Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1-10, the blade sand mold blade core mold of the utility model,
the utility model provides a blade sand mould blade core mould, which comprises an upper mould 1, a lower mould 4, a sand mould cavity 100 with a sand mould blade core 3 formed inside, and the lower mould 4; wherein the upper die 1 and the outer sleeve 2 are connected with the outer sleeve inclined matching surface 2-1 by adopting an upper die inclined matching surface 1-1, and the upper die is provided with a jet opening 1-2; the outer sleeve 2 and the lower die are connected with the lower die inclined matching surface 4-1 by an outer sleeve inclined matching surface 2-3. The sand mold blade core is provided with a blade working surface 3-5 and a blade back surface 3-6, the sand mold blade core 3 is provided with a blade core outer cavity 3-2, a blade core inner cavity 3-3 and a blade core positioning boss 3-1, wherein the blade core outer cavity 3-2 is lapped with an outer sleeve inner cavity 2-2, the blade core inner cavity 3-4 is lapped with a lower mold outer cavity 4-2, and the blade core positioning boss 3-1 is positioned in a lower mold positioning groove 4-3.
And the sand mould blade core 3 is provided with a mould opening 3-3 to ensure that the blade core is extracted from the lower mould, so that the sand mould blade core is convenient to use.
Through the cooperation of oblique joining in marriage the face, realize that the assembly of this mould can guarantee together to be concentric, and easy drawing of patterns during the heating is applicable to tectorial membrane sand technology, and the thermosetting takes shape, artifical drawing of patterns again.
The blade core positioning boss 3-1 is positioned in the lower die positioning groove 4-3 and is lapped with the outer sleeve inner cavity and the lower die inner cavity.
The utility model discloses can guarantee that complicated distortion blade working face 3-5 and the 3-6 demolding in the blade back divide two not equidirectionals, the circumference is radial promptly, guarantees that blade working face, the blade back and psammitolite separation do not interfere.
The utility model discloses be adapted to centrifugal pump impeller, lead the cast sand section mould utensil of using of shell, increase the impeller, lead the shell precision casting product and trun into sand casting product scope, improve the sand casting level of the complicated impeller of distortion, lead the shell blade, many in a mould reduce casting cost and preparation cycle.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
