[0034] Die casting machine is a mechanical device used to manufacture metal parts. It heats the metal material (usually aluminum, zinc, magnesium, etc.) to liquid state, then injects it into a pre-designed mold, fills the cavity in the mold with high pressure, and forms the desired part shape after cooling.

[0035] A die-casting machine is usually composed of an injection system, a pressure system, a heat preservation system and a control system. The control system generally includes a control panel, and the staff controls the die-casting machine by adjusting various parameters on the control panel. However, since most of the control panels of die-casting machines on the market are located in a fixed position on one side of the die-casting machine body, it is very inconvenient for tall or short staff to operate the control panel.

[0036] In order to solve the above problems, the utility model proposes an adaptive lifting screen, which aims to provide a lifting screen that can adaptively adjust the height according to the height of the user. Figures 1 to 3 The present invention is a schematic structural diagram of an embodiment of the adaptive lifting screen provided by the present invention.

[0037] Please refer to Figures 1 to 3 The utility model proposes an adaptive lifting screen 1000, including a base 1, a driving mechanism 2, a control panel 3, a detection module 4 and a control module 5. The driving mechanism 2 is arranged on the base 1, and the driving mechanism 2 has a movable end. The control panel 3 is arranged at the movable end and can be lifted and lowered relative to the base 1. The detection module 4 is arranged at the edge of the control panel 3. The control module 5 is electrically connected to the detection module 4 and the driving mechanism 2. The control module 5 is used to identify the height of a person and control the lifting and lowering of the driving mechanism 2.

[0038] In the technical solution of the utility model, an adaptive lifting screen 1000 and a die-casting machine are proposed, wherein the adaptive lifting screen 1000 includes a base 1, a driving mechanism 2, a control panel 3, a detection module 4 and a control module 5. The detection module 4 forms a detection area in front of the control panel 3. When the detection module 4 recognizes that someone is in the detection area, it will convert the information into an electrical signal to instruct the control module 5 to identify the height of the person in the detection area. After the control module 5 completes the recognition, it will control the driving mechanism 2 according to the height of the person. The driving mechanism 2 adjusts the height of the control panel 3 according to the value transmitted by the control module 5, so that the height of the control panel 3 adapts to the height of the person. This avoids the inconvenience of users of different heights using the device and facilitates the use of users of different heights.

[0039] In order to realize the automatic lifting of the control panel 3, the driving mechanism 2 includes a fixed support rod 21, a hydraulic telescopic rod 22, an oil tank 23 and a motor synchronous linkage mechanism 24. For details, please refer to Figure 1 One end of the fixed support rod 21 is connected to the control panel 3, and the other end of the fixed support rod 21 is connected to the hydraulic telescopic rod 22. The motor synchronous linkage mechanism 24 drives the oil tank 23 to pump oil under the control of the control module 5 to push the hydraulic telescopic rod 22 up and down. It should be noted that the driving mechanism 2 can be a hydraulic telescopic mechanism or a scissor lift. The utility model does not limit this. In one embodiment of the utility model, the driving mechanism 2 includes a hydraulic telescopic rod 22 and a motor synchronous linkage mechanism 24. For details, please refer to Figure 1 One end of the hydraulic telescopic rod 22 is arranged on the base 1, and the other end is arranged on the screen base. The hydraulic telescopic rod 22 is located in the piston cavity 11a. The motor synchronous linkage mechanism 24 is arranged on the base 1. The driving end of the motor synchronous linkage mechanism 24 is connected to the hydraulic telescopic rod 22. The oil in the oil tank 23 is pumped into the hydraulic telescopic rod 22 through the motor synchronous linkage mechanism 24, thereby providing hydraulic pressure to drive the telescopic rod to rise or fall. The hydraulic mechanism has a high carrying capacity and stability, can withstand large weight and pressure, and is suitable for the needs of various lifting devices. Secondly, the hydraulic mechanism has high precision and control performance, can achieve accurate height adjustment and position control, and make the lifting process more stable and reliable. In addition, the hydraulic mechanism runs smoothly, has low noise, a long service life, and relatively low maintenance costs. In addition, the hydraulic mechanism also has a self-locking function, which can stably maintain the lifting position even in the event of power failure or pressure failure, providing additional safety protection.

[0040] In order to protect the internal drive mechanism 2, the control panel 3 is provided with a first sleeve 31 on the side facing the drive mechanism 2, and the base 1 is provided with a second sleeve 11 facing the control panel 3. The first sleeve 31 is movably sleeved on the second sleeve 11. For details, please refer to Figure 3The first sleeve 31 and the second sleeve 11 together enclose a piston chamber 11a. The piston chamber 11a is a closed chamber that is not connected to the outside world. This prevents the drive mechanism 2 from being exposed to the air, thereby reducing the corrosion of the drive mechanism 2 and providing the drive mechanism 2 with dust and water resistance. In addition, the use of a sleeve mounted on the outside of the drive mechanism 2 also makes the overall device more beautiful and reduces safety hazards.

[0041] Since the first sleeve 31 and the second sleeve 11 will move relative to each other in actual use, there is a certain gap between them, so as to prevent the friction force generated by the first sleeve 31 and the second sleeve 11 from being too large and hindering the lifting and lowering of the driving mechanism 2. A rolling portion is provided between the first sleeve 31 and the second sleeve 11. For details, please refer to Figure 3 The rolling part not only does not hinder the movement of the driving mechanism 2, but also seals the piston cavity 11a, so that the interior of the piston cavity 11a is isolated from the external environment. It should be noted that the rolling part can be a flexible ring or a limiting roller 111, and the utility model does not limit this. In one embodiment of the utility model, the rolling part includes a plurality of limiting rollers 111 arranged along the outer circumference of the second sleeve 11. The limiting rollers 111 are evenly arranged to enclose and seal together. The limiting rollers 111 can also provide a smaller friction force, thereby reducing the obstruction to the movement of the driving mechanism 2.

[0042] It should be noted that the detection module 4 is a PIR human body detector 41. For details, please refer to Figure 1The PIR human detector 41 is a human detection technology based on PIR (Passive Infrared Sensor), which uses the change of infrared radiation to detect the presence of the human body. While the human body emits infrared radiation, it also absorbs infrared radiation in the surrounding environment. The PIR human detector 41 determines whether a human body passes by by detecting the change of infrared radiation in the environment. Specifically, the PIR human detector 41 is often composed of several infrared detectors, which are placed at specific angles and positions and can cover the area in front of the control panel 3. When a human body passes in front of the screen, the human body will cause the change of infrared radiation received by the detector. The PIR human detector 41 will send a signal by analyzing these changes. When the PIR human detector 41 detects the human body, the detection module 4 uses a human body identifier to identify the human body. It should be noted that the human body identifier can also be an infrared sensor or an ultrasonic sensor. The utility model does not limit this. In one embodiment of the utility model, the human body identifier is an infrared sensor. The PIR human detector 41 is a non-contact detection technology that does not require direct contact with the object to be detected, thereby avoiding cross infection and privacy issues. Secondly, the PIR technology is based on the detection principle of infrared radiation, and can work in a completely dark environment without being affected by light. In addition, the PIR technology is very sensitive to temperature changes, and can quickly and accurately detect the movement of the human body, with high sensitivity and accuracy. In addition, the cost of the PIR human detector 41 is relatively low, and the installation and debugging are relatively simple. When the PIR human detector 41 recognizes that a user is in front of the screen, it will convert the information into an electrical signal and transmit it to the control module 5. The control module 5 recognizes the height of the user through ultrasound, and then adjusts the height of the screen. A camera can also be used here to recognize the height of the human body to replace the control module 5.

[0043] To improve the practicability of the device, the adaptive lifting screen 1000 further includes an adjustment device 6. For details, please refer to Figure 1 The adjustment device 6 is arranged below the control panel 3 and is electrically connected to the driving mechanism 2. When the detection module 4 fails or is damaged, the user can adjust the control panel 3 by manually pressing buttons. The adjustment device 6 includes an up button and a down button. When the user continuously presses the corresponding button, the screen can be raised and lowered.

[0044] In one embodiment of the utility model, the adaptive lifting screen also includes an identity recognition module, which is used to identify the identity of the human body. If the identity recognition is correct, the identity recognition module controls the detection module 4 to initially recognize the human body. It should be further explained that the identity recognition module is a magnetic card recognition. The staff uses the magnetic card they carry to perform identity recognition. The identity recognition module reads the magnetic stripe information on the magnetic card and decodes it into recognizable data. The decoded data can be used for identity authentication, which is simple and convenient to operate and quickly completes the verification process.

[0045] The utility model also proposes a die-casting machine, which includes an adaptive lifting screen 1000. The specific structure of the adaptive lifting screen 1000 refers to the above-mentioned embodiment. Since the die-casting machine adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0046] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
