摘要： A partition plate for an intake port of a cylinder head to be manufactured by cast molding is preliminarily set prior to the cast molding in a sand core applied to form the intake port and then cast in by the cast molding to partition the intake port into a plurality of ports. The partition plate is provided with an intake-side distal end, a cylinder-side distal end, a pair of side edges continuous with the intake-side distal end and the cylinder-sided distal end and to be cast in by molten metal during the cast molding. Each of the pair of side edges having end faces facing in a thickness direction and a side end face continuous with the end faces. The partition plate is further provided with a promoter section provided on at least one of the side end face and the end faces of each of the pair of side edges to promote solidification of the molten metal.
摘要翻译：用于铸造成型的汽缸盖的进气口的隔板在铸造之前预先设置在用于形成进气口的砂芯中，然后通过铸造成型铸造以将进气口分成多个端口。分隔板设置有进气侧前端，气缸侧前端，与进气侧前端和气缸侧前端连续的一对侧边缘，并且在该铸造成型。所述一对侧边缘中的每一对具有面向厚度方向的端面和与端面连续的侧端面。分隔板还设有在一对侧边缘中的每一个的侧端面和端面中的至少一个上设置的促进部分，以促进熔融金属的固化。
