Definitions

  • the invention relates to a method for injection moulding of thermoplastic pole parts, with the use of a mould in which at least one vacuum interrupter and contact terminals are fixed during the moulding process, and with at least one injection opening/gate for injection of thermoplastic material into the mould, and mould for proceeding the same, according to the preamble of claims 1 and 9.
  • thermoplastic housing Injection moulding of medium voltage pole parts, for example to cover them with a thermoplastic housing is well known.
  • the proceding pressure for thermoplastic material during the moulding is higher.
  • thermoplastic housing One of the greatest advantages of thermoplastic housing is, that the manufacture times are shorter than the manufacture times for epoxy resin.
  • Reason for that is, that epoxy resin needs longterm curing periodes and slow temperature curves. Thermoplastic material only has to become solid by cooling down.
  • thermoplastic pole parts Injection moulding technology for thermoplastic pole parts is used only with single injection gate or opening.
  • the filling pressure decreases along flow path to low pressure at the end, caused by the viscosity of the thermoplastic material. This finally results in filling problems.
  • the maximum filling pressure inside the mould increases with height of the pole part or the pole part arrangement along the flow path.
  • Geometric constraints require inhomogeneous wall thickness along flow path, and therefore voids occur, and incomplete filling at dedicated pressures is the possible result.
  • thermoplastic covered pole parts are quite short, so dynamic effects like viscosity of the liquid hot
  • thermoplastic material occur during the process.
  • the mould is applied with multiple injection openings or gates or fim-injection gates at least along its long axis, for injection of hot thermoplastic material, and that the injection gates can be steared in such a way, that they inject thermoplastic material simultaneously or with a defined time dependend injection pattern.
  • An advantageous embodiment is, that further injection gates are located at that points in the mould where are located nonflat topography. This enhances a complete filling without time loss also at region with complicated topography. This furthermore results in a better mechanical as well as a better reduction of voids.
  • a further embodiment of the invention is, that the injection openings are applied with shutters, by which the flux of injected hot thermoplastic material can independently be steared for each injection opening.
  • shutters by which the flux of injected hot thermoplastic material can independently be steared for each injection opening.
  • the pressure in the injection openings or near to them are measured via pressure sensors in order to stear the injection of each injection opening e.g. each shutter according to a predetermined pressure gradient.
  • the injected hot thermoplastic material is filled with particles or fibres, and that at least dedicated injection openings are applied with that, in order, to strengthen at least several regions of the pole part.
  • the injection gates are steared or driven via the shutter and the applied pressure in such a way, that the direction of the resulting material flow in the mould during the moulding process can be steared or optimized.
  • the invention is, that the mould is applied with multiple injection gates at least along its long axis, for injection of hot thermoplastic material, and that at least one of the injection gates is applied with a steerable shutter.
  • the shutter or the injection means are steared by stearing means, in which a pressure and or flux pattern is
  • a further advantageous embodiment is, that in the injection gates or corresponding with them pressure sensors are located, and that the pressure sensor values are feed into the stearing means, in order to stear the shutter of injectors via a predetermined time/pressure pattern.
  • film injection gates can be used.
  • thermoplastic pole parts for indoor application are using multiple injection gates, in order to reduce viscosity-dependant pressure gradient along the long axis of the mould, so that it results in more homogenous housing of the pole parts and improve filling of the mould.
  • Figure 1 mould with several injection gates
  • Figure 1 shows in principle a mould , with several injections openings or gates along the logaxis, of the mould, which is as well the flow path of the injected thermoplastic material.
  • the inserted positioned vacuum interrupter because it is not need to display it.
  • the injection gates 1 , 2, 3, 4, 5 are applied in this case nearly equidistandly. But this is only an example, and it is not need in all cases to alligne them in that way in all cases. For example if regions of dense topography occur by given vacuum-interrupter- or inlay-construction the gates can be arranged nonequidistandly closes, that in other regions of the mould.
  • the effect of such an arrangement of injection gates is shown on the right side of figure 1.
  • the diagram shows the pressure gradient along the long axis or the flow path of the injected thermoplastic material.
  • Figure 2 shows according to figure 1 the comparison to the state of the art.
  • Figure 2 shows a mould with only one injection gate 1. It is clear, that the pressure decreases along the flow path of the thermoplastic material.
  • Figure 3 shows an embodiment in case of the use of additional inlays in the mould.
  • This additional inlays can be the electric terminals of the pole part. So the injection gates are located in such, that they are positioned near to that inlays.
  • the injection gates 1 , 2 are furthermore positioned in that way, that a force F, is caused by injected material in that way and in that direction, that the inlay will be pushed into its predetermined end position. This gives a high performance in sense final measures and positioning of the manufacture of a pole part.
  • a location of injection gates will be selected in such a way, that a maximum filling pressure is reduced compared to single injection gate, and the flow of material is much more homogenous in sense of high mechanical performance of the housing of the pole part. Furthermore a control of maximum filling pressures is possible, in order to consider each pressure sensitive inlay in such a pole part. The control of pressure profile along flow path is also possible, at least to consider several topography of the inlays, or of the outer surface of the pole part housing.
  • FIG. 4 shows schematically an embodiment in use of the invention in case of general or additional film injection method. Also in this case the invention is implemented. Film injection gates 1 , 2, 3, 4, 5, 6 can be applied from the inner and/or the outer side of the mould.
