Description

Technical Field

[0001] The utility model relates to the field of melt high-pressure pump systems, in particular to a melt high-pressure pump system. Background Art

[0002] The current pump body casting uses four risers, which will lead to unconcentrated shrinkage compensation heat, which is easy to cause sand blasting and shrinkage of the casting. In addition, pouring from the side is also easy to cause sand blasting, so it needs to be improved. Utility Model Content

[0003] The utility model aims to provide a melt high-pressure pump system to solve the problems raised in the above-mentioned background technology, which has the advantage of changing four small risers into two large risers, thereby concentrating heat and not easily causing shrinkage of castings.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a melt high-pressure pump system, including a straight runner, the lower end of the straight runner is connected to a cross runner, the end of the cross runner away from the straight runner is connected to an endogate, the endogate is connected to a pump body, the upper end of the pump body is provided with a riser, the top of the straight runner is integrally connected with a connecting pipe, a connecting shaft is passed through the middle of the connecting pipe, a sphere is sleeved on the part of the connecting shaft located in the connecting pipe, and an inwardly recessed receiving groove is provided on the side of the sphere.

[0005] By adopting the above technical scheme, the molten steel enters the sprue from the sprue and then slowly flows into the pump body from the bottom. This is not easy to cause sand erosion and shrinkage. In addition, the molten steel entering the sprue needs to be manually quantitatively measured each time, which is very inconvenient. This scheme pre-fixes the connecting shaft to fix the sphere. After the molten steel is introduced from the top of the connecting pipe, it will flow into the containing groove in the sphere. After the molten steel in the containing groove is filled to the opening of the containing groove, the rotating connecting shaft drives the sphere to rotate, thereby allowing the molten steel in the sphere to flow out of the sphere into the sprue, thereby achieving the purpose of quantitative pouring.

[0006] As a further solution of the utility model: the interior of the connecting pipe is fixedly connected with a fixing block sleeved on the outside of the connecting shaft, and the fixing block is provided with a first through groove penetrating the fixing block.

[0007] By adopting the above technical solution, a gap is easily formed between the sphere and the inner wall of the sprue. After the fixed block is installed, the molten steel poured into the sprue will first flow to the upper side of the fixed block and then flow into the first through groove and into the accommodating groove of the sphere.

[0008] As a further solution of the utility model: a second through groove penetrating the connecting shaft is provided on the side of the connecting shaft, a first fixing rod is passed through the second through groove, a third through groove penetrating the first fixing rod is provided at one end of the first fixing rod, the first fixing rod is clamped with a threaded rod through the third through groove, and the threaded rod is threadedly connected to the side of the connecting pipe.

[0009] By adopting the above technical solution, when the accommodating groove is facing upward, the sphere is easy to shake. At this time, it is only necessary to fix the connecting shaft to fix the sphere. When the accommodating groove is facing upward, the opening direction of the second through groove is also facing upward. At this time, the first fixing rod is inserted from the second through groove, and then the threaded rod is passed through the third through groove and the threaded rod is threadedly connected to the side wall of the connecting pipe, thereby limiting the rotation of the connecting shaft.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The molten steel enters the sprue from the sprue and then slowly flows into the pump body from the bottom. This is not easy to cause sand erosion and shrinkage. In addition, the molten steel entering the sprue needs to be manually quantitatively measured each time, which is very inconvenient. This solution pre-fixes the connecting shaft to fix the sphere. After the molten steel is introduced from the top of the connecting pipe, it will flow into the containing groove in the sphere. After the molten steel in the containing groove is filled to the opening of the containing groove, the rotating connecting shaft drives the sphere to rotate, thereby allowing the molten steel in the sphere to flow out of the sphere into the sprue, thereby achieving the purpose of quantitative pouring.

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] In the embodiment of the utility model,

[0017] A melt high pressure pump system, such as Figure 1-Figure 2 As shown, it includes a straight runner 1, the lower end of the straight runner 1 is connected to a cross runner 2, the end of the cross runner 2 away from the straight runner 1 is connected to an endogate 3, the endogate 3 is connected to a pump body 4, the upper end of the pump body 4 is provided with a riser 5, the top of the straight runner 1 is integrally connected with a connecting pipe 6, the middle of the connecting pipe 6 is penetrated by a connecting shaft 7, the part of the connecting shaft 7 in the connecting pipe 6 is sleeved with a sphere 8, and the side of the sphere 8 is provided with an inwardly recessed receiving groove 9.

[0018] A fixing block 10 sleeved on the outside of the connecting shaft 7 is fixedly connected to the interior of the connecting pipe 6 , and the fixing block 10 is provided with a first through groove 11 penetrating through the fixing block 10 .

[0019] The side of the connecting shaft 7 is provided with a second through groove 12 that passes through the connecting shaft 7, and the second through groove 12 is penetrated by a first fixing rod 13, and one end of the first fixing rod 13 is provided with a third through groove 14 that passes through the first fixing rod 13, and the first fixing rod 13 is clamped with a threaded rod 15 through the third through groove 14, and the threaded rod 15 is threadedly connected to the side of the connecting pipe 6.

[0020] Working principle:

[0021] The molten steel enters the ingrowth 3 from the sprue 1 and then slowly flows into the pump body 4 from the bottom. This makes it less likely to cause sand erosion and shrinkage. In addition, the molten steel entering the sprue 1 each time needs to be quantitatively measured manually, which is very inconvenient. In this solution, the connecting shaft 7 is fixed in advance to fix the sphere 8. After the molten steel is introduced from the top of the connecting pipe 6, it will flow into the receiving groove 9 in the sphere 8. After the molten steel in the receiving groove 9 is filled to the opening of the receiving groove 9, the connecting shaft 7 is rotated to drive the sphere 8 to rotate, thereby allowing the molten steel in the sphere 8 to flow out of the sphere 8 and into the sprue 1, thereby achieving the purpose of quantitative pouring.

[0022] There is easily a gap between the sphere 8 and the inner wall of the sprue 1. After the fixing block 10 is provided, the molten steel poured into the sprue 1 will first flow to the upper side of the fixing block 10 and then flow into the first through groove 11 and into the receiving groove 9 of the sphere 8.

[0023] When the accommodating groove 9 is facing upward, the sphere 8 is easy to shake. At this time, it is only necessary to fix the connecting shaft 7 to fix the sphere 8. When the accommodating groove 9 is facing upward, the opening direction of the second through groove 12 is also facing upward. At this time, the first fixing rod 13 is inserted from the second through groove 12, and then the threaded rod 15 is passed through the third through groove 14 and the threaded rod 15 is threadedly connected to the side wall of the connecting pipe 6, thereby limiting the rotation of the connecting shaft 7.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
