Abstract
Description
Technical Field:
[0001] The utility model relates to the technical field of casting equipment, and more specifically, to a ductile iron molten metal pouring device. Background Art:
[0002] Ductile iron is a high-strength cast iron material developed in the 1950s of the 20th century. Its comprehensive performance is close to that of steel. Based on its excellent performance, it has been successfully used to cast some parts with complex stress, high requirements for strength, toughness, and wear resistance.
[0003] Therefore, ductile iron is used in many casting industries. When casting, it needs to be heated and melted to about 1400 °C, and then poured into a molten metal placement barrel. For some small castings, horizontal holding rods are fixed at the left and right ends of the molten metal placement barrel. Two operators hold the horizontal holding rods, and the ductile iron molten metal is poured into the molten metal placement barrel. When in use, two people need to move it to the casting mold, turn it over, and pour it. It needs to be manually aligned with the feeding port of the casting mold for pouring. When not aligned, problems are likely to occur. Another method is to hoist the connecting rod of the molten metal placement barrel onto the hook of a crane, support the molten metal placement barrel by the crane, and then manually turn and pour the molten metal placement barrel. However, since it is in a state of being lifted by the hook of the crane and is prone to shaking, when manually turning and pouring the molten metal placement barrel, it is easy to generate shaking, causing the discharge end of the molten metal placement barrel to deviate from the feeding port of the mold, thus affecting the casting effect. The molten metal is easily splashed out, resulting in waste and posing a safety hazard to the surrounding area. Summary of the Utility Model:
[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a ductile iron molten metal pouring device. It can ensure that the molten metal placement barrel in the placement sleeve can move left and right along the cross beam, and the discharge port during pouring can be aligned with the feeding port of the mold that has been placed in front of it. When moving, it will not shake, which can ensure accurate pouring, convenient pouring, and high safety.
[0005] The solution for the utility model to solve the above technical problems is:
[0006] A ductile iron molten metal pouring device includes two vertically adjustable rods arranged left and right. Lift sleeves are installed on both of the two vertically adjustable rods, and both ends of a cross beam are fixed to the two lift sleeves;

A through hole extending forward and backward is formed in the lower part of the vertical holding rod. The through hole communicates with and is aligned with a jack extending forward and backward formed on the inner side wall of the groove. A positioning pin is inserted into the through hole and the jack.
[0009] A radially extending edge is formed on the outer side wall at the top end of the placing sleeve. The molten metal placing barrel is inserted into the placing sleeve. The radially bent edge formed on the outer side wall at the top of the molten metal placing barrel is pressed against the top surface of the radially extending edge.
[0010] External threads are formed on the outer side wall of the vertical adjusting rod. The lifting sleeve body is screwed on the external threads of the vertical adjusting rod. Placing connecting blocks are fixed at the middle parts of the opposite wall surfaces of the two lifting sleeve bodies. A downward extending slot is formed at the middle part of the top surfaces of the two placing connecting blocks. The opposite ends of the two slots extend out of the opposite end surfaces of the two placing connecting blocks.

[0011] The cross section of the transverse beam is rectangular. A transverse through hole with a rectangular cross section is formed in the middle part of the transverse adjusting sleeve. The transverse beam is inserted into the transverse through hole and is matched with the transverse through hole.
[0012] The prominent effect of the present utility model is:
[0013] It can ensure that the molten metal placing barrel in the placing sleeve can move left and right along the transverse beam, and the discharge port during its tilting can be aligned with the feed port of the mold that has been placed in front of it.

[0019] Furthermore, external threads are formed on the outer side walls of the vertical adjusting rods 10, and lifting sleeve bodies 20 are screwed on the external threads of the vertical adjusting rods 10. A placing connection block 21 is fixed in the middle of the opposite wall surfaces of the two lifting sleeve bodies 20. A downwardly extending slot 22 is formed in the middle of the top surface of the two placing connection blocks 21. The left and right parts of a transverse beam 30 are inserted into the corresponding slots 22 and fixedly connected by bolts.
[0020] A transverse adjusting sleeve 40 is inserted on the transverse beam 30. Side vertical plates 41 are fixed on the top surfaces of both the left and right parts of the transverse adjusting sleeve 40. A placing sleeve 50 is located between the two side vertical plates 41. Connecting shafts 51 are fixed at both the left and right ends of the placing sleeve 50. The connecting shafts 51 are movably connected to the corresponding side vertical plates 41 through bearings. The outer ends of the connecting shafts 51 extend out of the corresponding side vertical plates 41 and are fixed with connecting arms 52 extending backward. An intermediate connecting rod 53 is arranged between the rear ends of the two connecting arms 52, and both ends of the intermediate connecting rod 53 are fixed at the rear parts of the two connecting arms 52;
[0021] A vertical holding rod 54 is fixed to the bottom end of the middle of the middle connecting rod 53. A horizontal fixing plate 42 is fixed to the middle of the rear wall surface of the horizontal adjusting sleeve 40. A vertical block 43 is fixed to the top surface of the rear part of the horizontal fixing plate 42. A groove is formed on the rear wall surface at the top of the vertical block 43. The front part of the lower part of the vertical holding rod 54 is inserted into the groove, and its front wall surface is pressed against the inner side wall of the groove. A through hole extending forward and backward is formed in the lower part of the vertical holding rod 54. The through hole communicates and aligns with a jack extending forward and backward formed on the inner side wall of the groove. A positioning pin 55 is inserted into the through hole and the jack. A holding part with an outer diameter larger than the outer diameter of the positioning pin 55 is formed on the rear part of the positioning pin 55. The front wall surface of the holding part is pressed against the rear wall surface of the vertical holding rod 54.
[0022] Furthermore, a radially extending edge 56 is formed on the outer side wall at the top end of the placing sleeve 50. The molten metal placing barrel 100 is inserted into the placing sleeve 50.

Then, the positioning pin 55 is pulled out, and the vertical holding rod 54 can be manually held to turn the molten metal placing barrel 100 forward and pour it (since it is casting small metal materials, the weight of the molten metal placing barrel 100 filled with molten metal can also be operated by a single operator). At this time, the molten metal flowing out of the discharge end of the molten metal placing barrel 100 will accurately pour into the feed port of the corresponding casting mold to complete the casting. Its operation is convenient, the casting is accurate, and there is no shaking.
[0026] After processing, the vertical holding rod 54 can be held to turn the molten metal placing barrel 100 backward to its original position, fixed by the positioning pin 55, and then the molten metal placing barrel 100 is moved left and right along the transverse beam 30 so that the material end of the molten metal placing barrel 100 is directly behind the feed port of another corresponding casting mold to perform subsequent operations. Its operation is convenient and only requires a single operator, which is very convenient.
