Description

Technical Field

[0001] The invention relates to the technical field of metal parts casting, in particular to a metal parts casting and pouring device. Background Art

[0002] Metal casting is a process that injects molten metal into a prefabricated mold, allowing it to cool and solidify to create the desired shape and performance. As a fundamental process in modern manufacturing, casting can be categorized into sand casting, metal mold casting, pressure casting, and precision casting. Sand casting is the most widely used due to its adaptability and low cost. The core technical aspects of this process include mold design and fabrication, smelting quality control, gating system optimization, and heat treatment process development. These factors require comprehensive consideration of parameters such as the fluidity and shrinkage of the molten metal and the permeability of the molding sand.

[0003] Internal pores generated during the casting process of metal parts can significantly affect the mechanical properties and service life of the castings. The presence of pores will destroy the continuity of the metal matrix, leading to increased stress concentration, and easily become the source of crack initiation and expansion under dynamic loads, thereby reducing the fatigue strength and impact toughness of the castings. Especially for critical components that are subjected to high pressure or alternating stress, such as engine cylinders or hydraulic valve bodies, even micron-level pores can cause early failure. Pores will also reduce the effective load-bearing cross-section of the casting, directly affecting its tensile strength and yield strength. Tests have shown that when the porosity exceeds 2%, the strength index of the casting may drop by 15%-20%. In addition, dense pores will deteriorate the density of the casting, which may cause medium leakage in application scenarios requiring air tightness or liquid tightness. Summary of the Invention

By providing the centrifugal mechanism 6, a rotational force can be applied to the multiple casting molds 7 during the casting of metal parts, thereby allowing the liquid metal to fully flow into the inner cavity of the casting mold 7 and to discharge the bubbles inside the liquid metal under high-speed rotation, thereby preventing the metal parts from generating a large number of bubbles after forming. A casting mold 7 is used to shape metal parts. By setting the casting mold 7, it can be connected to the centrifugal mechanism 6.

By setting the heating device 44, it is a prior art that after the power is connected and the switch is turned on, the inner of the storage box 42 is filled with water. The cavity generates high-temperature heat, so that the molten metal will not solidify in the inner cavity of the storage box 42. By setting the track groove 8, the extrusion rod 45 can be limited, so that the extrusion rod 45 can move at the track groove 8 starting from the upper surface of the panel 3, and then when the centrifugal mechanism 6 is working, the extrusion rod 45 is intermittently squeezed, and finally the liquid metal in the inner cavity of the storage box 42 is shaken and flows down quickly. The outer surface of the storage box 42 is provided with a shaking mechanism 41, and the shaking mechanism 41 includes a limiting tube 411, which is fixedly connected to the upper surface of the panel 3. The inner cavity of the limiting tube 411 is slidably connected with a sliding rod 412, and the outer surface of the sliding rod 412 is provided with a spring 413, and the end of the spring 413 is squeezed against the inner wall of the limiting tube 411.

The rotation column 414 is provided so that the rotation circle 415 can be rotated on the outer surface of the rotation column 414, thereby changing the angle between the sliding rod 412, the fixing frame 416 and the storage box 42. The number of the shaking mechanism 41 is four, which are evenly distributed around the storage box 42, so that the storage box 42 can quickly restore balance after shaking.

The lower surface of the rotating hollow ball 47 is fixedly connected to the connecting box 48. The connecting box 48 is fixedly connected to the axis of the panel 3. The lower surface of the connecting box 48 is penetrated by a guide tube 49. By providing the limiting ring 46, it can be rotated on the outer surface of the rotating hollow ball 47.The limiting ring 46 then drives the storage box 42 to shake on the upper surface of the panel 3. By providing the connecting box 48 and the guide pipe 49, the liquid metal in the inner cavity of the storage box 42 can enter the inner cavity of the centrifugal mechanism 6 through the connecting box 48 and the guide pipe 49.

By providing the arc-shaped track plate 65, when the transfer box 63 rotates and when the arc-shaped track plate 65 is directly below the extrusion rod 45, the arc-shaped track plate 65 squeezes the bottom end of the extrusion rod 45, thereby causing the extrusion rod 45 to move upward. Eventually, the storage box 42 will shake. The upper surface of the transfer box 63 is fixedly connected to a wrapping plate 66, and the inner wall of the wrapping plate 66 is fixedly connected to a first rolling bearing 67. The inner ring of the first rolling bearing 67 is fixedly connected to the outer surface of the guide tube 49. The bottom of the outer surface of the transfer box 63 is penetrated by a threaded ring 68. By setting the wrapping plate 66, the first rolling bearing 67 and the transfer box 63 can be connected together. By setting the first rolling bearing 67, the transfer box 63 can rotate stably around the guide tube 49 when it rotates.

[0023] The casting mold 7 includes a semicircular connecting cylinder 71, which is symmetrical in two directions. The semicircular connecting cylinder 71 is threadedly connected to the inner circle of the thread ring 68. The inner wall of the semicircular connecting cylinder 71 is fixedly connected to the first clamping groove 79. The side of the semicircular connecting cylinder 71 away from the first clamping groove 79 is fixedly connected to the first clamping plate 78. By setting the thread ring 68, the casting mold 7 can be limited, so that when the casting mold 7 is casting metal parts, the casting mold 7 is connected to the transfer box 63 through the thread ring 68. By setting the semicircular connecting cylinder 71, the two can be spliced ​​together to achieve The first latching groove 79 and the first latching plate 78 are provided to facilitate the removal of the metal parts after the molding. When the two semicircular connecting tubes 71 are spliced ​​together, the first latching plate 78 can be inserted into the inner cavity of the first latching groove 79, thereby tightly connecting the semicircular connecting tubes 71 together. The side of the semicircular connecting tube 71 away from the thread ring 68 is fixedly connected to the semi-cylindrical mold 72, and the inner wall of the semi-cylindrical mold 72 is fixedly connected to the shaping shell 710. The side of the upper surface of the shaping shell 710 is fixedly connected to the second latching groove 711. The side of the upper surface of the shaping shell 710 away from the second latching groove 711 The second clamping plate 712 is fixedly connected. By setting the semi-cylindrical mold 72, the two shaping shells 710 can form a sealed space when they are spliced ​​together, thereby forming the metal parts. By setting the second clamping groove 711 and the second clamping plate 712, they can be connected together, thereby making the two semi-cylindrical molds 72 tightly connected together. The outer surface of the semi-cylindrical mold 72 is provided with a threaded groove 73, and the threaded groove 73 is threadedly connected to a threaded shell 74. The outer surface of the threaded shell 74 is fixedly connected to a handle 75. The outer surface of the threaded shell 74 is fixedly connected to a second rolling bearing 76. The second rolling shaft The outer surface of the bearing 76 is fixedly connected with a sliding column 77, and the upper surface of the connecting plate 5 is provided with a track ring 9. The sliding column 77 is frictionally adapted to the track ring 9. By setting the threaded groove 73, the threaded shell 74 can be limited so that the threaded shell 74 can be rotated to achieve the effect of tightly connecting the two semi-cylindrical molds 72 together. By setting the second rolling bearing 76, the sliding column 77 can generate stable rotation on the outer surface of the threaded shell 74, so that the sliding column 77 can be in contact with the track ring 9. By setting the sliding column 77, it can move in the inner cavity of the track ring 9, so that the semi-cylindrical mold 72 can rotate stably.

[0024] Working principle: When in use, the operator spirally rotates the semicircular connecting cylinder 71 into the inner cavity of the threaded ring 68, and then rotates the threaded shell 74 to the outer surface of the semi-cylindrical mold 72, and makes the sliding column 77 contact with the inner cavity of the track ring 9, and then connects the stepping motor 61 to the power supply and turns on the switch, so that the rotating rod 62 drives the transfer box 63 and the casting mold 7 to rotate; then the liquid metal melted in the high-temperature furnace is poured into the inner cavity of the storage box 42. When the transfer box 63 rotates, the arc-shaped track plate 65 will be squeezed with the bottom end of the extrusion rod 45, and finally the extrusion rod 45 and the storage box 42 will shake. When the sliding rod 412 moves in the inner cavity of the limiting tube 411, the spring 413 will store elastic potential energy and return to its original position later. When the storage box 42 shakes, the liquid metal inside will flow into the inner cavity of the transfer box 63 through the guide tube 49, and finally flow into the inner cavity of the semi-cylindrical mold 72. Under high-speed centrifugation, the bubbles inside are thrown out, and finally the metal parts after molding will contain no pores.
