Description

Technical Field

[0001] This application relates to the field of die casting machine technology, and in particular to a feeding and forming device for a die casting machine with a detachable integrated gooseneck structure. Background Technology

[0002] Die casting has become one of the core processing technologies because it can efficiently produce metal parts with complex shapes and high dimensional accuracy. The key equipment for realizing this process is the die casting machine. The core feature of the die casting machine is that it uses a high-pressure drive mechanism to quickly and stably inject molten metal into the cavity of a pre-shaped metal mold. After the molten metal cools and solidifies in the mold, the mold can be opened to obtain the required solid metal casting. It is widely used in the mass production of automotive parts, mechanical parts, and metal structures for plastic products.

[0003] In the relevant technology, the heating mechanism first heats the metal raw material in the furnace mechanism, melting it into liquid metal. Then, the traversing mechanism drives the forming mechanism to move towards the furnace mechanism. The forming mechanism integrates a metal mold for casting. The injection mechanism includes a gooseneck structure. The traversing mechanism drives the forming mechanism to move until the mold and the molten metal output end are in a suitable mating position. Finally, the injection mechanism uses a dedicated gooseneck structure to guide the molten metal smoothly from the furnace mechanism to the forming mechanism, ensuring the continuity of the liquid metal flow and the stability of the filling. The liquid metal in the furnace mechanism is injected into the mold cavity under high pressure, completing the injection process.

[0004] The gooseneck structure is usually fixedly connected to the machine plate via a gooseneck mounting shaft. Specifically, one end of the gooseneck mounting shaft is rigidly fixed to the machine plate, and the gooseneck structure is fixedly connected to the gooseneck mounting shaft. The machine plate and the gooseneck mounting shaft work together to provide stable support for the gooseneck structure to resist the reaction force generated by the high-pressure liquid metal during the injection process.

[0005] However, after long-term operation of high-speed die-casting machines, the gooseneck structure is prone to problems such as inner wall wear and local deformation due to continuous contact with high-temperature molten metal and high-pressure impact. It needs to be inspected, maintained or replaced regularly. When production needs change, such as changing to different specifications of molds to produce castings of different sizes, the gooseneck structure of the appropriate specifications needs to be replaced. However, the existing technology makes it difficult to quickly disassemble and replace the gooseneck structure, resulting in insufficient flexibility of the equipment to adapt to diverse production needs, increasing time costs and operational difficulty. Utility Model Content

[0006] To address the aforementioned issues, this application provides a die-casting machine feeding and forming device with a detachable integrated gooseneck structure.

[0007] The present application provides a die-casting machine feeding and forming device with a detachable integrated gooseneck structure, which adopts the following technical solution: it includes a machine plate, an injection mechanism, and a forming mechanism. The injection mechanism and the forming mechanism are both disposed at both ends of the machine plate. The forming mechanism is slidably disposed on the machine plate. The injection mechanism includes a gooseneck structure, which is integrally formed. The gooseneck structure is provided with a casting pipe that penetrates the machine plate. The gooseneck structure and the machine plate are detachably connected.

[0008] By adopting the above technical solution, the gooseneck structure and the machine plate are detachably connected, allowing for direct disassembly of the gooseneck structure, which greatly simplifies inspection, maintenance, and replacement operations. At the same time, it can quickly replace gooseneck structures with different inner diameters and injection angles, increasing the equipment's adaptability to diverse production needs and reducing time costs and operational difficulties. During die casting, after the forming mechanism slides to the preset position on the machine plate, the casting pipe immediately injects liquid metal into the forming mechanism under high pressure. Furthermore, the one-piece formed gooseneck structure can improve its resistance to thermal stress and mechanical strength, stably withstand high-pressure injection conditions, and extend the single-use cycle.

[0009] Preferably, the injection mechanism further includes a gooseneck mounting shaft, the gooseneck structure is provided with a connecting part, the gooseneck mounting shaft is fixed to the machine plate, the connecting part is provided with a mounting hole, the gooseneck mounting shaft is inserted into the mounting hole, and the gooseneck mounting shaft and the mounting hole are detachably connected.

[0010] By adopting the above technical solution, since the gooseneck mounting shaft and mounting hole are detachably connected, the gooseneck structure can be quickly removed from the machine board by disconnecting the mounting hole from the gooseneck mounting shaft. This simplifies the inspection, maintenance, and replacement process. In scenarios where different specifications of gooseneck structures need to be replaced, the original gooseneck structure only needs to be disassembled from the gooseneck mounting shaft, and then the new specification gooseneck structure with the matching mounting hole can be plugged into the gooseneck mounting shaft to complete the replacement. This improves the equipment's adaptability to diverse production needs and reduces the time cost and operational difficulty of production changeover.

[0011] Preferably, there are three gooseneck mounting shafts arranged in a triangle on the machine plate, and there are three connecting parts, each corresponding to one of the gooseneck mounting shafts.

[0012] By adopting the above technical solution, the three gooseneck mounting shafts are distributed in a triangle on the machine plate. The triangular distribution is the layout form with the best stability in mechanical structure. It can evenly distribute the high temperature molten metal thermal stress and high pressure jet reaction force that the gooseneck structure bears during high-speed die casting to the three gooseneck mounting shafts and the machine plate, ensuring the positional accuracy of the gooseneck structure and reducing defects such as uneven filling and material shortage caused by the deviation of the gooseneck structure.

[0013] Preferably, each of the gooseneck mounting shafts has a connecting block on its outer wall and a connecting groove on its inner wall, and the connecting block and the connecting groove are inserted into each other.

[0014] By adopting the above technical solution, in high-speed die casting operations, the gooseneck structure needs to withstand the radial impact force generated by the high-pressure molten metal jet and the thermal stress under high temperature environment. The plug-in fit between the connecting block and the connecting groove can form a dual constraint in both circumferential and radial directions, reducing the radial movement of the gooseneck structure relative to the gooseneck mounting axis, ensuring that the gooseneck structure always maintains the preset installation posture, reducing the docking deviation between the casting pipe and the forming mechanism caused by radial displacement, and thus reducing defects such as molten leakage, uneven injection, or incomplete filling of the mold cavity during the injection process.

[0015] Preferably, each of the gooseneck mounting shafts is provided with a limiting plate, the limiting plate being disposed on the outer wall of the gooseneck mounting shaft, and the limiting plate being disposed at one end of the connecting block near the machine plate.

[0016] By adopting the above technical solution, when the mounting hole and the gooseneck mounting shaft are inserted, since the limiting plate is set on the outer wall and at the end of the connecting block near the machine plate, the mounting hole and the gooseneck mounting shaft gradually cooperate axially until the side wall of the connecting part abuts against the side wall of the limiting plate. At this time, the insertion and cooperation stop, reducing interference and extrusion deformation between the gooseneck structure and the machine plate caused by excessive insertion. At the same time, the abutting action of the limiting plate provides a uniform axial positioning reference for each gooseneck mounting shaft assembly, ensuring that the insertion depth of each gooseneck mounting shaft and the connecting part is completely consistent with the final installation position when each gooseneck mounting shaft is assembled with the connecting part, thus ensuring the stable docking accuracy between the casting pipe and the forming mechanism.

[0017] Preferably, the injection mechanism further includes a locking nut, and the end of the gooseneck mounting shaft away from the machine plate is provided with a threaded portion, and the locking nut is threadedly engaged with the threaded portion.

[0018] By adopting the above technical solution, the locking nut can tightly lock the gooseneck structure onto the gooseneck mounting shaft through threaded engagement with the threaded part, forming a reliable axial limit and ensuring the stable docking accuracy between the casting pipe and the forming mechanism. At the same time, when inspecting, maintaining or replacing the gooseneck structure, the locking nut can be unscrewed to release the fixation, making the operation simple.

[0019] Preferably, the injection mechanism further includes a spring washer disposed between the locking nut and the connecting portion.

[0020] By adopting the above technical solution, the spring washer compensates for the micro-unevenness of the contact surface between the locking nut and the gooseneck structure through elastic deformation, ensuring that the locking nut is subjected to uniform force when tightened. At the same time, it can maintain a stable preload under high temperature conditions, reduce the loosening of the locking nut caused by thermal expansion differences, and thus ensure the stability of the gooseneck structure during the injection process.

[0021] Preferably, the injection mechanism further includes a cotter pin, the locking nut is provided with a relief groove, the threaded portion is provided with a relief hole, the cotter pin passes through the relief groove and the relief hole in sequence, and the tail of the cotter pin is pried open and rigidly abuts against the side wall of the locking nut.

[0022] By adopting the above technical solution, under long-term high-pressure injection, high-frequency vibration and alternating temperature conditions, although the locking nut achieves axial fixation of the gooseneck structure through threaded engagement, the continuous mechanical vibration and the stress generated by the thermal expansion and contraction of the metal parts can easily cause gaps in the threaded engagement between the locking nut and the threaded part, which in turn can cause the locking nut to reverse and loosen. However, after the cotter pin passes through the relief groove and the relief hole of the threaded part of the locking nut in sequence, the end of the cotter pin forms a rigid abutment with the locking nut, which can directly restrict the circumferential rotational freedom of the locking nut from the mechanical structure, ensuring that the locking nut always maintains a stable axial pressure and preload on the gooseneck structure. When it is necessary to repair or replace the gooseneck structure, only the cotter pin needs to be removed to tighten the locking nut normally. The operation process is simple and takes into account both the reliability of anti-reverse and the convenience of equipment operation and maintenance.

[0023] Preferably, it also includes a visual inspection device and a temperature control device, which are electrically connected to the molding mechanism.

[0024] By adopting the above technical solution, the vision inspection device can achieve linkage with the molding mechanism through electrical connection, and collect image data in real time of the injection progress, melt distribution uniformity, and presence of defects such as material shortage and bubbles inside the mold cavity. The detection signal is quickly transmitted to the molding mechanism control system. If an abnormality is detected, the injection pressure, speed and other parameters of the injection mechanism can be adjusted in time. The temperature control device can monitor the mold working temperature in real time through electrical connection with the molding mechanism. When the temperature exceeds the preset process range, the heating or heat preservation adjustment function can be automatically activated to maintain the mold temperature stable within the optimal range for the solidification of the molten metal. Since the limiting plate abuts against the connecting part, the insertion and cooperation of the connecting block and the connecting groove restricts the displacement of the gooseneck structure relative to the mounting axis, further ensuring the stability of the injection path. Under this premise, the vision inspection device and the temperature control device can achieve more precise functions based on the stable limiting of the mechanical structure through electrical connection with the molding mechanism.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The gooseneck structure is designed as a single piece and is equipped with a casting pipe that passes through the machine plate and connects to the molding mechanism. At the same time, the gooseneck structure and the machine plate are detachably connected, allowing the gooseneck structure to be disassembled directly, which greatly simplifies its inspection, maintenance and replacement operations. It can also quickly replace gooseneck structures with different inner diameters and spray angles, effectively improving the equipment's adaptability to diverse production needs, reducing time costs and operational difficulties. In addition, the single-piece molded gooseneck structure can enhance its resistance to thermal stress and mechanical strength, and extend the single service cycle. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0036] This application discloses a die-casting machine blanking and forming device with a detachable integrated gooseneck structure 21. (Refer to...) Figure 1 The system includes a machine plate, a furnace mechanism 4, a heating mechanism 5, an injection mechanism 2, and a forming mechanism 3. The injection mechanism 2 and the forming mechanism 3 are respectively located at both ends of the machine plate. The forming mechanism 3 can slide horizontally along the machine plate. The furnace mechanism 4 and the heating mechanism 5 are both fixed on the machine plate. The heating mechanism 5 surrounds the furnace mechanism 4 to achieve uniform heating. The injection mechanism 2 is located directly above the furnace mechanism 4. The injection mechanism 2 includes a gooseneck structure 21. The injection mechanism 2 is connected to the furnace mechanism 4 through the gooseneck structure 21. The forming mechanism 3 can be moved on the machine plate to be aligned with or away from the furnace mechanism 4. The heating mechanism 5 first melts the metal raw material. The forming mechanism 3 moves on the machine plate to be close to the furnace mechanism 4. The injection mechanism 2 then injects liquid metal into the forming mechanism 3 under high pressure. After the casting is formed, it is reset. This is existing technology and will not be described in detail here.

[0037] Furthermore, the injection mechanism 2 also includes an injection cylinder 26, which is fixed to the gooseneck structure 21. The piston rod of the injection cylinder 26 is linked with the molten metal channel inside the gooseneck structure 21. The piston rod of the injection cylinder 26 presses down to transport the molten metal, injecting the molten metal in the furnace mechanism 4 into the forming device mechanism at high speed through the gooseneck structure 21, ensuring uniform filling of the molten metal. After the injection is completed, the piston rod of the injection cylinder 26 automatically resets to prepare for the next round of injection, realizing continuous and efficient production. This is existing technology and will not be described in detail here.

[0038] Reference Figure 2 , Figure 3 as well as Figure 4 Specifically, the gooseneck structure 21 is a one-piece molded design. The one-piece molded gooseneck structure 21 can improve its resistance to thermal stress and mechanical strength, and extend its single service cycle. The gooseneck mechanism and the machine plate are detachably connected, and the gooseneck structure 21 can be directly disassembled, which greatly simplifies the inspection, maintenance and replacement operations. At the same time, it can quickly replace the gooseneck structure 21 with different inner diameters and spray angles, which increases the equipment's adaptability to diverse production needs.

[0039] Furthermore, the gooseneck structure 21 is provided with a casting pipe 211, which passes through the machine plate and connects to the molding mechanism 3. At the same time, the injection mechanism 2 also includes a gooseneck mounting shaft 22. The gooseneck structure 21 is provided with a connecting part 212, and the gooseneck mounting shaft 22 is fixed to the machine plate. The connecting part 212 is provided with a mounting hole 2121, and the gooseneck mounting shaft 22 is inserted into the mounting hole 2121. The gooseneck mounting shaft 22 and the mounting hole 2121 are detachably connected. The mounting hole 2121 is adapted to the outer diameter of the gooseneck mounting shaft 22 to ensure the insertion fit. The insertion fit between the gooseneck mounting shaft 22 and the mounting hole 2121 is simple and reliable, and is easy to install and disassemble.

[0040] Furthermore, three gooseneck mounting shafts 22 are provided, and the three gooseneck mounting shafts 22 are distributed in a triangle on the machine plate. Three connecting parts 212 are provided, and the three connecting parts 212 correspond one-to-one with the gooseneck mounting shafts 22. The triangular distribution is the layout form with the best stability in mechanical structure. It can evenly distribute the high temperature molten metal thermal stress and high pressure jet reaction force borne by the gooseneck structure 21 during high-speed die casting to the three gooseneck mounting shafts 22 and the machine plate, ensuring the positional accuracy of the gooseneck structure 21 and reducing defects such as uneven filling and material shortage caused by the offset of the gooseneck structure 21.

[0041] Reference Figure 5 and Figure 6 Furthermore, each gooseneck mounting shaft 22 is provided with a limiting plate 222 and a connecting block 223. Both the connecting block 223 and the limiting plate 222 are fixed to the outer wall of the gooseneck mounting shaft 22. The inner wall of the mounting hole 2121 is provided with a connecting groove 2122. The connecting block 223 and the connecting groove 2122 are inserted into each other. The shape of the connecting block 223 is trapezoidal, and the shape of the connecting groove 2122 corresponds to that of the connecting block 223. The two inclined surfaces of the trapezoidal shape are subjected to the pressure generated by the jet of molten metal. When subjected to radial impact, the radial force acting on the inclined surface is converted into a normal pressure on the contact surface between the inclined surface perpendicular to the connecting block 223 and the inner wall of the connecting groove 2122, increasing the friction between the connecting block 223 and the connecting groove 2122, which can more effectively resist radial movement and strengthen the circumferential and radial constraints on the gooseneck structure 21. At the same time, the length of the connecting block 223 extends to the limiting plate 222 and is fixedly connected to the limiting plate 222. The limiting plate 222 is located at the end of the connecting block 223 near the machine plate.

[0042] This demonstrates that during high-speed die casting, the gooseneck structure 21 must withstand the radial impact force generated by the high-pressure molten metal jet and the thermal stress under high-temperature conditions. The insertion and engagement of the connecting block 223 and the connecting groove 2122 can form a dual constraint in both the circumferential and radial directions, effectively reducing the radial movement of the gooseneck structure 21 relative to the gooseneck mounting shaft 22. This ensures that the gooseneck structure 21 always maintains the preset installation posture, thereby reducing the deviation between the casting pipe 211 and the forming mechanism 3 caused by radial displacement, and reducing the occurrence of defects such as molten metal leakage, uneven injection, or incomplete filling of the mold cavity during the injection process.

[0043] Meanwhile, when the mounting hole 2121 and the gooseneck mounting shaft 22 are inserted and assembled, since the limiting plate 222 is located on the outer wall of the gooseneck mounting shaft 22 and at the end of the connecting block 223 near the machine plate, the mounting hole 2121 and the gooseneck mounting shaft 22 gradually cooperate along the axial direction until the side wall of the connecting part 212 abuts against the side wall of the limiting plate 222 and the insertion stops. This reduces the situation of interference and extrusion deformation between the gooseneck structure 21 and the machine plate due to excessive insertion. Furthermore, the abutting action of the limiting plate 222 provides a unified axial positioning reference for the assembly of each gooseneck mounting shaft 22, ensuring that the insertion depth and final installation position of each gooseneck mounting shaft 22 and the connecting part 212 are completely consistent, further ensuring the stability of the docking accuracy between the casting pipe 211 and the forming mechanism 3.

[0044] Reference Figure 7 and Figure 8 Furthermore, the injection mechanism 2 also includes locking nuts 23, of which three are provided, one for each gooseneck mounting shaft 22. The end of the gooseneck mounting shaft 22 away from the machine plate is provided with a threaded part 221, and the locking nuts 23 are threadedly engaged with the threaded part 221. The function of the locking nuts 23 is to firmly fix the gooseneck structure 21 onto the gooseneck mounting shaft 22. The locking nuts 23 are hexagonal slotted nuts, and the hexagonal slotted nuts are provided with a relief groove 231. The injection mechanism 2 also includes a cotter pin 24, and the threaded part 221 is provided with a relief hole 2211. The cotter pin 24 passes through the relief groove 231 and the relief hole 2211 in sequence, and the cotter pin 24 abuts against the locking nuts 23.

[0045] Specifically, the cotter pin 24 is a fastener made of metal wire, with an overall hairpin-like structure. It mainly consists of a pin body 241 and two pryable tails 242. The pin body 241 is circular, and the two pryable tails 242 pass through the relief groove 231 and the relief hole 2211 in sequence. After passing through the relief groove 231 and the relief hole 2211, the two pryable tails 242 can be pried open outwards. The two pryable tails 242 abut against the side wall of the locking nut 23. The pin body 241 abuts against the side wall of the locking nut 23 to form an anti-disengagement jamming structure, thereby realizing the abutment between the cotter pin 24 and the locking nut 23, and using the toughness and strength of the metal wire to maintain a stable locking state.

[0046] This explains that under long-term conditions of high-pressure injection, high-frequency vibration, and alternating temperature changes, although the locking nut 23 achieves axial fixation of the gooseneck structure 21 through threaded engagement, the continuous mechanical vibration and the stress generated by the thermal expansion and contraction of the metal parts can easily cause gaps in the threaded engagement between the locking nut 23 and the threaded part 221, leading to the locking nut 23 reversing and loosening. The cotter pin 24 passes through the relief groove 231 of the locking nut 23 and the relief hole 2211 of the threaded part 221 in sequence, forming a rigid abutment with the locking nut 23. This can directly restrict the circumferential rotational freedom of the locking nut 23 from a mechanical structure perspective, ensuring that the locking nut 23 always maintains a stable axial pressure and preload on the gooseneck structure 21. When it is necessary to repair or replace the gooseneck structure 21, only the cotter pin 24 needs to be removed to tighten the locking nut 23 normally. The operation process is simple, taking into account both the reliability of anti-reversal and the convenience of equipment operation and maintenance.

[0047] Meanwhile, the injection mechanism 2 also includes a spring washer 25, which is disposed between the locking nut 23 and the connecting part 212. The spring washer 25 is an elastic mechanical fastener, a ring washer made of spring steel, which has a certain elastic deformation capability. When it is pressed by the locking nut 23, it generates a continuous rebound force through its own elastic deformation. On the one hand, it compensates for the micro-unevenness of the contact surface between the locking nut 23 and the gooseneck structure 21, so that the locking nut 23 is subjected to uniform force when tightened. On the other hand, it can maintain a stable preload under high temperature, vibration and other working conditions, and offset the gap caused by thermal expansion difference and mechanical vibration, thereby effectively reducing the risk of the locking nut 23 loosening and ensuring the installation stability of the gooseneck structure 21 during the injection process.

[0048] Furthermore, this embodiment also includes a vision inspection device 6 and a temperature control device 7. The vision inspection device 6 and the temperature control device 7 are electrically connected to the molding mechanism 3. The vision inspection device 6 can achieve linkage through its electrical connection with the molding mechanism 3, real-time acquisition of image data on the injection progress inside the mold cavity, the uniformity of melt distribution, and the presence of defects such as material shortages and bubbles. It quickly transmits the detection signals to the control system of the molding mechanism 3. If an abnormality is detected, it can promptly provide feedback to adjust parameters such as the injection pressure and speed of the injection mechanism 2. The electrical connection between the temperature control device 7 and the molding mechanism 3 enables… The system monitors the working temperature of the mold in real time. When the temperature exceeds the preset process range, it can automatically start the heating or heat preservation adjustment function to maintain the mold temperature stable within the optimal range for the solidification of the molten metal. Since the limiting plate 222 abuts against the connecting part 212 and the connecting block 223 and the connecting groove 2122 are engaged, the displacement of the gooseneck structure 21 relative to the mounting shaft is restricted, further ensuring the stability of the injection path. Under this premise, the vision inspection device 6 and the temperature control device 7 are electrically connected to the molding mechanism 3, and can achieve the function more accurately based on the stable positioning of the mechanical structure.

[0049] The implementation principle of the die-casting machine forming device with a detachable integrated gooseneck structure 21 in this application embodiment is as follows: First, the heating mechanism 5 fixed on the machine plate runs around the furnace mechanism 4 to uniformly heat the metal raw material in the furnace mechanism 4 until the metal melts into a liquid state, providing qualified raw material for the die-casting operation. At the same time, the forming mechanism 3 slides horizontally along the machine plate and is driven to a position aligned with the furnace mechanism 4 to complete the docking preparation before die-casting.

[0050] The injection mechanism 2 serves as the core of the injection process. The gooseneck structure 21 connects to the furnace mechanism 4 to receive the molten metal. Three triangularly distributed gooseneck mounting shafts 22 are fixed to the machine plate and precisely inserted into the mounting holes 2121 of the connecting part 212 of the gooseneck structure 21. The connecting block 223 mates with the connecting groove 2122 of the corresponding mounting hole 2121. The limiting plate 222 abuts against the side wall of the connecting part 212 during the insertion process to ensure that the casting pipe 211 and the forming mechanism 3 have consistent docking accuracy. Assembly is complete. The rear locking nut 23 axially fixes the gooseneck structure 21 by threading with the threaded part 221. The cotter pin 24 passes through the relief groove 231 and the relief hole 2211 and is pried open at the tail 242 to form a mechanical anti-loosening mechanism to reduce the reverse rotation of the locking nut 23 caused by vibration or thermal stress. The spring washer 25 between the locking nut 23 and the connecting part 212 compensates for the micro-unevenness of the contact surface through elastic deformation, maintains a stable preload, and further ensures the installation stability of the gooseneck structure 21 under high pressure and high temperature conditions.

[0051] Subsequently, the injection mechanism 2 is activated, and the piston rod of the injection cylinder 26 is pressed down, injecting the liquid metal in the furnace mechanism 4 into the forming mechanism 3 in a high-pressure form through the casting pipe 211 of the gooseneck structure 21. During this process, the vision inspection device 6 is electrically linked with the forming mechanism 3 to collect the injection progress, melt distribution and defects in the mold in real time. The temperature control device 7 monitors and adjusts the mold temperature simultaneously to ensure that the temperature is within the optimal range for metal solidification. Based on the precise positioning and stable assembly of the gooseneck structure 21, the vision inspection device 6 and the temperature control device 7 can quickly provide feedback and adjust the injection parameters to reduce melt leakage, uneven injection or casting deformation. After the casting is formed, the forming mechanism 3 slides horizontally along the machine plate to reset, completing a single die casting cycle.

[0052] When maintenance or adaptation to the production of castings of different specifications is required, the gooseneck structure 21 can be disassembled from the gooseneck mounting shaft 22 simply by removing the cotter pin 24 and unscrewing the locking nut 23. The one-piece molded gooseneck structure 21 with different inner diameters or spray angles can be replaced, which greatly simplifies the operation, reduces time costs, and enables the equipment to be flexibly adapted to diverse production needs.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
