Nowadays, in the sand mold manufacturing industry, the aluminum alloy formwork for casting is usually processed and manufactured by CNC
Sand casting process equipment is the general name of molds and devices used in the process of molding, core making
The numerical simulation of temperature field is the basis and core module of ProCAST software simulation. Through the simulation of
During sand casting, under the action of gravity, the liquid metal first enters the mold cavity through the sprue, enters
When CAD and CAE technology are used to assist the design of gating and riser system of sand casting coupling
Figures (a) and (b) reflect the flow of liquid metal in the sand casting axle housing when the liquid metal
In sand casting, the gating system is a reserved channel in the sand mold, which is used to guide the
Figure (a) is a real-time screenshot when the molten metal just fills the sprue at the beginning of pouring and
The sand casting structure of coupling parts is often simpler than that of finished parts, because many structures of finished
Sand casting process parameters mainly include dimensional tolerance, linear shrinkage, draft angle and other aspects. The determination of these process
By designing the test device by pouring method, the thermophysical parameters of glass quartz sand used in actual sand mold
At the place where the upper and lower cores form a diaphragm, chromite ore sand is used to replace ordinary
The diaphragm is connected with the main body of sand casting, stiffener, middle annular structure, oil passage and boss, resulting
The sand casting material of gearbox shell is ZL114A aluminum alloy, with high requirements for mechanical properties: tensile strength ≥
The shrinkage porosity produced in the solidification process of sand castings is mainly predicted by using the shrinkage porosity criterion.
Taking the tractor split sand casting axle housing as the research object, the axle housing is made of zg40mn low
Generally speaking, the higher the pouring temperature of sand casting, the better the fluidity of alloy liquid and the more
Because the deformation of blade sand casting is difficult to predict and control, and the deformation of blade sand casting
The setting of simulation parameters is the same as that of mold filling process. After setting, the calculation and Simulation
From the simulation results of traditional gating system, the following two aspects should be paid attention to when designing the
After the pretreatment, the mold filling simulation experiment of blade sand casting will be carried out. The simulation results are
1.Establishment of finite element model The sand casting process of hydraulic turbine blade is simulated and analyzed by ProCAST software.
We call all the channels of molten metal entering the mold cavity in the mold as the gating system, which
For the same sand casting, different pouring speed corresponds to different pouring time. In the process of molten metal entering
The pouring position of sand casting usually refers to the position of the axle housing in the mold during pouring.
Steel contains no other alloy elements except carbon and a certain amount of silicon and manganese alloy elements for deoxidation.
The riser can store a certain amount of liquid metal and can feed sand castings. The purpose of feeding is
Turbine blade is one of the three major parts of turbine runner (upper crown, lower ring and blade) which is
Turbine blade is one of the three major parts of turbine runner (upper crown, lower ring and blade) which is
