[0031] See also Figure 1-Figure 6 , the utility model provides a technical solution: an injection mold for a rotary valve capable of alternate molding, provided with an upper fixing plate 1 assembled by an injection molding machine, and a degumming plate 2 is installed on the lower surface of the upper fixing plate 1;
[0032] It includes: an upper template 3, which is installed on the lower surface of the degummed plate 2, and the lower surface of the upper template 3 is fitted with the lower template 4, and the left side of the inner surface of the upper template 3 is nested with a cavity 5, and the inner surface of the cavity 5 is nested with an insert 6, and the inner surface of the insert 6 is limitedly assembled with an internal component 7;

[0037] The core-pulling component 11 and the positioning member 12 form a limiting engagement structure, and the core-pulling component 11 and the second built-in member 13 form a built-in structure. Moreover, the second built-in member 13 and the hard component 9 form a through structure through the cooperation between the first built-in member 7.
[0038] When it is necessary to demold the hard component 9 and the soft rubber component 17, the upper fixing plate 1 positioned and assembled on the injection molding machine can be used in the Divinycell. And with the adjustment of the lower fixing plate, the glue removal plate 2 and the upper template 3 can be effectively separated, and the upper template 3 and the lower template 4 will also be separated synchronously. And the separation between the first cavity 5 and the first core 8 can be stably controlled.
