Description

Technical Field

[0001] This utility model relates to the field of lock manufacturing technology, and in particular to an automatic spraying device for die casting lock cylinders. Background Technology

[0002] Lock cylinder die casting is a high-precision forming process for the metal substrate of lock cylinders. It belongs to the category of cold chamber die casting technology. The core is to use a die casting machine to press molten metal into a pre-made lock cylinder mold cavity under high pressure and high speed. After the molten metal cools and solidifies rapidly in the mold, the mold is opened and the lock cylinder blank is removed. It is then processed into the final lock cylinder product. The lock cylinder blank process requires no air holes and complete cavity forming. The mold must maintain a smooth surface for a long time to ensure the forming quality. Therefore, an automatic spraying device for lock cylinder die casting is needed to accurately and evenly spray a release agent on the surface of the die casting mold before the lock cylinder metal is pressed into the mold, thereby ensuring that the lock cylinder blank can be successfully demolded.

[0003] In early lock cylinder die-casting production, the release agent spraying consisted of a manual spray gun and a support. The manual spray gun was held by the operator, who controlled the spraying of the release agent by pressing a trigger. The support was used to temporarily fix the position of the spray gun. Because manual operation relied on the operator's experience, the thickness of the release agent coating in different areas of the mold was inconsistent, resulting in scratches on the lock cylinder blank. To solve the above problems, existing automatic spraying devices for lock cylinder die-casting have introduced automated structural improvements, using a multi-degree-of-freedom robotic arm to replace manual hand operation. Through preset programs, the nozzle is accurately positioned, solving the problems of spraying position deviation and coating thickness. However, in actual use, because the nozzle is fixed by bolts, it cannot be replaced quickly when cleaning or due to wear, affecting work efficiency and failing to meet the needs of users.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1 , Figure 3 and Figure 4 An embodiment of this utility model is provided: an automatic spraying device for lock cylinder die casting, including a base 1, which is the support component of the entire device. A robotic arm 2 is fixedly connected to the top right side of the base 1. The robotic arm 2 can preset a motion trajectory according to the cavity position of the lock cylinder mold. A connecting shell 3 is fixedly connected to one end of the robotic arm 2. Quick release mechanisms 4 are provided on the left and right sides of the connecting shell 3. A collecting mechanism 5 is provided at the bottom of the connecting shell 3. The quick-release mechanism 4 includes two sleeves 401. One side of each sleeve 401 is aligned with the main release agent pipe of the connecting shell 3, and the other side provides guidance for the installation of the main nozzle 404. The adjacent sides of the two sleeves 401 are respectively connected to the upper middle part of the left and right sides of the connecting shell 3. Rotating covers 402 are rotatably connected to the opposite sides of the two sleeves 401. When the rotating covers 402 rotate, they cause the limiting blocks 406 to disengage from or engage with the inner side of the locking blocks 405. This, in conjunction with the limiting grooves 403, achieves axial limiting and circumferential fixing of the main nozzle 404. Limiting grooves 403 are provided on both sides of the inner walls of the two sleeves 401 and the rotating covers 402. The limiting grooves 403 serve as sliding guide channels for the locking blocks 405 of the main nozzle 404, limiting the radial displacement of the main nozzle 404. The inner walls of the two rotating covers 402 are slidably connected to... There is a main nozzle 404, which is the spraying component for the release agent. The front and rear ends of the two main nozzles 404 are fixedly connected to the outer walls of adjacent sides. The outer walls of multiple locking blocks 405 are slidably connected to the inner walls of the corresponding limiting grooves 403. The left and right ends of the two rotating covers 402 are fixedly connected to the adjacent sides. When the rotating cover 402 returns to its original position, the limiting block 406 slides into the groove on the inner side of the locking block 405, restricting the locking block 405 from sliding along the axial direction of the limiting groove 403, thereby locking the main nozzle 404. The outer walls of multiple limiting blocks 406 are slidably connected to the inner side of the corresponding locking block 405. An angle fixing component 407 is provided on the top of the outer wall of the two sleeves 401. The outer walls of the two main nozzles 404 are provided with auxiliary spraying components 408. The angle fixing assembly 407 includes two fixing plates 4071, which serve as sliding guides for the slide rods 4072. The bottoms of the two fixing plates 4071 are fixedly connected to the top of the outer wall of the corresponding sleeves 401. Slide rods 4072 are slidably connected to the inner walls of both fixing plates 4071. The slide rods 4072 are inserted into the limiting holes of the fixing plate 4075 to lock the angle of the rotating cover 402, preventing the rotating cover 402 from rotating in the unlocked state. Pull plates 4073 are fixedly connected to the outer walls of the two slide rods 4072 on opposite sides. Pulling the pull plates 4073 causes the slide rods 4072 to slide. Springs 4074 are fitted on the outer wall of the slide bar 4072. When unlocking, the springs 4074 are compressed. After the pull plate 4073 is released, the springs 4074 return to their original position and automatically push the slide bar 4072 to lock again. One end of each of the two springs 4074 is fixedly connected to one side of the corresponding pull plate 4073, and the other end of each of the two springs 4074 is fixedly connected to one side of the corresponding fixing piece 4071. Fixing pieces 4075 are fixedly connected to the top of the outer wall of each of the two rotating covers 402. Fixing pieces 4075 lock and unlock the angle between the rotating cover 402 and the sleeve 401 by inserting and releasing the slide bar 4072. The auxiliary spraying assembly 408 includes multiple connecting arms 4081, which serve as mounting brackets for the auxiliary spray heads 4083. One side of each connecting arm 4081 is fixedly connected to one side of the outer wall of a corresponding main spray head 404. A rotating cylinder 4082 is rotatably connected to the inner side of each connecting arm 4081, providing a rotation axis for the auxiliary spray heads 4083. The outer walls of each rotating cylinder 4082 are rotatably connected to the auxiliary spray heads 4083, which are used to fill in the spraying dead zones of the main spray head 404. A flexible hose 4084 connects to one side of the outer wall of each auxiliary spray head 4083. The flexible hose 4084 ensures that when the main spray head 404 supplies liquid, the release agent can be synchronously delivered to the auxiliary spray heads 4083, preventing supply issues caused by angle adjustments. Interrupted, the other ends of multiple hoses 4084 are respectively connected to the outer wall of the corresponding main nozzle 404. Multiple positioning holes 4085 are opened on the top of multiple connecting arms 4081. The positioning holes 4085 are used for the insertion of positioning pins 4086 to fix the swing angle of the auxiliary nozzle 4083. The top of multiple connecting arms 4081 is provided with positioning pins 4086. After adjusting the angle of the auxiliary nozzle 4083, the positioning pins 4086 are inserted downward into the corresponding positioning holes 4085. The protrusions are locked into the grooves on the outer wall of the rotating cylinder 4082, restricting the rotation of the rotating cylinder 4082, thereby locking the angle of the auxiliary nozzle 4083. The bottom of multiple positioning pins 4086 passes through the top of the corresponding connecting arm 4081 and slides through the inner wall of the rotating cylinder 4082. Specifically, when the nozzle becomes clogged or worn and the main nozzle 404 needs to be replaced, pull the pull plate 4073 to make the slide rod 4072 slide along the fixing plate 4071, while simultaneously compressing the spring 4074, causing the slide rod 4072 to disengage from the inner hole of the fixing plate 4075, thereby releasing the angle lock between the rotating cover 402 and the sleeve 401. Then, rotate the rotating cover 402 ninety degrees, causing the inner wall limiting block 406 to slide out from the inside of the locking blocks 405 on both sides of the main nozzle 404. At this time, the rotating cover 402 and the limiting groove 403 of the sleeve 401 are aligned, and the main nozzle 404 can be axially slid out along the limiting groove 403 through the outer wall locking block 405, completing the disassembly operation. When installing a new nozzle, the operation is reversed. After the locking block 405 resets along the limiting groove 403, the rotating cover 402 returns to its original position, allowing the limiting block 406 to re-engage inside the locking block 405. After releasing the pull plate 4073, the spring 4074 resets, pushing the slide rod 4072 into the fixing plate 4075 to achieve angle locking. The auxiliary nozzle 4083 can swing around the rotating cylinder 4082 as the axis to adjust the angle, thereby adapting to the deep cavity and corner area of ​​the lock core mold and avoiding the problem of limited coverage of a single nozzle. By inserting the positioning pin 4086 into different positioning holes 4085, the angle can be locked. The auxiliary nozzle 4083, in conjunction with the main nozzle 404, can expand the spraying area. The hose 4084 can ensure the stable transmission of the release agent and avoid interruption of liquid supply due to angle adjustment.

[0019] Reference Figure 1 , Figure 2 and Figure 5 The collection mechanism 5 includes a fixed pipe 502, which conducts the mist-like release agent adsorbed by the collection hood 501 to a connecting pipe 503. The top of the fixed pipe 502 is connected to the bottom of the connecting shell 3. The lower middle parts of the left and right sides of the connecting shell 3 are connected to the collection hood 501, which expands the negative pressure adsorption range. The bottom of the fixed pipe 502 is fixedly connected to the connecting pipe 503, which is used to transport the mist-like release agent conducted by the fixed pipe 502 and the negative pressure to the centrifugal fan 504. The top of the base 1 A centrifugal fan 504 is fixedly connected to the front left side. The centrifugal fan 504 generates negative pressure to drive adsorption, and at the same time pressurizes and transports the adsorbed atomized release agent to the collection tank 505. The other end of the connecting pipe 503 is connected to the right end of the centrifugal fan 504. The collection tank 505 is fixedly connected to the rear left side of the top of the base 1. The collection tank 505 is a gas-liquid separation and storage container for the escaped release agent. The other end of the centrifugal fan 504 is connected to the front side of the outer wall of the collection tank 505. A separation component is installed inside the collection tank 505. 506. A discharge assembly 507 is provided on the left side of the outer wall of the collection tank 505; the separation assembly 506 includes a baffle 5061. After the atomized release agent impacts the baffle 5061, it condenses into a liquid state and drips to the bottom of the collection tank 505 under the action of gravity. The front end of the baffle 5061 is fixedly connected to the middle of the front side of the inner wall of the collection tank 505. Umbrella-shaped separation plates 5062 are fixedly connected to both the upper and lower sides of the inner wall of the collection tank 505. A small amount of atomized release agent that is not completely condensed by the baffle 5061 continues to rise and is separated by the umbrella-shaped separation plates 5062. 062 Interception; Discharge assembly 507 includes a drain pipe 5071, which is used to discharge the liquid release agent stored in the collection tank 505. The right end of the drain pipe 5071 is connected to the bottom left side of the outer wall of the collection tank 505. A filter screen 5072 is fixedly connected to the right side of the inner wall of the drain pipe 5071. The filter screen 5072 is used to filter impurities in the liquid release agent. A valve 5073 is provided on the outer wall of the drain pipe 5071. The opening and closing of the drain pipe 5071 is controlled by rotating the handle of the valve 5073. Specifically, after the release agent is sprayed from the nozzle, it diffuses in a water mist. At this time, the centrifugal fan 504 is started. The negative pressure generated by the fan is conducted through the connecting pipe 503 to the fixed pipe 502, forming a negative pressure adsorption zone at the collection hood 501 in the lower middle part of the left and right sides of the connecting shell 3. This adsorbs the misty release agent that escapes during the spraying process, preventing it from spreading into the workshop environment. The misty release agent enters the centrifugal fan 504 with the airflow through the fixed pipe 502 and the connecting pipe 503, and is then transported by the fan to the collection tank 505. The outlet of the centrifugal fan 504 is directly above the collection tank. The escaping mist-like release agent is sprayed onto the baffle 5061 on the front side of the inner wall of the collection tank 505. After condensing into water droplets, it falls to the bottom of the tank. A small amount of mist-like release agent that has not completely condensed continues to rise and is intercepted by the umbrella-shaped separation plate 5062. The mist droplets condense into liquid droplets here and drip down the inclined surface of the umbrella-shaped plate to the bottom of the tank. When it is necessary to recover the release agent, the valve 5073 on the outer wall of the drain pipe 5071 is opened. The liquid release agent at the bottom of the tank will flow out through the drain pipe 5071 and can be filtered out by the filter screen 5072 to remove impurities in the release agent.

[0020] Reference Figure 1 , Figure 2 and Figure 3 The centrifugal fan 504 has reinforcing blocks 6 fixedly connected to the bottom of its outer walls. The reinforcing blocks 6 disperse and transmit the vibration generated by the fan during operation to the base 1. The bottom of the multiple reinforcing blocks 6 is fixedly connected to the top left side of the base 1. The inner walls of the two sleeves 401 are fixedly connected to sealing gaskets 7. The positions of the two sealing gaskets 7 are respectively matched with the positions of the adjacent sides of the corresponding main nozzles 404. When the main nozzles 404 are inserted, the sealing gaskets 7 are squeezed and elastically deformed, filling the gap between the main nozzles 404 and the inner walls of the sleeves 401 to form a sealing surface. Specifically, the centrifugal fan 504 is fixed to the top of the base 1. After long-term operation, the fan's own vibration will cause it to loosen and shift. The reinforcing block 6 disperses the vibration generated by the fan during operation to the base 1, preventing vibration concentration from causing loosening. At the same time, the reinforcing block 6 can limit the fan's horizontal displacement. When the main nozzle 404 passes through the insert sleeve 401, one side of the main nozzle 404 will squeeze the sealing gasket 7, causing the sealing gasket 7 to undergo elastic deformation, filling the gap between the main nozzle 404 and the inner wall of the sleeve 401 to form a sealing surface, preventing the release agent from leaking from the connection gap.

[0021] Working principle: When the main nozzle 404 needs to be replaced due to blockage or wear, the sliding rod 4072 slides along the fixing plate 4071 by pulling the pull plate 4073. Simultaneously, the spring 4074 is compressed, causing the sliding rod 4072 to disengage from the inner hole of the fixing plate 4075, releasing the angle lock between the rotating cover 402 and the sleeve 401. Rotating the rotating cover 402 ninety degrees causes the inner wall limiting block 406 to slide out from the inside of the locking blocks 405 on both sides of the main nozzle 404. At this time, the rotating cover 402 aligns with the limiting groove 403 of the sleeve 401, and the main nozzle 404 slides axially along the limiting groove 403 via the outer wall locking block 405. The nozzle is pulled out to complete the disassembly. When installing a new nozzle, the operation is reversed. After the locking block 405 is reset along the limiting groove 403, the rotating cover 402 returns to its original position so that the limiting block 406 is re-locked into the inner side of the locking block 405. After releasing the pull plate 4073, the spring 4074 resets and pushes the slide rod 4072 to insert the fixing piece 4075 to achieve angle locking. The auxiliary nozzle 4083 can swing around the rotating drum 4082 as the axis to adjust the angle, which is suitable for the deep cavity and corner area of ​​the lock core mold, avoiding the limited coverage of a single nozzle. The positioning pin 4086 can be inserted into different positioning holes 4085 to lock the angle, which, together with the main nozzle 404, expands the spraying area. Furthermore, when the release agent is sprayed out through the nozzle, it diffuses in a water mist. The centrifugal fan 504 is activated, and the negative pressure generated by the fan is transmitted through the connecting pipe 503 to the fixed pipe 502. Then, the collection hoods 501 on the lower left and right sides of the connecting shell 3 form a negative pressure adsorption zone, absorbing the mist-like release agent that escapes during spraying and preventing it from spreading into the workshop environment. The mist-like release agent, carried by the airflow, enters the centrifugal fan 504 through the fixed pipe 502 and connecting pipe 503, and is then transported by the fan to the collection tank 505. The outlet of the centrifugal fan 504 is directly above the... The diffused mold release agent sprayed onto the baffle 5061 on the front side of the inner wall of the collection tank 505 condenses into water droplets and falls to the bottom of the tank. A small amount of incompletely condensed mold release agent continues to rise and is intercepted by the umbrella-shaped separation plate 5062, causing the droplets to condense into liquid droplets and drip down the inclined surface of the umbrella-shaped plate to the bottom of the tank. When it is necessary to recover the mold release agent, the valve 5073 on the outer wall of the drain pipe 5071 is opened, and the liquid mold release agent at the bottom of the tank will flow out through the drain pipe 5071. The impurities in the mold release agent can be filtered out by the filter screen 5072.
