Rotary injection mold for elastic housing of neckband headset and manufacturing method

A rotary injection mold for an elastic housing of a neckband headset, comprising an upper mold core and a lower mold core,

• wherein the lower mold core is provided with a main installation cavity and a control end installation cavity, the main installation cavity is installed with a rotary mold core, the rotary mold core is provided with two half-ring molding channels which are symmetrical with a rotation axis thereof, and the two half-ring molding channels are rotatable and positioned between a first injection position and a second injection position;
• the upper mold core is provided with a first upper mold core and a second upper mold core;
• wherein when the upper mold core and the lower mold core are closed, a primary injection cavity is formed between the first upper mold core and the half-ring molding channel at the first injection position, by which a supporting member supporting a neck of the neckband headset is molded;
• a secondary injection cavity is formed between the second upper mold core and the half-ring molding channel at the second injection position, by which a strip member wrapping the neck of the neckband headset is molded;
• the control end installation cavity is configured to install two control end injection molds, and each of the control end injection cavities is respectively provided with a control end injection cavity by which a control end elastic casing for wrapping an insulation shell of a headset controller is molded;
• two control end injection cavities are hermetically communicated with the secondary injection cavity through a neck channel, so that the control end elastic casing and the strip member are molded together to integrally form an elastic housing that completely wraps the neckband headset.
