Description

Technical Field

[0001] This utility model relates to the field of mold cleaning technology, specifically to an automated cleaning device for flat molds. Background Technology

[0002] Silicone rubber products are typically vulcanized or injection molded using aluminum or steel molds. During repeated molding processes, the molds may experience oxidation, clogging, and residual impurities. During processing, transportation, and storage, the mold surface may accumulate contaminants such as oil, iron filings, and dust. These contaminants not only affect the mold's appearance but may also damage its precision and performance. Cleaning can effectively remove these contaminants and restore the mold to its original condition.

[0003] Currently, existing cleaning methods are divided into cleaning methods that do not disassemble the mold (sandblasting, dry ice cleaning, and cleaning using a handheld laser cleaning machine) and cleaning methods that disassemble the mold (sandblasting, dry ice cleaning, ultrasonic cleaning, electrolytic cleaning, and cleaning using offline laser cleaning equipment). When using sandblasting, the cost is high, the cleaning is not thorough, and it is easy to damage the parts. When using dry ice cleaning, dry ice is easy to evaporate, inconvenient to store, noisy, and requires wearing protective equipment such as protective masks. When using ultrasonic cleaning, it can only clean oil or rust, the cleaning noise is high, and the applicable range is small. When using electrolytic cleaning, it is easy to damage the surface protective layer, and corrosion prevention is required after cleaning. When using handheld laser cleaning, the large fluctuations in laser focal length result in uneven cleaning effects, easily damaging the mold and leading to low cleaning efficiency. It also requires highly skilled operators. Offline laser cleaning equipment requires waiting for the mold to cool down after production has stopped before removing it from the production equipment and placing it on the cleaning equipment. After cleaning, it needs to be reloaded onto the production equipment and then allowed to heat up before resuming production. These different methods of mold cleaning result in low efficiency, poor cleaning effects, and a high risk of mold damage.

[0004] An automated cleaning device for planar molds is proposed to address the problems mentioned above. Utility Model Content

[0018] Compared with the prior art, the beneficial effects of this utility model are: This automated planar mold cleaning equipment will not pollute the environment, requires no consumables, is highly efficient, and will not damage the surface of the workpiece. It can perform mold cleaning in scenarios where the mold is disassembled or not. It can realize fully automatic upper and lower mold opening structure, left and right mold opening mechanism, single-layer mold, and multi-layer mold cleaning. It uses laser cleaning of molds, does not damage the substrate, and repeated cleaning does not affect the mold's accuracy. The specific details are as follows:

[0019] 1. During mold cleaning, a laser cleaning head is used. During the cleaning process, a servo motor can be activated to rotate the output end of the first gear commutator, which in turn rotates the output end of the second gear commutator via the first connecting shaft. This causes four screw jacks to move, moving the lifting platform. The height of the lifting platform can be adjusted, thus adjusting the height of the laser cleaning head. Then, the first linear electric slide rail can be activated to move the second linear electric slide rail, allowing adjustment of the laser cleaning head's left-right position. Simultaneously, the second linear electric slide rail can be activated to move the support frame, allowing the laser cleaning head to move back and forth, adjusting its position. Finally, a drive motor can be activated to rotate the rotating rod. The laser cleaning head angle is adjustable and flexible. A controller is installed on the frame to enable human-machine interaction. After the handheld human-machine interface is used to align the mold on the equipment with the reference position and focal length, one-button automatic start is achieved. The control system automatically executes the XYZR axis coordinated movement to achieve fully automatic cleaning of single-sided and multi-sided molds. After cleaning, the XYZR axis automatically returns to the equipment's origin position. It does not cause environmental pollution, requires no consumables, is highly efficient, and does not damage the workpiece surface. It can perform mold cleaning in scenarios where the mold does not need to be disassembled or the mold needs to be disassembled. It can achieve fully automatic cleaning of top and bottom opening mold structures, left and right opening mold mechanisms, single-layer molds, and multi-layer molds. Using laser to clean molds does not damage the substrate, and repeated cleaning does not affect the mold's accuracy.

[0020] 2. The removal of the baffle facilitates the inspection and maintenance of internal components. When removing the baffle, the operator can use their palm to push against the support rod and pull the U-shaped frame. This movement compresses the telescopic spring, causing the positioning frame to move away from the positioning slot on the mounting plate. Rotating the rotating rod then misaligns the positioning frame with the positioning slot, preventing it from obstructing the baffle. The baffle, no longer obstructing the view, can then be removed. When installing the baffle, after placement, pulling and rotating the U-shaped frame compresses the telescopic spring, aligning the positioning frame with the positioning slot on the mounting plate. Releasing the U-shaped frame allows the positioning frame to insert into the positioning slot under the action of the telescopic spring, which is then compressed, ensuring reliable baffle installation. This facilitates easy installation and removal of the baffle, enhancing its practicality and subsequent maintenance. Attached Figure Description

[0031] Working principle: Before using this type of automated cleaning equipment for flat molds, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 6 As shown, during mold cleaning, the laser cleaning head 119 cleans the mold. During the cleaning process, the servo motor 103 can be activated to drive the output end of the first gear commutator 104 to rotate, which in turn drives the output end of the second gear commutator 106 to rotate via the first connecting shaft 105. This causes the four screw jacks 108 to move, moving the lifting platform 109. The height of the lifting platform 109 can be adjusted, thus adjusting the height of the laser cleaning head 119. Then, the first linear electric slide rail 112 can be activated to move the second linear electric slide rail 113, allowing adjustment of the left-right position of the laser cleaning head 119. Simultaneously, the second linear electric slide rail 113 can be activated to move the support frame 116, allowing the laser cleaning head 119 to move back and forth, thus adjusting the cleaning position. The machine is equipped with a controller that allows for human-machine interaction. The controller enables one-button automatic start-up of the mold on the machine by using a handheld human-machine interface to align the mold's reference position and focal length. The control system automatically executes the XYZR axis movements to achieve fully automatic cleaning of single-sided and multi-sided molds. After cleaning, the XYZR axis automatically returns to its original position. This system is environmentally friendly, requires no consumables, is highly efficient, and does not damage the workpiece surface. It can perform mold cleaning in scenarios where the mold is disassembled or not. It supports fully automatic top-and-bottom mold opening structures, left-and-right mold opening mechanisms, and single-layer and multi-layer mold cleaning. Laser cleaning of the mold does not damage the substrate, and repeated cleaning does not affect the mold's precision.

[0032] Removing the baffle 1011 facilitates the inspection and maintenance of the internal components of the frame 1. When removing the baffle 1011, the operator can use their palm to press against the support rod 208 and pull the U-shaped frame 207 to move. The movement of the U-shaped frame 207 compresses the telescopic spring 203, causing the positioning frame 202 to move, thus disengaging it from the positioning groove 206 on the mounting plate 205. Then, rotating the rotating rod 201 displaces the positioning frame 202 from the positioning groove 206, preventing the positioning frame 202 from obstructing the baffle 1011. With the baffle 1011 no longer in a limiting position, it can be removed. When installing the baffle 1011, after the baffle 1011 is placed, the U-shaped frame 207 is pulled and rotated, which compresses the telescopic spring 203. Then, the positioning frame 202 is aligned with the positioning groove 206 on the mounting plate 205. After that, the U-shaped frame 207 can be released, and under the action of the telescopic spring 203, the positioning frame 202 is inserted into the positioning groove 206. At this time, the telescopic spring 203 is in a compressed state, which can ensure the reliability of the installation of the baffle 1011. This makes it easier for the staff to disassemble and assemble the baffle 1011, facilitates subsequent inspection and maintenance, and improves its practicality.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
