<p>The purpose of the present invention is to provide a die-casting die which is less likely to cause a gas defect. A die-casting die is configured in such a manner that a runner (1) is branched at a branch section (3) and that cavities are communicated with the respective downstream ends of the branched runners. The runner (1) comprises a main runner (2) which is located upstream of the branch section (3) and sub-runners (4) which are located down-stream of the branch section (3). A volume section (5) having an opening (6) open toward the main runner (2) is formed at the portion of the branch section (3) which is located on a line extended from the main runner (2). The width of the opening (6) is greater than the width of the main runner (2).</p> |
