[0049] like Figures 1-5 The diagram illustrates a mold pretreatment device according to one embodiment of this disclosure, which solves the problems associated with manual mold cleaning and the application of release agent. By setting up a mold cleaning device 1, a closed cleaning space 101 is constructed using a cover 100. The inlet 1011 and outlet 1012 of this space facilitate mold entry and exit. A brush 200 is located within the cleaning space 101 between the inlet 1011 and outlet 1012, brushing the passing mold to remove surface residues. Simultaneously, a dust collector 300 is connected to the cleaning space 101 to promptly remove dust generated during the brushing process, preventing dust from re-adhering to the mold. This achieves efficient and standardized mold cleaning, providing a good foundation for subsequent application of release agent and improving product processing efficiency and quality.

[0050] The cover 100 is rectangular or a similar regular shape to facilitate manufacturing and installation. The size of the cleaning space 101 inside the cover 100 is designed according to the size of common molds to ensure that the mold can pass through smoothly and that there is sufficient operating space around it.

[0051] The brush body 200 consists of multiple brush units, which are rationally arranged according to the shape of the mold and the areas to be cleaned. For example, for a rectangular mold, brush units are set at the top, bottom, and both sides of the cleaning space 101 to ensure that all surfaces of the mold can be effectively cleaned. The brush units can be rotary brushes, driven by a motor mounted on the outside of the cover 100 and connected to the brush units via a drive shaft. The bristles of the rotary brushes are made of wear-resistant materials with good cleaning capabilities, such as nylon bristles, and the bristle length is determined according to the unevenness of the mold surface and the cleaning requirements.

[0052] To accommodate molds of different sizes and shapes, the position of the brush body 200 can be adjusted. For example, a slide rail and slider structure can be provided inside the cover 100, with the brush unit mounted on the slider. The slider can be moved on the slide rail by a manual or electric device to adjust the position of the brush unit.

[0053] A baghouse dust collector can be selected as the dust collector 300 because it has high dust removal efficiency and good dust collection effect. The baghouse dust collector is connected to the cleaning space 101 through a pipe, the diameter of which is determined according to the suction power of the dust collector and the size of the cleaning space 101. A sealing device is installed at the connection between the pipe and the cleaning space 101 to prevent dust leakage.

[0054] When the mold enters the cleaning space 101 and the brush body 200 starts cleaning, the dust collector 300 operates simultaneously. The dust brushed off by the brush body 200 flies within the cleaning space 101, and the dust collector 300 draws the dust into its internal bag filter system through suction generated by the pipes. The dust is trapped inside the filter bags, and the purified air is discharged through the exhaust port. Regular cleaning of the filter bags ensures the continuous and efficient operation of the dust collector 300.

[0055] Compared to manual cleaning, this equipment, through its automated brush body 200 and high-efficiency dust collector 300, can quickly and thoroughly clean dust and mud from the mold surface. This improved cleaning efficiency and significantly reduced residual impurities on the mold surface after cleaning enhances the uniformity of subsequent application of release agent, thereby improving the product's molding effect and reducing the product defect rate.

[0056] Operators only need to feed the mold into the inlet 1011 of the cover 100, and the equipment automatically completes the cleaning process, greatly reducing labor intensity. At the same time, the equipment operates according to the preset cleaning program, and the cleaning process is standardized and uniform, avoiding problems such as incomplete cleaning or over-cleaning that may occur with manual cleaning, thus improving the stability and consistency of product processing.

[0057] In some examples, such as Figures 4-5 As shown, the brush body 200 can be a first brush roller 400 and a second brush roller 500, which can improve the mold cleaning effect. The two brush rollers are positioned within the cleaning space 101 with a gap for the mold to pass through. When the mold passes between them, the first brush roller 400 and the second brush roller 500 operate synchronously, brushing the mold surface from different angles. This design can cover a larger surface area of ​​the mold, enhancing the cleaning power of impurities on the mold surface. Compared to a single brush body structure, it can more comprehensively and deeply remove residual impurities such as dust and mud from the mold surface, providing a cleaner mold surface for subsequent application of release agent, thereby further improving the molding quality of the product.

[0058] The first brush roller 400 and the second brush roller 500 are arranged parallel to each other within the cleaning space 101. The distance between them is adjusted according to the thickness of common molds to ensure that the mold can pass through smoothly. At the same time, the brush rollers maintain appropriate contact pressure with the mold surface to achieve effective cleaning. The length of the brush rollers is determined according to the width of the mold, and is generally slightly longer than the width of the mold to ensure that the entire width of the mold can be cleaned.

[0059] The first brush roller 400 and the second brush roller 500 are mounted on the inner walls of the cover 100 on both sides via bearing seats. The bearing seats are made of high-strength metal material to ensure smooth and secure rotation of the brush rollers. The central axis of the brush rollers is perpendicular to the inner wall of the cover 100. With this mounting method, the brush rollers can stably brush the passing molds under the drive of the motor.

[0060] The brush roller body is made of metal, such as stainless steel, to ensure its strength and wear resistance. The brush roller surface is evenly covered with bristles made of wear-resistant and highly elastic materials, such as nylon or steel wire bristles. The appropriate bristle material is selected based on the surface material and impurities of the mold. For molds with softer surfaces, nylon bristles can be used to prevent scratching; for molds with stubborn impurities, steel wire bristles can be used.

[0061] Each brush roller is equipped with an independent drive motor. In one specific embodiment of this application, the drive motor is a three-phase asynchronous motor. Of course, users may use other motors as needed, and this is not limited here. The drive motor is installed on the outside of the cover 100 and is connected to the central shaft of the brush roller through a coupling. The motor is of the adjustable speed type so that the speed of the brush roller can be adjusted according to the cleanliness of the mold surface and the characteristics of the impurities. For example, for molds with more and more stubborn surface impurities, the speed of the brush roller can be appropriately increased to enhance the cleaning effect; for molds with more sensitive surfaces, the speed can be reduced to avoid damage to the mold.

[0062] During the mold cleaning process, the first brush roller 400 and the second brush roller 500 operate synchronously under the control of the control system, but in opposite directions. This way, when the mold passes between the two brush rollers, it receives brushing forces from two opposite directions simultaneously, making it easier to remove impurities from the mold surface. For example, the first brush roller rotates clockwise, while the second brush roller rotates counterclockwise.

[0063] When the mold enters the cleaning space 101 and reaches between the first brush roller 400 and the second brush roller 500, the brush rollers begin to scrub the mold. As the mold passes through the brush rollers, the bristles make full contact with the mold surface, brushing up dust, mud, and other impurities. Simultaneously, the dust collector 300 continuously operates, promptly removing the brushed dust to prevent it from re-adhering to the mold. Once the mold has completely passed through both brush rollers, a thorough scrubbing process is completed.

[0064] The coordinated operation of the first brush roller 400 and the second brush roller 500 ensures a more comprehensive and thorough cleaning of the mold surface. Compared to using only a single brush, the removal rate of impurities from the mold surface is increased, effectively reducing product defects caused by residual impurities on the mold surface and improving the product yield. The dual brush roller setup increases the contact area with the mold surface per unit time and the brushing frequency, thus improving cleaning efficiency compared to a single brush.

[0065] In some examples, such as Figures 4-5 As shown, a baffle 600 is installed in the mold cleaning device 1 of the mold pretreatment equipment, and is arranged at the inlet 1011 and outlet 1012 of the cleaning space 101. This baffle adheres to the mold surface as the mold passes through the cleaning space 101, further optimizing the sealing of the cleaning space. By adhering to the mold surface and sealing the inlet 1011 and outlet 1012, dust can be effectively prevented from escaping from these two locations during mold cleaning, thus avoiding pollution of the working environment and improving the dust collection efficiency of the dust collector 300. Furthermore, the baffle 600 can also maintain stable air pressure within the cleaning space 101 to a certain extent, ensuring that the cleaning work is carried out in a relatively stable environment, improving the cleaning effect and the stability of equipment operation.

[0066] The shape of the stop 600 is adapted to the shapes of the inlet 1011 and outlet 1012, and is typically rectangular to accommodate common rectangular mold inlet and outlet channels. Its length and width are slightly larger than the dimensions of the inlet 1011 and outlet 1012 to ensure complete coverage of the inlet and outlet. The thickness of the stop 600 is determined based on its material and actual usage requirements to ensure sufficient strength and sealing.

[0067] During the mold cleaning process, the brush body 200, the first brush roller 400, and the second brush roller 500, among other cleaning components, brush up the dust on the mold surface. At this time, the baffle 600 seals the inlet 1011 and the outlet 1012, effectively preventing dust from escaping into the working environment from these two openings. For example, when the dust collector 300 has insufficient suction or a large amount of dust is present at any moment, the baffle 600 can prevent dust from spreading and keep the working area clean.

[0068] The sealing effect of the baffle 600 helps maintain stable air pressure within the cleaning space 101. When the dust collector 300 is operating, a certain negative pressure environment is formed within the cleaning space 101. The baffle 600 reduces the entry of outside air, allowing the dust collector 300 to more effectively remove dust and improve dust collection efficiency. Simultaneously, the stable air pressure environment also facilitates the cleaning of impurities from the mold surface by the brush body 200 and brush rollers, preventing air pressure fluctuations from affecting the cleaning effect.

[0069] In some examples, the baffle 600 is designed as a flexible baffle. Specifically, the flexible baffle can be a brush. Of course, in other embodiments, the flexible baffle can also be a rubber curtain, etc., which is not limited here. Figure 5In the specific embodiment shown, flexible baffles are provided on both the upper and lower sides of the inlet 1011 and the outlet 1012, aiming to further improve the sealing performance of the cleaning space 101 and its adaptability to molds of different sizes. The flexible baffles can better conform to the mold surface, effectively preventing dust from escaping even if the mold surface has a certain degree of unevenness. The two baffles at the top and bottom form a double-layer sealing structure, enhancing the ability to block dust. At the same time, this design can adapt to the entry and exit of molds of different thicknesses. While ensuring the sealing effect, there is no need to frequently adjust the position of the baffles or replace baffles of different specifications, improving the versatility and ease of operation of the equipment.

[0070] Two sets of mounting structures, one upper and one lower, are respectively installed on the inner wall of the cover 100 at the inlet 1011 and the outlet 1012. A certain distance is maintained between the upper and lower baffles, the size of which is designed according to the thickness range of common molds. This distance accommodates the passage of molds of different thicknesses while ensuring that the two baffles form an effective sealing space. When the mold enters or exits, it presses against the upper and lower baffles, causing them to make tight contact with the mold surface, thereby preventing dust from escaping.

[0071] As the mold approaches the inlet 1011, the upper flexible baffle first contacts the top of the mold. Due to the baffle's flexibility, it deforms and conforms to the contour of the mold top, while the lower flexible baffle also slightly deforms as the mold approaches. The mold continues to advance, passing through the gap between the two baffles. During this process, both baffles maintain good contact with the mold surface, effectively preventing dust from escaping from the inlet within the cleaning space 101.

[0072] During the mold cleaning process, cleaning components such as the first brush roller 400 and the second brush roller 500 brush up the dust on the mold surface. At this time, the sealing structure formed by the upper and lower flexible baffles prevents dust from leaking into the external environment from the inlet 1011 and the outlet 1012. At the same time, this sealing structure helps to maintain stable air pressure in the cleaning space 101 and improves the dust collection efficiency of the dust collector 300.

[0073] When the mold is cleaned and ready to leave outlet 1012, the mold comes into contact with the upper and lower flexible baffles at the outlet again. The baffles will also deform according to the shape of the mold and fit tightly to ensure that dust does not escape from the outlet during the mold's departure. After the mold has completely left, the baffles return to their original shape, continuing to maintain a seal on the outlet.

[0074] The double-layer sealing structure formed by the upper and lower flexible baffles significantly improves the sealing performance of the cleaning space 101. The flexible baffles can automatically adapt to the surfaces of molds of different sizes and shapes, and the layout of the upper and lower baffles can accommodate the entry and exit of molds of different thicknesses without requiring complex adjustments or replacements. This makes the equipment more convenient for handling molds of various specifications.

[0075] In some examples, the stop 600 is designed as a rotating stop with two stops, one above the other, and springs are used to reset it to a vertical position. This optimizes the sealing performance and ease of operation of the mold cleaning device 1 in the mold pretreatment equipment. The rotating stops can flexibly rotate during mold entry and exit, accommodating molds of different shapes and sizes and reducing collisions and friction between the mold and the stops. The springs reset the stops to a vertical position, ensuring that they quickly return to a sealed position after the mold passes, effectively preventing dust from escaping from the cleaning space 101. Simultaneously, this design maintains stable air pressure within the cleaning space 101, improving the dust collection efficiency of the dust collector 300 and thus enhancing the mold cleaning effect.

[0076] When the mold moves in and out, it pushes the stop to rotate around the axis. At this time, the torsion spring twists and stores elastic potential energy. After the mold passes through, the torsion spring releases the elastic potential energy, causing the stop to rotate in the opposite direction and return to its vertical position, sealing the inlet 1011 or outlet 1012. During the resetting process, the elastic force of the torsion spring ensures that the stop can fit tightly against the edge of the inlet or outlet, effectively preventing dust from escaping.

[0077] During the mold cleaning process, the up-and-down rotating stop remains vertical under the action of the torsion spring, forming an effective sealing structure to prevent dust in the cleaning space 101 from leaking into the external environment. The stable sealed environment helps maintain stable air pressure in the cleaning space 101, improves the dust collection efficiency of the dust collector 300, and enables cleaning components such as the first brush roller 400 and the second brush roller 500 to more effectively clean impurities on the mold surface.

[0078] When the mold is cleaned and ready to leave outlet 1012, the mold pushes the upper and lower rotating stop at the outlet to rotate around the rotating shaft. After the mold has completely left, the upper and lower rotating stop quickly returns to the vertical position under the action of the torsion spring, restoring the seal on the outlet.

[0079] The rotating stop can flexibly adapt to the entry and exit of molds of different shapes and sizes, and quickly resets and seals after the mold passes through, effectively preventing dust from escaping. Compared with traditional fixed stops, dust leakage is reduced, significantly improving the sealing performance of the cleaning space 101 and improving the working environment.

[0080] The rotating stop design reduces collisions and friction between the mold and the stop, lowering equipment wear and the risk of failure. Simultaneously, the spring return mechanism ensures reliable stop reset, improving equipment stability and ease of operation. In actual production, this extends equipment maintenance cycles and increases production efficiency.

[0081] In some examples, such as Figures 1-3 , Figures 6-7As shown, the mold pretreatment equipment is equipped with a spraying device 2, which enables automated spraying of release agent after mold cleaning, solving the problems of high labor intensity and poor standardization associated with manual application of release agent. The cleaned mold is conveyed to the spraying position via a conveyor belt 700. A support frame 800 supports the spray nozzles 900 and positions them at a suitable angle and height. Several spray nozzles 900 can be distributed along the width of the mold, and the spraying area formed by all the spray nozzles 900 can cover the mold in the width direction. The liquid release agent is sprayed through atomizing nozzles and can be evenly distributed on the mold surface, providing good conditions for subsequent sheet molding and demolding, improving product processing efficiency and molding effect. In other embodiments, the spray nozzles 900 can also be distributed in other ways; for example, the distribution direction of the spray nozzles 900 can be at a certain angle to the width direction of the mold, which is not limited here.

[0082] The support frame 800 is an inclined frame structure. Specifically, the support frame 800 may include legs and a mounting beam. The mounting beam is located above the conveyor belt 700. One end of each leg is fixed to the ground or the equipment's support platform, and the other end is connected to the mounting beam to support it. The legs can be tilted, with the tilt angle designed according to the spraying angle of the nozzle 900 and the height of the mold, so that the release agent sprayed from the nozzle can cover the mold surface at a suitable angle. The legs are fixed to the ground or support platform by bolts or welding to ensure that there is no shaking during operation.

[0083] To accommodate molds of varying heights, the support frame 800 can be designed with an adjustable height. For example, retractable legs with graduated markings can be installed at the bottom of the support frame, allowing operators to adjust the leg height by loosening or tightening bolts, thereby changing the height of the top nozzle 900. Alternatively, an electric lifting mechanism can be used, allowing for precise height adjustment of the support frame via buttons on a control panel or an automated control system, improving operational convenience and accuracy.

[0084] Several nozzles 900 are arranged sequentially along the length of the support frame 800. The distance between adjacent nozzles is reasonably set according to the spray coverage of the nozzle and the width of the mold to ensure that the mold surface is fully covered by the release agent. The nozzles are selected for their good atomization effect and uniform spray, such as pressure atomizing nozzles or centrifugal atomizing nozzles. Pressure atomizing nozzles create atomization through the jetting of high-pressure liquid, while centrifugal atomizing nozzles utilize the centrifugal force generated by high-speed rotation to atomize the liquid. The appropriate nozzle type can be selected based on the characteristics of the release agent and the spraying requirements.

[0085] Each nozzle 900 is connected to a release agent storage tank via a pipe, and a solenoid valve is installed on the pipe to control the opening and closing of the nozzle. The control system allows for individual or group control of the nozzles, flexibly adjusting their operating status according to the shape of the mold and the areas requiring focused spraying. For example, the spray volume or spray time can be increased for the edges and corners of the mold. Simultaneously, a flow regulating valve is installed on the pipe to precisely control the release agent flow rate from each nozzle, ensuring uniform distribution of the release agent on the mold surface.

[0086] After being cleaned by the mold cleaning device 1, the mold is placed on the conveyor belt 700 by manual or automated means. The conveyor belt transports the mold to the spraying position below the support 800 at a set speed.

[0087] As the mold approaches the spraying position, sensors installed beside the conveyor belt, such as photoelectric sensors, detect its arrival and transmit signals to the control system. The control system then adjusts the conveyor belt speed, the number of nozzles 90° open, the spraying time, and the opening degree of the flow control valve based on the mold's size and preset spraying parameters.

[0088] When the mold reaches the spraying position, the control system activates the corresponding nozzle 900. Liquid release agent is delivered from the storage tank to the nozzle through pipeline, and after atomization, it is evenly sprayed onto the mold surface. As the mold moves with the conveyor belt, the nozzle continues to spray, completing the comprehensive coating of the mold surface.

[0089] After the mold leaves the spraying position, the control system shuts off the nozzle 900 and adjusts the conveyor belt speed according to the actual situation, preparing to receive the next mold for spraying.

[0090] Automated spraying methods are more efficient than manual application of release agent. The rational layout and precise control of the spray nozzles ensure that the release agent can be evenly covered on the mold surface, avoiding the uneven thickness problems that may occur with manual application. This increases the success rate of product demolding, significantly improves the molding effect, and reduces the defect rate.

[0091] Operators simply place the cleaned mold on the conveyor belt, and the equipment automatically completes the mold release agent spraying process, greatly reducing labor intensity. At the same time, the automated spraying process follows preset programs and parameters, ensuring standardized operation and improving the consistency and stability of product processing.

[0092] In some examples, such as Figures 6-7As shown, a storage tank 1000 and a pressure pump 1100 are added to the spraying device 2 of the mold pretreatment equipment to further optimize the spraying effect of the release agent. The storage tank 1000 is used to store the release agent, providing a stable supply of raw materials for the entire spraying process. The pressure pump 1100 is connected to the storage tank 1000 and the nozzle 900. By applying pressure to the release agent in the storage tank, it ensures that the release agent can be delivered to the nozzle 900 at a suitable pressure and flow rate, thereby ensuring that the release agent can be evenly and effectively covered on the mold surface after being atomized by the nozzle, improving the quality of mold pretreatment and providing better conditions for subsequent sheet molding and demolding.

[0093] The storage tank 1000 is typically cylindrical or square in shape, with a large volume to meet the demand for mold release agent within a certain timeframe. The volume is determined based on the equipment's usage frequency and mold processing capacity. The storage tank has an inlet and an outlet. The inlet is located at the top of the tank for easy addition of mold release agent; the outlet is located at the bottom of the tank and is connected to the inlet of the pressure pump 1100 via a pipe. To facilitate observation of the mold release agent level within the storage tank, a level gauge is installed. This level gauge can be a glass tube level gauge or an electronic level sensor, displaying the real-time level of the mold release agent in the storage tank.

[0094] Based on the characteristics of the release agent, the working pressure requirements of the nozzle 900, and the spraying flow rate requirements, a pressure pump 1100 with appropriate power and pressure range is selected. For example, a plunger pump or centrifugal pump capable of providing the corresponding pressure range can be used as the pressure pump. The pressure pump is installed near the storage tank 1000, with its inlet connected to the outlet of the storage tank via a pipe, and its outlet connected to the inlet of the nozzle 900 via a pipe. During installation, ensure the motor is securely mounted to avoid vibration affecting equipment performance during operation. Simultaneously, a flexible connection, such as a rubber hose, should be used at the connection between the motor and the pipe to reduce vibration transmission and facilitate pipe installation and maintenance.

[0095] The pressure pump 1100 is equipped with a pressure regulating valve and a flow controller, which control the pressure and flow rate of the release agent by adjusting the motor speed or valve opening. The pressure regulating valve is installed on the motor's outlet pipe and can manually or automatically adjust the output pressure of the release agent according to the working pressure requirements of the nozzle 900. The flow controller monitors the release agent flow rate in real time and feeds the signal back to the control system. The control system automatically adjusts the motor's operating parameters according to the preset flow rate value to ensure that the release agent is delivered to the nozzle at a stable flow rate. For example, when the flow rate is detected to be lower than the set value, the control system automatically increases the motor speed to increase the flow rate; conversely, when the flow rate is too high, the motor speed is reduced.

[0096] Liquid mold release agent is injected into storage tank 1000 through the inlet, and the level gauge displays the liquid level of the mold release agent in the storage tank in real time. When the mold reaches the spraying position, the sensor detects the mold signal and transmits it to the control system, which then starts the pressure pump 1100. The pressure pump applies pressure to the mold release agent in storage tank 1000, drawing it out from the outlet of the storage tank and delivering it through a pipeline to the spray head 900. During the delivery process, the pressure regulating valve and flow controller work together to ensure that the mold release agent is stably delivered to the spray head at the set pressure and flow rate.

[0097] After receiving release agent with appropriate pressure and flow rate, nozzle 900 atomizes the release agent and sprays it evenly onto the mold surface. As the mold moves on conveyor belt 700, the entire mold surface is coated. During the coating process, the control system continuously monitors the pressure and flow parameters of the pressurized pump and makes fine adjustments as needed to ensure the quality of the release agent coating.

[0098] The installation of storage tank 1000 and pressure pump 1100 ensures a stable supply and precise delivery of the release agent. Compared with traditional simple storage and gravity-flow supply methods, the supply stability of the release agent is improved, reducing the problem of uneven spraying caused by unstable supply and improving the consistency of the release agent coating on the mold surface.

[0099] By precisely controlling the pressure and flow rate of the release agent through the pressure pump 1100, the nozzle 900 can better atomize the release agent, improving the uniformity of its coverage on the mold surface. This further enhances the demolding effect, significantly improves the molding quality of the product, and also reduces the waste of release agent.

[0100] In some examples, such as Figures 1-3 , Figure 8 As shown, a drying device 3 is installed in the mold pretreatment equipment to solve the problem of the release agent being damp and affecting the demolding effect. The drying device 3 is located on one side of the spraying device 2. After the mold is sprayed with the release agent by the spraying device 2, it enters the drying space 301 of the drying device 3. Through the structure of a drying fan combined with a heating wire, the heating wire heats the air, and after the drying fan is started, the hot air is blown to the mold surface through the pipe, so that the release agent dries quickly. This design ensures that the release agent can be quickly dried on the mold surface, avoiding demolding difficulties caused by damp release agent, and improving the success rate and quality of sheet molding.

[0101] The drying space 301 of the drying device 3 is typically a rectangular channel. Its length, width, and height are designed according to the dimensions of common molds to ensure that the molds can pass through smoothly and that there is adequate space around them. The drying space has an inlet and an outlet at each end, which connect to the conveyor belt 700 of the spraying device 2 and the receiving device for subsequent processes to ensure that the molds can enter and exit smoothly.

[0102] The drying device 3 is located adjacent to the spraying device 2. The conveyor belt 700 of the spraying device 2 directly transports the mold after the release agent has been sprayed to the entrance of the drying space 301. This reduces the time the mold is exposed to air, lowers the possibility of the release agent becoming damp again, and improves the overall working efficiency of the equipment.

[0103] Heating wires are installed inside the air duct of the drying fan, arranged in a spiral or mesh pattern to increase the contact area with air and improve heating efficiency. The power of the heating wires is selected based on the size of the drying space 301, the material and number of molds, and the required drying speed. The heating temperature of the heating wires is controlled by a temperature controller to meet the drying requirements of different types of release agents.

[0104] Centrifugal or axial fans with sufficient air pressure and volume are selected as the drying fans. The air volume of the fan is determined based on the volume of the drying space 301 and the required air circulation speed. The air pressure must ensure that hot air can be effectively blown to all parts of the mold. The drying fans are installed on the top or side of the drying device 3 and connected to the drying space 301 through ventilation ducts.

[0105] The diameter of the ventilation duct is determined based on the air volume and velocity of the drying fan. The ventilation duct extends from the drying fan to both sides of the drying space 301, with downward air outlets evenly distributed on the duct.

[0106] The air outlet can be round, square, or rectangular, and its size is determined according to the size of the mold and the required hot air coverage area to ensure that the hot air can be blown evenly onto the mold surface, allowing the release agent to dry quickly and evenly. To adjust the blowing angle and direction of the hot air, the air outlet can be designed to be adjustable, allowing operators to adjust it according to the shape of the mold and the actual drying effect.

[0107] After the mold release agent is applied, the mold is conveyed by conveyor belt 700 to the entrance of the drying space 301. Before the mold enters the drying space, the temperature controller sets the heating temperature of the heating wire and the operating parameters of the drying fan according to the type of mold release agent and process requirements.

[0108] After the mold enters the drying chamber 301, the heating wires begin to heat the air in the air duct. Once the set temperature is reached, the drying fan starts, blowing hot air downwards from the air outlet onto the mold surface through the ventilation duct. The hot air evenly covers the mold, causing the moisture in the release agent to evaporate rapidly. During the drying process, a temperature sensor monitors the temperature in the drying chamber in real time and feeds the data back to the temperature controller. The temperature controller automatically adjusts the power of the heating wires based on the feedback data to maintain a stable temperature in the drying chamber. Simultaneously, the operator can observe the drying process of the mold through the observation window and fine-tune the angle of the air outlet and the operating parameters of the drying fan as needed.

[0109] After the mold has been dried in the drying chamber 301 for a certain period of time, the release agent is completely dry. The mold then exits from the outlet of the drying chamber and proceeds to the next process. The drying time depends on factors such as the size of the mold, the type of release agent, and the drying temperature.

[0110] Drying device 3 effectively solves the problem of damp release agent. After drying, the release agent is evenly dried on the mold surface, improving the demolding success rate. During the demolding process, surface defects caused by damp release agent are reduced, significantly improving product quality and lowering the defect rate.

[0111] The drying device 3 works in close coordination with the spraying device 2 to achieve continuous operation of mold pretreatment, reducing the waiting time for molds to dry. This improves the overall production efficiency of the equipment, enabling it to process more molds per unit time and meeting the needs of expanded production scale.

[0112] In some examples, such as Figures 1-3 , Figure 9 As shown, a shelf 1300, a transfer rack 1400, and a transfer robot 1500 are installed to optimize the storage and transfer process of molds, improving the automation level and production efficiency of the equipment. The shelf 1300 stores multiple molds, providing temporary storage space for easy management and scheduling. The transfer rack 1400 is positioned between the shelf 1300 and the mold cleaning device 1, serving as an intermediate transition platform for mold transfer. The transfer robot 1500 can precisely move molds from the shelf 1300 to the transfer rack 1400, automating the mold transfer process, reducing manual intervention, lowering labor intensity, and ensuring the efficient and orderly execution of the mold pre-processing procedure.

[0113] The 1300 shelving unit adopts a multi-layer frame structure, and the number of layers is determined according to the actual site height and mold storage requirements. The height of each layer is adjusted according to the height of the molds to ensure that the molds can be placed stably, and there is sufficient space between layers to facilitate the operation of the transfer robot.

[0114] The transfer frame 1400 is equipped with a positioning device adapted to the mold, such as a positioning pin or positioning groove, to ensure that the mold is accurately positioned on the transfer frame. Simultaneously, one side of the transfer frame is designed with a structure that connects to the inlet of the mold cleaning device 1. For example, a retractable guide rail is provided on the side of the transfer frame near the mold cleaning device 1. When the transfer frame moves to the vicinity of the inlet of the mold cleaning device 1, the guide rail extends and connects with the guide rail at the inlet of the mold cleaning device 1, facilitating the smooth entry of the mold into the mold cleaning device 1.

[0115] The actuators of the 1500 transfer robot are designed according to the shape and size of the mold, and commonly include gripper type, suction cup type, or magnetic type. For molds with flat surfaces, suction cup type or magnetic type end effectors can be used, and the suction force can be adjusted according to the weight of the mold; for irregularly shaped molds, gripper type end effectors are more suitable, and the shape of the gripper and the clamping force can be customized according to the shape of the mold.

[0116] The transfer robot is equipped with a control system that specifies which storage location on shelf 1300 to retrieve the mold from and place it at the exact position on transfer rack 1400. Based on the set task and information from sensors, the system controls the robot's movement trajectory, speed, and force. Sensors include position sensors and force sensors. Position sensors monitor the robot's position in real time to ensure accurate arrival at the target location; force sensors monitor the force between the end effector and the mold to prevent damage to the mold during gripping and handling.

[0117] The molds to be processed are placed in the corresponding storage positions on shelf 1300, and the storage location and related information of the molds are recorded by scanning equipment. When pre-processing of the molds is required, the operator inputs the transfer task command on the control system. Based on the command and the storage information of the molds on shelf 1300, the control system plans the movement path of the transfer robot 1500.

[0118] The transfer robot 1500 moves along a planned path to the designated storage location on the shelf 1300 and grasps the mold using its end effector. During the grasping process, force sensors monitor the grasping force in real time to ensure that the mold is grasped stably and without damage. Then, the robot moves the mold to the top of the transfer frame 1400 and accurately places it on the transfer frame according to the positioning device on the transfer frame.

[0119] After the mold is placed on the transfer frame 1400, the transfer frame moves to the vicinity of the mold cleaning device 1 via rollers, extends the docking guide rail to dock with the inlet of the mold cleaning device 1, and transports the mold to the mold cleaning device 1 for processing.

[0120] The coordinated operation of the 1300 shelving unit, 1400 transfer rack, and 1500 robotic transfer arm automates mold storage and transfer. Compared to manual mold handling, production efficiency is increased, waiting time and errors during manual handling are reduced, and the continuity and efficiency of the mold pre-processing flow are ensured. Operators only need to set transfer tasks on the control system; they do not need to directly handle the molds, significantly reducing labor intensity.

[0121] In some examples, such as Figure 9As shown, the transfer robot 1500, through the coordinated operation of the horizontal transfer frame 1501, the lifting component 1502, and the gripping component 1503, achieves efficient and precise transfer of molds from the shelf 1300 to the transfer rack 1400. The horizontal transfer frame 1501 is responsible for horizontal movement and positioning between the shelf 1300 and the transfer rack 1400, enabling the transfer robot 1500 to accurately reach the storage location of the mold and the placement position of the transfer rack. The lifting component 1502 moves up and down on the horizontal transfer frame 1501, adjusting the height of the gripping component 1503 to contact the mold and complete the suction operation. The gripping component 1503 utilizes its own suction function to firmly grasp the mold, ensuring the stability of the mold during the transfer process, avoiding mold damage that may occur due to manual transfer, and improving the automation level and operating efficiency of the entire mold pretreatment equipment.

[0122] The transverse frame 1501 spans between the rack 1300 and the transfer frame 1400, moving on a pre-set track via rollers or sliders at its bottom. The track is mounted on the ground or a dedicated support beam to ensure the straightness and stability of the transverse frame's movement. The drive system uses a servo motor, which is connected to a transmission screw via a reducer. The screw engages with a nut on the transverse frame. When the servo motor operates, it drives the screw to rotate, causing the nut to move along the screw, thus achieving linear movement of the transverse frame on the track.

[0123] The lifting component 1502 is mounted on the transverse frame 1501 and employs a scissor lift mechanism or an electric push rod lift mechanism. Taking the scissor lift mechanism as an example, it consists of multiple cross-hinged connecting rods, resembling scissors. The bottom connecting rod is fixed to the transverse frame 1501, and the top connecting rod is connected to the gripper 1503. When the drive device, such as a hydraulic cylinder or an electric push rod, acts on the scissor mechanism, the included angle between the connecting rods changes, thereby driving the gripper 1503 to achieve lifting motion. The lifting height of the lifting component 1502 is controlled by adjusting the working stroke of the drive device through the controller. During the lifting process, the displacement sensor monitors the lifting height in real time and feeds the signal back to the controller so that the working state of the drive device can be adjusted in a timely manner to ensure the accuracy of the lifting height. In addition, to prevent the lifting component from falling accidentally during operation, a fall arrestor, such as a mechanical fall arrestor or an electromagnetic fall arrestor, can be installed. Once an abnormal descent speed is detected, the brake is immediately triggered to ensure the safety of the equipment and the mold.

[0124] The gripper 1503 selects a suitable gripping method based on the material and surface characteristics of the mold. Common methods include vacuum adsorption, magnetic attraction, and mechanical gripping. For example, vacuum adsorption can be used to adsorb non-metallic sheets. The vacuum adsorption gripper has multiple vacuum suction cups at its bottom. A vacuum pump extracts air from the suction cups to create negative pressure, thereby adsorbing the mold. The layout of the suction cups is optimized according to the shape and size of the mold to ensure uniform distribution of adsorption force and prevent the mold from tilting or falling off during the adsorption process.

[0125] Upon receiving the transfer instruction, the control system drives the transverse frame 1501 to move along the track above the mold based on the mold's position information on the shelf 1300. Once in position, the lifting component 1502 descends, bringing the gripping component 1503 close to the mold surface.

[0126] Once the gripper 1503 reaches the appropriate position, the adsorption function is activated based on the mold material and the preset adsorption method. The vacuum adsorption gripper activates the vacuum pump to allow the suction cup to adsorb the mold. During the adsorption process, the adsorption force is monitored in real time to ensure the mold is firmly adsorbed.

[0127] After confirming that the mold is firmly attached, the lifting component 1502 rises and lifts the mold from the shelf 1300. Subsequently, the transverse frame 1501 moves above the transfer frame 1400.

[0128] After the transverse frame 1501 reaches above the transfer frame 1400, the lifting component 1502 descends again, accurately placing the mold on the transfer frame 1400. Then, the gripper 1503 releases its grip, the lifting component 1502 rises, and the transverse frame 1501 returns to its initial position, awaiting the next transfer task.

[0129] The drive system of the transverse frame 1501 and the height control of the lifting component 1502 significantly improve the positioning accuracy during mold transfer, effectively preventing mold collisions and damage caused by inaccurate positioning. Compared to manual transfer, the improved transfer accuracy significantly enhances the overall operational stability of the mold pretreatment equipment. The automated operation of the transfer robot 1500 greatly reduces manual intervention, shortens mold transfer time, and improves transfer efficiency. Compared to manual transfer, the increased transfer efficiency better meets the production needs of large-scale mold pretreatment while reducing the labor intensity of operators. The multiple adsorption methods of the gripper 1503 can adapt to molds of different materials and shapes, enhancing the versatility of the transfer robot for various molds.
