The parting line is also called the parting line, which mainly depends on the design requirements and appearance requirements of the product, but also considers whether the processing is feasible and the position of the mold to follow up the glue. No matter how the plastic product is parted, there will be more obvious parting line marks. Conversely, you can know the structure of the mold by looking at the parting line. The following Dragon Resources tells you how to determine the parting line:
Determination of parting line
Before designing the parting surface, you must first determine the shape and position of the parting line on the plastic part. When the mold opening direction is determined, it is easier to determine the parting line. Because the projection of the parting line in the mold opening direction coincides with the outer contour line of the projection of the plastic part in that direction, a straight line parallel to the mold opening direction can be used to move along the outer contour line of the object projection, and find Show the intersection of the line with the surface of the object at each position.


(1) The straight line intersects the surface of the object at a point, then this point is the point on the parting line.
(2) The straight line intersects the surface of the object in a straight line segment, then any point on this straight line segment can be used as a point on the parting line. It is specifically determined which point is the point on the parting line. Generally, it is the adjacent point The shortest point connection is the principle. It can also be determined interactively.
(3) The straight line and the object intersect at multiple points and multiple straight line segments, indicating that the intersection of the global approach cone and the mold opening direction is 0, so this area is designed for core pulling, and the parting line should be determined according to the shape and size of the core pulling .
