Definitions

  • the invention relates to a mould arrangement for injection moulding, which is meant particularly for manufacturing of pipe fittings or like that are made of plastic and the dimensions and/or forms of which differ from each other, whereby at least partly interchangeable mould and/or core surfaces are being used.
  • mould arrangement comprises a sector cradle that can be placed in a mould frame in two or more positions particularly in order to enable manufacturing of pipe fittings with differing joint angles by means of one and the same mould frame.
  • a mould frame belonging to the mould ' arrangement according to the invention is adequately big-sized, whereby all mould cavities that are needed for the pipe fittings, differing from each other by diameters and joint angles thereof, fit therein in order to form the external shape of each ⁇ pipe fitting to be manufactured.
  • the amount of mould material that needs machining is low, which significantly decreases production costs.
  • the mould raw material consumption e.g. for a product family with seven products is approximately 6040 kilos, when instead the corresponding consumption is typically approximately 27300 kilos, when applying standard moulds. Thanks to the invention the manufacturing costs will thus remain remarkably lower per each product to be manufactured when compared to the use of standard moulds.
  • Modification of the mould arrangement according to the invention for differing products is particularly fast when e.g. guiding assemblies operated by hydraulic organs are being used for moving of each mould sleeve and core, being coupled to the sector cradle, into contact with the fixed and turnable joining ends of the mould frame.
  • the mould cavity forming the external shape of the pipe fitting to be manufactured at any given time can be replaced simultaneously, when the mould frame has been opened and the sector cradle is being adjusted in respect with the mould frame to a joint angle desired at any given time.

  • the invention relates to a mould arrangement for injection moulding, which is meant particularly for manufacturing of pipe fittings or like that are made of plastic and the dimensions and/or forms of which differ from each other, whereby at least partly interchangeable mould and/or core surfaces are being used.
  • the mould arrangement comprises a sector cradle
  • a core 4 to be used therewith comprises e.g. with reference to a cross section shown in figure 2 a first auxiliary frame 4a to be coupled with the sector cradle 3 and tip parts 4b to be coupled removably with the first auxiliary frame for each differing pipe size and/or joint angle of the pipe fitting to be manufactured.
  • the mould arrangement comprises interchangeable fitting mould parts 5 for each joint fitting, such as a plug end and/or a socket end, of a different size for the pipe fitting to be manufactured.
  • a fitting mould part 5b for forming of the socket end and correspondingly on the left hand sided cross section a fitting mould part 5a forming the plug end.
  • the mould arrangement comprises particularly with reference to the cross section shown in figure 3 a second auxiliary frame 6 for coupling of a fitting mould part 5 into its place in connection with a fixed joining end II of the mould arrangement.
  • the mould arrangement comprises interchangeable mould cavities 2, to be coupled with a mould space T of the mould frame 1 that has one or more parts, for each differing pipe size and/or joint angle of the center part for the pipe fitting to be manufactured.
  • a center of the sector cradle 3 is arranged on a same axis as a mould cavity 2, being coupled to a mould space T, and turnable in respect with the mould frame 1 preferably at an angle between 0 - 135° (though from figure 1 can be seen only an adjustment region: 0 - 90°) .
  • the position of the sector cradle 3 is arranged steplessly adjusted, which makes possible totally free choosing of the joint angle of the pipe fitting to be manufactured.
  • the position of the sector cradle 3 may be arranged on the other hand also to be adjusted e.g. with angular steps a of

  • a guiding assembly 7 such as sliding rails, slides and/or like, in order to enable moving of each fitting mould part 5 and/or core 4, being coupled to the sector cradle, in connection with the fixed and/or turnable joining end II, I of the mould frame 1.
  • the core 4 being coupled to the sector cradle 3
  • the fitting mould part/parts 5,- 5a/5b of the turnable joining end I and/or of the fixed joining end II are arranged moveable by means of auxiliary powered, advantageously hydraulic organs.
  • the mould cavities 2 thereof to be placed in a mould space T defined partly by the sector cradle 3 and partly by the mould frame 1, and the fitting mould parts 5; 5a, 5b, to be assembled at the joining ends I, II thereof, are one-piece sleeve structures.
  • the invention is not limited to the embodiments presented or described above, but instead it can be modified in any suitable way within the basic idea of the invention according to purposes and embodiments at any given time.
  • the parts belonging to the mould arrangement according to the invention may ' be manufactured from most heterogeneous materials applicable for this purpose as one-piece or multiple-part structures.
  • the core can be coupled in its entirety or partly also with to the second auxiliary frame that is used in the mould arrangement for manufacturing of the fixed joining end.
  • the structures and implementations of the partial entireties belonging to the mould arrangement as well as flow assemblies to be coupled with the mould arrangement for injection moulding may naturally be carried out in most heterogeneous ways.

Abstract

La présente invention concerne un arrangement de moulure pour moulure par injection ; il est en particulier destiné à la fabrication de raccords de tuyaux ou leur équivalent qui sont faits de plastique et dont les dimensions et/ou les tailles diffèrent les unes des autres. Au moins une moulure partiellement interchangeable et/ou des surfaces centrales sont utilisées. L'arrangement de moulure se compose d'un socle de secteur (3) qui peut être placé dans un cadre de moulure (1) dans deux positions ou plus particulièrement pour permettre la fabrication de raccords de tuyaux comportant différents angles de joint par le biais d'un et du même cadre de moulure.
