Description

Technical Field

[0001] This utility model belongs to the field of hot nozzle structure technology, and specifically relates to a hot nozzle structure applied to high-temperature materials. Background Technology

[0002] Hot runner molds are a commonly used type of plastic injection molding mold. In hot runner molds, hot nozzles are a commonly used mechanical component in the hot runner system.

[0003] A search revealed that Chinese patent application number CN202121009098.9 discloses a hot nozzle structure for high-temperature materials, comprising a hot nozzle body and a hot nozzle heater sleeved outside the hot nozzle body. A gate is provided at the lower end of the hot nozzle body, and a main channel connecting to the gate is provided along the axial direction of the hot nozzle body. A nozzle core is provided at the gate position, and a gate seal is provided outside the lower end of the hot nozzle body, enclosing the nozzle core. The lower end of the hot nozzle heater extends to abut against the periphery of the gate seal. By placing the nozzle core inside the gate, placing the gate seal around the hot nozzle body, and extending the lower end of the hot nozzle heater to enclose the gate seal, the overall temperature of the hot nozzle body can be greatly increased, as can the temperature at the connection point between the hot nozzle structure and the mold, ensuring the temperature at the gate and preventing cold glue formation.

[0004] However, the above-mentioned hot nozzle structure for high-temperature materials still has the following drawbacks:

[0005] The device heats the entire hot nozzle body through a hot nozzle heater and a gate valve, ensuring the temperature at the gate outlet and preventing cold glue formation. However, when the hot nozzle stops working, the hot nozzle heater also stops working, causing the hot nozzle body to cool down. This makes the material that is not flowing out of the hot nozzle easily cool down, which can easily lead to cold glue formation and affect the use of the hot nozzle. Therefore, we need to propose a hot nozzle structure for high-temperature materials to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a hot nozzle structure for high-temperature materials. Through the installation of an insulation component, the hot nozzle heater heats the hot nozzle body. Simultaneously, the contact between the hot nozzle heater and the first sealing block heats the heat-conducting medium within the first sealing block. Under the heat transfer effect of the heat-conducting medium, the heat-conducting medium within the second sealing block is also heated, thus heating the nozzle core. After the hot nozzle stops working, the heat-conducting medium in the first and second sealing blocks transfers the absorbed heat to the hot nozzle body, reducing the cooling rate of the hot nozzle body. This makes it less likely for the material inside the hot nozzle body to cool down, thereby preventing the formation of cold glue and ensuring the hot nozzle's usability, thus solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a hot nozzle structure for high-temperature materials, comprising a hot nozzle body, a nozzle core installed at the bottom of the hot nozzle body, a hot nozzle heater for heating the material inside the hot nozzle body sleeved on the outer wall of the hot nozzle body, a temperature controller installed on the hot nozzle heater, a heat insulation component for reducing the cooling rate of the hot nozzle body sleeved on the outer walls of the hot nozzle heater and the nozzle core, a flow guiding component for guiding high-temperature materials into the hot nozzle body installed at one end of the hot nozzle body, and a fixing component for fixing the hot nozzle body to the flow guiding component installed on the flow guiding component and the hot nozzle body;

The first sealing block is sleeved on the outside of the hot nozzle heater, and the second sealing block is sleeved on the outside of the nozzle core. The second sealing block is mounted on the first sealing block.

[0009] Furthermore, the first sealing block has a first cavity, and the second sealing block has a second cavity, with the first cavity and the second cavity being connected.

[0010] Furthermore, the flow guiding component includes a mounting base, a flow guiding groove is provided at the bottom of the mounting base, a flow guiding pipe is provided in the flow guiding groove, and a limiting block is installed at the bottom of the mounting base, the limiting block being a circular ring structure.

[0011] Furthermore, the fixing component includes a first mounting block, which is mounted on the bottom of the mounting base. The first mounting block has a circular structure and is disposed outside the limiting block.

[0012] Furthermore, multiple sets of guide grooves and slots are formed on the inner wall of the first mounting block. The multiple sets of guide grooves and slots are arranged in an alternating manner, and the multiple sets of guide grooves and slots are arranged equidistantly in a ring around the central axis of the first mounting block.

[0013] Furthermore, the fixing component also includes a fixing block, which is sleeved on the outside of the hot nozzle body. A second mounting block is installed on the fixing block, and the second mounting block and the first mounting block are used in conjunction.

[0014] Furthermore, a limiting groove is provided between the second mounting block and the hot nozzle body. The limiting groove and the limiting block are used in conjunction. A sealing gasket is installed at the end of the second mounting block away from the fixing block.

[0015] Furthermore, multiple sets of guide blocks and locking blocks are installed on the side wall of the second mounting block. The multiple sets of guide blocks and locking blocks are staggered and are equidistantly arranged in a ring around the central axis of the second mounting block. The guide blocks and guide grooves are used in conjunction, and the locking blocks and locking grooves are used in conjunction.

[0016] Furthermore, multiple sets of fixing grooves are provided on the side wall of the second mounting block, and springs are installed on the inner walls of the multiple sets of fixing grooves.

[0018] This invention utilizes a heat-insulating component. The hot nozzle heater heats the hot nozzle body, and simultaneously, the contact between the hot nozzle heater and the first sealing block heats the heat-conducting medium within the first sealing block. Under the heat transfer effect of the heat-conducting medium, the heat-conducting medium within the second sealing block is also heated, thus heating the nozzle core. After the hot nozzle stops working, the heat-conducting medium in the first and second sealing blocks transfers the absorbed heat to the hot nozzle body, reducing the cooling rate of the hot nozzle body.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Please see Figure 1-5 This utility model provides a technical solution: a hot nozzle structure applied to high-temperature materials. It includes a hot nozzle body 110, a nozzle core 120 mounted at the bottom of the hot nozzle body 110, a hot nozzle heater 130 sleeved on the outer wall of the hot nozzle body 110 for heating the material inside the hot nozzle body 110, a temperature controller 140 mounted on the hot nozzle heater 130, and a heat-insulating component sleeved on the outer walls of the hot nozzle heater 130 and the nozzle core 120 for reducing the cooling rate of the hot nozzle body 110. A flow-guiding component for guiding high-temperature materials into the hot nozzle body 110 is mounted at one end of the hot nozzle body 110, and a fixing component for fixing the hot nozzle body 110 to the flow-guiding component is mounted on the flow-guiding component and the hot nozzle body 110.

[0029] The heat preservation component includes a first sealing block 210 and a second sealing block 230. The first sealing block 210 is sleeved on the outside of the hot nozzle heater 130, and the second sealing block 230 is sleeved on the outside of the nozzle core 120. The second sealing block 230 is mounted on the first sealing block 210.

[0030] In use, the hot nozzle heater 130 heats the hot nozzle body 110. At the same time, the contact between the hot nozzle heater 130 and the first sealing block 210 heats the heat-conducting medium inside the first sealing block 210. Under the heat transfer effect of the heat-conducting medium, the heat-conducting medium inside the second sealing block 230 is heated, and the nozzle core 120 is heated. After the hot nozzle stops working, the heat-conducting medium inside the first sealing block 210 and the second sealing block 230 transfers the absorbed heat to the hot nozzle body 110, reducing the cooling rate of the hot nozzle body 110. This makes it less likely for the material inside the hot nozzle body to be cooled, thus preventing the formation of cold glue and not affecting the use of the hot nozzle.

[0031] The heat nozzle body 110 is made of nickel-based alloy, which has excellent high-temperature resistance and oxidation resistance, and can be used for a long time in environments up to 1000°C, ensuring the stability and durability of the heat nozzle structure.

[0032] The first sealing block 210 has a first cavity 220, and the second sealing block 230 has a second cavity 240, and the first cavity 220 and the second cavity 240 are connected.

[0033] By setting the first cavity 220 and the second cavity 240 for storing the heat-conducting medium, when the heat-conducting medium is heated by the hot nozzle heater 130, the heat generated on the surface of the hot nozzle heater 130 is transferred to the heat-conducting medium, the heat-conducting medium stores the heat, and at the same time the heat is transferred in the heat-conducting medium, so that the second sealing block 230 heats the nozzle core 120, making it less likely for the material in the nozzle core 120 to generate cold glue.

[0034] The flow guiding component includes a mounting base 310, a flow guiding groove 320 is provided at the bottom of the mounting base 310, a flow guiding pipe 330 is provided in the flow guiding groove 320, and a limiting block 340 is installed at the bottom of the mounting base 310. The limiting block 340 has a circular ring structure.

[0035] The guide pipe 330 is used to transfer the material into the hot nozzle body 110.

[0036] The fixing component includes a first mounting block 410, which is mounted on the bottom of the mounting base 310. The first mounting block 410 has a circular structure and is disposed outside the limiting block 340.

[0037] The inner wall of the first mounting block 410 has multiple sets of guide grooves 420 and slots 430. The multiple sets of guide grooves 420 and slots 430 are staggered and are arranged in a ring at equal intervals with the central axis of the first mounting block 410 as the center.

[0038] The fixing component also includes a fixing block 440, which is sleeved on the outside of the hot nozzle body 110. A second mounting block 450 is mounted on the fixing block 440, and the second mounting block 450 and the first mounting block 410 are used together.

[0039] By setting the second mounting block 450 and the first mounting block 410, the hot nozzle body 110 is mounted on the mounting base 310 and inserted into the guide groove 320, so that the guide pipe 330 is inserted into the hot nozzle body 110, thereby realizing the transfer and flow of materials.

[0040] A limiting groove 470 is provided between the second mounting block 450 and the hot nozzle body 110. The limiting groove 470 and the limiting block 340 are used together. A sealing gasket 460 is installed at the end of the second mounting block 450 away from the fixing block 440.

[0041] By setting a sealing gasket 460 to seal the hot nozzle body 110, it is ensured that high-temperature materials will not leak, while preventing outside air or cooling medium from seeping in.

[0042] Multiple sets of guide blocks 451 and locking blocks 455 are installed on the side wall of the second mounting block 450. The multiple sets of guide blocks 451 and locking blocks 455 are staggered and arranged in a ring with the central axis of the second mounting block 450 as the center. The guide blocks 451 and guide grooves 420 are used in conjunction, and the locking blocks 455 and locking grooves 430 are used in conjunction.

[0043] By setting guide block 451 and guide groove 420 to guide the second mounting block 450, the second mounting block 450 can be stably inserted into the first mounting block 410, and the first mounting block 410 and the second mounting block 450 are fixed by the action of locking block 455 and locking groove 430.

[0044] The second mounting block 450 has multiple sets of fixing grooves 452 on its side wall. Springs 453 are installed on the inner walls of the multiple sets of fixing grooves 452. A movable plate 454 is installed on one end of each set of springs 453. The multiple sets of movable plates 454 are slidably connected in the multiple sets of fixing grooves 452. The side of the multiple sets of movable plates 454 away from the springs 453 is respectively installed on multiple sets of locking blocks 455.

[0045] With the spring 453 in place, when the hot nozzle body 110 needs maintenance, pressing the locking block 455 causes the locking block 455 to press the moving plate 454, which in turn presses the spring 453, compressing the spring 453 and moving the locking block 455 into the fixing groove 452. This separates the locking block 455 from the groove 430, thereby releasing the restriction on the second mounting block 450 and facilitating the removal of the hot nozzle body 110 for maintenance or replacement.

[0046] Specifically, the internal electrical connection structure of the temperature controller 140 and the hot nozzle heater 130 is well known to those skilled in the art and will not be described in detail here. All electrical components appearing in this application are connected to an external power source during use.

[0047] The circuits, electrical components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The scope of protection of this utility model does not involve any improvement to the software.

[0048] The control method described in this application is automatic control via a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming, which is common knowledge in the field. Furthermore, since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0049] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
