The Main Design Points Of Automobile Lamp Reflector Mold

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) The reflector plastic part is a device for preventing the direct light, reflecting the light and avoiding the direct light on the car lamps, and the light distribution requirements are strict. Plastic parts are the most important appearance parts of automobiles. There are many patterns on the surface of plastic parts for the purpose of decoration and beauty.

(4) The ejection system of BMC material mold design shall be balanced, and the push rod specification shall be designed as large as possible and the number shall be as large as possible, otherwise it will cause difficulty in demoulding plastic parts.

(5) Because it is difficult to demould the high photoelectric plated parts because the demoulding slope is too small, the side wall demoulding slope of the mirror plastic parts should be designed as large as possible, generally recommended to be 5 °~10 °. Of course, the premise is that the function and shape of the plastic parts cannot be affected.

(6) Plastic parts shall not have sharp corners and sharp edges, and all corners shall be designed as rounded corners, because the formed parts of the die are prone to stress cracking after quenching.

(7) Note that the left and right reflector lamp cap holes and the pattern on the surface of the plastic parts are translated from side to side, and cannot be designed to be mirror symmetrical, because the bulb and lamp cap are not left and right, and the other features are mirror symmetrical.

Eight common injection mold structure classification One. Single parting surface injection mold When the mold is opened, the movable mold and the fixed mold are separated, so as to take out the plastic parts, which is called single parting surface mold, also called double-plate mold. It is the simplest and most basic form of injection mold, which can be designed as single-cavity injection mold or multi-cavity injection mold according to the need, and is the

The difference between injection moulds and plastic moulds Many people can’t tell the difference between injection molds and plastic molds, and many people even think that they are the same kind of molds, just called different. Although injection molds and plastic molds are both molds, but there is a difference between them. Want to figure out the difference between the two, first and Xiaobian together to understand what is injection mold, what is plastic mold.
