[0002] The release agent spraying device is an important auxiliary device for various casting equipment. Its main purpose is to efficiently and evenly apply the release agent to the mold surface. The release agent is a surfactant that can effectively reduce the adhesion between the mold and the molding material, so that the product can be easily and non-destructively separated from the mold after the processing is completed. This feature plays a vital role in improving production efficiency, ensuring product quality, reducing mold wear and extending the service life of the mold.

[0003] However, due to design problems, the traditional die-casting machine release agent spraying device often causes uneven release agent spraying, resulting in poor demolding effect in some areas of the mold, reducing the molding quality and life of the die-casting. In addition, the traditional spraying device requires manual operation or manual adjustment, which greatly reduces the spraying efficiency, and because the design of the spraying device is very complicated, it increases the difficulty of equipment maintenance. Therefore, it is urgently needed to design a die-casting machine release agent spraying device with a simple structure, high spraying efficiency and nozzles that are not easy to clog. Utility Model Content

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0019] like Figure 1-3 As shown, a high-efficiency spraying device for a die-casting machine release agent specifically comprises: an air-controlled valve 1, a nozzle mounting frame 2, an adjusting rod 3, an adjusting seat 4, a spray gun head 5, an air-controlled valve control air pipeline 6, a release agent inlet pipeline 7, a compressed air inlet pipeline 8 and a release agent storage box 13;

[0020] A support plate 18 is installed above the release agent storage box 13, a support column 17 is welded on the support plate 18, a flange 12 is connected above the support column 17, and the flange 12 is connected to the manipulator 14;

[0021] The release agent storage box 13 is connected with a release agent inlet pipe 7 above;

[0022] The side of the release agent storage box 13 is connected to a plurality of air-controlled valves 1;

[0023] The upper part of the air control valve 1 is connected to an air control valve control air pipeline 6;

[0024] The lower part of the air control valve 1 is connected to a release agent delivery pipe 16;

[0025] In this embodiment, preferably, there are four air-controlled valves 1, which are symmetrically distributed on both sides of the release agent storage box 13 in a rectangular shape;

[0026] The release agent delivery pipe 16 is provided with a one-way valve to control the one-way transportation of the release agent in the release agent delivery pipe 16;

[0027] The release agent delivery pipe 16 first merges with the compressed air inlet pipe 8, and the merged air path is then connected to the spray gun head 5; the release agent in the release agent delivery pipe 16 is accelerated by the high-speed compressed air in the compressed air inlet pipe 8, and finally sprayed out from the spray gun head 5.

[0028] The spray gun head 5 is mounted on the spray head mounting frame 2, and a waist-shaped hole 15 is opened on the upper top surface of the spray head mounting frame 2; an adjustment seat 4 is mounted on the spray head mounting frame 2, and the adjustment seat 4 has a through-hole feature; one end of the adjustment rod 3 passes through the through-hole of the adjustment seat 4, and the other end is fixedly connected to the release agent storage box 13;

[0029] The adjustment seat 4 is equipped with a No. 1 nozzle knob 9, a No. 2 nozzle knob 10 and a No. 3 nozzle knob 11, wherein the No. 2 nozzle knob 10 is used to flexibly connect the nozzle mounting frame 2 and the adjustment seat 4, and the No. 3 nozzle knob 11 is connected to the adjustment seat 4 through a waist-shaped hole 15 opened above the mounting frame 2, and is used to adjust the angle between the nozzle mounting frame 2 and the adjustment seat 4; since the spray gun head 5 is mounted on the nozzle mounting frame 2, the No. 3 nozzle knob 11 plays a role in adjusting the deflection angle of the spray gun head 5 in the horizontal plane. The No. 1 nozzle knob 9 passes through the adjustment seat 4, and plays a role in locking the relative position of the adjustment rod 3 and the adjustment seat 4. The No. 1 nozzle knob 9 is used to adjust the deflection angle of the spray gun head 5 in the vertical plane. In summary, by adjusting the three nozzle knobs, the spatial posture of the spray gun head 5 can be controlled, thereby achieving precise spraying.

[0030] In order to reduce the overall weight of the device, the air control valve control air pipeline 6, the release agent inlet pipeline 7 and the compressed air inlet pipeline 8 are all made of polymer materials.

[0031] The number of the spray gun heads 5 is the same as that of the air control valves 1, namely four in total, which are symmetrically distributed in a rectangular shape on both sides of the release agent storage box 13. The outlet directions of the two spray gun heads on the same side are consistent, and the four spray gun heads spray simultaneously to obtain higher spraying efficiency.

[0032] The outlet of the spray gun head 5 is provided with a groove shrinkage, the function of which is to form a more concentrated and delicate spray at the outlet, so that the release agent can be evenly sprayed on the mold surface, which is beneficial to improve the surface quality of the die-casting and reduce defects or defective products caused by uneven spraying. The design of the compact spray gun head is relatively simple and easy to clean and maintain.

[0033] The working principle of the utility model is as follows:

[0034] During the spraying process, the air-controlled valve control gas enters the air-controlled valve through the air-controlled valve control gas pipeline 6, driving the valve core inside the air-controlled valve 1 to open; the interior of the release agent storage box 13 is connected to the release agent delivery pipeline 16, and the release agent is delivered to the interior of the release agent delivery pipeline 16;

[0035] At the same time, compressed air enters the release agent delivery pipe 16 through the compressed air inlet pipe 8, mixes with the release agent therein, and finally sprays out from the spray gun head 5. During the spraying process, the supply amount of the release agent is adjusted by the air control valve 1 to meet different spraying requirements.

[0036] When spraying is completed, the air control valve controls the air pipeline 6, and the release agent storage box 13 is disconnected from the spray gun head 5 through the release agent delivery pipeline 16; the spraying operation stops; however, the spray gun head 5 can still spray compressed air to accelerate the film formation of the release agent.

[0037] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values ​​of the parts and steps described in these embodiments do not limit the scope of the utility model. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0038] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0039] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0040] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
