[0041] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments.

[0042] Please refer to Figures 1 to 3 An automatic mold release agent spraying device includes a mold release agent spray gun 3, a robotic arm 1, and a control device 2;

[0043] The release agent spray gun 3 is mounted on the robotic arm 1. The robotic arm 1 is used to move the release agent spray gun 3 and adjust the nozzle orientation of the release agent spray gun 3. The control device 2 is used to control the movement of the robotic arm 1.

[0044] As can be seen from the above description, the beneficial effects of this utility model are as follows: the release agent spray gun 3 is set on the robotic arm 1 which is automatically controlled by the control device 2; when spraying the release agent, the release agent spray gun 3 is controlled to move toward the injection mold 5 and spray the release agent into the mold cavity, so as to replace the manual operation of the release agent spray gun 3. This can realize the automated spraying of the release agent. The robotic arm 1 can realize complex motion trajectories in three-dimensional space, so that the release agent spray gun 3 can flexibly reach different positions and postures, thereby improving the release agent spraying efficiency and product yield.

[0045] Furthermore, the control device 2 is also used to control the nozzle air pressure and nozzle opening of the release agent spray gun 3.

[0046] As can be seen from the above description, while the control device 2 controls the movement and nozzle angle of the release agent spray gun 3 through the robotic arm 1, it can also control the nozzle air pressure and nozzle opening of the release agent spray gun 3. This allows for precise control of the amount and range of release agent sprayed, avoiding waste of release agent, reducing production costs, and improving the uniformity and consistency of release agent spraying.

[0047] Furthermore, the robotic arm 1 includes an angle adjustment assembly and a displacement adjustment assembly;

[0048] The release agent spray gun 3 is connected to the movable end of the angle adjustment component, the angle adjustment component is connected to the movable end of the displacement adjustment component, and the control device 2 is electrically connected to the angle adjustment component and the displacement adjustment component respectively.

[0049] The angle adjustment component is used to control the nozzle orientation of the release agent spray gun 3, and the displacement adjustment component is used to move the angle adjustment component and the release agent spray gun 3.

[0050] As described above, the angle adjustment component allows for flexible adjustment of the nozzle orientation of the release agent spray gun 3. During the demolding process of complex molds, different parts of the mold may require release agent spraying from different angles. The angle adjustment component allows the spray gun to accurately align with the target position, achieving precise spraying and ensuring that all corners of the mold are evenly covered with release agent, thus effectively improving the demolding effect. The displacement adjustment component allows movement of both the angle adjustment component and the release agent spray gun 3, enabling the spray gun to move within a larger spatial range. For molds that are large or irregularly shaped, the spray gun can be moved to different positions for spraying operations via the displacement adjustment component.

[0051] Furthermore, the angle adjustment assembly includes a first rotary drive 11 and a second rotary drive 12;

[0052] The first rotary drive 11 is connected to the movable end of the displacement adjustment assembly, the second rotary drive 12 is connected to the rotary shaft of the first rotary drive 11, the release agent spray gun 3 is connected to the rotary shaft of the second rotary drive 12, and the axial direction of the rotary shaft of the first rotary drive 11 is different from the axial direction of the rotary shaft of the second rotary drive 12.

[0053] The control device 2 is electrically connected to the second rotary drive 12 and the first rotary drive 11, respectively.

[0054] As can be seen from the above description, the rotation axes of the first rotary drive 11 and the second rotary drive 12 are in different directions. This allows the release agent spray gun 3 to be angled in two different dimensions so that the spray gun can quickly reach the appropriate spraying angle, which greatly shortens the equipment adjustment time, improves production efficiency, and enhances the adaptability and flexibility of the equipment to different production tasks.

[0055] Furthermore, the angle adjustment assembly also includes an extended connector 13;

[0056] The two ends of the extended connector 13 are respectively connected to the rotation shaft of the first rotary drive 11 and the second rotary drive 12.

[0057] As described above, the extended connector 13 allows for greater flexibility in the spatial positioning of the second rotary drive 12 and the connected release agent spray gun 3. In complex mold release scenarios, the spray gun may need to operate at different heights, depths, and angles. The extended connector 13 provides additional freedom, enabling the spray gun to more easily avoid protrusions or other obstacles on the mold and find the optimal spraying position, greatly improving operational flexibility and convenience.

[0058] Furthermore, the length of the extended connector 13 is adjustable.

[0059] As described above, the adjustable length allows for changes in the spray gun's radius of motion and angular range. When precise spraying of a specific angle or area of ​​the mold is required, the length of the extended connector 13 can be adjusted to allow the spray gun to approach the mold at the optimal angle and distance.

[0060] Furthermore, the displacement adjustment assembly includes a base 14 and a connecting swing arm 15;

[0061] The two ends of the connecting arm 15 are respectively connected to the base 14 and the angle adjustment assembly;

[0062] The control device 2 is electrically connected to the connecting swing arm 15, and the control device 2 can control the rotation of the connecting swing arm 15 relative to the base 14.

[0063] As described above, the connecting arm 15, when used in conjunction with the angle adjustment component, enables the spray gun to move omnidirectionally in space. The connecting arm 15 is responsible for moving the spray gun, while the angle adjustment component is responsible for adjusting the spray gun's angle. Their coordinated operation allows the spray gun to apply release agent at different positions and angles, greatly improving the flexibility and precision of the spraying process.

[0064] Furthermore, the connecting arm 15 includes at least two sub-connecting arms 151;

[0065] The sub-connecting arms 151 are rotatably connected to each other, with one sub-connecting arm connected to the base 14 and the other sub-connecting arm 151 connected to the angle adjustment assembly.

[0066] As described above, the multiple sub-connecting arms 151 can rotate relative to each other, significantly increasing the movement flexibility of the connecting swing arm 15. This allows the release agent spray gun 3 to reach more complex and narrower spatial positions; the relative rotation of each sub-connecting arm 151 adds a degree of freedom to the overall movement of the connecting swing arm 15. When spraying release agent onto the mold, the rotation angle and direction of each sub-connecting arm 151 can be precisely controlled according to specific spraying requirements, thereby achieving precise adjustment of the spray gun's position and attitude.

[0067] Furthermore, a mounting plate 16 is provided on the movable end of the angle adjustment component;

[0068] The release agent spray gun 3 is detachably mounted on the mounting plate 16.

[0069] As can be seen from the above description, when the release agent spray gun 3 malfunctions or needs maintenance, since it is detachably mounted on the mounting plate 16, the operator can quickly and easily remove the spray gun from the mounting plate 16 for inspection, repair or replacement of parts.

[0070] Please refer to Figure 1 An injection molding fixture, comprising a fixture table 4, an injection mold 5, and an automatic mold release agent spraying device as described above;

[0071] The injection mold 5, the robotic arm 1, and the control device 2 are distributed on the tooling table 4;

[0072] The robotic arm 1 is used to control the release agent spray gun 3 to move toward or away from the mold cavity of the injection mold 5 and to adjust the nozzle orientation of the release agent spray gun 3.

[0073] The beneficial effects of this utility model are as follows: the release agent spray gun 3 is set on the robotic arm 1 which is automatically controlled by the control device 2; when spraying the release agent, the release agent spray gun 3 is controlled to move toward the injection mold 5 and spray the release agent into the mold cavity, which replaces the manual operation of the release agent spray gun 3. This can realize the automated spraying of the release agent. The robotic arm 1 can realize complex motion trajectories in three-dimensional space, so that the release agent spray gun 3 can flexibly reach different positions and postures, thereby improving the release agent spraying efficiency and product yield.

[0074] Furthermore, the tooling table 4 is equipped with a mounting bracket 6;

[0075] The control device 2 is located on the mounting bracket 6.

[0076] As can be seen from the above description, mounting the control device 2 on the mounting bracket 6 can make the equipment layout on the tooling table 4 more reasonable; the mounting bracket 6 can provide a certain physical protection for the control device 2, reducing the risk of the control device 2 being accidentally damaged.

[0077] Please refer to Figures 1 to 3 Embodiment 1 of this utility model is as follows:

[0078] An automatic mold release agent spraying device includes a mold release agent spray gun 3, a robotic arm 1, and a control device 2. The mold release agent spray gun 3 is mounted on the robotic arm 1, which is used to move the mold release agent spray gun 3 and adjust the nozzle orientation of the spray gun 3. The control device 2 is used to control the movement of the robotic arm 1. The control device 2 is also used to control the nozzle air pressure and nozzle opening of the mold release agent spray gun 3.

[0079] It is understood that the robotic arm 1 of this application is not limited to the Cartesian robotic arm 1 with separate angle adjustment and displacement adjustment as described above, and may also employ cylindrical robotic arms, spherical robotic arms, parallel robotic arms, etc. The control device may therefore employ common control structures such as electrical boxes and PCs. These control structures and corresponding control methods and algorithms are widely used in the field and are well known to those skilled in the art. Those skilled in the art can flexibly select and adjust them as needed, and will not be described in detail here.

[0080] like Figure 1 As shown, the operation process of an automatic mold release agent spraying device includes:

[0081] When spraying release agent onto the mold cavity, control device 2 sends control commands to robotic arm 1, which then moves the release agent spray gun 3 to the designated position and adjusts the nozzle orientation. The control device connects to a solenoid valve via an air pipe and release agent pipeline to transmit signals and actions. Furthermore, the release agent spray gun 3 is equipped with a nozzle air pressure regulator and a nozzle opening regulator. Control device 2 is connected to both the nozzle air pressure regulator and the nozzle opening regulator to control the nozzle air pressure and nozzle opening of the release agent spray gun 3, accurately controlling the spraying speed and release agent content for each application, thus assisting in achieving uniform spraying.

[0082] In this embodiment, the robotic arm 1 includes an angle adjustment component and a displacement adjustment component; the release agent spray gun 3 is connected to the movable end of the angle adjustment component, and the angle adjustment component is connected to the movable end of the displacement adjustment component; the control device 2 is electrically connected to both the angle adjustment component and the displacement adjustment component; the angle adjustment component controls the nozzle orientation of the release agent spray gun 3, and the displacement adjustment component moves the angle adjustment component and the release agent spray gun 3. During tooling operation, the displacement adjustment component moves the release agent spray gun 3 to a position near the mold cavity where spraying is required, and then the angle adjustment component adjusts the nozzle orientation of the release agent spray gun 3.

[0083] In this embodiment, the movable end of the angle adjustment component is provided with a mounting plate 16; the release agent spray gun 3 is detachably mounted on the mounting plate 16.

[0084] Please refer to Figure 2 and Figure 3 Embodiment two of this utility model is as follows:

[0086] In this embodiment, the rotation control of the first rotary drive 11 and the second rotary drive 12 works together to allow for more variations in the direction in which the nozzle of the release agent spray gun 3 faces. For example, if the axial direction of the rotation axis of the first rotary drive 11 is set to be perpendicular to the axial direction of the rotation axis of the second rotary drive 12, the release agent spray gun can be rotated 360 degrees, allowing the release agent spray gun 3 to flexibly change the spraying direction and shorten the travel distance of the release agent spray gun 3.

[0087] The angle adjustment assembly also includes an extension connector 13. Both ends of the extension connector 13 are connected to the rotation shaft of the first rotary drive 11 and the second rotary drive 12, respectively. The length of the extension connector 13 is adjustable. As shown in the figure, the extension connector 13 can be composed of a sleeve 132 and a mounting base 131. Multiple mounting holes are provided on the mounting base 131, and the sleeve 132 is fixed to the mounting base 131 through these mounting holes. By adjusting the connection of the sleeve 132 to different mounting holes, the overall length of the extension connector 13 can be changed. The extension connector 13 and the first rotary drive 11 can be connected using a mounting flange 7, which provides good stability and facilitates disassembly.

[0088] In this embodiment, after the addition of the extended connector 13, the release agent spray gun 3 can extend the distance into the mold with the help of the extended connector 13, thereby meeting the spraying requirements of some mold cavities and inserts such as the ultra-large canopy edging assembly mold.

[0089] Please refer to Figure 2 Embodiment three of this utility model is as follows:

[0090] An automatic mold release agent spraying device, based on the above-described embodiment one or two, includes a displacement adjustment assembly comprising a base 14 and a connecting swing arm 15; both ends of the connecting swing arm 15 are connected to the base 14 and the angle adjustment assembly, respectively; a control device 2 is electrically connected to the connecting swing arm 15, and the control device 2 is capable of controlling the rotation of the connecting swing arm 15 relative to the base 14.

[0094] like Figure 1 As shown, two automatic release agent spraying devices can be distributed on the worktable near the injection mold 5. When the mold cavity of the injection mold 5 needs to be sprayed with release agent, the robotic arm 1 moves to control the release agent spray gun 3 to approach the mold cavity of the injection mold 5 and then perform the spraying action.

[0095] In summary, this utility model provides an automatic mold release agent spraying device and injection molding fixture, which mounts the mold release agent spray gun on a robotic arm automatically controlled by a control device. During mold release agent spraying, the device controls the mold release agent spray gun to move towards the injection mold and spray the mold release agent into the mold cavity, replacing the manual operation of the mold release agent spray gun. This achieves automated mold release agent spraying, improving spraying efficiency and product yield. The robotic arm mainly consists of an angle adjustment component and a displacement adjustment component, with rotating drive components of different rotational axis orientations working together to control the mold release agent spray gun, allowing the nozzle orientation to be flexibly changed at multiple angles. By utilizing the combination and variation of multiple connecting sub-arms, the moving direction and distance of the mold release agent spray gun can be flexibly changed to adapt to different on-site operating environments.
