For the automobile lamp reflector mold, the main design points are: (1) Special injection molding process equipment is required, and injection molding machines specialized in producing BMC plastics are used. The requirements for injection molding process equipment are very strict. (2) BMC material belongs to super hard plastic. In mold design, heating system and parting surface layout system need to be designed. Molding parts must be quenched to improve wear resistance and mold life. (3)

During injection molding, there will not be a lot of molten materials oozing from the vent hole, because the molten materials will be cooled and solidified there to block the channel. The opening position of the exhaust port shall not face the operator to prevent accidental ejection of molten materials from injuring people. In addition, the fit clearance between the ejector rod and the ejector hole, the fit clearance between the ejector block and the

Basic Principles of Injection Mold Gating System Design   1. Consideration of cavity layout 1) Balances Layout shall be adopted as far as possible; 2) The mold cavity layout and gate opening shall be symmetrical as far as possible, so as to prevent the uneven force of the mold from generating eccentric load, which may lead to the problem of mold overflow; 3) The mold cavity layout shall be as compact as possible to reduce
