Energy storage box shell mold installation method

What is the role of a core box mold & temperature control?

In the precision low-pressure casting industry, in regard to this almost closed internal surface shape of the water-cooled shell of the new energy vehicle motor, the structure design of the core box mold and temperature control play a decisive role in the internal molding of the casting.

How do you mold a hot core box?

Mold structure of water-cooled shell of the hot core box. The core methods of the hot core box are as follows: the moving pallet core method, the ejector rod core pulling method and the rotary core pulling method.

How to heat a mold?

The mold’s working temperature of the core box is up to 250 °C or higher, needing a long time to heat repeatedly, so we chose the imported seamless stainless steel tube which can resist the high temperature as the heating tube shell, with a magnesium oxide pipe inside the high temperature, and choose the antioxidant nickel chromium as heating wire.

What is the normal working temperature of a sand box mold?

The normal working temperature of the core box mold is 210 °C. When the temperature is reduced by 10 °C, the curing degree of the sand core will be greatly reduced. Consequently, the density and mechanical properties of the sand core will drop off.

How to design a mold using Pro/e software?

The PRO/E software is used to design the mold by five opening directions, thus forming a structural design as shown in Figure 2, which is mainly composed of the core box body 1#, 2#, 3#, 4#, sand shooting plate 5#, extraction core box body 6#, supporting core plate 7# and other components. 3 Mold structure of water-cooled shell of the hot core box.

What is the optimization scheme of gating system for injection mold combination cavity?

Aiming the problem of flowing unbalance for the injection mold combination cavity, the optimization scheme of gating system was determined. The shunt channel sizes were improved based on the flow balance analysis and the gate sizes were improved based on DOE test.
