Problems solved by technology

[0008] However, the reason why heating methods for replacing steam heating have not been successfully applied so far is that uniform and complete heating of rubber products cannot be satisfactorily achieved.

Embodiment Construction

[0028] The press here has a frame 2 in which a top part 5 and a corresponding bottom part 6 are formed for each of the dual-curing molds 3 , 4 . The top part 5 is arranged movably in the machine frame 2 and is moved in each case by means of a press cylinder 7 . Bottom part 6 is firmly connected with this frame with screws.

[0029] As a result, the corresponding top part 5 can be moved into the open position of the curing mold 3 shown on the left and into the closed position 4 shown on the right. The blank 8 of the air spring bladder to be cured is inserted into this open position 3 . The curing mold 3 is then closed and curing of the air spring blank can be started, ie heating of the curing mold can be started. For example, in this state is the curing mold 4 shown on the right.

[0030] The curing molds 3 and 4 are provided with means for bringing the air spring blanks into contact with the curing mold parts, i.e. with means not shown in detail here, by means of which the ...

Abstract

The present invention relates to a method for curing blanks made of elastomeric materials, wherein the blank to be cured is heated to a curing temperature in a metal curing mold containing the blank and is transferred by heat from the curing mold heated by electric induction The blank is heated, wherein the curing mold is heated via at least two electrically coupled coupling coils arranged coaxially at the ends of the curing mold and through which a high-frequency alternating current flows.

Description

technical field [0001] The invention relates to a method for curing objects made of elastomeric material, wherein a blank to be cured is heated to a curing temperature in a metal curing mold containing the blank. A device for carrying out the method as well as specific applications of the method are likewise disclosed. Background technique [0002] Typically, products made of elastomeric materials are cured using hot steam. In this case, superheated steam is generated in the boiler room by means of a gas burner system and then conveyed via a widely branched pipeline system to the curing press in the factory. In curing plants / curing presses, the steam is used to heat the curing mold and its components and components or to rinse the mold parts. The generation of steam is very expensive and there is a considerable energy loss due to extensively branching piping before the steam reaches it during the actual heating process. Here, for example, it is necessary to insulate all l...
