Description

Technical Field

[0001] This application relates to the field of molds, and particularly to a guiding slider for precision molds. Background Art

[0002] In the prior art, as an important component of molds, guiding sliders are widely used in the field of precision machining. The guiding slider ensures high precision and high stability of the mold during the machining process through precise sliding and positioning, thereby guaranteeing the machining quality of workpieces. However, there are still some deficiencies in the existing guiding sliders during actual use.

[0003] Firstly, the positioning accuracy of the existing guiding sliders often depends on the precision control of the mechanical structure itself. Usually, methods such as limit pins or mechanical brake blocks are used to position the initial and working positions of the slider. Although this method can meet the precision requirements to a certain extent, due to long-term use, the guiding slider and its limiting mechanism are prone to problems such as wear and loosening, resulting in a decrease in positioning accuracy. In addition, most of the existing guiding sliders in the prior art use direct contact of metal materials for sliding. Although some high-performance materials can extend the service life of the slider, wear caused by friction is still inevitable as the use time increases. These wear problems not only affect the sliding performance of the guiding slider but also may lead to a decrease in the machining precision of the mold, increasing the rejection rate of products.

[0004] Secondly, most of the existing guiding sliders in the prior art lack a real-time wear detection function and cannot timely remind the operator to replace or repair when the wear-resistant layer of the slider is worn through. Usually, the operator can only rely on regular manual inspections or handle the situation after obvious failures occur to the slider. This not only affects production efficiency but also may lead to a serious decline in the machining precision of the mold due to the failure to detect wear in a timely manner.

[0005] In view of the above deficiencies of the prior art, it is particularly important to develop a precision mold guiding slider with a wear detection function. Summary of the Utility Model

[0006] The purpose of this application is to at least overcome one deficiency existing in the prior art, and provide a guiding mold for precision molds, which can enable the slider to have a feedback function, effectively reduce machining errors caused by wear, improve production efficiency, and ensure the stability of product quality.

[0007] To achieve the above object, the present application discloses a guiding slider for a precision mold. The guiding slider includes a bottom plate with a guide rail, a body mounted on the bottom plate and cooperating with the guide rail, and a laser sensor embedded on the surface of the bottom plate and cooperating with the body. Among them, the slider has a guiding working inclined surface, and a wear-resistant plate is fixedly provided on the surface of the working inclined surface; the wear-resistant plate is a composite structure, including a wear-resistant layer, an insulating layer, and a bottom layer. Among them, a plurality of metal wires are arranged in parallel in the insulating layer, and the metal wires are insulated from each other. The metal wires are connected to a controller located inside the slider, and a plurality of conduction circuits are formed with the controller via the metal wires. After the metal wires are disconnected, the conductive circuit is disconnected, and the controller triggers a control signal; an installation induction plate is provided at the bottom of the guiding slider, and at least one hole groove for aligning and cooperating with the laser sensor is provided on the induction plate.

[0008] In some embodiments, a slot for installing the controller is provided on the side surface of the body. At the same time, a wire passing channel for connecting the metal wires of the insulating layer to the controller is also provided inside the body.

[0009] In some embodiments, a spring for resetting the body after movement is provided on the bottom plate.

[0010] Compared with the prior art, the present application has at least the following beneficial effects:

[0011] 1. Wear resistance detection and protection: By detecting the wear degree of the wear-resistant plate, it is possible to prevent the accuracy of the guiding slider from being affected due to excessive wear, effectively ensuring the guiding accuracy and processing quality of the mold.

[0012] 2. Prolong service life: The wear-resistant plate with a composite structure not only provides excellent wear resistance, but also can send out signals in time when the wear is excessive, prolonging the service life of the guiding slider and reducing the accuracy loss caused by wear.

[0013] 3. Improve operation reliability: Through the design of triggering the control signal by the fracture of the metal wire, it is ensured that it can be detected and processed in time when the wear is excessive, improving the reliability and operation safety of the entire system.

[0014] The beneficial effects listed above do not exhaust all advantages. Other potential beneficial effects and detailed technical implementation manners will be further disclosed in the embodiments or other description parts of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] As Figures 1 to 4 shown, in the embodiment, the overall structure of the guiding slider for precision molds includes components such as a body 1, a bottom plate 2, a working inclined surface 3, a wear-resistant plate 4, a laser sensor 5, a controller 6, and an induction plate 7. These components work through precise cooperation and coordination to achieve accurate detection of the position of the guiding slider and wear-resistant monitoring, thereby ensuring the processing accuracy and service life of the mold.

[0025] The bottom plate 2 is made of 42CrMo alloy steel, which has excellent mechanical strength and wear resistance. Its surface is quenched, and the hardness can reach HRC60 - 62, thus ensuring that the bottom plate 2 is not easily deformed during long-term use and has extremely high wear resistance. A guide rail is provided on the bottom plate 2. The guide rail is precision machined to ensure that the sliding contact surface between the guide rail and the body 1 is flat and smooth, and the straightness tolerance is controlled within ±0.01 mm. The body 1 can slide smoothly on the guide rail to ensure the precise positioning and stable operation of the slider. The bottom plate 2 also includes a mounting hole groove that cooperates with the laser sensor 5. The size of this hole groove is precisely designed, and its position is strictly geometrically calibrated to ensure that the laser sensor 5 can accurately detect the working position of the slider and perform fine-tuning calibration when necessary.

[0026] The body 1 is made of high-strength die steel, and SKD11 material is selected. It has excellent wear resistance and toughness and can effectively cope with the high-frequency sliding friction during die processing. The surface of the body 1 undergoes multiple heat treatments and polishing treatments, and the surface roughness is controlled below Ra0.2, further reducing the frictional resistance between the slider and the guide rail of the bottom plate 2 to ensure the smooth movement and stability of the slider. The bottom of the body 1 is directly slidably connected to the guide rail of the bottom plate 2 to ensure that the slider can still maintain precise sliding performance under long-term high-load use.

[0027] The working inclined plane 3 is a key part of the body 1 and is used to cooperate with the wear-resistant plate 4. The wear-resistant plate 4 is fixedly arranged on the working inclined plane 3, and its structure is a three-layer composite material. The first layer is a wear-resistant layer made of high-hardness metal, which has a low friction coefficient and can effectively reduce the friction loss when contacting other metal parts and provide excellent wear resistance. The middle layer is a polymer insulating layer with excellent insulating properties, which ensures the stable transmission of electrical signals and prevents short circuits or signal interference. The bottom layer is a structural layer made of metal material, which provides overall structural support for the wear-resistant plate 4 to ensure its stability and durability under high loads.

[0028] The detection principle of the wear-resistant plate 4 is as follows: When the slider is worn during operation, the first part to be worn is the wear-resistant metal layer. As the wear continues, the middle polymer insulating layer will gradually be exposed. When the wear further intensifies and reaches a certain degree, the metal structural layer at the bottom will start to be affected. At this time, the insulation of the middle layer is damaged, and the conduction loop connected to the controller 6 will be disconnected due to the wear of the insulating layer. The controller 6 can detect the interruption of the loop and immediately trigger an alarm signal to remind the operator to perform maintenance through the control system or automatically stop the machine to prevent the decline of processing accuracy caused by wear.

[0029] The induction plate 7 is an ordinary metal plate, whose function is to detect the position signal through the laser sensor 5. When the main body 1 slides along the guide rail of the base plate 2 and reaches the set position, the hole positions on the induction plate 7 will align with the laser sensor 5. The laser sensor 5 obtains an accurate position signal by detecting the hole positions on the induction plate 7 and feeds this signal back to the controller 6 to confirm that the slider has reached the set working position, thereby ensuring the position accuracy and operation stability during the entire processing process.

[0030] In actual use, this guiding slider can effectively cope with long-term high-frequency operations and ensure high precision and high stability during the processing through its wear-resistant detection and position monitoring functions. For example, in high-precision mold processing, since the product requires multiple repeated operations, this guiding slider can maintain an accurate initial position in each operation and issue a warning in a timely manner when the wear-resistant plate 4 wears to a critical level to prevent the decline in processing accuracy caused by wear. In addition, compared with traditional guiding sliders, the slider in this embodiment greatly improves its service life, reduces the maintenance frequency and production costs through the multi-layer structure design and real-time monitoring function of the wear-resistant plate 4.

[0031] In summary, through the precise design and reasonable configuration of each component, this guiding slider not only improves the service life but also effectively guarantees the processing accuracy, providing a reliable solution for precision mold processing. At the same time, in different usage scenarios, this slider can exhibit excellent performance. Especially in an environment with high load and high-frequency operations, it can still maintain a stable working state, further demonstrating the superiority of this technical solution.

[0032] Although the exemplary embodiments of the present disclosure have been described, those skilled in the art should understand that various changes and modifications can be made to the exemplary embodiments of the present disclosure without substantially departing from the spirit and scope of the present disclosure. Therefore, all changes and modifications are included within the protection scope of the present disclosure defined by the claims.
