Problems solved by technology

[0002] At present, in the pouring process of resin lens production, due to the different viscosities of the raw materials of different lenses and the different sizes of the molds, it is difficult to control the flow rate of the lens material liquid, and it is troublesome to switch between molds. If the air enters the air, it is necessary to re-exhaust the air bubbles. However, the existing filter device does not have a special air-exhaust device in the pipeline of the pouring material, which is very troublesome, and it will not be able to achieve continuous discharge.
The above problems will lead to the inability to continue the pouring process, affecting production efficiency and product quality

Abstract

The invention discloses a lens continuous pouring system and a pouring process thereof. The system comprises a material tank, a filtering device capable of easily discharging bubbles, a material pouring valve and a material pouring needle head which are sequentially connected through a material pouring pipeline. The pouring needle head is fixed on a pouring frame on a pouring table; a template push disc with a plurality of empty grids is placed on the pouring table at a lower end of the pouring needle head, a feeding port, an exhaust valve and a pressure control assembly are arranged at the top of the material tank, a discharging valve is arranged at a bottom of the material tank, one end of the pressure control assembly is connected with a vacuum generation device, and the other end is connected with a compressed air device. A stirrer is mounted in the material tank. By means of the system and process, lens feed liquid can be effectively and continuously poured, the production efficiency is improved, and the product quality is improved.

Description

technical field [0001] The invention belongs to the field of resin lenses, and in particular relates to a continuous casting system for lenses and a technology thereof. Background technique [0002] At present, in the pouring process of resin lens production, due to the different viscosities of the raw materials of different lenses and the different sizes of the molds, it is difficult to control the flow rate of the lens material liquid, and it is troublesome to switch between molds. If the air enters the filter, it is necessary to re-discharge the air bubbles. However, it is very troublesome that there is no special air-exhaust device in the pipeline of the existing filter device for air-exhaust pouring material, which will not be able to achieve continuous discharge. The above-mentioned problems will cause the pouring process to not be carried out continuously, affecting production efficiency and product quality. Contents of the invention [0003] The purpose of the pre...
