Abstract

The invention provides a mold pressing mechanism for an aspheric lens, wherein the mechanism comprises a workbench, a lower die mechanism, and an upper die mechanism; the workbench is provided with athrough hole for the telescoping of a lifting arm; the lower die mechanism is arranged on the workbench, the lifting arm is arranged below the lower die mechanism, and the lower die mechanism is driven by a driving mechanism to ascend and descend; the lower die mechanism is sequentially provided with a first fixing plate, a lower heat insulation plate, a second fixing plate and a lower die plate from bottom to top, the second fixing plate and the lower die plate are detachably fixed, and the lower die plate is made of a tungsten steel material; the upper die mechanism is arranged over the lower die mechanism and fixed to the top plate, the lower die mechanism is sequentially provided with a first upper fixing plate, an upper heat insulation plate, a second upper fixing plate and an upper die plate from top to bottom, the second upper fixing plate and the upper die plate are detachably fixed, a die cavity and a T-shaped exhaust channel are formed in the upper die plate, and the exhaustchannel communicates with the die cavity. The mold pressing mechanism has the characteristic of good production effect.

Description

technical field [0001] The invention belongs to the technical field of moulds, and relates to a molding mechanism for an aspheric lens. Background technique [0002] Aspherical lenses are widely used in car lighting. The projection lighting system commonly used in car lights generally includes light sources, reflectors, visors and lenses. The reflector is ellipsoidal, the luminous center of the light source is set at the near focal point of the ellipsoidal reflector, and the light emitted by the light source converges near the far focus of the ellipsoidal reflector after being reflected by the ellipsoidal reflector. [0003] The process flow of aspheric lens preparation is as follows: 1. Cut a certain length of wire rod material into block raw materials of specified size; 2. After being softened at high temperature in a rotary furnace, it will be molded, passed through a cooling box, and then cooled and shaped. Get an aspheric lens. [0004] The existing aspherical lens mo...
