摘要： Injection molding machines must be provided with devices which ensure that the mold mounting plates when in open position cannot inadvertently close, wherein the conventional safety devices include a toothed locking bar disposed between two mold mounting plates and are provided with a ratchet mechanism, but which obstructs accessibility in the space between the two mold mounting plates, so that according with the present invention a blocking unit is disposed outside the space between two mold mounting plates for engagement of the drive unit of the closing unit to thereby prevent an inadvertent closure.

摘要： A plasticizing barrel for a plastics processing machine includes a body having a hollow cylindrical configuration and defining an axis; and a coating formed on an inner wall surface of the body and including at least one groove extending in axial direction of the body. The coating, e.g., a wear-resisting protective layer, may be produced through centrifugal casting, whereby the grooves are formed by projections of a negative mold inserted in the hollow-cylindrical body.
