[0031] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Embodiment 1

[0033] See also Figure 1 - Figure 6 , a mixed double-color injection molding machine nozzle color mixing valve capable of producing striped patterns, comprising: a nozzle connecting seat 1, a first nozzle seat 2 being fixedly mounted on one end of the nozzle connecting seat 1, and a first injection cylinder 4 being fixedly mounted on the other end of the first nozzle seat 2;

[0034] A second nozzle seat 3 is provided below the first nozzle seat 2, and one end of the second nozzle seat 3 is fixedly connected to the nozzle connecting seat 1, a second glue injection cylinder 5 is fixedly installed on the other end of the second nozzle seat 3, and a nozzle 6 is fixedly installed on the end of the nozzle connecting seat 1 away from the second nozzle seat 3, and a front glue dispensing head 7, a small nozzle 8 and a glue dispensing rod 9 are respectively provided inside the nozzle 6, and the front glue dispensing head 7 is located between the small nozzle 8 and the glue dispensing rod 9;

[0035] The first ball sleeve 13 and the first ball 14 are arranged inside the glue dispensing rod 9;

[0036] The outer side wall of the glue dispensing rod 9 is provided with two second ball sleeves 15 and second balls 16 in a circular array.

[0037] The utility model provides a mixed double-color injection molding machine nozzle color mixing valve capable of producing striped patterns. When in use, the shot glue A enters from the second shot glue barrel 5, and enters the glue dispensing rod 9 and the front glue dispensing head 7 along the second nozzle seat 3 and the nozzle connecting seat 1. At the same time, the shot glue B enters from the first shot glue barrel 4, and enters the cavity between the glue dispensing rod 9, the front glue dispensing head 7 and the nozzle 6 along the first nozzle seat 2 and the nozzle connecting seat 1. Then, the shot glue A enters the small nozzle 8 through the front glue dispensing head 7, and then diffuses outwardly from the hole opened in the small nozzle 8 to the nozzle 6, so that the shot glue B surrounds the shot glue B to form a plurality of striped patterns, thereby achieving a striped effect. Finally, when the molten glue is sucked back, the first ball ferrule 13 and the second ball ferrule 15 respectively push the first ball 14 and the second ball 16 to block the inner and outer cavities of the glue dispensing rod 9, thereby preventing the occurrence of molten glue sucking back.

[0038] In addition, it should be noted that the two channels are independent of each other, so that mixed color injection can be achieved without impurities. Secondly, the number and size of the holes on the small nozzle 8 can be changed according to different product requirements. Finally, the stripe effect and shape of the stripes can be controlled by the injection pressure.
