Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example

[0026] See also Figure 1-5 The utility model is a hot runner mold for producing an e-sports keyboard, comprising a mold body 1, wherein the mold body 1 comprises: a lower mold base 11; a movable mold plate 12, which is arranged on the upper side of the lower mold base 11 and has a mold core 115 embedded therein; a fixed mold plate 13, which is relatively arranged on the upper side of the movable mold plate 12; an upper sealing plate 14, which is arranged on the upper side of the fixed mold plate 13 and has a gate 15 embedded in the middle; a heating cavity plate 120, which is located inside the upper sealing plate 14 and is connected to the gate 15; a heating element 113, which is located inside the heating cavity plate 120 and is connected to a controller 16; a cooling system, which is provided with multiple types of cooling pipes 119, and the ends of the cooling pipes 119 are connected to the end caps 111.

[0027] Further explanations of the above structure are:

[0028] The lower mold base 11 has a built-in top plate 17, and a return pin 114 is movably provided at the corner of the top plate 17, and a spring 18 is sleeved on the outer side of the return pin 114; a top rod 19 is fixed to the upper side of the top plate 17, and the top rod 19 cooperates with the mold core 115; a guide column 110 is provided at the corner of the lower mold base 11, and the guide column 110 is penetrated at the corners of the movable mold plate 12, the fixed mold plate 13 and the upper sealing plate 14; the heating cavity plate 120 is provided with a diverter nozzle 112, and the diverter nozzle 112 cooperates with the hot runner 116 provided inside the mold core 115; a mold cavity 117 is provided inside the mold core 115, and a label cavity 118 is provided on the edge of the mold core 115.

[0029] Specifically, the lower mold base 11 is located at the bottom of the mold, providing basic support for the entire mold. The movable mold plate 12 is arranged on the lower mold base 11, and can open and close relative to the fixed mold plate 13. The fixed mold plate 13 is fixed and does not move, providing a stable upper structure for the mold. The cooperation of the two enables the mold to open and close, thereby completing the process of injection molding and removing the product. The upper sealing plate 14 is located on the fixed mold plate 13, embedded with a gate 15, and is a key component connecting the injection molding machine and the mold. The heating cavity plate 120 is located inside the upper sealing plate 14, connected to the gate 15, and is equipped with a heating element 113 inside, which is used to keep the plastic raw material in the hot runner 116 in a molten state during the injection molding process. The heating element 113 is a heat-generating element, and the temperature is controlled by the controller 16 to ensure that the temperature inside the mold meets the injection molding requirements. The cooling system is provided with multiple types of cooling pipes 119, which are used to quickly cool the product after the injection molding is completed, so as to facilitate removal;

[0030] The top plate 17, the return pin 114 and the spring 18 form an ejection mechanism, which is used to eject the molded product from the mold core 115 when the mold is opened and closed. The top plate 17 cooperates with the mold core 115 through the ejector rod 19. When the mold is opened and closed, the top plate 17 drives the ejector rod 19 to eject the product; the return pin 114 and the spring 18 are used to ensure that the top plate 17 can be smoothly reset. The guide column 110 is passed through the corners of the movable mold plate 12, the fixed mold plate 13 and the upper sealing plate 14 to ensure the stability of the mold during the opening and closing process and avoid component misalignment. The diverter nozzle 112 is used in conjunction with the heating cavity plate 120 to guide the molten plastic raw material from the gate 15 to the hot runner 116 inside the mold core 115; the mold core 115 is provided with a mold cavity 117 and a label cavity 118. The mold cavity 117 is the space for forming the e-sports keyboard product, and the label cavity 118 is used to place the product label or logo.

[0031] When in use, the molten plastic raw material is first injected from the injection molding machine through the gate 15 into the heating cavity plate 120, and then enters the hot runner 116 inside the mold core 115 through the diverter nozzle 112. At this time, the heating element 113 works under the control of the controller 16 to keep the plastic raw material in the hot runner 116 always in a molten state. Then, the mold is closed, and the movable mold plate 12 cooperates with the fixed mold plate 13 to press the molten plastic raw material into the mold cavity 117 to form the initial shape of the gaming keyboard.

[0032] After the injection molding is completed, the mold is opened and closed again, and the ejection mechanism ejects the molded product from the mold core 115 to complete the entire injection molding process. During the injection molding process, the cooling system can quickly cool the product through the cooling pipe 119 to remove the product faster.

[0033] The hot runner 116 mold can reduce the solidification time of the mold and accelerate the flow speed of the plastic material, thereby greatly improving production efficiency; due to the coordinated use of the heating element 113 and the cooling system, the temperature inside the mold can be ensured to be balanced, avoiding problems such as plastic shortening, deformation and bubbles caused by temperature differences, thereby improving product quality; compared with traditional molds, it reduces energy consumption and material waste, thereby reducing production costs.
