Description

Technical Field

[0001] The utility model relates to a manufacturing technology for automobile parts, in particular to a manufacturing technology for automobile electric control box die castings. Background Art

[0002] The electric control box on electric vehicles is a carrier for installing and protecting the vehicle's electronic control equipment. Due to the requirements of lightweight vehicles and tightness of the electric control box, die casting is currently the most suitable method for manufacturing the electric control box. Figure 1 As shown, it has a square enclosure-like wall (marked: A), within which are designed various functional areas (not shown). The die-cast control box itself has two-way openings to facilitate the installation and placement of other electrical components. Once the interior of the control box is configured, panels are added to the circular edges of the two openings.

[0003] Because the walls of automotive electronic control boxes are relatively thin and the injection molding process is characterized by a high flow rate, the impact of the high-temperature, high-velocity melt can easily lead to poor ventilation and molding at the walls of the control box, resulting in poor molding quality. Therefore, special attention must be paid to the design of the channels for pouring, slag removal, and exhaust during die casting. Utility Model Content

[0004] In order to solve the problem of poor die-casting quality of automobile electronic control boxes, the utility model provides a pouring and slag discharge system for automobile electronic control boxes. The main technical solutions adopted are as follows:

[0005] A pouring system for die-casting of an electric control box, the key of which is: comprising a cavity of the electric control box, a pouring channel, a runner, an inner gate, and a slag cavity;

[0006] The electric control box cavity comprises four box wall forming areas, each of which is flat and connected end to end in a circular direction. The electric control box cavity has two annular edges.

[0007] Any of the box wall forming areas is a main pouring area, and a plurality of ingates are connected to the same annular edge corresponding to the main pouring area, and the ingates are curved, one end of the ingates is connected to the cavity of the electric control box, and the other end of the ingates is connected to the branch runner, and the branch runner is connected to the runner;

[0008] The box wall forming area arranged opposite to the main pouring area is the opposite pouring area, and the two annular edges corresponding to the opposite pouring area are respectively provided with the slag ladle cavity connected thereto.

[0009] On the one hand, the curved ingates can appropriately slow down the flow rate of the molten metal, avoiding the problem of poor exhaust caused by the high-speed impact of the molten metal on the cavity; on the other hand, the relative setting of the pouring position and the slag discharge position can better promote the exhaust of the cavity, thereby improving the molding quality of the die-casting.

[0016] The electric control box cavity 1 matches the outer shape of the electric control box. Other functional parts of the electric control box are also designed to be easy to demould. The following are adapted to the main structure of the electric control box:

[0017] The electric control box cavity 1 includes four box wall forming areas, which are flat-plate-shaped and connected end to end in a circular direction. The electric control box cavity 1 has two annular edges, which match the annular edges of the electric control box opening.

[0018] The four box wall forming areas include two longer box wall forming areas arranged opposite and in parallel and two shorter box wall forming areas arranged opposite and in parallel. The longer box wall forming areas and the shorter box wall forming areas are both rectangular plate-shaped structures. The length of the longer box wall forming area is greater than the length of the shorter box wall forming area. The width of the longer box wall forming area is equal to the width of the shorter box wall forming area. The longer box wall forming area and the shorter box wall forming area are perpendicular to each other, and the width side of the longer box wall forming area is connected to the width side of the shorter box wall forming area.

[0019] The four box wall forming areas are respectively defined as follows:

[0020] Any of the box wall forming areas is the main pouring and drainage area; preferably, a longer box wall forming area is used as the main pouring and drainage area;

[0021] The box wall forming area arranged opposite to the main pouring area is the opposite pouring area;

[0022] The box wall forming area adjacent to the main pouring area is a first lateral pouring area;

[0023] Another box wall forming area adjacent to the main pouring area is a second lateral pouring area;

[0024] The number of the pouring channel 2, the runner 3, the inner gate 4, and the slag cavity 5 is not unique;

[0025] Specifically:

[0026] A plurality of inner gates 4 are connected to the same annular edge corresponding to the main pouring area, and the plurality of inner gates 4 here are distributed along the length direction of the edge of the main pouring area; a plurality of slag cavities 5 are connected to another annular edge corresponding to the main pouring area, and the plurality of slag cavities 5 here are distributed along the length direction of the edge of the main pouring area.

[0027] A plurality of slag cavities 5 are respectively provided at the two annular edges corresponding to the opposite pouring and drainage area, and the slag cavities 5 are distributed along the length direction of the edge of the opposite pouring and drainage area.

[0028] The same annular edge corresponding to the first lateral pouring area is connected with multiple inner gates 4 and multiple slag cavities 5. The inner gates 4 here and the inner gates 4 of the main pouring area are located at the same annular edge. The inner gates 4 here are close to the main pouring area, and the slag cavities 5 here are close to the opposite pouring area; the other annular edge corresponding to the first lateral pouring area is connected with multiple slag cavities 5.

[0029] The same annular edge corresponding to the second lateral pouring area is connected with multiple inner gates 4 and multiple slag cavities 5. The inner gates 4 here and the inner gates 4 of the main pouring area are located at the same annular edge. The inner gates 4 here are close to the main pouring area, and the slag cavities 5 here are close to the opposite pouring area; the other annular edge corresponding to the second lateral pouring area is connected with multiple slag cavities 5.

[0030] The number of the ingates 4 corresponding to the second lateral pouring area is greater than the number of the ingates 4 corresponding to the first lateral pouring area.

[0031] Figure 3 The magenta dotted frame is the main outer contour of the electric control box cavity 1.

[0032] The ingate 4 is curved, with one end communicating with the control box cavity 1 and the other end communicating with the runner 3, which in turn communicates with the inlet runner 2. Both ends of the ingate 4 are bent 90 degrees. The length of the ingate 4, connected to the control box cavity 1, is 20-50 mm.

[0033] All the slag cavities 5 corresponding to the opposite pouring and draining areas are further connected to exhaust channels 6 .

[0034] The runner 2 comprises multiple runner sections connected in sequence, with the cross-sectional area of ​​the runner sections gradually decreasing along the flow direction. This gradually decreasing cross-sectional area of ​​the runner 2 can accelerate the flow of the molten metal. Each runner section matches one branch runner 3, and each branch runner 3 matches one ingates 4.

[0035] Beneficial effect: By adopting the technical solution of the utility model, the curved inner gate can appropriately slow down the flow rate of the molten liquid, avoiding the problem of poor exhaust caused by the high-speed impact of the molten liquid on the cavity; at the same time, the relative setting of the pouring position and the slag discharge position can better promote the exhaust of the cavity, thereby improving the molding quality of the die-casting.
