Description

Technical Field

[0001] The utility model relates to the technical field of glass powder compacting, in particular to a glass powder compacting machine. Background Technique

[0002] A glass powder compacting machine is a mechanical device used to compress glass powder into various shaped blanks. Its principle is that the glass powder in the hopper is fed into the die cavity. After the die is filled, the compacting machine applies pressure to the powder through a hydraulic cylinder or other pressure device. As the pressure increases, the voids between the glass powder particles are filled, the oxide films on the particle surfaces are broken, the contact area between the particles increases, and a green compact with a certain density and strength is formed. In this process, the powder rearranges and tightly combines under high pressure, gradually forming a solid glass product blank.

[0003] During the processing, the die needs to be preheated first to reduce the temperature gradient stress during the forming process. However, after the processing is completed, due to the unique material of the glass itself, a strong adhesion force is generated between the green compact and the die, resulting in difficulty in smoothly removing the green compact from the die. For the green compacts that do not need to be immediately processed subsequently, they can be allowed to cool naturally in the die to room temperature, but this reduces the production efficiency. They can also be directly taken out, but it is easy for the green compacts to deform during or after being taken out, affecting the shape and dimensional accuracy of the products. Therefore, we propose a new type of glass powder compacting machine to solve the above problems. Content of the Utility Model

[0020] By providing a glass powder embossing machine in the embodiments of the present application, the problem is solved that after processing, due to the unique material of the glass itself, a strong adhesion force is generated between the green compact and the mold, resulting in difficulty in smoothly removing the green compact from the mold. For green compacts that do not need to be immediately processed subsequently, they can be allowed to naturally cool to room temperature in the mold, but this reduces production efficiency. They can also be directly taken out, but it is easy for the green compact to deform during or after being taken out, affecting the shape and dimensional accuracy of the product.

[0021] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0022] The embodiments of the present utility model disclose a glass powder embossing machine.

[0023] According to the attached Figures 1-4 As shown, it includes an embossing machine body 1. A hydraulic cylinder 2 is fixedly installed inside the embossing machine body 1. A lower mold 3 is arranged below the hydraulic cylinder 2. A cooling and demolding mechanism 4 is arranged inside the embossing machine body 1. The cooling and demolding mechanism 4 includes a water-cooled pipe 401, a top plate 402, a push rod 403 and a guide rod 404;

[0024] When the device is in use, glass powder is put into the feed hopper and then into the interior of the lower mold 3 along the conduit. At the same time, the heating plate inside the lower mold 3 starts to heat up. The hydraulic rod at the bottom of the hydraulic cylinder 2 moves downward, and the guide rod 404 also moves downward accordingly, sliding the push plate 411 and the push rod 403 downward. The hydraulic rod is pushed into the interior of the lower mold 3 to complete the extrusion of the powder, forming a blank. The pressurized water tank 405 is started, and the cold water in the pressurized water tank 405 is transported through the cold water pipe 406 into the interior of the water-cooling pipe 401. The heat inside the lower mold 3 is evenly carried out by the water flow. After the blank cools down, the hydraulic rod is lifted upward, and the guide rod 404 also moves upward accordingly. The push plate 411 is lifted through the guide rod 404, so that the push rod 403 lifts the top plate 402, and the blank is pushed out of the lower mold 3, completing the work of pressing the glass powder into a blank.

[0025] The water-cooling pipe 401 is fixedly installed in the inner cavity sandwich of the lower mold 3. The top plate 402 is arranged inside the lower mold 3. The push rod 403 is slidably connected inside the press blanking machine body 1. The top of the push rod 403 abuts against the bottom of the top plate 402. The guide rods 404 are fixedly installed on both sides of the hydraulic cylinder 2, and the guide rods 404 are fixedly connected to the push rod 403. A heating plate is fixedly installed on the inner wall of the lower mold 3, and the heating plate is used to raise the temperature of the glass powder.

[0026] On one side inside the press blanking machine body 1, a pressurized water tank 405 is fixedly installed. The end of the pressurized water tank 405 is fixedly connected with a cold water pipe 406. On the side of the pressurized water tank 405 facing the central axis, a hot water pipe 407 is fixedly connected. The pressurized water tank 405 transports the cold water through the cold water pipe 406 into the interior of the water-cooling pipe 401 and discharges the heated water inside through the hot water pipe 407 from the interior of the water-cooling pipe 401 to achieve the purpose of cooling the lower mold 3.

[0028] On the outer surface of one end of the hot water pipe 407 close to the press blanking machine body 1, a heat dissipation member 408 is fixedly installed. On the end of the heat dissipation member 408 away from the press blanking machine body 1, a fan 409 is fixedly installed. Hot water enters the heat dissipation member 408 through the hot water pipe 407. A heat conduction plate is installed on the outer surface of the hot water pipe 407 inside the heat dissipation member 408 to transfer the heat inside the hot water pipe 407. There are heat dissipation holes at the end of the heat dissipation member 408 and the press blanking machine body 1. The fan 409 at the end of the heat dissipation member 408 blows the heat out of the press blanking machine body 1 through the wind, so that the temperature of the water inside the hot water pipe 407 is reduced, ensuring that the water inside the pressurized water tank 405 can play a cooling effect.

[0029] A top block 410 is fixedly installed at the bottom of the inner wall of the lower mold 3. The bottom of the top plate 402 abuts against the top of the top block 410. A push plate 411 is fixedly installed at the bottom of the push rod 403. The push plate 411 is fixedly connected to the guide rod 404. The top plate 402 is placed on the top of the top block 410. After processing, the push rod 403 pushes the top plate 402 together with the embryo on its top out of the lower mold 3 from bottom to top, completing the processing of the embryo.
