Embodiment Construction

[0021] The embodiment of the invention is based on the known setup of a molding injection machine, which is arranged on a frame 1 . Here, a fixed profile fastening plate 2 is provided which forms an openable and closable clamping unit (Schliesseinheit) together with a mobile profile fastening plate 5 which is supported against a support plate 4 and is supported by The driving device 7 drives. Here the mobile profile fastening plate 5 moves along a draw bar 6 which absorbs the traction forces between the fixed support plate 2 and the support plate 4 . A mold half 9 is provided on the stationary profile fastening plate 2 and a further mold half 8 is provided on the mobile profile fastening plate 5 . This half-mold 8 has a plurality of cores 8', which together with the cavities of the half-mold 9 form a corresponding number of cavities during the joint movement of the clamping unit.

Abstract

The invention relates to an injection molding machine for manufacturing a plurality of injection molding elements in a period, the injection molding machine comprises: moulds (8, 9) provided with a plurality of cavities (52); a taking-out device (11) and / or transmitting device (12), wherein, the taking-out device (11) and / or transmitting device (12) comprise / comprises receiving openings (76, 86) with the number corresponding to the number of the cavities (52) of the moulds; and re-cooling devices (19, 60) with the number over integer times of the number of the cavities of the moulds, in order to guarantee suggestion of sufficient cooling and use of constant re-cooling devices, the spacing between the receiving openings (76, 86) in the taking-out device (11) or transmitting device (12) is changeable.

Description

【Technical field】 [0001] The invention relates to an injection molding machine according to the preamble of claim 1 . 【Background technique】 [0002] Injection molding machines for producing a plurality of injection molded components in a single cycle have been disclosed. As an example, the production of preforms for plastic bottles (so-called preforms) should currently be used. Here up to 200 preforms are produced simultaneously in a cycle in multiple cavities. The mold has a corresponding number of cavities. For example, 48-fold, 72-fold, 96-fold, 144-fold and 192-fold molds are known, which have a corresponding number of cavities (also called form nests). [0003] To ensure a particularly efficient production method, the preforms are quickly removed from the mold while still hot. However, in order to ensure sufficient cooling, thereby avoiding as far as possible crystallization effects and preventing reheating and subsequent co-bonding, recooling devices are provided ...
