Description
Technical field
The utility model relates to Metal Injection Molding field, more specifically relates to a kind of shaping mould of square box blank.
Background technology
Metal Injection Molding is an emerging newly net forming technology.It is collection injection molding technology, polymer chemistry, the multidisciplinary product interpenetrating intersection such as powder metallurgy technology and Metal Material Science, utilize mould injection moldable blank and manufacture high density fast by sintering, high accuracy, high strength, the part of 3D shape complexity, more especially the techniques such as machining are utilized cannot to process or unmanageable miniature parts, Metal Injection Molding can create easily, and it is low to have cost, efficiency is high, the advantages such as uniformity is good, easy realization batch production, be described as " parts forming technique the most popular now ".
The operation in this field generally comprises the operations such as Design of Dies, injection moulding, deburring, degreasing, sintering, shaping.
Design of Dies: mainly according to shape of product and size design mould.
Injection moulding: be expelled in mold cavity by the feeding of configuration after binding agent and metal powder mixing by injection machine, then cooling forming is blank.
Deburring: moulding out generally comprises product cast parts and runner from injection machine, so when being separated with product by runner, can leave scraggly impression in junction and mouth of a river place, namely deburring is scabbled by this impression to be consistent with other position of product.
Degreasing: be that the main component in binding agent is taken off from product.
Sintering: comprise and remaining binding agent is removed, then sinter product into metalwork.
Shaping: because the product after sintering produces outstanding figure or distortion sometimes, cause product plane degree and linearity bad, cause the defective of product size, so the product needed after general sintering improves flatness and the linearity of product by shaping.
For the blank with square box body structure, if the distortion of fruit product frame expands outwardly, the size extended out on direction becomes large, then product can be shaped into by the extruding of slide block the structure and size wanted in reforming process.Such as application number is 201510093292.2, name be called a kind of Chinese invention patent application of moulded blank shaping mould disclose a kind of can in lateral the shaping mould of extruded blank.
But if the distortion of fruit product frame is inwardly shunk, the size inside contracting direction is less than normal, does not also have good way to solve this problem at present, can only scrap process to blank in this technical field.Due in actual sintered process, the distortion of product is uncontrollable, and therefore, blank shrinkage deformation becomes a bottle strength problem of the blank producing square frame structure.
