During the mold pressing process, pressure control is one of the key factors affecting product quality.

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.

[0022] Reference Figures 1-3 This utility model provides an embodiment of an automated mold opening and closing control device, comprising an opening and closing device body 1, an opening and closing mechanism 2 disposed inside the opening and closing device body 1, an upper mold 3 and a lower mold 4 disposed inside the opening and closing device body 1, a PLC control device 5 disposed outside the opening and closing device body 1, pressure sensors 6 disposed on the pressing surfaces of the upper mold 3 and the lower mold 4, displacement sensors 7 disposed outside the opening and closing device body 1, and a heat dissipation assembly 8 disposed outside the PLC control device 5. The pressure sensors 6 are fixedly connected to the four corners of the lower mold 4 near the upper mold 3, and are electrically connected to the PLC control device 5.

It can monitor the displacement changes of the mold in real time and accurately. It converts the displacement signal into an electrical signal and transmits it to the PLC control device 5 in a timely manner. Based on this displacement information, the PLC control device 5 accurately controls the action speed and stroke position of the opening and closing mechanism 2. This enables the upper mold 3 and the lower mold 4 to open and close according to the preset precise stroke, ensuring the accuracy and consistency of mold opening and closing.

This effectively reduces production failures and defective products caused by inaccurate mold opening and closing, greatly improves the stability and reliability of production, and reduces production costs.

[0023] Reference Figures 1-3During the operation of the PLC control device 5, a large amount of heat is generated. If it cannot be dissipated in time, the internal temperature of the device will rise, affecting the performance and stability of electronic components, and may even cause component damage and shorten the service life of the equipment. The heat dissipation holes 81 in the heat dissipation assembly 8 are opened on the bottom surface of the PLC control device 5, providing a basic channel for heat dissipation. The connecting plate 83 is mutually attracted and fixed to the bottom of the PLC control device 5 by the spiral magnetic strip 84, so that the vent 85 in the center of the connecting plate 83 is accurately connected to the heat dissipation hole 81. External air can enter the heat dissipation hole 81 through the vent 85, which dissipates heat from the PLC control device 5. The control device 5 performs initial heat dissipation. The heat dissipation pipe 86 is connected to the vent 85, allowing air to flow through the heat dissipation pipe 86 to the annular pipe 87. The annular pipe 87 is divided into an inlet pipe and an exhaust pipe by a partition 89. The drive motor 811, fixed in the center of the partition 89, drives the fan 812 to rotate. The fan 812 creates a negative pressure in the exhaust pipe, causing external air to enter from the inlet pipe at one end of the annular pipe 87. After passing through the filter screen 88 to remove impurities, the air enters the PLC control device 5 through the heat dissipation pipe 86, the vent 85, and the heat dissipation hole 81. This fresh air carries away the heat generated inside the device during its flow and then exits through the exhaust pipe. The exhaust pipes form a complete and efficient airflow circulation cooling system. The cooling component 8 includes cooling holes 81. A spiral magnetic groove 82 is provided on the bottom surface of the PLC control device 5. A connecting plate 83 is provided below the PLC control device 5. A spiral magnetic strip 84 is fixedly connected to one end of the connecting plate 83 near the PLC control device 5. A vent 85 is provided through the center of the connecting plate 83. A cooling pipe 86 is fixedly connected to the end of the connecting plate 83 away from the PLC control device 5. An annular pipe 87 is fixedly connected to the end of the cooling pipe 86 away from the connecting plate 83. Filters 88 are fixedly connected to both ends of the annular pipe 87. The internal fixed connection is a partition 89, the center of which is fixedly connected to a drive motor 811. The output shaft surface of the drive motor 811 is fixedly connected to a fan 812. The heat dissipation hole 81 is opened on the bottom surface of the PLC control device 5. The spiral magnetic strip 84 and the spiral magnetic groove 82 are mutually adapted. The vent 85 is connected to the heat dissipation hole 81. The heat dissipation pipe 86 is connected to the vent 85. The partition 89 divides the annular pipe 87 into an air inlet pipe and an air outlet pipe. The fan 812 is set inside the exhaust pipe. The end of the partition 89 away from the annular pipe 87 is flush with the vent 85. The partition 89 divides the vent 85 into an air inlet and an air outlet.

[0024] Working principle: When the automated mold opening and closing control device is working, the opening and closing mechanism 2 inside the main body 1 drives the upper mold 3 and the lower mold 4 to open and close. During the pressing operation, the upper mold 3 presses down and contacts the lower mold 4. At this time, the pressure sensors 6 located at the four corners of the lower mold 4 near the upper mold 3 will detect the pressure on the pressing surfaces in real time and convert the pressure signal into an electrical signal, which is transmitted to the external PLC control device 5. The PLC control device 5 adjusts the opening and closing mechanism 2 according to the preset pressure parameters to ensure that the pressing pressure meets the requirements. At the same time, the displacement sensor 7 covers the upper mold 3 and the lower mold. The upper mold 3 and lower mold 4 have a travel trajectory, which monitors the displacement of the upper mold 3 and lower mold 4 in real time and converts the displacement signal into an electrical signal and transmits it to the PLC control device 5. The PLC control device 5 accurately controls the action of the opening and closing mechanism 2 based on the displacement information to ensure that the upper mold 3 and lower mold 4 open and close accurately according to the set travel. During the operation of the PLC control device 5, the heat dissipation holes 81 on its bottom surface are used for heat dissipation. When dissipating heat, the loop magnetic groove 82 on the bottom surface of the PLC control device 5 and the loop magnetic strip 84 on the connecting plate 83 attract each other, fixing the connecting plate 83 below the PLC control device 5. At this time, the connecting plate 83... The vent 85 at the center of the PLC control device 5 is connected to the heat dissipation hole 81. External air can enter the heat dissipation hole 81 through the vent 85 to provide initial cooling for the PLC control device 5. At the same time, the heat dissipation pipe 86, which is fixedly connected to the end of the connecting plate 83 away from the PLC control device 5, is connected to the vent 85. Air can circulate through the heat dissipation pipe 86. The end of the heat dissipation pipe 86, which is fixedly connected to the annular pipe 87 at the end away from the connecting plate 83, is internally divided into an inlet pipe and an exhaust pipe by a partition 89. The drive motor 811, which is fixedly connected to the center of the partition 89, starts and drives the fan 812, which is fixedly connected to the surface of its output shaft, to rotate. Because the fan 812 is designed to... Placed inside the exhaust pipe, when the fan 812 rotates, it creates a negative pressure inside the exhaust pipe, causing external air to enter from the air inlet pipe at one end of the annular pipe 87. After being filtered by the filter screen 88, the air enters the PLC control device 5 through the heat dissipation pipe 86, the vent 85, and the heat dissipation hole 81, carrying away heat before being discharged from the exhaust pipe. The end of the partition plate 89 away from the annular pipe 87 is flush with the vent 85, dividing the vent 85 into an air inlet and an exhaust outlet, allowing air to circulate in an orderly manner, achieving efficient heat dissipation, ensuring the stable operation of the PLC control device 5, and thus ensuring the normal operation of the entire automated mold opening and closing control device.
