Parting line, also known as the parting line, mainly to see the product design requirements and appearance requirements but also consider the feasibility of processing and molding follow-up plastic position. In any case, plastic products will have a more obvious parting mold marks, on the other hand, can see the mold parting line to know the structure of the mold. The following dragon resources for everyone to say how to determine the mold 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. Since the projection of the parting line in the mold opening coincides with the projected outer contour of the plastic part in this direction, it is possible to move along the outer contour projected by the object with a straight line parallel to the mold opening direction The straight line in each position and the intersection of the surface of the situation.

(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 points on the parting line, which point to determine specifically as the points on the parting line, generally with its adjacent 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 shows that the intersection of the global approach cone and the mold opening direction here is 0, so the core design should be designed. The parting line should be determined according to the shape and size of the core .
