[0001] The utility model relates to the technical field of molds, in particular to a device for quickly measuring the outer circle angle of a mold. Background Art

[0002] Cold heading dies, also known as steel dies, refer to dies used for cold heading. This type of die is a process that uses a die to cold-work and deform metal materials at room temperature. Since the temperature of cold working is lower than that of hot working, it can ensure that the strength and hardness of the product are higher, and no heating treatment is required during the processing, which is energy-saving and environmentally friendly; since the deformation amount of cold working is relatively large, it is necessary to use high-hardness and high-strength steel to make the die.

[0003] In the production of cold heading dies, some mold parts have a certain taper in shape. During the production process, the outer circle inclination angle of the mold parts needs to be frequently controlled to avoid exceeding the requirements. However, the measurement of the outer circle inclination angle is difficult for production personnel. Therefore, a device is needed to quickly determine whether the angle of the mold parts is qualified. The mold parts are hereinafter referred to as "test parts". Utility Model Content
