How to determine the mold line in the mold manufacturing process?

Parting line, also known as parting line, mainly depends on the design requirements and appearance requirements of the product, but also takes into account the feasibility of processing and the location of the mold following glue. Plastic products will have a more obvious parting line mark anyway, and conversely, the structure of the die can be known by the parting line. The following dragon resources tell you how to determine the parting line:

Determination of the mold line

Before designing the parting surface, the shape and location of the parting line must first be determined. When the direction of the die is determined, it is easier to determine the parting line. Because the projection of the mold line in the direction of the die is coincided with the outer profile of the projection of the plastic part in the direction, so a straight line that is parallel to the direction of the die can be moved along the outer surface of the object, and the intersection of the line to the surface of the object is obtained.

(1) when a straight line intersects the surface of the object, it is the point on the parting line.

(2) the line is intersected with the surface of an object in a straight line, then any point in this line can be used as a point on the parting line, which is to determine which point is the point of the parting line, and generally the shortest connection with the adjacent points is the principle. It can also be determined by an interactive way.

(3) the line is intersected with the object in a multipoint and multi segment line. It shows that the intersection of the global approach cone and the direction of the open die is 0, so the core is designed in the region, and the mold line should be determined according to the shape and size of the core pulling.
