Description

Technical Field

[0001] The present application relates to the field of molds, and in particular to a slider assembly with a position detection function. Background Art

[0002] In the field of mold manufacturing, slider assemblies are widely used in the molding process of various complex parts. Traditional slider assemblies mainly rely on mechanical structures to achieve relative movement between the insert and the slider, so as to ensure that the mold can successfully complete the required processing operations during the production process. This structure usually includes one or more sliders, and the position of the insert is controlled by the movement of the slider to achieve precise processing of the mold. However, a major problem with current slider assemblies is that the relative position and matching relationship between the insert and the slider are undetectable during the working process. Due to the lack of real-time detection and feedback, this part of the mold status cannot be effectively monitored and managed during the production process.

[0003] This problem is particularly prominent in production environments that require high precision and high quality. With the improvement of the manufacturing industry's technological level, the requirements for mold processing accuracy are also increasing, and traditional slider components cannot meet this demand. The relative position relationship between the insert and the slider directly affects the accuracy and quality of mold processing, but since this key parameter cannot be detected, it may cause position offset, poor fit and other problems during the production process, thereby affecting the quality of the final product. This uncontrollability not only reduces production efficiency, but also increases scrap rate and production costs.

[0004] The main reason for these shortcomings lies in the limitations of the traditional slider assembly design. In the traditional design, the relative movement of the slider and the insert is completely dependent on mechanical drive, without the introduction of any detection and feedback mechanism. This design can meet basic needs when the early production requirements are low, but with the advancement of technology and the intensification of market competition, the requirements for precision and consistency in mold manufacturing are getting higher and higher, and the limitations of the traditional slider assembly are gradually emerging. In addition, the lack of position detection function also makes mold maintenance and troubleshooting more difficult. Potential problems in production are often difficult to detect in the early stages, making subsequent repair work more complicated and time-consuming.

[0005] In order to solve the above problems and meet the needs of modern manufacturing industry for high precision and high efficiency, it is of great significance to develop a slider assembly with position detection function. Utility Model Content

[0006] The purpose of the present application is to overcome at least one of the shortcomings of the prior art and to provide a slider assembly with a position detection function. The slider assembly introduces a position detection function that can not only monitor the relative position of the slider and the insert in real time to ensure that they are always in the best matching state, but also can adjust or correct the deviation in time after the position error, thereby improving the accuracy and stability of mold processing.

[0007] To achieve the above-mentioned purpose, the present application discloses a slider assembly with a position detection function, the assembly includes a plunger and a slider opposite to the plunger, wherein the plunger has a working inclined surface, and oppositely, the slider is provided with a guide inclined surface matching the working inclined surface; an upper slot is concavely provided on the working inclined surface, and a photoelectric sensor is provided in the upper slot; two mutually insulated elastic contacts are also provided on the working inclined surface, the elastic contacts are higher than the working inclined surface and can be elastically retracted to be flush with the working inclined surface, when the working inclined surface contacts the guide inclined surface, the two elastic contacts are electrically connected via the slider, thereby triggering a sensing signal; a lower slot is provided on the guide inclined surface of the slider, opposite to the upper slot; a triangular block with a sensing hole is installed on the lower slot, the sensing hole of the triangular block is opposite to the photoelectric sensor, and the optical fiber sensor generates a sensing signal when passing through the sensing hole.

[0008] In some embodiments, both the working inclined surface and the guide inclined surface are provided with a wear-resistant coating.

[0009] In some embodiments, the triangular block is detachably mounted in the lower slot.

[0010] In some embodiments, a guide protrusion that cooperates with the guide rail is protruded from the bottom of the sliding block.

[0011] In some embodiments, at least two sensing holes are provided, one of which is located vertically directly below the photoelectric sensor when the insert knife and the slider are matched, and the other is located vertically directly below the photoelectric sensor when the insert knife and the slider are in the matched stop position.

[0012] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0013] 1. Realize accurate position detection: By setting photoelectric sensors and elastic contacts on the working inclined surface of the insert, combined with the relative sensing holes and guide inclined surfaces on the slider, accurate position detection of the slider assembly during the working process can be achieved, ensuring that the relative position of the insert and the slider is always in the best matching state, thereby improving the accuracy and consistency of mold processing.

[0026] Implementation column:

[0027] like Figures 1 to 4 As shown, in this embodiment, the slider assembly with position detection function includes a plunger 1, a slider 2, a working inclined plane 3, a guide inclined plane 4, an upper slot 5, a photoelectric sensor 6, an elastic contact 7, a lower slot 8, a triangular block 9, a sensing hole 10, a guide protrusion 11 and other components. Each component works in synergy through reasonable structural design and precise coordination to ensure that the slider assembly can accurately detect and control the relative position of the plunger 1 and the slider 2 during the mold processing process.

[0028] Specifically, the relative movement between the plunger 1 and the slider 2 is achieved through the working inclined surface 3 and the guiding inclined surface 4. The working inclined surface 3 of the plunger 1 is designed as an inclined surface, corresponding to the guiding inclined surface 4 of the slider 2, and the two achieve precise sliding control through contact and cooperation. When the plunger 1 pushes the slider 2 to move along the working inclined surface 3, the guiding inclined surface 4 plays a guiding role to ensure that the slider 2 can move smoothly along the predetermined path.

[0029] An upper slot 5 is designed on the working inclined surface 3 of the insert blade 1 , and a photoelectric sensor 6 is fixedly installed in the upper slot 5 for detecting the moving state of the slider 2 and its relative position.

[0030] In order to achieve real-time detection of the matching state of the insert blade 1 and the slider 2, two mutually insulated elastic contacts 7 are also provided on the working bevel 3. The elastic contacts 7 are slightly higher than the surface of the working bevel 3, and can be compressed and retracted to be flush with the working bevel 3 when the slider 2 moves into position. The main function of the elastic contacts 7 is to serve as a preliminary detection device. When the insert blade 1 and the slider 2 are in contact and matched, the conductive slider turns on the elastic contacts 7 to trigger, thereby sending a signal, indicating that the insert blade 1 and the slider 2 have achieved preliminary precise matching. This signal will trigger the start of the photoelectric sensor 6 to start further precise position detection.

[0031] Next, when the slider 2 continues to move and reaches a specific position, the photoelectric sensor 6 determines its specific position by detecting the sensing hole 10 on the slider 2. On the guide slope 4 of the slider 2, a lower slot 8 is provided at a position corresponding to the upper slot 5, and a triangular block 9 is installed in the lower slot 8. At least two sensing holes 10 are designed on the triangular block 9. The positions of the sensing holes 10 are precisely calculated and designed, one of the sensing holes 10 is located vertically directly below the photoelectric sensor 6 when the insert 1 and the slider 2 are fully matched, and the other sensing hole 10 is located directly below the photoelectric sensor 6 when the slider 2 moves to the matching stop position.

[0032] It should be understood that the working principle of the photoelectric sensor 6 is based on the photoelectric effect. When the slider 2 moves to a specific position, the photoelectric sensor 6 will determine whether the slider 2 has reached the preset detection point by detecting the light signal transmitted through the sensing hole 10. After receiving the signal, the photoelectric sensor 6 will convert the light signal into an electrical signal and transmit it to the control system. The control system makes a judgment based on these signals. If the slider 2 does not reach the predetermined position, the system will adjust the movement of the slider 2 in time according to the feedback signal to ensure the accuracy and consistency of the processing process. Through this design, the slider assembly can monitor the relative position between the insert 1 and the slider 2 in real time, which greatly improves the accuracy of mold processing.

[0033] In addition, in order to improve the durability of the slider assembly, the working bevel 3 of the insert 1 and the guide bevel 4 of the slider 2 are both provided with a wear-resistant coating. The wear-resistant coating is made of high-strength wear-resistant materials, such as silicon carbide or boron nitride coating, which can effectively reduce friction and reduce the risk of wear, thereby extending the service life of the slider assembly and ensuring that it can still maintain a high-precision working state under long-term and high-frequency use.

[0034] In addition, a guide protrusion 11 is designed at the bottom of the slider 2, and the guide protrusion 11 cooperates with the guide rail in the mold to ensure that the slider 2 remains stable during movement without lateral deviation or shaking. The design of the guide protrusion 11 not only improves the movement accuracy of the slider 2, but also further ensures the detection accuracy of the photoelectric sensor 6.

[0035] In actual operation, when the slider assembly is used in mold manufacturing, for example, in the processing of high-precision automotive parts, the insert knife 1 moves along the guide slope 4 by pushing the slider 2. In this process, the elastic contact 7 first detects the initial matching state between the insert knife 1 and the slider 2. When the elastic contact 7 is compressed and retracted and triggers a signal, the photoelectric sensor 6 immediately starts to work and confirms whether the slider 2 has reached the predetermined position by detecting the light signal of the sensing hole 10. If the photoelectric sensor 6 confirms that the slider 2 has reached the correct position, the mold system will continue the processing operation; if a position deviation is detected, the system will automatically adjust the position of the slider 2 to correct the deviation.

[0036] The design of the slider assembly not only improves the precision and stability of mold processing, but also reduces the error of manual operation and improves production efficiency. During maintenance and use, the triangular block 9 adopts a detachable installation design, which makes it more convenient to maintain or replace the assembly, reduces downtime, and further improves the operating efficiency of the production line.

[0037] In summary, this slider assembly with position detection function realizes real-time monitoring and adjustment of the relative position of the slider 2 and the insert 1 during mold processing through precise structural design and material selection, combined with preliminary detection of the elastic contact 7 and precise position detection of the photoelectric sensor 6, which significantly improves the production accuracy, efficiency and safety. It is widely applicable to various high-precision manufacturing scenarios and has important application value and market potential.
