Three-color liquid silicone injection molding device

Abstract

The invention aims at providing a three-color-liquid-silica-gel injection molding device. According to the three-color-liquid-silica-gel injection molding device, the multi-cavity individually driving method is adopted, and according to a gear changing box, single driving or two-shaft driving or three-shaft simultaneous driving of screws in three injection molding cavities is achieved, and three-cavity simultaneous injection molding or single-cavity injection molding or double-cavity injection molding is achieved. According to the three-color-liquid-silica-gel injection molding device, transmission gears of three screw pump screws are driven by a middle sliding gear, three pump shafts are independent, and each pump shaft is transmitted by a transmission shaft and a transmission gear. The three-color-liquid-silica-gel injection molding device is composed of a middle transmission spline shaft, a first-cavity transmission shaft, a first-cavity transmission gear limiting sleeve, a first-cavity transmission gear, a sliding gear shifting fork, a middle sliding gear, a second-cavity transmission gear, a third-cavity transmission gear, a middle sliding gear limiting sleeve, a first-cavity screw shaft, a connecting transition disc, a screw front-end bearing, a pump, a first-cavity screw, a control rod and the like. By means of the three-color-liquid-silica-gel injection molding device, the simultaneous injection molding problem of multi-color liquid gel can be solved, the structure is reliable, and using is convenient.

Description

technical field [0001] With the increasing number of silicone products, the requirements for silicone equipment are also getting higher and higher. Among them, the demand for injection molding equipment for multi-color integrated silicone products is becoming stronger and stronger. The invention relates to a three-color liquid silicone injection molding device. Background technique [0002] So far, silica gel is one of the materials with the best affinity for organisms. Therefore, there are more and more types of silicone medical and daily necessities. Previously, silicone products were mostly single-color, which limited the design and manufacture of silicone products in terms of types, logos, colors, etc. The key reason is that the silicone injection molding equipment is all single-material injection molding, even if there are multiple color requirements, the process of secondary injection molding has to be implemented. As a result, product quality declines and producti...

Problems solved by technology

Previously, silicone products were mostly single-color, which limited the design and manufacture of silicone products in terms of types, logos, colors, etc.

The key reason is that the silicone injection molding equipment is single-material injection molding. Even if there are multiple color requirements, the process of secondary injection molding has to be implemented.

As a result of the decline in product quality and the increase in production costs, it restricts the design and production of products
