Description

Technical Field

[0001] This utility model belongs to the field of mold cleaning technology, and specifically relates to a mold cleaning device. Background Technology

[0002] In the process of mold manufacturing and use, mold cleaning and maintenance play a crucial role in ensuring product quality and extending mold life. Traditional mold cleaning devices often suffer from incomplete cleaning and low efficiency. Existing mold cleaning devices only have nozzles in a single direction, making it difficult to thoroughly clean all surfaces of the mold. This is especially true for molds with complex structures and multiple surfaces, easily leading to cleaning dead zones, resulting in dirt residue and affecting the mold's subsequent performance. Moreover, existing devices are insufficient in post-cleaning treatment; water stains on the mold surface are difficult to remove quickly, usually requiring an additional drying process. This not only increases cleaning time and cost but may also cause problems such as rust and corrosion due to water residue. Utility Model Content

[0003] The purpose of this invention is to provide a mold cleaning device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a mold cleaning device, comprising:

[0005] The mold cleaning tank has, from top to bottom, an end face cleaning square tube, a side cleaning square tube, and a bottom cleaning square tube for high-pressure cleaning and water stain blowing treatment of the mold. One end of the end face cleaning square tube, the side cleaning square tube, and the bottom cleaning square tube is equipped with an electric three-way valve that switches between high-pressure water supply cleaning and high-pressure air blowing water stain treatment through a multi-channel pipe fitting.

[0006] The mold cleaning tank extends outward from one side to form an extended unloading platform with a through groove for loading and unloading molds. Inside the mold cleaning tank and the extended unloading platform, there is a sliding placement frame for cleaning and loading / unloading the molds by moving them laterally. Inside the placement frame, there is a pneumatic lifting platform for lifting the end of the molds it is placed on.

[0007] Preferably, the end face cleaning square tube is provided with a high-pressure cleaning head at an angle and evenly distributed on the inner side. The angled spraying method can increase the contact area and impact force between the water flow and the mold surface, and more effectively remove stubborn dirt from the mold end face. The side cleaning square tube is provided with three side high-pressure cleaning water spray holes at an evenly distributed inner side. The side high-pressure cleaning water spray holes can make the high-pressure water evenly cover the side of the mold, ensuring that every part of the side of the mold can be cleaned.

[0008] Preferably, the bottom cleaning square tube has horizontally evenly arranged water pipes on its inner side, and the end faces of the horizontal water pipes are evenly provided with cleaning spray holes for upward high-pressure water spraying. Support blocks are evenly arranged between the horizontal water pipes to support and suspend the pneumatic lifting platform as it enters the bottom of the mold cleaning tank. An ultrasonic transducer, fixedly connected to the support block and used for ultrasonic cleaning of the mold, is located inside the support block at the position corresponding to the mold cleaning tank. The ultrasonic vibration cleaning of the mold by the cleaning water allows high-pressure water to be sprayed upwards from the bottom of the mold, effectively cleaning the dirt on the bottom of the mold. Due to the even distribution of the horizontal water pipes and cleaning spray holes, all areas of the mold bottom can be thoroughly cleaned, providing support and suspension when the pneumatic lifting platform enters the bottom of the mold cleaning tank.

[0009] Preferably, multiple branch pipes of the multi-channel pipe fitting are connected through one side of the end face cleaning square pipe, the side cleaning square pipe, and the bottom cleaning square pipe. One end of the electric three-way valve is connected to the multi-channel pipe fitting. The electric three-way valve can flexibly switch between the working modes of high-pressure water supply cleaning and high-pressure air blowing water stains.

[0010] Preferably, one end of the electric three-way valve is connected to a high-pressure air pump that generates high-pressure gas through a pipeline, and the other end of the electric three-way valve is connected to a high-pressure water pump that draws water from the external water tank and outputs high-pressure water through a pipeline. The high-pressure gas is delivered to each cleaning square tube through the electric three-way valve to quickly dry the water stains on the surface of the mold and avoid the problem of rust and corrosion of the mold due to water stain residue.

[0011] Preferably, both the mold cleaning tank and the extended unloading platform have lead screws rotating in the same direction on their inner side walls. One end of each lead screw is connected to a motor installed outside the mold cleaning tank. Each lead screw has a moving block with a limiting slider on one side. The moving block slides stably in cooperation with the guide grooves provided on the inner walls of the mold cleaning tank and the extended unloading platform through the limiting slider. By controlling the rotation direction and speed of the lead screw by the motor, the moving position and speed of the moving frame can be precisely controlled, so as to realize the accurate movement of the mold between the cleaning tank and the unloading platform.

[0012] Preferably, the top plate extending to both sides at the end of the movable frame is equipped with a lifting cylinder, and one end of the lifting cylinder is fixedly connected to the side of the pneumatic lifting platform for mold loading, unloading, and cleaning, thereby automating the mold loading, unloading, and cleaning process and improving work efficiency. A drain pipe is provided through the bottom of one side of the mold cleaning tank, which can promptly discharge the wastewater generated during the cleaning process and keep the cleaning tank clean. The inner side of the pneumatic lifting platform is welded to the outer frame by two intersecting metal rods, ensuring the safety and stability of the mold during lifting and cleaning.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This invention utilizes a three-dimensional layout of square tubes for cleaning the end faces, sides, and bottom, combined with a three-way electric valve to switch between high-pressure water and high-pressure air for simultaneous multi-face cleaning and rapid air-blowing drying of the mold. The design of the inclined high-pressure cleaning head at the end faces, the dual vertical water spray holes on the sides, and the horizontal water pipe with upward high-pressure spray from the bottom thoroughly removes stubborn dirt from all surfaces of the mold, avoiding cleaning dead zones. The linkage between the high-pressure air pump and the three-way electric valve quickly dries water stains after cleaning, eliminating the need for an additional drying process and effectively solving the problems of incomplete cleaning and water residue leading to mold corrosion caused by traditional devices.

[0015] The coordinated design of the screw-driven placement and moving frame and the pneumatic lifting platform enables fully automated operation of the mold cleaning process. The motor-driven screw moves the moving block precisely laterally, while the guide groove limiting structure ensures mold positioning accuracy. The lifting cylinder controls the vertical movement of the pneumatic lifting platform, automatically completing mold loading and unloading and precise docking at the cleaning station. The pneumatic lifting platform structure, with its cross-welded metal rods, enhances load-bearing stability, prevents mold displacement, significantly improves cleaning efficiency and quality, and reduces manual intervention, solving the technical pain points of inconvenient loading and unloading and large positioning errors associated with traditional equipment.

[0016] This invention combines ultrasonic vibration generated by an ultrasonic transducer with high-pressure water cleaning, increasing the contact area and impact force between the water flow and the mold surface. This more effectively removes stubborn dirt from the mold, reduces cleaning time, and improves cleaning efficiency, overcoming the problem of low cleaning efficiency in existing technologies. Compared with traditional manual cleaning methods, the mold cleaning machine uses advanced technologies based on ultrasonic vibration and electrolysis principles, enabling it to complete complex cleaning tasks in a short time and greatly improving work efficiency.

[0024] 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.

[0025] Please see Figure 1-6 This utility model provides a technical solution: a mold cleaning device, comprising:

[0026] The mold cleaning tank 1 has, from top to bottom, a three-section square tube for high-pressure cleaning and air-blowing of water stains on its inner side, including an end-face cleaning square tube 2, a side cleaning square tube 3, and a bottom cleaning square tube 4. The end-face cleaning square tube 2 is installed on the upper inner side of the mold cleaning tank 1, with one end connected to an electric three-way valve 5 via a multi-channel fitting 6. High-pressure cleaning heads 10, evenly distributed at an inclined angle, can perform high-pressure cleaning or air-blowing of water stains on the mold end face when high-pressure water or high-pressure air is input through the multi-channel fitting 6. The inclined design increases the contact area and impact force between the water or airflow and the mold end face, thus more effectively removing dirt and drying water stains.

[0027] Two side cleaning square tubes 3 are vertically installed inside the mold cleaning tank 1. One end is connected to an electric three-way valve 5 via a multi-channel fitting 6. High-pressure cleaning spray holes 11 are evenly arranged on their inner sides, allowing for simultaneous high-pressure cleaning of both sides of the mold when high-pressure water is input; when switching to high-pressure air, water stains on the sides are blown away. The two vertically arranged side cleaning square tubes 3 ensure that the sides of the mold are thoroughly and efficiently cleaned and dried.

[0028] The bottom cleaning square tube 4 is located at the bottom inner side of the mold cleaning tank 1, with one end connected to the multi-channel pipe fitting 6. Horizontal water pipes 12 are evenly distributed along its inner side, and each horizontal water pipe 12 has an upward high-pressure water spray hole 13 on its end face. When high-pressure water is input, the upward-sprayed high-pressure water cleans the bottom surface of the mold. Support blocks 14 are evenly arranged between the horizontal water pipes 12, providing support and suspension when the pneumatic lifting platform 9 enters the bottom of the mold cleaning tank 1, ensuring thorough cleaning of the mold bottom surface and preventing direct contact between the pneumatic lifting platform 9 and the bottom of the cleaning tank, thus avoiding damage.

[0029] The end face cleaning square tube 2, the side cleaning square tube 3, and the bottom cleaning square tube 4 are equipped with an electric three-way valve 5 that switches between high-pressure water supply cleaning and high-pressure air blowing water stains through a multi-channel pipe fitting 6.

[0030] Multiple branch pipes of the multi-channel fitting 6 are respectively connected to one side of the end face cleaning square pipe 2, the side cleaning square pipe 3, and the bottom cleaning square pipe 4, and one end of each branch pipe is connected to the electric three-way valve 5. Its function is to evenly distribute the high-pressure water or high-pressure air switched by the electric three-way valve 5 into each cleaning square pipe, ensuring that each cleaning square pipe can work simultaneously, so as to achieve synchronous cleaning or air-blowing drying of multiple sides of the mold.

[0031] An extended unloading platform 7 with a through slot extends outward from one side of the mold cleaning tank 1, connecting to the extended unloading platform 7 on one side of the mold cleaning tank 1. This platform provides an operating platform for loading and unloading molds, allowing operators to place molds on the pneumatic lifting platform 9 for loading or unloading after cleaning. It communicates with the interior of the mold cleaning tank 1, facilitating the movement of a movable frame 8 between them for mold transfer. The movable frame 8, which slides within the mold cleaning tank 1 and the extended unloading platform 7, allows for lateral movement of the cleaning molds for cleaning and unloading. Lifting cylinders 20 are installed on the top plates extending to both sides of the platform, with the pneumatic lifting platform 9 located inside. The placement and moving frame 8 is connected to the lead screw 17 via the moving block 19 on the lead screw 17. When the motor 18 drives the lead screw 17 to rotate, it can drive the placement and moving frame 8 to move laterally between the mold cleaning tank 1 and the extended unloading platform 7, thereby realizing the transfer of the mold before and after cleaning and the position adjustment during the cleaning process, ensuring that the mold can be accurately placed within the cleaning range of each cleaning square tube.

[0032] The inner side of the placement frame 8 is equipped with a pneumatic lifting platform 9 for raising and lowering the mold placement end. The pneumatic lifting platform 9 is installed inside the placement frame 8 and is fixedly connected to the top plate side of the placement frame 8 end via a lifting cylinder 20. When loading the mold, the lifting cylinder 20 pushes the pneumatic lifting platform 9 upward, raising the mold to a height where it aligns with the placement frame 8. When unloading, the lifting cylinder 20 pulls the pneumatic lifting platform 9 downward, lowering the mold from the placement frame 8 onto the extended unloading platform 7. During the cleaning process, it can support the mold and adjust its height via lifting to better accommodate the cleaning of each cleaning square tube.

[0033] High-pressure cleaning heads 10 are evenly and obliquely installed on the inner side of the end-face cleaning square tube 2. These high-pressure cleaning heads 10 are the actuators that directly perform high-pressure cleaning on the mold end face. When high-pressure water passes through the end-face cleaning square tube 2, it is sprayed onto the mold end face at an oblique angle, using the impact force of the water flow to remove dirt from the mold end face. The side cleaning square tube 3 has three high-pressure cleaning spray holes 11 evenly arranged on its inner side. When high-pressure water passes through the side cleaning square tube 3, it is sprayed out from these spray holes to clean the sides of the mold, effectively removing dirt from the sides of the mold.

[0034] The bottom cleaning square tube 4 has horizontally evenly arranged horizontal water pipes 12 on its inner side, and the end faces of the horizontal water pipes 12 are evenly provided with cleaning spray holes 13 for upward high-pressure water spraying. The horizontal water pipes 12 are evenly distributed horizontally on the inner side of the bottom cleaning square tube 4, and their end faces are provided with cleaning spray holes 13. They receive high-pressure water from the multi-channel fitting 6 into the bottom cleaning square tube 4, which is sprayed upward through the cleaning spray holes 13 to clean the bottom surface of the mold, ensuring that all parts of the bottom surface of the mold are cleaned. In addition, support blocks 14 are evenly arranged between the horizontal water pipes 12 to support and suspend the pneumatic lifting platform 9 when it enters the bottom of the mold cleaning tank 1. When the pneumatic lifting platform 9 enters the bottom of the mold cleaning tank 1, the support blocks 14 support and suspend the pneumatic lifting platform 9, so that the bottom surface of the mold is kept at a certain distance from the bottom of the cleaning tank. This is conducive to the flow of high-pressure water on the bottom surface of the mold, achieving comprehensive cleaning, while protecting the pneumatic lifting platform 9 from direct friction and damage to the bottom of the cleaning tank.

[0035] An ultrasonic transducer 22, fixed to the bottom of the support block 14 and located inside the mold cleaning tank 1, generates ultrasonic vibrations to clean the mold. The cleaning water then performs ultrasonic vibration cleaning on the mold. This transducer plays a crucial role in the mold cleaning process. The ultrasonic transducer 22 generates ultrasonic vibrations, which, in conjunction with the cleaning water, efficiently clean the mold using ultrasonic vibration. This cleaning method offers several significant advantages. First, when ultrasonic waves propagate in the cleaning water, they form alternating longitudinal waves, generating tens of thousands of tiny bubbles. These bubbles collapse under pressure in high-pressure areas and expand rapidly in low-pressure areas; this repeated process is called the "cavitation effect." The instantaneous high pressure generated by the cavitation effect can reach thousands of atmospheres, powerfully impacting the mold surface and thoroughly removing stubborn dirt, oil stains, and other impurities, greatly improving the cleaning effect and ensuring that every tiny corner of the mold is thoroughly cleaned, effectively compensating for the shortcomings of simple high-pressure water cleaning.

[0036] From a working principle perspective, the ultrasonic transducer 22 is an electromechanical energy conversion device. Its internal structure typically includes a piezoelectric ceramic element. When an external high-frequency AC signal is applied to the piezoelectric ceramic element, based on the piezoelectric effect, the piezoelectric ceramic will undergo mechanical deformation under the influence of the electric field, and the frequency of the deformation is consistent with the frequency of the applied electrical signal. In this mold cleaning device, by precisely controlling the frequency of the electrical signal input to the ultrasonic transducer 22, it can stably output ultrasonic waves of a specific frequency, generally in the range of 20kHz-100kHz. Ultrasonic waves in this frequency band have good applicability in the cleaning field.

[0037] In practical applications, common ultrasonic transducers suitable for this mold cleaning device include the HC-2000 model. The HC-2000 ultrasonic transducer boasts high conversion efficiency, effectively converting input electrical energy into ultrasonic mechanical energy, with an output power of up to 2000W, meeting the cleaning needs of molds of various sizes. Furthermore, it exhibits excellent stability and durability, adapting to prolonged, high-intensity working environments, providing a solid guarantee for the stable operation of the mold cleaning device.

[0038] Multiple branch pipes of the multi-channel pipe fitting 6 are connected to one side of the end face cleaning square pipe 2, the side cleaning square pipe 3 and the bottom cleaning square pipe 4. One end of the electric three-way valve 5 is connected to the multi-channel pipe fitting 6. One end of the electric three-way valve 5 is connected to a high-pressure air pump 15 that generates high-pressure gas through a pipe. The other end of the electric three-way valve 5 is connected to a high-pressure water pump 16 that draws water from the external water tank and outputs it as high-pressure water through a pipe.

[0039] The electric three-way valve 5, by controlling its passage switching, can deliver high-pressure water output from the high-pressure water pump 16 or high-pressure air output from the high-pressure air pump 15 to the multi-channel pipe fitting 6, and then distribute it to each cleaning square pipe, realizing the switching between two different operation modes: cleaning the mold and drying water stains by air blowing.

[0040] The high-pressure air pump 15 is connected to one end of the electric three-way valve 5 through a pipeline. Its function is to generate high-pressure gas. When the electric three-way valve 5 is switched to the passage connected to the high-pressure air pump 15, the high-pressure gas is delivered to each cleaning square tube through the electric three-way valve 5 and the multi-channel pipe fitting 6. This is used to quickly dry the residual water stains on the surface of the mold after cleaning and prevent the mold from rusting.

[0041] The high-pressure water pump 16 is connected to the other end of the electric three-way valve 5 via a pipe. It draws water from the external water tank and pressurizes it. When the electric three-way valve 5 switches to the passage connected to the high-pressure water pump 16, the high-pressure water is delivered to each cleaning square pipe through the electric three-way valve 5 and the multi-channel pipe fitting 6 for high-pressure cleaning of the mold. The impact force of the high-pressure water is used to remove dirt from the surface of the mold.

[0042] Both the mold cleaning tank 1 and the extended unloading platform 7 have lead screws 17 rotating in the same direction on their inner side walls. One end of the lead screw 17 is connected to a motor 18 installed outside the mold cleaning tank 1. Each lead screw 17 has a moving block 19 with a limiting slider on one side. The moving block 19 slides stably in cooperation with the guide groove provided on the inner wall of the mold cleaning tank 1 and the extended unloading platform 7 through the limiting slider.

[0043] One end of the lead screw 17 passes through the outside of the mold cleaning tank 1 and is connected to the motor 18 for transmission. A movable block 19 is provided on the lead screw 17. The movable block 19 engages with the guide grooves provided on the inner wall of the mold cleaning tank 1 and the extended unloading platform 7 via a limiting slider. When the motor 18 drives the lead screw 17 to rotate, the rotation of the lead screw 17 is converted into linear motion of the movable block 19, thereby driving the placement and moving frame 8 connected to the movable block 19 to move laterally between the mold cleaning tank 1 and the extended unloading platform 7, realizing the transfer of the mold before and after cleaning, as well as the position adjustment during the cleaning process.

[0044] The motor 18 provides power for the rotation of the lead screw 17. By controlling the forward and reverse rotation and the speed of the motor 18, the rotation direction and speed of the lead screw 17 can be precisely controlled, thereby accurately controlling the moving direction and speed of the placement moving frame 8, realizing the accurate movement of the mold between the cleaning tank and the unloading platform, and meeting different cleaning and unloading requirements.

[0045] A lifting cylinder 20 is installed on the top plate extending to both sides from the ends of the movable frame 8. One end of the lifting cylinder 20 is fixedly connected to the side of the pneumatic lifting platform 9 for mold loading, unloading, and cleaning. A drain pipe 21 is installed through the bottom of one side of the mold cleaning tank 1. Its function is to promptly drain the wastewater generated during the cleaning process from the mold cleaning tank 1, keeping the inside of the cleaning tank clean and preventing wastewater accumulation from affecting the cleaning effect and the normal operation of the equipment.

[0046] The inner side of the pneumatic lifting platform 9 is welded to the outer frame via two intersecting metal rods. One end of the lowering cylinder 20 is fixedly connected to the side of the pneumatic lifting platform 9. The lifting cylinder 20 controls the lifting of the pneumatic lifting platform 9 by controlling the extension and retraction of its piston rod. When loading the mold, the piston rod extends to push the pneumatic lifting platform 9 upward; when unloading, the piston rod retracts to pull the pneumatic lifting platform 9 downward, thereby realizing the vertical transfer of the mold between the placement moving frame 8 and the extended unloading platform 7, as well as adjusting the mold height during the cleaning process.

[0047] Specifically, in use, the mold is placed on the pneumatic lifting platform 9 of the extended unloading platform 7. The lifting cylinder 20 is activated, pushing the pneumatic lifting platform 9 upward to raise the mold to the appropriate height of the placement moving frame 8 for subsequent docking. At the same time, the motor 18 drives the lead screw 17 to start rotating. With the cooperation of the limit slider, the mold cleaning tank 1, and the guide groove on the inner wall of the extended unloading platform 7, the moving block 19 on the lead screw 17 smoothly drives the placement moving frame 8 to move towards the extended unloading platform 7 until the placement moving frame 8 and the mold on the pneumatic lifting platform 9 are precisely docked, ready to be transferred to the cleaning position.

[0048] During cleaning, the electric three-way valve 5 switches to the channel connected to the high-pressure water pump 16. The high-pressure water pump 16 draws water from the external water tank and pressurizes it. The high-pressure water flows into the multi-channel fitting 6 through the pipe. The multi-channel fitting 6 evenly distributes the high-pressure water to the end face cleaning square tube 2, the side cleaning square tube 3, and the bottom cleaning square tube 4. In the end face cleaning square tube 2, the high-pressure cleaning heads 10, which are evenly arranged at an angle, spray high-pressure water at a specific angle onto the mold end face, impacting the mold end face from multiple angles and effectively removing stubborn dirt. The side cleaning square tube 3 has two vertically arranged side high-pressure cleaning spray holes 11 evenly distributed on its inner side, which simultaneously spray high-pressure water onto both sides of the mold, achieving synchronous cleaning of both sides of the mold.

[0049] Specifically, at the four cleaning square tubes on the bottom surface, the cleaning spray holes 13 on the end face of the horizontal water pipes 12 spray high-pressure water upwards to clean the bottom surface of the mold. The support blocks 14 between the horizontal water pipes 12 ensure that the pneumatic lifting platform 9 remains suspended when it enters the bottom of the mold cleaning tank 1, ensuring thorough cleaning of the mold bottom surface. At this time, the ultrasonic transducer 22, installed at the bottom of the support block 14 corresponding to the position inside the mold cleaning tank 1, begins to operate. When an external high-frequency AC signal is applied to the piezoelectric ceramic element inside the ultrasonic transducer 22, based on the piezoelectric effect, the piezoelectric ceramic undergoes mechanical deformation at the same frequency as the electrical signal, thereby generating ultrasonic waves with a frequency in the range of 20kHz-100kHz. The ultrasonic waves propagate in the cleaning water, forming alternating longitudinal waves of varying density, triggering a cavitation effect. Tens of thousands of tiny bubbles collapse under pressure in the high-pressure area and rapidly expand in the low-pressure area. The high pressure of thousands of atmospheres generated by the collapse of these bubbles, combined with the high-pressure water sprayed upwards from the bottom, powerfully impacts the bottom surface of the mold, thoroughly removing stubborn dirt, oil stains, and other impurities, greatly improving the cleaning effect of the mold bottom surface. Wastewater generated during the cleaning process is discharged through a drain pipe 21 installed at the bottom of one side of the mold cleaning tank 1.

[0050] After cleaning, the electric three-way valve 5 switches to the channel connected to the high-pressure air pump 15. The high-pressure gas generated by the high-pressure air pump 15 passes through the multi-channel pipe 6 and the cleaning square pipe to quickly dry the water stains remaining on the mold surface and prevent the mold from rusting.

[0051] After the mold completes the cleaning and drying process, the motor 18 reverses, driving the lead screw 17 to rotate in the opposite direction, causing the placement and moving frame 8 to move laterally from inside the mold cleaning tank 1 towards the extended unloading platform 7. When the placement and moving frame 8 returns to above the extended unloading platform 7, the lifting cylinder 20 activates, pulling the pneumatic lifting platform 9 downwards, causing the mold to descend from the placement and moving frame 8 onto the extended unloading platform 7. At this point, the operator can remove the cleaned mold from the extended unloading platform 7, completing the unloading process.

[0052] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
