Abstract

Die Erfindung bezieht sich auf ein Verfahren zur Herstellung eines Gehäuses (12) für einen Drosselklappenstutzen (10), das eine besonders hohe Formstabilität aufweisen soll. Hierzu wird das Gehäuse (12), das eine Drosselöffnung (16) für eine Drosselklappe (20) aufweist, im Spritzgussverfahren aus Kunststoff (14) hergestellt, wobei ein zumindest im Bereich der Drosselklappe (20) die Drosselöffnung (16) bildender Metallzylinder (28) teilweise von Kunststoff (14) umspritzt wird. Hierbei wird vor dem Spritzgussverfahren gegen die Innenfläche (33) des Metallzylinders (28) ein Spreizkern (50) gespreizt. Während des Spritzgussverfahrens ist die Innenfläche (33) des Metallzylinders (28) zumindest teilweise von dem Spreizkern (50) abgestützt. Nach dem Spritzgussverfahrens erfolgt zur Entfernung des Spreizkerns (50) aus dem Innenraum (70) des Metallzylinders (28) eine Verringerung des Aussenumfangs (80) des Spreizkerns (50).

Figure 00000001
The invention relates to a method for producing a housing (12) for a throttle valve connector (10), which is said to have a particularly high dimensional stability. For this purpose, the housing (12), which has a throttle opening (16) for a throttle valve (20), is produced by injection molding from plastic (14), a metal cylinder (28) forming the throttle opening (16) at least in the region of the throttle valve (20) ) is partially encapsulated by plastic (14). Before the injection molding process, an expanding core (50) is spread against the inner surface (33) of the metal cylinder (28). During the injection molding process, the inner surface (33) of the metal cylinder (28) is at least partially supported by the expanding core (50). After the injection molding process, in order to remove the expansion core (50) from the interior (70) of the metal cylinder (28), the outer circumference (80) of the expansion core (50) is reduced.
