A precise liquid silicone injection machine and its production line for silicone products

Abstract

The invention relates to a precise liquid silica gel injection machine and a silica gel product production line thereof. The precise liquid silica gel injection machine comprises a machine frame, a control electricity box, a lifting device, an A silica gel pumping device, a B silica gel pumping device, a color paste pumping device and a plurality of hollow rubber pipes; the control electricity box is installed in front of the machine frame; two silica gel storage buckets loaded with A silica gel and B silica gel are placed on the machine frame; the lifting device drives the A silica gel pumping device and the B silica gel pumping device to stretch into the silica gel storage buckets to pump the silica gel; and the color paste pumping device pumps color paste independently. The precise liquid silica gel injection machine further comprises a three-liquid quantitative injection device; the A silica gel pumping device, the B silica gel pumping device and the color paste pumping device convey the A silica gel, the B silica gel and the color paste to the three-liquid quantitative injection device through the rubber pipes, and the three-liquid quantitative injection device precisely controls the mixing ratio of the A silica gel, the B silica gel and the color paste, so that high-purity liquid silica gel is obtained and directly and quantitatively injected into a mold cavity of a flat plate machine through the rubber pipes.

Description

technical field [0001] The invention relates to the field of liquid silica gel injection machines, in particular to a precise liquid silica gel injection machine and a production line for silica gel products. Background technique [0002] In the silicone molding industry, according to the form of silica gel, silica gel is divided into liquid silica gel and solid silica gel. Liquid silica gel has excellent transparency, tear resistance, good resilience, antibacterial denaturation, thermal stability, and aging resistance. And weather resistance, and no harmful substances after vulcanization, so liquid silica gel gradually replaces solid silica gel as the main raw material for injection molding. The traditional process of using a flat vulcanizing machine to produce solid silica gel products requires 4-6 workers for the processes of mixing, cutting, weighing, feeding (starting up), taking products, and removing flash. [0003] The shortcoming of above-mentioned method is: many ...
