    摘要: An EGR cooler (23) that cools EGR gas flowing through an EGR gas passage of an engine by heat exchange between the EGR gas and coolant flowing through a coolant outlet passage (32). The EGR cooler (23) includes: a housing (31) that is attached to one end of the engine and forms the coolant outlet passage (32); an exhaust gas recirculation pipe (33) that forms therein a part of an EGR gas passage of the engine in an inner periphery thereof and is supported by the housing (31) in which EGR gas flowing through the exhaust gas recirculation pipe (33) exchanges heat with coolant flowing through the coolant outlet passage (32); and an expansion joint (35) that is fixes the exhaust gas recirculation pipe (33) to the housing (31) and is elastically deformed to compensate for expansion/contraction of the exhaust gas recirculation pipe (33) with respect to the housing (31).

    摘要: The gist of the construction, casting conditions and program for a casting method capable of attaining the above object of the present invention resides in a method comprising the steps of closing gates (4) with a counter tip (7) after lower and upper molds (1, 2) heated to a predetermined temperature have been clamped, pouring melt into a sleeve (5) in which a plunger tip is lifted a predetermined distance, lowering the plunger tip (9) while displacing the counter tip to a predetermined position to open the gates, which are formed such that the ratio of the volume of products to the cross-sectional area of the gates is 20-40 (the volume of products/cross-sectional area of gates = 20-40), to allow the melt to flow into cavities (3) via the gates by the force of gravity alone with the plunger tip reaching the upper surface of the melt (15) the moment a percentage of the melt placed in the cavities has reached a value between 20 and 70%, and pressure-filling the cavities with the melt by the plunger tip with the melt passing through the gates at 0.4-0.8 m/sec.

    摘要: A method of casting a pipe having an axially elongate hole of which a front end (14b) is closed, comprises the steps of positioning a rod-like center pin (14) for forming the blind hole in a predetermined positional relation to cavity defining surfaces of a die cavity, supporting the positioned center pin sidewise with a support pin (17) to prevent positional deviation of the center pin, charging molten metal into the die cavity, retracting the support pin apart from the center pin, and replenishing a space formed by the retraction of the support pin with molten metal.

    摘要: A casting mold includes a cavity formed therein, and a core projecting into the cavity. The core forms a concave portion in a cast product, and it exhibits a thermal expansion coefficient being equivalent to or more than a thermal expansion coefficient exhibited by a molten metal to be charged into the cavity. Hence, the core greatly expands thermally during casting, and it keeps the expanded state during the solidification of the molten metal. Accordingly, the casting mold can prevent the casting defects resulting from the shrinkage cavities from arising in the resulting cast products. All in all, the casting mold can obviate to give the core a tapered configuration, and it can reduce the after-casting machining allowance to be provided in the resulting concave portion.
