Technical Field

[0001] This utility model belongs to the field of fixture and tooling technology, and specifically relates to a fixture for a lightweight substrate production line. Background Technology

[0002] Currently, in the production process of lightweight plant cultivation substrate, when molding by mold, clamps are needed to clamp and fix the mold to ensure the substrate molding quality and production stability. With the increase in production demand, the clamps not only need to meet the fixing function, but also need to be adapted to the automated production line to improve production efficiency.

[0003] Chinese patent CN209533156U discloses a lightweight matrix production line fixture, which consists of an upper mold fixture and a lower mold fixture. The upper mold fixture includes an upper mold fixture heating base plate, upper mold clamping plates located at the front and rear of the upper mold fixture, and upper mold fixture side plates located between the two upper mold clamping plates and on both sides of the upper mold fixture heating base plate. The lower mold fixture includes a lower mold fixture base plate and lower mold clamping plates located at the front and rear of the lower mold fixture. Its structure is simple, highly adaptable, and can fix molds of various sizes. It can also be used in conjunction with automated production lines, and has the characteristics of high efficiency and strong continuity.

[0004] However, the device has obvious defects and shortcomings in practical applications. On the one hand, although the overall installation structure is simple, the operation of disassembling and assembling the upper and lower molds is complicated. It lacks a quick mold opening structure, and the separation of the upper and lower molds requires manual operation, which cannot achieve quick adjustment and separation, thus affecting the production rhythm. On the other hand, when installing the upper and lower molds, it is difficult to quickly disassemble and replace molds of different sizes. For production scenarios that require frequent mold changes, this will significantly increase the operation time and labor intensity, reduce production efficiency, and fail to fully meet the needs of high-efficiency production. Therefore, it is necessary to improve its design. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a lightweight substrate production line fixture to solve the problems raised in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A lightweight substrate production line fixture includes a base, a mounting frame fixedly installed on the middle of one side of the base, an adjustment mechanism installed on the inner side of the mounting frame, and two movable ends of the adjustment mechanism fixedly installed with mounting mechanisms. The two movable ends of the adjustment mechanism are respectively mounted with an upper mold and a lower mold through the mounting mechanisms.

[0008] The adjustment mechanism includes a slide groove and a mounting groove. The slide groove is located inside the mounting frame, and a first lead screw is rotatably connected inside the slide groove. The mounting groove is located at the bottom of the mounting frame, and a drive motor is fixedly installed inside the mounting groove.

[0011] As a preferred technical solution, the mounting hole is set as a countersunk hole, and the outer corners of the base and the mounting bracket are both set as arcs.

[0012] As a preferred technical solution, the installation mechanism includes a connecting frame, which is fixedly installed on the side of the slider near the base. A rail frame is fixedly installed on the outer side of the connecting frame. The rail frame is fixedly installed on the outer side of the connecting frame. A second lead screw is rotatably connected inside the rail frame. The two ends of the second lead screw have opposite thread directions. Both ends of the second lead screw are threadedly connected to movable blocks. A clamping plate is fixedly installed on the inner side of the movable blocks.

[0024] Example

[0025] refer to Figures 1 to 5 A lightweight matrix production line fixture according to this embodiment includes a base 1, a mounting frame 2 fixedly installed on the middle of one side of the base 1, an adjustment mechanism 3 installed on the inner side of the mounting frame 2, and a mounting mechanism 6 fixedly installed on both moving ends of the adjustment mechanism 3. The upper mold 5 and the lower mold 4 are respectively installed on the two moving ends of the adjustment mechanism 3 through the mounting mechanism 6.

[0026] The adjusting mechanism 3 includes a slide groove 31 and a mounting groove 32. The slide groove 31 is located inside the mounting frame 2, and a first lead screw 33 is rotatably connected inside the slide groove 31. The mounting groove 32 is located at the bottom of the mounting frame 2, and a drive motor 34 is fixedly installed inside the mounting groove 32. The output end of the drive motor 34 passes through the bottom of the mounting frame 2 and is fixedly connected to the bottom of the first lead screw 33. The two ends of the first lead screw 33 have opposite thread directions, and both ends of the first lead screw 33 are threadedly connected to sliders 35. The mounting mechanism 6 is installed on the outside of the sliders 35. During the application of this device, in the fixture of its lightweight matrix production line, the working principle of the adjusting mechanism 3 is as follows: the drive motor 34 is fixedly installed in the mounting groove 32 at the bottom of the mounting frame 2, and its output end is fixedly connected to the bottom of the first lead screw 33 in the slide groove 31. When the drive motor 34 is started, the first lead screw 33 rotates synchronously with the output end. Because the threads at both ends of the first lead screw 33 rotate in opposite directions, the sliders 35 connected at both ends will move relative to or away from each other along the slide groove 31. This, in turn, drives the upper mold 5 and the lower mold 4 to move closer or further apart through the mounting mechanism 6 on the outside of the slider 35, thereby adjusting the mold spacing. Its advantages are that the drive motor 34 provides power to replace manual operation in adjusting the opening and closing of the upper mold 5 and the lower mold 4, resulting in a high degree of automation, precise control of the mold spacing, and suitability for the continuous operation requirements of automated production lines. At the same time, the threaded connection structure between the first lead screw 33 and the slider 35 ensures stable transmission and guarantees the smoothness of the mold adjustment process, avoiding the impact of shaking on the substrate pressing and molding quality. The guiding effect of the slide groove 31 on the slider 35 further improves the accuracy and reliability of the adjustment process, effectively solving the problems of mold separation relying on manual labor and low adjustment efficiency in the prior art.

[0027] refer to Figures 4-5The mounting mechanism 6 includes a connecting frame 61, which is fixedly mounted on the side of the slider 35 near the base 1. A rail frame 62 is fixedly mounted on the outside of the connecting frame 61. A second lead screw 63 is rotatably connected inside the rail frame 62. The two ends of the second lead screw 63 have opposite threads. Both ends of the second lead screw 63 are threadedly connected to movable blocks 64. A clamping plate 65 is fixedly mounted on the inner side of the movable blocks 64. The end of the second lead screw 63 away from the mounting frame 2 passes through the rail frame 62. The clamping plate 65 has an L-shaped cross-section. The upper mold 5 and the lower mold 4 are clamped inside the clamping plate 65 at the upper and lower ends, respectively. A limit plate 66 is fixedly installed on the outer end of the rail frame 62. An adjusting handle 67 is rotatably connected to the middle of the outer side of the limit plate 66. A locking screw 68 is threaded to one side of the adjusting handle 67. The outer side of the limit plate 66 has equally spaced ring-shaped locking holes 69. The end of the locking screw 68 passes through the adjusting handle 67 and is inserted into the inner side of the locking hole 69. The inner side of the adjusting handle 67 and the second The end of the lead screw 63 is fixedly connected. During the application of this device, during installation, the second lead screw 63 can be rotated within the rail frame 62 by rotating the adjusting handle 67. Because the threads at both ends of the second lead screw 63 turn in opposite directions, the movable blocks 64 at both ends drive the L-shaped clamping plates 65 to move relative to each other, clamping the upper mold 5 and the lower mold 4 inside the upper and lower clamping plates 65 respectively. Tighten the locking screw 68 so that its end is inserted into the locking hole 69 of the limiting plate 66, fixing the position of the second lead screw 63 to maintain the clamping state. The reverse thread drive enables the synchronous opening and closing of the clamping plate 65, which can quickly adapt to molds of different sizes. The L-shaped clamping plate 65 can stably limit the mold from both sides and the bottom to prevent displacement. The adjusting handle 67 cooperates with the limiting plate 66 and the locking screw 68 to complete the mold disassembly and assembly without tools, which is convenient to operate. The locking structure ensures that there is no loosening after clamping. The fixed connection between the connecting frame 61 and the rail frame 62 ensures the overall stability of the installation mechanism 6, which greatly improves the efficiency of mold replacement and solves the problem of cumbersome disassembly and assembly of traditional clamps.

[0028] refer to Figures 1-2The slider 35 has a convex shape when viewed from above, and the internal cavity of the slide groove 31 also has a convex shape. Wear-resistant pads are provided on the outer surface of the slider 35. Mounting holes 7 are provided at the four corners of the top of the base 1, with the bottom of each hole penetrating the base 1. The mounting holes 7 are countersunk holes. The outer corners of both the base 1 and the mounting bracket 2 are rounded. During application, the slider 35 has a convex shape when viewed from above, and the internal cavity of the slide groove 31 also has a convex shape. This fit ensures that the slider 35 will not deviate from the track when sliding along the slide groove 31, guaranteeing a stable sliding trajectory. The wear-resistant pads on the outer surface of the slider 35 reduce wear between the slider 35 and the slide groove 31. To reduce frictional wear and extend the service life of components, mounting holes 7 at the four corners of the top of the base 1 penetrate the base 1 and are used to insert bolts to fix the device in the designated position. The mounting holes 7 are countersunk holes so that the bolt heads do not protrude from the surface of the base 1, avoiding affecting the surrounding operation and overall flatness. The external edges of the base 1 and the mounting bracket 2 are rounded to prevent bumps and damage during operation and improve safety. These structures, through shape adaptation, material optimization and detailed design, ensure the stability of the slider 35 sliding, the regularity of the device installation and the safety of operation, and solve the problems of the slider 35 being easy to fall off, the rapid wear of components, and the installation protrusions and edges that can cause injury.

[0029] Operating principle and advantages: When this device is used, it is fixed to the designated position through the mounting holes 7 at the four corners of the top of the base 1. The countersunk hole design prevents the bolt head from protruding. The rounded edges of the base 1 and the mounting bracket 2 reduce collisions. When installing the upper mold 5 and the lower mold 4, rotating the adjusting handle 67 drives the second lead screw 63 to rotate. Because the threads at both ends of the second lead screw 63 turn in opposite directions, the movable blocks 64 at both ends will drive the clamping plates 65 to move relative to each other, clamping the upper mold 5 and the lower mold 4 in the L-shaped clamping plates 65 at the upper and lower ends respectively. Then, tighten the locking screw 68 so that its end is inserted into the locking hole 69 of the limiting plate 66 to fix the position of the second lead screw 63. When it is necessary to adjust the distance between the upper mold 5 and the lower mold 4, the drive motor 34 starts and drives the first lead screw 33 to rotate. Since the threads at both ends of the first lead screw 33 turn in opposite directions, the sliders 35 at both ends will slide along the convex groove 31. Through the mounting mechanism 6, the upper mold 5 and the lower mold 4 will move closer or further apart. The convex design of the slider 35, combined with the wear-resistant pad, can ensure stable sliding and reduce wear.

[0030] This device addresses the issue of manual operation and slow adjustment required for mold separation. It employs a drive motor 34 to rotate the first lead screw 33, causing the slider 35 to automatically open and close the upper mold 5 and lower mold 4, eliminating the need for manual separation and making it compatible with automated production lines. For the inconvenience of mold replacement, rotating the adjustment handle 67 allows the second lead screw 63 to drive the clamping plate 65 to open and close, quickly assembling and disassembling molds of different sizes. Other structural features include wear-resistant pads on the slider 35 to reduce sliding wear and extend service life; an L-shaped clamping plate 65 to stably hold the mold and prevent loosening; a limit plate 66 and a locking screw 68 to fix the adjusted second lead screw 63, ensuring secure clamping; and an arc-shaped... The sharp angles enhance operational safety, and the countersunk holes ensure a level installation. Thus, this device, through the drive motor 34 driving the first lead screw 33, achieves automatic adjustment of the upper mold 5 and lower mold 4, improving the level of production automation and meeting the needs of automated production lines. The design of the second lead screw 63 and clamping plate 65 in the installation mechanism 6 enables rapid disassembly and replacement of molds, reducing operation time and labor intensity, and improving production efficiency. Auxiliary structures such as wear-resistant pads and locking screws 68 ensure the stability and reliability of the device's operation, while the rounded angles and countersunk holes enhance safety and installation regularity, comprehensively solving the defects of existing technologies and adapting to the high-efficiency requirements of lightweight plant cultivation substrate production.
