Apparatus for producing at least one container, in particular in ampule form, made of thermoplastic material

摘要

An apparatus for producing at least one container, in particular in ampoule form, made of thermoplastic material, includes a mold (13) with mold components (15, 17). A first calibrating mandrel (19) and a second calibrating mandrel (23) are movable coaxially in relation to the longitudinal direction (21) of the container (1) and in relation to one another. The first calibrating mandrel (19) through the container (1) located in the mold (13) and the second calibrating mandrel (23) from the outer side of the container (1), move into a shaping position in which they calibrate a bottom area that forms at least part of a container bottom between the mandrel ends. A severing device has a movable cutting or punching surface (37) to sever excess plastic material forming during the shaping process in interaction with a cutting or bearing edge on the mold components (17) assigned to the bottom region. The severing device has a cutting device (35) that is guided in an axially displaceable manner on the second calibrating mandrel (23), forms the cutting or punching surface (37) and can move between the withdrawn position and the punching position independently of the movement of the respective calibrating mandrel (23).

主权项

1. An apparatus for producing a container of thermoplastic material, comprising:
a mold with mold components movable relative to one another between an open position and a closed position and in which synthetic plastic material can be placed against walls of said mold components by a pressure gradient to act on the plastic material and to form a container; first and second calibrating mandrels movable coaxially relative to a longitudinal axis of the container and to one another, said first calibrating mandrel being movable through the container located and formed in said mold components, said second calibrating mandrel being movable from outside the container located and formed in said mold components into a shaping position to calibrate a bottom area forming at least part of a container bottom of that container between adjacent mandrel ends of said first and second calibrating mandrels; and a severing device having a movable cutting surface severing excess plastic material, said cutting surface interacting with a cutting edge on a bottom portion of said mold components, said severing device having a cutting device guided on and axially displaceable on said second calibrating mandrel and forming said cutting surface, said cutting device being movable between a retracted position and a punching position independently of movement of said second calibrating mandrel, said caning surface being inclined at an acute angle relative to said longitudinal axis.
