Hot runner plastic mold design procedure
  First of all, according to the structure and use requirements of plastic parts, determine the position of the feed inlet. As long as the structure of the plastic part allows, the nozzle and nozzle head in the fixed mold insert do not interfere with the molding structure, and the feed port of the Hot Runner System can be placed at any position of the plastic part. The position of the feed port for injection molding of conventional plastic parts is usually selected based on experience. For large and complex shaped plastic parts, the injection port position of injection molding can be used computer-aided analysis (CAE) to simulate the flow of molten plastic in the cavity, analyze the cooling effect of each part of the mold, and determine the ideal feed.

  Then, determine the nozzle head form of the hot runner system. The use characteristics of plastic parts materials and products are the key factors in selecting the nozzle head form, and the production volume of plastic parts and the manufacturing cost of the mold are also important factors in selecting the nozzle head form.

  Third, according to the production volume of plastic parts and the tonnage size of injection equipment, determine the number of cavities per mold.

  Fourth, the number of nozzles is determined by the determined feed port position and the number of cavities per die. If forming a product, choose a die one feed port, then only one nozzle, that is, a single-head hot runner system; if forming a product, choose a mold multi-cavity or a mold one cavity more than two feeds Multiple nozzles, that is, a multi-head hot runner system is used, except for the mold structure with a cross runner.

  Fifth, according to the weight of the plastic parts and the number of nozzles, determine the radial size of the nozzle. At present, the same type of nozzle has multiple size series, which can meet the requirements of forming plastic parts in different weight ranges.

  Sixth, determine the mold structure size according to the structure of the plastic parts, and then select the standard length series size of the nozzle according to the thickness of the fixed mold insert and the fixed template, and adjust the thickness of the template and other dimensions related to the hot runner system.

  Seventh, determine the shape of the hot runner fixing plate according to the shape of the hot runner plate, arrange the power line lead groove on the board, and design a sufficient cooling water loop near the hot runner plate, nozzle, and nozzle head.

  Eighth, complete the design drawing of the plastic mold of the hot runner system.
