1) Plastic mold cavity number and arrangement. When the plastic parts design is complete and after the materials selected, you need to consider is the use of single or multi-cavity mold cavity mold.
    Determine the number of cavities to be considered:
    1, the plastic parts of the batch and delivery cycle.
    2, the quality control requirements.
    3, molded plastic parts and plastic varieties of shapes and sizes.
    4, the cost of plastic parts.
    5, the layout of the cavity.

    2) plastic mold parting surface of choice. Sub-surface plastic parts should be selected in maximum contour shape; determining a favorable way to retain facilitate the smooth release of plastic parts; guarantee the accuracy requirements of parts; plastic parts meet appearance requirements; easy to mold manufacturing; help improve exhaust effects; help side Pulling.
    Design gating system and overflow discharge system, ordinary runner gating system generally consists of four parts sprue, runner, runner and cold-slug and other components. Gating system design is reasonable not only a great influence on the performance of plastic parts, structure, size, internal and external quality, but also the utilization of plastics and plastic parts used in molding production efficiency and so on. Drain overflow system is mainly air and plastic heating excluded cavity or solidified low molecular weight volatiles produced gas, there are usually four ways:
    1, the use of exhaust gas with the gap.
    2, open the exhaust vent at the parting groove.
    3, using an exhaust vent plugs.
    4, the mandatory exhaust.
