The 10 Principles Of Tooling Design

  The 10 Principles of Tooling Design

  1, clamping force considerations

  The lateral clamping force of the mold is relatively small, so for large projects with large projection area, the direction of the projection area should be placed in the direction of the front and the 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, the location of the parting surface should be selected in the product section of the largest size, Tooling Design this is a basic principle.

  3, the shape of the sub-surface

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

  4, to ensure that the product appearance and quality

  Do not choose the surface of the product in a smooth surface. 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 of the requirements of all the same side, Tooling Design so as to ensure its concentricity.

  5, the direction of the determination

  In determining the product in the mold inside the orientation, the choice of sub-surface should try to prevent the formation of side or side of the product buckle, 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. Tooling Design So for some may stick to the fixed mold 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, 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 part should be designed in the plastic flow of the end, in order to facilitate the exhaust.

  10, R type

  For the Tooling Design classification of many products, Tooling Design sub-surface at a full circle of R angle, then the classification must take into account the R type of the best, can not appear sharp side.
