Abstract
1,229,361. Injection-blow moulding; transfer mechanism. BLEWIS & SHAW (PLASTICS) Ltd. 25 Aug., 1969, No. 42239/69. Heading B5A. In an injection-blow moulding machine, the transfer mechanism comprises a transporting member TM to which the parison stick 5 may be connected, carriage means 14, 15 and a support structure SS alsong which the carriage means may be traversed from the injection mould to a blow mould. In the embodiment illustrated, the parison stick 5 is connected to the transporting member TM by clips 10 and pegs 22, the carriage means comprising block 15 housing shafts 14 on which are mounted rollers RB. The carriage means are moved along between plate TP, and plate 26 of the support structure by rack-driven fingers F engaging spigots 42, 43 on the transporting member TM and parison stick holder, respectively. During this movement, lug 55 on the parison stick holder slides into recess 54 on hydraulically actuated head 53 which retracts to disengage the parison stick holders from the transporting member TM to place the parison sticks in the respective mould. The apparatus also comprises an injection mould IM located between a pair of blow-moulds BM1, BM2, each mould comprising a fixed part 1 and a movable part 3. The ejector means comprises a set of fingers which when raised pass between the parison sticks, above the level of the article, when these are removed from the blow-moulds and which then descend to remove the article. Air is supplied at each blow-mould through air lines AL having terminal connectors 59 engaging with inlet nozzles 60 on the parison stick holders. Each movement of the apparatus may be effected automatically at the termination of the preceding movement by a series of limit switches controlling the valves of the hydraulic circuitry &c. From the position when all the moulds are closed, the left blow mould, BM1, is opened, the left ejector raised, the articles on the parison sticks are pushed from this mould by extension of head 53 and the ejector lowered to strip the articles. The injection mould is opened and the parison sticks pushed therefrom to engage the transporting members. The racks are then actuated to interchange these parison sticks and the injection- and left blow-moulded BM1 closed. The right blow mould, BM2, then opens and the articles are ejected as above, and, after opening the injection mould, these parison sticks are interchanged and the moulds closed thereon. The supporting structure has a passing loop (Fig. 4, not shown) for the carriage means and the carriage means is halted in position by retractable stops (CS1, CS2, Figs. 2, 3, not shown) either side of the injection mould and fixed stops (RHS, LHS) at the outer extremities of the blow moulds.
