Description

Technical Field

[0001] This utility model relates to the field of casting production technology, specifically to an improved casting pouring mechanism. Background Technology

[0002] Castings are metal shaped objects obtained by various casting methods. They are objects with a certain shape, size and properties obtained by pouring, injecting, sucking or other casting methods into a pre-prepared mold after smelting liquid metal, cooling and then grinding.

[0003] In the casting production field, the pouring process plays a crucial role in casting quality and production efficiency. Currently, traditional casting pouring mechanisms have many problems in practical applications. For example, older processes typically use a main flow channel, resulting in a long filling distance and significant pressure loss during transmission to the product. This makes it difficult for pressure to effectively act on the casting, leading to defects such as voids and incomplete pouring. Furthermore, the long filling path not only increases process weight and production costs, but also often requires higher aluminum temperatures to ensure proper filling, resulting in energy waste.

[0004] Therefore, we propose an improved casting pouring mechanism. Utility Model Content

[0005] The main objective of this invention is to provide an improved casting pouring mechanism. The improved process eliminates the main channel in the old process, significantly shortening the filling distance and the distance from which the pressure is transmitted to the product. This allows the pressure to be transmitted to the die casting more efficiently and completely, effectively avoiding defects such as voids and insufficient pouring caused by excessive pressure loss. It significantly improves the forming quality and pass rate of the casting, ensuring the dimensional accuracy and performance stability of the casting, and effectively solving the problems in the background technology.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An improved casting pouring mechanism includes a die casting and a slurry cake. The die casting is located in a casting cavity, and the slurry cake is located in a material chamber. A secondary flow channel is provided between the material chamber and the casting cavity. An ingate is provided at one end of the secondary flow channel near the casting cavity. A first slag bag is provided at both ends of the casting cavity, and a branch flow channel and a second slag bag are provided at both ends of the slurry cake.

[0008] By adopting the above technical solutions, the improved new process eliminates the main channel in the old process, significantly shortening the filling distance and the distance of the pressure transfer to the product. This allows the pressure to be transferred to the die casting more efficiently and completely, effectively avoiding defects such as voids and insufficient pouring caused by excessive pressure loss, significantly improving the forming quality and pass rate of the casting, and ensuring the dimensional accuracy and performance stability of the casting.

[0009] Specifically, the casting cavity is provided with multiple equidistant third slag bags at the end away from the secondary flow channel.

[0010] Specifically, the secondary flow channel is provided in multiple sets, and the end of the secondary flow channel away from the casting cavity is connected to the branch flow channel.

[0011] Specifically, the diversion channel and the second slag bag are each provided in two sets, and the material chamber is connected to the second slag bag through the diversion channel.

[0012] Specifically, the first slag bag is arranged in four parallel groups, and the inner gate is arranged in multiple groups.

[0013] The beneficial effects of this utility model are:

[0014] The improved casting pouring mechanism described in this utility model firstly improves the quality of castings: the improved process eliminates the main channel in the old process, significantly shortening the filling distance and the distance of the pressure transfer to the product; this allows the pressure to be transferred to the die casting more efficiently and completely, effectively avoiding defects such as voids and insufficient pouring caused by excessive pressure loss, significantly improving the forming quality and pass rate of castings, and ensuring the dimensional accuracy and performance stability of castings;

[0015] Secondly, it reduces production costs: The shorter filling path significantly reduces the weight of the process, reducing the waste of metal raw materials and lowering raw material costs; at the same time, because the pressure transmission is smoother, it is not necessary to use a large amount of metal raw materials to make up for pressure loss in order to ensure the filling effect, as is the case with traditional processes, which further saves costs; in addition, the reduction in the weight of the process also means that the workload of subsequent processing and polishing is reduced, thus reducing labor costs and processing costs.

[0016] Third, energy saving: The improved casting mechanism can achieve good filling effect at a lower aluminum temperature. Compared with the traditional process that requires a higher aluminum temperature to ensure filling, the new process reduces the demand for heating energy, reduces energy consumption, conforms to the production concept of energy conservation and environmental protection, and reduces the company's energy costs and environmental impact;

[0017] Fourth, the casting process is optimized: the design of multiple secondary flow channels, inner gates, and a reasonably arranged slag pot makes the molten aluminum flow more evenly and stably during the casting process, and the impurities are collected more fully. The entire casting process is more scientific and efficient, which improves the controllability and stability of the production process and helps to improve the overall efficiency of casting production.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] As one embodiment of this utility model, such as Figures 1-2 As shown, the improved casting pouring mechanism of this utility model includes a die casting 1 and a slurry 6. The die casting 1 is located in the casting cavity 8, and the slurry 6 is located in the material chamber 9. A secondary flow channel 7 is provided between the material chamber 9 and the casting cavity 8. An inner gate 3 is provided at one end of the secondary flow channel 7 near the casting cavity 8. A first slag bag 2 is provided at both ends of the casting cavity 8, and a branch flow channel 4 and a second slag bag 5 are provided at both ends of the slurry 6.

[0024] In use, the metal raw material is first heated to a liquid state to make molten aluminum, which is then injected into the material chamber 9. The molten aluminum forms a cake 6 in the material chamber. At this time, the pouring process is started, and the molten aluminum begins to flow from the cake 6. It first flows into the branch channels 4 located at both ends of the cake 6. Since there are two sets of branch channels 4, the molten aluminum can be distributed more evenly. Then, the molten aluminum continues to flow through multiple sets of secondary channels 7. The end of the secondary channel 7 away from the casting cavity 8 is connected to the branch channel 4. The multiple sets of secondary channels 7 further disperse the molten aluminum, so that the molten aluminum can pass through the ingate 3 near the casting cavity 8 more evenly, and then fill the die casting 1 located in the casting cavity 8.

[0025] This utility model also includes a plurality of equidistant third slag bags at one end of the casting cavity 8 away from the secondary flow channel 7.

[0026] Slag Pocket: A slag pocket is a structure used to collect slag, gas, and other impurities generated during the casting process. During the pouring and filling of molten metal, impurities such as slag and gas are generated due to impurities in the raw materials, contamination during the smelting process, or air entrainment during the flow of molten metal. If these impurities are mixed into the casting, they will form defects such as porosity and inclusions, seriously affecting the quality and performance of the casting. The slag pocket, through reasonable placement and structural design, utilizes the characteristics of molten metal flow to guide slag, gas, and other impurities into it. When molten metal fills the mold, lighter slag and gas tend to flow towards the higher or lower parts of the mold. The slag pocket is placed in these locations, acting like an "impurity collection box," collecting slag, gas, etc., thereby ensuring a high purity of molten metal entering the casting, reducing casting defects, and improving the quality and yield of the casting. Combined with the improved casting pouring mechanism mentioned above, the multiple slag pockets comprehensively ensure the forming quality of the die casting.

[0027] Based on the location and function of the slag bags, they can be mainly classified into the following categories:

[0028] Top slag ladle: It is usually placed at the top of the mold. When molten metal fills the mold, gas and lighter slag will float upward. The top slag ladle can effectively capture these floating impurities and prevent them from remaining on the top of the casting and forming defects such as porosity and slag inclusions, thus ensuring the quality of the top of the casting. For example, in the production of some castings with more complex top structures and high surface quality requirements, the setting of the top slag ladle is particularly important.

[0029] Side slag bag: It is placed on the side of the mold. When molten metal flows into the mold from the side, or when there are areas on the side of the casting that are prone to eddies and gas accumulation, the side slag bag can collect the gas and slag carried by the eddies generated by the flow of molten metal, and prevent these impurities from affecting the forming quality of the side of the casting. For some box-type castings with complex side structures, the side slag bag can well ensure the smoothness of the side and the internal quality.

[0030] End slag bag: Located at the end of the casting filling process; as the molten metal gradually slows down when filling to the end, it is easy for gas and slag to accumulate. The end slag bag can collect these residual impurities to ensure the integrity and quality of the casting at the end. It is often used in the production of long strip-shaped castings with long process.

[0031] This utility model also includes that the secondary flow channel 7 is provided with multiple sets, and the end of the secondary flow channel 7 away from the casting cavity 8 is connected to the branch flow channel 4.

[0032] This utility model also includes that the diversion channel 4 and the second slag bag 5 are each provided with two sets, and the material chamber 9 is connected to the second slag bag 5 through the diversion channel 4.

[0033] This utility model also includes four sets of the first slag bag 2 arranged in parallel with each other, and multiple sets of the inner gate 3.

[0034] In use, this invention first heats the metal raw material to a liquid state to form molten aluminum, which is then injected into the material chamber 9. The molten aluminum forms a cake 6 in the material chamber, and then pouring begins. The molten aluminum flows from the cake 6, first flowing into the distribution channels 4 located at both ends of the cake 6. Since there are two sets of distribution channels 4, the molten aluminum can be distributed more evenly. Next, the molten aluminum continues to flow through multiple sets of secondary channels 7. The end of the secondary channels 7 away from the casting cavity 8 is connected to the distribution channels 4. The multiple sets of secondary channels 7 further disperse the molten aluminum, allowing it to pass more evenly through the ingate 3 near the casting cavity 8, and thus fill the die casting 1 located in the casting cavity 8. During the molten aluminum filling process, the first slag bag 2 set at both ends of the casting cavity 8, the multiple third slag bags equidistantly set at the end away from the secondary channels 7, and the second slag bag 5 at both ends of the cake 6 play an important role. These slag bags can effectively collect impurities such as slag and gas generated during the pouring process, preventing them from mixing into the die casting 1 and ensuring the purity and quality of the casting.
