[0030] The following is in conjunction with the appendix Figures 1-6 The present invention will be described in further detail, but this is not intended to limit the scope of the present invention.

[0031] like Figure 1 and 2As shown in Figure 5, in one embodiment of this utility model, the cooling fan casting mold includes a first molding mechanism 100 and a second molding mechanism 200. The first molding mechanism 100 contains a first molding component 110. The first molding component 110 contains at least one molding arc block 115. The second molding mechanism 200 is movably disposed above the first molding component 110. The second molding mechanism 200 contains a second molding component 210. A molding cavity 111 is provided between the second molding component 210, the molding arc block 115, and the first molding component 110. The second molding component 210 contains a second injection channel for conveying injection material to the molding cavity 111 (not shown in the figure). The first molding component 110 contains a first injection channel for conveying injection material to the molding cavity 111 (not shown in the figure). Furthermore, the injection amount of each component is pre-calculated or specified (including possible losses).

[0032] The technical solution of this utility model uses a second molding mechanism to pull the second molding component toward the first molding component to form a sealed molding cavity; and under the limiting molding effect of the second molding component, the molding arc block and the first molding component, a cooling fan blade structure with high structural stability is formed; thereby improving the smoothness and stability of production and processing, and improving the casting efficiency.

[0033] Specifically, in some implementations, such as Figure 1 and 2 As shown, the second molding component 210 has a molding pressure plate 211 (detachable, for example, by snap-fit); the molding pressure plate 211 has at least one gating through hole 212; one end of the gating through hole 212 communicates with the second injection channel; the other end of the gating through hole 212 communicates with the molding cavity 111. That is, a molding processing area is defined on the second molding component 210, and a molding pressure plate 211 is added within this area; under the action of the molding pressure plate 211, its gating through hole 212, and the second injection channel, the distance between the outside and the molding processing area is increased, thus avoiding excessive interference from external factors to the interior; and it can improve the convenience of disassembly and maintenance and reduce maintenance costs. In some embodiments, such as... Figure 2 and 4As shown, the second molding component 210 has at least one limiting protrusion 213 on its surface facing the first molding component 110; the first molding component 110 has a limiting groove 112 corresponding to the limiting protrusion 213 on its surface facing the second molding component 210. This structure, through the repositioning effect of the limiting groove 112 and the limiting protrusion 213, can further improve the assembly precision, thereby forming a cooling fan blade structure with high structural stability; thus improving the smoothness and stability of the production process, and increasing the casting efficiency.

[0034] Specifically, in some implementations, such as Figure 1 and 4 As shown, the first molding component 110 has a molding groove 150 on its surface facing the second molding component 210; all molding arc blocks 115 are arranged around the inner wall of the molding groove 150. This structure ensures the assembly stability of all molding arc blocks 115 through the molding groove 150, and also helps to reduce the overall thickness of the first molding component 110, thereby improving space utilization. For example, Figure 4 As shown, the first molding component 110 is further provided with a mounting groove 113 on the side surface facing the second molding component 210; the mounting groove 113 is connected to the molding groove 150; and the mounting groove 113 is used to assemble the pipe for conveying the casting material.

[0035] Specifically, in some implementations, such as Figure 4 and 5 As shown, a forming protrusion 114 is also provided within the forming groove 150; an inner lining forming gap 117 is provided between the side of the forming arc block 115 away from the inner wall of the forming groove 150 and the forming protrusion 114; a blade forming gap 116 is provided between two adjacent forming arc blocks 115; and the blade forming gap 116 and the inner lining forming gap 117 are connected and configured to form the forming cavity 111. Wherein, as... Figure 5 As shown, each forming arc block 115 has a recessed portion 1151 and a protrusion 1152 on both sides of its surface; the blade forming gap 116 is formed between the recessed portion 1151 in one forming arc block 115 and the protrusion 1152 in the adjacent forming arc block 115. That is to say, this structure ensures the orderliness and stability of the forming process and improves the structural processing quality of the heat dissipation blades through various forming processes of the inner lining forming gap 117 and the blade forming gap 116.

[0036] Specifically, in some implementations, such as Figure 1 and 3As shown, the first molding mechanism further includes a first assembly plate 120, a second assembly plate 130, and a molding protrusion 140; the first assembly plate 120 and the second assembly plate 130 are arranged side by side; and the first molding component 110 is snapped into the interior of the first assembly plate 120; the molding protrusion 140 is connected to the side surface of the second assembly plate 130 facing the first molding component 110; and one end of the molding protrusion 140 is snapped into the side surface of the first molding component 110 away from the molding cavity 111 (the assembly groove in the groove). This structure forms a concave-convex assembly structure through the molding protrusion 140 and the assembly groove at the bottom of the first molding component 110; thereby improving the stability of its assembly and ensuring the ease of disassembly. In some embodiments, such as... Figure 3 and 6 As shown, a cylindrical protrusion 141 is provided on one side surface of the forming protrusion 140; at least one positioning cavity 143 is provided on the side surface of the cylindrical protrusion 141 facing the forming arc block 115; the bottom of the forming arc block 115 is engaged with the interior of the positioning cavity 143; and an assembly hole 142 is also provided in the middle of the inner part of the forming protrusion 140; the middle part of the bottom of the first forming component 110 is engaged with the assembly hole 142.

[0037] Specifically, in some implementations, such as Figure 1 As shown, the cooling fan casting mold also includes a first support component 300 and a second support component 400; a first molding mechanism 100 is connected to one side surface of the first support component 300; a second molding mechanism 200 is movably connected to one side surface of the second support component 400 facing the first support component 300; and the second support component 400 is connected to the first support component 300. In other words, the layered assembly of the first support component 300, the first molding mechanism 100, the second molding mechanism 200, and the second support component 400 ensures the orderly and stable extension and retraction of the second molding mechanism 200, thereby facilitating the formation of a cooling fan blade structure with high structural stability; further improving the smoothness and stability of production and processing, and increasing casting efficiency.

[0038] Specifically, in some implementations, such as Figure 1As shown, the second support component 400 has a mounting hole 401; a lifting drive component is provided within the mounting hole 401; the movable end of the lifting drive component passes through the mounting hole 401 and is drivenly connected to the second molding mechanism 200, causing the second molding mechanism 200 to reciprocate towards or away from the first molding mechanism 100. The lifting drive component can be a lifting drive cylinder or a lifting drive screw. In other words, the lifting drive action of the lifting drive component improves the compression sealing performance between the second molding mechanism 200 and the first molding component 110, thereby reducing the loss of casting material and facilitating the formation of a cooling fan blade structure with high structural stability; thus improving the smoothness and stability of the production process and increasing the casting efficiency.

[0039] Specifically, in some implementations, such as Figure 1 and 2 As shown, the second support component 400 has at least one positioning post 410 on its surface facing the first support component 300. The positioning post 410 passes through the second forming component 210 and the first forming component 110 (including the first assembly plate 120 and the second assembly plate 130) and is connected to the first support component 300. In other words, by positioning and restricting the vertical position of the second forming component 210 through the positioning post 410, excessive deviation during its movement is avoided, which is conducive to forming a cooling fan blade structure with high structural stability. Therefore, the smoothness and stability of the production process are improved, and the casting efficiency is increased.

[0040] Specifically, in some implementations, such as Figure 1 and 2 As shown, a limiting post 420 is provided on the side surface of the second support member 400 facing the first support member 300; a limiting block 430 is provided on the side end of the limiting post 420 away from the second support member 400; the limiting block 430 is connected to the first molding mechanism; and the second molding member 210 is sleeved on the outer surface of the limiting post 420. That is to say, by limiting the limiting block 430 at the extreme position at the bottom, excessive pushing is avoided to prevent impact damage between the second molding member 210 and the first molding member 110; thereby improving the safety of use.

[0041] Specifically, in some implementations, such as Figure 1 and 3As shown, the first support component 300 includes a buffer elastic element 310, a first support plate 320, and a second support plate 330; the first support plate 320 and the second support plate 330 are arranged side by side; and the first forming mechanism 100 is connected to the surface of the first support plate 320 away from the second support plate 330; the two ends of the buffer elastic element 310 are respectively connected to the first support plate 320 and the second support plate 330. There are four buffer elastic elements 310, arranged in an array; and a buffer spring is also included. This structure effectively reduces the external stress from the extrusion impact of the second forming mechanism 200 through a three-layer compression buffering effect, thereby improving safety during use.
