The function of the positioning pin is to limit the degree of freedom of movement of the object. This degree of freedom means that the object must have six degrees of freedom in space, linear movement in the three axes of X, Y, and Z, and rotation around X, Y, and Z. movement. It does not have a fixing effect and can be removed after installation.
Then, among the molds composed of two or more parts, pins are the most widely used in molds, including stamping molds, injection molds, and so on. In addition, stamping molds and injection molds have very high precision requirements. It is not enough to use bolts to fix the template. Therefore, only pins can be used to achieve the purpose of positioning.
Or to prevent the wrong installation position and direction. In addition, pins have certain applications in many mechanical motion equipment, and they are mainly used to determine positions based on two-dimensional space, and so on.
