LINKAGE MECHANISM BETWEEN UNIAXIAL DIE OPENING AND CLOSING AND BOTTOM DIE LIFTING

摘要

The present invention relates to a linkage mechanism between uniaxial die opening and closing and bottom die lifting, comprising: a die opening and closing component, a lifting component, and a driving component driving the die opening and closing component and the lifting component to operate. The die opening and closing component comprises a bottom die, a fixed die plate disposed on a rack of a bottle blowing machine, and a moving die plate cooperating with the fixed die plate. The lifting component comprises a cam, a lifting rod, and a pulley fixedly disposed on a lower part of the lifting rod. A sliding slot capable of extending along an up and down direction is formed on the cam. The pulley is slidingly disposed inside the sliding slot. The bottom die is fixed on an upper part of the lifting rod. The driving component comprises a rotation shaft capable of rotating around its axis, and a power source driving the rotation shaft to rotate. The moving die plate and the cam can be fixedly connected to the rotation shaft at the same time. In the present invention, rotation of one rotation shaft is used to drive the die opening and closing component and the lifting component to implement linkage, so that the action problem is solved by using the simplest structure, the structure is simple, and the operation is convenient.
