[0035] Reference below Figures 1 to 4 A dual material stack mold according to an embodiment of the present invention is described.

[0036] like Figures 1 to 4 As shown, the dual-material stacking mold according to an embodiment of the present invention includes a first mold body 100, a second mold body 200 and a rotary assembly 300, the first mold body 100 is provided with a first injection nozzle 101, the second mold body 200 is arranged opposite to the first mold body 100 and is provided with a second injection nozzle (not shown in the figure, blocked by the bracket 220), the rotary assembly 300 is arranged between the first mold body 100 and the second mold body 200, the rotary assembly 300 includes a support frame 310, a rotary mold module 320 rotatably arranged on the support frame 310 and a driving assembly 330 capable of driving the rotary mold module 320 to rotate, and both sides of the rotary mold module 320 are provided with a molding cavity 321;

[0037] The first mold body 100, the rotary assembly 300 and the second mold body 200 are sequentially distributed along a straight line. When the first mold body 100, the rotary assembly 300 and the second mold body 200 are molded together, a first mold cavity is formed between the first mold body 100 and one of the molding cavities 321 of the rotary assembly 300, and a second mold cavity is formed between the rotary mold module 320 and another molding cavity 321 of the rotary assembly 300. The first material is injected into the first mold cavity through the first injection nozzle 101 to form an injection molded semi-finished product. After the mold is opened, the driving assembly 330 drives the rotary mold module 320 to rotate 180°, and the injection molded semi-finished product rotates with the rotary mold module 320 to correspond to the second mold body 200. After the mold is closed again, the injection molded semi-finished product is located in the second mold cavity, and the second material is injected into the second mold cavity through the second injection nozzle, so that the second material and the first material are stacked to form an injection molded product.

[0038] By rotating the rotary mold module 320, the product can be driven to rotate to correspond to the second mold body 200 and close the mold for secondary injection molding, which reduces the process of manually transferring products to different processes in traditional production methods. The two molding cavities 321 of the rotary mold module 320 can respectively cooperate with the first mold body 100 and the second mold body 200 for synchronous cycle injection molding, thereby improving production efficiency, and there is no need to configure a turntable system, simplifying the mold structure and reducing costs.

[0039] Specifically, when used for the first time, when the first mold body 100, the rotary assembly 300 and the second mold body 200 are molded together, a first mold cavity is formed between the first mold body 100 and one of the molding cavities 321 of the rotary assembly 300, and a second mold cavity is formed between the rotary mold module 320 and another molding cavity 321 of the rotary assembly 300. The first material is injected into the first mold cavity through the first injection nozzle 101 to form an injection molded semi-finished product. No injection is performed on the second mold cavity. After the mold is opened, the driving assembly 330 drives the rotary mold module 320 to rotate 180°, and the injection molded semi-finished product rotates with the rotary mold module 320 to correspond to the second mold body 200. After the mold is closed again, the injection molded semi-finished product is located in the second mold cavity. In the mold cavity, the second material is injected into the second mold cavity through the second injection nozzle, so that the second material and the first material are stacked to form an injection molded product. At the same time, since the first injection nozzle 101 and the second injection nozzle are respectively arranged on the first mold body 100 and the second mold body 200, the first material and the second material can be injected without interfering with each other. At this time, the first material is injected into the first mold cavity through the first injection nozzle 101 to form an injection molded semi-finished product in the first mold cavity (that is, the first mold cavity and the second mold cavity are injected simultaneously). The mold is opened again, and the rotating mold module 320 is rotated 180°. This is repeated to continuously cycle the injection molding of dual-material products, which can greatly improve the injection molding production efficiency of dual-material products.

[0040] In addition, the two materials enter different mold cavities through two different flow channels, which are independent of each other, and can achieve different mold temperature control and optimize the product curing time.

[0041] In some embodiments of the present invention, the molding cavities 321 on both sides of the rotating mold module 320 have the same structure, and the first mold body 100 and the second mold body 200 are configured with different molding structures, so that the first mold cavity corresponds to the injection molded semi-finished product, and the second mold cavity corresponds to the injection molded finished product, which can satisfy the above-mentioned synchronous injection molding of the first mold cavity and the second mold cavity, and continuously inject and produce dual-material products.

[0042] like Figure 3 As shown, in some embodiments of the present invention, the support frame 310 is a frame structure, and the rotating mold module 320 can be rotatably arranged at the center of the support frame 310 of the frame structure, and the structural layout is stable and reliable.

[0043] Specifically, the driving component 330 is a motor driving mechanism, which can cooperate with a reducer to drive the rotating mold module 320 to rotate. Of course, in the specific implementation process, the driving component 330 can also be a rotating cylinder, etc., which will not be described in detail here.

[0044] In some embodiments of the present invention, the driving component 330 also includes a position sensor, which determines the rotation position of the rotating mold module 320. Since in the present invention, the rotating mold module 320 only needs to rotate 180°, the control is more convenient, with high control accuracy and reliability.

[0045] like Figure 1 As shown, in some embodiments of the present invention, the first mold body 100 is a fixed mold, the second mold body 200 is a movable mold, and the rotary assembly 300 can move between the first mold body 100 and the second mold body 200. By driving the second mold body 200, the mold closing action of the first mold body 100, the rotary assembly 300 and the second mold body 200 can be completed.

[0046] Specifically, when used, the first mold body 100 can be set on the fixed mold plate of the injection molding machine, and the first injection nozzle 101 is connected to the injection system of the injection molding machine. The second mold body 200 is set on the movable mold plate of the injection molding machine, and the mold is closed by the driving system of the injection molding machine. The rotary assembly 300 is set on the injection molding machine through a sliding mechanism and is located between the first mold body 100 and the second mold body 200. The opening and closing of the first mold body 100, the rotary assembly 300 and the second mold body 200 are completed by the mold closing and opening action of the injection molding machine.

[0047] like Figure 1 , Figure 4As shown, in some embodiments of the present invention, the second mold body 200 is provided with a bracket 220 for installing the second material injection mechanism 900, so that the second material injection mechanism 900 is arranged at the second mold body 200 to realize the injection of the second material at the second mold body 200.

[0048] Specifically, when used, the first mold body 100 can be set on the fixed mold plate of the injection molding machine, and the first injection nozzle 101 can be connected to the injection system of the injection molding machine, that is, the injection system of the injection molding machine is used to inject the first material. The second mold body 200 is set on the movable mold plate of the injection molding machine, and the second material injection mechanism 900 is set through the bracket 220 to realize the injection of glue into the second mold cavity, thereby completing dual-material injection molding.

[0049] Furthermore, by fixing the second material injection mechanism 900 on the upper side of the second mold body 200 , it is possible to inject material from the side of the second mold body 200 , and production space can also be saved.

[0050] In some embodiments of the present invention, the first material is plastic, and the second material is silicone. Of course, in the specific implementation process, the first material and the second material can also be other materials, which will not be described in detail here.

[0051] like Figure 4 As shown, in some embodiments of the present invention, the second mold body 200 is provided with a vacuum port 201, and the second mold cavity can be vacuumed through the vacuum port 201 to facilitate the suction of the second material such as silica gel.

[0052] In some embodiments of the present invention, a guide mechanism is provided between the first mold body 100 , the rotary assembly 300 and the second mold body 200 to improve the mold clamping accuracy of the first mold body 100 , the rotary assembly 300 and the second mold body 200 .

[0053] like Figures 1 to 4 In some embodiments of the present invention, the guide mechanism is a guide column group 110 disposed on the first mold body 100 and extending toward the rotation assembly 300 and the second mold body 200. The support frame 310 and the second mold body 200 are respectively provided with guide holes 111 corresponding to the guide column group 110. The cooperation between the guide column group 110 and the guide holes 111 improves the mold clamping accuracy.

[0054] It can be understood that in some embodiments of the present invention, the guiding mechanism can also be a slider and rail mechanism, such as setting a guide rail between the first mold body 100, the rotating assembly 300 and the second mold body 200, and setting sliders that cooperate with the guide rail on the first mold body 100, the rotating assembly 300 and the second mold body 200, respectively, which can also achieve the effect of improving the mold closing accuracy.

[0055] In some embodiments of the present invention, a first limiting structure capable of limiting the maximum distance between the first mold body 100 and the rotating assembly 300 is provided between the first mold body 100 and the rotating assembly 300 to control the mold opening distance and also enable the first mold body 100 and the rotating assembly 300 to be linked.

[0056] like Figures 2 to 4 In some embodiments of the present invention, the first limiting structure includes a first pull rod 120 and a first limiting hole 121 provided on the support frame 310 and capable of allowing the first pull rod 120 to pass through. A first limiting head 122 that cannot pass through the first limiting hole 121 is provided at one end of the first pull rod 120, and the other end of the first pull rod 120 passes through the first limiting hole 121 and is connected to the first mold body 100. Since the first limiting head 122 cannot pass through the first limiting hole 121, when the first mold body 100 and the rotary assembly 300 are separated to a set distance, the first limiting head 122 abuts against the opening of the first limiting hole 121, thereby limiting the further separation of the first mold body 100 and the rotary assembly 300, and at the same time, the first mold body 100 and the rotary assembly 300 can be linked.

[0057] In some embodiments of the present invention, a second limiting structure capable of limiting the maximum distance between the second mold body 200 and the rotating assembly 300 is provided between the second mold body 200 and the rotating assembly 300 to control the mold opening distance and also enable the second mold body 200 to be linked with the rotating assembly 300.

[0058] like Figures 2 to 4 In some embodiments of the present invention, the second limiting structure includes a second pull rod 210 and a second limiting hole 211 provided on the support frame 310 and capable of allowing the second pull rod 210 to pass through. One end of the second pull rod 210 is provided with a second limiting head 212 that cannot pass through the second limiting hole 211, and the other end of the second pull rod 210 passes through the second limiting hole 211 and is connected to the second mold body 200. Since the second limiting head 212 cannot pass through the second limiting hole 211, when the second mold body 200 and the rotary assembly 300 are separated to a set distance, the second limiting head 212 abuts against the opening of the second limiting hole 211, thereby limiting the further separation of the second mold body 200 and the rotary assembly 300, and at the same time, the second mold body 200 and the rotary assembly 300 can be linked.

[0059] In some embodiments of the present invention, the first mold body 100 is a fixed mold, the second mold body 200 is a movable mold, and the rotary assembly 300 can move between the first mold body 100 and the second mold body 200, that is, the second mold body 200 is configured with a driving mechanism. When the second mold body 200 moves, it can drive the first mold body 100 and the rotary assembly 300 to open the mold through the above-mentioned first limiting structure and the second limiting structure, and drive the second mold body 200 and the rotary assembly 300 to open the mold, thereby realizing the mold opening.

[0060] like Figure 1 , Figure 2 , Figure 4 In some embodiments of the present invention, a mold opening mechanism 400 is provided between the support frame 310 and the second mold body 200. The mold opening mechanism 400 can lock or unlock the rotating assembly 300 and the second mold body 200 to control the mold opening timing of the rotating assembly 300 and the second mold body 200.

[0061] Specifically, the mold opening latch mechanism 400 is a linkage or electrically controlled locking mechanism, which is a commonly used mechanism in the mold field. By setting the mold opening latch mechanism 400, when opening the mold, the rotary assembly 300 and the first mold body 100 are opened first. After the rotary assembly 300 and the first mold body 100 are opened to a set distance, the mold opening latch mechanism 400 is unlocked, and the rotary assembly 300 and the second mold body 200 are opened to achieve the set mold opening sequence.

[0062] It is understandable that, in some embodiments of the present invention, a mold opening mechanism may be provided between the support frame 310 and the first mold body 100 to achieve different mold opening sequences.

[0063] like Figures 2 to 4 In some embodiments of the present invention, the first mold body 100 and the second mold body 200 are respectively provided with positioning pieces 510, and the support frame 310 is provided with a locking mechanism 520 for inserting and locking the positioning piece 510. The first mold body 100, the second mold body 200 and the rotating assembly 300 can be locked through the locking mechanism 520, thereby improving the reliability during mold closing and having a certain guiding effect.

[0064] Specifically, the positioning member 510 is an outwardly convex structure, and the locking mechanism 520 is provided with a locking mechanism for the positioning member 510 to be inserted into and lock the positioning member 510 .

[0065] In some embodiments of the present invention, the rotary mold module 320 is detachably mounted to the support frame 310. In actual application, different rotary mold modules 320 can be replaced to meet the injection molding requirements of different products.

[0066] Specifically, the rotating mold module 320 can be made into a standard module and can be reused later, which can save a lot of material costs.

[0067] The injection molding system according to the second embodiment of the present invention comprises the dual-material stacking mold according to any one of the first embodiments of the present invention, and can improve the injection molding production efficiency of dual-material products.

[0068] Specifically, the injection molding system includes an injection molding machine, a first mold body 100 is arranged on a fixed mold plate of the injection molding machine, and a first injection nozzle 101 is connected to the injection system of the injection molding machine, a second mold body 200 is arranged on a movable mold plate of the injection molding machine, and the mold is closed by the driving system of the injection molding machine, a rotary assembly 300 is arranged on the injection molding machine through a sliding mechanism and is located between the first mold body 100 and the second mold body 200, and the opening and closing of the first mold body 100, the rotary assembly 300 and the second mold body 200 are completed by the mold closing and opening action of the injection molding machine, the injection system of the injection molding machine is used for the injection of the first material, and the second mold body 200 bracket 220 is provided with a second material injection mechanism 900 to realize the injection of glue into the second cavity, thereby completing the dual-material injection molding and improving the injection molding production efficiency of the dual-material product.

[0069] Of course, the invention is not limited to the above-mentioned embodiments, and those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
