Abstract

The invention discloses a color paste pump used for injecting liquid silica gel, which comprises a pump body, a color paste storage device, an air cylinder and a change-over valve, wherein the color paste storage device comprises a color paste cup spliced on the change-over valve; the pump body further comprises a piston rod provided with a seal ring; and the piston rod is connected with the output end of the air cylinder through a piston connector. The color paste pump used for injecting liquid silica gel is characterized in that the air cylinder is also connected with an oil cylinder; the air cavity of the air cylinder is connected with the oil cavity of the oil cylinder through oil pipes; and a hydraulic one-way throttle valve is arranged between the oil pipes. As the hydraulic one-way throttle valve is arranged between the oil pipes, and the piston connector is also connected with a measurement plate, the speed for hydraulic oil to flow into the air cavity of the air cylinder from the oil cavity of the oil cylinder can be controlled by controlling the flow of the one-way throttle valve, so that the upward-motion speed of the piston rod of the color paste pump can be controlled, and the color paste output speed can be controlled. A meter is used for measuring the displacement value of the piston rod motion, and the color paste output speed and the color paste output amount can be known by observing the variation of a meter value.

Description

technical field

[0001] The invention relates to a color paste pump, in particular to a color paste pump used for liquid silicone injection. Background technique

[0002] At present, the colorant pump is the equipment used to add color in the production of liquid silicone injection molding. In the past, the method of adding color was to directly mix the colorant into the raw material of liquid silicone, so that when we need to produce colored products, we can only use it When ordering raw materials, suppliers are required to mix colors into raw materials, which brings great inconvenience to our production. This color paste pump solves the problem of adding color to liquid silicone. Different colors can be added or replaced according to our requirements. The amount of color paste can be added according to the needs of the product. The replaceable and adjustable color paste pump is completely Solved the problem of adding color paste for liquid silicone injection molding. [0...
