Description

Technical Field

[0001] This utility model relates to a sound-absorbing panel demolding device, specifically a sound-absorbing panel forming mold demolding device, belonging to the field of sound-absorbing panel technology. Background Technology

[0002] Acoustic panels are an ideal sound-absorbing decorative material. They have advantages such as sound absorption, environmental friendliness, flame retardancy, heat insulation, thermal insulation, moisture resistance, mildew resistance, easy dust removal, easy cutting, mosaic capability, simple construction, good stability, good impact resistance, good independence, and high cost performance.

[0003] Utility model patent CN213227642U discloses a molding die for a mineral sound-absorbing panel, including a molding machine body. This utility model solves the problem of existing mineral sound-absorbing panels requiring a molding machine to drive the die during processing, but lacking a positioning and guiding function for the upper die, often resulting in deviations and a high defect rate in the molded products due to prolonged use. This is achieved through the coordinated use of a sliding sleeve, sliding rod, upper die, lower die, oil storage cotton, oil outlet strip, and shock absorption mechanism.

[0004] During the production of sound-absorbing panels, materials need to be injected into the mold and then cooled and shaped. Although the mold in the aforementioned patent avoids mold misalignment, the sound-absorbing panel tends to stick to the mold after it is formed, making it difficult to demold the sound-absorbing panel. To address this issue, we provide a demolding device for sound-absorbing panel forming molds. Utility Model Content

[0005] The purpose of this utility model is to provide a demolding device for sound-absorbing panel forming molds in order to solve the above-mentioned problems, thereby addressing the difficulty in demolding sound-absorbing panels as described in the prior art.

[0006] This utility model is achieved through the following technical solution: a demolding device for a sound-absorbing panel forming mold.

[0007] The device includes a fixed base and a mold chamber. A side pressure plate is rotatably connected to the surface of the mold chamber. A support mechanism is provided inside the mold chamber. The support mechanism includes a connecting frame and an eccentric wheel. A support plate is fixedly connected to the top of the connecting frame, and a connecting ring is fixedly connected to the bottom of the connecting frame. The connecting ring is sleeved on the outside of the eccentric wheel. A positioning mechanism for positioning the connecting ring is provided on the surface of the fixed base. The positioning mechanism includes a support frame that is slidably connected to the connecting ring.

[0008] Preferably, a support frame is fixedly connected to the bottom of the mold compartment, and the bottom end of the support frame is fixedly connected to a fixed base. A hydraulic push rod is rotatably connected to the surface of the fixed base, and the output end of the hydraulic push rod is rotatably connected to a side pressure plate. The support frame supports and fixes the mold compartment, and the support frame facilitates the maintenance and repair of the equipment inside the mold compartment.

[0009] Preferably, the support plate is slidably connected to the mold chamber, and a movable frame is slidably connected inside the connecting ring. One end of the movable frame is fixedly connected to a connecting plate. The vibration is transmitted to the support plate by the rotating impact of the eccentric wheel on the movable frame, and then through the movable frame and the connecting ring, which facilitates the separation of the support plate from the sound-absorbing plate.

[0010] Preferably, a buffer spring is sleeved on the outside of the movable frame, and the two ends of the buffer spring are fixedly connected to the connecting ring and the connecting plate, respectively. The buffer spring can transmit and amplify the vibration received by the movable frame, thereby improving the stability of the movable frame driving the support plate to vibrate.

[0011] Preferably, the eccentric wheel is rotatably connected to the fixed base, and a speed reducer is fixedly connected to the surface of the fixed base. The output end of the speed reducer is fixedly connected to the eccentric wheel, and the speed reducer drives the eccentric wheel to rotate at a uniform and stable speed.

[0012] Preferably, a motor is fixedly connected to the surface of the fixed base, and the output end of the motor is fixedly connected to the input end of the reducer, so that the motor controls the rotation of the reducer.

[0013] Preferably, the bottom of the support frame is rotatably connected to a support roller, and the support roller is slidably connected to a fixed base. An electric push rod is fixedly connected to the surface of the fixed base, and the output end of the electric push rod is fixedly connected to the support frame. The friction between the support frame and the fixed base is reduced by the support roller.

[0014] This utility model provides a demolding device for sound-absorbing panel forming molds, which has the following beneficial effects:

[0015] 1. This sound-absorbing panel forming mold demolding device combines a side pressure plate and a mold chamber to form a mold, facilitating the production of sound-absorbing panels. The rotation of the eccentric wheel causes the connecting ring to vibrate up and down, which in turn causes the support plate to vibrate up and down, causing the support plate to separate from the formed sound-absorbing panel on the ground. This facilitates the demolding operation of the produced sound-absorbing panel and improves the convenience of demolding. The support frame supports and fixes the connecting ring, preventing it from sliding up and down during the production of the sound-absorbing panel and improving the stability of the support plate.

[0016] 2. The demolding device for the sound-absorbing panel forming mold supports and fixes the mold chamber through a support frame. The support frame also facilitates maintenance and repair of the internal equipment of the mold chamber, improving the ease of use of the device. Through the hydraulic push rod, it provides pushing and pulling forces to the side pressure plate, making it easy for the side pressure plate to flip upward and assemble with the mold chamber. It also makes it easy to flip the side pressure plate downward after the sound-absorbing panel is produced, so that the side pressure plate is away from the sound-absorbing panel, allowing outside air to enter the bottom of the sound-absorbing panel and avoiding excessive negative pressure between the sound-absorbing panel and the mold chamber, which would affect the demolding efficiency. Through the rotation of the eccentric wheel impacting the movable frame, the vibration is transmitted to the support plate through the movable frame and the connecting ring, making it easy for the support plate to separate from the sound-absorbing panel, improving the convenience of demolding the sound-absorbing panel.

[0017] 3. The demolding device for the sound-absorbing panel forming mold uses a buffer spring to elastically connect the impact force of the movable frame, preventing the support plate from rigidly pulling the sound-absorbing panel and causing damage. This improves the stability of the vibration of the support plate driven by the movable frame. The reducer drives the eccentric wheel to rotate at a uniform and stable speed. By reducing the speed of the power equipment, the output torque is increased, which improves the impact force of the eccentric wheel pressing the movable frame and the stability of the eccentric wheel rotation. The reducer is controlled by an electric motor, and the movement of the support frame is controlled by an electric push rod. The electric push rod is a mature technology, and this application can use existing equipment to control the lateral movement of the support frame. The support rollers reduce the friction between the support frame and the fixed base, improving the stability of the lateral sliding of the support frame. Attached Figure Description

[0026] This utility model provides a demolding device for a sound-absorbing panel forming mold.

[0027] Please see Figure 1 It includes a fixed base 1 and a mold chamber 2. A side pressure plate 4 is rotatably connected to the surface of the mold chamber 2. The side pressure plate 4 and the mold chamber 2 are combined to form a mold, which facilitates the production of sound-absorbing panels.

[0028] A support frame 3 is fixedly connected to the bottom of the mold chamber 2, and the bottom end of the support frame 3 is fixedly connected to the fixed base 1. A hydraulic push rod 5 is rotatably connected to the surface of the fixed base 1, and the output end of the hydraulic push rod 5 is rotatably connected to the side pressure plate 4. The hydraulic push rod 5 is a mature technology, and this application can use existing equipment that controls the flipping of the side pressure plate 4.

[0029] The support frame 3 supports and fixes the mold chamber 2, and the support frame 3 facilitates the maintenance and repair of the internal equipment of the mold chamber 2, improving the convenience of the device. The hydraulic push rod 5 provides pushing and pulling force to the side pressure plate 4, which makes it easy for the side pressure plate 4 to flip upward and assemble with the mold chamber 2. It also makes it easy to flip the side pressure plate 4 downward after the sound-absorbing panel is produced, so that the side pressure plate 4 is away from the sound-absorbing panel, which allows outside air to enter the bottom of the sound-absorbing panel and avoids excessive negative pressure between the sound-absorbing panel and the mold chamber 2, which affects the demolding efficiency.

[0030] Please see Figure 2 , Figure 3 and Figure 4 The mold chamber 2 is equipped with a support mechanism 6, which includes a connecting frame 602 and an eccentric wheel 606. A support plate 601 is fixedly connected to the top of the connecting frame 602, and a connecting ring 609 is fixedly connected to the bottom of the connecting frame 602. The connecting ring 609 is sleeved on the outside of the eccentric wheel 606. By rotating the eccentric wheel 606, the connecting ring 609 drives the connecting frame 602 to vibrate up and down, which in turn drives the support plate 601 to vibrate up and down, so that the support plate 601 is separated from the ground of the formed sound-absorbing panel, which facilitates the demolding operation of the produced sound-absorbing panel and improves the convenience of demolding the sound-absorbing panel.

[0031] The support plate 601 is slidably connected to the mold chamber 2. The movable frame 603 is slidably connected inside the connecting ring 609. The eccentric wheel 606 abuts against the surface of the movable frame 603. One end of the movable frame 603 is fixedly connected to the connecting plate 604. The vibration is transmitted to the support plate 601 through the rotation of the eccentric wheel 606 and the movable frame 603, and then through the movable frame 603 and the connecting ring 609. This facilitates the separation of the support plate 601 from the sound-absorbing panel and improves the ease of demolding the sound-absorbing panel.

[0032] The movable frame 603 is fitted with a buffer spring 605, and the two ends of the buffer spring 605 are fixedly connected to the connecting ring 609 and the connecting plate 604 respectively. The buffer spring 605 can elastically connect the impact force of the movable frame 603, avoid the support plate 601 rigidly pulling the sound-absorbing plate and causing damage to the sound-absorbing plate, and can transmit and amplify the vibration borne by the movable frame 603, thereby improving the stability of the vibration of the support plate 601 driven by the movable frame 603.

[0033] The eccentric wheel 606 is rotatably connected to the fixed base 1. A reducer 607 is fixedly connected to the surface of the fixed base 1, and the output end of the reducer 607 is fixedly connected to the eccentric wheel 606. The reducer 607 drives the eccentric wheel 606 to rotate at a uniform and stable speed. By reducing the speed of the power equipment, the output torque is increased, thereby increasing the impact force of the eccentric wheel 606 on the movable frame 603 and the stability of the rotation of the eccentric wheel 606.

[0034] A motor 608 is fixedly connected to the surface of the fixed base 1, and the output end of the motor 608 is fixedly connected to the input end of the reducer 607. The motor 608 controls the rotation of the reducer 607. The motor 608 is a mature technology, and this application can use existing equipment to control the rotation of the reducer 607.

[0035] Please refer to it again. Figure 2 and Figure 5 The surface of the fixed base 1 is provided with a positioning mechanism 7 for the positioning connecting ring 609. The positioning mechanism 7 includes a support frame 701 that is slidably connected to the connecting ring 609. The front end of the support frame 701 is inclined, which facilitates the support frame 701 to press the connecting ring 609 and position the connecting ring 609. The support frame 701 supports and fixes the connecting ring 609, preventing the connecting ring 609 from sliding up and down during the production of the sound-absorbing board and improving the stability of the support plate 601 during operation.

[0036] The bottom of the support frame 701 is rotatably connected to a support roller 702, and the support roller 702 is slidably connected to the fixed base 1. An electric push rod 703 is fixedly connected to the surface of the fixed base 1, and the output end of the electric push rod 703 is fixedly connected to the support frame 701. The movement of the support frame 701 is controlled by the electric push rod 703. The electric push rod 703 is a mature technology. This application can use existing equipment to control the lateral movement of the support frame 701. By using the support roller 702, the friction between the support frame 701 and the fixed base 1 is reduced, and the stability of the lateral sliding of the support frame 701 is improved.

[0037] Working principle: The hydraulic push rod 5 provides thrust to the side pressure plate 4, causing it to flip upwards and assemble with the mold chamber 2. The side pressure plate 4 and mold chamber 2 combine to form a mold, facilitating the production of the sound-absorbing panel. After the sound-absorbing panel is formed, the hydraulic push rod 5 first applies tension to the side pressure plate 4, causing it to flip downwards away from the sound-absorbing panel. Then, the electric push rod 703 controls the movement of the support frame 701, moving it away from the connecting ring 609. The motor 608 is then started, controlling the reducer 607 to rotate. 07 drives the eccentric wheel 606 to rotate at a uniform and stable speed, causing the eccentric wheel 606 to impact the movable frame 603. The impact force of the movable frame 603 can be absorbed and transferred by the buffer spring 605, causing the connecting ring 609 to drive the connecting frame 602 to vibrate up and down, which in turn drives the support plate 601 to vibrate up and down, causing the support plate 601 to detach from the formed sound-absorbing panel ground, facilitating the demolding operation of the produced sound-absorbing panel and improving the convenience of demolding the sound-absorbing panel. Through the above device, the difficulty of demolding the sound-absorbing panel is reduced and the demolding efficiency of the sound-absorbing panel is improved.
