  • Publication number: 20230396058
    Abstract: An in-mold lid closing apparatus includes a lid engagement member, a first actuation assembly connected to a first portion of the lid engagement member, a second actuation assembly connected to a second opposing portion of the lid engagement member, and a controller disposed in electrical communication with the first actuation assembly and the second actuation assembly. The controller is configured to transmit a first drive signal to the first actuation assembly and a second drive signal to the second actuation assembly to drive one of a linear position and a rotational position of the lid engagement member and to adjust at least one of the first drive signal and the second drive signal based upon a first feedback signal received from the first actuation assembly and a second feedback signal received from the second actuation assembly.

  • Publication number: 20210060838
    Abstract: A threaded mold decoupling system comprises a set of unscrewing assemblies, each unscrewing assembly disposed in proximity to a corresponding threaded core of a set of threaded cores and having an unscrewing element defining an unscrewing element circumference and a driving element disposed in operative communication with an unscrewing assembly of the at least one set of unscrewing assemblies. The driving element defines a driving element circumference, a ratio of the driving element circumference to the unscrewing element circumference defining a number of rotations of each unscrewing element relative to a number of rotations of the driving element. The driving element is configured to rotate each unscrewing element in a first direction between a first position and a second position to decouple each threaded core from a corresponding molded article and in a second direction between the second position and the first position to reset each unscrewing assembly.
