Abstract
The invention relates to a method for making a resin sand low-pressure casting type matrix clear. The method comprises the following steps: firstly, manufacturing a mold plate, a model and a type matrix core head respectively; then, combining the manufactured mold plate, model and type matrix core head to form a forming mold; secondly, arranging a sand box on the forming mold and automatically filling self-hardening sand into the sand box; carrying out curing treatment on the self-hardening sand, and forming a forming cavity after the self-hardening sand is cured; meanwhile, automatically producing a type matrix core head cavity; then, manufacturing a steel type matrix with the size close to the type matrix core head, and forming a groove corresponding to the type matrix in the surface of the steel type matrix; putting the steel type matrix on a type matrix core head cavity to form a model cavity; and finally, pouring. The method has the advantages that castings with clear typefaces can be manufactured.
Description
Technical field
The present invention relates to casting field, particularly a kind of resin sand low pressure casting type matrix method clearly
.
Background technology
In sand mold low pressure casting, many product clients need, on foundry goods, the version number etc. of the material of foundry goods, foundry goods figure number and heat treatment requirements, product is cast in a certain position of workpiece.As shown in Figure 1 and Figure 2, wherein 1 is model template, and 2 is models, and 3 is type matrixes, and 4 is sandboxes in traditional production, and 5 is the die cavities after the demoulding, and 6 is sand mold fonts, and between model template and model, screw is fixed, and type matrix is positioned on model; Sandbox is positioned on model template, fills out resin self-setting sand, and after the solidification of 1 hour, produce mold cavities as shown in Figure 2, Fig. 2 medium sand type-word body is naturally shaping, because font is less, clear not.In above-mentioned technique, due to when adopting the font molding of sand casting sand casting, fill type time easily damage and cause font smudgy, must paint on some sand mo(u)ld word, also to spend and much manually clear up, to the last font that still casts out or smudgy.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of resin sand low pressure casting type matrix method clearly, and the font that casts out can be made clear.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of resin sand low pressure casting type matrix method clearly, and its innovative point is: described step is:
A) first, produce template, model and type matrix core print respectively, then, then the template made, model and type matrix core print are combined into styling representation mock;
B) secondly, sandbox is arranged on styling representation mock, in sandbox, fills self-hardening sand simultaneously, and process is cured to self-hardening sand, a mold cavities can be formed after its solidification, automatically create type matrix core print die cavity simultaneously;
C) then, produce the steel stamp that size is close with type matrix core print, on the surface of steel stamp, there is the groove corresponding with type matrix, and this steel stamp is positioned on type matrix core print die cavity, material is thus formed mould form;
D) last, pour into a mould.
Further, in described step b, the time of solidification is 1 hour-1.5 hours.
Further, in described step c, fix by casting to stick with glue to tie between steel stamp and type matrix core print die cavity.
Further, in described step c, before steel stamp being positioned over type matrix core print die cavity, need carry out preheat process to steel stamp, heating-up temperature, at 150 DEG C-160 DEG C, after preheat process, sprays chill coating on the surface of steel stamp.
The invention has the advantages that: utilize this method carrying out in the process of casting, the font mould that original sand is cast now is changed to steel stamp, by such method, font foundry goods clearly can be cast out.
Before steel stamp puts into type matrix core print die cavity, preheat process is carried out to steel stamp, spray chill coating simultaneously, font can be made more clear.

Detailed description of the invention
Resin sand low pressure casting type matrix in the present invention clearly method its realized by following step:
The first step, as shown in Figure 3, produces template 14, model 13 and type matrix core print 8 respectively, then, then the template 14 made, model 13 and type matrix core print 8 is combined into styling representation mock.
Second step, as shown in Figure 4, sandbox 15 is arranged on styling representation mock in a first step, in sandbox 15, fill self-hardening sand 7 simultaneously, and process is cured to self-hardening sand 7, the time of solidification is 1 hour-1.5 hours, can form a mold cavities 9 after self-hardening sand 7 solidifies, and automatically creates type matrix core print die cavity 10 simultaneously.
3rd step, as shown in Figure 5, produce the steel stamp 11 that size is close with type matrix core print, on the surface of steel stamp 11, there is the groove corresponding with type matrix, and preheat process is carried out to steel stamp, heating-up temperature is at 150 DEG C-160 DEG C, after preheat process, chill coating is sprayed on the surface of steel stamp, then, this steel stamp 11 is positioned on type matrix core print die cavity 10, as shown in Figure 6, fixing by casting to stick with glue to tie between steel stamp 11 and type matrix core print die cavity 10, material is thus formed mould form.In the present embodiment, before steel stamp puts into type matrix core print die cavity, preheat process is carried out to steel stamp, spray chill coating simultaneously, font can be made more clear.
4th step, pours into a mould, and forms foundry goods.
When being cast by said method, by original sand cast font mould now change to steel stamp, by such method, thus castable go out font workpiece clearly.
The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
