[0002] The clamp ring is a kind of hardware tool, most of which are made by stamping. The clamp ring is divided into two categories: for shaft and for hole, and its cross section is rectangular and circular. It is usually called inner clamp ring and outer clamp ring. Its function is to position the parts and play an axial stop role. The stamping process of the clamp ring needs to be formed by a special mold.

[0003] In the process of clamp ring processing, a special mold for clamp ring forming is needed.

The utility model utilizes the different needs of the actual clamp ring forming processing, and places the raw materials required for the production of clamp rings of different models and specifications into the corresponding different diameter cavities for stamping and forming, so that the mold can simultaneously perform the forming processing of multiple types of clamp rings, greatly improving the overall efficiency of clamp ring forming.

[0004] However, the utility model clamp ring forming special mold realizes real-time ejection and discharge of the clamp ring by manually twisting the ejector rod to rotate in real time. Since the clamp ring and the inner wall of the cavity are adsorbed too closely during the forming process, the contact area between the ejector rod and the clamp ring is limited, which can easily lead to damage of the discharge material. In addition, the high discharge method is time-consuming and labor-intensive, which seriously affects the forming efficiency of the clamp ring and cannot meet the use requirements. Therefore, a clamp ring forming special mold is proposed to solve the above problems. Utility Model Content
