What should pay attention to when designing the car light mold

   The headlight mold is composed of two symmetrical products.Generally, there are reverse buckles, and the order of mold opening is also particular. Among so many headlights, headlights are difficult to make. Let ’s take a look.

       A fast curved surface of the lamp reflector bowl or a curved surface on the transparent cover is useful. Each curved surface has an equation, and the intersection between the surface and the surface must be guaranteed, including later polishing. If the polishing removes the intersection, then the mold will be finished, so polishing is very important, and the polishing must be uniform. Therefore, the design of the mold must ensure that the curved surface conforms to the theoretical curved surface. Otherwise, the light from the car light is unqualified.
       First, the car light is used as a typical plastic mold. The parting surface, reference surface and gate position, mold cavity shape, size, surface finish, parting surface, inlet and exhaust slot positions, and demoulding methods are used to control the mold. The dimensional accuracy and shape accuracy of the part, as well as the physical properties, mechanical properties, electrical properties, internal stress, isotropy, appearance quality, surface finish, air bubbles, dents, burnt, silver streaks, etc. important influence.
      Secondly, reasonable cavity design, ejection ejection system and simple and applicable, stable and reliable mold structure can improve the production efficiency of plastic products, shorten the production cycle and reduce production costs.
      Different uses of automobile headlights have different standards. Among them, headlight standards require that their design difficulties also. Here we use the free-form reflector design.

      The mold design of the headlight mask is based on the streamlined design of the mask, aesthetic requirements and light transmission characteristics. Using PartDesign, sketch the main model, then create the main model, add features, create other features, insert new features or bodies. In order to complete the three-dimensional mold design of the complex lamp mask.
