Problems solved by technology
However, when the injection nozzle of this structure injects raw materials, because the raw materials inevitably contain hard blocks or impurities, it is easy to block the spray cavity or nozzle, and the inside cannot be cleaned after the blockage, so the entire injection nozzle can only be replaced. The cost is high, or the original injection containing hard blocks or impurities into the injection mold will cause a great impact on the mold, and it is easy to damage the mold, which will further increase the cost of injection molding, and it will also require manpower and material resources to repair the mold
At the same time, when the existing injection nozzle is used to spray raw materials, the uneven mixing of the color masterbatch in the raw materials will easily lead to color difference on the surface of the processed parts, and the quality of the processed parts is difficult to be guaranteed.

The invention provides an injection molding nozzle. The nozzle comprises a connection part for connecting an injection molding machine, and a nozzle, wherein the injection molding nozzle further comprises a first spraying cavity part integrally formed with the connection part and a second spraying cavity part integrally formed with the nozzle; the first spraying cavity part and the second spraying cavity part are detachably connected; and a filter sheet is arranged between the first spraying cavity part and the second spraying cavity part and comprises at least one pair of openings with an intersectant central axis. Compared with the prior art, the invention has lower exchanging cost and better ensures the quality of the work-piece.
Description
technical field [0001] The invention relates to an injection molding nozzle, in particular to an injection molding nozzle used for injecting raw materials. Background technique [0002] Such as figure 1 As shown, the existing injection nozzle includes a connecting part 1 for connecting the injection molding machine, for screwing the connecting part 1 to the outer hex nut 2 of the injection molding machine, and connecting the connecting part 1 and the outer hexagon The nut 2 is formed in the integral spray chamber 3 and the nozzle 4 . However, when the injection nozzle of this structure injects raw materials, because the raw materials inevitably contain hard blocks or impurities, it is easy to block the spray cavity or nozzle, and the inside cannot be cleaned after the blockage, so the entire injection nozzle can only be replaced. The cost is high, or the injection of the original material containing hard blocks or impurities into the injection mold will cause a great impac...
