Abstract
Description
Technical Field
[0001] This utility model relates to the field of die casting technology, and in particular to a die casting mold flow channel structure with strong corrosion resistance. Background Technology
[0002] Die casting molds are the core equipment in die casting production. They are used to force molten metal into the forming cavity of the mold under high pressure and high speed. After the metal cools and solidifies, a casting is obtained. They are widely used in the manufacturing of parts for automobiles, home appliances, and 3C products. However, existing die casting molds have obvious defects: First, the runner layout is simple, mostly a main runner, a single branch runner, and a single gate structure. The molten metal experiences large pressure loss and uneven flow velocity during flow, resulting in insufficient filling of the corners or complex areas of the forming cavity, making it difficult to die cast a full product. Second, there is a lack of a complete impurity filtration and cold material collection structure. Slag and cold material mixed in with the molten metal directly impact the mold core at high speed, causing severe corrosion of the mold core. This not only shortens the service life of the mold but also causes defects such as pitting and scratches on the surface of the casting, affecting product quality. Utility Model Content

A second flow channel is provided on one side of the first flow channel, and one end of the second flow channel is connected to a second gate, which is connected to the molding cavity. Both sides of the first branch runners are provided with second branch runners, which are connected to the main runner.

[0017] Please see the appendix Figure 1 -Appendix Figure 3This utility model provides an embodiment of a die-casting mold runner structure with strong corrosion resistance, including a gating system 1 and a molding cavity 2. One end of the gating system 1 is connected to a main runner 11, and both sides of the main runner 11 are connected to first branch runners 14. Both sides of the first branch runners 14 are connected to first runners 15, one end of the first runners 15 is connected to a first gate 16, and the first gate 16 is connected to the molding cavity 2. A second runner 17 is provided on one side of the first runner 15, and one end of the second runner 17 is connected to a second gate 18, which is connected to the molding cavity 2. Second runners 19 are provided on both sides of runner 14, and the second runners 19 are connected to the main runner 11. One end of the second runner 19 is connected to a third runner 110, and one end of the third runner 110 is connected to a third gate 111, which is connected to the molding cavity 2. A fourth runner 114 is provided on one side of the third runner 110, and one end of the fourth runner 114 is connected to a fourth gate 115, which is connected to the molding cavity 2. The gating system 1 and the main runner 11 are channels for molten metal to enter. The first runner 14 and the second runner 19 are connected to the main runner 111. 9 is the primary runner. The first runner 15, the second runner 17, the third runner 110, and the fourth runner 114 are secondary runners. The first gate 16, the second gate 18, the third gate 111, and the fourth gate 115 are used to connect the secondary runners and the forming cavity 2. The forming cavity 2 is used for product forming. One end of the main runner 11 is connected to the first slag pot 12, the other end of the third runner 110 is connected to the second slag pot 112, and the other end of the fourth runner 114 is connected to the second slag pot 112. The first slag pot 12 and the second slag pot 112 are used to filter molten slag. The first slag pot 12 is connected to... There is a first water inlet 13, and a second water inlet 113 is connected to the second slag bag 112. The first water inlet 13 and the second water inlet 113 are used for venting and discharging residual material. A fifth water inlet 116 is connected to the fourth flow channel 114. The fifth flow channel 116 is used for venting and discharging residual material. A third water inlet 117 is connected to the fifth flow channel 116. The third water inlet 117 is used for venting and discharging residual material. Cold material wells 118 are connected to the main flow channel 11, the first branch channel 14, the first flow channel 15, the third flow channel 110, the fourth flow channel 114 and the fifth flow channel 116. The cold material wells 118 are used for collecting cold material.
[0018] Working Principle: When using this invention, molten metal first enters the mold through the gating system 1, then flows into the main channel 11. The first slag trap 12, connected at one end of the main channel 11, can initially filter slag impurities in the molten metal. The first gate 13 assists in discharging gas and excess molten metal from the main channel 11. Simultaneously, the cold slug well 118 on the main channel 11 collects the cold slug at the front of the molten metal, preventing it from affecting the casting quality. The molten metal in the main channel 11 is then diverted to the first branch channel 14 and the second branch channel 19. The cold slug well 118 on the first branch channel 14 further collects the cold slug before the molten metal enters the first flow channel 15 and the second flow channel 17 on both sides. The first flow channel 15 delivers molten metal to the forming cavity 2 through the first gate 16, while the second flow channel 17 supplements the supply to the forming cavity 2 through the second gate 18. The cold slug well 118 on the first flow channel 15 can intercept the cold material in the path; the second branch flow channel 19 delivers molten metal to the third flow channel 110. One end of the third flow channel 110 supplies material to the forming cavity 2 through the third gate 111, and the other end is connected to the second slag pot 112 to filter the remaining slag. The second gate 113 on the second slag pot 112 assists in venting and discharging residual material, and the cold slug well 118 on the third flow channel 110 collects the cold material; at the same time, the fourth flow channel 114 on one side of the third flow channel 110 supplies material to the forming cavity 2 through the fourth gate 115. The fourth flow channel 114 is also connected to the fifth flow channel 116. The third gate 117 on the fifth flow channel 116 further assists in venting and discharging residual material, and the cold slug wells 118 on the fourth flow channel 114 and the fifth flow channel 116 can both intercept the cold material in the corresponding path.
