The parting line is also called the parting line. It mainly depends on the design requirements and appearance requirements of the product, and also considers whether the processing is feasible and the position of the follow-up glue. No matter how the plastic product is parted, there will be obvious parting line marks. On the other hand, if you look at the parting line, you can know the structure of the mold. The following dragon resources tell you how to determine the parting line:
Determination of parting line
Before designing the parting surface, we 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 of the plastic part in that direction, you can use a straight line parallel to the mold opening direction to move along the outer contour of the object projection, and find Find out how the line intersects with the surface of the object at each location.
(1) If the straight line intersects the surface of the object at a point, the point is the point on the parting line.
(2) A straight line intersects with 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, specifically determining which point is used as a point on the parting line, generally it is adjacent to The shortest point connection is the principle. It can also be determined interactively.
(3) The 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 the core is designed for this area. The parting line should be determined according to the shape and size of the core .
