Description

Technical Field

[0001] The present invention belongs to the technical field of hardware casting and forming equipment, and specifically relates to a metal hardware casting and forming equipment. Background Art

[0002] As one of the important processes for manufacturing hardware, casting and forming technology occupies an important position in the production of metal products. The metal hardware casting and forming device, as the core equipment of casting and forming technology, is a device that injects molten metal into a mold and forms the required shape and size of the metal material in the mold through the processes of solidification and cooling.

[0003] A patent with the publication number CN118237568B discloses a metal hardware casting and forming device. The provided cooling and conveying mechanism includes a processing box, a cooling component, and a pushing component. The pushing component is connected to the lifting component and the processing box, realizing automatic cooling of the hardware during the casting process, thereby improving work efficiency.

[0004] In the above-mentioned prior art, when processing hardware, it is necessary to inject molten metal into the mold and wait for the molten metal to cool and solidify before performing extrusion forming. Since the temperature of the molten metal is relatively high, it is necessary to cool the mold in time after processing one workpiece. A higher mold temperature will cause a longer cooling time for the internal molten metal. The existing cooling methods use air cooling or water cooling for cooling, which can only cool the surface of the mold and has a short contact time with the mold surface, resulting in a longer waiting time for the mold to cool, affecting the subsequent casting efficiency of the hardware and having a low work efficiency.

[0034] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0035] Example 1

[0036] As Figures 1 - 7As shown in the figure, a metal hardware casting and forming device according to an embodiment of the present invention includes a disc 1. The middle part of the lower end of the disc 1 can rotate on the upper end of a bottom plate 6 through a support column 11. One side of the upper end of the bottom plate 6 is fixedly connected with a column 3. A fourth ring 33 is slidably arranged on one side of the column 3. A plurality of molds 12 are respectively fixedly connected to the edge of the disc 1. A first ring 121 is slidably arranged in the middle of the mold 12. A cylindrical block 122 is arranged in the middle of the first ring 121. A cross block 1221 is fixedly connected to the lower end of the cylindrical block 122. The four corners of the cross block 1221 are fixedly connected to the disc 1 through first rectangular blocks 1222. The middle parts of the cross block 1221 and the cylindrical block 122 are both hollow structures and are interconnected. The middle part of the mold 12 is a hollow structure. First circular tubes 123 are respectively fixedly connected to one side of the mold 12 and the cross block 1221. A water changing assembly is arranged on one side of the upper end of the bottom plate 6. The water changing assembly includes two second circular tubes 55 slidably arranged on the upper end of the bottom plate 6. Third circular tubes 551 are respectively fixedly connected to the ends of the second circular tubes 55 away from the disc 1.

[0037] Specifically, when processing hardware parts, the casting molding method is generally used for processing. When casting hardware parts in the prior art, the circular ring mold is prepared first, and then the metal melt is injected into the circular ring mold. After waiting for the metal melt to cool and solidify, the hardware part is taken out, so that the metal melt in the circular ring mold is initially formed. Then the hardware part is taken out and put into cold water for rapid cooling. Since the temperature of the metal melt is relatively high, the temperature of the circular ring mold will become high. When continuously using the circular ring mold for casting processing, it will cause a longer initial forming time for the subsequent cast hardware parts and lower processing efficiency. When using this forming equipment, the metal melt is injected into the interior of the mold 12. The motor or manual drive can be used to drive the disc 1 to drive the mold 12 to rotate, so that the mold 12 filled with the metal melt rotates to one side of the column 3. Then the fourth circular ring 33 is driven to move downward on one side of the column 3. The fourth circular ring 33 moves into the mold 12 to extrude the metal melt in the mold 12. Then the initially formed hardware part in the mold 12 is taken out and put into water for cooling, and the processing of the hardware part can be completed. When the hardware part in the mold 12 is formed, the hardware part is taken out. Then the used mold 12 is rotated to one side of the second circular tube 55. Since the temperature of the just used mold 12 is relatively high, slower cooling of the subsequent hardware parts will occur during subsequent casting processing. At this time, the two second circular tubes 55 are inserted into the first circular tube 123 at the same time, and water is injected into the mold 12 and the cylindrical block 122 through the second circular tube 55 from one end of the third circular tube 551, which can quickly cool the mold 12 and the cylindrical block 122. Then the water inside the mold 12 and the cylindrical block 122 flows out of the second circular tube 55 into the third circular tube 551 and is discharged from the other end of the third circular tube 551. The cooled mold 12 can be used for casting again, which speeds up the forming time of the hardware parts. After each casting, the mold 12 is rotated to one side of the second circular tube 55 for rapid cooling, solving the problem that the mold 12 cannot be quickly cooled, and the continuously used mold 12 has a high temperature, which will cause slower forming of the subsequent hardware parts.

[0038] As Figure 7 shown, a slide table 31 is slidably arranged on one side of the column 3. The lower edge of the slide table 31 is fixedly connected to the fourth circular ring 33 through a plurality of fourth cylindrical rods 32. The fourth circular ring 33 and the fourth cylindrical rods 32 are both hollow structures and communicate with each other. The upper ends of two of the fourth cylindrical rods 32 are fixedly connected to a first hose 34. The first hose 34 respectively slidably penetrates through a first fixing block 35. The first fixing block 35 is fixedly connected to the column 3. The ends of the first hose 34 far from the fourth cylindrical rods 32 are commonly fixedly connected to a first water tank 36.

[0039] Specifically, after rotating the mold 12 filled with molten metal to one side of the column 3, the slide 31 is then driven to drive the fourth circular ring 33 to move downward through the fourth cylindrical rod 32, so that the fourth circular ring 33 moves inside the mold 12 to extrude and form the internal molten metal. When the fourth circular ring 33 contacts the molten metal, the temperature of the fourth circular ring 33 will rise. Water is injected into the fourth circular ring 33 through the first hose 34, so that the fourth circular ring 33 can be quickly cooled. When the fourth circular ring 33 extrudes the upper end of the circular ring workpiece, the upper end of the circular ring workpiece can be cooled.

[0040] As Figure 5 shown, elastic components are respectively arranged inside the first circular tube 123. The elastic components include a third circular ring 1231 fixedly connected to the middle of the first circular tube 123. A tapered block 1232 is slidably arranged in the middle of the third circular ring 1231. One side of the tapered block 1232 is fixedly connected to a second circular plate 1234 through a third cylindrical rod 1233. A plurality of circular holes 1235 are arranged in the middle of the second circular plate 1234. The second circular plate 1234 can slide inside the first circular tube 123, and the second circular plate 1234 is connected to the third circular ring 1231 through a first spring 1236.

[0041] Specifically, when it is necessary to drain or inject water into the mold 12 and the cylindrical block 122, when the second circular tube 55 is inserted into the first circular tube 123, the second circular tube 55 contacts the second circular plate 1234 and pushes the second circular plate 1234 to move to one side, and compresses the first spring 1236. The second circular plate 1234 drives the tapered block 1232 through the third cylindrical rod 1233 to generate a gap between the tapered block 1232 and the third circular ring 1231. At this time, the second circular tube 55 drains water into the first circular tube 123, and the water flows along the circular holes 1235 into the first circular tube 123, and then enters the inside of the first circular tube 123 from the gap between the tapered block 1232 and the third circular ring 1231, and then enters the mold 12 and the cylindrical block 122. Then, the second circular tube 55 is driven to move out of the first circular tube 123, and the first spring 1236 releases its elastic force, pushing the second circular plate 1234 to drive the tapered block 1232 to slide towards the side close to the third circular ring 1231, which can prevent the water inside the mold 12 and the cylindrical block 122 from flowing out.

[0042] As Figure 6 shown, check valves are respectively installed at both ends of the third circular tube 551. Second hoses 552 are respectively fixedly connected to both ends of the third circular tube 551. Second water tanks 56 are respectively fixedly connected to the ends of the second hoses 552 away from the third circular tube 551.

[0043] Specifically, when the second circular tube 55 is inserted into the first circular tube 123 to drain the water inside the mold 12 and the cylindrical block 122, it is discharged from the one-way valve provided at one end of the third circular tube 551. Subsequently, the water is drained into the third circular tube 551 through the one-way valve provided at the other end of the third circular tube 551 and enters the first circular tube 123 through the second circular tube 55.

[0044] As Figure 6 shown, two third circular tubes 551 are commonly fixedly connected with a kidney-shaped block 553. One side of the kidney-shaped block 553 is fixedly connected with an L-shaped block 554. The lower end of the L-shaped block 554 is slidably connected with a second slide rail 555, and the second slide rail 555 is fixedly connected with the bottom plate 6.

[0045] Specifically, by driving the L-shaped block 554 to drive the kidney-shaped block 553 to move towards the mold 12 side, the kidney-shaped block 553 drives the second circular tube 55 to move towards the mold 12 side through the two third circular tubes 551, and the two second circular tubes 55 are respectively inserted into the first circular tube 123 to drain the water inside the mold 12 and the cylindrical block 122, and then re-injected.

[0046] As Figure 8 shown, four corners at the lower end of each cross block 1221 are respectively fixedly connected with a second circular ring 1224 through a second cylindrical rod 1223. The lower end of each first circular ring 121 is commonly fixedly connected with a first circular plate 1212 through a plurality of first cylindrical rods 1211. The first circular plates 1212 are all located above the second circular rings 1224. A cylindrical platform 13 is provided at the lower end of the second circular ring 1224 on one side of the column 3.

[0047] Specifically, when extruding and molding the molten metal in the mold 12, the driving disc 1 is rotated to rotate the mold 12 filled with the molten metal to the upper end of the cylindrical platform 13. The cylindrical platform 13 can support the first circular plate 1212 through the second circular ring 1224, and the first circular plate 1212 supports the first circular ring 121 through the first cylindrical rods 1211 to prevent the first circular ring 121 from falling off due to excessive extrusion.

[0048] As Figure 1 、 Figure 9 shown, a feed pipe 2 is provided on one side of the upper end of the bottom plate 6. The end of the feed pipe 2 is fixedly connected with a storage barrel 21. A material taking assembly is provided on the side of the upper end of the bottom plate 6 away from the feed pipe 2. The material taking assembly includes a conveyor belt 4 installed on the upper end of the bottom plate 6. A rectangular plate 41 is provided on one side of the conveyor belt 4. Two rotating rods 42 are respectively rotatably connected to both sides of the upper end of the rectangular plate 41. The rotating rods 42 are respectively fixedly connected with a first rectangular strip 43, and the two first rectangular strips 43 are in a vertically staggered state.

[0049] Specifically, the molten metal is discharged into the mold 12 through the feed pipe 2 for extrusion molding. The formed ring is rotated to one side of the conveyor belt 4. Then, the first ring 121 is driven to move upward in the mold 12 to push the formed ring workpiece upward. Subsequently, the two rotating rods 42 are driven to rotate towards the middle simultaneously, driving the two first rectangular bars 43 to rotate towards the middle simultaneously, and pushing the ring workpiece to the upper end of the conveyor belt 4 for transmission to the next processing step.

[0050] As Figure 10 、 Figure 11 As shown, a cleaning component is provided on the upper end of the bottom plate 6 on the side away from the column 3. The cleaning component includes a first slide rail 542 fixedly connected to the upper end of the second water tank 56 through an L-shaped bar 543. A first cylindrical bar 51 and a second cylindrical bar 52 are slidably arranged between the two first slide rails 542. A third cylindrical bar 53 is provided at the lower end of the second cylindrical bar 52. A cleaning cloth 5 is sleeved on the outer sides of the first cylindrical bar 51, the second cylindrical bar 52, and the third cylindrical bar 53. The two ends of the third cylindrical bar 53 are rotatably connected to a fourth rectangular block 531. One side of the fourth rectangular block 531 is fixedly connected with a telescopic rod 532 respectively. The two telescopic rods 532 are fixedly connected with a U-shaped bar 533. The U-shaped bar 533 is fixedly connected with the bottom plate 6. Discharge components are respectively provided at the lower ends of the mold 12 near the second water tank 56 and the conveyor belt 4. The discharge component includes a cylindrical barrel 14 fixedly connected to the upper end of the bottom plate 6. An electric telescopic rod 141 is provided in the middle of the cylindrical barrel 14. The electric telescopic rod 141 is fixedly connected with the bottom plate 6.

[0051] Specifically, during the cooling and forming process of the ring workpiece, when the ring workpiece is extruded, the surface of the workpiece deforms, generating debris on the surface of the ring workpiece. After the ring workpiece is taken out, impurities will remain inside the mold 12 and need to be cleaned in time to prevent affecting subsequent processing. When using this forming equipment, after the ring workpiece is taken out, the mold 12 is driven to rotate to the side close to the cleaning cloth 5. Then, the electric telescopic rod 141 is driven to extend to push the first ring 121 upward, so that the first ring 121 is located at the top of the mold 12. Subsequently, the telescopic rod 532 is driven to extend, and the third cylindrical bar 53 is driven to approach the upper end of the first ring 121 through the fourth rectangular block 531. The third cylindrical bar 53 drives the cleaning cloth 5 to slide along the upper end of the first ring 121, and the impurities on the upper end of the first ring 121 can be wiped off.

[0052] As Figure 11As shown, at both ends of the first cylindrical bar 51 and the second cylindrical bar 52, fifth rectangular blocks 54 are respectively connected through damping rotation. The fifth rectangular blocks 54 can respectively slide within the first sliding rails 542. A third spring 541 is fixedly connected between the two first sliding rails 542. At both ends of the first cylindrical bar 51, second rectangular blocks 511 are respectively rotationally connected. The second rectangular blocks 511 are respectively fixedly connected to the fifth rectangular blocks 54. Inside the upper ends of the second rectangular blocks 511, third rectangular blocks 513 are slidably arranged. The third rectangular blocks 513 are fixedly connected to the interiors of the second rectangular blocks 511 through second springs 512. On one side of the third rectangular blocks 513, racks 514 are respectively fixedly connected. At both ends of the second cylindrical bar 52, gears 521 are respectively fixedly connected. The racks 514 can respectively mesh with the gears 521.

[0053] Specifically, when the third cylindrical bar 53 drives the cleaning cloth 5 to move towards the side close to the mold 12, at the same time, the first cylindrical bar 51 drives the third rectangular block 513 and the rack 514 to slide towards the side close to the gear 521 through the second rectangular block 511, and at the same time, the third spring 541 is compressed. The teeth of the rack 514 are helical teeth, and the hypotenuse side slides along the gear 521, causing the third rectangular block 513 to slide upward within the second rectangular block 511 and stretch the second spring 512. Since the second cylindrical bar 52 and the fifth rectangular block 54 are connected through damping, the frictional force is relatively large, and the gear 521 does not rotate at this time. When the third cylindrical bar 53 drives the cleaning cloth 5 to move away from the side of the mold 12, the teeth of the rack 514 mesh with the gear 521. The third spring 541 releases the elastic force to drive the first cylindrical bar 51 to slide away from the side of the mold 12. The first cylindrical bar 51 drives the rack 514 to move, the rack 514 drives the gear 521 to rotate, and the second cylindrical bar 52 rotates, winding the cleaning cloth 5 with impurities wiped on the outer side of the second cylindrical bar 52, and pulling out the clean cleaning cloth 5 provided on the outer side of the first cylindrical bar 51, so that the clean cleaning cloth 5 wraps around the outer side of the third cylindrical bar 53 for convenient next cleaning.

[0054] Embodiment 2

[0055] As Figure 12 shown, compared with Embodiment 1, another implementation manner of the present invention is: The second water tank 56 is fixedly connected with a fourth hose 574. The upper end of the fourth hose 574 is fixedly connected with a third hose 573. The upper end of the third hose 573 is fixedly connected with a second rectangular bar 57. The second rectangular bar 57 is fixedly connected to the U-shaped bar 533 through a third rectangular bar 572. Several nozzles 571 are installed on the side of the second rectangular bar 57 close to the cleaning cloth 5. The inside of the second rectangular bar 57 is a hollow structure.

[0056] Specifically, the water in the second water tank 56 is conveyed to the second rectangular strip 57 through the fourth hose 574 and the third hose 573, and then sprayed out by the nozzle 571 to wet the clean cleaning cloth 5 wound around the outer side of the first cylindrical strip 51. The wetted cleaning cloth 5 has a better cleaning effect.

[0057] Working principle: During processing, the metal melt is discharged into the mold 12 through the feed pipe 2. Then, the driving disc 1 is rotated to rotate the mold 12 filled with the metal melt to the upper end of the cylindrical platform 13. The cylindrical platform 13 can support the first circular plate 1212 through the second circular ring 1224, and the first circular plate 1212 supports the first circular ring 121 through the first cylindrical rod 1211. After extrusion, the extruded ring rotates to one side of the conveyor belt 4. Then, the first circular ring 121 is driven to move upward in the mold 12 to push the formed ring workpiece upward. Subsequently, the two rotating rods 42 are driven to rotate towards the middle at the same time, driving the two first rectangular strips 43 to rotate towards the middle at the same time, and pushing the ring workpiece to the upper end of the conveyor belt 4 to be conveyed to the next processing step.

[0058] Then continue to rotate. When the mold 12 is rotated to the side of the second circular tube 55 and the second circular tube 55 is inserted into the first circular tube 123, the second circular tube 55 contacts the second circular plate 1234 and pushes the second circular plate 1234 to move to one side, and compresses the first spring 1236. The second circular plate 1234 drives the conical block 1232 to generate a gap between the third circular ring 1231 through the third cylindrical rod 1233. The water inside the mold 12 and the cylindrical block 122 is discharged through the one-way valve provided at one end of the third circular tube 551. Then, the water is discharged into the third circular tube 551 through the one-way valve provided at the other end of the third circular tube 551 and enters the first circular tube 123 through the second circular tube 55. Then, the second circular tube 55 is driven to move out of the first circular tube 123, and the first spring 1236 releases its elastic force, pushing the second circular plate 1234 to drive the conical block 1232 to slide towards the side close to the third circular ring 1231, which can prevent the water inside the mold 12 and the cylindrical block 122 from flowing out.

[0059] The water in the second water tank 56 is conveyed to the second rectangular strip 57 through the fourth hose 574 and the third hose 573, and then sprayed out by the nozzle 571 to wet the clean cleaning cloth 5 wound around the outer side of the first cylindrical strip 51. Subsequently, the electric telescopic rod 141 is driven to extend to jack up the first ring 121, so that the first ring 121 is located at the top of the mold 12. Then, the telescopic rod 532 is driven to extend to drive the cleaning cloth 5 to move towards the side close to the mold 12 through the third cylindrical strip 53. At the same time, the first cylindrical strip 51 drives the third rectangular block 513 and the rack 514 to slide towards the side close to the gear 521 through the second rectangular block 511, and at the same time, the third spring 541 is compressed. The teeth of the rack 514 are helical teeth, and the hypotenuse side slides along the gear 521, so that the third rectangular block 513 slides upward in the second rectangular block 511 and stretches the second spring 512. Since the second cylindrical strip 52 and the fifth rectangular block 54 are connected by damping and the friction is large, the gear 521 will not rotate at this time. When the third cylindrical strip 53 drives the cleaning cloth 5 to move away from the mold 12, the teeth of the rack 514 mesh with the gear 521, and the third spring 541 releases elastic force to drive the first cylindrical strip 51 to slide away from the mold 12. The first cylindrical strip 51 drives the rack 514 to move, the rack 514 drives the gear 521 to rotate, and the second cylindrical strip 52 rotates, winding the cleaning cloth 5 with impurities wiped on the outer side of the second cylindrical strip 52, and pulling out the clean cleaning cloth 5 provided on the outer side of the first cylindrical strip 51, so that the clean cleaning cloth 5 wraps around the outer side of the third cylindrical strip 53 for the next cleaning.
