Description

Mold turn nozzle mechanism

technical field

The utility model relates to the technical field of moulds, in particular to a mold turning nozzle mechanism applied in moulds.

Background technique

Mold is an indispensable and important equipment in injection molding. Injection molding is a method of injecting hot-melt plastic material into a closed molding space with the desired shape in the mold at high speed, and after the plastic material cools and solidifies, the mold is opened to eject the solidified plastic processed product to obtain a molded product. . Since the injection molding method has the characteristics of low molding cost, short molding cycle, simple molding process, and easy molding of plastic products with complex shapes, it is widely used in the field of plastic product manufacturing.

During product development, a product is usually assembled from many parts, and the plastic material or color of each part is different. Products with different raw materials or colors cannot be placed in the same set of molds during mold development. Such a product requires the development of many molds, which wastes a lot of cost.

Utility model content

In view of the above-mentioned shortcomings, the purpose of this utility model is to provide a mold nozzle mechanism with ingenious and reasonable structural design, which can close the runner channel of one of the product cavity and independently produce one of the products.

In order to achieve the above purpose, the technical solution provided by the utility model is: a mold turning nozzle mechanism, which includes a template, a turning nozzle insert and a positioning wave bead screw. The template is provided with at least two product cavities, two product cavities They are respectively connected to the main channel through the sub-runner. The nozzle insert is set at the junction of the main channel and the sub-runner, and can close one of the sub-runners when rotating. One end of the nozzle insert is provided with a wrench. position, and the other end face is provided with a positioning groove suitable for the positioning ball screw.

As an improvement of the present utility model, the peripheral part of an end surface of the nozzle insert is axially protruded to form an arc-shaped stop that can close the flow channel, and the wrench is located on one side of the nozzle insert. The center position of the end face.

As an improvement of the utility model, the profile of the cross section of the wrench is a regular hexagon.

As an improvement of the present utility model, the template is provided with a through hole matching the nozzle insert, and the other end of the nozzle insert is radially enlarged to form a limit portion, and The through hole is provided with a limiting slot adapted to the limiting part.

The beneficial effects of the utility model are: the utility model has an ingenious and reasonable structure, and multiple product cavities are arranged on the same template. The arc-shaped stopper on the other side closes the runner channel of the product cavity that does not need to be produced on the other side, and the positioning is realized by the cooperation of the positioning ball screw and the positioning groove, so that any product can be produced independently to meet diversified production In addition, the overall structure is simple and compact, and multiple products of different materials or colors can be produced in the same set of molds. The cost is low, and it is easy to realize, which is conducive to widespread application.

Below in conjunction with accompanying drawing and embodiment, the utility model is further described.

Description of drawings

Fig. 1 is a front structural schematic view of the utility model.

Fig. 2 is a side view structural diagram of the utility model.

Detailed ways

Referring to Fig. 1 and Fig. 2, a mold nozzle mechanism provided in this embodiment includes a template 1, a nozzle insert 2 and a positioning ball screw 3, and the template 1 is provided with at least two product cavities 11, and two product cavities. The cavity 11 communicates with the main channel through the runners 12 respectively, and the nozzle insert 2 is arranged at the junction of the main channel and the runners 12, and can close one of the runners 12 when rotating. One end surface of 2 is provided with a wrench position 21, and the other end surface is provided with a positioning groove 22 adapted to the positioning ball screw 3. After the nozzle insert 2 is rotated in place, the positioning ball screw 3 just presses against the positioning groove 22, and the stability is good.

The template 1 is provided with a through hole matching the nozzle insert 2, and the other end of the nozzle insert 2 is radially enlarged to form a stopper, and the through hole is provided with A limit slot matching the limit part.

Specifically, the peripheral portion of an end surface of the nozzle insert 2 protrudes axially to form an arc-shaped stop 23 capable of closing the flow channel 12 , and the wrench position 21 is located on an end surface of the nozzle insert 2 central location. Preferably, the profile of the cross section of the wrench position 21 is a regular hexagon, which brings convenience to the operation.

When it is necessary to produce products of different materials or colors, it is only necessary to turn the nozzle insert 2 so that the arc-shaped stopper 23 on the other side closes the runner 12 of the product cavity 11 that does not need to be produced on the other side, and passes through The positioning ball screw 3 cooperates with the positioning groove 22 to realize positioning, and the working stability is good, so that any product can be produced independently to meet diversified production needs.

According to the disclosure and teaching of the above specification, those skilled in the art to which the present utility model belongs can also change and modify the above embodiment. Therefore, the utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the present utility model. As described in the above embodiments of the present utility model, mechanisms of other structures obtained by adopting the same or similar structures are all within the protection scope of the present utility model.
