Example Embodiment

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0029] See Figure 1-2 , The present invention provides a technical solution: a wax mold assembly for small and medium-sized single crystal blades, including a casting system wax mold selector 1, a single crystal blade 2, a riser 3, and a water-cooled chassis wax template 5. The wax mold of the gating system includes the sprue cup wax mold 4, the top runner wax mold 7 and the bottom runner wax mold 8 that are sequentially connected by th...

Abstract

The invention discloses a tree structure of wax molds for small and medium-sized single crystal blades and a preparation method thereof, and relates to the technical field of precision casting. The tree structure of the wax mold group includes the wax mold of the gating system, the crystal selector, the single crystal blade, the riser, the wax mold of the water-cooled chassis, the sprue cup wax mold, the top sprue wax mold and the The wax mold of the bottom sprue; the crystal selector, the single crystal blade, and the riser are connected and fixed in sequence; the bottom of the wax mold of the central column tube and the wax template of the water-cooled chassis are locked by bolts; the wax template of the water-cooled chassis A crystal selector adhesive interface is evenly provided, and the lower end of the crystal selector is bonded to the water-cooled chassis wax template through the crystal selector adhesive interface. The wax model group tree can improve the quality of the wax model group in the precision casting process of small and medium-sized single crystal blades and reduce the subsequent scrapping rate caused thereby.

Description

Technical field [0001] The invention relates to the technical field of precision casting, in particular to a wax module tree structure for small and medium-sized single crystal blades and a preparation method thereof. Background technique [0002] Due to the low strength of the wax material used in the precision casting wax module tree structure, the current domestic manual splicing is mostly, with poor repeatability and low stability. The water-cooled chassis is a large flat plate structure, which is prone to deformation and other reasons. The finished modules are prone to module damage, poor quality of the mold shell, uneven water-cooled chassis of the mold shell, inaccurate positioning of the castings, poor repeatability between the modules, etc., resulting in mold shell cracks, casting breakouts and batches of single crystal precision castings. It has disadvantages such as poor inter-phase stability, poor single crystal integrity due to inclusions, and low casting qualificati...
