Punching machine mold stable in mold assembly

Abstract

The invention discloses a punching machine mold stable in mold assembly, and belongs to the technical field of mechanical production devices. A guide rod and a buffer rod are fixedly mounted on one surface of an upper mold, the other end of the guide rod is slidingly sleeved with a lower mold, the surface of the lower mold is provided with a buffer hole, the bottom of the buffer hole is provided with a thread hole, the thread hole is connected with a fastening rod through a thread, the other end of the fastening rod is fixedly connected with a buffer block, the other face of the lower mold isfixedly provided with a lower mold plate, the other surface of the lower mold plate is provided with a through hole and an upper clamping groove, the buffer block of the machine mold is located in thebuffer hole, when the buffer block is extruded by a buffer rod, the buffer block cannot deflect, work intensity of the guide rod can be prevented from being increased, the buffer rod has the guide effect, the mold assembly stability of the machine mold can be improved, a mold holder is mounted, rapid setup of the machine mold is facilitated, a clamping base has the anti-sliding limiting function,and the mounting firmness of the machine mold can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of mechanical production devices, more specifically, to a stamping machine mold with stable mold clamping. Background technique [0002] A mold is a tool used to make shaped objects. This tool is composed of various parts. Different molds are composed of different parts. It mainly realizes the processing of the shape of the object through the change of the physical state of the formed material. [0003] At present, most of the existing stamping machine molds with stable mold clamping protrude the buffer block from the surface of the lower mold, so the buffer block is squeezed and deformed when the mold is closed, which may cause a slight skew of the upper mold , thus increasing the working strength of the guide rod. If things go on like this, it will lead to deformation of the guide rod and reduce the mold clamping stability of the mold. Moreover, the existing mechanical mold is time-consuming when setting u...

Problems solved by technology

[0003] At present, most of the existing stamping machine molds with stable mold clamping protrude the buffer block from the surface of the lower mold, so the buffer block is squeezed and deformed when the mold is closed, which may cause a slight skew of the upper mold , thus increasing the working strength of the guide rod. If things go on like this, it will lead to deformation of the guide rod and reduce the mold clamping stability of the mold. Moreover, the existing mechanical mold is time-consuming when setting up the mold, and after the completion of the mold setting, the lower mold is long. The influence of vibration force over time may lead to slight movement, which greatly reduces the firmness of the mechanical mold frame
