subject: Blow Moulding Machine Having A New Blowing Mould [print this page] Blow moulding machine having a new blowing mould
It is thus the object of the present invention to provide the vessel blow moulding machinery with a blow moulding machine having a new blowing mould by means of which the blow moulding machine may be changed over from a first vessel type to another second vessel type in a shorter time than hitherto.
In accordance with theblow mold machine, this object is achieved in that a single blowing mould is used as the basic mould for the first vessel type and remains installed on changing over, and only at least one corresponding ring insert for adapting the vessel shape to the other second vessel type is inserted into the blowing mould and is secured by means of appropriate securing means.
The blow moulding machines according to the invention for achieving this object is characterized by a blowing mould which is constructed as the basic mould for manufacturing the first vessel type and which may be changed over by means of at least one corresponding ring insert which may be inserted into the blowing mould and secured within the blowing mould to give the vessel shape of the other second vessel type.
Advantageously, the ring part set for changing over for example from a plugged vessel to a removable-cover vessel body--or vice versa--may be exchanged without the blowing mould or the mould slide having to be removed from the plastic blow molding machine . This is advantageously achieved in that the securing means, preferably threaded screws, for securing the ring part set to the blowing mould or to the mould slide are accessible from the outside or from below and are manipulable. On changing over, the blowing mandrels are not changed and the blowing mould equipment is not altered to another type.
To blow molding machine manufacturer a plugged vessel having a peripheral carrying and transport ring in the peripheral region of the vessel upper surface, in which at least one, preferably two plug hole openings are made, the blowing mould is equipped, at the mould side and/or at the corresponding associated fixed blowing mould part for upsetting the carrying and transport ring, with an exchangeable ring part set having the contour of the carrying and transport ring.
