Definitions

  • the invention relates to a temperature control device for a mold of an injection molding machine, with at least one channel in the mold, for the flow through a heat transfer medium.
  • Temperature control devices which only provide hot water with different temperatures between 60 ° C. and 130 ° C. in order to adjust the temperature of the tool accordingly. However, this requires a long period of time if attention has to be paid to the necessary temperature changes in the workpiece because of the desired quality.
  • the object of the invention is to shorten the work cycle for the production of corresponding plastic parts while maintaining the desired quality of the plastic parts.
  • a temperature control device for a tool of an injection molding machine of the type described at the outset in that the at least one channel of the tool is connected to two media circuits, one of which serves as a cold circuit with a cold medium and the other as a warm circuit a warm medium can be loaded that both Circuits in the flow and return each have a controllable valve and that the two valves of the hot circuit can be bridged by a bypass valve.
  • a channel 2 is provided for the flow through a heat transfer medium.
  • This channel 2 is connected via a flow 3 and a return 4 to a source of a cold medium 5 or a cold water battery.
  • a controllable valve 6 or 7 is provided in both the flow 3 and the return 4, which are able to connect the respective flow or the return to the channel 2 or to separate it from the respective lines.
  • Another valve 8 binds a flow 9 of a warm circuit with the inlet line 10 for the channel 2, while another valve 11 connects a return 12 of the warm circuit with an outlet line 13 of the channel 2.
  • a temperature control unit of the hot circuit is designated 14.
  • a bypass valve 15 is provided between the valves 8 and 11 of the hot circuit, which With valves 8 and 11 closed, circulation of the hot medium is made possible because the warm circuit must not be interrupted due to the upper pressure.
  • valves 6 and 7 of the cold circuit are opened with closed valves 8 and 11 of the hot circuit, so that the valve 6 and the inlet line 10 cold medium into the channel 2 of the Tool arrive and can flow back to the cold water battery 5 via the line 13 and the valve 7 and the return 4.
  • the valves 6 and 7 of the cold circuit are closed and the valves 8 and 11 of the hot circuit are opened so that the tool can be heated to an appropriate operating temperature again.
  • the valve 15 is opened in order to enable a continuous circulation in the warm circuit.
  • the valve 15 is therefore a bypass valve.

Abstract

La présente invention concerne un dispositif pour réguler la température d'un outil d'une machine de moulage par injection, ledit dispositif comprenant un circuit de refroidissement (3, 4) qui, lorsque l'outil doit être refroidi, peut être mis en communication avec un canal (2) pratiqué dans l'outil (1), par des soupapes (6, 8) qui peuvent être commandées, le canal (2) de l'outil (1) pouvant, lorsque l'outil doit être à nouveau chauffé après son refroidissement, être mis en communication avec un circuit de chauffage (9, 12), par d'autres soupapes (8, 11). Comme le circuit de chauffage et son système de régulation de température (14) ne doivent pas être interrompus, une soupape de dérivation (15) est mise en place pour contourner les soupapes (8, 11).
