Description
Technical Field
The utility model relates to a mouth is irritated to the injection molding machine, especially relates to a cooling structure that mouth was irritated to injection molding machine.
Background
The nozzle is a mould fitting for injecting molten plastic material from a nozzle of an injection moulding machine into a runner component inside a mould, a product is formed in the injection moulding mould, and the temperature of plastic melt can be accurately controlled in a runner system. The plastic can flow into each die cavity in a more uniform and consistent state, so that the quality of the produced product is consistent. Controlling the temperature of the mold around the nozzle is critical to improving the quality of the product. Poor cooling around the filling nozzle can cause silver streaks, bubbles, pores and black spots on the appearance of the product, and the color and luster of the product are inconsistent; the material cake is difficult to separate and has the problem of wire drawing.

Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described with reference to fig. 1 and the specific embodiments.
As shown in the attached drawing 1, the cooling structure of the nozzle of the injection molding machine comprises a nozzle 1, a pressing plate 2 and an insert 3, wherein the pressing plate 2 is arranged on the upper portion of the insert 3, the nozzle 1 is arranged in the middle of the pressing plate 2, a water inlet 4 and a water outlet 5 are formed in the pressing plate 2, a cooling water channel 6 is arranged around the nozzle 1, and the cooling water channel 6 is respectively connected with the water inlet 4 and the water outlet 5 through pipelines.
Further, a sealing ring 7 is arranged at the upper part of the cooling water channel 6.
Furthermore, a cooling water channel 6 is arranged on the joint surface of the pressing plate 2 and the insert 3, a water inlet 4 is connected with an inlet of the cooling water channel 6 through a vertically downward pipeline, and an outlet of the cooling water channel 6 is connected with a water outlet 5 through a vertically upward pipeline.
Further, the cooling water channel 6 is provided as an annular water channel structure.
The utility model discloses a theory of operation and working process as follows: the insert is a part formed by a molten plastic material, the product is formed in an injection mold, the mold temperature of each part is ensured to be consistent, the pressing plate plays a role of fixing and supporting the insert, the water path is increased, the mold temperature can be effectively controlled, the cooling time is shortened, the production efficiency is improved, and the injection molding cost is reduced; the cooling water path of the filling nozzle is close to the filling nozzle by an annular water guide groove structure, a sealing ring is additionally arranged, cooling water enters through a water inlet, flows through the pressing plate and the insert through the annular water path and flows out through a water outlet of the pressing plate to form circulating water transportation and high-efficiency heat dissipation, and acts on the periphery of the filling nozzle to rapidly cool thermoplastic in the filling nozzle, so that the effect of shortening the die opening time and accelerating the production efficiency is achieved; meanwhile, the structure is simple, the occupied space is small, and the cost can be effectively saved.
Utilize technical scheme, or technical personnel in the field are in the utility model discloses under technical scheme's the inspiration, design similar technical scheme, and reach above-mentioned technological effect, all fall into the utility model discloses a protection scope.
