Abstract
Description
Technical Field
[0001] This utility model belongs to the field of die casting spraying technology, specifically relating to a spraying device for die casting molds. Background Technology
[0002] The application of release agent in die casting is a crucial step in the die casting process, playing a decisive role in the proper demolding of products and the control of mold temperature. Simultaneously, the application time is a significant component of the die casting production cycle. In optimizing the die casting production cycle for new products, shortening the application time can yield the most significant cycle optimization. It can be said that the length of the application time has a pivotal impact on the die casting production cycle. Under the condition of meeting production requirements, a shorter application time helps to shorten the die casting cycle and increase the output per unit time.
[0003] Currently, the application of release agents to molds is mostly done using robotic spraying. After the mold is opened and the part is removed, a robot carries a spraying box to perform the spraying process. Due to the limitations of the mold and spraying box structure, the robot often needs to move to multiple positions to achieve complete spraying of the mold surface. For complex, large molds, this process is extremely complex and time-consuming. To address this, specialized spraying boxes designed for specific product mold structures have emerged. Their nozzles directly correspond to various positions on the mold surface, allowing the robot to complete the spraying of the entire mold surface with simple action commands, significantly reducing spraying time. However, specialized spraying boxes are only suitable for single molds and cannot be applied to different molds in actual production. Utility Model Content
[0004] In view of one or more of the above-mentioned defects or improvement needs of the prior art, the present invention provides a spraying device for die casting molds, which can quickly switch between different molds.
[0005] To achieve the above objectives, this utility model provides a spraying device for die-casting molds, comprising: A spraying box, wherein a spraying device is installed inside the spraying box, and the outlet of the spraying device is located on the outer surface of the spraying box; Mounting plate, which is fixedly connected to the side of the spray box, and has several grooves.

The first externally threaded pagoda head is slidably connected in the slide groove, with its two ends located on both sides of the slide groove. The end facing the spray box is connected to the discharge port through a connecting pipe, and the end facing away from the spray box is a threaded end connected to the nozzle. The first externally threaded pagoda head can be locked on the mounting plate.
[0006] As a further improvement of this utility model, the mounting plate is provided with a plurality of sliding grooves, and the sliding grooves are arranged in parallel and spaced apart.
[0007] As a further improvement of this utility model, the connecting pipe is connected to the feed port of the nozzle through a second external threaded pagoda head.
[0008] As a further improvement of this utility model, it includes a sleeve and a spring.

One end of the spring abuts against the mounting plate, and the other end abuts against the shoulder of the first external thread pagoda head. The spring is in a compressed state, pressing the sleeve tightly against the mounting plate.
[0009] As a further improvement of this utility model, the mounting plate has a plurality of positioning holes on at least one side of the slide groove, and the positioning holes are spaced apart along the length direction of the slide groove; The sleeve is provided with a wing plate, and the wing plate is provided with a buckle that matches the shape and size of the positioning hole. When the sleeve is pressed against the mounting plate, the buckle can be engaged in the positioning hole.
[0010] As a further improvement of this utility model, the mounting plate is provided with a first code corresponding to each of the positioning holes.
[0011] As a further improvement of this utility model, the discharge port is provided on the side of the spray box connected to the mounting plate, and the side is provided with a plurality of discharge ports and a second code corresponding to each discharge port.
[0012] As a further improvement of this utility model, the discharge port, the mounting plate and the second code are provided on multiple sides of the spray box.
[0013] As a further improvement of this utility model, the mounting plate is fixedly connected to the spray box by multiple pillars.
[0014] As a further improvement of this utility model, a first pad and a second pad are also fitted on the first external thread pagoda head.

[0015] The aforementioned improved technical features can be combined with each other as long as they do not conflict with each other.
[0016] In summary, the beneficial effects of the above-described technical solutions conceived by this utility model compared with the prior art include: (1) The spraying device for die casting mold of this utility model includes a spraying box, a mounting plate, and a spray head. The surface of the spraying box is provided with the discharge port of the spraying equipment. The side of the spraying box is fixedly connected to the mounting plate. Several sliding grooves are opened on the mounting plate. The spray head includes a nozzle connected to it and a first external threaded pagoda head. The nozzle is located on the side away from the spraying box. The first external threaded pagoda head is slidably connected to the sliding groove and connected to the discharge port of the spraying box through a connecting pipe, so that the spray head can slide along the sliding groove of the mounting plate to any position and then be locked on the mounting plate, so that the spray head of this spraying device can quickly change position for the mold surface of different molds, so that this spraying device can be quickly transformed into a special spraying box for different product mold structures.
[0017] (2) The spraying device for die casting mold of this utility model limits the mounting plate and spring sleeved on the first external thread pagoda head by means of the sleeve and the shoulder of the first external thread pagoda head, so that the spring is always in a compressed state, pressing the sleeve on the mounting plate, that is, pressing the spray head on the mounting plate, so that the spray head can be moved along the slide groove to any position and can be stably connected with the mounting plate in the direction perpendicular to the slide groove.

[0028] Example: Please see Figures 1-4 The spraying device for die-casting molds in the preferred embodiment of this utility model includes a spraying box 1, a mounting plate 2, and a spray nozzle 3.
[0029] The spray box 1 is equipped with a spraying device, and the outlet 11 of the spraying device is located on the outer surface of the spray box 1. The mounting plate 2 is fixedly connected to the side of the spray box 1, and several sliding grooves 21 are provided on the mounting plate 2. The nozzle 3 includes a nozzle 31 and a first external threaded pagoda head 32. The first external threaded pagoda head 32 is slidably connected in the sliding groove 21, with its two ends located on both sides of the sliding groove 21. The end facing the spray box 1 is connected to the outlet 11 through a connecting pipe 4, and the end facing away from the spray box 1 is a threaded end, which is connected to the nozzle 31. The first external threaded pagoda head 32 can be locked on the mounting plate 2.
[0030] In this preferred embodiment, the nozzle 31 and the first external threaded pagoda head 32 are connected to form a channel for the paint to be fed through the nozzle 3. The spraying equipment inside the spraying box 1 includes a controller, atomizer, and various pipeline equipment required for the spraying robot. The nozzle 3 is mounted on the mounting plate 2 outside the spraying box 1 and connected to the discharge port 11 of the spraying box 1 through the connecting pipe 4, so that the nozzle 3 can slide to any position in the slide groove 21 of the mounting plate 2 and then lock onto the mounting plate 2. This allows the nozzle 3 of this spraying device to quickly change position for different mold surfaces, enabling this spraying device to quickly transform into a dedicated spraying box for different product mold structures.
[0031] Preferably, a sealing ring is provided between the nozzle 31 and the first external threaded pagoda head 32.
[0032] Preferably, the discharge port 11 is located on the side of the spray box 1 opposite to the mounting plate 2 to reduce the required length of the connecting pipe 4 and facilitate storage. Further, this side of the spray box 1 has multiple discharge ports 11 for connection to multiple nozzles 3 on the mounting plate 2, allowing multiple nozzles 3 to simultaneously spray different positions on the mold surface. More preferably, this side of the spray box 1 also has a second code corresponding one-to-one with the discharge ports 11, facilitating programming, identification, and process recording of the spraying robot. Furthermore, the multiple sides of the spray box 1 each have discharge ports 11, mounting plates 2, and second codes, enabling simultaneous spraying of multiple parts of the mold, saving spraying time.
[0033] In a specific preferred embodiment, such as Figure 2 As shown, the side of the spray box 1 has a dense array of discharge ports 11, which are coded and named in the form of coordinates. The discharge ports 11 are arranged in numbers along the extension direction of the slide groove 21 and in letters along the direction perpendicular to the slide groove 21.
[0034] Preferably, the mounting plate 2 is fixedly connected to the spray box 1 by multiple support columns 10. One end of each support column 10 is fixedly connected to the mounting plate 2, and the other end is fixedly connected to the spray box 1, thus separating the mounting plate 2 from the spray box 1 and reserving installation space for the connecting pipe 4. The support columns 10 are preferably arranged parallel to each other around the perimeter of the mounting plate 2.
[0035] Preferably, the groove 21 on the mounting plate 2 can be of any shape, such as straight, broken, wavy, etc., without specific limitations.
[0036] Preferably, the mounting plate 2 has multiple sliding grooves 21, which are arranged in parallel and spaced apart, allowing the nozzles 3 to slide to more positions on the mounting plate 2 to adapt to the spraying parts of different molds. In this preferred embodiment, each sliding groove 21 may contain zero or one or more nozzles 3, depending on the structure of the mold.
[0037] Preferably, the connecting pipe 4 is a flexible hose. Further, the connecting pipe 4 is connected to the outlet 11 of the spraying equipment via a second externally threaded pagoda head 7. In this embodiment, both ends of the connecting pipe 4 are connected to a first externally threaded pagoda head 32 and a second externally threaded pagoda head 7, respectively. A pagoda head is a fitting used for connecting and sealing pipes, possessing good sealing performance and high pressure resistance.
[0038] More preferably, the spraying device further includes a sleeve 5 and a spring 6. Both the sleeve 5 and the spring 6 are sleeved on the first external thread pagoda head 32 and located on both sides of the slide groove 21. The sleeve 5 is fixedly connected to the threaded end. One end of the spring 6 abuts against the mounting plate 2, and the other end abuts against the shoulder 321 of the first external thread pagoda head 32. The spring 6 is in a compressed state, pressing the sleeve 5 tightly against the mounting plate 2.
[0039] In this preferred embodiment, the shoulder 321 of the first external thread pagoda head 32 is the portion of the first external thread pagoda head 32 whose axial projection extends beyond the threaded end. The sleeve 5 is fixedly connected to the threaded end of the first external thread pagoda head 32 and is connected to the nozzle 3 as a whole. The sleeve 5, the mounting plate 2, and the spring 6 are sequentially sleeved on the first external thread pagoda head 32. The sleeves 5 at both ends and the shoulder 321 of the first external thread pagoda head 32 limit the mounting plate 2 and the spring 6, so that the spring 6 is always in a compressed state, pressing the sleeve 5 tightly onto the mounting plate 2, that is, pressing the nozzle 3 tightly onto the mounting plate 2. At this time, when the nozzle 3 slides along the slide groove 21, the contact position of the spring 6 on the mounting plate 2 changes, and sliding friction occurs between the two. When the nozzle 3 moves to any position and stops, the spring 6 can press the nozzle 3 tightly onto the mounting plate 2, so that the nozzle 3 and the mounting plate 2 maintain a stable connection in the direction perpendicular to the slide groove 21.
[0040] Specifically, the sleeve 5 is provided with an internal thread, which is threaded to the threaded end of the first external thread pagoda head 32.
[0041] Preferably, a first pad 8 and a second pad 9 are also fitted on the first external thread pagoda head 32. The first pad 8 is located between the spring 6 and the mounting plate 2, and the second pad 9 is located between the spring 6 and the shoulder 321 of the first external thread pagoda head 32.
[0042] In this embodiment, a first pad 8 is provided between one end of the spring 6 and the mounting plate 2, so that when the nozzle 3 slides in the groove 21, the first pad 8 and the mounting plate 2 will slide and rub against each other, thereby reducing the wear of the spring 6. A second pad 9 is provided between the spring 6 and the shoulder 321 of the first external thread pagoda head 32, increasing the contact area of the spring 6, so that the end face of the shoulder 321 of the first external thread pagoda head 32 is not insufficient to resist the spring 6, which would lead to the failure of the limiting function of the spring 6. The second pad 9 can also reduce the wear of the other end of the spring 6.
[0043] Preferably, the first pad 8 has a groove on the side facing the spring 6 to engage the spring 6, ensuring the stability of the contact between the first pad 8 and the spring 6; the second pad 9 also has a groove on the side facing the spring 6 to engage the spring 6, ensuring the stability of the contact between the second pad 9 and the spring 6. Further, the side of the second pad 9 away from the spring 6 preferably also has a groove to engage the shoulder 321 of the first external thread pagoda head 32, ensuring the stability of the contact between the second pad 9 and the shoulder 321 of the first external thread pagoda head 32.
[0044] More preferably, the mounting plate 2 has a plurality of positioning holes 22 on at least one side of the slide groove 21, and the positioning holes 22 are spaced apart along the length of the slide groove 21; the sleeve 5 is provided with a wing plate 51, and the wing plate 51 is provided with a buckle 52 that matches the shape and size of the positioning hole 22. When the sleeve 5 is pressed on the mounting plate 2, the buckle 52 can be engaged in the positioning hole 22.
[0045] In this preferred embodiment, when the buckle 52 on the wing plate 51 is aligned with the positioning hole 22 on the mounting plate 2, the spring 6 will press the buckle 52 into the positioning hole 22, thus locking the nozzle 3 onto the mounting plate 2. Figure 3 As shown in the left figure. When it is necessary to change the spraying point, the spring 6 allows the nozzle 3 to move a certain distance in a direction perpendicular to the slide 21, which can pull the nozzle 3 or the sleeve 5 away from the mounting plate 2, such as... Figure 3 As indicated by the middle arrow, the clip 52 is moved away from the mounting plate 2 and disengaged from the positioning hole 22. At this time, the nozzle 3 is released from the positioning hole 22. Figure 3 As shown in the right figure, the nozzle 3 can slide along the slide groove 21. After reaching the target position, the buckle 52 is released after being aligned with the target positioning hole 22 again. The spring 6 presses the buckle 52 in to complete the fixing of the nozzle 3.
[0046] Preferably, multiple positioning holes 22 are provided on both sides of the slide groove 21, and two buckles 52 are provided on the wing plate 51 of the sleeve 5, which correspond to the positioning holes 22 on both sides of the slide groove 21, so that the nozzle 3 is more stably positioned and connected to the mounting plate 2.
[0047] Preferably, the mounting plate 2 is provided with a first code corresponding to each positioning hole 22, which facilitates process recording and makes it convenient to record the location between different products.
[0048] In a specific preferred embodiment, such as Figure 4 As shown, the mounting plate 2 has densely packed positioning holes 22, which are coded and named using a coordinate system. The positioning holes 22 are arranged numerically along the direction of the slide groove 21 and alphabetically along the direction perpendicular to the slide groove 21. For example, in... Figure 4The first code for the top nozzle 3 is C23, the first code for the middle nozzle 3 is D17, and the first codes for the two bottom nozzles 3 are E12 and E18 respectively. Furthermore, nozzle 3 can also be represented by a combination of the first and second codes, for example... Figure 4 The topmost nozzle 3 is recorded as MB06-C23, where MB06 refers to the number of the outlet 11 of the spray box 1 to which this nozzle 3 is connected ( Figure 2 This facilitates recording the robot system's control of its opening degree, while C23 represents the coordinate position of the nozzle 3 on the mounting plate 2. In this preferred embodiment, the process inspection checklist allows the spraying device to quickly switch to dedicated spraying for the corresponding mold even when the mold is frequently changed.
[0049] The spraying device for die-casting molds of this utility model includes a spraying box 1, a mounting plate 2, and a nozzle 3. By setting the nozzle 3 on the mounting plate 2 outside the spraying box 1 and connecting the nozzle 3 to the discharge port 11 of the spraying box 1 through a connecting pipe 4, the nozzle 3 can slide along the slide groove 21 of the mounting plate 2 to any position and then lock on the mounting plate 2. This allows the nozzle 3 of this spraying device to quickly change position for the mold surface of different molds, so that this spraying device can be quickly transformed into a special spraying box for different product mold structures.
