Description

Technical Field

[0001] The utility model relates to the technical field of foaming molding machines, in particular to an EVA sole secondary foaming molding machine. Background Art

[0002] Foam molding machines are used in the field of chemical production. Foam molding machines are used for foam molding.

This technical solution has accurate positioning, simple operation, and high processing efficiency. The rotation of the servo motor can drive the rotation of the worm, thereby driving the rotation of the rotating gear, and then driving the rotation of the rotating disk. The extension and retraction of the third electric telescopic rod can drive the lifting and lowering of the rotating disk and the limit rod. The position and height of the limit rod can be limited by the limit block and the limit groove, thereby playing the role of fixing the rotating disk. The first electric telescopic rod, the servo motor, the second electric telescopic rod and the third electric telescopic rod are controlled by the PLC controller, which can achieve simple and efficient operation and processing.
