Description

Technical Field

[0001] This utility model relates to the field of PET sheet cooling and shaping devices, specifically a high-efficiency cooling and shaping device for PET sheet processing. Background Technology

[0002] PET sheets are thermoplastic environmentally friendly plastic products. After burning, they are odorless and tasteless, do not produce toxic gases, have high transparency, no water ripples on the surface, no crystal points, no directional whitening, strong resistance to oils and chemicals, high toughness and rigidity, and good impact resistance. These characteristics make PET widely used in packaging, fiber, film, engineering plastics and other fields. When processing PET sheets, a cooling and shaping device is required, and the raw material is formed by pressing the upper mold onto the lower mold.

[0003] A search revealed that Chinese utility model patent CN218615029U discloses a PET sheet hot pressing mold comprising: a lower mold, a guide rod, an upper mold, an oil tank, a PET sheet hot pressing machine, a cylinder, an oil outlet, a guide block, and an oil guide rod. The beneficial effects are: when the cylinder drives the upper mold downwards, the oil guide rod disengages from the cylinder, allowing the lubricating oil on the guide rod to flow onto the guide block, and then from the guide block to the surface of the guide rod, achieving its lubrication effect. This lubrication is completed during the operation of the PET sheet hot pressing machine, effectively improving its working efficiency and increasing the timeliness of oil application, resulting in better lubrication between the upper mold and the guide rod, and preventing excessive friction from affecting the smoothness of the upper mold's movement.

[0004] The technical solution in the application document still has shortcomings: after the PET sheet is formed, it needs to be cooled and shaped to prevent the PET sheet from deforming during the forming process. The cooling and shaping time is too long, resulting in low production efficiency. Moreover, the cooling and shaping device only has one mold structure, which is inefficient and cannot meet the needs of large-scale production. Summary of the Invention

[0005] The purpose of this invention is to provide a high-efficiency cooling and shaping device for PET sheet processing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency cooling and shaping device for PET sheet processing, comprising a cooling water tank, an upper shaping mold, a lower shaping mold, and a mounting plate. A mounting frame is mounted on the cooling water tank, and a hydraulic rod is mounted on the mounting frame. One end of the hydraulic rod is fitted with the upper shaping mold. A fixing plate is mounted on the cooling water tank, and mounting plates are installed between the fixing plates. The lower shaping mold is mounted on each of the four sides of the mounting plate. A cooling groove is formed in the lower shaping mold. A gear ring is mounted on the mounting plate. A motor is mounted in the fixing plate, and a gear is mounted on the motor's drive shaft end, meshing with the gear ring.

[0007] Using the above technical solution, after the PET material is added to the lower forming mold, the hydraulic rod on the mounting frame is activated, driving the upper forming mold to move down and close with the lower forming mold, pressing the PET material into shape. The cooling tanks in the upper and lower forming molds are filled with cooling water, which can quickly and efficiently cool and shape the PET material. After the PET sheet is shaped, the hydraulic rod drives the upper forming mold to move up, and the motor installed in the fixed plate is activated, driving the gear installed at the end of the power shaft to rotate. Because the gear meshes with the gear ring installed on the mounting plate, it drives the mounting plate to rotate, so that the other lower forming mold on the mounting plate moves directly below the hydraulic rod for the next PET sheet pressing and shaping, realizing continuous production and improving production efficiency.

[0008] Preferably, the cooling water tank is equipped with a water inlet pipe, one end of which is rotatably connected to a main water inlet channel in the mounting plate, the main water inlet channel is connected to a water inlet channel in the mounting plate, and the other end of the water inlet channel is connected to the cooling tank. The cooling water tank is also equipped with a water outlet pipe, one end of which is rotatably connected to a main water outlet channel in the mounting plate, the main water outlet channel is connected to a water outlet channel in the mounting plate, and the other end of the water outlet channel is connected to the cooling tank.

[0009] Using the above technical solution, the cold water generated in the cooling water tank flows into the main water channel through the inlet pipe, and then is evenly distributed to the cooling tanks on each lower forming mold through the water inlet channel. This effectively absorbs the heat generated by the PET sheet during the pressing and molding process, achieving rapid cooling and shaping. The water after heat exchange is collected into the main water outlet channel through the water outlet channel, and finally enters the cooling water tank through the water outlet pipe for cooling, completing the cooling cycle. This improves cooling efficiency, ensures the stability and continuity of the cooling process, and enhances the efficiency and effect of cooling and shaping.

[0010] Preferably, the cooling water tank is equipped with an inlet elastic pipe, the other end of which is connected to the cooling groove of the upper forming mold, and the cooling water tank is equipped with an outlet elastic pipe, the other end of which is connected to the cooling groove of the upper forming mold.

[0011] Using the above technical solution, cold water in the cooling water tank flows into the cooling tank of the upper shaping mold through the inlet elastic pipe, cooling the upper surface of the PET material. The cooled water then flows back to the cooling water tank through the outlet elastic pipe, forming a cooling cycle for the upper shaping mold. This design ensures that both the upper and lower shaping molds are adequately cooled, further improving the cooling and shaping effect and the quality of the PET material. Simultaneously, the elastic design of the inlet and outlet elastic pipes allows them to expand and contract with the up-and-down movement of the upper shaping mold, ensuring the stability and continuity of the cooling cycle.

[0012] Preferably, a flow-limiting plate is provided in the cooling tank.

[0013] By adopting the above technical solution, the flow restrictor extends the flow path of cooling water in the cooling tank, thereby increasing the residence time of cooling water in the cooling tank and improving the heat exchange efficiency. This ensures that the PET material can be fully and uniformly cooled during the compression molding process, thereby improving the shaping quality and production efficiency of PET sheets.

[0014] Preferably, one end of the electric telescopic rod installed on the fixed plate is matched with the limiting hole opened on the mounting plate.

[0015] Using the above technical solution, one end of the electric telescopic rod can engage with the corresponding limiting hole when the mounting plate rotates to the corresponding position, thereby limiting and fixing the mounting plate. This ensures the stability of the upper and lower shaping molds during the pressing and molding process, allowing the mounting plate to remain stable and preventing displacement that could affect the pressing effect and cooling and shaping quality of the PET material.

[0016] Preferably, the cooling water tank is equipped with water-cooling components such as a circulating pump, radiator, and water tank.

[0017] Using the above technical solution, the water-cooling components involved in the cooling water tank are all existing mature technologies, with many products on the market. They are all general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or through routine use. The content protected by this application does not involve the improvement of water-cooling components and water-cooling methods, so the model of the water-cooling components and the water-cooling process of the water-cooling components will not be described in detail here.

[0018] Compared with the prior art, the beneficial effects of this utility model are: After the PET material is added to the lower forming mold, the hydraulic rod drives the upper forming mold to move down and close with the lower forming mold, pressing the PET material into shape. The cooling tanks in the upper and lower forming molds are filled with cooling water, which can quickly and efficiently cool and shape the PET material. After the PET sheet is shaped, the hydraulic rod drives the upper forming mold to move up, and the motor installed in the fixed plate starts, driving the gear installed at the end of the power shaft to rotate. Because the gear meshes with the gear ring installed on the mounting plate, it drives the mounting plate to rotate, so that the other lower forming mold on the mounting plate moves directly below the hydraulic rod for the next PET sheet pressing and shaping, realizing continuous production and improving production efficiency.

[0019] Cold water generated in the cooling water tank flows into the main water inlet channel through the inlet pipe, and then is evenly distributed to the cooling tanks on each lower forming mold via the water inlet channel. This effectively absorbs the heat generated by the PET sheet during the compression molding process, achieving rapid cooling and shaping. The water after heat exchange is collected in the main water outlet channel through the water outlet channel, and finally enters the cooling water tank through the water outlet pipe for further cooling, completing the cooling cycle. Cold water in the cooling water tank flows into the cooling tank of the upper forming mold through the water inlet elastic pipe, cooling the upper surface of the PET material. The cooled water flows back to the cooling water tank through the water outlet elastic pipe, forming a cooling cycle for the upper forming mold. This design ensures that both the upper and lower forming molds are adequately cooled, improving the cooling and shaping effect and the quality of the PET material. Attached Figure Description

[0022] 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.

[0023] Please see Figure 1-4This utility model provides an embodiment of a high-efficiency cooling and shaping device for PET sheet processing, comprising a cooling water tank 1, an upper shaping mold 4, a lower shaping mold 9, and a mounting plate 13. A mounting frame 2 is mounted on the cooling water tank 1, and a hydraulic rod 3 is mounted on the mounting frame 2. One end of the hydraulic rod 3 is mounted to the upper shaping mold 4. A fixing plate 14 is mounted on the cooling water tank 1, and mounting plates 13 are installed between the fixing plates 14. The lower shaping mold 9 is mounted on each of the four surfaces of the mounting plate 13. A cooling groove 10 is formed in the lower shaping mold 9. A gear ring 16 is mounted on the mounting plate 13. A motor 15 is mounted in the fixing plate 14, and a gear 17 is mounted on the power shaft end of the motor 15, meshing with the gear ring 16. After the PET material is added to the lower forming mold 9, the hydraulic rod 3 on the mounting frame 2 is activated, driving the upper forming mold 4 to move down and close with the lower forming mold 9, pressing the PET material into shape. The cooling tanks 10 in the upper forming mold 4 and the lower forming mold 9 are filled with cooling water, which can quickly and efficiently cool and shape the PET material. After the PET sheet is shaped, the hydraulic rod 3 drives the upper forming mold 4 to move up, and the motor 15 installed in the fixed plate 14 is activated, driving the gear 17 installed at the end of the power shaft to rotate. Because the gear 17 meshes with the gear ring 16 installed on the mounting plate 13, it drives the mounting plate 13 to rotate, so that the other lower forming mold 9 on the mounting plate 13 moves directly below the hydraulic rod 3 for the next PET sheet pressing and shaping, realizing continuous production and improving production efficiency.

[0024] The cooling water tank 1 is equipped with an inlet pipe 11. One end of the inlet pipe 11 is rotatably connected to the main water inlet channel 12 opened in the mounting plate 13. The main water inlet channel 12 is connected to the water inlet channel 8 opened in the mounting plate 13. The other end of the water inlet channel 8 is connected to the cooling tank 10. The cooling water tank 1 is equipped with an outlet pipe 18. One end of the outlet pipe 18 is rotatably connected to the main water outlet channel 19 opened in the mounting plate 13. The main water outlet channel 19 is connected to the water outlet channel 20 opened in the mounting plate 13. The other end of the water outlet channel 20 is connected to the cooling tank 10. The cold water generated in the cooling water tank 1 flows into the main water inlet channel 12 through the water inlet pipe 11, and then is evenly distributed to the cooling tanks 10 on each lower shaping mold 9 through the water inlet channel 8. This effectively absorbs the heat generated by the PET sheet during the pressing and molding process, achieving rapid cooling and shaping. The water after heat exchange is collected into the main water outlet channel 19 through the water outlet channel 20, and finally enters the cooling water tank 1 through the water outlet pipe 18 for cooling, completing the cooling cycle, improving cooling efficiency, ensuring the stability and continuity of the cooling process, and improving the efficiency and effect of cooling and shaping.

[0025] A water inlet elastic pipe 6 is installed on the cooling water tank 1, with the other end of the water inlet elastic pipe 6 connected to the cooling tank of the upper shaping mold 4. A water outlet elastic pipe 7 is also installed on the cooling water tank 1, with the other end of the water outlet elastic pipe 7 connected to the cooling tank of the upper shaping mold 4. Cold water in the cooling water tank 1 flows into the cooling tank of the upper shaping mold 4 through the water inlet elastic pipe 6, cooling the upper surface of the PET material. The cooled water then flows back into the cooling water tank 1 through the water outlet elastic pipe 7, forming a cooling cycle for the upper shaping mold 4. This design ensures that both the upper shaping mold 4 and the lower shaping mold 9 are adequately cooled, further improving the cooling and shaping effect and the quality of the PET material. Simultaneously, the elastic design of the water inlet elastic pipe 6 and the water outlet elastic pipe 7 allows them to expand and contract with the up-and-down movement of the upper shaping mold 4, ensuring the stability and continuity of the cooling cycle.

[0026] A flow-limiting plate 5 is provided in the cooling tank 10. The flow-limiting plate 5 extends the flow path of the cooling water in the cooling tank 10, thereby increasing the residence time of the cooling water in the cooling tank 10, thus improving the heat exchange efficiency and ensuring that the PET material can be fully and uniformly cooled during the compression molding process, thereby improving the shaping quality and production efficiency of the PET sheet.

[0027] One end of the electric telescopic rod installed on the fixed plate 14 engages with the limiting hole opened on the mounting plate 13. When the mounting plate 13 rotates to the corresponding position, one end of the electric telescopic rod engages with the corresponding limiting hole, thereby limiting and fixing the mounting plate 13. This ensures the stability of the upper forming mold 4 and the lower forming mold 9 when they are closed for pressing and molding, allowing the mounting plate 13 to remain stable and preventing displacement that would affect the pressing effect and cooling and shaping quality of the PET material.

[0028] The cooling water tank 1 is equipped with water-cooling components such as a circulating pump, radiator, and water tank. All water-cooling components involved in the cooling water tank 1 are existing mature technologies, with many products available on the market. They are all general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional use. The scope of protection in this application does not involve improvements to the water-cooling components or water-cooling methods; therefore, further detailed descriptions of the models of the water-cooling components and the water-cooling process are not provided here.

[0029] Working principle: After the PET material is added to the lower forming mold 9, the hydraulic rod 3 on the mounting frame 2 is activated, driving the upper forming mold 4 to move down and close with the lower forming mold 9, pressing and shaping the PET material. The cold water generated in the cooling water tank 1 flows into the main water inlet channel 12 through the water inlet pipe 11, and then is evenly distributed to the cooling tanks 10 on each lower forming mold 9 through the water inlet channel 8, effectively absorbing the heat generated by the PET sheet during the pressing and shaping process, achieving rapid cooling and shaping. The water after heat exchange is collected into the main water outlet channel 19 through the water outlet channel 20, and finally enters the cooling water tank 1 through the water outlet pipe 18 for cooling, completing the cooling cycle. The cold water in the cooling water tank 1 flows into the cooling tank of the upper forming mold 4 through the water inlet elastic pipe 6, cooling the upper surface of the PET material. Cooling is achieved by returning the cooled water to the cooling water tank 1 through the outlet elastic pipe 7, forming a cooling cycle for the upper shaping mold 4. This design ensures that both the upper shaping mold 4 and the lower shaping mold 9 are adequately cooled, improving the cooling and shaping effect and the quality of the PET material. It enables rapid and efficient cooling and shaping of the PET material. After the PET sheet is shaped, the hydraulic rod 3 moves the upper shaping mold 4 upward, and the motor 15 installed in the fixed plate 14 starts, driving the gear 17 installed at the end of the power shaft to rotate. Because the gear 17 meshes with the gear ring 16 installed on the mounting plate 13, it drives the mounting plate 13 to rotate, causing the other lower shaping mold 9 on the mounting plate 13 to move directly below the hydraulic rod 3 for the next PET sheet pressing and molding, realizing continuous production and improving production efficiency.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
