Description

Technical Field

[0001] This utility model relates to the field of ventilation cover mold technology, and in particular to a ventilation cover mold with an anti-misalignment structure. Background Technology

[0002] Ventilation covers are components used in ventilation systems of buildings, equipment, or other structures. They are mainly used to regulate airflow and prevent debris from entering ventilation ducts or equipment. They are usually made of metal, plastic, or other durable materials and have good corrosion resistance and mechanical strength. However, traditional ventilation covers often have problems such as misalignment and displacement during production and installation. This not only affects the ventilation effect but may also lead to safety hazards and increased energy consumption. Therefore, a ventilation cover mold with an anti-misalignment structure is needed.

[0003] In existing production technologies, the mold design for ventilation covers often lacks effective positioning and fixing structures, which makes it easy for various parts of the mold to shift or misalign during the molding process. This not only reduces the production efficiency of ventilation covers but also affects the quality and consistency of the products. In addition, if the ventilation cover is not accurately positioned during installation, it may also cause problems such as poor sealing of the ventilation system and poor airflow, further affecting its performance. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a ventilation cover mold with an anti-misalignment structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A ventilation cover mold with an anti-misalignment structure includes an operating table. A lower mold base is fixed to the top of the operating table. A forming cavity is formed on the top of the lower mold base. A lower template is slidably connected to the inner wall of the forming cavity. A U-shaped baffle is fixed to the inner wall of the forming cavity and is located below the lower template. A reset mechanism for resetting the lower template is provided inside the forming cavity. An upper mold base is provided on the top of the lower mold base. A feed pipe is provided through one side of the top of the upper mold base. An upper template is fixed to the bottom of the upper mold base. A gantry frame is fixed on the top of the operating table. A first lifting mechanism for raising and lowering the upper mold base is provided on the top of the gantry frame. Both ends of the frame are equipped with a first limiting mechanism for restricting the upper mold base, and the top of the lower mold base is equipped with a second limiting mechanism for restricting the upper mold base. The bottom of the lower mold plate is equipped with a cooling mechanism for cooling the lower mold plate. During use, the design of the first and second limiting mechanisms ensures that the upper and lower mold plates remain aligned during injection molding, thereby improving the accuracy of injection molding, ensuring the precise size of the ventilation cover, and facilitating subsequent installation. When the mold is removed, the reset mechanism automatically pushes the lower mold plate back, making it easy to remove the molded ventilation cover, thus improving the practicality of the device.

[0007] Preferably, the lifting mechanism includes two hydraulic push rods, which are respectively fixed to both ends of the top of the gantry frame, and the output shafts of both hydraulic push rods are fixed to the top of the upper mold base. The first limiting mechanism includes a slider, which is fixed to one side wall of the upper mold base. A groove is formed on the inner side wall of one end of the gantry frame, and a sliding rod is fixed to the top of the inner side wall of the groove. The slider is sleeved on the side wall of the sliding rod. The second limiting mechanism includes four rectangular blocks, which are respectively fixed to the four corners of the top of the lower mold base. Rectangular holes are formed at the four corners of the bottom of the upper mold base, and the four rectangular holes are respectively adapted to the four rectangular blocks. Driving the two hydraulic push rods causes the upper mold base to descend simultaneously. At this point, the two sliders, constrained by the two sliding rods, move downwards along the inner walls of the two sliding grooves until the lower mold base and the upper mold base are in a tight fit. At this point, the four rectangular blocks are located inside the four rectangular holes, ensuring that the upper mold plate is always directly above the lower mold plate without any positional shift. This results in a more accurate dimension of the injection-molded ventilation cover, facilitating subsequent installation and improving the quality of the ventilation cover. At this point, under the pressure of the upper mold plate, the bottom of the lower mold plate and the top of the U-shaped baffle are in close contact, causing the four springs to be in a compressed state. During injection molding, molten plastic is injected into the molding cavity through the feed pipe, thus molding the ventilation cover.

[0008] Preferably, the cooling mechanism includes a connecting cover fixed to the center of the bottom of the lower template. The connecting cover has a mounting hole at its bottom, and a semiconductor cooling chip is fixed to the inner wall of the mounting hole. Multiple first fins are linearly fixed at equal intervals on the cold end of the semiconductor cooling chip, and all the first fins are fixed to the lower template. Multiple second fins are linearly fixed at equal intervals on the hot end of the semiconductor cooling chip. The reset mechanism includes four springs, all of which are disposed inside the molding cavity. One end of each spring is fixed to one of the four corners of the bottom of the lower template, and the other end of each spring is fixed to the lower mold base. When the cooling element is energized, its cold end temperature drops rapidly, which in turn causes the surface temperature of the multiple first fins to drop rapidly, cooling the lower mold plate. This allows the ventilation cover to be formed faster, reducing the forming time and improving work efficiency. After forming, two hydraulic push rods are driven to move the upper mold base upward until the upper and lower mold bases separate. During the separation process, the upper and lower mold plates separate from each other. At this time, under the reaction force of four compressed springs, the lower mold plate is pushed upward, which pushes the formed ventilation cover plate out of the forming cavity for easy removal, improving the practicality of the device.

[0009] Preferably, the two outer side walls of the lower mold base are provided with heat dissipation windows, and both heat dissipation windows are connected to the molding cavity. The heat dissipation windows can dissipate heat from the hot end of the semiconductor cooling chip and discharge it to the outside of the lower mold base.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. During use, the design of the first and second limiting mechanisms of this device ensures that the upper and lower mold plates remain aligned during the injection molding process, thereby improving the accuracy of injection molding, ensuring the precise dimensions of the ventilation cover, and facilitating subsequent installation.

[0012] 2. During mold release, the reset mechanism automatically pushes the lower mold plate back, facilitating the removal of the formed ventilation cover and improving the practicality of the device.

[0013] 3. The cooling mechanism can quickly reduce the temperature of the lower mold plate, thereby shortening the molding time, improving work efficiency, and ensuring that the ventilation cover can be molded faster. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1 - Figure 5A ventilation cover mold with an anti-misalignment structure includes an operating table 1, a lower mold base 2 fixed to the top of the operating table 1, a molding cavity 13 opened on the top of the lower mold base 2, a lower template 14 slidably connected to the inner wall of the molding cavity 13, a U-shaped baffle 15 fixed to the inner wall of the molding cavity 13 and located below the lower template 14, the U-shaped baffle 15 is used to limit the movement range of the lower template 14 to ensure good contact between the lower template 14 and the upper template 7 during injection molding, a reset mechanism for resetting the lower template 14 is provided inside the molding cavity 13, an upper mold base 5 is provided on the top of the lower mold base 2, a feed pipe 21 is provided through one side of the top of the upper mold base 5, an upper template 7 is fixed to the bottom of the upper mold base 5, a gantry frame 4 is fixed on the top of the operating table 1, and a first lifting mechanism for lifting the upper mold base 5 is provided on the top of the gantry frame 4. The gantry frame 4 provides an overall support structure, bearing the upper mold base 5 and the lifting mechanism, ensuring stability and safety during mold operation. The inner walls at both ends of the gantry frame 4 are equipped with first limiting mechanisms to restrict the upper mold base 5, and the top of the lower mold base 2 is equipped with a second limiting mechanism to restrict the upper mold base 5. The bottom of the lower mold plate 14 is equipped with a cooling mechanism for cooling the lower mold plate 14. During use, the design of the first and second limiting mechanisms ensures that the upper mold plate 7 and the lower mold plate 14 remain aligned during injection molding, thereby improving the accuracy of injection molding and ensuring the precise dimensions of the ventilation cover, facilitating subsequent installation. When the mold is removed, the reset mechanism automatically pushes the lower mold plate 14 back, making it easy to remove the molded ventilation cover, thus improving the practicality of the device.

[0022] In this utility model, the lifting mechanism includes two hydraulic push rods 6, which are respectively fixed to the top ends of the gantry frame 4. The hydraulic push rods 6 serve as the main driving force of the lifting mechanism, providing powerful force through the hydraulic system to drive the upper mold base 5 to lift and lower, thereby achieving the closing and opening of the mold. The output shafts of both hydraulic push rods 6 are fixed to the top of the upper mold base 5. The first limiting mechanism includes a slider 11, which is fixed to one side wall of the upper mold base 5. A groove 9 is provided on the inner side wall of one end of the gantry frame 4. The top of the inner side wall of the groove 9... A sliding rod 10 is fixed, and a slider 11 is sleeved on the side wall of the sliding rod 10. The cooperation of the slider 11, the sliding rod 10, and the sliding groove 9 constitutes the first limiting mechanism, ensuring that the upper mold base 5 always moves along the prescribed track during descent, preventing positional displacement when the mold closes, thereby improving the accuracy of the injection molded product. The second limiting mechanism includes four rectangular blocks 12, which are respectively fixed at the four corners of the top of the lower mold base 2. Rectangular holes 8 are opened at the four corners of the bottom of the upper mold base 5, and the four rectangular holes 8 are respectively connected to the four rectangular blocks 12. The rectangular hole 8 and the rectangular block 12 form a second limiting mechanism to ensure that the relative position between the upper mold base 5 and the lower mold base 2 is stable when the upper mold base 5 is closed. The cooperation between the rectangular block 12 and the rectangular hole 8 ensures the alignment between the upper and lower molds and avoids misalignment. The two hydraulic push rods 6 drive the upper mold base 5 to descend simultaneously. At this time, the two sliders 11 move downward along the inner sidewalls of the two slides 9 under the restriction of the two slide rods 10 until the lower mold base 2 and the upper mold base 5 are in a tight fit. At this time, the four rectangular blocks 12 are located inside the four rectangular holes 8 respectively, so that the upper mold plate 7 is always directly above the lower mold plate 14 and there will be no positional deviation. This makes the dimensions of the injection molded ventilation cover more accurate, which provides convenience for subsequent installation and improves the quality of the ventilation cover. At this time, under the pressure of the upper mold plate 7, the bottom of the lower mold plate 14 and the top of the U-shaped baffle 15 are in close contact, so that the four springs 16 are in a compressed state. During injection molding, the molten plastic is injected into the molding cavity 13 through the feed pipe 21, and the ventilation cover is injection molded.

[0023] In this invention, the cooling mechanism includes a connecting cover 17, which is fixed to the middle of the bottom of the lower template 14. The connecting cover 17 has a mounting hole at its bottom, and a semiconductor cooling chip 18 is fixed to the inner wall of the mounting hole. Multiple first fins 19 are linearly fixed at equal intervals on the cold end of the semiconductor cooling chip 18, and all the first fins 19 are fixed to the lower template 14. Multiple second fins 20 are linearly fixed at equal intervals on the hot end of the semiconductor cooling chip 18. The reset mechanism includes four springs 16, all of which are located inside the molding cavity 13. The springs 16 act as a reset mechanism, providing a reaction force to ensure that the lower template 14 can quickly return to its original position after the mold is opened, facilitating the removal of the molded ventilation cover and increasing the practicality of the mold. One end of each of the four springs 16 is respectively connected to the lower template. The bottom four corners of the mold 14 are fixed, and the other ends of the four springs 16 are fixed to the lower mold base 2. After the semiconductor cooling chip 18 is energized, its cold end temperature drops rapidly, which in turn causes the surface temperature of the multiple first fins 19 to drop rapidly, thus cooling the lower mold plate 14. This allows the ventilation cover to be formed faster, reducing the molding time and improving work efficiency. After molding, the two hydraulic push rods 6 are driven to move the upper mold base 5 upward until the upper mold base 5 and the lower mold base 2 are separated. During the separation process, the upper mold plate 7 and the lower mold plate 14 separate from each other. At this time, under the reaction of the four compressed springs 16, the lower mold plate 14 is pushed upward, which pushes the formed ventilation cover out of the molding cavity 13 for easy removal, thus improving the practicality of the device.

[0024] In this invention, heat dissipation windows 3 are provided on both symmetrical outer side walls of the lower mold base 2, and both heat dissipation windows 3 are connected to the molding cavity 13. The heat dissipation windows 3 can dissipate heat from the hot end of the semiconductor cooling chip 18 to the outside of the lower mold base 2.

[0025] Working Principle: During operation, the device first drives two hydraulic push rods 6 to simultaneously lower the upper mold base 5. At this time, the two sliders 11, constrained by the two sliding rods 10, move downwards along the inner walls of the two sliding grooves 9 until the lower mold base 2 and the upper mold base 5 are in close contact. At this point, the four rectangular blocks 12 are located inside the four rectangular holes 8, ensuring that the upper mold plate 7 is always directly above the lower mold plate 14 without any positional shift. This results in a more accurate dimension of the injection-molded ventilation cover, facilitating subsequent installation and improving the quality of the ventilation cover. Meanwhile, under the pressure of the upper mold plate 7, the bottom of the lower mold plate 14 is in close contact with the top of the U-shaped baffle 15, compressing the four springs 16. During injection molding, molten plastic is injected into the molding cavity through the feed pipe 21. Inside the mold 13, the ventilation cover can be injection molded. During the molding process, the power switch of the semiconductor cooling chip 18 is turned on. After the semiconductor cooling chip 18 is powered on, its cold end temperature drops rapidly, which in turn causes the surface temperature of the multiple first fins 19 to drop rapidly, cooling the lower mold plate 14. This allows the ventilation cover to be molded faster, reducing the molding time and improving work efficiency. After molding, the two hydraulic push rods 6 are driven to move the upper mold base 5 upward until the upper mold base 5 and the lower mold base 2 separate. During the separation process, the upper mold plate 7 and the lower mold plate 14 separate from each other. At this time, under the reaction of the four compressed springs 16, the lower mold plate 14 is pushed upward, which pushes the molded ventilation cover out of the molding cavity 13 for easy removal, improving the practicality of the device.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
