Injection compression mold comprises a female die (14) with a mold cavity (17), a male die (13), an annular sealing unit around the male die, and studs (15) for rigidly connecting the sealing unit to the female die, at least between the injection phase and the compression phase. The periphery of the male die coincides with the periphery of the mold cavity and the sealing unit creates a sealing zone that is crossed by the closure plane between the dies. |
