A tool for injection molding plastic parts includes a static overall frame and two structural units for forming a cavity. One of the structural units is arranged displaceably relative to the overall frame and the other structural unit in order to remove an injection-molded part from the cavity. The static overall frame is formed by at least two frame units, in particular a first ejector-side tool element and a second nozzle-side tool element, which are displaceable relative to one another, but in the production mode are displaceable within the scope of the elasticity, which is preferably less than a millimeter.

An injection molding machine device includes at least two guide rods. One end of each guide rod is fixed to a rack, and the other end of each guide rod is fixed to a fixed base body. A movable base body is provided opposite to the fixed base body. The movable base body slides along the guide rods relative to the fixed base body. At least one correction mechanism is located between the movable base body and the guide rail to adjust a movement of the movable base body in a vertical direction. A predetermined clearance value and/or a predetermined contact force value exist between the components. At least one sensor is electrically connected to a controller. The controller correspondingly controls the correction mechanism by determining whether corresponding detecting values of the sensor match with the predetermined clearance values and/or the predetermined contact force values.

A spout (1) for a flexible pouch (100) for liquid food, such as fruit juices, yogurt, fruit or vegetable purees and the like, includes a tubular barrier (30) embedded in the tube (18), made of a material impermeable to atmospheric oxygen. The spout is made by molding equipment that includes a counter-mold (300) with fixed insert (302) and a movable skirt (304), slidably fitted on the fixed insert (302). The spout may be made by a production method in which, during the injection of a first oxygen permeable plastic material, the skirt (304) is moved, coming out of the barrier (30), which remains in a fixed initial position.

Rubber injection molds are provided. A rubber injection mold includes a binary form-stripping mold, a trinary form-stripping mold, and a quadruple form-stripping mold. The binary form-stripping mold can include an upper mold and a bottom mold movably connected to each other via a guide post. The trinary form-stripping mold can include an upper mold, a bottom mold, and a middle plate positioned between the upper mold and the bottom mold. The upper mold and the bottom mold movably connected to each other via a guide post welded to the bottom mold. The quadruple form-stripping mold can include an upper mold, a bottom mold, a middle plate, and a middle frame. A guide post is welded to the bottom mold. Side rails can be respectively arranged at two ends of the upper mold and the bottom mold. Upper mold handles are fixedly mounted in the side rails of the upper mold.
