Technical Field
[0001] The utility model relates to the technical field of gating systems, in particular to a flowing adsorption type gating system structure. Background Art
[0002] A hub, as a component mounted on a relevant shaft at the center, is directly connected to important components such as bearings, bears a relatively large load, and also bears frictional force. Therefore, it is required that the casting has a dense structure, high hardness and wear resistance, and good comprehensive mechanical properties.
[0003] In the existing process, impurities and other dirt will be adsorbed on the mold wall during the flowing process, finally avoiding hole defects such as sand holes and slag holes, thus causing a decline in product quality. At the same time, due to its small structure, it is not applicable to filters.
[0004] Therefore, it is necessary to design a flowing adsorption type gating system structure to solve the above problems. Content of the Utility Model
[0005] The purpose of the utility model is to provide a flowing adsorption type gating system structure to overcome the above-mentioned deficiencies existing in the current prior art.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A flowing adsorption type gating system structure, which includes a mold body and a gating system placed in the mold body. The gating system includes a pouring cup, a transverse flow path connected to the bottom end of the pouring cup, several groups of filtering buffer sheets arranged on the transverse flow path, and several groups of longitudinal flow paths respectively connected to the filtering buffer sheets. It is characterized in that: the filtering buffer sheets are bent at a 90° angle, the longitudinal flow path includes a first-end flow path connected to the filtering buffer sheet, several flow paths, and a buckle overlapping between the flow paths. The first-end flow path, the flow paths and the buckle are connected in series in a positive and negative overlapping manner. A riser is opened on each group of flow paths, and a casting groove is overlapped with the riser.
[0008] Preferably, the transverse flow path and the longitudinal flow path are perpendicular to each other.
[0009] Preferably, the filtering buffer sheets are evenly distributed on the transverse flow path.
[0010] Preferably, the first-end flow path 1 and the buckle are on one side, and the other flow paths are on the other side, thus forming an alternating upper and lower surface.
[0011] Preferably, both the riser and the casting groove are of a flanged structure, and the overlapping distance between the two is 1.5 mm.
[0012] The beneficial effects of the present utility model are as follows: Through the positive and negative overlapping method between the buckle and the flow channel, and by setting a 90-degree angle filtering buffer sheet, the molten iron can be automatically filtered and purified during the flowing process without using measures such as filter screens, preventing impurities, dirt, etc. from entering the cavity, enabling the molten iron to enter the cavity calmly and slowly without causing any appearance defects such as holes, sand holes, slag holes, etc.; at the same time, it ensures that the flow path directly climbs over the riser, saving space and providing sufficient heat for the riser, ensuring that the riser can effectively compensate for the casting, thereby avoiding internal defects such as shrinkage porosity, and finally obtaining a highly dense casting with uniform structure and performance.

[0019] Refer to Figures 1-3, a structure of a flowing adsorption casting system, which includes a mold body and a casting system placed inside the mold body. The casting system includes a pouring cup 1, a transverse flow path 2 connected to the bottom end of the pouring cup, several groups of filtering and buffering sheets 3 arranged on the transverse flow path, and several groups of longitudinal flow paths 4 respectively connected to the filtering and buffering sheets;
[0020] The transverse flow path 2 and the longitudinal flow path are arranged perpendicular to each other; this ensures the maximum utilization of the space of the entire mold;
[0021] The filtering and buffering sheets are evenly distributed on the transverse flow path 2;
[0022] The filtering and buffering sheets are bent at a 90° angle, thereby reducing the kinetic energy of the molten iron when it falls and preventing the molten iron from washing away the mold wall.
[0023] The longitudinal flow path 4 includes a first-end flow path 41 connected to the filtering and buffering sheet 3, several flow paths 42, and a buckle 43 lapped between the flow paths. The first-end flow path 41, the flow paths 42, and the buckle 43 are connected in series in a positive and negative lapping manner. The first-end flow path 41 and the buckle 42 are on one side, and the flow paths 42 are on the other side, forming an up-and-down stagger. Specifically, the first-end flow path 41 is at the first end, the end is connected to the first flow path, and the top surface of the end of the first-end flow path 41 is in contact with the bottom surface of the first end of the first flow path. The end of the first flow path is connected to a first buckle, and the bottom surface of the end of the first flow path is in contact with the top surface of the first end of the first buckle. The end of the first buckle is connected to the second flow path, and the top surface of the end of the first buckle is in contact with the bottom surface of the first end of the second flow path. The end of the second flow path is connected to a second buckle, and the bottom surface of the end of the second flow path is in contact with the top surface of the first end of the second buckle, and so on, repeating the connection in sequence to form a positive and negative lap; this structure ensures that during the entire flow process of the molten iron, impurities and dirt can be adsorbed by the cavity wall and do not enter the cavity; in addition, the lapping area in the upper part is 1.5 times that of the lower part;
[0024] A riser 44 is opened on each group of flow paths. All the flow paths 42 need to climb over the riser 44. This not only occupies less space but also can arrange more castings while ensuring the heat of the riser, ensuring both production efficiency and the quality of the castings, and there will be no internal shrinkage, etc.;
[0025] The riser 44 is lapped with a casting groove 5, and both the riser 44 and the casting groove 5 are of a flanged structure, and the lapping distance between the two is 1.5 mm.
[0026] In this embodiment, the entire gating system is a pressurized gating system to ensure the directional flow of molten iron. Three groups of filtering buffer plates 3 are provided and evenly distributed on the transverse flow path. Each group of filtering buffer plates 3 is connected to a longitudinal flow path 4. Casting grooves 5 are provided on both the left and right sides of the longitudinal flow path 4 on both sides, and a casting groove 5 is provided on one side of the middle longitudinal flow path 4. Each longitudinal flow path 4 is specifically configured as follows: the first-end flow path 41 is placed at the first end and is connected to the first flow path at the end. The top surface of the end of the first-end flow path 41 is connected to the bottom surface of the first end of the first flow path 45. A buckle 43 is connected to the end of the first flow path 45.

The bottom surface of the end of the second flow path 47 is connected to the top surface of the first end of the second buckle 47. The end of the second buckle 47 is connected to the third flow path 48. The top surface of the end of the second buckle 47 is connected to the bottom surface of the first end of the third flow path 48 (the specific length is determined according to the size of the mold. Just follow the above cycle, and the number of longitudinal flow paths provided is also determined according to the specific size of the mold, and flow paths can be added).
[0027] The beneficial effects of the present utility model are as follows: Through the way of positive and negative lapping between the buckle and the runner, and by setting the 90-degree angle filtering buffer plate, without using measures such as filter screens, during the flow of molten iron, the molten iron can be automatically filtered and purified, preventing impurities, dirt, etc. from entering the cavity, enabling the molten iron to enter the cavity calmly and slowly without causing any external defects such as holes, sand holes, slag holes, etc.; at the same time, it ensures that the runner directly climbs over the riser, saving space and providing sufficient heat for the riser, ensuring that the riser can effectively compensate for the casting, thereby avoiding internal defects such as shrinkage porosity, and finally obtaining high-density castings with uniform structure and performance.
