Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for hot pressing sintering machines, specifically a material uniform spreading device for hot pressing sintering machines. Background Technology

[0002] A hot press sintering machine is a device used to sinter powdered or granular materials under high temperature and high pressure conditions. It is commonly used in ceramics, powder metallurgy, and other fields. The hot press sintering machine applies both high temperature and pressure to the material simultaneously, accelerating the atomic diffusion rate between particles and promoting particle bonding and densification. At high temperatures, the atoms in the material gain sufficient energy to overcome interfacial barriers and migrate; simultaneously, external pressure causes the particles to approach each other, deform, and fill pores, ultimately achieving the sintering and shaping of the material.

[0003] When processing materials using a hot press sintering machine, molds are needed to shape the materials. The shape and size of the molds determine the shape of the sintered products. However, when the materials are placed into the molds, it is not easy to spread the materials evenly, which can easily lead to uneven density of the sintered products. Utility Model Content

[0024] The power mechanism 4 includes a vertical rod 41, a mounting plate 42, a first motor 43, and an eccentric block 44. The vertical rod 41 is fixedly connected to the bottom of the worktable 2, and there are four sets of vertical rods 41. The mounting plate 42 is fixedly connected to the bottom of the vertical rod 41. The first motor 43 is located at the top of the mounting plate 42. The eccentric block 44 is fixedly connected to the output end of the first motor 43. When the eccentric block 44 rotates, it can squeeze the force block 7, which can make the placement table 5 shake.

[0025] The upper end of the workbench 2 has a through groove, and the placement platform 5 is placed in the groove. The workbench 2 is fixedly connected to the inner wall of the groove. When the placement platform 5 is not squeezed by external force, the top surface is horizontal with the top surface of the workbench 2.

[0026] The upper end of the workbench 2 is provided with a slide groove 21, and there are two sets of slide grooves 21. The first guide rod 22 is fixedly connected inside the slide groove 21.

[0027] The first slider 8 is slidably connected inside the slide groove 21. The first slider 8 is slidably connected to the first guide rod 22. The front of the first slider 8 has a hole that matches the first guide rod 22.

[0028] Two sets of first sliders 8 are rotatably connected by a positive and negative threaded rod 9. A second motor 10 is fixedly connected to the side of one set of first sliders 8 away from the positive and negative threaded rod 9. The output end of the second motor 10 is fixedly connected to the positive and negative threaded rod 9, and the positive and negative threaded rod 9 can be driven to rotate by the second motor 10.

[0029] A second guide rod 11 is fixedly connected between the two sets of first sliders 8. A second slider 12 is slidably connected to the side of the second guide rod 11, and there are two sets of second sliders 12. The second slider 12 is threadedly connected to the positive and negative threaded rods 9.

[0030] The second slider 12 is fixedly connected to a connecting rod 13 on the side near the hot pressing sintering machine body 1, and there are two sets of connecting rods 13. The end of the connecting rod 13 near the hot pressing sintering machine body 1 is fixedly connected to a clamping plate 14, and the concave surfaces of the two sets of clamping plates 14 are opposite each other.

[0034] In summary, the material uniform spreading device for a hot press sintering machine provided by this utility model allows the mold to be placed on the upper end of the placement table 5 during operation. Then, the material is placed into the mold. The first motor 43 drives the eccentric block 44 to rotate. The eccentric block 44 can squeeze the force block 7 once for one rotation. The frequent squeezing by the eccentric block 44 can cause the placement table 5 to vibrate. At this time, the placement table 5 can drive the mold to vibrate. The vibration of the mold can make the material inside the mold evenly spread in the mold.

[0035] The second motor 10 drives the positive and negative threaded rods 9 to rotate, which can bring the two sets of second sliders 12 closer to each other. At this time, the positions of the two sets of clamping plates 14 can be adjusted to move the two sets of clamping plates 14 to the left and right sides of the mold, while keeping the clamping plates 14 from contacting the mold. At this time, the clamping plates 14 can limit the mold, thereby preventing the mold from falling due to vibration. At the same time, the two sets of clamping plates 14 can clamp the mold. After clamping the mold, the telescopic cylinder 16 drives the connecting plate 17 to move closer to the hot pressing sintering machine body 1. At this time, the mold can be sent into the hot pressing sintering machine body 1. This structure makes it easy to send the mold into the hot pressing sintering machine body 1.
