The specific embodiment
Contrast accompanying drawing below, by the description to optimum embodiment, the specific embodiment of the present utility model is described in further detail.
As shown in Figures 1 and 2, this metal pattern covers sand molding template, for core shooting before cast ball cast, cover sand molding, by template body 1, product model 2, branching block model 7, feeding head model 5, shunting running channel 6 and venting plug 4, formed, this metal pattern covers sand molding template and is fixed on special tooling by the alignment pin 3 being located on template body 1, and template body 1 is provided with dowel hole.
On template body 1, magnitude setting is 2 above feeding head models 5, and feeding head model 5 is designed to bore column, and feeding head model 5 is that upper end is with the cylinder of tapering; Feeding head model 5 numbers of connection are more than 3 or 3 cast ball or cast segment product model 2, form a moulding by casting unit.
The shape design of branching block model 7, shunting running channel 6, feeding head model 5, object is to be convenient to the demoulding.
This metal pattern covers in the shuttering work process of sand molding, is constantly heated, and its temperature is controlled within the specific limits, can realize like this injecting the molding sand Fast Heating curing molding between template body 1 and mould.
For in core shooting moment, between template body 1 and mould, exist certain gas to hinder the complete stamp of molding sand, there is covering sand imperfection, sand as scarce in part or part are covered layer of sand and are occurred cellular, directly sand Forming Quality is covered in impact, cause local occur " dross " of cast article outward appearance, occur the problem of defective work.Scheme that the present invention solves is to have inlayed quantity more than the venting plug 4 of 3 at template body 1 working face, and the moment exhaust while improving core shooting has ensured the quality of device for sand coated iron mould moulding, has avoided sand-covering technique to do over again, and has saved simultaneously and has covered sand molding grit consuming amount.
As shown in Figures 4 and 5, moment exhaust when solving core shooting better, the technical scheme that the present invention takes is:
1) venting plug 4 materials are hot good conductor, as casting zinc-copper, 40 chromium, aluminium alloy etc.;
2) on venting plug, establish air discharge duct 15, the width of air discharge duct 15 is 0.15 ~ 0.5 millimeter;
3) air discharge duct 15 quantity are more than 3 or 3;
