Abstract
The invention relates to a moulding mould of a multistage centrifugal pump, comprising two core boxes; each core box is composed of a bottom plate and a moveable ring arranged on the bottom plate, the bottom plate of a NO.1 core box is provided with a profile part, an auxiliary blade and a core print position matched with a NO.2 core box; the bottom plate of the NO.2 core box is provided with a runner loose piece, a runner fixing plate and the core print matched with the NO.1 core box. In the manufacturing process, the runner is not manufactured in a multi-layer and multi-piece manner, so that the runner features integral core making; in addition the runner is smooth and complete and thoroughly meets requirements in the design drawing.
Description
Technical field
The present invention relates to a kind of mould, refer to a kind of mould of multistage centrifugal pump particularly.
Background technology
The single suction centrifugal multistage pump multiple centrifugal pump is boiler feedwater, oil transportation, mining water filling, control gold, mine, the big wide versatility product of chemical industry equivalent.Its inducer and impeller constitute this pump " heart " jointly.Because the shape of inducer design is peculiar, the mould manufacturing is very complicated, often runner section is adopted the polylith somatotype, because the polylith somatotype is time-consuming in the inducer production process, yield rate is low, and be difficult to guarantee the geometry and the size of design drawing, make the pump efficiency benefit low, cause problems such as national energy waste.
Summary of the invention
In view of the above, purpose of the present invention will overcome deficiency of the prior art exactly, and a kind of mould of multistage centrifugal pump is provided.
Technical scheme of the present invention is achieved in that a kind of moulding mould of multistage centrifugal pump, it comprises two core boxes, each core box is made up of the active ring on base plate and the base plate, the core print position that the base plate of a described core box is provided with profile part, back blades and cooperates with No. two core boxes; The base plate of described No. two core boxes is provided with runner loose piece, runner fixed head, and the core print position that cooperates with core box.
The invention has the advantages that: after designed two core boxes difference coremaking, two cores that make being fastened as casts in the integral core placement die cavity again becomes inducer, runner section not being divided into the polylith multilayer in manufacturing process makes, make runner section become whole coremaking, runner is smooth, complete and can satisfy the requirement of design drawing fully.The present invention simultaneously is simple in structure, coremaking convenient, has improved yield rate.
Description of drawings
Fig. 1 is the structural representation of a core box of the present invention.
Fig. 2 is No. two core box structural representations of the present invention.
The specific embodiment
See also accompanying drawing, it comprises two core boxes, and each core box is made up of the active ring 2 on base plate 1 and the base plate 1, the core print 5 that the base plate 1 of a described core box is provided with profile part, back blades 4 and cooperates with No. two core boxes; The core print position 8 that the base plate 1a of described No. two core boxes is provided with runner loose piece 6, runner fixed head 7 and cooperates with core box.After the coremaking of two core boxes difference, two cores that make are fastened as casts in the integral core placement die cavity again becomes inducer.
