Definitions

  • the invention concerns a procedure for the production of an in at least two- subsequent mouldings moulded object in a mould consisting of at least three mould parts and a machine for the performance of this procedure.
  • Such a two component moulding can preferably be realized in a so-called index mould.
  • This is a mould where one of the two mould parts, either the stationary front part with the injection unit or the movable back part with the ejection unit, is equipped with a build-in turning table.
  • the turning table can preferably turn 180 degrees around an axis passing through the centre of the turning table and parallel to the mutual direction of movement of the two mould parts.
  • the first part of the for the co- moulding intended object e. g. can be moulded in those of the closed mould formed mould cavities which are placed in the upper half of the mould.
  • the last part of the object subsequently can be moulded in the mould cavities, which qua the first moulding is formed in the lower half of the mould.
  • moulds that beyond the two common mould parts, the stationary front part and the movable back part, comprises a third mould part. This is the case in the so-called three plate tools.
  • the inlet channels in the mould e.g. are placed between the two foremost mould parts and the objects between the two hindmost mould parts.
  • the objects and the inlets are torn off and ejected separately when the mould is opened after each moulding cycle.
  • the advantage of such a mould is that the inlets and the finished objects hereby can be kept separated more easily and you can save the expensive hot-runner systems.
  • sandwich moulds/stack moulds There are also known another kind of moulds consisting of more than two mould parts, the so-called sandwich moulds/stack moulds.
  • a sandwich mould consists of three mould parts as there beside the front part and the back part is a middle part.
  • This frame system connects e. g. via a knee hinged joint system the middle part, whereto the frame system is firmly attached, with the two outermost mould parts.
  • the advantage of such a sandwich mould is that there in principle are moulded twice as many objects per time unit compared to a common mould consisting of two mould parts.
  • the procedure according to the invention is characterized by the fact, that in each of the at least two in the closed mould formed pair of cavities is, when the mould is open, at least one of the two mould parts or parts hereof turnable in relation to the opposite mould part, e. g. 180 degrees around an axis which is parallel to the mutual direction of movement of the mould parts.
  • the principle in the procedure according to the invention can in its simplest form be described in the case with three mould parts, where the middle part alone contains a turnable element.
  • a single object comprising two parts, e. g. a screw cap of plastic and the matching threaded tube neck, intended for the placement on a pill jar.
  • the screw cap preferably is moulded at first, e. g. in the upper half of the mould. After cooling and opening of the mould the middle part is turned half a round, hereafter the mould is reclosed. With the inside of the screw cap serving as a part of the mould the corresponding threaded tube neck is moulded. Simultaneous with the final moulding of the first set of the assembled objects in the now downwards placed part of the mould, is in the upper half of the mould moulded the next set of screw caps, and so the process is continued.
  • the cycle described above is for two similar objects moulded assembled and ejected together per cycle. In principle the case is the same for a larger number of mould cavities in the mould, as well as if the mould consists of more than three cooperating mould parts .
  • the procedure . according to the invention can hereby achieve a considerable saving in both time and costs by the moulding of objects consisting of two or more components compared to the hitherto known methods for subsequent moulding.
  • the design of the mould tool you will have to consider that the first moulded parts of the objects after cooling and opening of the mould remains in/on the turnable mould part(s). Hereby at the turning they will e.g. be moved from the upper half of the mould to the lower half. The simplest way to obtain this is by a better hold-down in the turnable mould part(s) than in the not turnable.
  • fig. 1 shows a design according to the invention in a closed position
  • fig. 2 the same in an open position
  • fig. 3 the same in an open position with the middle part turned
  • fig. 4 the same in a closed position
  • fig. 5 the same in an open position by the ejection of the finished objects
  • fig. 6 the same after a new turning in an open position
  • fig. 7 another design in an open position
  • fig. 8 a third design in an open position.
  • FIG. 1 is shown in closed condition from the side a cross section of an example of a mould for the performance of the procedure according to the invention.
  • the mould consists of a stationary front part 1, a movable back part 2, as well as a herby simultaneous movable middle part 3, that also is intended to be turned around a here horizontal axis 4.
  • a screw cap in the two above the axis 4 formed mould cavities 6.
  • the front part 1 and the back part 2 is shown the large cores 7 at the top for the first moulding and the somewhat smaller cores 8 for the following moulding.
  • the middle part 3 is shown the symmetrical placed and identical cavities 9 that together with the large cores 7 form the mould cavities 6.
  • FIG. 2 shows a cross section of the same mould in an open position, where the two first parts of the assembled objects 5 are moulded and positioned in the cavities 9 in the middle part 3.
  • fig. 3 is shown the same mould still fully opened, but where the middle part 3 is turned 180 degrees around the horizontal axis 4, so that the two first moulded parts 5 now are positioned precisely facing the smallest cores 8 in the two not turnable mould parts 1 and 2.
  • Fig. 5 shows the same mould in an open position during the ejection of the two final moulded objects.
  • Fig. 7 shows in perspective another design of a mould with three parts.
  • the middle part 3 is parted in a turnable part 3' and a not-turnable part 3'', where the turnable part 3' is positioned by means of a not on the drawing shown ball bearing or the like, which eases the turning because the pate/plates are not stressed on their respective closing area during the turning.
  • the turning axis 4, which here is a real turning axle 4', is designed in such a way that it can pass through the two not-turnable mould parts 1 and 2 while it activates the turnable part 3' of the middle part 3.
  • fig. 8 in perspective a third design is shown of a mould according to the invention with five mould parts resulting in four separate moulds, here shown in an open position. In the example shown there are 30 plus 30 cavities in each of these moulds, so that per completed cycle a total of 120 assembled objects are ejected.
  • a special ejecting system could have been shown, preferably for the placement in the turnable middle part, consisting of three plates. Of these the two outermost can be movable in relation to the middle, whereby they can serve as a stripper plate and/or make space for an inlet system.

Abstract

L'invention concerne un procédé de moulage d'un objet assemblé et la machine correspondante. L'objet fabriqué en au moins deux moulages successifs est moulé dans un moule comprenant au moins trois parties. Dans chacune des cavités (6) du moule fermé se trouve, lorsque le moule est ouvert, l'une au moins des parties (3) du moule ou une partie de celui-ci (3') susceptible d'effectuer une rotation de 180 ° autour d'un axe (4) ou d'un essieu (4'), parallèle à la direction mutuelle du mouvement de la partie du moule par rapport à la partie opposée du moule. Dans un moule comprenant trois parties, la partie médiane (3) peut par exemple pivoter par rapport aux deux parties (1) et (2) du moule les plus à l'extérieur.
