Cast wax molds arranges column type mold cavity, and column type mold cavity center arranges center-pole, forms cast wax pattern by column type mold cavity, and in cast wax pattern, form centre bore by center-pole, centre bore wears metal core bar.
The preparation facilities of wax pattern used in described special-shaped tubulose ceramic forming process, shaping wax pattern is column type part and its two ends spherical cap portion combining structure, and column type part and spherical cap portion center are equipped with metal core bar; The goalpost shape mold cavity matched with the column type part of shaping wax pattern, spherical cap portion, metal core bar is provided with in upper and lower two parts mould.
The preparation facilities of wax pattern used in described special-shaped tubulose ceramic forming process, injection canal is provided with road in injection straight way, injection straight way nest, injection lateral road, injection, one end of injection straight way is communicated with wax injector, the other end of injection straight way is injection straight way nest, injection straight way nest bilateral symmetry arranges injection lateral road, and injection lateral road is communicated with described goalpost shape mold cavity by road in injection.
The preparation facilities of wax pattern used in described special-shaped tubulose ceramic forming process, upper part die edge is provided with locating hole, and lower part die edge is provided with locating dowel, and upper and lower two parts mould is by locating hole and locating dowel assembly.
Advantage of the present utility model and beneficial effect are:
1, the forming principle of the utility model cast wax pattern is structure and the mode of post forming, adopts the mode of liquid wax cast shaping, and the cooling procedure of wax pattern is the process of nature exhaust bubble.So the density of cast wax pattern is higher, inner without hole or bubble.
2, adopt cast wax pattern to do the shaping wax pattern of core production, the density of shaping wax pattern is higher, not easily occurs bubble or cavitation, meets the requirement of the core needed for isostatic compaction.
3, the utility model is easy and simple to handle, and yield rate is high, is beneficial to large-scale production.
