Description

Technical Field

[0001] The present invention relates to the technical field of plastic molding molds, in particular to a hot runner mold. Background Art

[0002] Hot runner molds use a heating device to prevent the melt in the runner from solidifying. They are widely used because they have a shorter molding cycle than traditional molds and save more raw materials.

[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 molding due to insufficient positioning accuracy. The adaptability is poor, and the inner walls of the manifold, hot nozzle and other components of the hot runner system are prone to residual mother liquor. When changing materials or colors, a large amount of washing material is required for flushing. Demolding mostly relies on cylinders or hydraulic cylinders for drive, with low ejection accuracy and easy damage to workpieces. The hot runner harness lacks a special organization structure and is prone to knotting, wear or falling off, affecting the overall reliability of the equipment.

[0017] (3) Through the cooperation of the fixed components, the slot plate is installed to open the wire management slot, and the support bar, spring telescopic rod and buckle are used to clamp and fix the wiring harness of the hot runner assembly to prevent the wiring harness from being tangled, loosened or worn during the movement of the mold, thereby ensuring the stability of the hot runner electrical connection and reducing downtime caused by wiring harness failure.

[0018] (4) Through the operation of the hot runner assembly, the inner wall of the manifold and the secondary hot nozzle is coated with a high-temperature resistant modified super-hydrophobic coating, which greatly reduces the residual adhesion of the injection molding mother liquid melt. Daily cleaning can be completed with a small amount of washing material or compressed air to avoid workpiece defects caused by incomplete residual cleaning. The manifold and the secondary hot nozzle are built-in heating coils. When the mother liquid material or color is changed, the internal residual mother liquid can be heated to a temperature far higher than the decomposition temperature of the plastic. The residue is quickly removed by ablation cleaning, without the need for a large amount of washing material flushing, reducing downtime and washing material waste. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0022] For example 1, please refer to Figure 1-Figure 7 As shown, the present invention is a hot runner mold, including a fixed mold assembly 1, a movable mold assembly 2 is provided on the right side of the fixed mold assembly 1, and a mold core fixing mechanism 3 is provided 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 male mold core 301 and the female mold core 303. Through the mutual cooperation of the fixed mold assembly 1, the movable mold assembly 2 and the mold core fixing mechanism 3, the plastic mother liquid can be injection molded into a finished workpiece; The fixed mold assembly 1 includes a fixed seat plate 101, which is used to fix and support the I-type plate 102. The right side of the fixed seat plate 101 is fixedly connected to the I-type plate 102, and the I-type plate 102 is used to fix the guide column 103 and the return spring disk 104. The four corners of the right side of the I-type plate 102 are fixedly connected with guide columns 103. The guide columns 103 are used to fix and support the fixed mold frame 105 and enable the support plate 106 to slide on its outer wall. The right center of the I-type plate 102 is fixedly connected with a return spring disk 104. The return spring disk 104 is used to squeeze the cross bar 107 support plate 106 and reset the support plate 106 after it slides to the left so that it can be re-attached to the left side of the fixed mold frame 105. The right sides of multiple guide columns 103 are connected to the fixed mold by bolts. Frame 105, the fixed die frame 105 is used to clamp the punch core 301 and the clamping frame 302, and the outer wall of multiple guide columns 103 is slidably connected to a support plate 106 on the right side. The support plate 106 is used to fix and support the cross bar 107. The right side of the support plate 106 is equidistantly fixed with multiple cross bars 107 in a rectangular array. The cross bar 107 is used to support the top plate 108. The right side of each cross bar 107 is threadedly connected to a top plate 108. The top plate 108 is used to eject and demould the cooled and formed injection molded workpiece. The fixed die assembly 1 and the movable die assembly 2 are symmetrically arranged on the same horizontal line. The left side of the support plate 106 is pressed on the right side of the return spring disk 104, and the right side of the support plate 106 is attached to the left side of the fixed die frame 105. Multiple cross bars 107 pass through the interior of the fixed die frame 105.

[0023] In this embodiment, preferably, flange grooves are provided on the right outer side of the fixed mold frame 105 and the left outer side of the movable mold frame 206. The flange grooves are used to clamp the clamping frame 1 302 and the clamping frame 2 304. Square through holes that match their outer contours are provided at positions corresponding to the multiple insertion rods 210 on the right side of the fixed mold frame 105. After the fixed mold assembly 1 and the movable mold assembly 2 are molded, the insertion rods 210 will pass through the inside of the square through holes, thereby squeezing the support plate 106, thereby driving the top plate 108 to shrink to the right inner side of the punch core 301 through the support plate 106 and the cross bar 107. When the fixed mold assembly 1 and the movable mold assembly 2 are separated, the insertion rods 210 will cancel the support plate 1. 06 is extruded, and the support plate 106 is reset by the rebound force generated by the deformation of the reset spring disk 104, so that the support plate 106 is re-attached to the left side of the fixed mold frame 105, and then the top plate 108 can be ejected from the inside of the punch core 301. At the same time, the top plate 108 is ejected from the inside of the punch core 301, the cooled and formed injection molded workpiece can be demoulded, and the right side of the fixed mold frame 105 is equidistantly processed with multiple groups of clamping blocks in a rectangular array, which are used to clamp the punch core 301, so that a single punch core 301 can be preliminarily fixed, which is convenient for the subsequent fixation of the punch core 301 by the clamping frame 302, and the punch core 301 is convenient for replacement.

[0024] In summary, when assembling the fixed mold assembly 1, first connect the I-type plate 102 to the right side of the fixed seat plate 101 through bolt threads. After fixing the I-type plate 102, first sleeve the support plate 106 onto the outer wall of the guide column 103 fixed to the four corners on the right side of the I-type plate 102, and then connect the fixed mold frame 105 to the guide column 103 through bolts. Before the fixed mold frame 105 and the guide column 103 are put together, the multiple cross bars 107 on the right side of the support plate 106 will pass through the inside of the fixed mold frame 105, and then the punch core 301 in the mold core fixing mechanism 3 is clamped to the right side of the fixed mold frame 105 in turn, so as to fix the punch core 301 with coarse cloth and clamp it. After the punch core 301 is fixed, the clamping frame 1 302 is clamped to the inside of the flange groove opened on the right side of the fixed mold frame 105, and it is screwed together with the fixed mold frame 105 by bolts. Finally, the top plate 108 is screwed to the right side of the outer wall of the cross bar 107 to complete the assembly of the fixed mold assembly 1 and the punch core 301. When it is necessary to replace the punch core 301 of different specifications, the clamping frame 1 302 is removed from the right side of the fixed mold frame 105, and the snap connection of the clamping frame 1 302 to the punch core 301 is cancelled. Then the punch core 301 that needs to be replaced can be replaced, which is convenient for installation and disassembly of the punch core 301. In the mold closing stage, the fixed mold assembly 1 and the movable mold assembly The mold assembly 2 is closed along the same horizontal line. At this time, the insertion rod 210 in the movable mold assembly 2 will align with the square through hole on the fixed mold frame 105 and pass through it, directly squeezing the support plate 106 located on the outer wall of the guide column 103. After being squeezed, the support plate 106 slides to the left along the guide column 103, while compressing the return spring disk 104 in the center of the I-type plate 102. As the support plate 106 moves, the cross bar 107 connected to it drives the top plate 108 to shrink to the left synchronously, and finally the top plate 108 is stored in the right side of the punch core 301 to avoid interfering with the workpiece molding during the injection molding process. In the mold separation stage, the fixed mold assembly 1 is separated from the movable mold assembly 2, and the insertion rod 210 is withdrawn with the movable mold assembly 2. The squeezing of the support plate 106 is cancelled, and the compressed return spring disk 104 releases the rebound force, pushing the support plate 106 to slide to the right along the guide column 103 until it is re-adhered to the left side of the fixed mold frame 105. When the support plate 106 is reset, it will drive the cross bar 107 and the top plate 108 to move to the right synchronously, and the top plate 108 will be ejected from the inside of the punch core 301, and the cooled and formed injection molded workpiece will be ejected from the right side of the punch core 301 to realize the demoulding operation. During the whole process, the fixed seat plate 101, the I-plate 102, the guide column 103 and other components always provide stable support and guidance to ensure that the movement of each moving component is precise and controllable, thereby efficiently completing the injection molding and demoulding cycle.

The outer sides of the plurality of convex mold cores 301 are buckled with a clamping frame 1 302, and the clamping frame 1 302 is clamped inside the flange groove opened on the outer side of the right side of the fixed mold frame 105, and is fastened to the right side of the fixed mold frame 105 by bolts.

The right side of the second clamping frame 304 is clamped to the inside of the flange groove opened on the left side of the movable mold frame 206 and is also fastened to the left side of the movable mold frame 206 by bolts. The top plate 108 can be embedded in the right side of the male mold core 301, and the inner expansion sleeve 2037 extends through the inner center of the female mold core 303.

[0034] For example 4, please refer to Figures 1-15As shown, the present embodiment is obtained by combining the first, second and third embodiments. In terms of assembly, the mold core fixing mechanism 3, the fixed mold assembly 1 and the movable mold assembly 2 are installed and matched more tightly. The multiple punch cores 301 are firmly clamped to the right side of the fixed mold frame 105 through the clamping block. The first clamping frame 302 further strengthens the connection between the punch core 301 and the fixed mold frame 105, ensuring that the punch core 301 will not shift during the injection molding process.

Since the inner walls of the second-level hot nozzle 2035 and the diverter plate 2034 are coated with a high-temperature resistant modified super-hydrophobic coating, the residual adhesion of the melt is greatly reduced. At the same time, the heating coil can accurately heat the injection molding mother liquid as needed. When the material or color of the injection molding mother liquid needs to be changed, the heating coil can heat the injection molding mother liquid in the second-level hot nozzle 2035 and the diverter plate 2034 to a temperature far higher than the decomposition temperature of the plastic, thereby achieving ablation cleaning. With the help of a small amount of washing material or compressed air, the cleaning work can be completed quickly, reducing downtime and waste of washing material. During the demoulding process, when the movable mold assembly 2 and the fixed mold assembly 1 are separated along the same horizontal line, the insertion rod 210 in the movable mold assembly 2 stops squeezing the support plate 106, and the return spring disk 104 releases its rebound force, pushing the support plate 106 to slide rightward along the guide column 103, driving the cross bar 107 and the top plate 108 to move rightward synchronously, and the top plate 108 is ejected from the inside of the punch core 301, and the cooled and formed injection molded workpiece is smoothly ejected from the right side of the punch core 301, making the entire demoulding process smoother; In addition, the cooperation between the wire management groove and the buckle 20210 on the right side of the installation slot plate 2021 effectively avoids the confusion and displacement of the wiring harness, ensuring the stability of the electrical connection of the hot runner assembly 203. At the same time, the coordinated work of the support bar 2026, the spring telescopic rod 2029 and the buckle 20210 in the fixed component 202 further improves the reliability of the wiring harness fixation. The entire hot runner mold realizes efficient injection molding and demolding cycles through the close cooperation and coordinated work of various components, thereby improving production efficiency.
