Description
A quick-change device for die-cast contour spray heads Technical Field
[0001] This utility model relates to the field of die-casting contour spraying technology, specifically to a quick switching device for a die-casting contour spraying head. Background Technology
[0002] During die casting, the mold cavity surface is subjected to high pressure, high speed, and high temperature from the molten metal, resulting in a strong tendency for adhesion. Therefore, a release agent is sprayed onto the cavity surface to form a thin film that isolates it from the molten metal. The main functions of the release agent are: to ensure smooth molten metal filling, facilitating molding, preventing sticking and welding, and resulting in a bright, smooth, and flat surface finish on the casting; to protect the mold from the scouring effect of the high-temperature molten metal, reducing the mold's thermal conductivity and temperature, and extending its lifespan; and to facilitate smooth demolding of the casting during mold opening.
[0003] A search revealed existing technology (publication number: CN113976372A), which describes "an integrated panel spraying system, including a handle, a water-air grouping plate, and a water-air integrated plate; the water-air grouping plate is connected to water-air integrated plates on both sides; the water-air grouping plate is provided with several sets of control spray gun shut-off air pipes, release agent injection pipes, and control spray gun open air pipes; several rows of spray guns and several rows of air nozzles are arranged in an array outside the water-air integrated plate; each set of spray gun shut-off air pipes, release agent injection pipes, and control spray gun open air pipes are connected to the corresponding pipelines in the water-air integrated plate through the water-air grouping plate; each row of spray guns in the water-air integrated plate is connected through the same pipeline; the water-air grouping plate is also provided with at least one air inlet pipe, which can be simultaneously connected to each air nozzle through the water-air grouping plate and the pipelines in the water-air integrated plate. This invention uses integrated branch pipelines to replace a large number of flexible hoses, and adopts a modular design of the spray head, reducing the spray movement trajectory and improving spraying quality and efficiency."
[0004] Although the integrated panel spraying system described in the aforementioned patent documents achieves a modular design for the spray head, the frequent switching of spray heads is caused by the need for frequent product switching in current die-casting production. Traditional switching methods require disassembling a large number of water pipes, atomizing air pipes, and control air pipes, which is labor-intensive, prone to errors during disassembly and assembly, and wastes a lot of time. Summary of the Invention
[0005] To overcome the shortcomings of the existing technology, a quick switching device for die-cast contour spraying head is provided to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, a quick switching device for a die-cast contour spray head is provided, comprising: an integrated plate, wherein the upper end of the integrated plate is provided with a fixing hole and a guide hole, and the front and rear ends of the integrated plate are provided with mounting notches, and the left and right ends of the integrated plate are provided with insertion holes and guide grooves. The mounting notches are provided with protrusions at both ends, and through holes are provided inside the protrusions. Guide notches are provided at the four corners of the integrated plate. An outer sliding plate, including a fixing component, is slidably connected to the outer wall of the mounting notch. A motor is mounted on the outer side of the outer sliding plate via a mounting plate. The output shaft of the motor is connected to a rotating shaft, and the outer end of the rotating shaft is connected to a threaded rod. A moving mold spray plate and a fixed mold spray plate are respectively connected to both ends of the integrated plate. Connecting blocks and insertion pipes are provided on the inner sides of the moving mold spray plate and the fixed mold spray plate, and guide blocks are provided on the inner sides of the connecting blocks.
[0007] Furthermore, the outer wall of the mounting notch is provided with a sliding groove, and the inner slider connected to the inner side of the outer sliding plate is slidably connected to the sliding groove.
[0008] Furthermore, the insertion tube is matched and inserted into the insertion hole, and the insertion tube communicates with the internal cavity opened inside the plate body included in the moving mold spray plate.
[0009] Furthermore, the guide block is matched and inserted into the guide groove, and the connecting block is located in the guide notch at this time.
[0010] Furthermore, the connecting block has a threaded hole on the side facing the protrusion, and the threaded hole corresponds to the position of the through hole, and the threaded rod is screwed into the threaded hole.
[0011] Furthermore, a hydraulic cylinder is horizontally fixed in the middle of the mounting notch, and the piston rod end of the hydraulic cylinder is fixedly connected to the outer sliding plate.
[0012] Furthermore, nozzles are provided on the outer sides of the moving mold spray plate and the fixed mold spray plate, and the nozzles are in communication with the inner cavity.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. When it is necessary to replace the spray head, namely the moving mold spray plate and the fixed mold spray plate involved in this application, start the motor to rotate in reverse, so that the threaded rod is pulled out of the threaded hole. At this time, the hydraulic cylinder is in a depressurized state, which pushes the piston rod to reset. After the threaded rod is completely pulled out of the threaded hole, the spray plate can be removed from both ends of the integrated plate. Then, the spray plate with different nozzles can be replaced and installed. This allows for quick replacement of all nozzles, avoids errors in the disassembly and assembly process, and saves time.
[0015] 2. By integrating all nozzles together using a spray plate, it is possible to replace them all at once without disassembling a large number of water pipes, atomizing air pipes, and control air pipes. This improves the efficiency of switching spray heads when frequently changing products. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Referring to Figures 1 to 4, this utility model provides a quick switching device for a die-cast contour spray head, comprising: an integrated plate 1, wherein the upper end of the integrated plate 1 is provided with a fixing hole 11 and a guide hole 12, and the front and rear ends of the integrated plate 1 are provided with mounting notches 13, and the left and right ends of the integrated plate 1 are provided with insertion holes 16 and guide grooves 17, the two ends of the mounting notches 13 are provided with protrusions 14, and the protrusions 14 are provided with through holes 15, and guide notches are provided at the four corners of the integrated plate 1. 18. The outer wall of the mounting notch 13 is slidably connected to the outer slide plate 43 included in the fixing component 4, and the outer slide plate 43 is mounted with a motor 41 through the mounting plate 42. The output shaft end of the motor 41 is connected to a rotating shaft 45, and the outer end of the rotating shaft 45 is connected to a threaded rod 46. The two ends of the integrated plate 1 are respectively connected to a moving mold spray plate 2 and a fixed mold spray plate 5, and the inner ends of the moving mold spray plate 2 and the fixed mold spray plate 5 are provided with a connecting block 24 and a plug pipe 27, and the inner side of the connecting block 24 is provided with a guide block 26.
[0023] In this embodiment, the integrated plate 1 and the fixing component 4 constitute the main structure of the quick switching device for the die-cast contour spray head involved in this application.
[0024] The integrated plate 1 has a cavity inside and is connected to the upper spray liquid delivery pipe through the guide hole 12, so that the spray liquid can be delivered into the integrated plate 1 and then delivered to the spray plates on both sides through the insertion hole 16.
[0025] The integrated plate 1 is connected to the robot execution end on the outside through the fixing hole 11, which enables the entire spraying device to move.
[0026] It should be noted that when the moving mold spray plate 2 and the fixed mold spray plate 5 are used, they are moved by a robotic arm to the space between the moving mold and the fixed mold included in the mold after the mold is opened. At this time, the side of the moving mold spray plate 2 with nozzle 23 faces the inside of the moving mold, and the side of the fixed mold spray plate 5 with nozzle 23 faces the inside of the fixed mold, so that the spraying liquid (specifically the release agent) is evenly sprayed on the molding cavity. In addition, for different die casting molds, since the die casting cavity of the mold is formed in different sizes, the spray plates are set to various specifications to match them. However, the position of the insertion pipe 27 on the inside of the spray plate remains unchanged, so that any spray plate can be easily connected to the insertion hole 16 on the outside of the integrated plate 1.
[0027] As shown in Figures 1 to 4, the outer wall of the mounting notch 13 is provided with a sliding groove 19, and the inner slider 44 connected to the inner side of the outer sliding plate 43 is slidably connected to the sliding groove 19. The insertion pipe 27 is matched and inserted into the insertion hole 16, and the insertion pipe 27 is connected to the inner cavity 22 opened inside the plate 21 included in the moving mold spray plate 2. The guide block 26 is matched and inserted into the guide groove 17, and the connecting block 24 is located in the guide notch 18. The connecting block 24 is provided with a threaded hole 25 on the side facing the protrusion 14, and the threaded hole 25 corresponds to the position of the through hole 15. The threaded rod 46 is matched and screwed into the threaded hole 25. A hydraulic cylinder 3 is horizontally fixed in the middle of the mounting notch 13, and the piston rod end of the hydraulic cylinder 3 is fixedly connected to the outer sliding plate 43. The outer side of the moving mold spray plate 2 and the fixed mold spray plate 5 is provided with a nozzle 23, and the nozzle 23 is connected to the inner cavity 22.
[0028] Specifically, when the connection is made, the hydraulic cylinder 3 pushes the threaded rod 46 into the through hole 15 and then into the threaded hole 25 through the outer slide plate 43. At this time, the hydraulic cylinder 3 achieves a pressure-holding state through the solenoid valve. At this time, the threaded rod 46 and the end of the threaded hole 25 maintain a certain pressure. At this time, the motor 41 is started to drive the threaded rod 46 to rotate, which realizes the connection with the threaded hole 25.
[0029] In use, when it is necessary to replace the spray head, namely the moving mold spray plate and the fixed mold spray plate involved in this application, the motor is started to rotate in reverse, causing the threaded rod to retract out of the threaded hole. At this time, the hydraulic cylinder is depressurized, which pushes the piston rod to reset until the threaded rod is completely retracted from the threaded hole. Then, the spray plate can be removed from both ends of the integrated plate. Then, the spray plate with different nozzles can be replaced and installed. This allows for quick replacement of all nozzles, avoiding errors in the disassembly and assembly process and saving time. By integrating all nozzles together with the spray plate, the entire nozzle can be replaced at once without disassembling a large number of water pipes, atomizing air pipes, and control air pipes. This improves the efficiency of switching spray heads when frequently switching products.
[0030] The quick switching device for die-cast contour spray heads of this utility model can effectively solve the problems mentioned in the background technology. Based on the existing quick switching device technology for die-cast contour spray heads, it can quickly replace all spray heads, improve replacement efficiency, and reduce the replacement error rate.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
