Title: Mould closing system - for injection moulding machine
IPC: B29C37/00
Filed: 1975-04-15
Abstract: Mould closing device for an injection moulding machine supported on guide rods, having a displaceable platen for one injection mould half which can be displaced by a drive system towards the stationary platen, at least one of the platens exposed to the mould closing pressure (the displaceable or the stationary platen or the counter bearing plate for the drive) being rigidly fixed to the free rod ends projecting through bores in the (bearing) plate, incorporating the improvement whereby (a) the diameter of the rods, at the place where they project through the plate is equal to the maximum diameter of the rods (b) the plate is pressed by the axial tension component of the screw thread in the direction of the free end of the rods onto an annular shoulder formed by a ring recessed into an annular groove in the associated rod. In particular, the screw thread is the external thread on a bolt engaging the internal thread on the movable platen and supported on a cap for the associated guide rod. The frequently asymmetrically loaded guide rods of the mould closing system offer a much greater resistance to bending, without the use of significantly greater amounts of material, and any unavoidable bending takes place over the major part or the whole of the rod and is therefore largely reversible.
