Description
Technical field
The utility model relates to a kind of mould, particularly a kind of graphite type mould.Belong to the Composite Preparation field.
Background technology
In recent years, various electromagnetism phase detachment techniques have obtained extensive studies in the application aspect preparation gradient, the composite surface material, its essence is and utilize the difference between looks and alloy liquid electrical conductivity in the alloy liquid, extra electric field, magnetic field (or both combinations) back have just formed the gradient self-generating/composite surface material of surface enrichment from the looks particle to producing electromagnetic force from looks and making it to the migration of alloy liquid superficial layer after alloy liquid solidifies in casting mold.Wherein, employing adds coil-induced alternating magnetic field mode cylindric melt is applied alternating magnetic field, the electromagnetic force that produces can make spontaneous skew wherein poly-to the melt outer surface, and by selecting suitable electromagnetic force operational factors, thereby prepare pole shape and tubulose gradient composites that primary silicon strengthens outer surface mutually, but the single hole casting mold is adopted in former experiments research, at every turn can only moulding one, efficient is too low, has influenced this technology applying in actual production.
Adopt the multi-hole casting of honeycomb can make full use of the induced field action space, improve the production efficiency of gradient composites.The multi-hole casting of honeycomb with mullite or cordierite as main material, by slurry extruding and high temperature sintering moulding.Find by literature search, " 600 holes/in2 honeycomb ceramic carrier mold for extruding and forming " (" pottery " that Deng Chong rather delivers, 2001,04) introduced 600 holes/in2 honeycomb ceramic carrier mold for extruding and forming, adopt the multi-hole casting of the honeycomb of this mould preparation, hole density can reach 600-900 hole/square inch, but, its complex technical process, essential dedicated extruded equipment and agglomerating plant, be difficult for making the porous ceramics of large aperture (more than the diameter 5mm) and circular hole, and the ceramic-mould collapsibility of preparation is poor, can not recycle, therefore be not suitable as the casting mold mould that electromagnetic separation prepares gradient composites.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art and defective, a kind of graphite type mould is proposed, make it be used for making large aperture, many circular holes gypsum mould, its technology simple and feasible, good, the recyclable utilization of gypsum mould collapsibility of making, mainly be used on the electromagnetism separator of preparation gradient composites, can improve the efficient of preparation pole shape gradient composites, thereby make electromagnetic separation prepare the requirement that this technology of gradient function composite reaches production application.
The utility model is achieved through the following technical solutions, the utility model graphite type mould comprises: some pole shape paraffin cores, top cover, metal mold and base, its connected mode is: metal mold is arranged between top cover and the base, top cover is provided with some diameters through hole and a plug hole consistent with pole shape paraffin core external diameter, base is provided with diameter and the consistent blind hole of pole shape paraffin core external diameter, by these holes pole shape paraffin core is fixed in the metal mold die cavity.The internal diameter maximum of metal mold can reach 300mm, and according to the needs of preparation bar length and diameter, the length of metal mold is chosen in the scope of 30-300mm, and the diameter of paraffin core is chosen in the scope of 3-50mm.Length range, the number of through hole and blind hole are 7-70.
In the utility model mould, metal mold is the cylinder (can separate vertically during the demoulding) of two semicircles watt formation, and top cover and base respectively have 7-70 through hole and blind hole.Assembly jig before the casting, earlier up with the base blind hole, on put metal mold and top cover, top cover, metal mold and base form the die cavity of a sealing, then pole shape paraffin core are fixed on top cover and the base one to one between the through hole and blind hole, keep vertical.After set of molds installs, gypsum, binding agent mixed slurry are poured into die cavity from the plug hole of top cover, get final product curing molding after 3-10 minute.Gypsum mould leaves standstill certain hour after solidifying, and takes off top cover, metal mold and base successively gypsum mould is deviate from, and in baking oven the fusing of paraffin core is just formed 7-70 axial through hole on gypsum mould.
The utility model is simple in structure, casting molding process simple and feasible, production efficiency height, utilizes the graphite casting mold of the utility model preparation to have cylindrical exterior, wherein is evenly distributed with the circular hole of a plurality of axial perforations, everywhere the wall thickness unanimity.Be applicable to that electromagnetic separation prepares the cast of pole in-situ graded composite, can convenient for assembly and dismounting in the electromagnetism separator.
