Description

Technical Field

[0001] The invention relates to the technical field of powder metallurgy moulds, in particular to a water-cooled powder metallurgy mould. Background Art

[0002] Powder metallurgy forming is one of the basic processes in powder metallurgy production. The purpose is to pressurize loose (metal, ceramic or other material) powder into a semi-finished product with a predetermined geometry, size, density and strength in a mold, and then demold the semi-finished blank. Compression molding (steel mold) forming is the most widely used forming method in powder metallurgy production. Powder metallurgy has a unique chemical composition and mechanical and physical properties that cannot be obtained by traditional casting methods.

[0003] According to application number 202111174327.7, a water-cooled powder metallurgy forming mold specifically relates to the field of powder metallurgy mold technology, including a fixed frame, a lower mold and an upper mold. The outer end of the lower mold is provided with two symmetrical arc-shaped movable frames, and the inner end of the arc-shaped movable frame is fixed with a heat conduction plate. A cooling cavity is formed between the arc-shaped movable frame and the heat conduction plate, and the outer end of the fixed frame is provided with a water cooling mechanism.

[0004] The device avoids the shaking phenomenon during the pressing process, effectively improves the quality of the pressed product, and has a good use effect. The lower die is not fixedly connected to the fixed frame, which is convenient for replacing the lower die, improving work efficiency, and can keep the lower die in a constant low temperature state, greatly reducing the impact of thermal expansion and contraction on the lower die, facilitating demoulding of the lower die, making demoulding simpler and more convenient, and avoiding damage to the blank product during demoulding. It can be seen from the drawings in the specification of the device that after the device is pressed, the parts are removed from it by the staff, while the traditional mold is a continuous pressing mold, which will cause the staff to not have time to take the material, resulting in the risk of injury to the staff.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. The water-cooled powder metallurgy mold has a feeding mechanism. After the upper die seat and the lower die seat work well, the second hydraulic cylinder is started to move the molded parts upward, and then the third hydraulic cylinder is started to move the feeding cover to the right, thereby pushing the parts to the right. Then the motor is started to rotate the first shaft, thereby rotating the first gear. Since the first gear is meshed with the first rack and the first rack is fixed to the top of the inner wall of the box, the operation of the motor will cause the first connecting frame to move to the right. The rotation of the first shaft will cause the first pulley to rotate at the same time. The first pulley rotates the second pulley through the cooperation of the belt, thereby rotating the second shaft, and the second shaft drives the second gear to rotate. Since the second gear is meshed with the second rack, the second rack moves to the right, and the second rack drives the L plate to move to the right, thereby pushing the parts to move to the right and onto the guide plate. The parts slide on the guide plate to the L seat, and then the parts are taken away by the staff. The feeding process prevents the staff from directly taking the parts from the lower die seat with their hands, thereby preventing the staff from being injured.

[0017] 2. The water-cooled powder metallurgy mold has a feeding mechanism. When the first connecting frame moves to the right, it will drive the first rotating shaft to move to the right, thereby causing the first pulley to move to the right, further stretching the belt. The belt will drive the third pulley to move upward, and at the same time drive the guide rod to move upward. During this process, the spring will be squeezed, so the third pulley is squeezed by the elastic force of the spring, so that the belt is in a taut state, allowing the second pulley to rotate stably.

[0018] 3. The water-cooled powder metallurgy mold pours the metal powder into the lower material cover through the feeding port through the provided feeding mechanism, and then starts the third hydraulic cylinder to move the lower material cover to the right. During the process of the lower material cover moving to the right, the third gear will mesh with the third rack. Since the third gear meshes with the fourth gear, and the third gear is larger than the diameter of the fourth gear, the rotation of the third gear will cause the fourth gear to rotate rapidly, thereby rotating the brush roller. The process of the lower material cover moving to the right will also drive the brush roller to move to the right, thereby cleaning the dust on the top of the lower die seat with the brush roller to prevent the dust from affecting the die pressing of the parts. During the process of the lower material cover moving to the right, the lower material interface will overlap with the die groove, thereby causing the metal powder in the lower material cover to fall into the die groove. After that, the work of the spring third hydraulic cylinder causes the lower material cover to move to the left, and the brush roller will rotate in the opposite direction to continue cleaning the residual metal powder on the top of the lower die seat.

[0019] 4. The water-cooled powder metallurgy mold injects cooling water into the cooling box through the water inlet pipe through the cooling mechanism. After the injection is completed, the cooling pump is started. The cooling water in the cooling box is pumped into the lower die seat through the water outlet pipe and the first metal water pipe to cool the temperature of the lower die seat to prevent deformation and wear of the lower die and quality problems of the molded product caused by excessive temperature. The cooling water will flow into the cooling box through the second metal water pipe and be recycled. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Furthermore, a hole matching the water outlet pipe 55 is opened on the top of the cooling box 51 , and the surface of the water outlet pipe 55 passes through and is fixedly connected to the hole, and the bottom end of the water outlet pipe 55 is close to the bottom of the inner wall of the cooling box 51 .

[0035] Furthermore, the other end of the first metal water pipe 56 is fixedly connected to one end of the first water pipe connector 58 , and the other end of the second metal water pipe 57 is fixedly connected to one end of the second water pipe connector 59 .

[0036] In actual operation, when this device is used, after the upper die base 24 and the lower die base 28 are working well, the second hydraulic cylinder 27 is started to move the molded parts upward, and then the third hydraulic cylinder 42 is started to move the lower material cover 43 to the right, thereby pushing the parts to the right, and then the motor 318 is started to rotate the first rotating shaft 319, thereby rotating the first gear 3111. Since the first gear 3111 is engaged with the first rack 3112, and the first rack 3112 is fixed to the top of the inner wall of the box body 313, the operation of the motor 318 will cause the first connecting frame 317 to move to the right, and the rotation of the first rotating shaft 319 will cause the first pulley 321 to rotate, and the first The pulley 321 rotates the second pulley 324 through the cooperation of the belt 3214, thereby rotating the second shaft 323, and the second shaft 323 drives the second gear 3215 to rotate. Since the second gear 3215 is meshed with the second rack 3221, the second rack 3221 moves rightward, and the second rack 3221 drives the L plate 3219 to move rightward, thereby pushing the part to move rightward onto the guide plate 312, and the part slides onto the L seat 311 on the guide plate 312, and then the part is taken away by the staff. This unloading process prevents the staff from directly taking the part from the lower die seat 28 by hand, thereby preventing the staff from being injured; When the first connecting frame 317 moves to the right, it drives the first rotating shaft 319 to move to the right, so that the first pulley 321 moves to the right, further stretching the belt 3214, and the belt 3214 drives the third pulley 329 to move upward, and drives the guide rod 3212 to move upward, and in this process, the spring 3213 is squeezed, so that the third pulley 329 is squeezed by the elastic force of the spring 3213, so that the belt 3214 is in a tight state, so that the second pulley 324 can rotate stably; Pour the metal powder into the lower material cover 43 through the feed port 44, then start the third hydraulic cylinder 42 to move the lower material cover 43 to the right. During the movement of the lower material cover 43 to the right, the third gear 48 will mesh with the third rack 46. Since the third gear 48 is meshed with the fourth gear 411, and the third gear 48 is larger than the diameter of the fourth gear 411, the rotation of the third gear 48 will cause the fourth gear 411 to rotate rapidly, thereby rotating the brush roller 49, and the lower material cover 43 moves to the right. The process will also drive the brush roller 49 to move rightward, so that the brush roller 49 can clean the dust on the top of the lower die seat 28 to prevent the dust from affecting the die pressing of the parts. When the material cover 43 moves to the right, the material discharge interface will overlap with the die groove, so that the metal powder in the material cover 43 will fall into the die groove. Then, the spring 3213 and the third hydraulic cylinder 42 work to move the material cover 43 to the left, and the brush roller 49 will rotate in the opposite direction to continue to clean the residual metal powder on the top of the lower die seat 28. The cooling water is injected into the cooling box 51 through the water inlet pipe 53. After the injection is completed, the cooling pump 54 is started.
