Problems solved by technology

[0008] 1) The exhaust is not timely, there is a large amount of trapped gas in the cavity, which affects the molding filling, the adjustable range of the process is limited, the adjustment takes a long time, and the efficiency is low;
[0009] 2) Trapped gas remains between the cavity and the filling, causing the shape of the cavity to not be completely copied to the product, resulting in defects in product appearance and surface accuracy, and low product yield

Abstract

The invention discloses a die. The die comprises a first side profile, a second side profile and a fixed plate, wherein a cavity for containing a to-be-formed object is defined by the first side profile and the second side profile. At least one of the first side profile and the second side profile is provided with an exhaust duct communicated with the cavity. The fixed plate is provided with a channel for connecting the exhaust duct with a vacuumizing guide system.

Description

technical field [0001] The present application relates to mold structures in molding, and more particularly, the present application relates to molds with vent structures. Background technique [0002] In recent years, with the continuous deepening of networking and smart terminal applications, optical lenses, which are the core visual elements, are also constantly being introduced in the direction of high-resolution and miniaturization. Correspondingly, the lens manufacturing process, which is a key component of optical lenses, has also developed from the initial glass grinding to plasticizing processing methods such as compression molding and injection molding. With the increasing maturity of equipment, materials and mold manufacturing, lens molding applications will be more extensive. [0003] Fig. 1(a) and Fig. 1(b) schematically show a prior art mold 10 and the exhaust structure of the mold 10, respectively. [0004] As shown in FIG. 1( a ), the existing mold 10 mainl...
