[0030] Please refer to Figure 1 、 Figure 2 and Figure 3This embodiment discloses a slider driving mechanism, including a slide rail 100, a slide seat 200 and a driving member 300. There are two slide rails 100, which are arranged side by side. A sliding space 101 is formed between the two slide rails 100. At least one of the two slide rails 100 is provided with a stroke detection sensor 400. For example, the two slide rails 100 are respectively a first slide rail 110 and a second slide rail 120. The stroke detection sensor 400 can be installed on the first slide rail 110 or the second slide rail 120, or there are multiple stroke detection sensors 400, and multiple stroke detection sensors 400 are respectively installed on the first slide rail 110 and the second slide rail 120. The slider base 200 is movably connected to the two slide rails 100. A detection portion 210 is provided on the slider base 200. The detection portion 210 is used to trigger the travel detection sensor 400. The travel detection sensor 400 can be a photoelectric switch, infrared sensor, or micro switch. The detection portion 210 is a structure adapted to the travel detection sensor 400. For example, when the travel detection sensor 400 is a non-contact sensor such as a photoelectric switch or infrared sensor, the detection portion 210 is a light-blocking structure. For another example, when the travel detection sensor 400 is a contact sensor such as a micro switch, the detection portion 210 is a triggering structure such as a shift block or lever. The output shaft of the driver 300 is connected to the slider base 200 and is used to drive the slider base 200 to move within the sliding space 101, thereby driving the slider through the slider base 200. The end of the slider away from the slider base 200 is provided with a molding portion for forming a mold cavity. Both slide rails 100 are connected to a connecting block 310, and the driver 300 is mounted on the connecting block 310. The driving member 300 can be a power member such as an oil cylinder, an air cylinder or a motor.

[0031] By arranging the stroke detection sensor 400 on the slide rail 100 and the detection unit 210 on the slider base 200, the movable rod can be eliminated. Even if the slider base 200 does not move due to an unreliable connection between the output shaft of the driver 300 and the slider base 200, the stroke detection sensor 400 can detect the movement of the detection unit 210, accurately detecting the movement of the slider and its stroke. The omission of the movable rod also avoids collisions between the movable rod and the mold plate, loosening of the detection unit 210 on the movable rod, and difficulty in disassembly for maintenance.

[0032] Please refer to Figure 2 and Figure 3The stroke detection sensor 400 includes a first detection sensor 410 and a second detection sensor 420. The first detection sensor 410 is used to detect a first detection point in the stroke, and the second detection sensor 420 is used to detect a second detection point in the stroke. For example, the first detection point indicates the point at which the slider base 200 is in the first working position, and the second detection point indicates the point at which the slider base 200 is in the second working position. Through the cooperation of the first detection sensor 410 and the second detection sensor 420, the position of the slider base 200 can be determined, thereby avoiding false detections caused by an unreliable connection between the output shaft of the driving member 300 and the slider base 200, and facilitating the reliable detection of the motion of the slider base 200.

[0033] For some application examples, see Figure 2 and Figure 3 The first detection sensor 410 and the second detection sensor 420 are both mounted on a linear rail 500, and the linear rail 500 is mounted on one of the two slide rails 100. For example, the linear rail 500 is mounted on the first slide rail 110 or the second slide rail 120, and the first detection sensor 410 and the second detection sensor 420 are both mounted on the linear rail 500. In other words, the first detection sensor 410 and the second detection sensor 420 are both mounted on the first slide rail 110. The linear rail 500 is a linear structure. For sensors of the same model, mounting the first detection sensor 410 and the second detection sensor 420 on the same linear structure can ensure that the detection ends of the first detection sensor 410 and the second detection sensor 420 are located on the same straight line, making it easier for the slider seat 200 to drive the detection unit 210 to trigger the first detection sensor 410 and the second detection sensor 420 during the linear motion. The first slider 510 and the second slider 520 are movably mounted on the linear rail 500, the first detection sensor 410 is mounted on the first slider 510, and the second detection sensor 420 is mounted on the second slider 520. The installation positions of the first detection sensor 410 and the second detection sensor 420 can be adjusted by the first slider 510 and the second slider 520 , so as to facilitate debugging during assembly or maintenance.

[0034] In other application examples (not shown), at least one of the two slide rails 100 is installed with a linear rail 500, and the stroke detection sensor 400 is installed on the linear rail 500. For example, the linear rail 500 is installed on the first slide rail 110, or the linear rail 500 is installed on the second slide rail 120, or the linear rail 500 is installed on both the first slide rail 110 and the second slide rail 120, and the stroke detection sensor 400 is installed on the linear rail 500. The stroke detection sensor 400 can be arranged in a variety of installation methods according to actual installation requirements. Among them, a slider is movably installed on the linear rail 500, and the stroke detection sensor 400 is installed on the slider. The installation position of the stroke detection sensor 400 can be adjusted by the slider, which facilitates assembly, commissioning, and maintenance.

[0035] Please refer to Figure 1 and Figure 3 The detection part 210 includes a connecting member 211 and a triggering member 212. The connecting member 211 is connected to the slider seat 200, and the triggering member 212 is connected to the connecting member 211 and can trigger the stroke detection sensor 400. The connecting member 211 can adopt a block-shaped, plate-shaped or rod-shaped structure. The connecting member 211 is used to play a connecting role between the triggering member 212 and the slider seat 200, so as to adapt to the installation height of the detection end of the stroke detection sensor 400. Among them, an adjustment hole 213 is provided on the triggering member 212, and is connected to the connecting member 211 by a fastener installed in the adjustment hole 213. In this way, the installation position of the triggering member 212 can be adjusted through the adjustment hole 213, which is convenient for adjustment during the assembly process and can be compatible with the dimensional errors of different parts during the processing process.

[0036] This embodiment also provides a mold including the above-mentioned slider drive mechanism. The specific structure of the slider drive mechanism can be found above and will not be described in detail here. By arranging the stroke detection sensor 400 on the slide rail 100 and the detection unit 210 on the slider seat 200, the movable rod can be eliminated. Even if the output shaft of the driving member 300 and the slider seat 200 are not connected reliably, and the slider seat 200 does not move, the stroke detection sensor 400 can detect the movement of the detection unit 210 based on the movement of the slider, and can accurately detect the movement and movement stroke of the slider.

[0037] This embodiment also provides a die-casting device including the aforementioned mold. The structure of the mold can be referred to above and will not be described in detail here. By arranging the stroke detection sensor 400 on the slide rail 100 and the detection unit 210 on the slider seat 200, the movable rod can be eliminated. Even if the output shaft of the driving member 300 and the slider seat 200 are not connected reliably, and the slider seat 200 does not move, the stroke detection sensor 400 can detect the movement of the detection unit 210 based on the movement of the slider, and can accurately detect the movement and movement stroke of the slider.

[0038] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
