用于制作多部件中空制品的方法和设备以及由此制作的制品
摘要：
本发明公开了一种用于制作多部件中空制品的注塑方法和设备，以及由此制作的制品。所述方法包括由第一塑性材料注塑中空主体，所述中空主体具有带有穿过其的至少一个通气孔的壁和注塑在邻近于所述通气孔的区域中的至少一个翻盖。所述翻盖注塑在其中所述通气孔打开的第一位置中。所述翻盖能够以铰接方式从所述第一位置移动到其中所述通气孔由所述翻盖闭合的第二位置。在所述翻盖被折叠到所述第二位置中之后，所述中空主体，包括所述折叠翻盖，至少部分与第二塑性材料包覆模制，其中所述第二材料基本上被排除通过所述通风孔渗漏到所述中空主体中。所述设备包括用于注塑中空主体的第一模具杆、用于与第二塑性材料包覆模制所述中空主体的第二模具杆、和用于移动所述翻盖并且可选地将所述翻盖保持在所述第二位置中的闭合工具。所得制品在其中空主体中不具有第二材料。
摘要（英）：

The present invention discloses an injection-molding process and an apparatus for making a multi-component hollow article, and the article made thereby. The process comprises molding, from a first plastic material, a hollow body having a wall with at least one vent therethrough and at least one flap molded in an area adjacent to the vent. The flap is molded in a first position in which the vent is open. The flap is hingedly movable from the first position to a second position in which the vent is closed by the flap. After the flap is folded into the second position, the hollow body, including the folded flap, is at least partially overmolded with a second plastic material, wherein the second material is essentially precluded from leaking into the hollow body through the vent. The apparatus comprises a first mold bar for molding a hollow body, a second mold bar for overmolding the hollow body with a second plastic material, and a closing tool for moving, and optionally retaining, the flap in the second position. The resulting article has no second material inside its hollow body.
