Description

Technical Field

[0001] The utility model relates to the technical field of die equipment, in particular to a bead mechanism. Background Art

[0002] An injection mold is a mold widely used in current industrial production, especially a mold composed of a slider mechanism. For the structural design scheme of fixing the sliding direction of the slider, most adopt the T-groove type scheme of template digging or the bead fixing scheme with pins.

[0003] The patent publication number CN203665822U discloses a bead mechanism of an injection mold. By transversely providing convex strips at the lower ends on both sides of the slider, the bead is provided with a card slot adapted to and engaging with the convex strip at the corresponding position, and the slider seat is provided with a positioning slot adapted to and engaging with the card slot at the corresponding position. The convex strip of the slider is tightly fixed between the card slot and the slider seat in the longitudinal direction, and the slider is tightly fixed in the card slots of the beads on both left and right sides in the left and right directions. When the mold is closed and opened, the slider can smoothly, accurately and stably slide in and out in a single direction, so as to achieve an ideal mold closing and opening state, ensure the sliding accuracy of the slider, and make the slider not easy to be scratched or stuck.

[0004] However, during the use of the mold, the bead and the slider are in contact. As the slider slides, the bead and the corresponding module are relatively worn, resulting in a gap between the slider and the bead, thus affecting the subsequent stable sliding of the slider and the use of the mold. And because the bead structure is fixed, if you want to adjust the gap between the bead and the slider, you need to replace the bead, resulting in an increase in production costs. Summary of the Utility Model

[0005] In view of this, the purpose of the present utility model is to provide a bead mechanism to solve the problems that the bead is worn after long-term use, affecting the stable sliding of the slider, requiring the replacement of the bead, and affecting the production cost.

[0006] Based on the above purpose, the present utility model provides a bead mechanism, including a template, a slider receiving groove is opened on the template, a slider seat is installed in the slider receiving groove, bead grooves are opened on both sides of the slider seat, beads are installed in the bead grooves, a slider is arranged on the slider seat, the bead is in a 7-shaped form, a chute is formed between the horizontal section of the bead and the slider seat, both sides of the slider are slidably clamped in the chute, an adjusting plate is arranged on the inner side of the bead, and an adjusting mechanism for adjusting the position of the adjusting plate is arranged between the bead and the adjusting plate.

[0007] A further improvement lies in that the adjusting mechanism includes an adjusting bolt threadedly connected to the upper end of the pressing strip. An adjusting groove is formed in the pressing strip. The lower end of the adjusting bolt extends into the adjusting groove and is rotatably connected to an adjusting block. The adjusting block is slidably connected to the inner wall of the adjusting groove. Link rods are symmetrically hinged to both sides of the adjusting block. The lower ends of the link rods are both hinged to sliding sleeves. The sliding sleeves are slidably connected to the upper side of the adjusting plate.

[0008] A further improvement lies in that a sliding rod is provided on the adjusting plate. The sliding sleeve is slidably arranged on the sliding rod. A first spring is sleeved on the sliding rod. The two ends of the first spring are respectively connected to the sliding sleeves on both sides.

[0009] A further improvement lies in that guide blocks are fixedly connected to both ends of the upper side of the adjusting plate. Guide grooves are formed on both sides in the adjusting groove. The guide blocks are slidably arranged in the guide grooves.

[0010] A further improvement lies in that a second spring is connected between the lower side of the guide block and the inner wall of the guide groove.

[0011] A further improvement lies in that the size of the adjusting plate is the same as the size of the horizontal section of the pressing strip.

[0012] The beneficial effects of the present utility model are as follows: 1. By adopting the 7-shaped pressing strip, the slider is limited by the pressing strip and the slider seat, so that the slider can slide stably, improving the sliding accuracy, preventing jamming in the movement direction of the slider, and being simple in manufacture and assembly, capable of ensuring the appearance quality of the product, reducing the processing amount, and reducing the cost at the same time.

[0013] 2. By arranging an adjusting plate on the inner side of the pressing strip, the adjusting plate is adjusted through the adjusting mechanism, thereby adjusting the gap size between the pressing strip and the slider seat and reducing the maintenance cost after wear; through the action of the first spring and the second spring, the adjusting plate can closely fit on the surface of the slider, and at the same time, through the action of the spring, the adjusting plate can make a small movement, so that the adjusting plate can fit the slider without clamping the slider, ensuring the smooth sliding of the slider while reducing the gap between the adjusting plate and the slider.

[0023] Such as Figures 1-4As shown in the figure, a strip pressing mechanism includes a template 1. A slider receiving groove 2 is formed on the template 1. A slider seat 4 is installed in the slider receiving groove 2. Strip pressing grooves 3 are formed on both sides of the slider seat 4. A strip 6 is installed in the strip pressing grooves 3. The strip 6 is fixed to the slider seat 4 and the template 1 by screws. A slider 5 is arranged on the slider seat 4. The strip 6 is in the shape of a "7", and the strip 6 is composed of a horizontal section and a vertical section. A chute is formed between the horizontal section of the strip 6 and the slider seat 4. Both sides of the slider 5 are slidably clamped in the chute. An adjusting plate 7 is arranged inside the strip 6. An adjusting mechanism for adjusting the position of the adjusting plate 7 is arranged between the strip 6 and the adjusting plate 7. The adjusting plate 7 is arranged parallel to the lower side of the horizontal section of the strip 6. The size of the adjusting plate 7 is the same as that of the horizontal section of the strip 6. An adjusting mechanism is arranged between the strip 6 and the adjusting plate 7 to adjust the position of the adjusting plate 7 through the adjusting mechanism.

[0024] The adjusting mechanism includes an adjusting bolt 8 threadedly connected to the upper end of the strip 6. An adjusting groove 9 is formed in the strip 6. The lower end of the adjusting bolt 8 extends into the adjusting groove 9 and is rotatably connected to an adjusting block 10. The adjusting block 10 is slidably connected to the inner wall of the adjusting groove 9. Link rods 11 are symmetrically hinged to both sides of the adjusting block 10. Sliding sleeves 12 are hinged to the lower ends of the link rods 11. A sliding rod 13 is arranged on the adjusting plate 7. The sliding sleeves 12 are slidably arranged on the sliding rod 13. The sliding sleeves 12 are slidably connected to the upper side of the adjusting plate 7 through the sliding rod 13. By rotating the adjusting bolt 8, the adjusting block 10 is driven to move vertically downward. The link rods 11 rotate along with the vertical movement of the adjusting block 10 and push the sliding sleeves 12 to slide on the sliding rod 13. The adjusting plate 7 is pushed to move downward through the sliding of the sliding sleeves 12.

[0025] A first spring 14 is sleeved on the sliding rod 13. Both ends of the first spring 14 are respectively connected to the sliding sleeves 12 on both sides. The first spring 14 drives the sliding sleeves 12 on both sides to move towards each other. Guide blocks 15 are fixedly connected to both ends of the upper side of the adjusting plate 7. Guide grooves 16 are formed on both sides in the adjusting groove 9. The guide blocks 15 are slidably arranged in the guide grooves 16. A second spring 17 is connected between the lower side of the guide block 15 and the inner wall of the guide groove 16. The second spring 17 pulls the guide block 15 to move downward. Through the action of the first spring 14 and the second spring 17, the adjusting plate 7 moves downward to fit with the slider seat 4. At the same time, because the spring has elastic deformation, the adjusting plate 7 will not clamp the slider seat 4 while fitting with the slider seat 4, reducing the gap with the slider seat 4 while ensuring that the slider seat 4 can slide smoothly.

[0026] Principle of use: By rotating the adjusting bolt 8, the adjusting bolt 8 drives the adjusting block 10 to move downward. As the adjusting block 10 moves downward, the connecting rod 11 flips to both sides. The connecting rod 11 pushes the sliding sleeve 12 at the lower end to slide on the sliding rod 13, thereby pushing the adjusting plate 7 to move downward, making the adjusting plate 7 approach the slider 5. The second spring 17 drives the adjusting plate 7 to move downward through the guiding block 15 and fit on the slider 5, reducing the gap between the pressing strip 6 and the slider 5 and ensuring the smooth sliding of the slider 5.
