The role of the positioning pin
Locating PinThe function is to limit the free movement of the object. This degree of freedom is that the object must have six degrees of freedom in space, the linear movement of the three axes of X, Y, and Z and the rotational movement around X, Y, and Z. It does not have a fixed effect and can be removed after installation.
Then there are two or more parts of the mold, the most widely used in the mold pin, including stamping mold, injection mold, etc., and stamping mold and injection mold for precision requirements are very high, if only the use of bolts to fix the template is completely not enough, so only with the pin to achieve the purpose of positioning.
Or to prevent the installation position, direction of the error, in addition, the pin in many mechanical movement of the device has a certain application, which is mainly used to determine the position based on two-dimensional space and so on.
Locating PinThere are five kinds of fixed type, replaceable type, cone surface, chamfered edge and standard diamond. Generally, this kind of parts are sold point-to-point. The positioning pin standards include cylindrical pin GB.T119.1-2000,GB/T119.2-2000, internal thread cylindrical pin GB/T120.1-2000,GB/T120.2-2000, and taper pin GB/T117-2000.
Locating PinThe specifications are 3 to 50mm fixed pin and so on. Since the pin needs to clamp the workpiece repeatedly in the process of use, the pin shaft is required to have good wear resistance, so the better material to be selected is T10A or No. 20 steel, and the technical requirements for the material are sharp corners, anti-rust treatment, heat treatment, etc.
Locating PinThe positioning effect is very good, and it is very convenient to install. The box seat and the box cover are positioned by conical pins and fastened by bolts, which makes it very convenient to uncover the box cover.
It should be noted that the mold must be correctly synchronized when closed to make a perfect product, and the pin can help the upper and lower molds to be positioned in a precise position, thus ensuring the quality of the product.
However, each kind of parts needs careful maintenance, so buyers must pay attention to the storage conditions and instructions of the parts when purchasing the positioning parts, so as to ensure that each pin can be used well.
