Description

A kind of blade casting mould
Technical field
This utility model belongs to casting field, relates to a kind of for the blade casting mould with leaf product, specifically relates to And one blade casting mould.
Background technology
In the manufacture process with leaf product, especially in the manufacture process of enclosed impeller.Its blade position, past Toward in three-dimensional twisted shape, using the mode of direct mechanical processing to manufacture, difficulty is very big, even cannot process.
Existing blade manufacture method, is arranged to blade shape by mould and is molded.But at casting complex shape During the most three-dimensional twisted blade of the blade of shape, mould is provided directly as blade shape highly difficult.Because this is by blade The difficulty of casting is transformed into the difficulty of mould processing.Casting relative to blade, the course of processing of mould is more complicated to be difficult to control to. The mould of blade is all to need to arrange the hole matched with blade shape in mould structure, when blade shape complexity, The hole of the internal manufacturing complex shapes of blade mold is extremely difficult, the most indirectly adds the difficulty of blade casting processing;
The structure that existing blade mold or employing upper and lower mould match, although the structure that upper and lower mould coordinates can be by leaf The shape of sheet is divided into two parts, makes the groove of adhered shape respectively, but the most three-dimensional twisted blade is perpendicular on upper and lower mould Shape in plane and transverse plane is the most more complicated, so when upper and lower mould makes the groove of laminating blade shape the most very Difficulty, and the structure of blade the most all can possess upper limb and lower edge, and this is accomplished by inside upper and lower mould processing the sky matched Gap, it is unworkable for will processing space inside a modular construction, it is impossible to realize processing to mould itself, and then also without Method realizes the casting to blade and processes.
During owing to making low-melting alloy blade, need to be cast in mould the aluminium alloy of fusing, need in the process It is noted that the parameters such as aluminium alloy temperature, mould temperature, cooling.As too low in aluminium alloy cast temperature, mold temperature is too low may water not Foot, cold shut;Cast temperature is too high, mold temperature is too high, rate of cooling is the least it is possible that surface microstructure is thick, any surface finish It is poor to spend.
Utility model content
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, it is provided that a kind of blade casting mould, passes through Mould is carried out piecemeal setting, cooperates between each piecemeal, it is possible to well make three-dimensional twisted blade or leaf model.
