A kind of flow pattern generation device and flow pattern generation method

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...

[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 is high, and the two materials will be mixed together when the screw is stirred, so that flow lines will not be produced. On the other hand, if the temperature is low, then The flow pattern color masterbatch is not well plasticized, which makes the flow pattern uneven and the effect is not good, and the cost of the flow pattern color masterbatch is high; the second is to use a two-color injection molding machine to produce raw materials of different colors in the two sets of material tubes. Then inject rubber into the mold through two sets of material tubes at the same time or at intervals, so as to achieve the effect of flow lines. The disadvantage of this method is that both sets of material tubes use screw-type material tubes, and only two colors of flow lines can be produced. The effect, the color is relatively monotonous, and the effect of the flow pattern is not good. On the other hand, the cost of the two-color injection molding machine is relatively high, and the function is relatively simple. Once the order for the flow pattern product is completed, it cannot be promoted on a large scale.
