Description

Technical Field

[0002] Rain boots are essential footwear for protecting feet during rainy weather and agricultural activities, making mold cooling crucial during their production. In the injection molding process of rain boots, due to potential material differences in different parts, layered injection molding is often necessary to prevent the mixing of injection molding compounds. This necessitates molds with excellent cooling capabilities to ensure production quality and efficiency.

[0003] Patent CN219522900U discloses a mold for producing rain boots with a cooling function. The mold is equipped with a circulating cooling mechanism, including a cooling device and a heat dissipation device. The coolant is circulated through a water pump, a delivery pipe, a water tank, and other structures. The circulating hot water is cooled by a heat dissipation box, a motor, a stirring blade, and a cooling fan.

[0004] However, the above solution still has the following shortcomings when implemented: Its heat dissipation device mainly relies on stirring and fan cooling, without introducing an active cooling mechanism. When the injection molding process generates high heat, the coolant cools down slowly and the heat dissipation efficiency is relatively limited. When facing high-intensity production demands, it cannot quickly reduce the coolant temperature to the ideal range, thus affecting the cooling effect of the mold and the production progress of the rain boots.

[0005] Therefore, we propose a mold for producing rain boots with a cooling function. Utility Model Content

The drive unit is located at the connection point of the heat-absorbing pipe and includes an inlet pipe located at the bottom connection point of the heat-absorbing pipe for coolant entry. The heat-absorbing pipe penetrates the back wall of the storage tank and connects to the interior of the inlet pipe, transporting coolant from the storage tank to the heat-absorbing pipe. The refrigeration device is located on the right side of the top of the heat-absorbing pipe for making ice blocks and throwing them into the storage tank.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Example

[0021] like Figures 1 to 4As shown, this utility model provides a technical solution: a mold for producing rain boots with a cooling function, characterized in that it includes a fixed base 10; a mold body 20, fixedly disposed on the top of the fixed base 10; a protective frame 60, which is disposed around the mold body 20 and fixedly disposed on the top of the fixed base 10, and has several openings on its four sides for heat dissipation; and two air-cooled heat dissipation structures 30, which are respectively disposed on the two side walls of the mold body 20 for auxiliary heat dissipation. The circulating water cooling structure 50 is located on the front of the fixed base 10 and is used for circulating water cooling of the mold body 20. It includes a heat absorption pipe 501, a storage tank 502, a stirring assembly, a drive unit, a monitoring and control assembly, and a refrigeration device. The heat absorption pipe 501 is arranged around the four walls of the mold body 20 and contains coolant. The drive unit is located at the connection of the heat absorption pipe 501 and passes through the back side wall of the storage tank 502 to connect with the inside of the liquid inlet pipe 503. It is used to transport the coolant inside the storage tank 502 to the heat absorption pipe 501. The refrigeration device is located on the right side of the top of the heat absorption pipe 501 and is used to make ice blocks and throw them into the storage tank 502. The stirring assembly is located at the center of the top of the heat absorption pipe 501 and is used to quickly mix and cool the ice blocks and coolant. The monitoring and control assembly is fixedly located at the heat absorption pipe 501 and is used to monitor the coolant temperature and turn the refrigeration device on or off according to the monitoring results.

[0022] When the mold body 20 generates heat during the injection molding process, the openings of the protective frame 60 first dissipate heat through natural convection. After the air-cooled heat dissipation structure 30 is activated, some of the heat on the surface of the mold body 20 is carried away by airflow. At the same time, the drive unit of the circulating water-cooled heat dissipation structure 50 pumps the coolant in the storage tank 502 into the heat absorption pipe 501. After absorbing the heat from the mold body 20, the coolant returns to the storage tank 502. When the monitoring and control component detects that the coolant temperature exceeds the threshold, the refrigeration equipment starts making ice and puts it into the storage tank 502. The stirring component accelerates the mixing of ice and coolant to form a low-temperature circulating medium, achieving efficient cooling.

[0023] The air-cooled heat dissipation structure 30 includes: Several heat dissipation fins 301 are equidistantly distributed on the side wall of the mold body 20 to guide the heat of the mold body 20. Two mounting bases 302 are respectively fixedly installed on the front and back sidewalls of several heat dissipation fins 301; Several cooling fans 303 are installed on two mounting bases 302 respectively, and are used to dissipate heat from several heat dissipation fins 301.

[0024] The heat dissipation fins 301 increase the heat dissipation area of ​​the mold body 20, and quickly conduct heat to the surface; after the cooling fan 303 is powered on, it generates forced airflow, which accelerates the flow of air between the heat dissipation fins 301, thereby carrying away the heat and achieving auxiliary heat dissipation for the mold body 20.

[0025] The drive unit includes: The liquid inlet pipe 503 is located at the bottom connection of the heat absorption pipe 501 and is used for the entry of coolant. The liquid outlet pipe 506 is located at the top connection of the heat absorption pipe 501 and is used to send the heat-absorbing coolant back to the interior of the storage tank 502. The connecting component 504 is connected to the liquid inlet pipe 503, and the two are connected. The first water pump 505 is fixedly installed on the front of the connecting member 504 and located inside the storage tank 502, and is used to send the coolant inside the storage tank 502 into the inlet pipe 503.

[0026] After the first water pump 505 starts, a negative pressure is formed at the connecting part 504, which draws the coolant in the storage tank 502 into the heat absorption pipe 501 through the liquid inlet pipe 503. After the coolant absorbs the heat of the mold body 20 in the heat absorption pipe 501, the temperature rises and flows back to the storage tank 502 through the liquid outlet pipe 506, completing one cycle.

[0027] Refrigeration equipment includes: An ice maker 513 is fixedly installed on the right side of the top of the heat absorption tube 501, and its bottom has an opening that allows ice to enter the storage box 502. The connecting pipe 512 is installed on the ice maker 513, and its other end passes through the side wall of the storage box 502 and is connected to the interior. The second water pump 511 is located at the connection of the connecting pipe 512 and is used to transport coolant to the ice maker 513 for ice making.

[0028] When the monitoring and control component detects that the coolant temperature exceeds the set value, the second water pump 511 starts and transports part of the coolant in the storage tank 502 to the ice maker 513 through the connecting pipe 512. After the ice maker 513 turns the coolant into ice cubes, it is released into the storage tank 502 through the bottom opening to reduce the overall temperature of the coolant.

[0029] Ice maker 513 can use mature products with existing technology on the market, such as the Zhigao ZB-100 ice maker, with an ice production capacity of 100kg / 24h, an ice storage capacity of 40kg, a power supply of 220V / 50Hz, and a refrigerant of R134a. The ice production capacity of 100kg / 24h can meet the ice demand for mold cooling during the production of rain boots, continuously replenish ice to the storage box 502, and assist the circulating water cooling structure 50 in efficient heat dissipation. Its 220V power supply adaptability is also good, making it easy to connect to common industrial power lines.

[0030] The stirring assembly includes: The drive motor 508 is fixedly installed at the center of the top of the storage box 502; The stirring rod 509 is rotatably mounted at the output end of the drive motor 508 and is connected to the storage tank 502 via a bearing; Several stirring blades 510 are fixedly arranged at equal intervals on the stirring rod 509, and are used to rotate with the stirring rod 509 to stir the coolant and ice in the storage tank 502.

[0031] When the drive motor 508 is powered on, it drives the stirring rod 509 to rotate, and the stirring blade 510 rotates accordingly, which accelerates the melting speed of ice in the coolant and makes the low temperature area and high temperature area fully mixed, ensuring that the coolant temperature in the storage box 502 is uniform and improving the overall heat dissipation effect.

[0032] The monitoring and control components include: Temperature sensor 514 is installed on the inner wall inside the storage tank 502 to monitor the coolant temperature; The controller 507 is located on the front wall of the storage tank 502 and is used for electrical connection with the drive unit, stirring assembly and refrigeration equipment.

[0033] Temperature sensor 514 monitors the temperature of the coolant inside storage tank 502 in real time and transmits the data to controller 507. Controller 507 compares the measured temperature with a preset threshold. When the temperature exceeds the threshold, it sends a signal to start the refrigeration equipment and stirring components. When the temperature is below the threshold, it controls the corresponding equipment to stop operating, thereby achieving intelligent temperature control.

[0034] The controller can adopt mature products with existing technologies on the market, such as Omron CP1H-XA40DT-D, which has 40 input / output points, 24 input points / 16 output points, built-in analog input / output functions, supports multiple communication protocols, has an operating temperature of 0-55℃, an IP20 protection rating, and a large number of I / O points to meet the control needs of multiple components such as drive unit, stirring assembly, and refrigeration equipment. In addition, the built-in analog function makes it easy to connect to analog devices such as temperature sensors, and can accurately realize the logic control of temperature regulation.

[0035] The temperature sensor 514 can be a mature product with existing technology on the market, such as the Huakong Xingye HK-PT100-3-200-A three-wire resistance temperature sensor with a measurement range of -200-200℃, an accuracy of ±0.15℃, and an IP65 protection rating. The temperature sensor probe is small in size and easy to install in a suitable position on the inner wall of the enclosure. The high-precision measurement can provide real-time and accurate feedback of the coolant temperature, providing reliable data for the controller 507.

[0036] The coolant is water.

[0037] Workflow When the rain boots are injection molded in the mold body 20, multiple components work together to initiate the heat dissipation process: I. Initial heat dissipation and air cooling assistance Natural convection cooling: The openings around the protective frame 60 allow air to circulate, carrying away some of the heat from the surface of the mold body 20 through natural convection, thus completing the initial heat dissipation.

[0038] Enhanced air cooling: The heat dissipation fins 301 increase the heat dissipation area of ​​the mold and conduct heat to the surface; after the cooling fan 303 is started, it generates forced airflow, which accelerates the flow of air between the heat dissipation fins and further assists in cooling.

[0039] II. Operation of the Circulating Water Cooling System Coolant circulation path: After the water pump of the drive unit starts, the coolant in the storage tank 502 is pumped into the heat absorption pipe 501 surrounding the mold body 20 through the inlet pipe 503. After the coolant absorbs the heat of the mold, it rises in temperature and flows back to the storage tank 502 through the outlet pipe 506.

[0040] Temperature monitoring and cooling triggering: The temperature sensor monitors the coolant temperature inside the storage tank in real time. When the temperature exceeds the threshold, the controller sends a signal. Start the refrigeration equipment to turn some of the coolant into ice blocks and put them into storage tank 502; Simultaneously, the stirring assembly is activated, and the stirring rod 509 drives the stirring blade 510 to rotate, accelerating the mixing of ice and coolant to form a low-temperature circulating medium.

[0041] Low-temperature medium recirculation: The mixed low-temperature coolant is pumped back into the heat absorption pipe 501 by the water pump, absorbs heat from the mold and then flows back. Through the cycle of "heat absorption-cooling-mixing-heat absorption", the mold temperature is continuously reduced to ensure the stability of the injection molding process.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
