摘要： A bottom insert for an injection mold, which insert is of a two-part configuration having a hot part which has a recess of the hot side and a cold part which has a recess of the cold side, wherein the cold part is arranged at least partially within the hot part so that the hot part at least portion-wise surrounds the cold part. The two parts of the bottom insert are preferably separable and the. hot part preferably has an opening in opposite relationship to the recess of the hot side for receiving the cold part. Further, the cold part and the hot part are desirably sealed off relative to each other, desirably by O-rings. In general, all surfaces which are provided for contact with the molding to be produced are arranged at the cold part. An insulating coating, an insulating membrane and/or a spacing element is desirably provided at the contact surface between the hot part and the cold part.

摘要： An injection-moulding machine comprising a hot runner, arranged in a manifold, for feeding a melt into a mould, a shut-off needle for optionally closing or opening the hot runner, a piston connected to the needle, is arranged in a housing with an opening and to which a fluid can be applied from both sides, and a covering plate having two fluid feeds, into the opening wherein the covering plate, the hot runner manifold and the housing are arranged in such a way that, at a first temperature of the manifold, a distance remains between the housing and the covering plate and, at a second higher temperature the thermal expansion of the manifold and/or housing causes the housing to come into contact with the covering plate, closing the opening. In a further embodiment, a flexible seal is provided between the housing and the covering plate.

摘要： A bottom insert for a mold cavity for the production of moldings of plastic material. The mold cavity has a main body with a hot side which has a recess for receiving molten plastic material under pressure and a cold side having a recess, the inside contour of which is intended to come into contact with the molding to be produced and to shape the outside contour thereof. A gate (17) is provided that connects the recess of the hot side to the recess of the cold side and is intended to introduce molten plastic material from the hot side into the cold side. In accordance with the invention there is provided a device for thermal insulation within the bottom insert between the hot side and the cold side of the bottom insert to permit more rapid cooling of the cold side by restricting heat flow from the hot side.
