[0030] Injection molding is a method of producing industrial products. Products usually use rubber injection molding and plastic injection molding. The injection mold is a tool for producing plastic products and also a tool for giving plastic products a complete structure and precise dimensions. Injection molding is a processing method used in mass production of certain parts with complex shapes. Specifically, it refers to the injection of heated and melted plastic into the mold cavity by the injection molding machine under high pressure, and after cooling and solidification, a molded product is obtained.

[0031] A large number of inserts are arranged in the internal space of the mold to form the shape of the product. After the product is injection molded in the mold, the product fills the remaining pores in the internal space of the mold, resulting in insufficient space for the product to be stably separated from the mold during the process of the product being separated from the mold. Therefore, the product structure is easily deformed or even damaged during the process of the product being separated from the mold, thus affecting its use.

[0032] Based on this, an embodiment of the present application provides an injection mold, which drives the first insert assembly, the second insert assembly and the third insert assembly to separate in sequence through a driving device after the product is injection molded, so that there is sufficient space for the product to separate from the mold and prevent the product from being deformed.

[0033] The injection mold will be described below in conjunction with the accompanying drawings.

[0034] Reference Figure 1 and Figure 2 As shown, Figure 1 A cross-sectional view of an injection mold provided in one embodiment of the present application, Figure 2 The cross-sectional view of a cavity 300 provided by an embodiment of the present application, the embodiment of the present application provides an injection mold, comprising: an upper mold plate 100, comprising an upper mold core 110, the upper mold core 110 is arranged at the bottom of the upper mold plate 100; a lower mold plate 200, comprising a lower mold core 210, the lower mold core 210 is arranged at the top of the lower mold plate 200, the upper mold core 110 and the lower mold core 210 abut against each other to form a receiving space; a cavity 300, penetrating the upper mold core 110 and the lower mold core 210 to be arranged in the receiving space In the meantime, the cavity 300 is used for product injection molding. The cavity 300 includes a nozzle 340, a first insert assembly 310, a second insert assembly 320 and a third insert assembly 330. The first insert assembly 310 is arranged on the nozzle 340, the second insert assembly 320 is arranged around the first insert assembly 310, and the third insert assembly 330 is arranged around the second insert assembly 320; the driving mechanism is used to drive the first insert assembly 310, the second insert assembly 320 and the third insert assembly 330 to be demolded in sequence.

[0035] It should be noted that the upper mold core 110 is fixed to the bottom of the upper mold plate 100, and the lower mold core 210 is fixed to the top of the lower mold plate 200, and can be fixed and installed by bolts respectively. The upper mold core 110 and the lower mold core 210 are in contact with each other, and a receiving space is formed inside. The mold cavity 300 penetrates the upper mold core 110 and the lower mold core 210, and is arranged in the receiving space, and the product is injection molded inside the mold cavity 300. A nozzle 340 and a plurality of insert components are arranged in the mold cavity 300, wherein the first insert component 310 is arranged on the nozzle 340, the second insert component 320 is fork-shaped, and is arranged around the nozzle 340 and the first insert component 310 as the center, and the third insert component 330 is fork-shaped, and is arranged around the outside of the second insert component with the nozzle 340 and the first insert component 310 as the center.

[0036] It should be noted that the injection mold discontinued in the embodiment of the present application is also provided with a driving mechanism, which drives the first insert assembly 310 to be released from the mold in sequence, then drives the second insert assembly 320 to be released from the mold, and finally drives the third insert assembly 330 to be released from the mold, thereby releasing the space inside the cavity 300, so that the product has sufficient space to be released from the mold, and the product can be released from the mold without deformation or damage to the structure.

[0037] It is understandable that one or more cavities 300 may be provided in the accommodating space formed by the upper mold core 110 and the lower mold core 210. The embodiment of the present application may simultaneously injection mold products in multiple cavities 300. The present embodiment does not impose any limitation on the number of cavities 300.

[0038] Reference Figure 1 and Figure 2 As shown, in some embodiments, the driving mechanism includes a first brake plate 410, which is arranged on the top of the upper template 100, and the first brake plate 410 is connected to the first insert assembly 310, the second insert assembly 320 and the third insert assembly 330, and the first brake plate 410 is used to pull out the first insert assembly 310, the second insert assembly 320 and the third insert assembly 330.

[0039] It should be noted that the first brake plate 410 is connected to the first insert assembly 310, the second insert assembly 320 and the third insert assembly 330, so as to drive the first insert assembly 310, the second insert assembly 320 and the third insert assembly 330 by moving up and down. When the first brake plate 410 descends, the first insert assembly 310, the second insert assembly 320 and the third insert assembly 330 are reset into the cavity 300 to fill the internal space of the cavity 300. When the first brake plate 410 rises, the first insert assembly 310, the second insert assembly 320 and the third insert assembly 330 are pulled out of the cavity 300 to release the internal space of the cavity 300.

[0040] Reference Figure 1 and Figure 2 As shown, in some embodiments, the second insert component 320 abuts against the first insert component 310 , the third insert component 330 abuts against the second insert component 320 , and the first insert component 310 , the second insert component 320 , and the third insert component 330 fill the inner space of the cavity 300 .

[0041] It should be noted that the second insert assembly 320 abuts against and is in close contact with the first insert assembly 310, and the third insert assembly 330 abuts against and is in close contact with the second insert assembly 320, ensuring that there is no gap between the two insert assemblies, filling the internal space of the cavity 300, thereby forming a closed space of a special shape with only an input hole and an output hole, which is used to form a product of a special shape. The absence of a gap between the two insert assemblies can also ensure that the rubber material injected into the cavity 300 will not leak, preventing the rubber material from damaging the internal structure of the mold.

[0042] Reference Figure 1 and Figure 2 As shown, in some embodiments, the first insert assembly 310 is a male mold insert, used to cooperate with the nozzle 340 to form the shape of the injection molded product, and the second insert assembly 320 and the third insert assembly 330 are baffle plate inserts, and the second insert assembly 320 and the third insert assembly 330 are used to guide the flow direction of the rubber material.

[0043] It should be noted that the first insert assembly 310 is a male mold insert. During the injection molding process, the male mold insert is used to form a concave part in the product or a convex part in the product. The material selection and manufacturing process of the male mold insert also need to be considered according to the specific injection molding requirements to ensure that it can withstand the injection molding pressure, temperature and other influences during the injection molding production process, and maintain good wear resistance and stability.

[0044] It should be noted that the second insert assembly 320 is a baffle plate insert, and the third insert assembly 330 is a baffle plate insert.

[0045] It can be understood that in one embodiment of the present application, the rubber is injected into the interior of the cavity 300, and the second insert assembly 320 and the third insert assembly 330 restrict the flow of the rubber, ensuring that the rubber flows to the area between the first insert assembly 310 and the nozzle 340 during the die punching process, thereby forming a special shape of the product through the first insert assembly 310 and the nozzle 340.

[0046] Reference Figure 1 and Figure 2 As shown, in some embodiments, the driving mechanism is used to drive the first insert assembly 310 , the second insert assembly 320 , and the third insert assembly 330 to move along a preset direction.

[0047] It should be noted that the preset direction can be upward or downward, and the preset direction can be set according to actual conditions. In one embodiment, the driving mechanism pulls the first insert assembly 310, the second insert assembly 320 and the third insert assembly 330 to move upward in sequence, thereby releasing the internal space of the cavity 300, so that there is sufficient space during the process of leaving the mold, preventing the product from deformation or even damaging the product structure.

During the injection molding process of the product, the rubber is injected through the injection port 600 and injected into the cavity 300 through the injection pipe 700. In another embodiment, a plurality of cavities 300 are arranged in the accommodating space formed by the upper mold core 110 and the lower mold core 210, and the output end of the glue injection pipe 700 diverts the rubber to each cavity 300 through a plurality of diversion pipes.

[0050] Reference Figure 3 As shown, in some embodiments, the injection mold further includes a plurality of guide pillars 810 , and the upper mold plate 100 and the lower mold plate 200 both have a plurality of guide holes 820 , and the guide pillars 810 are fixedly connected to the upper mold plate 100 and the lower mold plate 200 through the guide holes 820 .

[0051] It should be noted that the guide hole 820 of the upper template 100 corresponds to the guide hole 820 of the lower template 200. One end of the guide post 810 is connected to the guide hole 820 of the upper template 100, and the other end is connected to the guide hole 820 of the lower template 200, ensuring the accurate alignment of the cavity 300 when the mold is closed, thereby improving the processing accuracy and consistency of the product. The guide post 810 is used to guide the closing and separation movements of the mold to ensure the precise positioning of the mold during the movement.

[0052] It is understandable that the number of guide posts 810, guide holes 820 of the upper template 100 and guide holes 820 of the lower template 200 corresponds, and one or more guide posts 810 corresponding to the guide holes 820 can be set according to actual usage.

[0053] Reference Figure 3 As shown, in some embodiments, the driving mechanism also includes a second brake plate 420 and an ejector pin 430. The second brake plate 420 is arranged at the bottom of the lower mold plate 200. One end of the ejector pin 430 is connected to the second brake plate 420, and the other end penetrates the cavity 300 to eject the injection molded product.

[0054] It should be noted that after the injection molding of the product is completed, the injection mold ejects the injection molded product through the second brake plate 420 and the ejector pin 430. In one embodiment, the driving mechanism pushes the two ejector pins 430 that penetrate the lower mold core 210 through the second brake plate 420 to eject the injection molded product, thereby achieving product demolding and avoiding damage to the mold or deformation of the product due to the plastic product being stuck in the mold.

[0055] It is understandable that the number of the second brake plate 420 and the ejector pin 430 can be set to one or more, depending on actual usage, and this embodiment does not impose any limitation.

One end of the reset mechanism 1000 is fixed to the second brake plate 420, and the other end is fixed to the base plate 900. The reset mechanism 1000 is used to reset the second brake plate 420 and the ejector pin 430.

[0057] It should be noted that, in one embodiment of the present application, after the injection-molded product is ejected by the ejector pin 430, the second brake plate 420 is dropped downward by the reset mechanism 1000, and at the same time, the ejector pin 430 also falls with the second brake plate 420 to return to the initial position and achieve reset. This ensures that the second brake plate 420 and the ejector pin 430 can be accurately reset to the specified position after each closing and opening of the mold, thereby ensuring the correct operation of the mold. In addition, the automated reset mechanism 1000 can reduce manual adjustment steps and improve the production efficiency of the mold.
