Injection mold, molding tool comprising the mold and methods of use thereof

An injection mold comprising:

• an injector mold plate having a first injector mold plate face including first mold cavities halves of one or more first mold cavities and an opposite second injector mold plate face to be mounted to an injection molding tool, an ejector mold plate having a first ejector mold plate face including second mold cavities halves of one or more second mold cavities and an opposite second ejector mold plate face to be mounted to an injection molding tool, the first injector mold plate face faces towards the first ejector mold plate face to delimit the one or more of the first and second mold cavities when the injector mold plate and the ejector mold plate are in closed contact during injection of a plastic material, at least one tempering medium channel that connects at least a tempering medium inlet of the injection mold to a tempering medium outlet of the injection mold, the at least one tempering medium channel defining a flow path that runs above one or more of the one or more of the first and second mold cavities by traversing an area of the second injector mold plate face and of the second ejector mold plate face, the at least one tempering medium channel also defining a free opening in said respective second mold plate face, wherein each of the injector mold plate and the ejector mold plate comprises of the at least one tempering medium channel, wherein each of the tempering medium channel is configured as a single continuous chicane of tight turns defined by channel walls configured to minimize turbulence and has a lengthwise opening along its entire length, which opening becomes closed when the injection mold is mounted to an injection molding tool, a first sealing plate that is sealingly securable to the second injector mold plate face, a second sealing plate that is sealingly securable to the second ejector mold plate face, a first insulating plate that is disposed on the first sealing plate facing the second injector mold plate face, and a second insulating plate that is disposed on the second sealing plate facing the second ejector mold plate face, wherein the at least one tempering medium channel of the injector mold plate is closed by the first sealing plate and the at least one tempering medium channel of the ejector mold plate is closed by the second sealing plate when the injection mold is mounted in an injection molding machine that is configured to provide alternate heating and cooling to both the injector mold plate and the ejector mold plate during a molding cycle, wherein the injector mold plate, the first sealing plate, and the first insulation plate are detachably clamped tight together, and wherein the ejector mold plate, the second sealing plate, and the second insulation plate are detachably clamped tight together.
