Description

Technical Field

[0001] This application relates to the field of hot nozzle device technology, and more particularly to an intelligent hot nozzle device with temperature control function. Background Technology

[0002] Hot runner systems use heating to keep the raw materials in the runner and gate in a molten state. A hot runner system generally consists of several parts, including hot nozzles, manifolds, temperature control boxes, and accessories. Hot nozzles generally include two types: open hot nozzles and needle valve hot nozzles. Since the type of hot nozzle determines the type of hot runner system and the type of mold manufacturing, hot runner systems are often divided into open hot runner systems and needle valve hot runner systems. Regardless of the type of hot nozzle, it can only perform simple heating operations and lacks precise temperature control and adjustment capabilities. This makes it difficult to ensure stable melting and precise molding of materials when processing different materials or facing complex process requirements. Product defects caused by temperature fluctuations, such as uneven molding and rough surfaces, are prone to occur. Therefore, an intelligent hot nozzle device with temperature control and adjustment functions has been proposed.

[0003] However, existing hot nozzle devices need to reach a suitable and stable temperature before operation to ensure that the plastic melt can pass smoothly through the nozzle and be accurately injected into the mold cavity. However, existing hot nozzle preheating mechanisms often have problems such as low preheating efficiency and insufficient temperature control, which affect the molding quality and production efficiency of the product. Moreover, most hot nozzle devices lack an effective filtration mechanism, or only use a simple filter structure, which has limited filtration effect and is prone to clogging, requiring frequent filter replacement, affecting production efficiency, increasing production costs, and thus reducing the utilization efficiency of the hot nozzle device. Summary of the Invention

[0004] In view of the above problems, this application provides an intelligent hot nozzle device with temperature control function to solve the problem that existing hot nozzle devices need to reach a suitable and stable temperature before operation to ensure that the plastic melt can pass through the nozzle smoothly and be accurately injected into the mold cavity. However, existing hot nozzle preheating mechanisms often have problems such as low preheating efficiency and insufficient temperature control, which affect the molding quality and production efficiency of the product. Moreover, most hot nozzle devices lack an effective filtration mechanism, or only use a simple filter structure, which has limited filtration effect and is easy to clog, requiring frequent filter replacement, affecting production efficiency and increasing production costs.

[0005] This application provides an intelligent thermal nozzle device with temperature control adjustment function. The intelligent thermal nozzle device includes a flow divider plate, a solenoid valve fixedly connected to the upper surface of the flow divider plate, an intelligent temperature control device fixedly installed on the outer surface of the flow divider plate, an intelligent temperature control module internally disposed in the intelligent temperature control device, and a thermal nozzle device fixedly connected inside the flow divider plate. The thermal nozzle device internally disposed in a heating element and a temperature sensor. The intelligent temperature control module is electrically connected to the heating element and the temperature sensor. A filter mechanism is fixedly installed on the upper surface of the flow divider plate, and a preheating mechanism is sleeved on the outer surface of the thermal nozzle device.

[0006] In some embodiments, the filtration mechanism includes a filter housing fixedly mounted on the upper surface of a flow divider plate, a feed pipe fixedly connected to the top surface of the filter housing, and a filter plate slidably mounted inside the filter housing.

[0007] In some embodiments, a filter plate two is disposed below the filter plate one, and a filter plate three is disposed below the filter plate two. Both the filter plate two and the filter plate three are fixedly installed inside the filter box, and filter screens of different specifications are respectively installed on the surfaces of the filter plate one, the filter plate two and the filter plate three.

[0008] In some embodiments, the preheating mechanism includes a preheating sleeve fitted onto the outer surface of the hot nozzle device. The upper and lower surfaces of the preheating sleeve are provided with a heating plate one and a heating plate two, which are symmetrically arranged. Both the heating plate one and the heating plate two are fitted onto the outer surface of the hot nozzle device.

[0009] In some embodiments, a drive motor is fixedly installed at the bottom of the diverter plate, a gear one is fixedly installed at the output end of the drive motor, a gear two is meshed with the outer surface of the gear one, and the gear two is fixedly installed outside the preheating sleeve.

[0010] In some embodiments, positioning rings are fixedly connected to both the upper and lower ends of the inner cavity of the preheating sleeve, and the two positioning rings are rotatably connected to the lower surface of the first heating plate and the upper surface of the second heating plate. The inner wall surface of the preheating sleeve is provided with a heat insulation plate and a heat insulation plate.

[0011] In some embodiments, a heating element is provided between the first heat insulation plate and the second heat insulation plate. The heating element is located at the upper and lower ends of the first heat insulation plate and the second heat insulation plate, and a heating rod is fixedly connected to the surface of the heating element.

[0012] The above scheme utilizes a feed pipe to inject injection molding granules into the interior of the filter housing. The granules undergo layered filtration through filter plates one, two, and three. Because the three plates use different mesh sizes (pore diameters), multi-stage filtration is achieved, effectively filtering impurities of varying sizes. All three plates are slidably installed inside the filter housing, allowing for easy cleaning and improving subsequent filtration efficiency. Heat from heating plates one and two is introduced into the preheating sleeve, absorbed by the heat-absorbing components within the hot nozzle device. The drive motor then rotates gear one, which meshes with gear two, causing the preheating sleeve to rotate along the outer wall of the hot nozzle device. This ensures uniform heating of the hot nozzle device, achieving a preheating effect and improving the device's operating efficiency.

[0025] To facilitate understanding of the technical solutions in the embodiments of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0026] First, it should be noted that the hot nozzle device of this application embodiment can be applied to hot channel flow or other equipment, and this application does not limit it.

[0027] This application provides an intelligent thermal nozzle device with temperature control adjustment function. Figure 1 This is a perspective view of a thermal nozzle device in some embodiments of this application. Figure 2 This is a perspective view of the filtering mechanism in some embodiments of this application. For example... Figure 1 , Figure 2 As shown, the intelligent hot nozzle device with temperature control function includes a flow divider plate 1. A solenoid valve 2 is fixedly connected to the upper surface of the flow divider plate 1. An intelligent temperature control device 3 is fixedly installed on the outer surface of the flow divider plate 1. An intelligent temperature control module is installed inside the intelligent temperature control device 3. A hot nozzle device 4 is fixedly connected inside the flow divider plate 1. A heating element and a temperature sensor are installed inside the hot nozzle device 4. The intelligent temperature control module is electrically connected to the heating element and the temperature sensor. A filter mechanism 5 is fixedly installed on the upper surface of the flow divider plate 1. A filter mechanism 5 is installed on the outer surface of the hot nozzle device 4. The device is equipped with a preheating mechanism 6. The filtration mechanism 5 includes a filter box 51 fixedly installed on the upper surface of the diverter plate 1. A feed pipe 52 is fixedly connected to the top surface of the filter box 51. A filter plate 53 is slidably installed inside the filter box 51. A filter plate 54 is arranged below the filter plate 53. A filter plate 55 is arranged below the filter plate 54. Both the filter plate 54 and the filter plate 55 are fixedly installed inside the filter box 51. Filter screens of different specifications are installed on the surfaces of the filter plate 53, the filter plate 54 and the filter plate 55 respectively.

[0028] In the technical solution of this application embodiment, injection molding granules are injected into the interior of the filter box 51 using the feed pipe 52. The injection molding granules are filtered in layers through filter plate 1 53, filter plate 2 54 and filter plate 3 55. Since the filter screens on the surfaces of the three plates are of different sizes, i.e., different pore sizes, multi-stage filtration is formed, which can effectively filter impurity particles of different sizes. All three plates are slidably installed inside the filter box 51 and can be cleaned by pulling them out, which helps to improve the filtration effect of the next time and thus improves the utilization efficiency of the hot nozzle device.

[0029] According to other embodiments of this application, such as Figure 3 As shown, the preheating mechanism 6 includes a preheating sleeve 61 that is fitted onto the outer surface of the hot nozzle device 4. Heating plate 62 and heating plate 63 are provided on the upper and lower surfaces of the preheating sleeve 61. Heating plate 62 and heating plate 63 are arranged symmetrically. Heating plate 62 and heating plate 63 are both fitted onto the outer surface of the hot nozzle device 4. A drive motor 64 is fixedly installed at the bottom of the flow divider 1. Gear 65 is fixedly installed at the output end of the drive motor 64. Gear 66 is meshed with the outer surface of gear 65. Gear 66 is fixedly installed on the outside of the preheating sleeve 61.

[0030] In this embodiment, the heat from the heating plate 62 and the heating plate 63 is introduced into the preheating sleeve 61 and then absorbed by the heat-absorbing component in the hot nozzle device 4. The drive motor 64 drives the gear 65 to rotate, and the gear 65 meshes with the gear 66 to drive the preheating sleeve 61 to rotate along the outer wall surface of the hot nozzle device 4, so that the hot nozzle device 4 can be heated evenly.

[0031] According to other embodiments of this application, such as Figure 4 As shown, positioning rings 611 are fixedly connected to both the upper and lower ends of the inner cavity of the preheating sleeve 61. The two positioning rings 611 are rotatably connected to the lower surface of the first heating plate 62 and the upper surface of the second heating plate 63. The inner wall surface of the preheating sleeve 61 is provided with a heat insulation plate 612 and a heat insulation plate 613. A heating element 614 is provided between the heat insulation plate 612 and the heat insulation plate 613. The heating element 614 is located at the upper and lower ends of the heat insulation plate 612 and the heat insulation plate 613. A heating rod 615 is fixedly connected to the surface of the heating element 614.

[0032] In this embodiment, the positioning ring 611 is connected to the heating plate 62 and the heating plate 63 respectively for easy installation. The heat insulation plate 612 and the heat insulation plate 613 are used for heat insulation to prevent the temperature between the structures from being too high. The outer wall of the hot nozzle device 4 is heated by the cooperation between the heating plate 614 and the heating rod 615, so that it can quickly generate heat and achieve a preheating effect.

[0033] The working principle of this intelligent thermal nozzle device with temperature control function will be explained in detail below.

[0034] like Figure 1 As shown in Figure 4, firstly, injection molding granules are injected into the filter housing 51 through the feed pipe 52. The injection molding granules undergo layered filtration through filter plates 53, 54, and 55. Because the three plates use different mesh sizes (i.e., different pore sizes), multi-stage filtration is formed, effectively filtering impurities of different sizes. All three plates are slidably installed inside the filter housing 51, allowing for easy cleaning by pulling them out, thus improving the filtration effect in subsequent stages. Simultaneously, the positioning ring 611... The heating elements are connected to heating plate 62 and heating plate 63 respectively for easy installation. Insulation is achieved through heat insulation plates 612 and 613 to prevent excessive temperature differences between structures. The heating element 614 and heating rod 615 work together to heat the outer wall of the hot nozzle device 4, enabling rapid heat generation and preheating. A drive motor 64 drives gear 65 to rotate, and gears 65 and 66 mesh to drive the preheating sleeve 61 to rotate along the outer surface of the hot nozzle device 4, ensuring uniform heating. Furthermore, a flow divider 1 distributes heat to each hot nozzle device 4, and an intelligent temperature control device 3, in conjunction with a temperature sensor inside the hot nozzle device 4, provides real-time temperature regulation, thereby improving the device's working efficiency.
