Definitions
- the invention relates to a device for demolding in sand cast mold bales of solidified castings, wherein the Sandg discernformballen are successively transported away from a Eing manposition on a support pad.
- the sand casting molds are conventionally run over a grate through which the molding sand falls off the castings. Non-self draining molding sand residues and sprues are removed manually.
- the invention has for its object to reduce the effort for demolding using sand cast mold bales produced castings.
- the castings can be automatically removed from the sand casting mold bales by the device according to the invention and kept ready for further processing in a defined starting position.
- the support base extends at least to a disintegration position of the sand mold bales in which the material of the sand mold bales drops from the casting received by the support rail.
- the disintegration position may e.g. be determined by an end edge of the carrier pad. Alternatively or additionally, shaking or pushing devices could be used at this point.
- a plurality of mutually parallel support rails are provided, wherein the castings are in particular suspended between the support rails, preferably via a gate widening, e.g. via a sprue cone produced by a funnel-shaped sprue opening.
- the castings can be easily pushed onto such a pair of retaining rails arranged at a distance from one another.
- the carrier pad can form a slideway on which the Sandg cordformballen are adjacent to each other displaced.
- a carrier support which itself is movable would be usable, e.g. a conveyor belt.
- the castings are slidably moved on the support rail as a result of the transport of the sand mold bales enclosing the castings.
- the trailing Sandg discernformballen push the exposed after disintegration of Sandg discernformballen then castings on the support rails on.
- the castings can be transported away beyond the other end of the carrier rail for further processing.
- the removal can take place with rotation of the castings about a vertical axis, by 90 °.
- the castings can be brought into a suitable position for further processing.
- the castings of a separating device for the separation of sprues can be supplied, wherein such a separator, for example, a shearing with a Includes die and a stamp.
- a separator for example, a shearing with a Includes die and a stamp.
- the punch pushes the casting, shearing the sprues through an opening in the die.
- Sandgitformballen 1 are transported on a support base 2 from a Eing manposition 3 in a row abutting each other according to arrow 4.
- the support base 2 forms a slideway on which the Sandg screenformballen 1 are advanced by means of a schematically indicated by an arrow 5 transport device cyclically.
- approximately cuboid Sandg screenformballen 1 is poured in the Eing manposition at 3 casting material, which is in the relevant embodiment to the production cast clutch plates for vehicle clutches.
- the solidifying in the Sandg discernformballen 1 castings 6 include in addition to the vertically inside the Sandg collectformballens extending clutch disc 7 Angusstraube 8 with a cone formed by a funnel-shaped sprue 9. At the transition points between the clutch disc 7 and Angusstraube 8 each have a predetermined breaking point 10 is formed.
- the Angusstraube 8 further comprises an extending in the transport direction approach 11, which serves as a spacer.
- FIG. 3 can recognize, adjoins the support rails 13,14 another processing device, which includes the sprue cone 9 attaching gripper 15, which take over the castings 6 of the support rails 13,14 and further transported according to arrow 16. During further transport, a 90 ° rotation of the castings 6 takes place about a vertical axis. The castings 6 then pass according to arrow 17 to a separating device 18, which includes a die 19 and a punch 20. The punch 20 moves perpendicular to the clutch disc 7 and pushes the clutch disc with shearing of the predetermined breaking points 10 through the opening of the die 19th
- subsequent further devices may further comprise vibrator means for shaking off residual molding sand, plasters or the like.
- the sprue cone 9 may have lateral flattenings, so that it can be held in rotation by the gripper 15 about the vertical axis.
