Description

Technical Field

[0001] This application relates to the field of foaming mold technology, and more specifically, to a dual-cavity synchronous rapid box foaming mold. Background Technology

[0002] A foam mold is a specialized mold used to manufacture foamed box-shaped products. It typically consists of a moving mold and a fixed mold, which, after closing, form a cavity that conforms to the shape of the target box. During production, liquid foam material is injected into the cavity and undergoes a foaming reaction to form the desired shape. The mold must withstand the pressure generated by the expansion of the foam material.

[0003] Existing foaming molds for housings all adopt a one-mold-one-cavity structure, which has certain limitations when production capacity demand increases, thus affecting the improvement of factory capacity. In addition, existing foaming molds for housings generally use water cooling, which is prone to problems such as scale buildup, poor water flow, and even leakage, affecting the cooling effect and mold life. Furthermore, after foaming, the workpiece fills the mold, making it difficult for personnel to remove the workpiece, which can easily lead to damage during removal. Utility Model Content

[0018] The above technical solution can ensure airtightness.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] (1) This utility model greatly improves production efficiency through the setting of dual cavities. Compared with single-cavity molds, it can perform foaming operations of two boxes at the same time, and mold two products at one time, directly doubling the production efficiency and meeting the needs of large-scale production. Moreover, by having two mold cavities in the same mold body, sharing structures such as cooling unit and demolding unit, it reduces the equipment footprint and mold manufacturing cost, and realizes intensive production. At the same time, through the synchronous operation of dual cavities, it can ensure the consistency of product quality, which is convenient for quality control and subsequent assembly processes.

[0021] (2) This utility model can achieve continuous and efficient heat dissipation through the circulating air cooling method of the cooling unit. The cooling air continuously circulates in the air duct to remove the heat of the mold in time. Compared with the traditional cooling method, the cooling time is greatly shortened and the production efficiency is improved. In addition, the air is cooled by the air refrigeration machine, which increases the temperature difference between the air and the mold, enhances the heat exchange efficiency, makes the mold cool more uniform and faster, ensures the quality of foaming and molding, and reduces product defects caused by uneven cooling. At the same time, the airflow guidance and one-way valve prevent the airflow backflow, reduce the risk of failure, and extend the service life of the mold.

[0022] (3) This utility model can achieve simultaneous demolding of molds with two cavities through the demolding unit. Compared with demolding one by one, it greatly shortens the demolding time, improves production efficiency, meets the needs of large-scale production, and has strong repeatability, reducing the probability of failure during the demolding process. At the same time, the bottom plate is moved up by using the inclined guide and pushing force of the trapezoidal block, which effectively reduces the overall complexity of the mold and the manufacturing cost, ensures a smooth demolding process, avoids damage to the foamed products in the mold due to rough demolding, and improves the product qualification rate.

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] Reference Figures 1-5 A dual-cavity synchronous rapid box foaming mold includes a mold body 1, a mold cavity 2 inside the mold body 1, two mold cavities 2, a cover plate 3 on one side of the mold body 1, and a dual-cavity assembly inside the mold body 1.

[0031] The dual-cavity assembly includes a cooling unit and a demolding unit. The cooling unit includes a fan 8. An air duct 4 is provided inside the mold body 1. The fan 8 is used to circulate air to cool the inside of the air duct 4. The demolding unit includes a base plate 15. The number of base plates 15 is set to two. A cylinder 17 is provided on one side of the mold body 1. The cylinder 17 is used to drive the two base plates 15 to move upward and eject.

[0032] The dual-cavity design greatly improves production efficiency. Compared with single-cavity molds, it can perform foaming operations on two boxes simultaneously, molding two products at once, directly doubling production efficiency and meeting the needs of large-scale production. Furthermore, by having the two mold cavities 2 share cooling and demolding units within the same mold body 1, it reduces equipment footprint and mold manufacturing costs, achieving intensive production. At the same time, the synchronous operation of the dual cavities ensures consistent product quality and facilitates quality control and subsequent assembly processes.

[0033] Reference Figures 1-5 A blower 8 is located on one side of the mold body 1. A blower 8 is connected to an exhaust pipe 10 on one side and a connecting pipe 7 on the other side. The connecting pipe 7 is connected to the air duct 4. A second baffle 6 is provided on one side of the interior of the air duct 4, and a first baffle 5 is provided on one side of the interior of the air duct 4. A one-way valve 9 is connected to one side of the connecting pipe 7. A first air duct 11 is connected to one side of the second baffle 6 and is connected to the air duct 4. An air pump 12 is connected to one end of the first air duct 11. An air cooler 13 is provided on one side of the air pump 12 and is connected to the air cooler 13. A second air duct 14 is connected to one side of the air cooler 13 and is connected to the connecting pipe 7 on the other end.

[0034] The cooling unit enables circulating air cooling, rapidly cooling the mold. Specifically, the fan 8 draws air through the exhaust pipe 10, and then sends the air into the air duct 4 via the connecting pipe 7. Inside the air duct 4, the first baffle 5 and the second baffle 6 guide the airflow direction (e.g., ...). Figure 3 Due to the action of the first baffle 5 and the second baffle 6, the air will eventually blow towards the second baffle 6. In order to reduce the temperature of the air and increase the temperature difference between the air and the mold, the air will be drawn out by the air pump 12 through the first air duct 11 and sent to the air refrigeration unit 13 for cooling. The cooled air will return to the connecting pipe 7 through the second air duct 14. Since the one-way valve 9 on the connecting pipe 7 prevents the airflow from flowing back, the cooling air will continuously circulate in the air duct 4, carrying away the heat of the mold and achieving rapid cooling of the mold.

[0035] The circulating air cooling method of the cooling unit can achieve continuous and efficient heat dissipation. By utilizing the coordinated operation of the fan 8, air pump 12, etc., the cooling air continuously circulates in the air duct 4, which can remove the heat of the mold in time. Compared with the traditional cooling method, the cooling time is significantly shortened and the production efficiency is improved. In addition, the air refrigeration unit 13 cools the air, increases the temperature difference between the air and the mold, enhances the heat exchange efficiency, and makes the mold cool more evenly and quickly, ensuring the quality of foaming and molding, reducing product defects caused by uneven cooling. At the same time, the airflow guidance and one-way valve 9 prevent airflow backflow, reduce the risk of failure, and extend the service life of the mold.

[0036] Reference Figures 1-5 The bottom of the mold body 1 is provided with a hollow plate 16, and the bottom of the two mold cavities 2 is provided with a base plate 15. The bottom of each base plate 15 is provided with a second trapezoidal block 20. The cylinder 17 is fixedly installed on one side of the hollow plate 16. The output end of the cylinder 17 is fixedly connected to a connecting frame 18. Both ends of one side of the connecting frame 18 are fixedly connected to a first trapezoidal block 19. The structure of each first trapezoidal block 19 is adapted to the structure of the corresponding second trapezoidal block 20.

[0037] The demolding unit can demold the molds in the two mold cavities 2 simultaneously. Specifically, when demolding is required, the cylinder 17 fixedly installed on one side of the hollow plate 16 is activated, and its output end pushes the connecting frame 18 forward. The first trapezoidal block 19 fixedly connected to both ends of one side of the connecting frame 18 moves accordingly. Since the structure of each first trapezoidal block 19 is adapted to the structure of the corresponding second trapezoidal block 20, during the movement, the first trapezoidal block 19 will interact with the second trapezoidal block 20. With the guidance and thrust of the inclined surface of the trapezoidal block, the bottom plate 15 located at the bottom of the two mold cavities 2 will move upward, thereby realizing the simultaneous ejection and demolding of the molds in the two mold cavities 2.

[0038] The demolding unit enables simultaneous demolding of both mold cavities 2. Compared to demolding one by one, this greatly shortens the demolding time, improves production efficiency, meets the needs of large-scale production, and ensures stability and reliability by using cylinder 17 to drive the connecting frame 18. It also has strong repeatability and reduces the probability of failure during the demolding process. At the same time, the trapezoidal block inclined surface guide and thrust are used to move the base plate 15 upward, which effectively reduces the overall complexity of the mold and the manufacturing cost, ensures a smooth and stable demolding process, avoids damage to the foamed products inside the mold due to rough demolding, and improves the product qualification rate.

[0039] Reference Figure 1 A sealing ring is provided on one side of the cover plate 3.

[0040] The sealing ring effectively seals the mold cavity 2, preventing leakage of foaming material, ensuring stable pressure during the foaming process, and improving product molding quality.

[0041] Working principle: First, the fan 8 draws air through the exhaust pipe 10, and then sends the air into the duct 4 via the connecting pipe 7. Inside the duct 4, the first baffle 5 and the second baffle 6 guide the airflow direction (e.g., ...). Figure 3 Due to the action of the first baffle 5 and the second baffle 6, the wind will eventually blow towards the second baffle 6. In order to reduce the temperature of the wind and increase the temperature difference between the wind and the mold, the wind will be drawn out by the air pump 12 through the first air duct 11 and sent to the air refrigeration unit 13 for cooling. The cooled wind will return to the connecting pipe 7 through the second air duct 14. Since the one-way valve 9 on the connecting pipe 7 prevents the airflow from flowing back, the cooling wind will continuously circulate in the air duct 4, taking away the heat of the mold and achieving rapid cooling of the mold.

[0042] When demolding is required, the cylinder 17 fixedly installed on one side of the hollow plate 16 is activated, and its output end pushes the connecting frame 18 forward. The first trapezoidal block 19 fixedly connected to both ends of one side of the connecting frame 18 moves accordingly. Since the structure of each first trapezoidal block 19 is adapted to the structure of the corresponding second trapezoidal block 20, the first trapezoidal block 19 will interact with the second trapezoidal block 20 during the movement. With the guidance and thrust of the inclined surface of the trapezoidal block, the bottom plate 15 located at the bottom of the two mold cavities 2 will be driven to move upward, thereby realizing the simultaneous ejection and demolding of the molds in the two mold cavities 2.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
