Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a mold slider guide and tension adjustment device. Background Technology

[0002] In mold making, sliders are often used in conjunction with molds, and the guide rails, after high-frequency quenching, possess excellent wear resistance. Hardened guide rails have a large sliding contact surface, high rigidity, high stability, strong shock resistance, and high load-bearing capacity, making them suitable for heavy-duty cutting. However, due to the large contact area, the resistance is also high, leading to faster wear. The slow movement speed and susceptibility to creeping phenomena, along with gaps on the moving surfaces, can cause machining errors.

[0003] Chinese Utility Model Patent Publication No. CN221603771U discloses a guiding and tension adjustment device for a rigid rail slider. The specification of this device states that by adjusting the nut, the adjusting block is moved, thereby adjusting the gap between the slider and the rail. This achieves the beneficial effects of not only ensuring the linear movement of the slider and guiding it, but also reducing machining errors. However, this guiding and tension adjustment device for a rigid rail slider lacks a sliding guide structure, which easily leads to high friction when the two are in contact, making it difficult for the slider to move. With prolonged use, the high friction can easily cause damage. Summary of the Invention

[0004] The technical problem this invention aims to solve is to provide a mold slider guide and tension adjustment device. This device effectively addresses the issue in existing technologies where the lack of a sliding guide structure leads to high friction during contact, hindering displacement and causing damage over time due to excessive friction.

[0005] The technical solution adopted by this utility model is: a mold slider guide and tension adjustment device, including a base plate, a slide rail fixedly installed on the base plate, a slide block slidably connected to the end of the slide rail away from the base plate, a mold body provided at the end of the slide block away from the slide rail, and a guide component and a tension adjustment component fixedly installed at the end of the slide block close to the slide rail;

[0006] The guiding assembly includes a guide frame and a mounting frame. A limiting ring is fixedly installed at the end of the mounting frame away from the guide frame, and a guide ball is rotatably installed at the inner edge of the limiting ring.

[0007] The tension adjustment assembly includes a fixed frame and an adjustment frame. A tension roller is rotatably mounted on the end of the adjustment frame away from the fixed frame, and a screw is fixedly mounted on the end of the adjustment frame close to the fixed frame. The tension roller is in contact with the slide rail.

[0008] Preferably, the guide frame has a fixing groove at one end near the mounting frame, and the diameter of the fixing groove is the same as the diameter of the mounting frame.

[0009] With the above technical solution, the fixing slot of the guide frame has the same diameter as the mounting frame, which facilitates quick installation of both and allows the guide assembly to be securely installed on the slide block, preventing the guide ball from axially displacing when the mold slides, and ensuring the stability of the guide assembly.

[0010] Preferably, the guide ball passes through the mounting frame and extends to its upper and lower ends. The guide ball is in contact with the slide rail. The guide ball and the limiting ring are in one-to-one correspondence. Multiple guide balls and limiting rings are provided. The multiple guide balls and limiting rings are distributed at equal intervals.

[0011] Through the above technical solution, the guide balls and the limiting rings distributed at equal intervals form a multi-point support structure. The guide balls roll into contact with the slide rail, converting sliding friction into rolling friction, which can play a guiding role and prevent displacement during the movement.

[0012] Preferably, a sliding groove is provided at one end of the fixed frame near the adjusting frame, and sliding blocks are fixedly installed at the upper and lower ends of the adjusting frame, with the sliding groove and the sliding blocks being plugged in.

[0013] Through the above technical solution, the sliding block of the adjusting frame can be inserted into the slide groove of the fixed frame to facilitate the movement of the adjusting frame and adjust the distance between the tension roller and the slide rail.

[0014] Preferably, the sliding groove and the sliding block are provided in two identical sets, and each set of the sliding groove and the sliding block is provided in two identical sets, and the two sets of the sliding groove and the sliding block are symmetrically distributed about the center line of the fixed frame.

[0015] Through the above technical solution, the two sets of symmetrically distributed grooves and sliding blocks can facilitate the installation of the adjustment frame into the fixed frame, and can also play a guiding role in the later adjustment, and avoid the skewing caused by unilateral force. Moreover, the symmetrical structure makes the pressure of the tension roller on the slide rail evenly distributed, which can avoid unilateral wear of the slide rail and extend its service life.

[0016] Preferably, the screw and the fixed frame are threaded together, and a lever is fixedly installed at the end of the screw away from the adjusting frame.

[0017] With the above technical solution, the screw is threadedly connected to the fixed frame, and the pressure of the tension roller can be quickly adjusted by rotating the lever. No tools are required, and the adjustment can be made quickly to meet the mold sliding requirements under different working conditions.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1: As Figure 1-7 As shown, the present invention provides a mold slider guide and tension adjustment device, including a base plate 1, a slide rail 2 fixedly installed on the base plate 1, a slide block 3 slidably connected to the end of the slide rail 2 away from the base plate 1, a mold body 4 provided at the end of the slide block 3 away from the slide rail 2, and a guide component 5 and a tension adjustment component 6 fixedly installed at the end of the slide block 3 close to the slide rail 2.

[0031] The guide assembly 5 includes a guide frame 501 and a mounting frame 503. A limit ring 504 is fixedly installed at one end of the mounting frame 503 away from the guide frame 501. A guide ball 505 is rotatably installed at the inner edge of the limit ring 504.

[0032] The tension adjustment assembly 6 includes a fixed frame 601 and an adjusting frame 603. A tension roller 605 is rotatably mounted on the end of the adjusting frame 603 away from the fixed frame 601, and a screw 606 is fixedly mounted on the end of the adjusting frame 603 close to the fixed frame 601. The tension roller 605 is in contact with the slide rail 2.

[0033] Specifically, a fixing slot 502 is provided at one end of the guide frame 501 near the mounting frame 503. The diameter of the fixing slot 502 is the same as the diameter of the mounting frame 503. The advantage is that the fixing slot 502 of the guide frame 501 and the mounting frame 503 have the same diameter, which facilitates quick installation of both. It also facilitates the stable installation of the guide assembly 5 on the slide block 3, prevents the guide ball 505 from axially displacing when the mold slides, and ensures the stability of the guide assembly 5.

[0034] Specifically, a fixing slot 502 is provided at one end of the guide frame 501 near the mounting frame 503. The diameter of the fixing slot 502 is the same as the diameter of the mounting frame 503. The advantage is that, since the fixing slot 502 of the guide frame 501 is the same as the diameter of the mounting frame 503, the guide assembly 5 can be installed at the inner edge of the slide block 3, preventing the guide ball 505 from axially displacing when the mold slides, ensuring the stability of the guide assembly 5, and facilitating disassembly and assembly during later maintenance.

[0035] Specifically, the guide ball 505 passes through the mounting frame 503 and extends to its upper and lower ends. The guide ball 505 contacts the slide rail 2. The guide ball 505 corresponds one-to-one with the limiting ring 504. Multiple guide balls 505 and limiting rings 504 are provided. The multiple guide balls 505 and limiting rings 504 are distributed at equal intervals. The advantage is that the equally spaced guide balls 505 and limiting rings 504 form a multi-point support structure. The guide ball 505 rolls in contact with the slide rail 2, converting sliding friction into rolling friction, which can play a guiding role and prevent displacement during movement.

[0036] Example 2: Figure 2-7 As shown, this is an improvement on the previous embodiment.

[0037] Specifically, a groove 602 is provided at one end of the fixed frame 601 near the adjusting frame 603, and sliding blocks 604 are fixedly installed at the upper and lower ends of the adjusting frame 603. The groove 602 and the sliding blocks 604 are plugged in. The advantage is that the sliding blocks 604 of the adjusting frame 603 can be inserted into the groove 602 of the fixed frame 601, which facilitates the movement of the adjusting frame 603 and adjusts the distance between the tension roller 605 and the slide rail 2.

[0038] Specifically, there are two identical sets of slide grooves 602 and sliding blocks 604, with two identical slide grooves 602 and sliding blocks 604 in each set. The two slide grooves 602 and sliding blocks 604 are symmetrically distributed about the center line of the fixed frame 601. The advantage is that the two sets of symmetrically distributed slide grooves 602 and sliding blocks 604 can facilitate the installation of the adjustment frame 603 into the fixed frame 601, and can also play a guiding role in the later adjustment, and avoid the skewing caused by unilateral force. Moreover, the symmetrical structure makes the pressure of the tension roller 605 on the slide rail 2 evenly distributed, which can avoid unilateral wear of the slide rail 2 and extend its service life.

[0039] Specifically, the screw 606 is threadedly connected to the fixed frame 601. A lever 607 is fixedly installed at the end of the screw 606 away from the adjusting frame 603. The advantage is that the screw 606 is threadedly connected to the fixed frame 601, and the pressure of the tension roller 605 can be quickly adjusted by rotating the lever 607. No tools are needed, and the adjustment can be made quickly, which can adapt to the mold sliding requirements under different working conditions.

[0040] Working principle: During use, the fixing slot 502 of the guide frame 501 has the same diameter as the mounting frame 503, which facilitates quick installation of both and ensures that the guide assembly 5 is securely installed on the slide block 3. This prevents the guide balls 505 from axially displacing during mold sliding, ensuring the stability of the guide assembly 5. The tension roller 605 of the tension adjustment assembly 6 is in contact with the slide rail 2, and the adjusting frame 603 is moved up and down by rotating the screw 606, which adjusts the pressure of the tension roller 605 on the slide rail 2. The tension can be quickly adjusted according to the actual situation. The evenly spaced guide balls 505 and the limiting ring 504 form a multi-point support structure. The guide balls 505 roll in contact with the slide rail 2, converting sliding friction into rolling friction, which plays a guiding role and prevents them from moving too far. During the process, if displacement occurs, the sliding block 604 of the adjusting frame 603 can be inserted into the groove 602 of the fixed frame 601 to facilitate the movement of the adjusting frame 603. The distance between the tension roller 605 and the slide rail 2 can be adjusted. The two sets of symmetrically distributed grooves 602 and sliding blocks 604 can facilitate the installation of the adjusting frame 603 into the fixed frame 601 and also play a guiding role in subsequent adjustments. It also avoids the skewing caused by unilateral force. Moreover, the symmetrical structure makes the pressure of the tension roller 605 on the slide rail 2 evenly distributed, which can avoid unilateral wear of the slide rail 2 and extend its service life. The screw 606 is threadedly connected to the fixed frame 601. Rotating the lever 607 can quickly adjust the pressure of the tension roller 605 without the use of tools. It can be quickly adjusted and can be adapted to the mold sliding requirements under different working conditions.
