Description

Technical Field

[0001] The utility model relates to the field of casting systems, in particular to a flat valve cover casting system. Background Art

[0002] The riser of the current valve casting process is placed sideways, which makes the valve cover neck easy to shrink, the upper and lower wall thicknesses are uneven, and the inner hole becomes elliptical, so it needs to be improved. Utility Model Content

[0003] The purpose of the present invention is to provide a flat valve cover casting system to solve the problems raised in the above-mentioned background technology, which has the advantage that the neck of the valve cover is not easily shrunk.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flat valve cover casting system, comprising a main runner, the main runner is connected to a secondary runner, the secondary runner is connected to a blind riser, the blind riser is connected to the valve cover, an exposed riser is arranged above the valve cover, and also comprises a placement plate at the bottom, a sliding rod is passed through the middle of the placement plate, and a handle is integrally connected to one end of the sliding rod.

[0005] By adopting the above technical solution and casting the valve cover upright, it is possible to avoid the problems of the valve cover neck being easily loosened, the upper and lower wall thicknesses being uneven, and the inner hole becoming elliptical. The specific method is to allow the molten steel to enter the blind riser from the runner and then flow into the valve cover and the exposed riser, thereby ensuring that the sand blasting and neck of the casting will not shrink, the upper and lower wall thicknesses will not be uneven, and the inner hole will not become elliptical, thereby improving the quality of the casting. When it needs to be moved, hold the handle to drive the sliding rod to move and then drive the placement plate to move.

[0006] As a further solution of the present invention: one end of the sliding rod in the placing plate is integrally connected to the limiting plate, a first sliding groove for sliding of the sliding rod is provided inside the placing plate, the placing plate is provided with a second sliding groove which is located on one side of the first sliding groove and is connected to the first sliding groove, a cross block is integrally connected to the side of the sliding rod, a spring is provided on one side of the cross block, and the other end of the spring is connected to the bottom of the second sliding groove.

[0007] By adopting the above technical solution, pulling the sliding rod drives the limit plate to move outward and drives the cross block to move at the same time. The movement of the cross block will compress the spring. When no force is applied to the sliding rod, the sliding rod returns to its original position under the action of the spring, that is, the sliding rod will retract into the placement plate, reducing the occupied space. The setting of the limit plate prevents the sliding rod from separating from the placement plate.

[0008] As a further solution of the present invention: a cover is provided at the opening of the main runner, and the end surface of the cover is integrally connected with a concave plate.

[0009] By adopting the above technical solution, the arrangement of the concave plate makes it easy to take out the cover, and when the main runner is not needed, the cover can be used to cover the opening of the main runner.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] Pouring the valve cover upright can avoid the problems of the valve cover neck being easily loosened, the upper and lower wall thicknesses being uneven, and the inner hole becoming elliptical. The specific method is to let the molten steel enter the blind riser from the runner and then flow into the valve cover and the exposed riser, thereby ensuring that the sand blasting and neck of the casting will not shrink, the upper and lower wall thicknesses will not be uneven, and the inner hole will not become elliptical, so as to improve the quality of the casting. When moving is required, hold the handle to drive the sliding rod to move and then drive the placement plate to move. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] In the embodiment of the present utility model,

[0019] A flat bonnet casting system, such as Figures 1-4As shown, it includes a main runner 1, the main runner 1 is connected to a secondary runner 2, the secondary runner 2 is connected to a blind riser 3, the blind riser 3 is connected to a valve cover 4, an exposed riser 5 is provided above the valve cover 4, and also includes a placement plate 6 at the bottom, a sliding rod 7 is passed through the middle of the placement plate 6, and a handle 8 is integrally connected to one end of the sliding rod 7.

[0020] One end of the sliding rod 7 inside the placing plate 6 is integrally connected to the limiting plate 9, and a first sliding groove 10 for sliding the sliding rod 7 is provided inside the placing plate 6, and the placing plate 6 is provided with a second sliding groove 11 on one side of the first sliding groove 10 and connected to the first sliding groove 10, and a cross block 12 is integrally connected to the side of the sliding rod 7, and a spring 13 is provided on one side of the limiting plate 9, and the other end of the spring 13 is connected to the bottom of the second sliding groove 11.

[0021] A cover 14 is provided at the opening of the main runner 1 , and a concave plate 15 is integrally connected to the end surface of the cover 14 .

[0022] Working principle:

[0023] Pouring the valve cover 4 upright can avoid the problems of the valve cover 4 neck being easily loosened, the upper and lower wall thicknesses being uneven, and the inner hole becoming elliptical. The specific method is to allow the molten steel to enter the blind riser 3 from the runner and then flow into the valve cover 4 and the exposed riser 5, thereby ensuring that the sand blasting and neck of the casting will not shrink, the upper and lower wall thicknesses will not be uneven, and the inner hole will not become elliptical, thereby improving the quality of the casting. When it needs to be moved, hold the handle 8 to drive the sliding rod 7 to move and then drive the placement plate 6 to move.

[0024] After pulling the sliding rod 7, the limit plate 9 is driven to move outward and then the cross block 12 is driven to move. The movement of the cross block 12 will compress the spring 13. When no force is applied to the sliding rod 7, the sliding rod 7 returns to its original position under the action of the spring 13, reducing the occupied space. The setting of the limit plate 9 prevents the sliding rod 7 from separating from the placement plate 6.

[0025] The concave plate 15 is provided to facilitate taking out the cover 14 . When the main runner 1 is not needed, the cover 14 can be used to cover the opening of the main runner 1 .

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
