The metal hardware casting device, as the core equipment of casting technology, is a device that injects molten metal into the mold and forms the metal material into the desired shape and size in the mold through the solidification and cooling process.

DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0035] Example 1

[0036] like Figure 1-Figure 7As shown, the metal hardware casting forming equipment provided by the embodiment of the application comprises a disc 1, the middle part of the lower end of the disc 1 is rotatable on the upper end of a bottom plate 6 through a support column 11, a vertical column 3 is fixedly connected to one side of the upper end of the bottom plate 6, a fourth circular ring 33 is slidably arranged on one side of the vertical column 3, a plurality of molds 12 are fixedly connected to the edges of the disc 1, a first circular ring 121 is slidably arranged in the middle part of each mold 12, a cylindrical block 122 is arranged in the middle part of the first circular ring 121, a cross block 1221 is fixedly connected to the lower end of the cylindrical block 122, the cross block 1221 is fixedly connected to the disc 1 through first rectangular blocks 1222 at the four corners of the cross block 1221, the cross block 1221 and the middle part of the cylindrical block 122 are both hollow structures and are in communication with each other, the middle part of each mold 12 is a hollow structure, first circular pipes 123 are fixedly connected to one side of the cross block 1221 and one side of the mold 12 respectively, a water changing assembly is arranged on one side of the upper end of the bottom plate 6, the water changing assembly comprises two second circular pipes 55 which are slidably arranged on the upper end of the bottom plate 6, and third circular pipes 551 are fixedly connected to the ends of the second circular pipes 55 which are away from the disc 1.

[0037] Specifically, when processing hardware, the casting molding method is generally used for processing. When casting hardware in the prior art, the ring mold is first prepared, and then the metal melt is injected into the ring mold. Then, the hardware is taken out after the metal melt is cooled and solidified, so that the metal melt in the ring mold is initially formed, and then the hardware is taken out and put into cold water for rapid cooling. Due to the high temperature of the metal melt, the temperature of the ring mold will become high. When the ring mold is used continuously for casting processing, it will cause the initial forming time of the subsequent cast hardware to be longer and the processing efficiency is lower. When using the present molding equipment, the metal melt is injected into the mold 12, and the motor or manual drive disc 1 can be used to drive the mold 12 to rotate, so that the mold 12 filled with the metal melt is rotated to the side of the column 3, and then the fourth ring 33 is driven to move downward on the side of the column 3. The fourth ring 33 moves into the mold 12, and the metal melt in the mold 12 is squeezed. Then the hardware that is initially formed inside the mold 12 is taken out and put into water for After cooling, the hardware can be processed. When the hardware inside the mold 12 is formed, the hardware is taken out and the used mold 12 is rotated to the side of the second round tube 55. Since the temperature of the mold 12 just used is high, the subsequent casting process will cause the subsequent hardware to cool slowly. At this time, the two second round tubes 55 are inserted into the first round tube 123 at the same time, and water is injected into the mold 12 and the cylindrical block 122 through the second round tube 55 from one end of the third round tube 551. The cylindrical block 122 is cooled down quickly, and 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 cast again, which speeds up the molding time of the hardware. After each casting, the mold 12 is rotated to the side of the second circular tube 55 for rapid cooling, which solves the problem that the mold 12 cannot be cooled down quickly. Continuous use of the mold 12 will result in a high temperature, which will cause subsequent hardware molding to be slow.

[0038] like Figure 7 As shown, a slide 31 is slidingly provided on one side of the column 3, and the lower edge of the slide 31 is fixedly connected to the fourth ring 33 through a plurality of fourth cylindrical rods 32. The fourth ring 33 and the fourth cylindrical rod 32 are both hollow structures and are interconnected, wherein the upper ends of two fourth cylindrical rods 32 are fixedly connected to the first hoses 34, and the first hoses 34 slide through the first fixed blocks 35 respectively, and the first fixed blocks 35 are fixedly connected to the column 3, and the first hoses 34 are fixedly connected to the first water tank 36 at one end away from the fourth cylindrical rods 32.

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

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

[0041] Specifically, when the mold 12 and the cylindrical block 122 need to be drained or filled with water, 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 squeezes the first spring 1236. The second circular plate 1234 drives the conical block 1232 and the third circular ring 1231 through the third cylindrical rod 1233 to create a gap. At this time, the second circular tube 55 drains water into the first circular tube 123, and the water flows along the circular hole 123 The water flows into the first circular tube 123, then enters the first circular tube 123 through the gap between the conical block 1232 and the third circular ring 1231, and then enters the mold 12 and the cylindrical block 122. The second circular tube 55 is then driven to move out of the first circular tube 123. The first spring 1236 releases its elastic force, pushing the second circular plate 1234 to slide the conical block 1232 toward the third circular ring 1231 through the third cylindrical rod 1233, thereby preventing the water inside the mold 12 and the cylindrical block 122 from flowing out.

[0042] like Figure 6 As shown, one-way valves are installed inside both ends of the third circular tube 551 , and second hoses 552 are fixedly connected to both ends of the third circular tube 551 . One end of the second hose 552 away from the third circular tube 551 is fixedly connected to the second water tank 56 .

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

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

[0045] Specifically, by driving the L-shaped block 554 to move the waist-shaped block 553 toward the side close to the mold 12, the waist-shaped block 553 drives the second round tube 55 to move toward the side close to the mold 12 through the two third round tubes 551, and the two second round tubes 55 are respectively inserted into the first round tube 123 to discharge the water inside the mold 12 and the cylindrical block 122, and then re-inject it.

[0046] like Figure 8 As shown, the four corners of the lower end of each cross block 1221 are fixedly connected to the second circular ring 1224 through the second cylindrical rod 1223, and the lower end of each first circular ring 121 is fixedly connected to the first circular plate 1212 through several first cylindrical rods 1211. The first circular plates 1212 are all located at the upper end of the second circular ring 1224. A cylindrical platform 13 is provided at the lower end of the second circular ring 1224 located on the side of the column 3.

[0047] Specifically, when the molten metal in the mold 12 is extruded, the driving disc 1 rotates to rotate the mold 12 containing the molten metal to the upper end of the cylindrical table 13. The cylindrical table 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 to prevent the first circular ring 121 from falling off due to excessive extrusion.

[0048] like Figure 1 、 Figure 9 As shown, a feed pipe 2 is provided on one side of the upper end of the bottom plate 6, and a storage barrel 21 is fixedly connected to the end of the feed pipe 2. 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, and a rectangular plate 41 is provided on one side of the conveyor belt 4. The two sides of the upper end of the rectangular plate 41 are respectively rotatably connected to rotating rods 42, and the rotating rods 42 are respectively fixed to first rectangular bars 43, and the two first rectangular bars 43 are in an up and down staggered state.

[0049] Specifically, the metal melt is discharged into the mold 12 through the feed pipe 2 for extrusion molding, and the extruded ring is rotated to the 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, and then the two rotating rods 42 are driven to rotate toward the middle at the same time, driving the two first rectangular bars 43 to rotate toward the middle at the same time, pushing the ring workpiece to the upper end of the conveyor belt 4 and transmitting it to the next processing step.

[0050] like Figure 10 、 Figure 11 As shown, a cleaning assembly is provided on the side of the upper end of the bottom plate 6 away from the column 3, and the cleaning assembly includes a first slide rail 542 fixed 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, and a third cylindrical bar 53 is provided at the lower end of the second cylindrical bar 52, and a cleaning cloth 5 is commonly sheathed on the outer sides of the first cylindrical bar 51, the second cylindrical bar 52, and the third cylindrical bar 53, and a fourth rectangular block 53 is rotatably connected to both ends of the third cylindrical bar 53, and a telescopic rod 532 is respectively fixed to one side of the fourth rectangular block 531, and the two telescopic rods 532 are commonly fixed to a U-shaped bar 533, and the U-shaped bar 533 is fixed to the bottom plate 6, and a discharging assembly is respectively provided at the lower end of the mold 12 near the second water tank 56 and the conveyor belt 4. The discharging assembly includes a cylindrical barrel 14 fixed to the upper end of the bottom plate 6, and an electric telescopic rod 141 is provided in the middle of the cylindrical barrel 14, and the electric telescopic rod 141 is fixed to the bottom plate 6.

[0051] Specifically, during the cooling and forming process of the annular workpiece, when the annular workpiece is squeezed, the surface of the workpiece is deformed, which will cause debris to be generated on the surface of the annular workpiece. After the annular 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 annular workpiece is taken out, the mold 12 is driven to rotate to the side close to the cleaning cloth 5, and 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, and then 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] like Figure 11As shown, the first cylindrical bar 51 and the second cylindrical bar 52 are respectively connected to the fifth rectangular block 54 at both ends through damping rotation, and the fifth rectangular block 54 can slide in the first slide rail 542 respectively. A third spring 541 is fixed between the two first slide rails 542, and the second rectangular blocks 511 are respectively rotatably connected at both ends of the first cylindrical bar 51. The second rectangular blocks 511 are respectively fixed to the fifth rectangular block 54, and a third rectangular block 513 is slidingly provided inside the upper end of the second rectangular block 511. The third rectangular block 513 is fixed to the inside of the second rectangular block 511 through the second spring 512. A rack 514 is respectively fixed to one side of the third rectangular block 513, and a gear 521 is respectively fixed to both ends of the second cylindrical bar 52, and the rack 514 can respectively engage with the gear 521.

[0053] Specifically, when the third cylindrical bar 53 drives the cleaning cloth 5 to move toward the side close to the mold 12, the first cylindrical bar 51 drives the third rectangular block 513 and the rack 514 to slide toward the side close to the gear 521 through the second rectangular block 511, and at the same time squeezes the third spring 541. The teeth of the rack 514 are helical teeth, and the helical side slides along the gear 521, causing the third rectangular block 513 to slide upward in 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 by damping, the friction 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 to the side away from the mold 12, the teeth of the rack 514 engage with the gear 521, and the third spring 541 releases the elastic force to drive the first cylindrical bar 51 to slide to the side away from the mold 12. The first cylindrical bar 51 drives the rack 514 to move, and the rack 514 drives the gear 521 to rotate. The second cylindrical bar 52 rotates, and the cleaning cloth 5 with impurities wiped off is wrapped around the outside of the second cylindrical bar 52, and the clean cleaning cloth 5 provided on the outside of the first cylindrical bar 51 is pulled out, so that the clean cleaning cloth 5 is wrapped around the outside of the third cylindrical bar 53, which is convenient for cleaning next time.

[0054] Example 2

[0055] like Figure 12 As shown, in contrast to Example 1, another embodiment of the present invention is: the second water tank 56 is fixedly connected to the fourth hose 574, the upper end of the fourth hose 574 is fixedly connected to the third hose 573, the upper end of the third hose 573 is fixedly connected to the second rectangular bar 57, the second rectangular bar 57 is fixedly connected to the U-shaped bar 533 through the third rectangular bar 572, and a plurality of nozzles 571 are installed on the side of the second rectangular bar 57 close to the cleaning cloth 5, and the interior of the second rectangular bar 57 is a hollow structure.

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

[0057] Working principle: during processing, the feed pipe 2 discharges the molten metal into the mold 12, and then the disc 1 is driven to rotate so that the mold 12 filled with the molten metal rotates to the upper end of the cylindrical table 13. The cylindrical table 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 the extrusion is completed, the extruded circular ring rotates to the side of the conveyor belt 4, and then the first circular ring 121 is driven to move upward in the mold 12 to eject the formed circular ring workpiece upward, and then the two rotating rods 42 are driven to rotate toward the middle at the same time, driving the two first rectangular bars 43 to rotate toward the middle at the same time, pushing the circular ring workpiece to the upper end of the conveyor belt 4 and transmitting it to the next processing step;

[0058] Then continue to rotate, rotate 12 to the side of the second tube 55, and when the second tube 55 is inserted into the first tube 123, the second tube 55 contacts the second circular plate 1234 and pushes the second circular plate 1234 to move to one side, and squeezes the first spring 1236. The second circular plate 1234 drives the conical block 1232 and the third ring 1231 through the third cylindrical rod 1233 to create a gap. The water inside the mold 12 and the cylindrical block 122 is discharged from the third circular tube 551. The water is discharged through the one-way valve, and then 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 from the second circular tube 55. Then, the second circular tube 55 is driven to move out of the first circular tube 123. The first spring 1236 releases its elastic force, pushing the second circular plate 1234 to slide the conical block 1232 toward the side close to the third circular ring 1231 through the third cylindrical rod 1233, thereby preventing the water inside the mold 12 and the cylindrical block 122 from flowing out.

[0059] The water in the second water tank 56 is transported to the second rectangular bar 57 through the fourth hose 574 and the third hose 573, and then the nozzle 571 sprays water to wet the clean cleaning cloth 5 wrapped around the outside of the first cylindrical bar 51, and 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 on the top of the mold 12, and then the telescopic rod 532 is driven to extend through the third cylindrical bar 53 to drive the cleaning cloth 5 to move closer 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 closer to the gear 521 through the second rectangular block 511, and at the same time squeezes the third spring 541. 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 on the second rectangular block 511. The second cylindrical bar 52 is connected to the fifth rectangular block 54 by a damping connection, and the friction force is large, so the gear 521 does not rotate at this time. When the third cylindrical bar 53 drives the cleaning cloth 5 to move to the side away from the mold 12, the teeth of the rack 514 engage with the gear 521, and the third spring 541 releases the elastic force to drive the first cylindrical bar 51 to slide to the side away from the mold 12. The first cylindrical bar 51 drives the rack 514 to move, and the rack 514 drives the gear 521 to rotate. The second cylindrical bar 52 rotates, and the cleaning cloth 5 with impurities attached to it is wiped and wrapped around the outside of the second cylindrical bar 52, and the clean cleaning cloth 5 provided on the outside of the first cylindrical bar 51 is pulled out, so that the clean cleaning cloth 5 is wrapped around the outside of the third cylindrical bar 53, which is convenient for cleaning next time.
