Use the standard mold: standard mold size series of many, should choose the right size. If the size is too small, may make the mold strength is not enough, but also causes the screw hole, pin hole, guide pin guide sleeve position not too big in size, selection of formwork, not only cause cost increase, and may make the injection molding machine models.Design style frame selection and plastic parts of the size, shape and mold designers, mold manufacturing with production equipment.
  1.determine the die set assembly form, in the injection mold structure, first of all should be based on the cavity shape, cavity layout, gating system to determine the overall structure of the mold is choice mold combination form.
  2.determine the cavity wall thickness, through the calculation of relevant experience or relevant data sheet thickness, to get the cavity wall thickness.
  3.cavity template perimeter, according to the cavity length, width and the cavity wall thickness to determine the cavity templates perimeter size. The cavity size and thickness is the choice of template perimeter frame key.
  4.Size template boundary, the calculation of income on the step stencil perimeter is unlikely to be the same size and standard template, choose a larger value by calculating the size to the standard template size. The template must have the enough position, to install other components. If not enough, to meet the requirements by increasing the wall thickness.
  5.determine the stencil thickness, thickness of stencil set to the depth of the decision by the strong.
  6.Size choice mold, according to the defined template border size, with the stencil thickness check standard, select the mold.
  7.The test of the selected frame, check the relationship between formwork and injection molding machine, such as not suitable for the need to re select.
