuous development of manufacturing technology, even multi items, the small lot side of single-piece production
Formula is using increasingly extensive, and existing Metal Injection Molding can be only applied in mass production, this is just seriously limited
Application of the technology in engineering.If can be combined Metal Injection Molding with rapid die design, develop
A kind of metal powder injection molding technology available in jobbing work, to Metal Injection Molding into
The development of one step is of great significance.
