Quick mold change mechanism

Abstract

The present invention provides a quick die changing mechanism, which relates to the technical field of die changing of cold heading machines, including a cold heading machine body, a punch die quick die changing assembly and a main die quick die changing assembly. The cold heading machine body includes a main slide, a punch die and a main die. The main slide is installed on the top surface of the cold heading machine body, the punch die is arranged on the right side of the main slide, and the main die is correspondingly arranged on the right side of the punch die. The present invention pulls the punch die out of the workpiece through the punch die pull block, drags it into the die changing frame, and then lifts the die changing frame away to complete the mold removal. Conversely, the mold can also be installed in the workpiece of the equipment to achieve quick mold change, which is more convenient than manual replacement and has less safety hazards in the production process. In addition, the designed mold box positioning pin groove and fuselage positioning pin groove are used to adjust the front and rear and left and right positioning of the die changing frame, so that the position of the die changing slide rail matches the mold, thereby making the installation and replacement of the mold more convenient and improving the production efficiency of the overall device.
