Description

Technical Field

[0001] This invention relates to the field of powder metallurgy mold technology, specifically to a high-temperature resistant powder metallurgy mold. Background Technology

[0002] Powder metallurgy molds are indispensable tools in the powder metallurgy process, mainly used for the forming and sintering of metal powders. The quality of the mold directly affects the quality of the finished product and production efficiency. Powder metallurgy generates heat during the pressing process, which can cause the blank temperature to reach 80-100 degrees Celsius. This results in a high temperature for the mold, making it prone to thermal expansion and contraction.

[0003] The high-temperature resistant powder metallurgy mold disclosed in CN 219924560 U can be opened by simply rotating the upper mold counterclockwise by one-eighth of a turn. The part of the mold that has cooled and formed inside the mold will break off due to the rotational torque, making the demolding process easier and effectively avoiding the problems of existing powder metallurgy molds, which are not only laborious but also difficult to open when demolding parts.

[0004] This high-temperature resistant powder metallurgy mold allows the upper mold to be rotated counterclockwise by one-eighth of a turn, breaking off the part that is stuck to the inner wall of the mold, making the demolding process easier. However, after the molded powder material is demolded, the staff needs to manually remove the material. Pressing the molded powder material can easily cause it to get stuck inside the mold, making it inconvenient for the staff to remove the molded material. Therefore, improvements are needed.

[0018] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0019] 1. This high-temperature resistant powder metallurgy mold, through a set pushing component, places powder into the inside of the feeding plate. The mold is constructed using a first cylinder, connecting plate, feeding plate, push plate, linkage plate, sliding plate, first rack plate, first pulley, first rotating rod, transmission belt, first fixed plate, second pulley, second rotating rod, second gear, and the first gear working in conjunction with the second fixed plate. When the feeding plate moves to the top of the lower mold, the powder inside the feeding plate falls into the lower mold, eliminating the need for manual powder loading, saving time and increasing work efficiency.

[0020] 2. This high-temperature resistant powder metallurgy mold, through the set ejection assembly, works in conjunction with the lower mold through the set fixed column, support frame, top plate, push plate, second rack, connecting frame, fixed strip, first spring, telescopic rod, slide rod, top plate and lower mold. The first spring drives the telescopic rod and push plate to move upward, so that the push plate moves upward through the slide rod and top plate, so that the top plate can eject the molded material, making it convenient for the staff to pick up the molded material.

[0021] 3. This high-temperature resistant powder metallurgy mold, through its set pressing mechanism, when it is necessary to press the powder material inside the lower mold, uses a set pressing plate, fixed frame, second cylinder, arc plate, linkage frame, extrusion plate, L-shaped plate, limit rack, limit gear, sliding plate, second spring and connecting rod to work together to make the pressing plate press the powder inside the lower mold into shape. After the powder is pressed into shape, the first spring drives the telescopic rod and the push plate to move upward, so that the push plate moves upward through the sliding rod and the top plate, so that the top plate can eject the shaped material, making it convenient for the staff to pick up the shaped material.

[0022] 4. This high-temperature resistant powder metallurgy mold, through its cooling mechanism, uses a combination of a water level pipe, water tank, base plate, condenser, return water pipe, protective cover, transmission pipe, water supply pipe, water pump, and cooling pipe. The condenser cools the water inside the return water pipe and then transmits it back to the water tank, making the water level inside the tank stable and preventing it from rising. This results in better cooling of the lower mold and improved high-temperature resistance of the lower mold. Attached Figure Description

[0050] Example 4

[0051] See Figure 1-10 Furthermore, based on Embodiment 1, the cooling mechanism 5 includes a protective cover 56, which is disposed around the lower mold 3293 and fixedly connected to the bottom of the processing table 2. A cooling pipe 501 is fixedly connected around the lower mold 3293. A water supply pipe 58 is fixedly connected to the front of the cooling pipe 501. A water tank 52 is fixedly connected to the back of the water supply pipe 58. A base plate 53 is fixedly connected to the bottom of the water tank 52.

[0052] Furthermore, the protective cover 56 has a circular hole inside that corresponds to the size of the water supply pipe 58 and the return water pipe 55, and the outer sides of the water supply pipe 58 and the return water pipe 55 are in close contact with the inner side of the protective cover 56. Through the circular hole, the water inside the water tank 52 can be transferred to the cooling pipe 501 through the water supply pipe 58 to cool the lower mold 3293.

[0053] In actual operation, when this device is used, the powder is placed inside the feeding plate 313. The first cylinder 311 drives the feeding plate 313 to move the push plate 314. The first cylinder 311 drives the slide plate 316 and the linkage plate 315 to move, so that the linkage plate 315 drives the first rack to rotate the first gear 3196. The first gear 3196 drives the first pulley 318 to rotate through the first rotating rod 319. The first pulley 318 drives the second pulley 3193 to rotate through the transmission belt 3191. The second pulley 3193 drives the second gear 3195 to rotate through the second rotating rod 3194.

[0054] The second gear 3195 drives the second rack 325 and the connecting frame 326 to move downward, the connecting frame 326 and the fixing bar 327 drive the push plate 324 to move downward, the push plate 324 can squeeze the telescopic rod 329 and the first spring 328, when the push plate 324 moves downward, it can drive the top plate 323 and the slide rod 3291 to move downward, the slide rod 3291 drives the top plate 3292 to move downward;

[0055] When the feeding plate 313 moves to the top of the lower mold 3293, the powder inside the feeding plate 313 can fall into the lower mold 3293, so that the operator does not need to manually put the powder into the lower mold 3293. The second cylinder 43 drives the pressing plate 41 and the arc plate 44 to move downward, so that the arc plate 44 can drive the linkage frame 45 to move downward, so that the linkage frame 45 can drive the extrusion plate 46 and the limiting rack 48 to move, so that the extrusion plate 46 can squeeze the second spring 402 through the sliding plate 401. When the limiting rack 48 meshes with the limiting gear 49, the second rotating rod 3194 is not easy to rotate.

[0056] The second cylinder 43 continues to drive the pressing plate 41 to move downward, so that the pressing plate 41 can press and shape the powder inside the lower mold 3293. After the powder is pressed and shaped, the second cylinder 43 drives the pressing plate 41 and the arc plate 44 to move upward, so that the linkage frame 45 moves away from the extrusion plate 46, so that the extrusion plate 46 drives the limiting rack 48 to move away from the limiting gear 49, so that the first spring 328 drives the telescopic rod 329 and the push plate 324 to move upward, so that the push plate 324 moves upward through the slide rod 3291 and the top plate 3292, so that the top plate 3292 can eject the shaped material. When the first cylinder 311 drives the feeding plate 313 to move, the feeding plate 313 drives the push plate 314 to move, so that the push plate 314 can push the ejected shaped material, making it easy for the staff to pick up the shaped material.

[0057] When the lower mold 3293 needs to be cooled, the water pump 59 transfers water from the water tank 52 to the cooling pipe 501 through the water pipe 58. The cooling pipe 501 cools the lower mold 3293. The cooled water is then transferred to the condenser 54 through the return water pipe 55. The condenser 54 cools the water in the return water pipe 55 and transfers it back to the water tank 52, making the water level in the water tank 52 stable and preventing it from rising. This improves the cooling effect of the lower mold 3293 and enhances its high-temperature resistance.
