[0001] This invention relates to the field of injection mold technology, specifically to a high-efficiency molding mold with a balanced injection channel. Background Technology

[0002] Injection molds are precision manufacturing equipment used for the mass production of plastic products. They involve injecting molten plastic into a metal mold cavity, which then cools and solidifies to obtain the desired shape and size. Widely used in the automotive, home appliance, electronics, and daily necessities industries, injection molds are an indispensable key tool for "one-step molding and efficient production" in modern industry.

[0003] In existing technologies, when molten material is injected into the mold cavity, the flow channel is often unbalanced due to unreasonable injection method, resulting in low filling efficiency of molten material.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] In existing technologies, when molten material is injected into the mold cavity, the flow channel is often unbalanced due to unreasonable injection method, resulting in low filling efficiency of molten material. Furthermore, since the mold temperature is lower than the temperature of the molten material, the cooling is too fast during the filling process, leading to incomplete filling or internal stress, which affects the quality and performance of the final product.

[0020] In view of this, the present invention provides a high-efficiency molding die with a balanced injection runner. Through the cooperation of the fixed mold plate, side connecting plate, fixed mold plate, moving mold plate, moving mold plate, mold cavity, hot runner module and temperature control module, the injection mold adopts a symmetrically distributed X-shaped hot runner structure design. By preheating the mold before injection, the molten material is uniformly and quickly delivered to all parts of the mold cavity, and the molten material maintains stable fluidity and uniform temperature distribution in the mold cavity. This effectively reduces the residence time of the molten material in the runner and the time required for filling and molding, avoids incomplete filling or internal stress caused by excessively rapid cooling of the injection material, and improves production efficiency and product quality.

[0021] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0022] Depend on Figures 1-8 It is known that a high-efficiency molding die with a balanced injection channel includes a fixed mold plate 1. Two side connecting plates 2 are fixedly connected to one side of the fixed mold plate 1. A fixed mold plate 3 is fixedly connected to the side connecting plate 2 away from the fixed mold plate 1. A moving mold plate 4 is correspondingly arranged on the side of the fixed mold plate 1 located on the side of the fixed mold plate 3. A moving mold plate 5 is arranged on the side of the moving mold plate 4 close to the fixed mold plate 3. The moving mold plate 5 is connected to the fixed mold plate 3. A mold cavity 6 is arranged on the side of the moving mold plate 5 and the fixed mold plate 3 that are close to each other. The high-efficiency molding die with a molten runner also includes a hot runner module 7 and a temperature control module 8. The hot runner module 7 is located on the side where the moving mold fixing plate 4 and the moving mold plate 5 are close to each other; the temperature control module 8 is located on the side where the fixed mold fixing plate 1 and the fixed mold plate 3 are close to each other. The hot runner module 7 adopts a symmetrically distributed X-shaped hot runner structure design, which makes the molten material evenly delivered to all parts of the mold cavity 6. The temperature control module 8 precisely controls the mold temperature, so that the molten material maintains stable fluidity and uniform temperature distribution in the mold cavity 6.

[0023] In the specific implementation process, it is worth noting that the main structure of the molding die is formed by the cooperation between the fixed mold fixing plate 1, the side connecting plate 2, the fixed mold plate 3, the moving mold fixing plate 4, the moving mold plate 5, and the mold cavity 6. The fixed mold fixing plate 1 is fixed to the fixed end of the injection molding equipment, the fixed mold plate 3 is fixed to the stationary part of the injection molding equipment through the fixed mold fixing plate 1 and the side connecting plate 2, and the moving mold plate 5 is fixed to the moving part of the injection molding equipment through the moving mold fixing plate 4, realizing the opening and closing action of the mold. After the mold is closed, the mold cavity 6 located in the fixed mold plate 3 and the moving mold plate 5 forms a closed space for accommodating and molding molten material. The hot runner module 7 adopts a symmetrically distributed X-shaped hot runner structure design to ensure a more reasonable layout of the hot runner in the mold, so that the molten material is uniformly and quickly delivered to all parts of the mold cavity 6, effectively reducing the residence time of the molten material in the runner and reducing the time required for filling and molding. The temperature control module 8 is used to precisely control the mold temperature. By preheating the mold before injection, the molten material maintains stable fluidity and uniform temperature distribution in the mold cavity 6, preventing incomplete filling or internal stress caused by excessively rapid cooling of the injection material. After injection, the mold is cooled by circulating cooling medium, thereby achieving rapid demolding and improving production efficiency. Through the cooperation of the fixed mold fixing plate 1, side connecting plate 2, fixed mold plate 3, moving mold fixing plate 4, moving mold plate 5, mold cavity 6, hot runner module 7, and temperature control module 8, the injection mold adopts a symmetrically distributed X-shaped hot runner structure design. By preheating the mold before injection, the molten material is uniformly and quickly delivered to all parts of the mold cavity 6, and the molten material maintains stable fluidity and uniform temperature distribution in the mold cavity 6. This effectively reduces the residence time of the molten material in the runner and the time required for filling and molding, preventing incomplete filling or internal stress caused by excessively rapid cooling of the injection material, thus improving production efficiency and product quality.

[0024] Furthermore, the hot runner module 7 includes a hot runner profile 71, an X-shaped hot runner channel 72, a hot runner inlet 73, a lower outlet 74, and a hot runner nozzle 75. The hot runner profile 71 is fixedly connected to the moving mold fixing plate 4 and the moving mold plate 5 on the side where they are close to each other. The X-shaped hot runner channel 72 is formed on the outer wall of the hot runner profile 71 on the side close to the moving mold fixing plate 4. The hot runner inlet 73 is located on the top side of the hot runner profile 71 and is connected to the X-shaped hot runner channel 72. Two outlets 74 are provided at the bottom of the X-shaped hot runner channel 72; multiple hot runner nozzles 75 are provided, symmetrically distributed inside the mold cavity 6 located on the moving mold plate 5, and connected to the X-shaped hot runner channel 72; wherein, a hot runner channel for molten material is formed between the hot runner plate 71 and the moving mold fixing plate 4, and the molten material is transported to the inside of the X-shaped hot runner channel 72 through the hot runner injection port 73, and injected into the mold cavity 6 by the hot runner nozzles 75 with a balanced pressure and speed; In the specific implementation process, it is worth noting that, through the cooperation between the moving mold fixing plate 4, the moving mold plate 5, the hot runner plate 71, the X-shaped hot runner groove 72, the hot runner injection port 73, the lower outlet 74, and the hot runner nozzle 75, the flow channel of the hot melt material adopts an X-shaped symmetrical design. The molten material is injected into the X-shaped hot runner groove 72 through the hot runner injection port 73, and then injected into the mold cavity 6 through multiple symmetrically distributed hot runner nozzles 75. This ensures that the molten material can be evenly distributed when injected into the mold cavity 6, effectively avoiding the problem of uneven pressure caused by unreasonable flow channel layout, avoiding incomplete filling or internal stress, thereby improving the quality stability of the molded product. The lower outlet 74 is used to discharge the molten material remaining in the hot runner groove after injection molding, preventing the material from cooling and solidifying in the flow channel, which would affect the normal operation of the next injection molding operation.

[0025] Furthermore, the temperature control module 8 includes a temperature control tube fixing plate 81, a preheating temperature control tube 82, a cooling interface 83, and a temperature control tube drive assembly 84. The temperature control tube fixing plate 81 is located on one side of the fixed mold fixing plate 1 and the fixed mold plate 3 that are close to each other. Multiple preheating temperature control tubes 82 are provided and are fixedly connected at equal intervals to the side of the temperature control tube fixing plate 81 that is close to the fixed mold plate 3, and are also connected to the fixed mold plate 3. Multiple cooling interfaces 83 are provided and are distributed on one side of the fixed mold plate 3 and the moving mold plate 5. The temperature control tube drive assembly 84 is located on the side of the fixed mold fixing plate 1 that is close to the temperature control tube fixing plate 81. The preheating temperature control tube 82 preheats the fixed mold plate 3 through the flow of circulating medium. The cooling interface 83 is connected to an external cooling device and rapidly cools the mold through the flow of cooling medium, thereby realizing dynamic adjustment of the mold temperature. The temperature control tube drive assembly 84 enables the temperature control tube fixing plate 81 and the preheating temperature control tube 82 to move.

[0026] In the specific implementation process, it is worth noting that through the cooperation between the fixed mold plate 1, the fixed mold plate 3, the temperature control pipe fixed plate 81, the preheating temperature control pipe 82, and the cooling interface 83, before the molten material is injected into the mold cavity 6, the end of the preheating temperature control pipe 82 contacts the fixed mold plate 3, and the flow of circulating medium is used to preheat the fixed mold plate 3, so that the heat can be efficiently transferred to the fixed mold plate 3, thereby ensuring that the mold cavity 6 reaches the ideal preheating temperature before injection molding, effectively reducing molding defects caused by temperature difference during the injection of hot melt material. The cooling interface 83 is used to connect to external cooling equipment, and the mold is rapidly cooled by the circulation of cooling medium in the cooling channel inside the mold, thereby realizing the dynamic adjustment of the mold temperature, ensuring that the mold temperature can be quickly reduced after injection molding, facilitating the rapid demolding of the product, and improving production efficiency. The temperature control pipe drive assembly 84 is used to make the temperature control pipe fixed plate 81 move smoothly.

[0027] Furthermore, the temperature control tube drive assembly 84 includes a first guide post 841 and a first guide sleeve 842. Multiple first guide posts 841 are provided, distributed on both sides of the temperature control tube fixing plate 81, and fixedly connected to the fixed mold fixing plate 1. The first guide sleeve 842 is slidably connected to the outer wall of the first guide post 841 and fixedly connected to the inner wall of the temperature control tube fixing plate 81. Through the cooperation of the first guide post 841 and the first guide sleeve 842, the fixed mold fixing plate 1 can move smoothly, thereby enabling the preheating temperature control tube 82 to contact or separate from the fixed mold plate 3.

[0028] In the specific implementation process, it is worth noting that through the cooperation between the fixed mold plate 1, the temperature control tube plate 81, the first guide post 841 and the first guide sleeve 842, the temperature control tube plate 81 is connected to the external drive device of the injection molding equipment, so that the temperature control tube plate 81 can move between the side connecting plates 2, thereby realizing the precise movement control of the temperature control tube plate 81. This allows the preheating temperature control tube 82 to separate from the fixed mold plate 3 after the injection operation is completed, so as to quickly cool the mold.

[0029] Furthermore, the temperature control module 8 also includes multiple temperature probes 85, which are respectively connected to the inner walls of the fixed model plate 3 and the moving model plate 5.

[0030] In the specific implementation process, it is worth noting that the temperature sensing probe 85 is used to sense the temperature of the measuring model plate 3 and the moving model plate 5, and transmits the temperature signal to the external control system to realize real-time monitoring and precise adjustment of the mold temperature. The distribution of the temperature sensing probe 85 can fully cover the key areas of the mold, ensuring the accuracy and representativeness of the temperature data collection. Furthermore, a mold closing positioning module 9 is provided on the side of the fixed mold plate 3 and the moving mold plate 5 that are close to each other. The mold closing positioning module 9 includes a guide component 91, a limiting component 92, a locking module 93, and a sensing probe 94. The guide component 91 is located on the side of the fixed mold plate 3 that is close to the moving mold plate 5 and is located outside the mold cavity 6. The limiting component 92 is located on the side of the moving mold plate 5 that is close to the fixed mold plate 3 and is located outside the mold cavity 6. The locking module 93 is located on both sides of the outer wall of the fixed mold plate 3. Two sets of sensing probes 94 are provided and are respectively connected to the bottom of the fixed mold plate 3 and the moving mold plate 5. The guide component 91 plays a guiding role in the mold closing process and forms a limit through the limiting component 92 after mold closing to ensure that the fixed mold plate 3 and the moving mold plate 5 can be accurately aligned. The locking module 93 is used to lock the mold after mold closing.

[0031] In the specific implementation process, it is worth noting that the guide component 91 is used to guide the precise docking of the fixed mold plate 3 and the moving mold plate 5 during the mold closing process, reducing the mold closing error caused by position deviation. After the mold is closed, the limiting component 92 provides stable limiting to prevent mold displacement caused by external force or vibration. The locking module 93 further enhances the stability of the mold after closing through mechanical locking, ensuring that the mold will not loosen or misalign during the injection molding process, thereby improving the accuracy and consistency of the molded product. Through the cooperation between the fixed mold plate 3, the moving mold plate 5, the guide component 91, the limiting component 92, and the locking module 93, the fixed mold plate 3 and the moving mold plate 5 are precisely docked during the mold closing process, and the fixed mold plate 3 and the moving mold plate 5 are physically limited and mechanically locked after the mold is closed. This effectively avoids the displacement of the mold caused by uneven force or external interference during the injection molding process, improves the mold closing accuracy, and significantly enhances the overall stability of the mold, thus providing a reliable guarantee for the production of high-quality molded products.

[0032] Furthermore, the guide assembly 91 includes a second guide post 911, a fixing hole 912, a second guide sleeve 913, and a limiting clip 914. Two sets of second guide posts 911 are fixedly connected to the outer wall of the fixed mold plate 3, located on both sides of the outer surface of the mold cavity 6. Two sets of fixing holes 912 are provided, opened on the outer wall of the moving mold plate 5, located on both sides of the outer surface of the mold cavity 6, and correspondingly positioned on the second guide posts 911. The second guide sleeve 913 is fitted to the inner wall of the fixing hole 912 and slidably connected to the outer wall of the second guide post 911. The limiting clip 914 is fixedly connected to the inside of the fixing hole 912 and fitted to the second guide sleeve 913. The second guide sleeve 913 is installed inside the fixing hole 912 via the limiting clip 914. During mold opening and closing, the cooperation between the second guide post 911 and the second guide sleeve 913 ensures precise alignment between the moving mold plate 5 and the fixed mold plate 3.

[0033] In the specific implementation process, it is worth noting that the second guide sleeve 913 is installed in the fixing hole 912 of the moving model plate 5 through the limiting card 914. During the mold opening and closing process, the second guide sleeve 913 slides on the outer wall of the second guide post 911, thereby guiding the moving model plate 5 and the fixed model plate 3 to achieve precise docking, ensuring the stability of the mold during the opening and closing process.

[0034] Furthermore, the limiting component 92 includes a limiting groove 921 and a limiting protrusion 922. Two sets of limiting grooves 921 are provided, distributed on both sides of the moving mold plate 5 located in the mold cavity 6. Two sets of limiting protrusions 922 are provided, distributed on both sides of the fixed mold plate 3 located in the mold cavity 6, and are connected to the inner wall of the limiting groove 921. The cooperation of the limiting groove 921 and the limiting protrusion 922 can improve the stability of the moving mold plate 5 and the fixed mold plate 3 after mold closing, and prevent the mold from shifting or misaligning during injection molding.

[0035] In the specific implementation process, it is worth noting that through the cooperation between the fixed mold plate 3, the moving mold plate 5, the limiting groove 921 and the limiting protrusion 922, after the mold is closed, the limiting protrusion 922 is embedded in the limiting groove 921 to form a stable limiting structure, which can effectively enhance the mold's anti-interference ability during the injection molding process and avoid mold displacement problems caused by external vibration or pressure changes.

[0036] Furthermore, the locking module 93 includes a locking block 931, a locking hole 932, and a locking bolt 933. Two sets of locking blocks 931 are provided, which are rotatably connected to both sides of the fixed mold plate 3. The locking hole 932 is located on the side of the locking block 931 away from the fixed mold plate 3. The locking bolt 933 is fitted to the inner wall of the locking hole 932 and threaded to the inner wall of the moving mold plate 5. Through the cooperation of the locking block 931, the locking hole 932, and the locking bolt 933, the fixed mold plate 3 and the moving mold plate 5 can be firmly locked after the mold is closed, preventing the mold from loosening or separating during injection molding or movement.

[0037] In the specific implementation process, it is worth noting that through the cooperation between the fixed mold plate 3, the moving mold plate 5, the locking block 931, the locking hole 932 and the locking bolt 933, after the mold is closed, by inserting the locking bolt 933 into the locking hole 932 and screwing it into the screw hole of the moving mold plate 5, the fixed mold plate 3 and the moving mold plate 5 are firmly locked, ensuring that the mold remains highly stable during the injection molding process and effectively preventing the mold from loosening due to equipment vibration or changes in internal pressure.

[0038] The working principle of this application is illustrated below with a preferred embodiment: In actual operation, when the injection molding equipment is started, the fixed mold plate 3 and the moving mold plate 5 are closed under the action of the external drive device. The fixed mold plate 3 and the moving mold plate 5 are locked by the locking module 93, so that the mold cavity 6 forms a stable closed space. The preheating temperature control tube 82 preheats the mold before injection molding. It transfers heat to the fixed mold plate 3 through the flow of circulating medium, so that the mold cavity 6 reaches the ideal preheating temperature. The temperature of the fixed mold plate 3 and the moving mold plate 5 are monitored in real time by the temperature sensor 85, and the temperature signal is transmitted to the external control system. After the mold temperature reaches the set value, the injection molding equipment delivers the molten material through the hot runner injection port 73 to the X-type hot runner channel 72. The molten material flows in the X-type hot runner channel 72 with a balanced pressure and speed to each hot runner nozzle 75 and is injected into the mold cavity 6 through the hot runner nozzle 75. After the injection molding process is completed, the temperature control tube fixing plate 81 is moved to separate the preheating temperature control tube 82 from the fixed mold plate 3. Then, the cooling medium is delivered to the cooling channel of the fixed mold plate 3 and the moving mold plate 5 through the cooling interface 83 for circulation cooling, so that the mold temperature drops rapidly, which facilitates the rapid molding of the injection molded product. During the cooling process, the temperature sensing probe 85 continuously monitors the mold temperature change and feeds back the real-time data to the external control system. The external control system adjusts the flow rate and temperature of the cooling medium according to the feedback data. When the mold temperature drops to the set value, the mold opening operation can be performed.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
