Abstract
The utility model discloses a casting tool for a herringbone impeller. The casting tool comprises a circular disc; a plurality of blades are uniformly distributed on the circular disc along the circumferential direction of the circular disc; each blade is arranged along the radial direction of the circular disc; the blades are partitioned by regular rib plates; and one side of the center of the circular disc is provided with a pouring gate, and the other side of the center of the circular disc is provided with a core print. The blades are uniform in thickness, a runner is uniform and smooth, and blockage is avoided; a blade model is easy to manufacture, the number of model tools is small, and a device for positioning left and right blade mud cores is not needed to be considered; and the model tools are machined by a machine tool, complex and irregular shapes which can be realized by manual operation are changed to be regular shapes which can be processed by the machine tool, model accuracy is improved by the machining accuracy of the machine tool, and the complexity of the manufacturing and maintenance processes of the model and the cost are reduced.
Description
Technical field
The utility model belongs to herringbone impeller casting field, is specifically related to a kind of casting frock of herringbone impeller.
Background technology
Impeller is the core component of pump, is equivalent to the heart of pump, and the impeller shape of all kinds of pumps is also different, has also formed quite ripe casting frock according to different impeller shapes.In the pump industry, traditional casting frock of herringbone blade impeller is respectively to do a loam core with the both sides blade passage, again with this two loam core clogs " V " shape loam core, becomes disc set to be combined into the impeller loam core in these 20 bonding loam cores again." V " shape angle when two loam cores are bonding about the bad control of this casting frock, two positions are not easy alignment up and down, and its runner face fineness is relatively poor, inefficiency; And the harvest rate of product and quality can only rely on workman's experience height.
Summary of the invention
The utility model technical problem to be solved is the deficiency to above-mentioned prior art, and a kind of casting frock of herringbone impeller is provided, and it can improve production efficiency of products and the quality that guarantees product.
The technical scheme that the utility model adopted is: a kind of casting frock of herringbone impeller; It comprises a disk; Said disk circumferentially is evenly distributed with several pieces blades along it, and every blade is along the radially setting of disk, and separates with the rule gusset between every blade; One side of said disc centre is provided with cast gate, and opposite side is provided with a core print.
As preferably, said blade is 20.
As preferably, said per two blades are formed a herringbone blade loam core.
The beneficial effect of the utility model is: the utility model vane thickness is even, and runner is well-balanced unimpeded, does not stop up; Leaf model is made simple, and model frock quantity is few, and need not consider the positioner in blade loam core, the left and right sides; Adopt machine tooling model frock, the complicated irregularly shaped regular shape that can process for lathe that changes that manual operations could realize, the machining accuracy through lathe improves model accuracy, makes process, difficulty and the cost reduction of modelling, maintenance.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the casting sketch map of the utility model.
Among the figure: 1, disk; 2, blade; 3, rule gusset; 4, cast gate; 5, core print.
The specific embodiment
To combine accompanying drawing and specific embodiment that the utility model is done further explain below.
Embodiment: as depicted in figs. 1 and 2; The utility model comprises a disk 1, and said disk 1 circumferentially is evenly distributed with 20 blades 2 along it, and every blade 2 is along the radially setting of disk 1; And separate with rule gusset 3 between the every blade 2; Said per two blades 2 are formed a herringbone blade 2 loam cores, and a side at said disk 1 center is provided with cast gate 4, and opposite side is provided with a core print 5.
The utility model evenly is fixed on 20 blades 2 on the disk 1, rule gusset 3 is set, between blade 2 when being provided with; Per two blades 2 are formed lambdoid unit blade 2 loam cores; Again holistic impeller loam core is made up in these unit blade 2 herringbone loam cores, one side at (being disk 1) center is provided with cast gate 4 in the impeller loam core, and opposite side is provided with core print 5; Thereby pour into a mould, accomplish impeller.
Claims (3)
1. the casting frock of a herringbone impeller; It is characterized in that: it comprises a disk; Said disk circumferentially is evenly distributed with several pieces blades along it, and every blade is along the radially setting of disk, and separates with the rule gusset between every blade; One side of said disc centre is provided with cast gate, and opposite side is provided with a core print.
