Description

Technical Field

[0001] This invention relates to the field of mold lubricant spraying technology, and in particular to a mold spraying device. Background Technology

[0002] In the hot forging process of various profiles and parts, the working environment of the dies is extremely harsh, requiring them to withstand significant loads and contact stress between the billet and the die wall. Therefore, die lubrication needs to be considered during production. Currently, in hot forging production, die lubrication is usually achieved by manually applying lubricant, such as graphite, to the die using a handheld spray gun to improve die life and product quality. However, this manual spraying method is inconvenient, with significant interference during each removal and placement of the spray gun, resulting in low efficiency. Furthermore, manual spraying easily leads to uneven spraying or dead zones, with graphite accumulating and wasting material, making it unsuitable for precision forging and mass production. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a mold spraying device that provides uniform spraying, reduces lubricant waste, and improves spraying efficiency.

[0004] To solve the above-mentioned technical problems, one technical solution adopted by the present invention is: to provide a mold spraying device for spraying lubricant onto a mold along a predetermined trajectory, including a spray gun and a moving mechanism for controlling the spray gun to enter between the upper mold and the lower mold and move along the predetermined trajectory; the spray gun includes a nozzle, a pipeline communicating with the nozzle to deliver the lubricant to the nozzle, a flow control valve placed on the pipeline, and a valve control mechanism for controlling the flow control valve.

[0005] Furthermore, the pipeline includes a lubricant pipeline and an air blowing pipeline, the output ends of which are connected to the nozzle; the flow control valve includes a lubricant flow control valve located at the lubricant pipeline and an air flow control valve located at the air blowing pipeline, and the valve control mechanism is used to sequentially control the opening of the air flow control valve and the lubricant flow control valve, so that the nozzle sequentially blows air onto the upper mold and / or the lower mold and sprays lubricant onto the upper mold and / or the lower mold.

[0006] Furthermore, the lubricant pipeline and the air blowing pipeline are arranged side by side, and the air flow control valve and the lubricant flow control valve are arranged side by side on the lubricant pipeline and the air blowing pipeline. The height of the air flow control valve is higher than that of the lubricant flow control valve. The valve control mechanism includes a pressing handle and a pressing unit located above the air flow control valve and the lubricant flow control valve. The pressing unit includes a primary pressing unit for driving the pressing handle to press down to open the air flow control valve and a secondary pressing unit for driving the pressing handle to continue pressing down to open the lubricant flow control valve.

[0007] Furthermore, the valve control mechanism also includes a pivot seat, one end of the pressing handle is pivotally connected to the pivot seat so as to be able to rotate vertically around the pivot axis, and the other end of the pressing handle extends upward toward the pressing unit; the valve control mechanism also includes a pressing part disposed above the other end of the pressing handle, the primary pressing unit includes a first vertical lifting part and a fixed part connected to the first vertical lifting part, and the secondary pressing unit is a second vertical lifting part disposed on the fixed part and the output shaft is connected to the pressing part.

[0008] Furthermore, the pressing handle includes a pressure seat and an inclined handle. One end of the pressure seat is pivotally connected to the pivot seat, and the other end is located above the air flow control valve and the lubricant flow control valve.

One end of the inclined handle is connected to the end of the pressure seat away from the pivot seat, and the other end is upward and gradually inclined towards the downward pressing part and located below the downward pressing part.

[0009] Furthermore, it also includes a material-grabbing mechanism connected to the moving mechanism. The material-grabbing mechanism includes a material-grabbing arm arranged parallel to the pipeline, a material-grabbing claw disposed at the material-grabbing end of the material-grabbing arm, and a drive unit for driving the material-grabbing claw to clamp or release. The material-grabbing claw is located between the nozzle and the moving mechanism, and the horizontal distance between the material-grabbing claw and the nozzle must satisfy the condition that when the nozzle is operating, the material-grabbing claw is located outside the side of the upper and lower molds facing the material-grabbing claw.

[0010] Furthermore, the material handling mechanism also includes a mounting base connected to the material handling end of the material handling arm. The mounting base has a mounting groove formed at one end near the material handling claw for the material handling claw to be installed therein. The mounting base also has a through hole with one end communicating with the mounting groove and the other end penetrating the mounting base towards the drive unit. The output shaft of the drive unit passes through the through hole and is connected to the material handling claw.

[0011] The material-grabbing claw includes a first gripper and a second gripper. One end of the first gripper and the second gripper is rotatably disposed in the mounting groove as a pivot end, and the other end of the first gripper and the second gripper is exposed in the mounting groove as a clamping end. The pivot ends of the first gripper and the second gripper each have a first elongated pivot hole near the drive unit and a first pivot hole near the clamping end. The first elongated pivot holes of the first gripper and the second gripper are both pivotally connected to a first pivot shaft. The first pivot holes are rotatably connected to the mounting groove through a second pivot shaft. The drive unit is a linear drive unit. The output shaft of the linear drive unit is connected to the first pivot shaft to drive the first pivot shaft to move in the direction of the clamping end and in the direction away from the clamping end, thereby causing the first gripper and the second gripper to open and close.

[0012] Furthermore, the first gripper includes a first gripping finger and a first gripping seat disposed on the first gripping finger near the mounting base. The first gripping seat includes a first upper gripping plate near the upper end of the first gripping finger and a first lower gripping plate near the lower end of the first gripping finger. The first upper gripping plate includes a first upper gripping segment extending from the first gripping finger towards the mounting base and a second upper gripping segment extending from the first upper gripping segment towards the second gripper. The first lower gripping plate is parallel and located below the first upper gripping segment. The second gripper includes a second gripping finger and a second gripping seat disposed on the second gripping finger near the mounting base. The clamping seat includes a second lower clamping plate near the lower end of the second clamping finger and a second upper clamping plate near the upper end of the second clamping finger.

The first lower clamping plate is located between the first clamping finger and the second lower clamping segment.

[0013] The first upper clamping plate and the second upper clamping plate form a detachable top plate, and the first lower clamping plate and the second lower clamping plate form a detachable bottom plate. A pivot space is formed between the top plate and the bottom plate. The first gripper also includes a bent first pivot connecting rod disposed in the pivot space as its pivot end, and the second gripper also includes a bent second pivot connecting rod disposed in the pivot space as its pivot end. The first pivot connecting rod and the second pivot connecting rod each include a bent portion that is far apart from each other and on the same straight line, a first inclined rod that extends from the bent portion toward the drive unit and in an inclined direction toward the opposite direction, and a second inclined rod that extends from the bent portion toward the two gripping fingers and in an inclined direction toward the opposite direction. The first elongated pivot hole is formed at the end of the first inclined rod and the second inclined rod near the drive unit. The first pivot hole is formed at the bent portion, and the second elongated pivot hole is formed at the end of the second inclined rod away from the first inclined rod.

[0014] The first upper clamping section and the first lower clamping plate, as well as the first lower clamping section and the second upper clamping plate, are each provided with a second pivot hole corresponding to the second elongated pivot hole. The second pivot hole and the second elongated pivot hole are pivotally connected together by a third pivot shaft.

[0015] Both the second upper clamping section and the second lower clamping section have a third elongated pivot hole corresponding to the first pivot hole; the second pivot shaft passes through the first pivot hole, the third elongated pivot hole on the second upper clamping section and the second lower clamping section, and both the upper and lower ends of the second pivot shaft are pivotally connected to the upper and lower side walls of the mounting groove.

[0016] Furthermore, the material handling mechanism also includes a conveying unit disposed below the material handling arm, the conveying unit being used to convey the product taken out by the material handling mechanism to the next destination location.

[0017] Furthermore, the moving mechanism is a three-axis moving mechanism capable of driving the spray gun to move along the X-axis, Y-axis and Z-axis directions.

[0018] The mold spraying device of the present invention has the following effects: both the air blowing pipeline and the lubricant pipeline are connected to the nozzle, and by controlling the opening of the air flow control valve, air is first blown to remove debris from the upper mold and / or lower mold. Then, the air flow control valve and the lubricant flow control valve are simultaneously controlled to mix the lubricant and air at the nozzle to form an atomized lubricant. This not only cleans the upper mold and / or lower mold before lubrication, allowing for more comprehensive spraying and lubrication, but also enables the mixing of air and lubricant to achieve an atomization effect, resulting in a larger volume of atomized lubricant and greater lubricant conservation. Furthermore, the material handling mechanism is integrated with the spray gun. The moving mechanism enables material handling, air blowing, and lubrication operations to be performed sequentially through a single control module and a single moving mechanism, saving manufacturing costs and reducing equipment size. The valve control mechanism precisely controls the opening of the air flow control valve and the lubricant flow control valve, ensuring thorough mixing of the lubricant and air and improving the quality of the atomized lubricant. The designed upper and lower mold nozzles, controlled by the moving mechanism, move along a predetermined trajectory for spraying, resulting in a more comprehensive and uniform spraying area, solving problems such as lubricant accumulation and waste, and spraying dead zones caused by uneven spraying in traditional technologies.

[0040] Please see Figure 1 and Figure 2The mold spraying device of this invention is used to spray lubricant onto a mold along a predetermined trajectory, specifically for spraying lubricant onto the mold's parting surface, cavity, and other parts along a predetermined trajectory after hot forging product A1. The mold spraying device includes a moving mechanism 100 capable of moving along the predetermined trajectory, a spray gun 200 mounted on the moving mechanism 100, and a material handling mechanism 300 mounted on the moving mechanism 100. In the illustrated embodiment, the moving mechanism 100 is a three-axis moving mechanism capable of driving the spray gun 200 to move along three axes: a first horizontal direction (hereinafter referred to as the X-axis direction), a second horizontal direction (hereinafter referred to as the Y-axis direction), and a vertical direction (hereinafter referred to as the Z-axis direction). It should be understood that the moving mechanism 100 is not limited to a three-axis moving mechanism; for example, the moving mechanism 100 can also be replaced by a robotic arm, as long as the moving mechanism 100 can drive the spray gun 200 to operate along the predetermined trajectory.

[0041] The three-axis moving mechanism is controlled by a control module (not shown in the figure). The control module pre-stores a predetermined movement trajectory for path planning of the three-axis moving mechanism, and controls the movement of the three-axis moving mechanism through the predetermined movement trajectory. The control module is disposed in a control box 410, which can be defined as being located outside one side of the mold along the X-axis direction. The top surface of the control box 410 can serve as the worktable 411 of the moving mechanism 100. As an example, the moving mechanism 100 is mounted on the worktable 411 and includes a vertical lifting module (hereinafter referred to as Z-axis moving module 110) capable of lifting and lowering along the Z-axis direction, a first moving module (hereinafter referred to as X-axis moving module 120) moving along the X-axis direction, and a second moving module (hereinafter referred to as Y-axis moving module 130) moving along the Y-axis direction.

[0042] The top surface of the control housing 410 has a first through hole (not shown) through which the Z-axis movement module 110 passes. The lower end of the Z-axis movement module 110 is disposed in the control housing 410, and the upper end passes through the first through hole and is exposed on the top surface of the control housing 410. The Z-axis movement module 110 is a vertically arranged first linear module, and the output shaft of the first linear module is vertically upward and connected to the lower end of the X-axis movement module 120.

[0043] The Y-axis movement module 130 is mounted on the top surface of the control housing 410 via a mounting platform and is located vertically between the Z-axis movement module 110 and the X-axis movement module 120. The Y-axis movement module 130 is also connected to the X-axis movement module 120 via a guide module 140. The mounting platform has a mounting surface 150 located above the control housing 410, and a second through hole 151 is provided on the mounting surface 150 at a position corresponding to the first through hole. The Y-axis moving module 130 includes a slide rail 131 and a second linear module 132 arranged along the X-axis direction on both sides of the second through hole 151. The slide rail 131 and the second linear module 132 are both distributed along the Y-axis direction. A slide plate 133 is slidably connected to the slide rail 131 and the second linear module 132. The slide plate 133 is located parallel above the mounting platform 150, and a third through hole 134 is provided at the position of the slide plate 133 corresponding to the second through hole 151. The cross-sectional area of ​​the third through hole 134 is smaller than the cross-sectional area of ​​the second through hole 151. On the horizontal projection plane, the second through hole 151 has a portion that overlaps with the third through hole 134 and a non-overlapping portion located around the overlapping portion. The guide module 140 includes guide holes (not shown) formed on the slide plate 133 at the corresponding side of the third through hole 134, guide sleeves 141 correspondingly disposed in each guide hole, guide rods 142 passing through each guide sleeve 141, and connectors 143 connected to the lower ends of the guide rods 142. On a horizontal projection plane, the guide holes, guide sleeves 141, and guide rods 142 are located at the non-overlapping portion of the third through hole 134. The connector 143 is a connecting frame disposed around the outer periphery of the first linear module. The lower end of the guide rod 142 is connected to the connecting frame, and the upper end is connected to the lower end of the X-axis moving module 120. The X-axis moving module 120 includes an X-axis frame 121 with one end connected to the output shaft of the Z-axis moving module 110 and the other end extending along the X-axis direction toward the mold, and a third linear module 122 fixed along the X-axis direction on the X-axis frame 121.

[0044] Please see Figure 3 , Figure 4 , Figure 5 and Figure 6The spray gun 200 is connected to the output shaft of the X-axis moving module 120 via a mounting bracket 210 to enable movement along the X-axis direction. The mounting bracket 210 includes a connecting bracket 211 connected to the output shaft of the X-axis moving module 120 and a fixing bracket 212 disposed on the connecting bracket 211. The connecting bracket 211 can be defined as a vertically mounted stand on one side of the X-axis moving module 120 along the Y-axis direction, and the fixing bracket 212 can be defined as a horizontally mounted stand at the lower end of the stand. The spray gun 200 includes a nozzle 220, a conduit 230 communicating with the nozzle 220 to deliver lubricant to the nozzle 220, a flow control valve 240 disposed on the conduit 230, and a valve control mechanism 250 for controlling the flow control valve 240.

[0045] In the illustrated embodiment, the nozzle 220 is used to operate on both the upper mold A21 and the lower mold A22. Therefore, the nozzle 220 can be defined as including an upper mold nozzle 221 and a lower mold nozzle 222. The upper mold nozzle 221 and the lower mold nozzle 222 can be defined as an integral nozzle structure fused together, that is, an outlet facing the upper mold A21 is provided on a cavity 223 as the upper mold nozzle 221, and an outlet facing the lower mold A22 is provided on the cavity 223 as the lower mold nozzle 222. It should be understood that the nozzle 220 is not limited to the structure of the above embodiment. For example, in some embodiments, the upper mold nozzle 221 and the lower mold nozzle 222 can also be two independent nozzle structures, and the nozzle can also selectively operate only on the upper mold A21 or only on the lower mold A22.

[0046] The pipeline 230 is arranged on the fixing frame 212 along the X-axis direction. The pipeline 230 includes a lubricant pipeline 231 and an air blowing pipeline 232 arranged in parallel. The lubricant pipeline 231 and the air blowing pipeline 232 can be defined as being arranged in parallel along the Y-axis direction. The output ends of the lubricant pipeline 231 and the air blowing pipeline 232 are both connected to the nozzle 220, that is, the output ends of the lubricant pipeline 231 and the air blowing pipeline 232 are both connected to the upper mold nozzle 221 and the lower mold nozzle 222. The input end of the air blowing pipeline 232 is connected to pressurized gas, and the input end of the lubricant pipeline 231 is connected to lubricant. The flow control valve 240 includes a lubricant flow control valve 241 arranged at the lubricant pipeline 231 and an air flow control valve 242 arranged at the air blowing pipeline 232. In the illustrated embodiment, the input end of the lubricant line 231 is connected to graphite lubricant. During spraying, the graphite lubricant is atomized by mixing with air at the nozzle 220. Correspondingly, the air flow control valve 242 and the lubricant flow control valve 241 are configured to run parallel along the Y-axis and are respectively arranged on the lubricant line 231 and the air blowing line 232. The height of the air flow control valve 242 is higher than the height of the lubricant flow control valve 241.

[0047] The valve control mechanism 250 is used to sequentially control the opening of the air flow control valve 242 and the lubricant flow control valve 241, so that the nozzle 220 sequentially blows air onto the upper mold A21 and / or the lower mold A22 and sprays atomized graphite lubricant onto the upper mold A21 and / or the lower mold A22. In the specific control process, firstly, the valve control mechanism 250 controls the air flow control valve 242 to open or adjust the opening degree (opening angle) of the air flow control valve 242, so that the upper mold nozzle 221 and the lower mold nozzle 222 blow air onto the upper mold A21 and the lower mold A22 to remove oxide scale and other debris from the upper mold A21 and the lower mold A22; then, with the air flow control valve 242 open, the valve control mechanism 250 controls the lubricant flow control valve 241 to open or adjust the opening degree of the lubricant flow control valve 241, so that the graphite lubricant mixes with the air in the cavity 223 for atomization, thereby causing the upper mold nozzle 221 and the lower mold nozzle 222 to spray atomized graphite lubricant.

[0048] The valve control mechanism 250 includes a push handle 251 located above the air flow control valve 242 and the lubricant flow control valve 241, and a pressing unit. The pressing unit is mounted on the fixing frame 212 via a side plate 252. The lower end of the side plate 252 is connected to the fixing frame 212. The lower end of the side plate 252 is provided with a horizontal channel 252a through which the lubricant pipeline 231 and the air blowing pipeline 232 pass. The horizontal channel 252a extends through the side plate 252 along the X-axis. The upper end of the side plate 252 is also provided with a vertical channel 252b. The vertical channel 252b extends upward along the Z-axis through the upper surface of the side plate 252, and also extends through the side plate 252 along the X-axis. The pressing unit includes a primary pressing unit 253 for driving the pressing handle 251 downward to open the air flow control valve 242, and a secondary pressing unit 254 for driving the pressing handle 251 to continue downward to open the lubricant flow control valve 241. The primary downward pressing unit 253 includes a first vertical lifting part 253a disposed on a first surface of the side plate 252 away from the nozzle 220 along the X-axis direction, a fixed part 253b connected to the lifting shaft of the first vertical lifting part 253a, and a pressing height sensing unit 253c. The pressing height sensing unit 253c is used to sense the pressing height of the fixed part 253b. The pressing height sensing unit 253c corresponds to the opening degree of the air flow control valve 242. When the fixed part 253b reaches the pressing height sensing unit 253c, it indicates that the opening degree of the air flow control valve 242 has reached a set value. The pressing height sensing unit 253c sends a sensing signal to the control module, and the control module controls the first vertical lifting part 253a to pause its descent according to the sensing signal. The fixed part 253b can be defined as a fixed block. One end of the fixed block is connected to the lifting shaft of the first vertical lifting part 253a, and the other end passes through the vertical channel 252b along the X-axis direction. The secondary pressing unit 254 is a second vertical lifting part disposed on the fixed part 253b and connected to a pressing part 255 by its output shaft. The second vertical lifting part is located on the second surface of the side plate 252 opposite to the first surface, and the lifting shaft of the second vertical lifting part is vertically downward. The pressing part 255 can be defined as a pressing block, which is located above the pressing handle 251 or in contact with the top of the pressing handle 251 in the initial state.

[0049] In the illustrated embodiment, the valve control mechanism 250 further includes a pivot seat 256. One end of the pressing handle 251 is pivotally connected to the pivot seat 256 to be able to rotate vertically about the pivot axis, and the other end of the pressing handle 251 extends upward toward the pressing unit. The pressing handle 251 includes a pressure seat 251a and a slanted handle 251b. In the initial state, the lower surface of the pressure seat 251a is an inclined surface that is upward and inclined toward the pressing part 255. One end of the pressure seat 251a is pivotally connected to the pivot seat 256, and the other end is located above the air flow control valve 242 and the lubricant flow control valve 241. One end of the slanted handle 251b is connected to the end of the pressure seat 251a away from the pivot seat 256, and the other end is upward and gradually inclined toward the pressing part 255 and located below the pressing part 255 or in contact with the lower surface of the pressing part 255.

[0050] Please continue reading. Figure 6 The material handling mechanism 300 includes a material handling arm 3a arranged parallel to the pipeline 230, a material handling claw 3b disposed at the material handling end of the material handling arm 3a, and a drive unit 3c for driving the material handling claw 3b to clamp or release. The material handling arm 3a is disposed at the lower end of the fixing frame 212 and distributed along the X-axis direction, so that the material handling arm 3a is parallel to the lower part of the pipeline 230. The extension length of the material handling arm 3a towards the mold is shorter than the extension length of the pipeline 230, so that the material handling claw 3b is located between the nozzle 220 and the moving mechanism 100, and the horizontal distance between the material handling claw 3b and the nozzle 220 must satisfy the condition that when the nozzle 220 is operating, the material handling claw 3b is located outside the side of the upper mold A21 and the lower mold A22 facing the material handling claw 3b. This prevents the material handling claw 3b from interfering with the nozzle 220 when the nozzle 220 is operating. In the embodiment shown, the material handling mechanism 300 further includes a conveying unit 3d disposed below the material handling arm 3a (see figure 3d). Figure 2 The conveying unit 3d is used to convey product A1 taken out by the picking mechanism 300 to the next destination position.

[0058] The working principle of the mold spraying device in this embodiment is as follows:

[0059] (i) Material picking: After the mold is opened, the moving mechanism 100 drives the picking mechanism 300 to take out the product A1 from the mold and place it at the conveying unit 3d below, so that the conveying unit 3d will convey the product A1 taken out by the picking mechanism 300 to the next destination position.The specific control is as follows: (1) Move the picking claw 3b to directly above the inner hole A11: The control module controls the X-axis moving module 120 to drive the mounting frame 210 to move towards the mold, so that the picking arm 3a mounted on the mounting frame 210 drives the picking claw 3b to move directly above the product A1 and align with the inner hole A11 of the product A1; (2) Move the first gripper 325a and the second gripper 325b downward into the inner hole A11: The control module controls the Z-axis moving module to drive the X-axis moving module 120 downward, so as to indirectly drive the first gripper 325a and the second gripper 325b of the picking claw 3b to move downward into the inner hole A11; (3) Clamping product A1: The control module controls the output shaft 31c of the drive unit 3c to push the first pivot shaft 323 along the X-axis towards the picking claw 3b. The first inclined rods 3282a and 3282b of the first pivot connecting rod 328a and the second pivot connecting rod 328b, which are pivotally connected to the first pivot shaft 323, move towards the picking claw 3b, and drive the second inclined rods 3283a and 3283b of the first pivot connecting rod 328a and the second pivot connecting rod 328b to rotate around the second pivot shaft 324a and 324b to an open state. The first clamping seat 326a and the second clamping seat 326b are connected to the second inclined rods 3283a and 3283b via the third pivot shaft 3292. The pivot holes 3284b and 3284b are pivoted, allowing the first clamp 326a and the second clamp 326b to move linearly along the Y-axis under the cooperation of the second elongated pivot holes 3284b and 3284b, the third pivot shaft 3292, and the second pivot hole 3291. That is, when the two second inclined rods 3283a and 3283b are opened, the first clamp 326a and the second clamp 326b open along the Y-axis (even if the top plate C1 and the bottom plate C2 are both opened along the Y-axis). The first clamp 326a and the second clamp 326b drive the first clamping finger 325a and the second clamping finger 325b to open along the Y-axis. The opened first clamping finger 325a and the second clamping finger 325b abut against the... (3) The two opposite holes of the inner hole A11 are used to clamp the product A1; (4) The picking claw 3b is reset upward along the Z-axis to the position directly above the product A1; (5) The picking claw 3b is reset along the X-axis to the position above the picking unit; (6) The control module controls the output shaft 31c of the drive unit 3c to reset along the X-axis, and the output shaft 31c of the drive unit 3c pulls the first pivot shaft 323 so that the first gripper 32a and the second gripper 32b are retracted and reset along the Y-axis, thereby causing the product A1 to disengage from the first gripper 32a and the second gripper 32b and fall naturally to the conveying unit 3d, and the conveying unit 3d conveys the product A1 to the next destination position.

[0060] (ii) Spraying: Control the opening of the air flow control valve 242 so that the upper mold nozzle 221 and the lower mold nozzle 222 blow air onto the upper mold A21 and the lower mold A22 respectively, thereby removing the debris at the upper mold A21 and the lower mold A22; control the opening of the lubricant flow control valve 241 so that the graphite ink mixes with the air at the nozzle 220 to form atomized graphite lubricant, thereby spraying atomized graphite lubricant onto the upper mold A21 and the lower mold A22 respectively by the upper mold nozzle 221 and the lower mold nozzle 222. The specific control is as follows: (1) The control module controls the X-axis moving module 120 to drive the nozzle 220 to move between the upper mold A21 and the lower mold A22; (2) The control module controls the pressing unit to press the pressing handle 251, and the pressing handle 251 presses the higher air flow control valve 242 first to open the blowing passage; (3) After step (2) or simultaneously with step (2), the control module controls the X-axis moving module 120, the Y-axis moving module 130 and / or the Z-axis moving module 110 to blow air between the upper mold A21 and the lower mold A22 to remove the debris according to a predetermined trajectory; (4) After the debris is removed, the control module controls the X-axis moving module 120, the Y-axis moving module 130 and / or the Z-axis moving module 110 to blow air between the upper mold A21 and the lower mold A22 to remove the debris. The module continues to control the pressing unit to press the pressing handle 251, and the pressing handle 251 presses the air flow control valve 242 and the lubricant flow control valve 241 to move down, so as to open the air blowing passage and the lubricant passage at the same time; (5) The control module controls the X-axis moving module 120, Y-axis moving module 130 and / or Z-axis moving module 110 to move in the corresponding direction according to the predetermined trajectory, so that the upper mold nozzle 221 and the lower mold nozzle 222 spray atomized graphite lubricant onto the upper mold A21 and the lower mold A22 respectively according to the predetermined trajectory; (6) The control module controls the nozzle to reset in preparation for the next spraying.

[0061] Compared with the prior art, the mold spraying device of the present invention has the following effects: (1) The air blowing pipeline and the lubricant pipeline are both connected to the nozzle, and the air flow control valve is opened to blow air to remove the debris at the upper mold and / or lower mold. Then, the air flow control valve and the lubricant flow control valve are controlled at the same time to make the lubricant and air at the nozzle mix to form atomized lubricant. This not only cleans the upper mold and / or lower mold before lubrication, so that the upper mold and / or lower mold are more comprehensively sprayed and lubricated, but also makes the air and lubricant mix to play an atomization role, and the atomized lubricant... (1) The lubricant volume is larger, which saves more lubricant; (2) The material taking mechanism and the spray gun are set together on the moving mechanism. Through one control module and one moving mechanism, the material taking, blowing and lubrication operations can be realized in sequence, saving manufacturing costs and reducing equipment volume; (3) The opening of the blowing flow control valve and the lubricant flow control valve are precisely controlled by the valve control mechanism to achieve full mixing of lubricant and air and improve the quality of atomized lubricant; Through the designed upper mold nozzle and lower mold nozzle, and the moving mechanism controls the upper mold nozzle and lower mold nozzle to move and spray according to the predetermined trajectory. The coating makes the spraying area more comprehensive and the spraying more uniform, solving the problems of lubricant accumulation and waste, and spraying dead corners caused by uneven spraying in traditional technology; (4) Compared with the traditional material picking claw structure that opens and closes around a pivot point (the traditional material picking claw structure opens in the shape of a "human"), the material picking claw of the mold spraying device of the present invention uses a first clamp and a second clamp with a specific structure, and a first pivot connecting rod and a second pivot connecting rod with a specific structure, so that the first clamp and the second clamp are pivotally connected through the first pivot connecting rod and the second pivot connecting rod, while driving the first clamp finger and the first clamp finger. The second gripper moves in a straight line in opposite directions, remaining parallel to each other when opening and closing. When opening, the parallel distance between the first and second grippers increases, and when closing, the parallel distance between the first and second grippers decreases. This increases the contact area between the first and second grippers and the two straight walls of the inner hole, ensuring clamping force. When closing, no part of the two straight first and second grippers will contact any wall of the inner hole, solving the problem of the product being unable to smoothly detach from the first and second grippers when they interfere with the product during closing.

[0062] The above embodiments merely illustrate preferred implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention should be determined by the appended claims.
