Description

Technical Field

[0001] This utility model relates to the field of slide rail technology, specifically a mold lifting slide rail with dustproof function. Background Technology

[0002] Molds are usually made of metal, which makes them heavy and difficult to move. Moving molds often causes great trouble to production activities, which is not only time-consuming and labor-intensive, but also easily causes wear on the mold surface and poses a threat to the life safety of workers. Compared with roller type mold lifting slides, steel ball type mold lifting slides are more flexible and can achieve omnidirectional movement in the horizontal plane.

[0003] In practical applications, mold plates are usually heavy metal sheets. When placed on the mold lifting slide rail, they will generate a huge impact force on the slide rail, which can easily damage the slide rail and injure workers. In addition, the existing steel ball slide rails have a fixed length, which is difficult to meet the needs of mold plates of different specifications. Therefore, we propose a mold lifting slide rail with dustproof function. Utility Model Content

[0004] The purpose of this utility model is to provide a mold lifting slide rail with dustproof function.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dustproof mold lifting slide rail, comprising multiple slide rail sections, with two bases slidably connected inside each slide rail section. A universal ball is provided on the top side of the inside of each base. A pressing rod is connected to the center of the bottom end of each base. A spring is provided on the outer side of the pressing rod. A base plate is slidably connected to the bottom end of the pressing rod. A sliding rod is connected to the middle of the inside of each slide rail section. Two pressing blocks are slidably connected to the outer side of the sliding rod. A pressing block is provided on one side of each pressing block. The pressing block is slidably connected to the outer side of the sliding rod. Both pressing blocks are located below the pressing rod. A spring is provided in the middle of the outer side of the sliding rod. One end of the spring is connected to the outer wall of the left pressing block, and the other end is connected to the outer wall of the right pressing block. Both the left pressing block and the right pressing block are connected to the inner wall of the slide rail section via a spring.

[0006] As a further embodiment of this utility model: a plurality of positioning posts are connected to one side of the outer wall of the slide rail section, and a plurality of positioning grooves adapted to the positioning posts are opened on the other side of the outer wall of the slide rail section.

[0007] As a further embodiment of this utility model: a magnetic block one is provided at the middle of one side of the outer wall of the slide rail section, and a magnetic block two is provided at the middle of the other side of the outer wall of the slide rail section, wherein the magnetic block one and the magnetic block two are provided correspondingly.

[0008] As a further embodiment of this utility model: one end of the spring is connected to the bottom outer wall of the base, and the other end of the spring is connected to the top outer wall of the chassis.

[0009] As a further embodiment of this utility model: a dustproof plate is provided on the top of each of the multiple slide rail sections, and a limiting ring is connected to the left and right sides inside the dustproof plate. The limiting ring is located above the universal ball, and a retaining strip is provided on the bottom side of the dustproof plate.

[0010] As a further embodiment of this utility model: the bottom side of the dustproof plate is connected with a retaining strip, and the top of the slide rail section is provided with a retaining groove, the retaining groove and the retaining strip being configured accordingly.

[0011] As a further embodiment of this utility model: multiple positioning screw plates are connected to the sides of the two slide rail sections that are far apart from each other.

[0012] Compared with the prior art, the beneficial effects of this utility model by adopting the above technical solution are as follows:

[0013] 1. This utility model uses the cooperation of the universal ball and the base to support the mold plate when it is placed. During this process, the weight of the mold plate causes the universal ball and the base to move down, which in turn causes the extrusion rod to press down. At the same time, the first spring contracts and causes the first and second extrusion blocks to move to both sides, extruding the second and third springs, thereby reducing the instantaneous impact force on the slide rail body in multiple ways.

[0014] 2. This utility model, through the coordinated arrangement of multiple positioning columns and positioning grooves, enables two slide rail sections to quickly connect and be fixed by magnetic block one and magnetic block two, so that the two adjacent slide rail sections can be stably connected. This allows the length of the slide rail to be changed according to the usage requirements, making it convenient to use.

[0015] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

A base plate 7 is slidably connected to the bottom end of the extrusion rod 6. A slide rod 9 is connected to the middle of the inside of each slide rail section 1. Two extrusion blocks 10 are slidably connected to the outer side of the slide rod 9. An extrusion block 21 is provided on one side of each extrusion block 10. The extrusion block 21 is slidably connected to the outer side of the slide rod 9. Both extrusion blocks 10 and 21 are located below the extrusion rod 6. A spring 22 is provided in the middle of the outer side of the slide rod 9. One end of the spring 22 is connected to the outer wall of the left extrusion block 10, and the other end is connected to the outer wall of the right extrusion block 21. Both the left extrusion block 21 and the right extrusion block 10 are connected to the inner wall of the slide rail section 1 via a spring 313.

[0023] In Embodiment 1, a plurality of positioning posts 14 are connected to one side of the outer wall of the slide rail section 1, and a plurality of positioning grooves 17 adapted to the positioning posts 14 are opened on the other side of the outer wall of the slide rail section 1. A magnetic block 15 is provided in the middle of one side of the outer wall of the slide rail section 1, and a magnetic block 26 is provided in the middle of the other side of the outer wall of the slide rail section 1. The magnetic block 15 and the magnetic block 26 are provided in a corresponding manner.

[0024] Specifically, by inserting multiple positioning pins 14 into the corresponding positioning slots 17, the two slide rail segments 1 can quickly connect when they are connected, and are attracted and fixed by magnetic block 15 and magnetic block 2 16, so that the two adjacent slide rail segments 1 can be stably connected.

[0025] In embodiment 2, one end of spring 8 is connected to the bottom outer wall of base 5, and the other end of spring 8 is connected to the top outer wall of chassis 7. Dustproof plates 2 are provided on the top of multiple slide rail sections 1. Limiting rings 3 are connected to the left and right sides inside the dustproof plate 2. The limiting rings 3 are located above the universal ball 4. A retaining strip 18 is provided on the bottom side of the dustproof plate 2. The retaining strip 18 is connected to the bottom side of the dustproof plate 2. A retaining groove is opened on the top of the slide rail section 1. The retaining groove and the retaining strip 18 are correspondingly set. Multiple positioning screw plates 19 are connected to the side of the left and right slide rail sections 1 that are far apart from each other.

[0026] Specifically, the weight of the mold plate drives the universal ball 4 and the base 5 to move down, causing the extrusion rod 6 connected to it to press down. At the same time, the spring 8 contracts, causing the extrusion block 10 and the extrusion block 2 11 to move to both sides, extruding the spring 2 12 and the spring 3 13. This reduces the instantaneous impact force on the slide rail body in multiple ways. The dustproof plate 2 is connected to the slide rail section 1 by the setting of the locking strip 18.

[0027] Working principle:

[0028] In use, the head slide section 1 is fixed in the designated position by the positioning screw plate 19. Then, according to the usage requirements, the slide section 1 is spliced ​​by inserting multiple positioning pins 14 into the corresponding positioning slots 17, so that the two slide sections 1 can be quickly connected. They are then attracted and fixed by magnetic block 15 and magnetic block 2 16, so that the two adjacent slide sections 1 can be stably connected. After completion, the mold plate is placed. Through the cooperation of the universal ball 4 and the base 5, the mold plate is supported by the universal ball 4 when it is placed. During this process, due to the weight of the mold plate, the universal ball 4 and the base 5 move down, causing the extrusion rod 6 connected to it to press down. At the same time, the spring 1 8 contracts, and the extrusion blocks 10 and 2 11 move to both sides to compress the spring 2 12 and spring 3 13, thereby reducing the instantaneous impact force on the slide body. The dustproof plate 2 is connected to the slide section 1 by the setting of the clip 18 to avoid affecting the use of the slide body. At this point, the entire process is completed.
