Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a demolding device for preparing resin fiber composite materials. Background Technology

[0002] With the development of industrial manufacturing technology, resin fiber composite materials have been widely used in aerospace, automotive, construction and other fields due to their excellent mechanical properties, lightweight and high strength. In the molding process of resin fiber composite materials, demolding is a crucial step. The quality of demolding operation directly affects the surface quality of the product, production efficiency and mold life. Traditional demolding devices mostly use a single robotic arm or pneumatic or hydraulic methods for demolding.

[0003] Traditional demolding methods are prone to incomplete demolding or damage to the surface of molded parts when handling complex shapes or highly viscous parts, resulting in unstable product quality. Furthermore, excessive adhesion between the mold and the molded part during demolding leads to excessive or uneven demolding force, which in turn increases equipment wear and reduces production efficiency. Therefore, those skilled in the art provide a demolding device for the preparation of resin fiber composite materials to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a demolding device for preparing resin fiber composite materials. By incorporating a loosening component, the device enables rapid loosening of the molded part during the demolding process, reducing wear on the mold during subsequent ejection and demolding, extending the mold's service life, improving demolding efficiency, and reducing manual intervention.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a demolding device for preparing resin fiber composite materials, comprising an upper mold base, a lower mold base and a base, wherein a top material seat is fixedly connected to the upper middle part of the base, a loosening component is provided between the lower mold base and the base, and a disassembly component is provided between the lower mold base and the top material seat.

[0006] The loosening assembly includes multiple fixing brackets and two mounting plates. The multiple fixing brackets are fixedly connected to the base. A rotating shaft is rotatably connected between the opposite ends of the two fixing brackets on the same side. Two cams are fixedly sleeved on the outer walls of the two rotating shafts. A reset groove is opened at the opposite ends of the two fixing brackets on the same side. The two mounting plates are slidably disposed in the corresponding reset grooves. Multiple reset springs are fixedly connected between the multiple reset grooves and the inner walls of the opposite sides of the corresponding mounting plates. A connecting plate is fixedly connected to one side of each of the two mounting plates by multiple first fixing bolts. A tapping block is fixedly connected to the front and rear of the opposite sides of the two connecting plates. Stainless steel alloy plates are fixedly connected to both sides of the lower mold base by multiple second fixing bolts.

[0007] Through the above technical solution, by incorporating a loosening component, the rotating shaft can be controlled to rotate the corresponding cam during the demolding process. At this time, in conjunction with the provided return spring, the mounting plate can move back and forth with the tapping block. This causes the polyurethane rubber heads on the tapping block to continuously tap the stainless steel alloy plates on both sides of the lower mold base. Through continuous tapping action, the molded part can be quickly loosened, reducing wear on the mold during subsequent ejection and demolding processes, extending the mold's service life, improving demolding efficiency, and reducing manual intervention.

[0008] Furthermore, the assembly / disassembly component includes two T-shaped blocks, both of which are fixedly connected to the top material seat. T-shaped grooves are provided on both sides of the rear end of the lower mold seat. The two T-shaped blocks are slidably disposed in the corresponding T-shaped grooves. Sliding slots are provided at the rear upper end of the two T-shaped blocks. Fixed blocks are slidably disposed inside the two sliding slots. Fixed slots are provided at the rear upper inner wall of the two T-shaped grooves. The two fixed blocks are engaged in the corresponding fixed slots. Multiple movable springs are fixedly connected between the inner walls of the two fixed blocks and the corresponding sliding slots at opposite ends.

[0009] Through the above technical solution, by providing a disassembly and assembly component, the movement of the fixed block can be controlled to allow it to disengage from or engage with the fixed slot, thereby enabling the unlocking or connection and fixing of the lower mold base and the ejector base. This allows for the replacement of the lower mold base on the demolding device, and the overall operation process is simple and quick, providing convenience for operators and saving operation time.

[0010] Furthermore, a top material groove is provided in the middle of the upper end of the top material seat, and top material cylinders are fixedly provided on both sides of the lower inner wall of the top material groove. The telescopic ends of the two top material cylinders are fixedly connected to the top material plate. A movable groove is provided in the lower end of the lower mold base.

[0011] With the above technical solution, after the molded part is loosened, the ejector cylinder can be activated to move the ejector plate upward. Through the provided movable plate and connecting rod, multiple ejector blocks can be pushed upward, thereby easily ejecting the molded part from the molding cavity of the lower mold base.

[0012] Furthermore, the rear ends of the two fixed frames located at the rear are fixedly connected to a transmission box, and transmission wheels are rotatably connected between the front and rear inner walls of the transmission box on both sides. A transmission belt is provided between the outer walls of the two transmission wheels, and one end of each of the two rotating shafts passes through the corresponding fixed frame and the transmission box and is fixedly connected to the corresponding transmission wheel.

[0013] Through the above technical solution, by means of the provided transmission wheel and transmission belt, when one of the transmission wheels rotates, the other transmission wheel can be rotated, thereby enabling the two rotating shafts to rotate.

[0014] Furthermore, each of the two sliding slots has a movable groove on its rear inner wall, and a movable block is movably disposed inside each of the two movable grooves. A toggle plate is fixedly connected between the rear ends of the two movable blocks, and each of the two movable blocks is fixedly connected to a corresponding fixed block.

[0015] The above technical solution, by providing a toggle plate, allows operators to easily control the movement of the fixed block by moving the toggle plate.

[0016] Furthermore, both sides of the inner wall of the movable groove are provided with spring grooves, and spring blocks are slidably arranged inside the two spring grooves. The two spring blocks are fixedly connected to the movable plate, and multiple return springs are fixedly connected between the two spring blocks and the inner wall of the opposite end of the corresponding spring groove.

[0017] With the above technical solution, by providing a rebound block and a return spring, when the material ejection operation is completed, the movable plate can return to its original position via the rebound block and return spring, which facilitates smooth subsequent preparation.

[0018] Furthermore, a drive motor is fixedly installed on one side of the rear end of the transmission box, and the output end of the drive motor passes through the transmission box and is fixedly connected to the corresponding transmission wheel.

[0019] The above technical solution involves a drive motor, which can be activated to rotate the corresponding transmission wheel.

[0020] Furthermore, each of the multiple striking blocks is provided with a polyurethane rubber head at one end, and each of the multiple cams is provided to contact the corresponding mounting plate;

[0021] The above technical solution utilizes a polyurethane rubber head, whose softness and elasticity effectively disperse impact forces, preventing excessive local pressure on the mold and molded parts, reducing damage, and improving demolding quality.

Both sides of the lower mold base 2 are fixedly connected to stainless steel alloy plates 18 by multiple second fixing bolts 17. With the addition of a loosening component 5, during demolding, the rotating shaft 8 can be controlled to rotate the corresponding cam 9.

Fixed grooves 38 are provided at the rear upper inner wall of each of the two T-slots 35. The two fixed blocks 37 engage within their respective fixed grooves 38. Multiple movable springs 39 are fixedly connected between the two fixed blocks 37 and the inner walls of the corresponding sliding grooves 36 at opposite ends. By providing the disassembly / assembly assembly 6, the mechanism can be controlled... The fixed block 37 moves to disengage from or engage with the fixed slot 38, thereby unlocking or fixing the lower mold base 2 and the ejector base 4. This allows for the replacement of the lower mold base 2 on the demolding device. The overall operation is simple and quick, providing convenience and saving time for operators. The inner walls of the rear ends of the two sliding slots 36 are provided with moving slots 40. Moving blocks 41 are movably arranged inside the two moving slots 40. A toggle plate 42 is fixedly connected between the rear ends of the two moving blocks 41. Both moving blocks 41 are fixedly connected to the corresponding fixed block 37. The toggle plate 42 allows operators to easily control the movement of the fixed block 37 by moving the toggle plate 42.

[0037] Working principle: During the demolding process, after the upper mold base 1 is removed, the corresponding transmission wheel 31 can be rotated by starting the drive motor 33. The transmission belt 32 can then rotate another transmission wheel 31, which in turn causes the two rotating shafts 8 to rotate with their corresponding cams 9. At this time, the reset spring 16 can cause the mounting plate 11 to move back and forth with the striking block 14, so that the polyurethane rubber head 15 on the striking block 14 continuously strikes the stainless steel alloy plates 18 on both sides of the lower mold base 2. Through continuous striking action, the molded part can be quickly loosened, reducing wear on the mold during subsequent ejection and demolding, extending the mold's service life, improving demolding efficiency, and reducing manual intervention. After the molded part is loosened, the ejector cylinder 20 can be activated to eject the material. The plate 21 moves upward, and the movable plate 23 and connecting rod 24 can push the multiple ejector blocks 26 upward, so that the molded part can be easily ejected from the molding cavity of the lower mold base 2. When it is necessary to replace the lower mold base 2 to produce other types of products, the two fixing blocks 37 can be moved down and disengaged from the fixing slots 38 by pressing the actuating plate 42, so as to release the original fixing restriction between the lower mold base 2 and the ejector seat 4, and then it can be removed. During subsequent installation, the T-block 34 only needs to be smoothly inserted into the T-slot 35 on the corresponding lower mold base 2. When the fixing block 37 encounters the fixing slot 38, the movable spring 39 can make the fixing block 37 reset, pop out and insert into the fixing slot 38, so as to complete the fixed installation of the corresponding lower mold base 2.
