Auto headlamps mould design Mar 09, 2018

The most demanding parts of the Auto exterior is the lamp.and therefore the mould design and manufacturing requirements are extremely high. The main components of the auto front and rear lamp are: left and right lenses, left and right decorative frame, left and right lamp housing, left and right mirrors and so on. Today's talk about the technology of the auto lamp lens mould.

Lateral core pulling mechanism is the most important core structure of the mould, the mould ingeniously adopted the "T-slot guide block + oblique inward slide block," the inner core-pulling mechanism successfully resolved the lateral transparent plastic parts on the surface of the plastic parts stay Under the traces of the problem.

The mould adopts ordinary pouring system, which is fed by the fan-shaped gate tower. Compared with the previous hot runner pouring system, the mould not only greatly reduces the cost, but also has better transmittance of the lens of the auto lamp.

The mould adopts the combined cooling system of "vertical cooling water pipe + inclined cooling water pipe + septa-type water well", the waterway is arranged along the cavity and the molding cycle is controlled within 35 seconds successfully, which effectively ensures the precision of the plastic part and the work of the mold productivity.

The plastic parts are pushed out by pushing blocks, which are not only stable but also leave no traces on the appearance.

Mould since the release, the movement is stable and smooth, plastic parts of the quality indicators have reached the design requirements, large, complex and long-life injection mold design a successful example.
