Abstract

The temperature element (3) has an electrical resistance heating element (4) integrated in a high-heat conducting cooling body (5) i.e. aluminum-cooling body. The body and the heating element are insulated by a housing of the temperature element, where cooling of the body takes place by a fluid-like cooling medium e.g. water. The body is attached to the heating element based on constructional circumstances of the temperature element that is positioned under a surface area of a cavity (1). A controller of the temperature element is coupled to an injection molding machine controller.

Description

Aufgrund von Temperaturunterschieden werden die Eigenschaften bei der Herstellung von Kunststoffteilen stark beeinflusst. Das neue Temperierelement (3) gleicht in einem kunststoffformgebenden System (2) sekundenschnell diese Temperaturunterschiede aus. Zum heutigen Stand der Technik werden Temperiersysteme eingesetzt, die sehr langsam, nicht effizient und kostenintensiv sind. Das neue Temperierelement kann alleine oder mit mehreren solchen in einem System angeschlossenen Elementen in wenigen Millimetern unter der Kavität (1) eines kunststoffformgebenden Systems (2) eingesetzt werden und somit wird die Oberfläche der Kavität (1) auf eine gewünschte Temperatur erhitzt und abgekühlt und umgekehrt. Der Kühlkörper (5) wird am Heizelement (4) abhängig von konstruktiven Gegebenheiten so angebracht, dass eine bestmögliche Kühlwirkung im Heizelement (4) und an der Kavität (1) erzielt wird.Due to temperature differences, the properties in the production of plastic parts are greatly influenced. The new tempering element ( 3 ) is similar in a plastic molding system ( 2 ) within seconds these temperature differences. At the present state of the art tempering systems are used, which are very slow, not efficient and cost-intensive. The new tempering element alone or with several such elements connected in a system in a few millimeters below the cavity ( 1 ) of a plastic molding system ( 2 ) and thus the surface of the cavity ( 1 ) is heated to a desired temperature and cooled and vice versa. The heat sink ( 5 ) is applied to the heating element ( 4 ) depending on structural conditions mounted so that the best possible cooling effect in the heating element ( 4 ) and on the cavity ( 1 ) is achieved.

Temperierelement (3) besteht aus einem Heizelement (4), einem Kühlkörper (5) und einer Isolierung (6).Tempering element ( 3 ) consists of a heating element ( 4 ), a heat sink ( 5 ) and insulation ( 6 ).
