1. The customized machining workpiece of injection mold shall be positioned in a plane According to the number of degrees of freedom limited by the plane, there are three kinds: The main supporting surface limits the positioning plane of the workpiece with three degrees of freedom, and is often used for the positioning surface of the workpiece with high precision. A positioning plane that limits the two degrees of freedom of a workpiece, often made into a narrow and long surface. The thrust supporting surface limits the plane of one degree of freedom. In order to ensure accurate positioning, the plane area is often made as small as possible.

2. The customized machining workpiece of injection mold shall be positioned with round hole Long pin limit 4 degrees of freedom; Short pin limit 2 degrees of freedom.

3, injection mold customized processing workpiece cylindrical positioning Positioning datum is outer circle centerline. There are three kinds of common ones Positioning sleeve: to achieve centering positioning support plate: to the outer circle positioning V-shaped block: realize centering and centering of the outer circle surface.

The above is the method of how to choose the location of the original parts for injection Mold customized processing.
