Abstract

The invention provides a flow liner generating device. The device comprises a base, a plunger cylinder and a hopper. The plunger cylinder is hollow to form a plunger compartment; the hopper is communicated with the plunger compartment; a plunger rod is movably arranged in the plunger compartment; the base is provided with a color mixer and a shunt network; the color mixer comprises a first interface, a second interface and a third interface; the first interface is connected with an injection molding machine; the second interface is communicated with the plunger compartment of the plunger cylinder; the third interface is communicated with the shunt network; and a nozzle is arranged outside the shunt network. Pigments in different color are respectively fully mixed with the main ingredient in the color mix, and segmented by the shunt network into multiple color strips with uniform color distribution; then injection molding is conducted. The injection molding product has the advantages of bright uniform color, good flow liner effect, simple structure, no requirement of individual customization and low cost.

Description

technical field

[0001] The invention relates to an injection molding machine, in particular to an injection molding machine capable of producing flow lines and a method for generating flow lines. Background technique

[0002] Existing injection molding machines usually use two methods to achieve the effect of color mixing and flow lines on the product: the first is to add flow line color masterbatch to the main material, and use the flow line color masterbatch and the plasticizing temperature of the main material Poor, so that the flow pattern color masterbatch is slowly released in the main material, resulting in flow lines, this method can be produced in ordinary injection molding machines, but the disadvantage is that different raw materials will have different molding temperatures, so it is difficult to control The degree of plasticization of the flow pattern color masterbatch, the color masterbatch will melt with the main material at the same time when the temperature i...
