Method and Device for Demolding Annular Elastomer Moldings from a Mold Core |
| 摘要 |
The invention relates to a method and a device for demolding annular elastomeric molded parts from a mold core of an injection mold which has an inner mold core (1) and outer mold jaws and in which the molded parts (9) are produced parallel to one another in annular mold cavities (5) of the mold core (1). According to the invention, after removal of the outer mold jaws, the mold core (1), which contains the produced elastomeric molded parts (9) on the surface thereof, is set at such a high rotational speed about the longitudinal axis thereof that the internal diameter of the elastomeric molded parts (9) is increased because of centrifugal force to such an extent that the molded parts (9) are released from the mold cavities (5) and can be removed from the mold core (1) in the axial direction (10) while they are still rotating. |

1. A method for demolding annular elastomeric molded parts from a mold core of an injection mold which has an inner mold core (1) and outer mold jaws and in which the molded parts (9) are produced parallel to one another in annular mold cavities (5) of the mold core (1), characterized in that, after removal of the outer mold jaws, the mold core (1), which contains the produced elastomeric molded parts (9) on the surface thereof, is set at such a high rotational speed about the longitudinal axis (12) thereof that the internal diameter of the elastomeric molded parts (9) is increased because of centrifugal force to such an extent that the molded parts (9) are released from the mold cavities (5) and can be removed from the mold core (1) in the axial direction (10) while still rotating. |
