sand casting

The single side bottom pouring with internal gate is adopted. The flow and temperature distribution of ZL105 metal liquid filling

Fig. 1 shows the temperature field changes of sand castings at 10s, 60s, 130s and 340s after the molten metal

Observing the change of temperature field in the solidification process of sand castings can accurately predict the location of shrinkage

The first Pouring Scheme of cylinder head – the temperature field distribution of sand casting with single side top injection

All the mandatory clauses in the current nine mandatory national standards for foundry machinery have been integrated, streamlined and revised

Since the sand casting material is aluminum alloy ZL105, an open gating system is adopted. It has the following characteristics:

(1) Gating system optimization. Aiming at the problem of unstable liquid metal filling, the gating system was improved. The optimized

(1) Mold filling simulation analysis. Figure 1 and Figure 2 are the simulation diagrams of sand casting at 7.5 s

The working environment of engine cylinder head in the engine is poor, which needs to bear high thermal load and

For the second Pouring Scheme of cylinder head, the temperature field distribution of symmetrical top injection inner gate during mold

Firstly, the sand core design and block processing of the model are carried out. At the same time, the block

The temperature cooling curve of sand castings in phenolic urethane resin sand is shown in the figure. From figure (a),
