Description

Technical Field

[0001] This invention relates to the field of plastic molding die technology, and more specifically to a hot runner die. Background Technology

[0002] Hot runner molds are molds that use heating devices to prevent the melt inside the runner from solidifying. Because they have a shorter forming cycle than traditional molds and save more raw materials, they are widely used.

[0003] In the current field of plastic injection molding, traditional hot runner molds have many problems that limit production efficiency and application flexibility. The mold core is mostly rigidly connected to the mold frame by bolts, which is cumbersome to replace and easily affects the molding due to insufficient positioning accuracy. It also has poor adaptability. The inner walls of components such as the manifold and hot nozzle of the hot runner system are prone to residual mother liquor. When changing materials or colors, a large amount of washing material is required to flush it. Demolding mostly relies on cylinders or hydraulic cylinders, resulting in low ejection accuracy and easy damage to the workpiece. The wiring harness of the hot runner lacks a special management structure, which is prone to knotting, wear or falling off, affecting the overall reliability of the equipment.

[0004] To address these issues, this invention proposes a hot runner mold. Summary of the Invention

Furthermore, multiple sets of locking blocks are processed in a rectangular array at equal intervals on the right side of the fixed mold frame.

[0015] As a further embodiment of the present invention, the mold core fixing mechanism includes multiple punches, which are respectively engaged with the right side of the fixed mold frame by locking blocks. A locking bracket 1 is fastened to the outer side of the multiple punches. The locking bracket 1 is engaged with the flange groove opened on the outer side of the right side of the fixed mold frame and is bolted together with the right side of the fixed mold frame.

The top plate can be fitted into the inner right side of the punches. The inner expansion sleeve extends through the center of the inner die core.

[0016] The beneficial effects of this invention are:

[0017] (1) Through the coordinated operation of the fixed mold assembly, the moving mold assembly and the mold core fixing mechanism, the fixed mold assembly forms a stable support system through the fixed base plate and the I-plate, and the moving mold assembly ensures that the components are tightly connected through the sliding base plate and the connecting piece; the primary hot runner of the hot runner assembly fits tightly with the main runner, and the nozzle and the cavity mold core slot are precisely matched to avoid leakage of the injection molding liquid and ensure the sealing and stability of the injection molding process; the punch is initially fixed by the right side of the fixed mold frame and then locked by the first snap-fit ​​bracket; the cavity mold core is fixed to the moving mold frame through the second snap-fit ​​bracket. When replacing, only the corresponding snap-fit ​​bracket needs to be removed, without disassembling the entire mold assembly. The punch or cavity mold core can be replaced separately, which greatly reduces the difficulty and time cost of mold replacement for multi-specification workpiece production.

[0018] (2) Through the cooperation of the fixed mold assembly and the insert rod, when the mold is closed, the insert rod of the moving mold assembly automatically passes through the through hole of the fixed mold frame and squeezes the support plate, so that the top piece shrinks into the inside of the punch, avoiding interference with the molding of the injection cavity; when the mold is separated, after the insert rod is removed, the return spring plate pushes the support plate, cross bar and top piece to move to the right synchronously through the rebound force, and the top piece automatically ejects the workpiece from the punch, realizing seamless linkage between the demolding action and the mold separation action, without the need for additional manual or power intervention; the guide post provides precise guidance for the sliding of the support plate, and the rebound force of the return spring plate is stable and controllable, ensuring the consistency of each demolding action of the top piece, reducing workpiece damage or mold jamming problems caused by demolding deviation.

[0019] (3) By cooperating with the fixed components, the installation slot plate opens the wire management slot, and with the support bar, spring telescopic rod and buckle, the wire harness of the hot runner assembly can be clamped and fixed to prevent the wire harness from getting tangled, loose or worn during the mold movement, ensuring the stability of the electrical connection of the hot runner and reducing downtime caused by wire harness failure.

[0020] (4) Through the operation of the hot runner assembly, the manifold and the inner wall of the secondary hot nozzle are coated with a high temperature resistant modified superhydrophobic coating, which greatly reduces the residual adhesion of the injection molding masterbatch melt. Daily cleaning only requires a small amount of cleaning material or compressed air to complete the task, avoiding workpiece defects caused by incomplete cleaning of residue. The manifold and the secondary hot nozzle have built-in heating coils. When changing the masterbatch material or color, the internal residual masterbatch can be heated to a temperature much higher than the plastic decomposition temperature, and the residue can be quickly removed by ablation cleaning without the need for a large amount of cleaning material to rinse, reducing downtime and waste of cleaning material.

Detailed Implementation

[0037] 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.

[0038] Example 1, please refer to Figures 1-7 As shown, the present invention is a hot runner mold, including a fixed mold assembly 1, a movable mold assembly 2 disposed on the right side of the fixed mold assembly 1, and a mold core fixing mechanism 3 disposed on the inner side of the fixed mold assembly 1 and the movable mold assembly 2. The mold core fixing mechanism 3 is used to fix the punch core 301 and the die core 303. Through the mutual cooperation of the fixed mold assembly 1, the movable mold assembly 2 and the mold core fixing mechanism 3, plastic masterbatch can be injection molded into finished workpieces.

[0039] The fixed mold assembly 1 includes a fixed base plate 101, which is used to fix and support the I-beam plate 102. The I-beam plate 102 is fixedly connected to the right side of the fixed base plate 101. The I-beam plate 102 is used to fix the guide pillars 103 and the return spring plate 104. Guide pillars 103 are fixedly connected to the four corners of the right side of the I-beam plate 102. The guide pillars 103 are used to fix and support the fixed mold frame 105 and allow the support plate 106 to slide on its outer wall. The return spring plate 104 is fixedly connected to the center of the right side of the I-beam plate 102. The return spring plate 104 is used to press the support plate 106 of the crossbar 107 and reset the support plate 106 after it slides to the left, so that it can re-fit to the left side of the fixed mold frame 105. The right sides of the multiple guide pillars 103 are connected to the fixed mold by bolts. The frame 105, the fixed mold frame 105 is used to snap the punch core 301 and the snap-fit ​​frame 302. The right side of the outer wall of multiple guide pillars 103 is slidably connected to the support plate 106. The support plate 106 is used to fix and support the crossbar 107. Multiple crossbars 107 are fixedly fixed in a rectangular array at equal intervals on the right side of the support plate 106. The crossbars 107 are used to support the top plate 108. Each crossbar 107 is threaded to the right side of the top plate 108. The top plate 108 is used to eject and demold the cooled and formed injection molded workpiece. The fixed mold assembly 1 and the moving mold assembly 2 are symmetrically arranged on the same horizontal line. The left side of the support plate 106 is pressed against the right side of the return spring plate 104, and the right side of the support plate 106 is attached to the left side of the fixed mold frame 105. Multiple crossbars 107 pass through the inside of the fixed mold frame 105.

[0040] In this embodiment, preferably, flange grooves are provided on the outer right side of the fixed mold frame 105 and the outer left side of the moving mold frame 206. The flange grooves are used to engage the first snap-fit ​​bracket 302 and the second snap-fit ​​bracket 304. Square through holes, adapted to the outer contour of the fixed mold frame 105, are provided at positions corresponding to the multiple insert rods 210 on the right side. After the fixed mold assembly 1 and the moving mold assembly 2 are closed, the insert rods 210 will penetrate through the square through holes, thereby pressing the support plate 106. This causes the top plate 108 to retract into the inner right side of the punch core 301 via the support plate 106 and the crossbar 107. When the fixed mold assembly 1 and the moving mold assembly 2 are separated, the insert rods 210 will release their pressure on the support plate 106. The extrusion of 06, through the rebound force generated by the deformation of the return spring plate 104, resets the support plate 106, thereby causing the support plate 106 to re-fit against the left side of the fixed mold frame 105, which in turn allows the top piece 108 to be ejected from the inside of the punch 301. At the same time as the top piece 108 is ejected from the inside of the punch 301, the cooled and molded injection molded part can be demolded. The right side of the fixed mold frame 105 is processed with multiple sets of locking blocks in a rectangular array at equal intervals. The locking blocks are used to lock the punch 301, thereby initially fixing the individual punch 301, which is convenient for subsequent fixing of the punch 301 by the locking bracket 302, and facilitates the replacement of the punch 301.

[0041] In summary, when assembling the fixed mold assembly 1, first connect the I-plate 102 to the right side of the fixed base plate 101 with bolts. After fixing the I-plate 102, first fit the support plate 106 onto the outer wall of the guide post 103 fixed at the four corners on the right side of the I-plate 102. Then, connect the fixed mold frame 105 to the guide post 103 with bolts. Before connecting the fixed mold frame 105 to the guide post 103, multiple crossbars 107 on the right side of the support plate 106 will pass through the interior of the fixed mold frame 105. Then, sequentially snap the punch 301 in the mold core fixing mechanism 3 to the right side of the fixed mold frame 105 to initially fix the punch 301 and secure it. After fixing the punch 301, snap-fit ​​bracket 302 is inserted into the flange groove on the outer right side of the fixed mold frame 105, and then bolted to the fixed mold frame 105. Finally, the top plate 108 is threaded to the right side of the outer wall of the crossbar 107, thus completing the assembly of the fixed mold assembly 1 and the punch 301. When it is necessary to replace the punch 301 with a different specification, snap-fit ​​bracket 302 is removed from the right side of the fixed mold frame 105, canceling the snap-fit ​​bracket 302 on the punch 301. Then, the punch 301 that needs to be replaced can be replaced. This facilitates the installation and disassembly of the punch 301. During the mold closing stage, the fixed mold assembly 1 and the moving mold assembly... When the moving mold assembly 2 closes along the same horizontal line, the insert rod 210 in the moving mold assembly 2 will align with the square through hole on the fixed mold base 105 and pass through it, directly pressing the support plate 106 located on the outer wall of the guide post 103. After being pressed, the support plate 106 slides to the left along the guide post 103, while simultaneously compressing the return spring plate 104 in the center of the die plate 102. As the support plate 106 moves, the crossbar 107 connected to it drives the top plate 108 to retract to the left in sync, eventually causing the top plate 108 to be housed inside the right side of the punch core 301, avoiding interference with the molding of the workpiece during the injection molding process. During the mold parting stage, the fixed mold assembly 1 and the moving mold assembly 2 separate, and the insert rod 210 is removed with the moving mold assembly 2. The compression of the support plate 106 is released, and the compressed return spring plate 104 releases its rebound force, pushing the support plate 106 to slide to the right along the guide post 103 until it re-fits the left side of the fixed mold frame 105. At the same time as the support plate 106 resets, it will drive the cross bar 107 and the top plate 108 to move to the right simultaneously. The top plate 108 will be ejected from the inside of the punch 301, and the cooled and formed injection molded part will be ejected from the inside of the right side of the punch 301, realizing the demolding operation. Throughout the process, the fixed base plate 101, the I-plate 102, the guide post 103 and other components always provide stable support and guidance, ensuring that the movement of each moving part is precise and controllable, thereby efficiently completing the cycle of injection molding and demolding.

Two spring telescopic rods 2029 are symmetrically fixed to the left side of each support bar 2026. The spring telescopic rods 2029 are used to support the pressure buckle 20210 and can compress the pressure buckle 20210. Each set of springs... The left side of the telescopic rod 2029 is fixed with a snap fastener 20210. The snap fastener 20210 is used to press the wire harness of the hot runner assembly 203 to prevent the wire harness from moving out of the inside of the wire management groove. The mounting plate 2021 can be connected to the left side of the sliding seat plate 201 by bolt thread. The top left side and bottom left side of the mounting plate 2021 are connected to the right side thread of the connecting piece 207 by bolt thread. The protrusion 2022 can be inserted into the slots opened at the front and rear ends of the right side of the moving mold frame 206, and the inner side of the two inserts 208 can be engaged and connected with the outer side of the two protrusions 2022.

[0045] In this embodiment, preferably, multiple cable management channels are symmetrically opened at the front and rear ends of the right side of the mounting plate 2021. Multiple clips 20210 are arranged on the right side of the cable management channels, and the left side of the clips 20210 is parallel to the right side of the cable management channels. The wire harness of the hot runner assembly 203 is snapped into the inside of the cable management channels, and the end of the wire harness of the hot runner assembly 203 is connected to the junction box 204. The left side of each clip 20210 is snapped onto the right side of the outer wall of the wire harness of the hot runner assembly 203.

[0046] In this embodiment, preferably, the hot runner assembly 203 includes a heat insulation plate 2031, which separates the manifold 2034 from the mounting groove plate 2021. A fixing plate 2032 is bolted to the right side of the heat insulation plate 2031. The fixing plate 2032, through its cooperation with the heat insulation plate 2031, clamps and fixes the heat insulation plate 2031 to the left side of the mounting groove plate 2021. A primary hot runner nozzle 2033 is provided at the center of the right side of the fixing plate 2032. The primary hot runner nozzle 2033 is connected to the main flow channel 205 and can deliver the injection molding masterbatch into it. A manifold 2034 is fixed to the left side of the heat insulation plate 2031. The manifold 2034 is used to control the flow of liquid entering the primary hot runner nozzle 2033. The injection molding masterbatch is diverted and evenly distributed to the interior of each secondary hot nozzle 2035. Multiple secondary hot nozzles 2035 are fixedly fixed in a rectangular array at equal intervals on the left side of the diverter plate 2034. These secondary hot nozzles 2035 are used to extrude the injection molding masterbatch. Each secondary hot nozzle 2035 has a nozzle 2036 threadedly connected to its left side via a flange. The nozzle 2036 is used to fix the inner expansion sleeve 2037 and can engage the right side of the die core 303. An inner expansion sleeve 2037 is fixedly attached to the center of each nozzle 2036. The inner expansion sleeve 2037 supports the ejector pin 2038, allowing it to slide inside and extrude the injection molding masterbatch into the interior of the die core 303. Each inner expansion sleeve 2037 has a slidingly connected ejector pin 2038 inside. The ejector pin 2038 is used to compress the inner wall of the inner expansion sleeve 2037. When the ejector pin 2038 slides to the right, it can release the blockage on the left side of the inner expansion sleeve 2037, thereby allowing the injection molding masterbatch to be extruded from the left side of the inner expansion sleeve 2037. Each secondary hot nozzle 2035 has a sleeve 2039 snapped into the left side inside. The sleeve 2039 is used to support the slide tube 20310, allowing the slide tube 20310 to slide left and right inside the sleeve 2039. Each sleeve 2039 has a slidingly connected slide tube 20310 inside the right side. The slide tube 20310 is used to compress the irregularly shaped slider 20313, thereby driving the ejector rod through the irregularly shaped slider 20313. 20311 moves, and the right side of the outer wall of the slide tube 20310 is attached to the inner wall of the secondary hot nozzle 2035. After the injection molding masterbatch enters the interior of the secondary hot nozzle 2035, it will squeeze the right side of the slide tube 20310, thereby pushing the slide tube 20310 to slide to the left. After the slide tube 20310 slides to the left side of the inside of the sleeve 2039, the injection molding masterbatch will enter the interior of the guide groove 20315. Each ejector pin 2038 has a ejector rod 20311 fixedly connected to its right side. The ejector rod 20311 is used to drive the ejector pin 2038 to move, and the right side of the outer wall of the ejector rod 20311 is slidably connected to the left side of the inside of the sleeve 2039. A limit sleeve 20312 is fixedly connected to the center of the left side of the inside of each sleeve 2039.The limiting sleeve 20312 is used to limit the movement trajectory of the push rod 20311 and the irregular slider 20313. The right side of the outer wall of the push rod 20311 is slidably connected to the inside of the limiting sleeve 20312. The irregular slider 20313 is slidably connected to the inside of the right side of the outer wall of each push rod 20311. The irregular slider 20313 is used to drive the push rod 20311 to move. When the slide tube 20310 slides to the left, it will push the irregular slider 20313 to slide inside the push rod 20311, thereby driving the push rod 20311 to slide to the right. Then, the push rod 20311 will drive the ejector pin 2038 to move to the right, so that the ejector pin 2038 will release the blockage on the left side of the inner expansion sleeve 2037. Conversely, when the slide tube 20310 slides to the right, it will drive the irregular slider 20313 to move to the right. 0313 also slides in the opposite direction inside the push rod 20311, thereby driving the push rod 20311 to reset to the left. This, in turn, drives the ejector pin 2038 to re-press into the inner left side of the inner expansion sleeve 2037. The top and bottom ends of the irregularly shaped slider 20313 are respectively attached to the top and bottom ends of the left side of the inner wall of the slide tube 20310. Each push rod 20311 and each slide tube 20310 has a support spring 20314 fixedly connected to its inner side. The support spring 20314 is used to reset the slide tube 20310. Each secondary hot nozzle 2035 has multiple guide grooves 20315 arranged in a ring array at equal intervals on its inner left side. The guide grooves 20315 are used to transport the injection molding masterbatch, and the left side of the guide grooves 20315 is connected to the inner left side of the inner expansion sleeve 2037.

[0047] In this embodiment, preferably, the right side of the heat insulation plate 2031 is attached to the left side of the mounting slot plate 2021, the fixing plate 2032 is fitted inside the fitting groove 2023 opened on the right side of the mounting slot plate 2021, and the heat insulation plate 2031 and the mounting slot plate 2021 are locked together by bolts, and the mounting slot plate 2021 is also fitted to the left side of the sliding seat plate 201 by bolts. The right side of the primary hot runner nozzle 2033 is tightly attached to the left side of the main flow channel 205, the moving mold frame 206 is sleeved on the left side of the outer wall of the hot runner assembly 203, and multiple secondary hot runner nozzles 2035 pass through the interior of the moving mold frame 206.

[0048] In this embodiment, preferably, the inner walls of the manifold 2034 and the multiple secondary hot nozzles 2035 are coated with a high-temperature resistant modified superhydrophobic coating, which can greatly reduce the adhesion of melt residue. Efficient cleaning can be achieved by combining a small amount of cleaning material or compressed air. A spiderweb-like groove is formed on the left side of the manifold 2034, and a spiral groove is formed on the outer wall of each secondary hot nozzle 2035. Heating coils are wound inside both the spiderweb-like grooves and the spiral grooves, which can normally heat the manifold 2034 and the secondary hot nozzles 2035. The heat preservation system keeps the injection molding masterbatch in a molten state. When it is necessary to change the injection molding masterbatch material or color, the heating coil can heat the injection molding masterbatch inside the manifold 2034 and the secondary hot nozzle 2035 to a temperature far above the plastic decomposition temperature, achieving ablation cleaning. This saves on cleaning materials and can quickly clean the inside of the manifold 2034 and the secondary hot nozzle 2035, enabling rapid switching of injection molding masterbatch material or color. This greatly reduces downtime and waste of cleaning materials, thereby improving production efficiency.

[0049] In summary, when assembling the moving mold assembly 2, first connect the mounting plate 2021 to the left side of the sliding seat plate 201 with bolts. Then, attach the heat insulation plate 2031 to the left side of the mounting plate 2021. Next, fit the fixing plate 2032 into the fitting groove 2023 on the right side of the mounting plate 2021. Use bolts to lock the heat insulation plate 2031, the fixing plate 2032, the mounting plate 2021, and the sliding seat plate 201 together. At this time, the right side of the primary hot runner nozzle 2033 is tightly fitted with the left side of the main runner 205, ensuring that the injection molding masterbatch can flow smoothly from the main runner 205 into the primary hot runner nozzle 2033. Then, fit the moving mold frame 206 onto the left side of the outer wall of the hot runner assembly 203, so that multiple secondary hot runner nozzles... 2035 extends through the interior of the moving mold frame 206. The connecting piece 207 is threadedly connected to the mounting slot plate 2021 and the moving mold frame 206 respectively by bolts, achieving a stable connection between the mounting slot plate 2021 and the moving mold frame 206. Then, the insert block 208 is inserted into the protrusion 2022 inside the right side of the moving mold frame 206 through the slot. The cover plate 209 is then used to press the insert block 208 tight, and the cover plate 209 is fixed to the moving mold frame 206 by bolts, ensuring a tight connection between the insert block 208 and the protrusion 2022. When organizing the wiring harness of the hot runner assembly 203, the wiring harness is first clipped into the symmetrically opened cable management slots at the front and rear ends of the right side of the mounting slot plate 2021. The end of the wiring harness is connected to the junction box 204. Then, the lever at the bottom of the support bar 2026 is turned. Block 2027 causes the support bar 2026 to rotate around the shaft 2024, engaging the buckle 2028 at the bottom of the support bar 2026 with the clamping rod 2025. At this time, the spring telescopic rod 2029 will squeeze the buckle 20210, causing the left side of the buckle 20210 to engage with the right side of the outer wall of the wire harness in the hot runner assembly 203, preventing the wire harness from moving out of the cable tray, thus completing the arrangement and fixation of the wire harness. During the injection molding process, the injection molding masterbatch enters the primary hot nozzle 2033 from the main channel 205, and then flows into the distributor plate 2034. The distributor plate 2034 will evenly distribute the injection molding masterbatch to each secondary hot nozzle 2035. When the injection molding masterbatch enters the interior of the secondary hot nozzle 2035, it will squeeze the right side of the slide tube 20310, pushing the slide tube 20310. Sliding tube 20310 slides to the left, and after sliding to the left side of the sleeve 2039, the injection molding masterbatch enters the guide groove 20315. Simultaneously, slide tube 20310 pushes the shaped slider 20313 to slide inside the ejector pin 20311, causing the ejector pin 20311 to slide to the right. This, in turn, causes the ejector pin 2038 to move to the right, releasing the seal on the left side of the inner expansion sleeve 2037. The injection molding masterbatch is then extruded from the left side of the inner expansion sleeve 2037 and enters the cavity core 303 through nozzle 2036 for injection molding. When injection molding is complete and demolding is required, the moving mold assembly 2 and the fixed mold assembly 1 separate along the same horizontal line. The insert rod 210 in the moving mold assembly 2 will retract with the moving mold assembly 2.The compression of the support plate 106 is released, and the compressed return spring disc 104 releases its rebound force, pushing the support plate 106 to slide to the right along the guide post 103. This causes the crossbar 107 and the top plate 108 to move to the right simultaneously. The top plate 108 is ejected from the inside of the punch 301, pushing the cooled and molded injection molded part out from the inside right side of the punch 301, thus achieving the demolding operation. After the process of extruding the injection molding masterbatch into the die 303 is completed, the supply of injection molding masterbatch into the secondary hot nozzle 2035 is stopped. After the injection extrusion stops, the support spring 20314 in the secondary hot nozzle 2035 will reset the slide tube 20310, causing the irregularly shaped slider 20313 to slide in the opposite direction, causing the ejector rod 20311 and ejector pin 2038 to reset to the left, and re-extruding to the inside left side of the inner expansion sleeve 2037, for the next... Once injection molding is complete, the entire hot runner mold efficiently completes the injection molding and demolding cycle through the coordinated work of its components. When it is necessary to change the injection masterbatch material or color, the inner walls of the manifold 2034 and multiple secondary hot nozzles 2035 are coated with a high-temperature modified superhydrophobic coating, which greatly reduces melt residue adhesion. Combined with a small amount of cleaning fluid or compressed air, efficient cleaning is possible. With the help of heating coils, the injection masterbatch inside the manifold 2034 and secondary hot nozzles 2035 can be heated to a temperature far exceeding the plastic decomposition temperature, achieving ablative cleaning. This saves cleaning fluid while quickly cleaning the interior of the manifold 2034 and secondary hot nozzles 2035, enabling rapid switching of injection masterbatch material or color, reducing downtime and cleaning fluid waste, and improving production efficiency.

[0050] Example 3, please refer to Figure 1 , Figure 2 and Figures 5-8 As shown, based on Embodiment 1 and Embodiment 2, the mold core fixing mechanism 3 includes multiple punches 301. The multiple punches 301 are respectively engaged with the right side of the fixed mold frame 105 by locking blocks. A locking bracket 302 is fastened to the outer side of the multiple punches 301. The locking bracket 302 is engaged inside a flange groove opened on the outer right side of the fixed mold frame 105 and is bolted to the right side of the fixed mold frame 105. Multiple die cores 303 are symmetrically arranged on the right side of the multiple punches 301. The outer side of the die core 303 is fastened with a snap-fit ​​bracket 304. Each die core 303 has a slot on its right side that matches the left side of the nozzle 2036. The right side of the snap-fit ​​bracket 304 is snapped into the flange groove on the outer side of the left side of the moving mold frame 206. It is also bolted to the left side of the moving mold frame 206. The top plate 108 can be fitted into the right side of the die core 301. The inner expansion sleeve 2037 passes through the center of the die core 303.

[0051] Example 4, please refer to Figures 1-15As shown, this embodiment is obtained by combining Embodiment 1, Embodiment 2 and Embodiment 3. In terms of assembly, the installation and fit of the mold core fixing mechanism 3, the fixed mold assembly 1 and the moving mold assembly 2 are more compact. Multiple punches 301 are securely locked to the right side of the fixed mold frame 105 by the locking block. The locking bracket 1 302 further strengthens the connection between the punches 301 and the fixed mold frame 105, ensuring that the punches 301 will not shift during the injection molding process. Similarly, multiple cavities 303 are tightly connected to the moving mold frame 206 by the locking bracket 2 304. The locking groove on the right side of the cavities 303 is precisely matched with the left side of the outer wall of the nozzle 2036, ensuring that the injection molding masterbatch can be accurately injected into the cavity of the cavities 303 from the nozzle 2036.

[0052] During the injection molding process, the working efficiency and stability of the hot runner assembly 203 are further improved. The injection masterbatch enters the primary hot nozzle 2033 from the main channel 205, and then is evenly distributed to each secondary hot nozzle 2035 through the manifold 2034. Since the inner walls of the secondary hot nozzles 2035 and the manifold 2034 are coated with a high-temperature resistant modified superhydrophobic coating, the adhesion of melt residue is greatly reduced. At the same time, the heating coil can accurately heat the injection masterbatch as needed. When it is necessary to change the injection masterbatch material or color, the heating coil can heat the injection masterbatch in the secondary hot nozzles 2035 and the manifold 2034 to a temperature far higher than the plastic decomposition temperature to achieve ablation cleaning. With the help of a small amount of cleaning material or compressed air, the cleaning work can be completed quickly, reducing downtime and waste of cleaning material.

[0053] During the demolding process, when the moving mold assembly 2 and the fixed mold assembly 1 separate along the same horizontal line, the insert rod 210 in the moving mold assembly 2 releases the pressure on the support plate 106, the reset spring plate 104 releases the rebound force, pushes the support plate 106 to slide to the right along the guide post 103, and drives the cross bar 107 and the top plate 108 to move to the right simultaneously. The top plate 108 is ejected from the inside of the punch 301, and the cooled and molded injection molded part is smoothly ejected from the inside of the right side of the punch 301, making the whole demolding process smoother.

[0054] Furthermore, the cooperation between the cable management channel on the right side of the mounting plate 2021 and the snap fastener 20210 effectively avoids the mess and displacement of the wire harness, ensuring the stability of the electrical connection of the hot runner assembly 203. At the same time, the coordinated work of components such as the support bar 2026, the spring telescopic rod 2029, and the snap fastener 20210 in the fixing component 202 further improves the reliability of the wire harness fixing. Through the close cooperation and coordinated work of each component, the entire hot runner mold achieves efficient injection molding and demolding cycles, improving production efficiency.

[0055] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the present invention should still fall within the scope of the present invention.
