FLOW RESTRICTOR FOR INJECTION MOULDING MACHINE FOR THE INJECTION MOULDING OF RUBBER MATERIALS OR OF ELASTOMER MATERIALS

摘要

The present invention relates to a flow restrictor for an injection moulding machine for the injection moulding of rubber materials or of elastomer materials, and comprises a flow restrictor module, an in-flow channel and out-flow channel provided therein, and also a flow restrictor device. The in-flow channel can have been provided at an angle with respect to the out-flow channel. The flow restrictor device comprises a flow restrictor piston which more particularly serves not only for restricting the flow of the material but also for injection of the rubber material or of the elastomer material into the injection mould. Use of the inventive flow restrictor can give a system and method for the temperature control of rubber materials or of elastomer materials during injection moulding, and this more particularly can achieve shorter cycle times.
