  The 10 principles of Tooling Design classification

  1, clamping force considerations

  The lateral clamping force of the mold is relatively small, so for large projects with large projected area, the direction of the projection area should be placed in the direction of the front and rear mold opening and closing modes, and the side projection area is smaller To the type.

  2, meet the product stripping requirements

  Parting surface is for the product can be successfully removed from the mold. Therefore, Tooling Design the location of the parting surface should be selected in the product section of the largest size of the site, which is a basic principle.

  3, the shape of the sub-surface

  General products, often with a injection molding machine to open the direction of vertical movement of the sub-surface, under special circumstances only the use of other shapes of the sub-surface. Tooling Design The shape of the parting surface to facilitate the processing and stripping principle. Tooling Design Like a certain bending of the product, when typing it had to listen to the curvature of its curvature.

  4, to ensure that the product appearance and quality

  Do not choose the surface in the smooth surface of the product. The appearance of the surface is generally not allowed to have a cable and other affect the appearance of the lines; some concentricity requirements of the product, have to have part of the concentricity requirements on the same side, so as to ensure its concentricity.

  5, the direction of the identified

  In determining the product in the mold inside the orientation, the choice of parting should try to prevent the product to form the side hole or side buckle, Tooling Design should avoid the use of complex mold structure.

  6, is conducive to stripping

  The general mold of the stripping mechanism are in the dynamic mode, so the choice of parting surface should be as much as possible after the mold to stay in the dynamic mode. So for some may stick to the fixed mode of the place, we tend to add fixed-mode auxiliary stripping mechanism.

  7, consider the lateral opening distance

  The general lateral mechanical open mold distance is relatively small. Therefore, when selecting the parting surface, the direction of the long distance should be selected in the direction of the front and rear mold opening and closing, Tooling Design and the short direction should be taken as the lateral type.

  8, mold parts easy to process

  Select the parting surface, the mold should be divided into easy processing of parts, reduce the difficulty of machining.

  9, conducive to exhaust

  When the parting surface as the main exhaust, the design should be part of the plastic flow in the end, in order to facilitate the exhaust.

  10, R type

  For the Tooling Design classification of many products, parting surface with a full circle of R angle, Tooling Design then the classification must take into account the optimal classification of R, can not appear sharp side.
