Description

TECHNICAL FIELD

[0001] The present application relates to the field of stamping dies, in particular to a die sliding block assembly with self-positioning feedback. BACKGROUND

[0002] At present, die sliding blocks are widely used in industrial manufacturing, especially in precision manufacturing, automobile manufacturing and consumer electronics industries. The precise positioning and motion control of the sliding block play a crucial role in improving the quality and efficiency of die processing. In the prior art, the positioning detection of the sliding block is usually achieved by installing photoelectric detection modules or sensors. These photoelectric detection devices can monitor the position of the sliding block in real time, ensuring its positioning, thereby avoiding product defects caused by mispositioning or abnormal movement of the sliding block. However, such detection devices often require additional installation space, increasing the structural complexity and manufacturing cost of the die. In addition, the accuracy and reliability of the detection equipment will be affected by environmental factors and the accumulation of working time, resulting in errors in the position detection of the sliding block and affecting the normal operation of the die.

[0003] The installation of existing photoelectric detection modules or sensors not only increases the volume of the die, but also limits its application in small-sized dies. Especially in some space-limited application scenarios, the existing technology is difficult to meet the requirements of compact layout. At the same time, since photoelectric detection modules are usually expensive, the installation of such detection devices will undoubtedly increase production costs and affect the profit margin of manufacturing enterprises in cost-sensitive manufacturing fields. Furthermore, the maintenance of such detection devices is complex, and if a fault occurs during production, the repair and replacement process may cause downtime, thereby affecting production efficiency and delivery cycle. The existence of these problems makes it difficult for the existing die sliding block position detection technology to fully meet the needs of modern production under the conditions of high efficiency, reliability and low cost.

[0004] Based on the above shortcomings, a new type of die sliding block with self-positioning feedback is introduced, which has important research and development significance and application value. CONTENT OF THE INVENTION

[0005] The purpose of the present application is to overcome the shortcomings of the prior art and provide a die sliding block assembly with self-positioning feedback. The sliding block embeds a reflective photoelectric detection assembly on the sliding block body, which can realize self-positioning detection of the sliding block, avoid the need for installation of complex and expensive external photoelectric detection modules, save space and reduce manufacturing costs. At the same time, the implementation of self-positioning detection is more simple and efficient, and easy to maintain, which is conducive to the simplification of die operation management and the convenience of detection.

[0006] To achieve the above object, the application discloses a mold slider assembly with self-alignment feedback, which comprises a guide rail, a slider body mounted on the guide rail, a linear guide groove arranged on the slider body for cooperation with the guide rail, a mounting groove arranged on the bottom surface of the linear guide groove, and a reflective light interrupter mounted in the mounting groove through an adjustable support.

[0007] Further, the bottom plate is provided with a stop block for restraining the end point of the slider stroke.

[0008] Further, the reflective light interrupter comprises a transmitting end and a receiving end facing the bottom plate, and a light shielding partition plate is arranged between the transmitting end and the receiving end; the transmitting end is an infrared light emitting diode, and the receiving end is a photoelectric crystal.

[0009] Compared with the prior art, the application has at least one of the following beneficial effects:

[0010] 1. The mold detection system is simplified, and the cost is reduced: by embedding the reflective photoelectric detection assembly into the slider body, self-alignment detection of the slider is realized, and complex and expensive photoelectric detection modules are avoided, thereby saving space and reducing production cost.

[0011] 2. The accuracy and reliability of mold detection are improved: the design of the reflective light interrupter cooperating with the reflective block can accurately control the position of the slider and feedback in time, ensure the accurate alignment of the slider, effectively prevent misalignment and abnormal movement, and improve the stability of mold operation.

[0012] 3. The maintenance and management of the mold are simplified: since the self-alignment detection function is integrated into the slider, the dependence on external photoelectric modules is reduced, the equipment maintenance is more convenient, and since the structure is simple, the failure points are reduced, and the efficiency and reliability in the production process are improved.

[0023] Referring to the drawings Figures 1-4The embodiment provides a mold slider assembly with self-alignment feedback, aiming to solve the problems of complexity, high cost and difficult maintenance of the mold slider position detection system in the prior art. By integrating a reflective photoelectric detection component 3 in the slider body 2, the embodiment realizes a simple structure, low cost, easy maintenance and efficient mold slider position detection solution. This new design not only meets the requirements of modern production for precision and efficiency, but also effectively reduces the production and maintenance costs through the integrated structure. Compared with the traditional external photoelectric sensor detection system, the embodiment provides a more compact and efficient alternative solution with significant technical advantages and market application potential.

[0024] The slider assembly of the embodiment is composed of a slider body 2, a guide rail 1, a reflective light interrupter 3, a reflective block 4 and other related accessories. The slider body 2 is provided with a linear guide groove 201 matched with the guide rail 1, and the guide rail 1 is composed of a bottom plate 101 and a guide rail rod 102 installed in parallel on the bottom plate 101. The slider body 2 can freely slide on the guide rail rod 102, thereby realizing accurate positioning and control. In order to realize the self-alignment feedback function, the reflective light interrupter 3 is installed on the slider body 2 through an adjustable support 203, and can be aligned with the reflective block 4 installed on the guide rail bottom plate 101, thereby realizing the detection feedback of the slider alignment through the change of the optical signal.

[0025] The slider body 2 is designed with high-strength alloy steel material to ensure its stability and durability under high-speed and high-pressure working conditions. A linear guide groove 201 for matching with the guide rail 1 is arranged on the bottom surface of the slider, and a mounting groove 202 is formed in the bottom surface inside the guide groove 201 for mounting the reflective light interrupter 3. The light interrupter 3 is fixed in the mounting groove 202 through the adjustable support 203, and the design flexibility allows the installation position of the light interrupter 3 to be adjusted according to actual needs, thereby accurately controlling the trigger point of the detection signal. This design greatly simplifies the installation and adjustment process of the photoelectric sensor, making the implementation of the detection system more efficient and accurate.

[0026] The guide rail 1 is composed of a bottom plate 101 and two guide rail rods 102 installed in parallel on the bottom plate 101, and the guide rail rods 102 are precisely matched with the linear guide groove 201 of the slider body 2 to ensure that the slider body 2 can smoothly slide on the guide rail. In order to further enhance the detection accuracy of the system, a straight groove is arranged on the bottom plate 101 in the same direction as the guide rail rod 102, and a reflective block 4 is adjustably installed in the straight groove. The reflective block 4 is aligned with the emitting end 301 and receiving end 302 of the reflective light interrupter 3, and triggers the response of the light interrupter 3 signal through the change of the reflected light beam, thereby completing the feedback detection of the slider position. This design can accurately trigger the feedback signal when the slider is in place, ensuring the stable operation of the mold.

[0027] The working principle of the reflective light interrupter 3 is based on the reflection of infrared light. When the slider body 2 slides along the guide rail 1 and approaches the predetermined position, the photoelectric system begins to work. The reflective light block 4 installed on the slider body 2 is aligned with the reflective light interrupter 3 on the guide rail bottom plate 101. The infrared light-emitting diode (LED) as the transmitting end 301 emits a beam of infrared light, which is reflected by the reflective light block 4 and returns to the phototransistor as the receiving end 302. If the position of the reflective light block 4 is correct, the infrared light beam will return to the receiving end 302 along the predetermined path, activating the phototransistor and generating an electrical signal, based on which the system can determine whether the slider has reached the position. It is worth noting that the path of the reflected light is reflected by the reflective light block 4 and then returns to the receiving end 302 again. This process not only has high precision, but also greatly reduces the influence of external interference and improves the stability of the system.

[0028] To further improve the precision of the system, the position of the reflective light block 4 is adjustable, and an adjustable bracket 203 is designed to finely adjust the distance between the reflective light block 4 and the light interrupter 3. When the slider approaches the position, the adjustment of the reflective light block 4 will accurately control the intensity and return path of the reflected light, ensuring that the phototransistor at the receiving end 302 can accurately receive the reflected signal at the right time. By adjusting the position of the reflective light block 4, precise control of the detection trigger point can be achieved, achieving high-precision position feedback. This design makes the reflective light interrupter 3 flexible to adapt to different working conditions and production needs, further improving the adaptability and precision of the system.

[0029] To ensure that the light interrupter 3 can operate stably in complex working environments, the working distance and angle of the transmitting end 301 and the receiving end 302 can be adjusted according to actual needs. In addition, the design of the light shielding partition 303 effectively shields the interference of external light sources, ensuring that the system can maintain high-precision detection function in complex lighting environments. The function of the light shielding partition 303 is to avoid the direct influence of external light sources on the detection signal of the photoelectric sensor, improving the anti-interference ability and reliability of the system.

[0030] In addition to the above design, in order to improve the safety of the system, a stop block is provided on the bottom plate 101 to limit the travel end of the slider. The setting of the stop block can avoid the slider exceeding the predetermined working range during movement, thereby preventing equipment damage or safety hazards caused by overtravel. Through this design, the precise stop of the slider in each movement can be ensured, further improving the safety and stability of the system.

[0031] Compared to traditional external photoelectric sensor detection systems, this embodiment offers several significant advantages. Traditional external photoelectric sensors typically require the installation of an additional sensor module outside the mold, which not only increases the overall mold installation complexity but also takes up additional space, affecting the mold's compactness. Furthermore, external sensor modules typically require complex circuit wiring and precise adjustments to ensure proper operation. Over extended periods of operation, external sensors may be affected by external factors such as dust and vibration, resulting in reduced detection accuracy or system failure. These issues impact the long-term stability and reliability of traditional systems.

[0032] In contrast, this embodiment integrates the reflective photoelectric detection module within the slider body 2, eliminating the need for external equipment and reducing the complexity of installation and maintenance. The photoelectric detection module, through the reflective light interrupter 3 and the reflective block 4, provides self-aligned feedback directly within the slider body 2, reducing the possibility of external interference and significantly improving system stability. This integrated design makes the system more compact and stable, reducing production and maintenance costs while also improving detection accuracy and reliability. This design not only improves mold operating efficiency but also effectively reduces maintenance costs.

[0033] Based on the above, it can be understood that this embodiment optimizes the design of the slider assembly by integrating a self-aligning feedback function, overcoming many of the shortcomings of existing external photoelectric sensor detection systems. This provides the mold industry with an efficient, low-cost, and easy-to-maintain solution. Compared to traditional external photoelectric sensor detection systems, this embodiment offers higher integration, lower costs, stronger anti-interference capabilities, and higher detection accuracy. It possesses significant technical advantages and has broad application prospects.
