MCEN Herstellung von Bauteilen per Schleuderguss Trainingsset 2
This unit is designed for production of hollow bodies in a fast rotating die.
The unit is mounted on a thick steel sheet and hold by a frame of extruded and anodised aluminium, which provides a great stiffness and resistance.
This unit is made up of an electric motor, connected to a speed variator that will allow the modification of the motor turn velocity. On the motor axis, a pulley is mounted, which will transmit the rotational movement to the cast axis through a drive belt.
The cast axis is made of a 20mm. diameter stainless steel. The axis has got a pulley to receive the movement of the electric motor, whereas the cast is placed on the other end. The axis holds two intermediate supports made up of two units of bearings with supports made of casting materials. The unit has got rid ball bearings, with a spherical diameter to absorb a moderate lack of alignment between both supports. The axis is screwed on through two grub screws placed on the inner cap of the bearing.
The cast is cylindrical and is made of aluminium. The cast is closed on the left side with a lid adapted for the cylinder inside to avoid leaks of melted tin. This cast is pressed strongly into the axis through screws. On the right side, it holds a lied with a hole in which an unload tube for the crucible is put so that the melted metal falls into the cast. The cast useless length is 110mm., once the lids have been placed.
Both lids are dismantled to allow the extraction of the piece. For a later and correct assembly, marks of the cast on the outer side and on the lids should match one each other. Afterwards, screws should be pressed into.
The cast is made with a little cone-shape to make easier the extraction of the piece towards the inlet side.
