Description

Technical Field

[0001] This utility model relates to the technical field of anti-warping structure for composite material Tray molds, and particularly to an anti-warping structure for composite material Tray molds. Background Technology

[0002] The anti-warping structure of the composite material tray mold is designed to address the problem of warping caused by uneven cooling, stress concentration, and unbalanced molding pressure in composite materials (such as fiber-reinforced plastics and multi-layer composite resins) during the molding process. The core of the design is to ensure the stability of the shape of the tray (pallet-type products) after molding through a triple mechanism of "precise temperature control + structural constraint + uniform force".

[0003] Existing anti-warping structures for composite material tray molds may not be able to incorporate cooling coils inside the die, preventing sufficient contact between the coiled structure of the cooling coils and the die and internal composite material. Consequently, uniform heat absorption is impossible. Furthermore, the cooled water absorbed by the cooling coils cannot be cooled and returned to the water tank, nor can the cooled water be reused inside the cooling coils. As a result, the anti-warping structure lacks both a core component for uniform heat absorption and sustainable cooling power. Therefore, we propose an anti-warping structure for composite material tray molds. Utility Model Content

[0004] The purpose of this invention is to provide an anti-warping structure for a composite material tray mold, in order to solve the problems mentioned in the background art, such as the inability to install a cooling coil inside the die, the inability to achieve sufficient contact between the coiled structure of the cooling coil and the die and the internal composite material, thus failing to achieve uniform heat absorption, the inability to cool the water absorbed by the cooling coil and return it to the water tank, and the inability to reuse the cooled water after it has entered the cooling coil. As a result, the anti-warping structure lacks both a core component for uniform heat absorption and a sustainable cooling power.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-warping structure for a composite material Tray mold, comprising a working plate and a punch, a fixing frame being provided on the top of the working plate, a concave mold being provided on the top of the working plate and below the fixing frame, an anti-warping component being provided on the top of the working plate, the anti-warping component comprising a circulating pump, a water pumping pipe, and a condensate tank, the circulating pump being connected to a cooling spiral pipe via a water supply pipe, the cooling spiral pipe being connected to a cooling spiral pipe via an L-shaped pipe, and the cooling spiral pipe being connected to a cooling water tank via a return pipe.

[0006] As a preferred embodiment, the circulating pump is fixedly installed on the top of the working plate and located on the rear side of the die. One end of the water supply pipe is fixedly connected to the output end of the circulating pump, and the other end of the water supply pipe is fixedly connected to the inside of the cooling coil tube, which is located inside the die.

[0007] As a preferred embodiment, one end of the L-shaped tube is fixedly connected to the inside of the cooling coil tube, and the other end of the L-shaped tube is fixedly connected to the inside of the cooling spiral tube. The cooling spiral tube is located inside the condensate tank, and the condensate tank is fixedly installed on the top front side of the working plate.

[0008] As a preferred embodiment, one end of the return pipe is fixedly connected to the inside of the cooling spiral tube, and the other end of the return pipe is fixedly connected to the inside of the cooling water tank. The cooling water tank is fixedly installed on the top right side of the working plate. One end of the pumping pipe is fixedly connected to the inside of the cooling water tank, and the other end of the pumping pipe is fixedly connected to the input end of the circulating pump.

[0009] As a preferred embodiment, the top of the fixing frame is provided with a driving assembly, the driving assembly includes a hydraulic rod, the hydraulic rod is fixedly installed on the top of the fixing frame, the lower end of the hydraulic rod is fixedly connected to a connecting plate, and the punch is fixedly installed on the bottom of the connecting plate.

[0010] As a preferred embodiment, a slider is fixedly connected to the side of the connecting plate, and guide posts are fixedly connected to the four corners of the bottom of the connecting plate. A sliding groove is provided on the inner side wall of the fixing frame, and the slider is slidably connected to the inside of the sliding groove. Guide cylinders are fixedly connected to the four corners of the outer wall of the die, and the four sets of guide posts are slidably connected to the inside of the four sets of guide cylinders respectively.

[0011] The technical effects and advantages of this utility model are as follows: 1. Through the anti-warping components, the circulating pump draws cooling water from the cooling water tank through the pumping pipe and delivers it to the cooling spiral tube inside the die through the water delivery pipe. The cooling spiral tube fully contacts the die and the internal composite material through the spiral structure, uniformly absorbing heat and preventing the Tray from generating internal stress due to local overheating. After absorbing heat, the cooling water enters the cooling spiral tube in the condensate tank through the L-shaped pipe. The spiral structure increases the heat exchange area and quickly reduces the water temperature. Finally, it flows back to the cooling water tank through the return pipe to complete the circulation. The entire cooling process covers the entire stage of Tray molding, with high cooling uniformity, which can effectively suppress warping deformation of composite material Trays caused by uneven cooling and improve the molding qualification rate. 2. Through the set drive components, the hydraulic rod drives the connecting plate and punch to move up and down precisely via the piston rod. The hydraulic pressure can be adjusted as needed to provide uniform and sufficient driving force for the punch to close and extrude the material, ensuring that the material fits the cavity of the die, avoiding incomplete forming of the edges and corners of the tray and ensuring its structural integrity. At the same time, the sliding block on the side of the connecting plate slides into the groove of the fixing frame, which can limit the lateral displacement of the punch. The bottom guide post slides into the guide cylinder of the die, constraining the vertical trajectory. The combination of dual guidance and hydraulic drive can ensure precise closing of the punch and die, avoiding uneven wall thickness of the tray or damage to the mold, further improving the forming accuracy and achieving the dual guarantee of sufficient power and precise guidance.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0015] Please see the appendix Figure 1 Appendix Figure 3 and appendix Figure 4An anti-warping structure for a composite material tray mold includes a working plate 1 and a punch 4. A fixing frame 2 is provided on the top of the working plate 1, and a concave mold 3 is provided on the top of the working plate 1 and below the fixing frame 2. An anti-warping component 5 is provided on the top of the working plate 1. The anti-warping component 5 includes a circulating pump 501, a water pumping pipe 508, and a condensate tank 509. The circulating pump 501 is connected to a cooling spiral pipe 503 through a water supply pipe 502. The cooling spiral pipe 503 is connected to a cooling spiral pipe 505 through an L-shaped pipe 504. The cooling spiral pipe 505 is connected to a cooling water tank 507 through a return pipe 506.

[0016] The concave mold 3 is located on top of the work plate 1 and below the fixed frame 2. It is the molding cavity component for the composite material Tray. Its internal contour matches the shape of the Tray. The composite material is shaped in the concave mold 3. At the same time, it provides installation space for the cooling coil 503 in the anti-warping component 5, realizing synchronous cooling during the molding process. The punch 4, as one of the core molding components of the mold, works in conjunction with the concave mold 3. When the mold is closed, the punch 4 extrudes the composite material into the concave mold 3, so that the material fits the cavity of the concave mold 3 to form the shape of the Tray, ensuring the structural integrity and dimensional accuracy of the Tray.

[0017] The circulating pump 501 is fixedly installed on the top of the working plate 1 and located on the rear side of the die 3. One end of the water supply pipe 502 is fixedly connected to the output end of the circulating pump 501, and the other end of the water supply pipe 502 is fixedly connected to the inside of the cooling spiral pipe 503. The cooling spiral pipe 503 is located inside the die 3. One end of the L-shaped pipe 504 is fixedly connected to the inside of the cooling spiral pipe 503, and the other end of the L-shaped pipe 504 is fixedly connected to the inside of the cooling spiral pipe 505. The cooling spiral pipe 505 is located inside the condensate tank 509, and the condensate tank 509 is fixedly installed on the top front side of the working plate 1.

[0018] The cooling coil tube 503 is located inside the cavity mold 3 and is the core component that allows the cooling medium to directly act on the formed tray part. When the cooling medium flows in the cooling coil tube 503, it exchanges heat with the cavity mold 3 and the internal composite material through the tube wall, absorbs the heat generated during the material forming process, reduces the material temperature, and avoids local overheating that could cause the tray part to warp. The coil structure design can increase the heat exchange area and improve the uniformity of cooling.

[0019] One end of the return pipe 506 is fixedly connected to the inside of the cooling spiral pipe 505, and the other end of the return pipe 506 is fixedly connected to the inside of the cooling water tank 507. The cooling water tank 507 is fixedly installed on the top right side of the working plate 1. One end of the water pump 508 is fixedly connected to the inside of the cooling water tank 507, and the other end of the water pump 508 is fixedly connected to the input end of the circulating pump 501.

[0020] The condensate tank 509 is fixedly installed on the top front side of the working plate 1. It is filled with condensate and provides a low-temperature environment for the cooling spiral tube 505. Through the heat exchange between the cooling environment inside the tank and the cooling spiral tube 505, the temperature of the medium inside the tube is rapidly reduced. It is a key cooling carrier for the recycling of cooling medium.

[0021] Specifically, through the anti-warping component 5, the circulating pump 501 draws cooling water from the cooling water tank 507 through the pumping pipe 508 and delivers it to the cooling spiral pipe 503 inside the die 3 via the water delivery pipe 502. The cooling spiral pipe 503 fully contacts the die 3 and the internal composite material through the spiral structure, absorbing heat and preventing the Tray from generating internal stress due to local overheating. The cooled water after absorbing heat enters the cooling spiral pipe 505 in the condensate tank 509 through the L-shaped pipe 504. The spiral structure increases the heat exchange area and lowers the water temperature. Finally, it flows back to the cooling water tank 507 through the return pipe 506 to complete the circulation. The entire cooling process covers the entire stage of Tray molding, with high cooling uniformity, which can suppress warping deformation of composite material Trays caused by uneven cooling and improve the molding qualification rate.

[0022] Please see the appendix Figure 1 Appendix Figure 2 and appendix Figure 5 The top of the fixed frame 2 is provided with a drive assembly 6, which includes a hydraulic rod 601. The hydraulic rod 601 is fixedly installed on the top of the fixed frame 2. The lower end of the hydraulic rod 601 is fixedly connected to a connecting plate 602. The punch 4 is fixedly installed on the bottom of the connecting plate 602. The side of the connecting plate 602 is fixedly connected to a slider 603. The bottom four corners of the connecting plate 602 are all fixedly connected to guide posts 604. The inner side wall of the fixed frame 2 is provided with a sliding groove 605. The slider 603 is slidably connected to the inside of the sliding groove 605. The outer wall of the die 3 is fixedly connected to the four corners of the guide cylinder 606. The four sets of guide posts 604 are slidably connected to the inside of the four sets of guide cylinders 606 respectively.

[0023] The lower end of the connecting plate 602 is fixedly connected to the punch 4, the side is fixedly connected to the slider 603, and the four corners of the bottom are connected to the guide posts 604. As an intermediate connecting carrier, it evenly transmits the driving force of the hydraulic rod 601 to the punch 4, avoiding uneven force on the punch 4 and deformation. At the same time, it integrates the slider 603 and the guide posts 604, so that the punch 4 can obtain multi-directional guiding constraints synchronously when it rises and falls, thus improving the stability of the movement.

[0024] Specifically, through the set drive component 6, the hydraulic rod 601 drives the connecting plate 602 and the punch 4 to rise and fall through the extension and retraction of the piston rod. The hydraulic pressure can be adjusted as needed to provide driving force for the punch 4 to close and extrude the material, ensuring that the material fits the cavity of the die 3, avoiding incomplete forming of the corners of the tray and ensuring its structural integrity. At the same time, the side slider 603 of the connecting plate 602 slides into the groove 605 of the fixing frame 2 to limit the lateral displacement of the punch 4, and the bottom guide post 604 slides into the guide cylinder 606 of the die 3 to constrain the vertical trajectory. The combination of dual guidance and hydraulic drive ensures that the punch 4 and the die 3 close, avoids uneven wall thickness of the tray or damage to the mold, improves forming accuracy, and achieves the dual guarantee of sufficient power and precise guidance.

[0025] The working principle of this utility model is as follows: This utility model is an anti-warping structure for a composite material tray mold. First, the operator places the composite material raw material into the cavity of the concave mold 3, checks the connection status of the fixing frame 2, the anti-warping component 5, and the drive component 6 on the working plate 1, and confirms that the cooling water tank 507 has been filled with sufficient cooling water and the condensate tank 509 has been filled with condensate. Then, the operator starts the hydraulic rod 601, which drives the connecting plate 602 and the bottom punch 4 to descend synchronously through the downward extension and retraction of the piston rod. At the same time, the hydraulic pressure of the hydraulic rod 601 is adjusted as needed according to the characteristics of the composite material. During the descent, the connecting plate 602... The slider 603 on the side slides along the groove 605 on the inner wall of the fixing frame 2, restricting the lateral displacement of the punch 4. The guide posts 604 at the four corners of the bottom of the connecting plate 602 correspond to the guide cylinders 606 that slide into the outer wall of the die 3, constraining the vertical movement trajectory of the punch 4. The punch 4 continues to descend to the top of the cavity of the die 3, applying a squeezing force to the composite material inside the cavity, making the material tightly adhere to the inner wall of the cavity of the die 3, forming the preliminary shape of the tray part, and avoiding incomplete forming of the edges and corners of the tray part. While the mold is being closed and squeezed, the operator can start the circulation pump 501, which draws cooling water from the cooling water tank 507 through the water pumping pipe 508. Cooling water is delivered to the cooling coil 503 inside the die 3 via water pipe 502. The cooling water flows within the cooling coil 503, exchanging heat with the die 3 and the internal composite material through the pipe wall, absorbing the heat generated during the molding process. This prevents internal stress caused by localized overheating in the tray. The cooled water, now at a higher temperature, flows through L-shaped pipe 504 into the cooling spiral pipe 505 inside the condensate tank 509. The cooling spiral pipe 505, with its spiral structure, increases the heat exchange area with the condensate in the condensate tank 509, rapidly reducing the cooling water temperature. The cooled water then flows back to the cooling water tank 507 via return pipe 506. A cooling cycle is completed, which covers the entire process of the tray part molding, ensuring uniform cooling of the tray part and suppressing warping deformation caused by uneven cooling. After the tray part is cooled and molded, the operator controls the hydraulic rod 601. The piston rod of the hydraulic rod 601 extends and retracts upward, driving the connecting plate 602 and the punch 4 to rise synchronously. During the rising process, the slider 603 returns to its original position along the slide groove 605 and the guide post 604 along the guide cylinder 606 until the punch 4 is completely separated from the die 3. Finally, the operator turns off the circulation pump 501 and removes the molded composite material tray part from the cavity of the die 3, completing a single operation.

[0026] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
