Thermal behavior on core-pin of aluminum die-casting related to cooling conditions such as casting volume, corepin diameter, cooling water pressure are investigated. It is proved that the maximum core-pin surface temperature and heat flux are approximately 820 K and 3.5 MW/m2, which varies depending on the casting conditions. Using thin wall core pin with high pressure cooling water, the maximum surface temperature would not excess solidus temperature which might cause soldering, and heat flux goes up to 7 MW/m2 more than twice compared to the normal core-pin with thick wall. And it is proved that thin wall core-pin is necessary to control the heat flow from the casting to the core pin. In case of thick wall core-pin, rate limiting factor of heat flow will be heat conductivity which is uncontrollable physical property. © 2016 The Japan Institute of Light Metals.

An object of the present invention is to surely provide a projection of burr by forming an appropriate gap needed to set a cast-in member to a cast-in mold, and by completely closing the gap when the cast-in mold is clamped, and to correct a cast-in positioning (axis mating) to a die-cast component by a clamping operation of the die-cast mold, regardless of a dimensional precision of the cast-in member upon a manufacture. A steel plate cast-in member 2, which is wrapped cast except for a bonding portion 2b to a steel plate bonding member 3 upon molding a die-cast component 1, has a mold contact portion A at a boundary between a cast-in portion 2a wrapped cast with a die-cast component 1 and the bonding portion 2b. When a cast-in mold A is clamped, the mold contact portion 4 is brought into intimate butting contact with the cast-in mold A, whereby a gap S between the cast-in member 2 and the cast-in mold A, i.e., a cavity is closed. Thus, a projection of burr is prevented.

The purpose of the present invention is to reliably prevent burr protrusions by appropriately taking the necessary gap in order to set a cast-in member in a cast-in mold and completely closing the gap when the cast-in mold is clamped, and to correct, regardless of manufacturing dimensional accuracy of the cast-in member, positioning (centering) of the cast-in relative to the die-cast component through the action of clamping the die-cast mold. During formation of the die-cast component (1), a steel plate cast-in member (2), which is cast in while leaving the side of the joined section (2b) joined with a steel plate joining member (3), is provided with a mold contact portion (4) in the border section between the side of the cast-in section (2a) cast into the die-cast component (1) and the side of the joined section (2b), and, by pressing into close contact when the cast-in mold (A) is clamped, the cavity (a), i.e., the gap (S) between the cast-in member (2) and the cast-in mold (A), is sealed and burr protrusions are prevented.
