Description

Technical Field

[0001] This utility model relates to the field of board foaming technology, and in particular to a board foaming mold with adjustable edge guards. Background Technology

[0002] In the modern panel processing industry, foaming molding technology is widely used in the manufacturing of insulation materials, composite panels, and other products. As a core molding device, the structure and adjustability of the foaming mold directly affect the quality of the panels, production efficiency, and the mold's applicability. With the increasing market demand for multi-specification and customized panels, traditional fixed foaming molds can no longer meet diverse production needs. Therefore, a mold structure capable of flexibly adjusting the cavity size is needed to adapt to the production of panels with different widths and thicknesses. "A panel foaming mold with adjustable sidewalls" has emerged to address this need. Through a movable sidewall structure and modular upper mold design, it enables rapid adjustment of the foaming cavity size and efficient replacement of the upper mold, significantly improving the mold's versatility and production efficiency.

[0003] Existing foaming molds for sheet materials mostly employ integral welded or cast structures. The foaming cavity typically consists of a closed space formed by fixed side plates and a bottom plate. The technical principle relies on the rigid configuration of the mold. After the foaming material is injected, it expands and solidifies within the mold cavity through heating or pressurization. In common structures, the side guards are often welded and fixed, connected to the base by bolts or clips. The upper mold is usually fixed to the lower mold by multiple sets of bolts, and mold closing and pressure holding are achieved through hydraulic or mechanical pressure mechanisms.

[0004] However, existing foaming molds have a significant problem: due to the fixed structure of the baffles, the lateral dimensions of the foaming cavity cannot be flexibly adjusted according to the width of the sheet material. Therefore, when producing sheets of different widths, the entire mold or at least some baffle components must be replaced. This process is not only cumbersome and time-consuming, leading to low production efficiency, but also increases the purchase and maintenance costs of the mold. This severely restricts production flexibility and economy, especially in small-batch, multi-variety production scenarios. To address this issue, a sheet foaming mold with adjustable baffles is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a board foaming mold with adjustable baffles, which aims to improve the problem that the baffles are fixed in the prior art and cannot flexibly adjust the lateral dimensions of the foaming cavity according to the width of the board.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A foaming mold for sheet metal with adjustable baffles includes a support frame, a support column fixedly connected to the top of the support frame, a hydraulic cylinder mounted on the top of the support column, a pressure plate slidably connected to the outer wall of the support column, a pressure plate fixedly connected to the output end of the hydraulic cylinder, a connecting plate at the bottom of the pressure plate, an upper mold fixedly connected to the bottom of the connecting plate, a foaming cavity inside the support frame, two baffles slidably connected inside the foaming cavity, sliding rods fixedly connected to the side walls of the baffles, and an adjustment component at one end of each sliding rod. The adjustment assembly includes a connecting block and a connecting rod. The connecting block is fixedly connected to the outer wall of one end of the sliding rod, and the outer wall of the connecting rod is fixedly connected to the inner wall of the connecting block. A double-headed cylinder is fixedly connected to the bottom of the support frame, and one end of each connecting rod is fixedly connected to the output end of the double-headed cylinder. A connecting assembly is provided inside the connecting plate.

[0007] As a further description of the above technical solution: The connecting component includes a card frame, the outer wall of which is fixedly connected to the inside of the connecting plate.

[0008] As a further description of the above technical solution: The pressure plate is fixedly connected to a fixed frame, and a rotating column is slidably connected inside the fixed frame.

[0009] As a further description of the above technical solution: A locking post is fixedly connected to the bottom of the rotating column, and the locking post engages with the locking frame.

[0010] As a further description of the above technical solution: A ring is fixedly connected to the outer wall of the rotating column, and a limit sleeve is fixedly connected to the inner wall of the fixed frame.

[0011] As a further description of the above technical solution: The circular ring is slidably connected to the inner wall of the limiting sleeve, and the inner wall of the limiting sleeve is slidably connected to a sliding ring.

[0012] As a further description of the above technical solution: The rotating column is rotatably connected inside the sliding ring, and the sliding ring is in contact with the circular ring.

[0013] As a further description of the above technical solution: A spring is fitted on the outer wall of the rotating column. One end of the spring is fixedly connected to the bottom of the sliding ring, and the other end of the spring is fixedly connected to the inner wall of the fixed frame.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the output end of the double-headed cylinder fixed at the bottom of the support frame drives the connecting rod to move. Then, the connecting rod drives the connecting block fixedly connected to it to move. The connecting block then drives the sliding rod fixed on the inner wall to move. The sliding rod then drives the baffle that is slidably connected inside the foaming cavity to move synchronously. This adjusts the size of the space inside the foaming cavity, thereby achieving the effect of adapting to the foaming production of boards of different widths. This solves the problem of the traditional mold needing to be frequently changed to adapt to boards of different widths, improves the production flexibility and applicability of the mold, and increases production efficiency.

[0015] 2. In this utility model, pressing the rotating column in the fixed frame inside the pressure plate causes the locking column to move downward. Then, rotating the rotating column adjusts the position of the locking column. After releasing the rotating column, the spring sleeved on the outer wall of the rotating column releases its elastic force, causing the sliding ring to move upward. The sliding ring pushes the ring and rotating column that are in contact with it to move upward, thereby making the locking column engage with the locking frame fixed inside the connecting plate. This enables the quick replacement and installation of upper molds of different sizes, thereby achieving the effect of adapting to the foaming production of sheets of different thicknesses. It solves the problems of cumbersome upper mold replacement and poor adaptability in traditional molds, and improves the versatility of the mold and the convenience of upper mold replacement.

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.

[0019] Reference Figure 1 - Figure 5 This utility model provides an embodiment of a sheet foaming mold with adjustable baffles, including a support frame 1, which constitutes the main load-bearing frame of the entire device. A support column 2 is fixedly connected to the top of the support frame 1 to provide vertical support and guidance. A hydraulic cylinder 4 is provided at the top of the support column 2, serving as the main power source to drive the upper mold part to perform mold closing and opening actions. A pressure plate 3 is slidably connected to the outer wall of the support column 2, allowing the pressure plate 3 to slide stably up and down along the support column 2. The top of the pressure plate 3 is fixedly connected to the output end of the hydraulic cylinder 4 for direct connection. The hydraulic cylinder 4 provides power. The bottom of the pressure plate 3 is equipped with a connecting plate 5, which serves to connect and transmit force. The bottom of the connecting plate 5 is fixedly connected to the upper mold 6, which directly participates in the foaming process of the board. The support frame 1 has a foaming cavity 7 inside, which is the main space for containing foaming raw materials and completing foaming. Two baffles 9 are slidably connected inside the foaming cavity 7 to form the side wall of the foaming cavity 7 and change its width. The side wall of the baffles 9 is fixedly connected to a sliding rod 8 to transmit the movement of the baffles 9 to the outside. One end of the sliding rod 8 is equipped with an adjustment component. The adjustment assembly includes a connecting block 10 and a connecting rod 11. The connecting block 10 is fixedly connected to the outer wall of one end of the sliding rod 8, and is used to transfer the movement of the connecting rod 11 to the sliding rod 8. The outer wall of the connecting rod 11 is fixedly connected to the inner wall of the connecting block 10, and is used to transmit the linear motion output by the double-headed cylinder 12. The bottom of the support frame 1 is fixedly connected to the double-headed cylinder 12, which serves as the driving source for adjusting the width and can synchronously control the two baffles 9 to move in opposite directions. One end of the connecting rod 11 is fixedly connected to the output end of the double-headed cylinder 12, so that the linear thrust of the cylinder is directly transmitted to the connecting rod 11. The connecting plate 5 is provided with a connecting assembly for realizing the quick installation and replacement of the upper mold 6.

[0020] Reference Figure 1 - Figure 5The connecting assembly includes a retaining frame 14, which forms a rigid connection with the connecting plate 5 as the fixed part to provide a stable locking base. The outer wall of the retaining frame 14 is fixedly connected to the inside of the connecting plate 5. A fixing frame 13 is fixedly connected inside the pressure plate 3 to provide support and guiding space for the entire connection operation. A rotating column 16 is slidably connected inside the fixing frame 13, allowing it to slide up and down and rotate axially to adjust its position. A retaining post 19 is fixedly connected to the bottom of the rotating column 16 for directly performing the locking and disengaging actions with the retaining frame 14. The retaining post 19 engages with the retaining frame 14, thereby realizing the rapid connection and fixation between the upper mold 6 and the pressure plate 3. A ring 17 is fixedly connected to the outer wall of the rotating column 16, serving as the pushing contact surface of the sliding ring 18 and the transmission component for up and down movement. A limit sleeve 1 is fixedly connected to the inner wall of the fixing frame 13. 5. To limit the movement trajectory of the ring 17 and the sliding ring 18 and prevent deflection, the ring 17 is slidably connected to the inner wall of the limiting sleeve 15, and the inner wall of the limiting sleeve 15 is slidably connected to the sliding ring 18, which serves as a force-bearing component and transmits the force to the ring 17 and the rotating column 16. The rotating column 16 is rotatably connected inside the sliding ring 18, so that the rotating column 16 can rotate freely inside the sliding ring 18 to adjust the angle of the locking column 19. The sliding ring 18 fits against the ring 17 so that the upward movement of the sliding ring 18 can directly push the ring 17 and the rotating column 16 to rise as a whole. The outer wall of the rotating column 16 is fitted with a spring 20, which provides elastic force to reset the sliding ring 18 and the rotating column 16 to maintain the locking state. One end of the spring 20 is fixedly connected to the bottom of the sliding ring 18, and the other end of the spring 20 is fixedly connected to the inner wall of the fixing frame 13.

[0021] Working principle: First, when adjusting the width of the foaming cavity 7, the output end of the double-headed cylinder 12 fixed at the bottom of the support frame 1 drives the connecting rod 11 to move. The connecting rod 11 drives the connecting block 10 fixedly connected to its outer wall to move. The connecting block 10 drives the sliding rod 8 fixedly connected to its inner wall to move. The sliding rod 8 drives the two baffles 9 slidably connected inside the foaming cavity 7 of the support frame 1 to move synchronously, thereby adjusting the internal space of the foaming cavity 7 to adapt to the width of the target board. When changing the upper mold 6, the rotating column 16 in the fixed frame 13 fixedly connected inside the pressure plate 3 is pressed. The rotating column 16 drives the bottom fixedly connected locking column 19 to move down. At the same time, the ring 17 fixedly connected to the outer wall of the rotating column 16 slides along the inner wall of the limiting sleeve 15 fixedly connected to the inner wall of the fixed frame 13, and the rotating column 16 slides along the inner wall of the limiting sleeve 15 fixedly connected to the inner wall of the fixed frame 13. The sliding ring 18, which is internally connected to the sliding plate 5, rotates internally. After rotating and adjusting the position of the locking post 19, the rotating post 16 is released. The spring 20 sleeved on the outer wall of the rotating post 16 releases its elastic force. One end of the spring 20 pushes the sliding ring 18 to move upward. The sliding ring 18 pushes the ring 17 that is in contact with it to move upward. The ring 17 drives the rotating post 16 to move upward. The rotating post 16 drives the locking post 19 to move upward and engage with the locking frame 14 that is fixedly connected inside the connecting plate 5, thus completing the installation of the upper mold 6. Finally, during the foaming operation, the output end of the hydraulic cylinder 4 set at the top of the support column 2 drives the pressure plate 3 to slide downward along the outer wall of the support column 2. The pressure plate 3 drives the connecting plate 5 set at the bottom to move downward. The connecting plate 5 drives the upper mold 6 fixedly connected at the bottom to move downward into the foaming chamber 7, forming a sealed chamber with the baffle 9, thus realizing the foaming and molding of the board.
