Description
Technical Field
[0001] This utility model relates to the field of foam molding mold technology, and in particular to a foaming mold. Background Technology
[0002] Foaming molds are tools used to manufacture foamed plastic products. By injecting foaming material and controlling temperature and pressure, the material is shaped. They are used in packaging, automotive, and construction industries, and bring multiple advantages through material and structural innovation. They can optimize foaming uniformity and shorten molding cycle. The modular quick-change structure facilitates rapid switching between production of different specifications of products, improving flexibility. Foaming molds can significantly improve production efficiency while ensuring product precision and quality, and promote the development of related industries towards high efficiency and intelligence.
[0003] A search revealed Chinese patent publication number CN213166499U, which discloses a foaming mold comprising a concave mold and a convex mold. The concave mold and convex mold are arranged opposite each other, and both have steam chambers inside. A steam inlet connector for the concave mold and a steam inlet connector for the convex mold are respectively provided on the upper side of the concave mold and communicate with the steam chambers. A drainage connector for the concave mold and a drainage connector for the convex mold are respectively provided on the lower side of the concave mold and communicate with the steam chambers. A feeding gun is provided above the water spray connector for the concave mold, and the feeding gun vertically penetrates the concave mold and communicates with the mold cavity between the concave mold and the convex mold. Steam inlet mold cores are provided on the concave mold and the convex mold located on the left and right sides of the mold cavity. This foaming mold of the present invention has a simple structure, is easy to operate, and solves the problem of inconsistent foaming mold layout in the prior art. The dense perforations in foaming molds result in uneven and dull product surfaces, failing to meet the surface requirements of special products and affecting their aesthetic appeal. While uniform steam inlet, aesthetically pleasing products, and simple processing offer broad application prospects, in practical applications, foaming molds still suffer from limited gas venting efficiency. They cannot collect and expel all the large amounts of gas generated during the foaming process in a timely manner. Furthermore, existing equipment lacks a specific structure to address the water droplets formed after the gas cools, causing water droplets to remain in the mold cavity or venting channels. This leads to material adhesion, mold corrosion, increased maintenance costs, and difficulty in achieving uniform heat dissipation based on the complex contours of the product. Consequently, thick-walled areas cool slowly, resulting in shrinkage and deformation, extending the overall molding cycle, and hindering the improvement of production efficiency. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a foaming mold, which aims to improve the problems that foaming molds still have in practical applications, such as limited gas discharge efficiency, water droplets remaining in the mold cavity or exhaust channel, causing material adhesion and mold corrosion, and difficulty in achieving uniform heat dissipation according to the complex contour of the product, which prolongs the overall molding cycle and restricts production efficiency.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a foaming mold, comprising a mold box, wherein a cooling and exhaust mechanism is provided on the top of the mold box, the cooling and exhaust mechanism is used to exhaust gas and rapidly cool the mold, and a sealing and buffering mechanism is provided on all four sides of the outer side of the mold box, the sealing and buffering mechanism is used to buffer and seal during foaming, and rubber plates are fixedly connected to adjacent sides of multiple sealing and buffering mechanisms, a demolding mechanism is provided on the inner bottom of the mold box, and a monitoring mechanism is provided on the outer front right end of the mold box; The cooling and exhaust mechanism includes an air box, the bottom of which is located at the top of the mold box. A sealing plate is fixedly connected to the bottom of the air box. Multiple longitudinal exhaust holes are provided on the left and right sides of the bottom of the sealing plate. Air chambers are provided on the left and right sides inside the air box. Breathing nets are fixedly connected to the top of the multiple longitudinal exhaust holes. Multiple condenser pipes are fixedly connected to the middle of the inner side of the air box. A fan is fixedly connected to the top of the middle of the inner side of the air box. Two exhaust ports are provided on the front and rear sides of the air box. A transverse air inlet pipe is provided on the adjacent side of the longitudinal exhaust hole in the middle of the left side and the longitudinal exhaust hole in the middle of the right side. Drainage components are provided on the front left and right sides of the air box.
[0006] The above technical solution involves multiple longitudinal vent holes at the bottom of the sealing plate arranged in a linear array to quickly capture foaming gas from multiple points on the top of the mold box, avoiding local accumulation that could lead to bubbles or uneven pressure. The gas enters the left and right air chambers through the longitudinal vent holes and is then directionally discharged through the front and rear vents, improving venting efficiency. The breather mesh at the top of the longitudinal vent holes is made of breathable but waterproof material, allowing gas to pass through while preventing condensate backflow, ensuring smooth venting while preventing water droplets from flowing back into the mold and contaminating the product, thus reducing the defect rate. The condenser pipe in the middle of the inner side of the air box and the top fan form convection cooling. The condenser pipe increases the heat exchange area, and the fan forces air to flow through the pipe wall, accelerating the heat exchange speed, shortening the cooling time, and improving production efficiency. The transverse air inlet pipe guides the cooling gas back to the mold box, optimizing the temperature field distribution. The drainage components outside the air box collect and discharge condensate droplets in a timely manner, preventing water accumulation from corroding the mold or blocking the venting channel, effectively solving the problems of poor venting, slow cooling, and inconvenient drainage in traditional molds.
[0007] As a further description of the above technical solution: The sealing and buffering mechanism includes multiple mounting plates, with each adjacent side of the mounting plates fixedly connected to the outer perimeter of the mold box. A sleeve is fixedly connected to the top of the left mounting plate, and a telescopic rod is fixedly connected to the bottom inner side of the sleeve. A spring damper is fixedly connected to the output end of the telescopic rod, and a push column is fixedly connected to the top of the spring damper. A lever plate is fixedly connected to the top of the push column, and the right side of the lever plate is fixedly connected to the left side of the rubber plate. A sliding assembly is provided on the outside of the push column, and a support assembly is provided at the bottom of the mounting plate.
[0008] Through the above technical solution: multiple mounting plates are connected around the outside of the mold box to form the basic framework of the mechanism. Inside the sleeve at the top of the left mounting plate, the telescopic rod 1 and the spring damper form an elastic linkage. In the initial stage of the foaming reaction, the telescopic rod 1 extends, and in conjunction with the initial elasticity of the spring damper, pushes the push column upward. The force arm plate at the top of the push column transmits the thrust to the rubber plate, tightly pressing the mold interface to achieve precise initial sealing and prevent material leakage. As the reaction progresses, the internal pressure increases, and the rubber plate is compressed by the reaction force to the spring damper and the telescopic rod 1. Through elastic deformation, the pressure is absorbed and the rubber plate extends and retracts synchronously, achieving adaptive adjustment of the buffer force. This avoids rigid extrusion that could cause mold deformation. At the same time, the sealing strength is dynamically adjusted according to pressure changes to ensure that the mold maintains good sealing performance under different working conditions, reduce product defects, and extend the mold's service life, providing solid support for the stability and efficiency of foaming production.
[0009] As a further description of the above technical solution: The drainage assembly includes two drainage pipes, with adjacent sides of the two drainage pipes connected to the front left and right sides of the outside of the mold box, and sealing caps provided on the opposite sides of the two drainage pipes.
[0010] The above technical solution involves two drainage pipes of the drainage component symmetrically connected to the left and right front ends of the mold box to collect and discharge condensate in a timely manner, preventing water accumulation from affecting the mold performance. The sealing cover keeps the pipes sealed when not draining, preventing external impurities from entering.
[0011] As a further description of the above technical solution: The demolding mechanism includes multiple telescopic rods, the bottoms of which are fixedly connected to the bottom of the mold box, and the output ends of which are fixedly connected to a sealing push plate. The sealing push plate is equipped with a temperature control component.
[0012] Through the above technical solution: multiple telescopic rods of the demolding mechanism are evenly distributed at the bottom of the mold box. The sealing push plate at the output end rises synchronously during demolding, smoothly ejecting the product and ensuring that the demolding process is efficient and smooth. The constant temperature component inside the sealing push plate maintains a suitable temperature to prevent the product from deforming due to temperature changes.
[0013] As a further description of the above technical solution: The sliding assembly includes multiple sliders, with each adjacent side of the sliders fixedly connected to the outer periphery of the push post, and multiple slide rails provided on the inner side of the sleeve.
[0014] Through the above technical solution: multiple sliders of the sliding component are fixed around the outside of the push column and precisely cooperate with the slide rail on the inside of the sleeve, so that the push column remains stable during the lifting process, avoids deviation or jamming, and ensures the action accuracy and reliability of the sealing buffer mechanism.
[0015] As a further description of the above technical solution: The support assembly includes multiple trapezoidal support plates, the tops of which are respectively fixedly connected to the bottoms of multiple mounting plates, and rubber support rods are fixedly connected between adjacent trapezoidal support plates.
[0016] Through the above technical solution: the multiple trapezoidal support plates in the support assembly have a structure that is wider at the top and narrower at the bottom, and the top is closely connected to the bottom of the mounting plate, providing a solid foundation support for the mold box. The inclined surface disperses the force, enhancing the overall structural stability. The rubber support rods between adjacent trapezoidal support plates have both elasticity and buffering performance, absorbing the vibration of equipment operation, avoiding stress concentration caused by rigid connection, and extending the service life of the mold.
[0017] As a further description of the above technical solution: The monitoring mechanism includes a temperature monitor, the rear of which is fixedly connected to the outer front right end of the mold box. Multiple sensors are fixedly connected to the rear of the temperature monitor and extend through the outer front right end of the mold box.
[0018] The above technical solution involves installing a temperature monitor on the front right side of the mold box, using multiple sensors to penetrate deep into the mold and monitor the temperature changes of the foaming reaction in real time and accurately, providing data support for process control.
[0019] As a further description of the above technical solution: The constant temperature component includes multiple heating wires, the outer sides of which are fixedly connected to the inner side of the sealing push plate, and a sealing plate is fixedly connected to the front side of the sealing push plate.
[0020] Through the above technical solution: multiple heating wires in the constant temperature component are evenly distributed inside the sealing push plate. When the temperature is detected to be lower than the set threshold, the heating is started. In conjunction with the sealing plate, heat loss is reduced, ensuring that the temperature of the product is constant during the demolding process. This prevents shrinkage, deformation, and surface cracking caused by sudden temperature drops, and achieves precise control of the temperature of the foaming process throughout the entire process.
[0021] This utility model has the following beneficial effects: 1. In this utility model, the gas box is equipped with a longitudinal exhaust hole to efficiently collect the gas generated during the foaming process and discharge it through the gas chamber and exhaust port to avoid gas stagnation. The condenser pipe and fan work together to form a rapid cooling structure, which accelerates the cooling of the gas and shortens the molding cycle. Water droplets are discharged in time through the drainage component to prevent water droplet retention from causing mold corrosion or material adhesion. This effectively solves the problems of poor exhaust, slow cooling and inconvenient drainage of existing molds, and improves product quality and production efficiency.
[0022] 2. In this utility model, the telescopic rod 1 inside the sleeve forms an elastic linkage with the spring damper. In the early stage of the foaming reaction, the push column pushes the rubber plate to tightly press against the mold interface through the lever plate to achieve initial sealing. As the foaming reaction proceeds, the internal pressure increases, and the rubber plate is pushed to compress the spring damper and the telescopic rod 1. The buffering force is adjusted adaptively through elastic extension and contraction to avoid mold deformation or material leakage caused by rigid extrusion, effectively improving the mold sealing and reliability, and reducing product defects caused by pressure fluctuations.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

The bottom of the air box 301 is located at the top of the mold box 1. A sealing plate 302 is fixedly connected to the bottom of the air box 301. Multiple longitudinal exhaust holes 303 are provided on both the left and right sides of the bottom of the sealing plate 302. Air chambers 310 are provided on both the left and right sides inside the air box 301. The longitudinal exhaust holes 303 efficiently collect the gas generated during the foaming process and discharge it through the air chambers 310 and the exhaust port 307 to avoid gas stagnation. A breather net 304 is fixedly connected to the top of each of the multiple longitudinal exhaust holes 303. The breather net 304 is breathable but waterproof to prevent liquid from being generated after the gas cools down. The gas box 301 has multiple condenser pipes 305 fixedly connected to the inner middle part, and a fan 306 fixedly connected to the top of the inner middle part of the gas box 301. The condenser pipes 305 and the fan 306 cooperate to accelerate the cooling of the gas and shorten the molding cycle. The gas box 301 has two exhaust ports 307 on the front and rear sides. The longitudinal exhaust port 303 on the left middle and the longitudinal exhaust port 303 on the right middle are respectively provided with transverse air inlet pipes 308 to guide the generated cooling gas to the mold box 1. The gas box 301 has drainage components 309 on the front left and right sides, and water droplets can be discharged in time through the drainage components 309. Specifically, the multiple longitudinal vent holes 303 at the bottom of the sealing plate 302 are arranged in a linear array, which can quickly capture the gas generated during the foaming process from multiple points on the top of the mold box 1, avoiding the formation of bubbles or uneven pressure due to local gas accumulation. The gas quickly enters the left and right air chambers 310 through the longitudinal vent holes 303, forming a diversion channel, and then is discharged directionally through the front and rear vent ports 307, greatly improving the venting efficiency. The breathable mesh 304 at the top of the longitudinal vent holes 303 is made of a breathable but waterproof material, allowing the gas to pass smoothly while preventing the backflow of condensate. This ensures the unobstructed gas discharge channel and prevents water droplets from flowing back and contaminating the mold and products, reducing the defect rate. The condenser pipe 305 in the middle of the inner side of the air box 301 forms a convective cooling with the top fan 306. The densely arranged condenser pipe 305 increases the heat exchange area, and the fan 306 forces air to flow quickly through the pipe wall, accelerating the gas heat exchange speed, greatly shortening the cooling time, and significantly improving production efficiency. The horizontal air inlet pipe 308 is used to guide the cooling gas back to the mold box 1 to optimize the temperature field distribution. The drainage components 309 on the left and right front sides of the air box 301 can collect and discharge the water droplets generated by condensation in time, avoiding water accumulation that corrodes the mold or affects the smooth flow of the exhaust channel. This effectively solves the problems of poor exhaust, slow cooling, and inconvenient drainage in traditional molds, providing a reliable guarantee for high-quality and high-efficiency foaming production.
[0027] Reference Figure 1 , Figure 2 and Figure 5 The sealing and buffering mechanism 4 includes multiple mounting plates 401. The adjacent sides of the multiple mounting plates 401 are fixedly connected to the outer perimeter of the mold box 1. A sleeve 402 is fixedly connected to the top of the left mounting plate 401. A telescopic rod 403 is fixedly connected to the bottom of the inner side of the sleeve 402. A spring damper 404 is fixedly connected to the output end of the telescopic rod 403. A push column 405 is fixedly connected to the top of the spring damper 404. A lever plate 406 is fixedly connected to the top of the push column 405. The telescopic rod 403 inside the sleeve 402 and the spring damper 404 form an elastic linkage. In the early stage of the foaming reaction, the push column 405 pushes the rubber plate 2 to tightly press against the mold interface through the lever plate 406 to achieve initial sealing. The right side of the lever plate 406 is fixedly connected to the left side of the rubber plate 2 and can adaptively adjust the buffering force through elastic extension and contraction. A sliding component 407 is provided on the outside of the push column 405, and a support component 408 is provided at the bottom of the mounting plate 401. Specifically, multiple mounting plates 401 are securely connected to the outer perimeter of the mold box 1, forming the basic framework of the mechanism and ensuring the stability of the component installation. Inside the sleeve 402 at the top of the left mounting plate 401, the telescopic rod 403 and the spring damper 404 form an elastic linkage core. In the initial stage of the foaming reaction, the telescopic rod 403 extends, and in conjunction with the initial elasticity of the spring damper 404, pushes the push column 405 upward. The lever plate 406 at the top of the push column 405 transmits the thrust to the rubber plate 2, causing it to tightly press against the mold interface, achieving a precise initial seal and effectively preventing material leakage. As the foaming reaction progresses... As the internal pressure gradually increases, the rubber plate 2, under the reaction force, compresses the spring damper 404 and the telescopic rod 403. At this time, the spring damper 404 absorbs the pressure through elastic deformation, and the telescopic rod 403 extends and retracts synchronously. The two work together to achieve adaptive adjustment of the buffering force, which can not only avoid mold deformation caused by rigid extrusion, but also dynamically adjust the sealing strength according to pressure changes, ensuring that the mold always maintains good sealing performance under different working conditions, reducing product defects caused by pressure fluctuations, and extending the service life of the mold, providing solid support for the stability and efficiency of foaming production.

Multiple slide rails 4071 are provided on the inner side of the sleeve 402. Specifically, the two drain pipes 3091 of the drainage component 309 are symmetrically connected to the front left and right sides of the mold box 1 to collect and drain condensate in a timely manner, preventing water accumulation from affecting the mold performance. The sealing cover 3092 keeps the pipes sealed when not draining, preventing external impurities from entering. The multiple telescopic rods 501 of the demolding mechanism 5 are evenly distributed at the bottom of the inner side of the mold box 1. The sealing push plate 502 at the output end rises synchronously during demolding, smoothly ejecting the product and ensuring efficient and smooth demolding. The constant temperature component 503 inside the sealing push plate 502 maintains a suitable temperature to prevent the product from deforming due to temperature changes and improve the quality of the finished product. The multiple sliders 4072 of the sliding component 407 are fixed around the outside of the push column 405 and precisely cooperate with the slide rail 4071 inside the sleeve 402, so that the push column 405 remains stable during the lifting and lowering process, avoiding deviation or jamming, ensuring the action accuracy and reliability of the sealing buffer mechanism 4, effectively solving the problems of drainage, demolding and motion stability, and providing comprehensive protection for the efficient operation of the foaming mold.

A sealing plate 5032 is fixedly connected to the front side of the sealing push plate 502. Specifically, the multiple trapezoidal support plates 4081 in the support assembly 408 have a structure that is wider at the top and narrower at the bottom. The top is tightly connected to the bottom of the mounting plate 401, providing a solid foundation support for the mold box 1. The inclined surface design effectively disperses the force and enhances the overall structural stability. The rubber support rods 4082 between adjacent trapezoidal support plates 4081 have both elasticity and buffering performance, which can absorb the vibration during equipment operation and avoid stress concentration caused by rigid connection, thus extending the service life of the mold.

Multiple heating wires 5031 in the constant temperature component 503 are evenly distributed inside the sealing push plate 502. When the temperature is detected to be lower than the set threshold, the heating wires 5031 start heating, which, together with the sealing plate 5032, reduces heat loss and ensures that the product temperature remains constant during demolding. This prevents shrinkage deformation and surface cracking caused by sudden temperature drops, achieving precise control of the foaming process temperature throughout the entire process and improving product qualification rate and production stability.
[0030] Working principle: The cooling and exhaust mechanism 3 at the top of the mold box 1 is activated after foaming begins: the longitudinal exhaust hole 303 at the bottom of the sealing plate 302 quickly collects the gas generated in the mold box 1, which is then diverted through the air chamber 310 and discharged through the exhaust port 307. The breather net 304 prevents condensate from flowing back. The condenser pipe 305 and fan 306 in the air box 301 accelerate the cooling of the gas. The transverse air inlet pipe 308 guides the cooling gas back to assist in the heat dissipation of the mold box 1. The drain pipe 3091 and the sealing cover of the drainage assembly 309 are also included. 3092 promptly drains condensate and prevents external impurities from entering. The sealing and buffering mechanism 4 on the outside of the mold box 1 plays a role in the initial stage of foaming. Multiple mounting plates 401 are fixed around the mold box 1. The telescopic rod 403 inside the sleeve 402 at the top of the left mounting plate 401 is linked with the spring damper 404, pushing the push column 405 through the lever arm plate 406 to tightly press the rubber plate 2 against the mold interface, achieving initial sealing. As the foaming reaction proceeds, the internal pressure increases, and the rubber plate 2 is compressed by the spring damper 4. 04 and telescopic rod 403 adaptively adjust the buffer force to prevent the mold from deforming due to excessive pressure, while maintaining the sealing strength. The slider 4072 on the outside of the push column 405 cooperates with the slide rail 4071 on the inside of the sleeve 402 to ensure stable lifting. The trapezoidal support plate 4081 and rubber support rod 4082 of the support component 408 provide stable support for the mechanism and buffer vibration. During the foaming reaction, the temperature monitor 601 of the monitoring mechanism 6 monitors the internal temperature of the mold box 1 in real time through the sensor 602, providing data for process control. After foaming is completed, the telescopic rod 501 of the demolding mechanism 5 pushes the sealing push plate 502 to smoothly eject the product. During this process, the constant temperature component 503 in the sealing push plate 502 maintains a suitable temperature through the heating wire 5031 and the sealing plate 5032 to prevent the product from deforming due to temperature changes. The drainage component 309 continuously and timely discharges the water droplets generated during the cooling process, realizing the high efficiency, stability and high quality of foaming production, extending the service life of the mold and reducing the defect rate.
