| 摘要 |
The invention concerns a molding device for making by blow molding or stretch blow molding thermoplastic containers capable of having different heights, comprising a module ( 1 ) with two mutually mobile half-molds ( 2 A, 2 B) and an axially mobile mold base ( 5 ); the mold base is supported by a support ( 22 ) with which are associated in operation means for axial displacement; the mold base, and its support ( 22 ) are secured by spacing means ( 24 ) with adjustable variable heights relative to the height of the molding cavity and provided in the form of threaded means with reverse-pitch double threading; the mold base can thus be positioned axially relative to the height of the molding cavity without modifying the support ( 22 ) and/or the displacement means which are operatively associated with it.
