How to determine the making parts line during molding manufacture

Making Plastic Parts line is also called the parting line, mainly depends on the design requirements and appearance requirements of the product, and also considers whether the processing is feasible and the position of plastics mold to follow the glue. Plastic products will have obvious parting line marks anyway, and the mold line will know the structure of the mold. Let’s talk about how to determine the parting line:

Determination of making plastics parting line

Before designing the parting surface, it is first necessary to 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 projection of the plastic part in the direction, it is possible to move along the outer contour line projected by the object with a straight line parallel to the mold opening direction, and The intersection of the line at each location with the surface of the object.

(1) When the line intersects the surface of the object at a point, the point is the point on the parting line;

(2) If the straight line intersects the surface of the object in a straight line segment, any point on the straight line segment can be used as a point on the parting line, and specifically determine which point is used as the point on the parting line, generally with its adjacent The shortest connection is the principle. It can also be determined interactively;

(3) The straight line intersects the object in the multi-point and multi-segment straight line segments, indicating that the intersection of the global near cone and the mold opening direction is 0, so the design of the core is designed, and the injection making plastic part line should be determined according to the shape and size of the core.
