摘要： A process for the injection molding of objects having an outer layer of enamel and an inter layer of a plastic material is disclosed. According to the process, a liquid enamel is used. This enamel is injected by an enamel-injection apparatus through an enamel-injection die. A plastic melt passes through an injection unit into the cavity. According to the invention, the liquid enamel is injected into the flow path of the melt in the region before the cavity, before the melt is injected, so that the melt is encased by enamel before it is distributed in the cavity. Variations are also disclosed. For example, the form can be filled with enamel and the excess enamel drained. Then, the melted plastic material is introduced into the injection molding form. Also, the form can filled and then the capacity of the form increased to accommodate the melted plastic material. In any case, it is possible to use liquid enamels to enamel injection molded parts in the tool or form. Furthermore, the inventive process makes possible a rapid and therefore economical mode of operation.

摘要： A method for injecting plastic material or another injectable material into an injection molding tool comprises the following steps: plasticizing the plastic or other injectable material in a plasticizing apparatus (2); transporting the plasticized plastic or the plasticized other injectable material into a dosing apparatus (3), which has a fluidic connection (4) to the plasticizer apparatus (2), and specifically in essentially precisely the quantity that is to be introduced into the injection molding tool (1); transporting the plasticized plastic or the plasticized other injectable material, essentially in that quantity which is to be introduced into the injection molding tool (1), from the metering apparatus (3) into an injection apparatus (5), via a fluidic connection (6), while at the same time preventing the plastic or other injectable material from backflowing from the metering apparatus (3) into the plasticizing apparatus (2); injecting the entire quantity of plastic or the entire quantity of another injectable material, which is situated in the injection apparatus (5), into the injection molding tool (1), while at the same time preventing the plastic or the other injectable material from flowing from the injection apparatus (5) back into the metering apparatus (3). In this way the production of small and ultra-small injection molded parts is facilitated, and the injection of a reproducibly precise quantity of melt is accomplished.

摘要： A changing device for the screw cylinder of an injection molding machine. The screw of the screw cylinder is in releasable coupling connection with a drive unit of the machine. For releasing and uncoupling the coupling connection, the screw cylinder including screw can be displaced relative to the injection molding machine essentially transversely of the longitudinal direction of the screw cylinder. Two hydraulic cylinders are arranged spaced apart next to each other symmetrically and parallel to the longitudinal center plane of the injection molding machine. The two cylinders are connected to each other by means of a transverse member. A free space extending forwardly from the drive unit is defined by the two hydraulic cylinders and the transverse members. The free space forms an alignment seat which is open towards the front and towards the back and a longitudinal side. In the coupled position, the screw cylinder is fixable and lockable to the drive unit in this alignment seat. The free space forming the alignment seat of the changing device is open toward the bottom, so that the transverse member which connects the hydraulic cylinders acts on the upper longitudinal side of the hydraulic cylinders.
