<p>The present invention describes a blow mold shell (M) of tubular shape, divided in both the longitudinal and transversal direction into individual parts (Ml, M2, M3, M4, M5, M6) or divided in the longitudinal direction into individual parts (MF1 and MF2), each one of said parts featuring a cylindrical shell shape; parts (Ml), (M3) and (M5) are supplementary, as well as parts (M2), (M4) and (M6); the supplementary parts are attached to each other by means of screws (P1); on the longitudinal ends of the supplementary parts there are calibrated grooves (El and E2) of rectangular profile which purpose is to ensure the alignment in the longitudinal axis; on parts (MF1) and (MF2) there are calibrated grooves onto which are assembled the form inserts (IF1, IF2 and IF3) also calibrated; between the supplementary parts of mold (M) there is a locking device made up of pegs (C, CF and CR), which are hidden inside cavities featured on mold parts (M) and attached to it by means of screws (P2 and P3); said locking device is responsible for preventing rotation between said parts as well as allowing its removal or replacement.</p> |
