Abstract

Official abstract text for this publication.

A method of casting a casting product having tubular flow passages includes: attaching a cast-in pipe insert, having outer and inner fixing members to which both ends of pipes are coupled, respectively, to a fixed mold; assembling a movable mold with the fixed mold; injecting a molten metal into a cavity defined inside the fixed and movable molds; ejecting a casting product from the assembled molds after injecting the molten metal; and removing the outer and inner fixing members from the casting product.

First claim

Opening claim text (preview).

What is claimed is: 1. A method of casting a casting product having tubular flow passages, comprising: attaching a cast-in pipe insert, having outer and inner fixing members to which both ends of pipes are coupled, respectively, to a fixed mold; assembling a movable mold with the fixed mold; injecting a molten metal into a cavity defined inside the fixed and movable molds; ejecting a casting product after injecting the molten metal; and removing the outer and inner fixing members from the casting product, wherein the fixed mold or the movable mold has a cone portion at a front end thereof, wherein the cone portion is inserted through and coupled with an inner side of the inner fixing member, wherein each of the outer fixing member and the inner fixing member has a ring shape having a circular cross section, wherein a diameter of the inner fixing member is smaller than a diameter of the outer fixing member, wherein the inner fixing member is disposed inside the outer fixing member. 2. The method according to claim 1 , wherein the cast-in pipe insert includes two or more pipes. 3. The method according to claim 1 , wherein the injecting a molten metal is carried out by a high-pressure casting. 4. The method according to claim 1 , wherein the pipes are arranged in the cavity.
