Description

Technical Field

[0001] The utility model belongs to the technical field of pig iron casting, in particular to a pig iron casting device. Background Art

[0002] Pig iron generally refers to an iron alloy with a carbon content of 2-4.3%, also known as cast iron. In addition to carbon, pig iron also contains silicon, manganese, and small amounts of sulfur and phosphorus. It is cast, not forgeable. The carbon in cast pig iron exists in the form of flake graphite, resulting in a gray fracture, commonly known as gray iron. Because graphite is soft and lubricating, cast pig iron exhibits excellent cutting, wear resistance, and casting properties. However, its tensile strength is insufficient, so it cannot be forged or rolled, and is therefore used only to manufacture various castings, such as machine tool bases and pipes.

[0003] In the process of casting pig iron, a mold is needed to cast the pig iron to produce the corresponding product. However, when casting the pig iron, the mold is often driven by only one power system, and the power applies most of the force to the middle position of the mold, so that there is a problem of defective casting on both sides of the mold. Therefore, the utility model proposes a pig iron casting device to solve the above problem. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] When pig iron needs to be cast, the die head is replaced with the desired casting style. The pig iron is then placed on a workbench, and the hydraulic cylinder is activated to extend, driving the die head downward. Simultaneously, the drive hydraulic cylinder is activated, which contracts and drives the second connecting rod downward, thereby driving the first connecting rod downward. The downward movement of the first connecting rod then drives the bottom side of the connected die head downward, achieving the purpose of the die head casting the pig iron. Because the drive hydraulic cylinder, the first connecting rod, the second connecting rod, and the third connecting rod form a drive system, each with a drive system on the left and right sides of the frame, the center and sides of the die head are evenly stressed, enabling the casting of all pig iron positions to be completed without the risk of defective products.

[0029] See also Figures 1 to 3 The utility model provides a technical solution: a pig iron casting device, including a frame 1 and a mold assembly 4; the frame 1 is arranged vertically, and a driving assembly 3 is provided on the top of the frame 1, and the driving assembly 3 includes a hydraulic cylinder 31; the mold assembly 4 includes a mold head 41, the mold head 41 is connected to the output end of the hydraulic cylinder 31, and a guide rod 46 is provided on the side of the mold head 41, and the mold head 41 is slidably connected to the guide rod 46, the mold head 41 is connected to the first connecting rod 43, the first connecting rod 43 is connected to the second connecting rod 44, the second connecting rod 44 is connected to the third connecting rod 45, the third connecting rod 45 is fixedly connected to the frame 1, the second connecting rod 44 is connected to the output end of the driving hydraulic cylinder 42, and the driving hydraulic cylinder 42 is provided on the side of the frame 1; a workbench 2 is provided inside the frame 1.

[0030] In this embodiment, when it is necessary to cast pig iron, the die head 41 is replaced with the desired casting style, the pig iron is then placed on the workbench 2, the hydraulic cylinder 31 is activated and extended, and the hydraulic cylinder 31 drives the die head 41 downward. At the same time, the driving hydraulic cylinder 42 is activated and the driving hydraulic cylinder 42 contracts, driving the second connecting rod 44 downward, thereby driving the first connecting rod 43 downward. At this time, the downward movement of the first connecting rod 43 drives the bottom side of the connected die head 41 downward, achieving the purpose of the die head 41 casting the pig iron. Because the driving hydraulic cylinder 42, the first connecting rod 43, the second connecting rod 44 and the third connecting rod 45 form a drive system, and a drive system is provided on both sides of the frame 1, the center position and the two sides of the die head 41 are evenly stressed, and the pig iron can be cast in various positions without the problem of defective products. When the casting is completed, the hydraulic cylinder 31 is activated and retracted, and the driving hydraulic cylinder 42 is activated and extended, to reset the die head 41. The above actions are repeated to complete the pig iron casting.

[0031] For further information, see Figure 1 The workbench 2 includes a base 21 , which is arranged on the bottom surface of the frame 1 , and the workbench 2 is arranged on the base 21 .

[0032] In this embodiment, the base 21 is arranged on the inner bottom surface of the frame 1, and a workbench 2 is provided on the base 21. The base 21 provides support and stability for the workbench 2. Pig iron is provided on the workbench 2 for casting, and a positioning and limiting mechanism is provided on the workbench 2 to prevent the pig iron from shifting during casting.

[0033] For further information, see Figure 1 There are two driving hydraulic cylinders 42 , and the two driving hydraulic cylinders 42 are relatively distributed on both sides of the frame 1 .

[0034] For further information, see Figure 1 The first connecting rod 43, the second connecting rod 44 and the third connecting rod 45 form a connecting rod group. There are two connecting rod groups, and the two connecting rod groups are relatively distributed on both sides of the frame 1.

[0035] In this embodiment, since the driving hydraulic cylinder 42, the first connecting rod 43, the second connecting rod 44 and the third connecting rod 45 form a driving system, a driving system is provided on the left and right sides of the frame 1. In this way, the middle position and the two side positions of the mold head 41 are evenly stressed, and the casting of each position of the pig iron can be completed, and the problem of defective products is not easy to occur.

[0036] For further information, see Figure 1 The first connecting rod 43 is rotatably connected to the second connecting rod 44 , and the second connecting rod 44 is rotatably connected to the third connecting rod 45 .

[0037] In this embodiment, one end of the second connecting rod 44 is rotatably connected to the first connecting rod 43, and the other end is rotatably connected to the third connecting rod 45. In this way, when the output end of the hydraulic cylinder 42 drives the second connecting rod 44 to move, the first connecting rod 43 will move the mold head 41 up and down.

[0038] Furthermore, the hydraulic cylinder 42 is driven to extend and retract to drive the second connecting rod 44 to rotate, thereby driving the first connecting rod 43 to rotate. The rotation of the first connecting rod 43 drives the mold head 41 to rise and fall.

[0039] In this embodiment, the hydraulic cylinder 31 is started to extend, and the hydraulic cylinder 31 drives the mold head 41 to descend. At the same time, the driving hydraulic cylinder 42 is started, and the driving hydraulic cylinder 42 contracts to drive the second connecting rod 44 to move downward, thereby driving the first connecting rod 43 to move downward. At this time, the downward movement of the first connecting rod 43 drives the bottom side of the connected mold head 41 to move downward, thereby achieving the purpose of the mold head 41 casting the pig iron mold. Otherwise, the mold head 41 is reset.

[0040] The working principle and use process of the present invention are as follows: when it is necessary to cast pig iron, the die head 41 is replaced with the style of the required casting, and then the pig iron is placed on the workbench 2, the hydraulic cylinder 31 is started and extended, and the hydraulic cylinder 31 drives the die head 41 to descend, and the driving hydraulic cylinder 42 is started at the same time. The driving hydraulic cylinder 42 contracts and drives the second connecting rod 44 to move downward, thereby driving the first connecting rod 43 to move downward. At this time, the downward movement of the first connecting rod 43 drives the bottom side of the connected die head 41 to move downward, achieving the purpose of the die head 41 casting the pig iron. Since the driving hydraulic cylinder 42, the first connecting rod 43, the second connecting rod 44 and the third connecting rod 45 form a drive system, a drive system is provided on both sides of the frame 1. In this way, the middle position and the two sides of the die head 41 are evenly stressed, and the casting of each position of the pig iron can be completed, and the problem of defective products is not likely to occur; when the casting is completed, the hydraulic cylinder 31 is started to contract and the driving hydraulic cylinder 42 is started to extend, and the die head 41 is reset. The above actions are repeated to achieve the pig iron casting.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
