Abstract
The invention discloses a method for machining single-hole filling ports of automatic filling molds for magnetic shoes made of permanent-magnetic ferrites. The method includes drilling circular filling holes in a hard alloy mold sleeve matrix by the aid of a drilling machine according to required positions; machining only one kidney-shaped filling port in a side edge of each piece of hard alloy by the aid of an electric punch mode; inlaying the pieces of hard alloy in the alloy mold sleeve matrix by the aid of a heating interference mode; assuredly aligning the symmetric centers of the kidney-shaped filling ports with the circle centers of the circular filling holes. The circular filling holes are perforated through the mold sleeve matrix. The method has the advantages that slurry is filled from the corresponding circular filling hole into each mold cavity via the single corresponding kidney-shaped filling port, namely a single-hole filling mode, so that the slurry is prevented from being mixed in the cavities when filled into the adjacent mold cavities; the single kidney-shaped filling port is formed in each piece of hard alloy, so that damage to the strength of the alloy can be reduced; the common drilling machine is utilized in machining procedures, and a linear cutting machine tool can be omitted, so that the manufacturing costs of the molds can be reduced.
Description
Technical field
The present invention relates to the mould of permanent ferrite wet pressure magnetic tile, especially for the technology of sintered-carbide die sprue.
Technical background
Permanent ferrite magnetic tile is to make the mould of shaping according to the shape of magnetic shoe and ferritic shrinkage character, compression molding, minute hand charge mould, automatic-feeding mould.Hand charge mould is that the mode of filler is by hand reinforced to mould cavity, and shaping efficiency is lower.Automatic-feeding mould is the blas by hydraulic press, and slip injects each die cavity automatically, and shaping efficiency is higher.
Automatic-feeding magnetic shoe mould is in die cavity wall, to open sprue according to magnetic shoe thickness, and during moulding, punch and die cavity do relative motion, and die cavity ejects, and exposes sprue, by slip casting machine, provides power, and pulp flow, through material feeding pipelines at different levels, finally injects die cavity from sprue.Because slip has stronger mobility, from sprue adverse current feed back, sprue is processed into the mounting hole of flat conventionally when preventing moulding.
Current known automatic-feeding magnetic tile by wet pressing mould sprue processing is first with spark-erosion perforating machine, to beat the wire hole that diameter is very little in die cavity wall, then with electric spark linear cutting machine, wears the material hole of molybdenum filament processing required form.Because the machining tool of wire cutting machine is molybdenum filament, the feature of its work is that molybdenum filament motion is fixing linear, and workpiece moves along X, Y-axis by the program of setting.Therefore when processing material hole molybdenum filament through whole die cavity, the corresponding both sides of die cavity wall can respectively process a material hole, material hole of mould material feeding actual needs, another one has just become fabrication hole, and adjacent like this die cavity communicates with each other, during material feeding because slip flows mutually, affect green body quality, and affect the intensity of mould alloy, while easily causing moulding, alloy pressurized breaks, mold damage.
Summary of the invention
The object of this invention is to provide a kind of processing method that meets permanent ferrite wet pressure magnetic tile automatic-feeding alloy mold single hole sprue.
Technical scheme of the present invention is:
A processing method for permanent ferrite magnetic tile automatic-feeding mould single hole sprue, includes following operating procedure:
Mould drawing requirement in foundation, first on carbide alloy die sleeve matrix, rule and determine the position of sprue, with drilling machine, bore the circular material hole that drawing needs again, run through the spark eroding machined of die sleeve matrix, concrete operations are, first of tungsten copper, make the positive electrode of the kidney-shaped sprue of mould drawing requirement size, clamping is on electric discharge machine, by the mode of electric shock, at a side of alloy, process a kidney-shaped sprue, then adopt the mode of alloy die sleeve matrix heating is embedded in alloy in golden die sleeve matrix, when inlaying, note the symmetrical centre of the kidney-shaped sprue of processing on alloy to be right against the center of circle of the circular material hole of processing on alloy die sleeve matrix, last all the other positions of other required processing that process by drawing.
Described circular material hole, through die sleeve matrix, is processed before die sleeve matrix at carbide mosaic.
A kidney-shaped sprue of one side processing of described carbide alloy, does positive electrode processing by spark eroding mechanism, before carbide mosaic, processes.
The circular material hole of the described die sleeve matrix center of circle is right against kidney-shaped sprue symmetrical centre.
Slip of the present invention is from circular material hole, through a kidney-shaped sprue, injects die cavity, i.e. single hole material feeding, and slip string chamber while having avoided adjacent die cavity material feeding, and an alloy kidney-shaped sprue only, reduced the destruction of alloy intensity.Process common driller, avoids using wire cutting machine tool, has reduced Mold Making cost.
