Parting line, also known as the parting line, mainly to see the product design requirements and appearance requirements but also take into account the plastic mold processing is feasible and the mold follow the position of glue. In any case, plastic mold products will have a more obvious parting mold marks, on the other hand, can tell the mold line to know the structure of the mold. Will Carter below to tell you how to determine the parting line:

Parting line to determine

Before designing the parting surface, you must first determine the shape and position of the parting line on the part. When the mold orientation is determined, it is easier to determine the parting line. Because, parting line in the mold in the direction of projection and plastic parts in the party

The projected outer contours coincide so that an outer contour projected along the object can be moved by a straight line parallel to the mold opening direction and the intersection of the straight line with the object surface at each position can be found.

(1) The straight line intersects the surface of the object at one point, then the point is the point on the parting line.

(2) The intersection of the straight line and the surface of the object in a straight line segment, then any point on this straight line segment can be used as the point on the parting line, which point is determined as a point on the parting line, Point connection is the minimum principle. It can also be determined interactively.

(3) The intersection of the straight line and the object at the multi-point and multi-section straight line indicates that the intersection of the global approach cone and the mold opening direction here is 0, so the design of core-pulling in this area should be determined according to the shape and size of the core .
