Description

A multi-head straight pouring hot nozzle

technical field

The utility model relates to the field of injection molds, in particular to a multi-head straight pouring nozzle.

Background technique

Injection molding process is a molding process that is often used in industrial production at present. In the injection molding process, raw materials need to be injected into the mold through the hot runner hot nozzle, so the injection molding hot nozzle is a very important part. Conventional and traditional hot runners are It is a one-to-one glue-feeding product. For molds with relatively close product positions, sometimes the mold space is small, the glue causes insufficient space for the nozzle position, and the position of the hot nozzle interferes.

Contents of the invention

The technical problem to be solved by the utility model is to provide a multi-head straight pouring hot nozzle, which has several hot nozzle flow channels and corresponding hot glue ports, which can realize the injection molding of multiple small products by a single hot nozzle, which is different from the traditional Compared with the hot nozzle, on the one hand, it greatly reduces the production cost and improves the production efficiency. At the same time, it also makes the cavity of the mold more closely arranged and reduces the volume of the mold.

The technical scheme adopted by the utility model to solve the technical problem is: provide a multi-head straight pouring hot nozzle, including a hot nozzle body and a sleeve, one end of the hot nozzle body is the discharge end, and the other end is the feed The middle part of the hot nozzle body is a hot runner, and a sleeve is sleeved on the outside of the hot nozzle body. A cavity partition arranged around the hot runner is formed between the sleeve and the hot nozzle body. The cavity partition A heater is installed in the layer, and one end of the hot nozzle body is inserted and fixed with an injection part, and one end of the inner hole of the injection part communicates with the hot runner, and the other end has several inclined discharge holes. The outer end surface of the injection part is centered with a regular hexagonal groove. The bottom of the regular hexagonal groove is arc-shaped and extends to each top corner. The discharge inclined hole is arranged on the corresponding top of the regular hexagonal groove. corner.

As a supplement of the present utility model, the feed end of the hot nozzle body is arranged with an annular platform, the side wall of the annular platform axially protrudes from the annular stopper in the direction of the discharge end, and the sleeve's One end is inserted into the gap between the annular limiting part and the nozzle body.

As another supplement of the present invention, the said annular limiting portion is radially pierced with a power connection wire connected to the heater.

Further, a retaining ring is centrally installed on the feed end surface of the hot nozzle body.

The utility model has a simple structure, has several hot nozzle runners and corresponding hot glue ports, and can realize the injection molding of multiple small products by a single hot nozzle. Compared with the traditional hot nozzle, on the one hand, the production is greatly reduced The cost is improved, and the production efficiency is improved. At the same time, the cavity of the mold is arranged more closely, and the volume of the mold is reduced.

Detailed ways

Below in conjunction with specific embodiment, further set forth the utility model. It should be understood that these embodiments are only used to illustrate the present utility model and are not intended to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by the appended claims of the application.

As shown in Figure 1-2, the embodiment of the present invention relates to a multi-head straight pouring hot nozzle, including a hot nozzle body 1 and a sleeve 3, one end of the hot nozzle body 1 is the discharge end, and the other end It is the feed end, the middle part of the hot nozzle body 1 is the hot runner 2, the outer side of the hot nozzle body 1 is sleeved with a sleeve 3, and the sleeve 3 and the hot nozzle body 1 are arranged around the hot runner 2 The cavity interlayer 4, the heater 5 is installed in the cavity interlayer 4, one end of the hot nozzle body 1 is inserted and fixed with the injection part 6, and one end of the inner hole 8 of the injection part 6 is connected with the heat flow The channel 2 communicates with each other, and the other end has a number of discharge inclined holes 7. The outer end surface of the injection part 6 is centered with a regular hexagonal groove 13. The bottom of the regular hexagonal groove 13 is arc-shaped and extends to every vertex, the discharge inclined hole 7 is arranged at the corresponding vertex on the regular hexagonal groove 13.

The feed end of the hot nozzle body 1 is provided with an annular platform 11, the side wall of the annular platform 11 axially protrudes from the annular stopper 10 toward the discharge end, and one end of the sleeve 3 is embedded in the annular In the gap between the limiting part 10 and the nozzle body 1 .

A power connection wire 9 connected to the heater 5 is threaded radially through the annular limiting portion 10 .

A retaining ring 12 is centrally installed on the feed end surface of the hot nozzle body 1 .

Example

Insert the hot nozzle into the mold cavity of the mold, and each discharge inclined hole 7 faces the mold cavity of different small products. When in use, the heater 5 is energized to heat the hot nozzle body 1, and at the same time, from the hot nozzle body 1 The material is injected at the feed end, the raw material is in a flowing state at high temperature, and flows along the hot runner 2 to the discharge end of the hot nozzle body 1, and the raw material flows out from each discharge inclined hole 7 and enters the cavity of each small product , each vertex of the regular hexagonal groove 13 corresponds to a small product cavity, which can play a guiding role for the raw materials flowing out of the inclined discharge hole 7 .

The utility model has a simple structure, has several hot nozzle runners and corresponding hot glue ports, and can realize the injection molding of multiple small products by a single hot nozzle. Compared with the traditional hot nozzle, on the one hand, the production is greatly reduced The cost is improved, the production efficiency is improved, and at the same time, the cavity of the mold is arranged more closely, and the volume of the mold is reduced.
