Description

A four-head hot nozzle for injection molding

technical field

The utility model relates to the field of injection molds, in particular to a four-head hot nozzle for injection molding.

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 four-head hot nozzle for injection molding, 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 four-head hot nozzle for injection molding, including a hot nozzle body and a tablet, one end of the hot nozzle body is a discharge end, and the other end is a feed The middle part of the hot nozzle body is a hot runner, and a cavity partition is arranged around the hot runner inside the hot nozzle body. A heater is installed in the cavity partition. The feed material of the hot nozzle body A pressing piece is installed at the end of the cavity to block one end of the cavity compartment. The discharge end of the hot nozzle body has four discharge inclined holes evenly arranged around the center line of the hot nozzle body. The discharge inclined holes Connected with the hot runner, the discharge end of the hot nozzle body is axially protruded and arranged with several conical guide heads, and the conical guide heads are adjacent to the corresponding inclined discharge holes.

As a supplement of the present invention, the body of the hot nozzle between the cavity interlayer and the hot runner is a hot nozzle core, and the pressing piece is sleeved on the outside of the hot nozzle core, and the end surface of the pressing piece is in contact with the hot nozzle core. The end faces of the nozzle core are connected and fixed by retaining rings, which have a simple structure and are easy to assemble.

As another supplement of the present invention, the position of the hot nozzle body close to the pressure sheet is radially pierced with a power connection line connected with the heater.

The utility model has several hot nozzle runners and corresponding hot glue ports, which can realize the injection molding of multiple small products by a single hot nozzle. Compared with the traditional hot nozzle, on the one hand, it greatly reduces the production cost and improves the 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.

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 utility model relates to a four-head hot nozzle for injection molding, including a hot nozzle body 1 and a pressing sheet 2, 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 a hot runner 3, and the inside of the hot nozzle body 1 is arranged with a cavity partition 4 around the hot runner 3, and a heater 5 is installed in the cavity partition 4 , the feed end of the hot nozzle body 1 is equipped with a pressing sheet 2 to block one end of the cavity interlayer 4, and the discharge end of the hot nozzle body 1 has four holes surrounding the hot nozzle body 1. The outlet inclined hole 6 evenly arranged on the center line, the outlet inclined hole 6 communicates with the hot runner 3, and the outlet end of the hot nozzle body 1 is axially protruded and arranged with several conical guide heads 7, the conical guide head 7 leans against the corresponding discharge inclined hole 6.

The hot nozzle body 1 between the cavity interlayer 4 and the hot runner 3 is a hot nozzle core 10, and the pressure piece 2 is sleeved on the outside of the hot nozzle core 10, and the end surface of the pressure piece 2 is in contact with the hot nozzle core. The end faces of 10 are connected and fixed by retaining ring 8, which is simple in structure and easy to assemble.

A power connection wire 9 connected to the heater 5 is radially threaded on the nozzle body 1 near the pressing piece 2 .

Example

Insert the hot nozzle into the mold cavity of the mold, and each discharge inclined hole 6 faces the mold cavity of different small products. When in use, the heater 5 is energized to heat the hot nozzle core 10, and at the same time, from the hot nozzle core 10 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 3 to the discharge end of the hot nozzle body 1, and the raw material flows out from each discharge inclined hole 6 and enters the cavity of each small product , The conical guide head 7 can play a guiding role for the raw material flowing out of the inclined discharge hole 6 .

The utility model has several hot nozzle runners and corresponding hot glue ports, which can realize the injection molding of multiple small products by a single hot nozzle. Compared with the traditional hot nozzle, on the one hand, it greatly reduces the production cost and improves the 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.
