1. The customized processing workpieces of the injection mold are positioned on the plane, which are divided into three types:
(1) The main bearing surface restricts the three-degree-of-freedom positioning plane of the workpiece, which is often used for the positioning surface of the workpiece with relatively high accuracy.
(2) The guide bearing surface restricts the positioning plane of the workpiece with two degrees of freedom, and is often made into a narrow and long surface.
(3) The thrust bearing surface restricts a plane with one degree of freedom. In order to ensure accurate positioning, the plane area is often made as small as possible.
2. Customized processing workpieces of injection molds are positioned with round holes
Long pins limit 4 degrees of freedom; short pins limit 2 degrees of freedom.
3. Positioning outside the cylindrical surface of the injection mold custom processing workpiece
The positioning datum is the centerline of the outer circle. There are three commonly used
Positioning sleeve: realizing centering positioning Support plate: positioning the outer circle
V-shaped block: to achieve centering and positioning of the outer circle surface
