Description

Multiple birth molding system

This creation relates to an injection molding die, and more particularly to a multi-mold system.

Injection molding is a manufacturing process that uses an injection molding machine to inject molten material into a mold to produce a product. In conventional injection molding, one injection molding machine corresponds to one set of molds for production. When the production demand is high and two or more sets of replica molds are available, a corresponding number of injection molding machines are required, resulting in the occupation of more equipment resources. In this case, if there is insufficient backup of injection molding machines, it may be unable to fully meet all process requirements and may even affect other ongoing process operations.

Therefore, the purpose of this invention is to provide a multiple birth molding system to solve the problems of prior art.

The technical means employed in this invention to solve the problems of prior art is to provide a multi-mold system, comprising: a plurality of mold bodies; and a hot runner fixing plate having an injection molding machine connection surface and a mold fixing surface. The hot runner fixing plate is disposed on the plurality of mold bodies such that the plurality of mold bodies are fixed together to the mold fixing surface. The hot runner fixing plate is provided with a main nozzle, a plurality of hot nozzles, and a hot runner... The system includes a main sprue located on the injection molding machine connection surface for connection to an injection molding machine, a plurality of hot runners located on the mold fixing surface and respectively connected to a plurality of mold bodies, and a hot runner structure located within the hot runner fixing plate, which branches the main sprue to the plurality of hot runners, allowing the injection molding machine to simultaneously inject the plurality of mold bodies through the main sprue, the hot runner structure, and the plurality of hot runners in sequence.

In one embodiment of the invention, a multiple mold system is provided, wherein a plurality of the mold bodies have a total of two or more different cavity structures.

In one embodiment of the invention, a multiple-mold system is provided, wherein a plurality of the mold bodies have a total of two or more different external dimensions.

In one embodiment of the invention, a multiple-mold system is provided, wherein a plurality of the mold bodies are arranged in a parallel and adjacent manner in the same direction.

In one embodiment of the invention, a multi-mold system is provided, wherein a plurality of mold bodies are multi-material injection mold bodies, the hot runner retainer plate has a plurality of main nozzles corresponding to the amount of material type injected in the multi-material injection, each mold body is correspondingly connected to a plurality of hot nozzles corresponding to the amount of material type injected in the multi-material injection, and the hot runner structure is configured to divert each of the main nozzles to the plurality of hot nozzles corresponding to the material type, so as to simultaneously inject the plurality of mold bodies in a multi-material injection manner.

In one embodiment of this invention, a multiple mold system is provided, further comprising: a plurality of ejection mechanisms, each correspondingly disposed on a plurality of mold bodies; and an ejection mechanism linkage plate, disposed between the plurality of ejection mechanisms and an ejection drive mechanism in a manner that is linked together with the plurality of ejection mechanisms, so that the ejection drive mechanism can simultaneously push the plurality of ejection mechanisms via the ejection mechanism linkage plate, thereby simultaneously ejecting the plurality of mold bodies.

In one embodiment of the invention, a multiple mold system is provided, wherein the ejection mechanism is a pin ejection mechanism.

Through the technical means employed in this invention, the multi-mold system can utilize hot runner technology to transform one nozzle of an injection molding machine into multiple nozzles via a hot runner fixing plate. This allows for the combined production of two or more identical molds, or the simultaneous injection molding of the same material from two or more different molds. Consequently, this multi-mold system effectively reduces the resource requirements of the injection molding machine, thereby maintaining or increasing production capacity.

The following description, based on Figures 1 through 5, illustrates the embodiments of the invention. This description is not intended to limit the embodiments of the invention, but rather to provide one example of its implementation.

As shown in Figures 1 to 4, a multiple-mold system 100 according to an embodiment of the present invention includes: a plurality of mold bodies 1; and a hot runner fixing plate 2, having an injection molding machine connection surface and a mold fixing surface. The hot runner fixing plate 2 is disposed on the plurality of mold bodies 1 such that the plurality of mold bodies 1 are fixed together to the mold fixing surface. The hot runner fixing plate 2 is provided with a main nozzle 21, a plurality of hot nozzles 22, and a hot runner structure 23. The main nozzle 21 is located... On the injection molding machine connection surface, for connection of an injection molding machine (not shown), a plurality of hot sprue nozzles 22 are located on the mold fixing surface and are respectively connected to a plurality of mold bodies 1. The hot runner structure 23 is located in the hot runner fixing plate 2 and branches the main nozzle 21 to the plurality of hot sprue nozzles 22, so that the injection molding machine can simultaneously perform injection molding on the plurality of mold bodies 1 through the main nozzle 21, the hot runner structure 23, and the plurality of hot sprue nozzles 22 in sequence (as shown in Figure 4).

Preferably, as shown in Figures 1 to 4, in the multiple mold system 100 of this invention, a plurality of the mold bodies 1 have a total of two or more different cavity structures. That is to say, the multiple mold system 100 of this invention is not limited to the combined production of two or more sets of the same molds. Even molds used to produce products of different shapes can be applied to the multiple mold system 100 of this invention and injection molded simultaneously, thereby forming and manufacturing them together.

Preferably, as shown in Figures 1 to 4, in the multiple mold system 100 of this invention, a plurality of the mold bodies 1 have a total of two or more different external dimensions. That is to say, the multiple mold system 100 of this invention is not limited to the combined production of two or more sets of molds with the same external dimensions. Even if the external dimensions are different, as long as the products are made of the same material, they can be applied to the multiple mold system 100 of this invention and injection molded at the same time, thereby forming and manufacturing them together.

Additionally, it should be noted that although this embodiment uses two sets of the mold body 1 as an example, the invention is not limited to this. In addition to being applied to two mold bodies 1, the multiple birth mold system 100 of the invention can also be applied to three or more mold bodies 1, thus being a multiple birth mold system 100 for twins, triplets or more.

Preferably, as shown in Figures 1 to 4, in the multiple mold system 100 of this embodiment, a plurality of the mold bodies 1 are arranged in a parallel and adjacent manner in the same direction. Specifically, with this arrangement, the hot runner fixing plate 2, the main nozzle 21, the plurality of hot nozzles 22, and the hot runner structure 23 therein can be simplified to a simpler configuration as in this embodiment, thus effectively reducing component manufacturing costs and system assembly difficulty. Of course, this invention is not limited to this, and the plurality of mold bodies 1 can also be arranged in other ways according to different needs.

Preferably, in other embodiments not shown in the figures, the plurality of mold bodies 1 can be multi-material injection mold bodies, the hot runner fixing plate 2 has a plurality of main nozzles 21 corresponding to the amount of material types injected in the multi-material injection, each mold body 1 is correspondingly connected to a plurality of hot nozzles 22 corresponding to the amount of material types injected in the multi-material injection, and the hot runner structure 23 is configured to divert the flow from each of the main nozzles 21 to the plurality of hot nozzles 22 corresponding to the material types, so as to simultaneously perform injection molding on the plurality of mold bodies 1 in a multi-material injection manner. That is to say, the multi-mold system 100 of this invention can also be applied to two-color, three-color, two-material, three-material and other multi-material injection molding, and simultaneously produce multiple products with two or more different colors and/or materials.

Preferably, as shown in Figures 1 to 5, the multiple mold system 100 of the present invention further includes: a plurality of ejection mechanisms 3, respectively disposed on a plurality of mold bodies 1; and an ejection mechanism linkage plate 4, disposed between the plurality of ejection mechanisms 3 and an ejection drive mechanism (not shown) in a manner that is linked with the plurality of ejection mechanisms 3, so that the ejection drive mechanism can push the plurality of ejection mechanisms 3 together via the ejection mechanism linkage plate 4, thereby simultaneously ejecting the plurality of mold bodies 1 (as shown in Figure 5).

In this embodiment, the plurality of ejector mechanisms 3 are preferably the plurality of existing ejector mechanisms of the mold body 1. By means of the ejector mechanism linkage plate 4, the ejector drive mechanism equipped with the injection molding machine can simultaneously drive the plurality of ejector mechanisms 3 via the ejector mechanism linkage plate 4. In this way, not only can one injection molding machine be used to perform injection molding on multiple sets of molds at the same time during injection molding, but the same ejector drive mechanism equipped with the same injection molding machine can also be used to eject products from multiple sets of molds at the same time during ejection, thereby effectively reducing the occupation of equipment resources of the injection molding machine.

Preferably, as shown in Figures 3 to 5, in the multiple mold system 100 of this embodiment, the ejector mechanism 3 is a pin-type ejector mechanism. Of course, this embodiment is not limited to this, and the ejector mechanism 3 may also be other types of ejector mechanisms.

With the above structure, the present invention's multi-mold system 100 can utilize hot runner technology to generate multiple nozzles from a single injection nozzle of an injection molding machine via a hot runner fixing plate, thereby enabling the combined production of two or more identical molds, or the simultaneous injection molding of the same material from two or more different molds. In this way, the present invention's multi-mold system 100 can effectively reduce the equipment resource requirements of the injection molding machine, thereby maintaining or increasing production capacity.

The above description and explanation are merely illustrative examples of the preferred embodiments of this invention. Those skilled in the art may make other modifications based on the scope of the patent application as defined below and the above explanation, but such modifications shall still be within the spirit of the invention and the scope of the claims of this invention.
