High precision custom-made low MOQ cylindrical Dowel pin one end female thread type for automatic equipment

The function of locating pin in mould

The role of the mold locating pin is mainly used in the screw fastening between two parts, through the locating pinto ensure the accuracy of position.Processing, group will be used

1, Its function is a reflection of the closed mold status inside the mold. Whether the mold has been put in place can be obtained by measuring the data between the upper and lower limit columns.

2, fixed pin limit column can also play a role in protecting the punch, when the upper and lower die separated limit column length is greater than the punch, to prevent the punch break.

3, When repairing the mold, the mold can be placed on the side to facilitate disassembly of parts. The limit column plays a role in protecting the mold, for example, the stripper or the concave template on the mold has the presser bar and the presser line to prevent the surface from being damaged when there is no material.

4, in the continuous mold, it is more important to protect the mold, to prevent the template in the high speed and long time of overload impact in the potential change;If the die is high precision (with many high bending requirements), it is even more necessary to install the limit column, because it can make the die in each stamping under the dead point is the same.

5, because of the effective limit of the mold travel, the protection of the punch, punch, so that the mold forming stability, and will greatly improve the quality of the product stability of the workpiece.

6, travel limit, will effectively prevent the material compression, especially aluminum and copper products
