Description

Technical Field

[0001] This utility model relates to the field of metal die casting machine technology, and in particular to a spraying device for a metal die casting machine. Background Technology

[0002] Whether it is molten metal or die-cast metal powder, a release agent needs to be sprayed onto the surface of the die-casting mold. The water in the water-based release agent evaporates instantly when it comes into contact with the high-temperature mold, which can carry away a large amount of heat (using the latent heat of vaporization of water), thereby quickly and effectively reducing the mold temperature and facilitating subsequent demolding.

[0003] Spraying equipment, in conjunction with a robotic arm, can perform multi-angle spray adjustment. For example, Chinese Patent Publication No. CN206912212U discloses a three-axis die-casting spraying industrial robot. The robot's base includes a base body and a first sealed box. A first drive device is housed within the first sealed box, and its output shaft is axially connected to the lower end of the spray arm. A second sealed box is laterally located at the upper end of the spray arm, housing a second drive device, whose output shaft is also axially connected to the second sealed box. The spray arm has a through-cavity at its center, with a third drive device housed within the cavity, partially extending out of the lower end of the cavity. A spraying integrated block is axially connected to the output shaft of the third drive device. Its advantages include good sealing and waterproofing due to the first drive device being located within the first sealed box, the second drive device within the second sealed box, and the third drive device within the cavity. It also boasts advantages such as long service life, low maintenance costs, small overall size, and simple structure.

[0004] In actual operation, multiple nozzles are connected to the mounting plate. Considering the dusty working environment of the die-casting equipment, the nozzles are prone to damage or blockage after long-term use. The lack of a sealing structure between the nozzle and the pipe means that after disassembling a single nozzle, the remaining nozzles cannot be used normally. In addition, the nozzles do not have an anti-blocking structure, making it difficult to clear blockages quickly. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of the existing technology, such as the lack of a sealing structure between the nozzle and the pipe fitting, and the difficulty in quickly clearing the nozzle, and to propose a spraying device for a metal die-casting machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a spraying device for a metal die-casting machine, including a mounting frame connected to the drive end of a robotic arm, and several spraying mechanisms mounted on the side of the mounting frame, each spraying mechanism consisting of a spraying component and an anti-clogging component;

[0008] The spray assembly includes a connecting seat and an air pipe connector. The opposite ends of the connecting seat and the air pipe connector are detachably connected by a connecting structure, and the opposite ends are respectively sealed to the liquid supply device and the nozzle. The connecting structure is used to disassemble the air pipe connector and seal the connecting seat.

[0009] The anti-clogging component is used to prevent the nozzle from becoming clogged.

[0010] Furthermore, the connecting seat is fixedly connected to the side of the mounting bracket, and a sealing element is slidably connected inside the connecting seat via a compression spring. The sealing element is used to block the outlet of the connecting seat.

[0011] Furthermore, the tracheal connector is internally fixedly connected with a first support member and a second support member. When the tracheal connector is movably inserted into the connecting seat, the first support member presses against and drives the sealing member to retract inward.

[0012] Furthermore, the first support member has a cavity, and both the first support member and the second support member have a water channel that communicates with the internal cavity of the air pipe connector.

[0013] Furthermore, the connection structure includes a sleeve portion, the outer periphery of the connecting seat is slidably connected to the sleeve portion via a first spring, and a plurality of balls are movably connected to the outer wall of the end of the connecting seat. The air pipe connector is provided with an annular groove at the end, and the sleeve portion presses against the balls so that the balls are stopped in the annular groove.

[0014] Furthermore, the anti-clogging component includes a cleaning needle, which is slidably connected to the first support member and the second support member. A second spring is sleeved around one end of the cleaning needle via a baffle, and the other end of the second spring abuts against the inner wall of the first support member.

[0015] Furthermore, the cleaning needle is concentrically arranged with the nozzle orifice of the spray head, and the free end of the cleaning needle has a needle tip, which passes through the nozzle orifice of the spray head.

[0016] The present invention provides a spraying device for a metal die-casting machine, which has the following advantages: In this invention, the air pipe connector and the connecting seat are sealed and detachably connected through a connecting structure. When a single nozzle needs to be disassembled and replaced, the air pipe connector can be disassembled directly, and then the outlet of the connecting seat can be blocked by a sealing component, so as not to affect the normal use of the remaining nozzles.

[0017] After disassembling the air tube connector, the cleaning needle can be moved by pushing. The cleaning needle clears the nozzle hole through the needle tip, preventing unnecessary waste caused by nozzle blockage and replacement. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-4 A spraying device for a metal die-casting machine includes a mounting frame 1, which is connected to the drive end of a robotic arm. Several spraying mechanisms are installed on the side of the mounting frame 1, and each spraying mechanism consists of a spraying component 2 and an anti-clogging component 3.

[0025] The spray assembly 2 includes a connecting seat 21 and an air pipe connector 22. The opposite ends of the connecting seat 21 and the air pipe connector 22 are detachably connected by a connecting structure 4, and the opposite ends are respectively sealed to the liquid supply device and the nozzle 23. The connecting structure 4 is used to disassemble the air pipe connector 22 and seal the connecting seat 21.

[0026] The anti-clogging component 3 is used to prevent the nozzle 23 from becoming clogged.

[0027] In some embodiments, the mounting frame 1 is moved between the die-casting molds by a robotic arm, and a water-based release agent is sprayed on the surface of the mold in conjunction with a spraying mechanism. The robotic arm can also be used to adjust the spraying angle of the spraying mechanism. The robotic arm is existing technology, and its specific principle and connection method will not be described in detail here.

[0028] Furthermore, multiple spray mechanisms are connected to the liquid supply device, and liquid delivery fittings can be individually connected between the spray mechanism and the liquid supply device.

[0029] It should be added that the air tube connector 22 is existing technology. Its specific structure is as follows: the connector body contains one or more claws (or "claws") with sharp cutting edges, and an O-ring or rubber ring for sealing. When attempting to pull the nozzle 23 outwards, the beveled design of the claws tightens the grip, causing the cutting edges to embed deeper into the air tube, forming a strong mechanical lock. Pressing the release sleeve (or top ring) on ​​the outside of the connector pushes the claws inwards, disengaging their cutting edges from the outer wall of the nozzle 23 connecting tube, at which point the nozzle 23 can be easily pulled out.

[0030] Specifically, the nozzle 23 includes a nozzle and a connecting pipe, with the connecting pipe fixed inside the air pipe connector 22.

[0031] Furthermore, the connecting seat 21 is fixedly connected to the side of the mounting bracket 1, and a sealing member 25 is slidably connected inside the connecting seat 21 through a compression spring 24. The sealing member 25 is used to block the outlet of the connecting seat 21.

[0032] Furthermore, the tracheal connector 22 is internally fixedly connected with a first support member 26 and a second support member 27. When the tracheal connector 22 is movably inserted into the connecting seat 21, the first support member 26 presses against and drives the sealing member 25 to retract inward.

[0033] More specifically, the first support member 26 has a cavity, and both the first support member 26 and the second support member 27 have a water channel 28 that connects to the cavity inside the air pipe connector 22.

[0034] In this embodiment, after the connecting seat 21 and the tracheal connector 22 are movably inserted, the first support member 26 presses against and drives the sealing member 25 to retract inward, thereby connecting the internal cavity between the connecting seat 21 and the tracheal connector 22.

[0035] After the connecting seat 21 is separated from the air pipe connector 22, the sealing element 25, under the action of the compression spring 24, seals the outlet of the connecting seat 21, thereby achieving a sealing effect.

[0036] In general, the connecting structure 4 includes a sleeve part 41, the outer periphery of the connecting seat 21 is slidably connected to the sleeve part 41 by a first spring 42, and a plurality of balls 43 are movably connected to the outer wall of the end of the connecting seat 21. The air pipe connector 22 is provided with an annular groove 44 at its end, and the sleeve part 41 presses against the balls 43 so that the balls 43 are stopped in the annular groove 44.

[0037] In some embodiments, the connection structure 4 is specifically a quick-connect coupling as used in the prior art, such as... Figure 3As shown, the two ends of the first spring 42 abut against the protruding part of the outer wall of the connecting seat 21 and the inner protruding part of the sleeve part 41 respectively. The sleeve part 41 presses against the ball 43, thereby driving the ball 43 to engage in the annular groove 44, so as to achieve the fixed freedom between the connecting seat 21 and the air pipe connector 22.

[0038] It is worth mentioning that the connector 21 has a stepped section inside, and a sealing ring is provided on the stepped section. The sealing ring is used to further improve the sealing between the connector 21 and the air pipe connector 22.

[0039] Of course, sealing rings also need to be installed on the sealing surface of the sealing component 25, as well as between the nozzle 23 and the air pipe connector 22.

[0040] Furthermore, the anti-clogging component 3 includes a cleaning needle 31, which is slidably connected to the first support member 26 and the second support member 27. A second spring 32 is sleeved around one end of the cleaning needle 31 through a baffle, and the other end of the second spring 32 abuts against the inner wall of the first support member 26.

[0041] Finally, the cleaning needle 31 is concentrically arranged with the nozzle of the nozzle 23, and the free end of the cleaning needle 31 has a needle tip 33, which passes through the nozzle of the nozzle 23.

[0042] In some embodiments, the first support member 26 and the second support member 27 are used to support and guide the cleaning needle 31, specifically, as shown in the example. Figure 3 , 4 As shown, under the support of the second spring 32, the cleaning needle 31 avoids the spray hole of the nozzle 23, thus not affecting the normal use of the nozzle 23;

[0043] After pressing the cleaning needle 31 to move it, the needle tip 33 passes through the spray hole of the nozzle 23, and cleaning can be performed;

[0044] More specifically, such as Figure 2 As shown, the end of the cleaning needle 31 away from the needle tip 33 extends to the periphery of the first support member 26. Pressing this end of the cleaning needle 31 can drive it to move. The end of the sealing member 25 is provided with a relief groove, which is used to avoid the cleaning needle 31 and prevent the cleaning needle 31 from blocking the nozzle 23 after docking.

[0045] Working method: Several sets of spraying mechanisms are installed on the mounting frame 1. The mounting frame 1 is moved by the mechanical arm. The mounting frame 1 cooperates with the spraying mechanism to spray water-based release agent on the surface of the die-casting mold.

[0046] When it is necessary to disassemble the clogged or damaged nozzle 23, the sliding sleeve 41 unlocks the ball 43, and the air pipe connector 22 can be pulled out directly. After the first support 26 separates from the sealing member 25, the sealing member 25 seals the outlet of the connecting seat 21 under the action of the compression spring 24.

[0047] Then, press the cleaning needle 31 to clean the nozzle 23 through the needle tip 33.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
