Description

Technical Field

[0001] The utility model relates to the technical field of a press machine for a thermally conductive interface material, in particular to a press machine for a thermally conductive interface material. Background Art

[0002] Thermal conductive materials are a new type of industrial material. These materials have been designed in recent years to meet the thermal conductivity requirements of equipment. They have excellent performance and are reliable. They are suitable for various environments and requirements, have proper countermeasures for possible thermal conductivity problems, and provide strong support for the high integration of equipment and ultra-small and ultra-thin. With the development of science and technology, thermal conductive materials are not limited to liquid materials, but also solid thermal conductive materials. When processing solid thermal conductive materials, they need to be extruded.

[0003] For example, the utility model with application number 202220790539.1 discloses a vacuum pressing machine for thermal conductive interface materials. A sealed space is formed in the fixed box through the sealing cooperation between the fixed box and the box door. The sealed space in the fixed box is evacuated by a vacuum pump using a connecting pipe to place the fixed box in a dust-free vacuum environment. When the hydraulic cylinder extends downward to drive the pressing plate to squeeze the material on the placement plate, the quality of the material after forming can be improved and dust contamination of the material can be reduced.

[0004] Similar to the above application, there are still some shortcomings:

[0005] This type of thermal interface material uses a vacuum press machine to create a dust-free vacuum environment using a fixed phase to improve the quality after molding. However, it is inconvenient to place the press barrel inside a fixed box, and the bottom support is fixed. Long-term extrusion will cause the bottom support force to deteriorate, and even cause the support block to be damaged and deformed, affecting the use of the press.

[0006] Therefore, a thermal conductive interface material pressing machine is designed to optimize the above problems. Utility Model Content

[0014] Preferably, a reinforcing plate is fixed on the top of each of the supporting blocks, and a triangular plate is fixed between the reinforcing plate and the supporting blocks.

[0015] The beneficial effects of the utility model are:

[0016] The utility model provides a press machine for thermally conductive interface materials. Through the coordinated use of a shell, a hydraulic cylinder, a press block, an operating table, a groove, an installation groove, an installation plate, a support block, a limit plate, a fixed cylinder, a spring, a universal wheel and a press cylinder, the press cylinder can be moved into the shell with relatively little effort, so as to achieve the purpose of efficiently completing the press work. Moreover, the support block at the bottom is easy to disassemble and maintain, which not only reduces the maintenance cost, but also improves the supporting force at the bottom and strengthens the stability of the press work. In addition, the arrangement of the limit plate and the spring can reduce the damage to the universal wheel during the press process and improve the protection effect of the universal wheel.

[0017] Through the coordinated use of the extension plate, the adjustment rod, the support seat and the limit rod, the adjustment rod is adjusted and rotated according to different use environments to make the support seat at the bottom move downward or upward so that the bottom of the support seat is more closely attached to the ground or the work surface, thereby meeting different installation requirements and also improving the stability and processing accuracy of the press for thermal interface materials;

[0018] Through the coordinated use of the limit tube, connecting rod, arc groove and ball, the pressing block moves up and down while driving the connecting rod and the limit tube to move up and down, and the ball inside the limit tube rolls while moving up and down, so that rolling friction is formed between the ball and the connecting rod, reducing the wear caused by friction, thereby improving the stability of the thermal interface material press and the protection effect of the limit rod.

[0024] In order to make the technical solution of the utility model more clear and specific to those skilled in the art, the utility model is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the utility model are not limited thereto.

[0025] Embodiment 1

[0026] like Figure 1-Figure 4As shown, the present embodiment provides a press for thermal interface materials, comprising a shell 1, a hydraulic cylinder 2 is installed on the inner top wall of the shell 1, a pressing block 3 is fixed to the telescopic end of the hydraulic cylinder 2, an operating table 4 is fixed to the inner bottom wall of the shell 1, a groove 5 is opened on the top of the operating table 4, and mounting grooves 6 are evenly opened on the inner bottom wall of the groove 5. Mounting plates 7 are slidably installed inside the mounting grooves 6, and a supporting block 8 is fixed on the top of the mounting plate 7. Limiting plates 9 are symmetrically arranged on the inner side walls of the groove 5. A pressing cylinder 13 is slidably connected inside the operating table 4, and fixed cylinders 10 are fixed on both sides of the pressing cylinder 13. Springs 11 are fixed on the inner top walls of the fixed cylinder 10, and universal wheels 12 are installed at the bottom of the springs 11, and the bottom of the universal wheels 12 is slidably connected to the top of the limiting plate 9. Extension plates 14 are fixedly installed on the front and rear sides of the shell 1, and adjusting rods 15 are threadedly connected at both ends of the extension plate 14. A support seat 16 is rotatably installed at the bottom of the adjusting rod 15.

[0027] The pressing cylinder 13 containing the material slides on the limit plate 9 and moves horizontally to the inside of the groove 5 through the universal wheel 12, and at the same time, the bottom of the pressing cylinder 13 is supported by the support block 8 and the mounting plate 7. Under the elastic force of the spring 11 and the limitation of the limit plate 9, the downward force when the hydraulic cylinder 2 drives the pressing block 3 to squeeze into the inside of the pressing cylinder 13 acts on the bottom of the pressing cylinder 13 and the support block 8, and will not cause damage to the universal wheel 12. When the support block 8 is damaged individually, the support block 8 can be directly removed from the groove 5, and the mounting plate 7 at the bottom can be removed from the mounting groove 6 for separate maintenance and replacement. According to different usage environments, the rotating adjustment rod 15 is adjusted to make the bottom support seat 16 move downward or upward so that the bottom of the support seat 16 is more in line with the ground or work surface.

[0028] Embodiment 2

[0029] In this embodiment, if Figure 1-Figure 4 As shown, a limit rod 17 is symmetrically installed on the top of the operating table 4, and a limit tube 18 is slidably installed on the outer side of the limit rod 17. A connecting rod 19 is fixed to one side of the limit tube 18, and one end of the connecting rod 19 is fixedly connected to the top of the pressing block 3. An arc groove 20 is opened inside the limit tube 18, and a ball 21 is rollingly installed inside the arc groove 20.

[0030] When the pressing block 3 moves up and down, it drives the connecting rod 19 and the limiting tube 18 to move up and down at the same time, and the ball 21 inside the limiting tube 18 rolls while moving up and down, so that rolling friction is formed between the ball 21 and the connecting rod 19, reducing the wear caused by friction.

[0031] In this embodiment, a reinforcement pad is fixed to the bottom of the support base 16 , and the reinforcement pad is a rubber reinforcement pad.

[0032] The provision of the reinforced rubber pad increases the friction force at the bottom of the support seat 16 and improves the overall stability.

[0033] In this embodiment, triangular grooves are formed on the outer sides of the mounting plates 7, and the mounting plates 7 are elastic blocks.

[0034] The triangular groove and the elastic mounting plate 7 make the mounting plate 7 more shock-absorbing and buffering, thereby reducing the wear of the mounting groove 6 caused by extrusion.

[0035] In this embodiment, a reinforcing plate is fixed on the top of each supporting block 8 , and a triangular plate is fixed between each supporting block 8 .

[0036] The provision of the reinforcing plate and the triangular plate increases the supporting area and the supporting force of the supporting block 8, thereby improving the supporting effect.

[0037] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto.
