The role of the positioning pin bai is to limit the free movement of the item. This free degree is that the object must have six degrees of freedom in space. The linear movement of the three axes of daox, Y, and Z and the movement around X and Y , Z rotation. It can't be fixed and can be removed after installation. Then there are two or more parts of the mold, the pin is the most widely used in the mold, including stamping mold, injection mold and so on. Moreover, the precision requirements of the stamping mold and the injection mold are very high. If bolts are used to fix the template, it is not enough. Therefore, only the pin is used to achieve the purpose of positioning. Or prevent the wrong installation position and direction. In addition, the pin has certain applications in many mechanical movement devices, which are mainly used for position determination based on two-dimensional space and so on.
