The first sub-runner 41 , the second sub-runner 42 , the third sub-runner 43 , the fourth sub-runner 44 , and the fifth sub-runner 45 are sequentially distributed and connected to one side of the instrument panel bracket die-casting area 20 . The first main runner 31 and the second main runner 32 are symmetrically distributed on both sides of the barrel 10 , and the length direction of the first main runner 31 and the second main runner 32 is parallel to the length direction of the side surface. The positions of the first main runner 31, the second main runner 32, the first sub-runner 41, the second sub-runner 42, the third sub-runner 43, the fourth sub-runner 44 and the fifth sub-runner 45 The distribution is determined according to the specific shape and structure of the car dashboard bracket, so that the liquid can be more evenly filled in each position of the die-casting area 20 of the dashboard bracket. That is to say, according to the specific shape and structure of the automobile instrument panel bracket, the utility model reasonably arranges the distribution of the main runners and sub-runners, so that the speed of the liquid passing through the gate is accelerated and the amount of liquid is reduced during die-casting. The amount entering the die-casting area 20 of the instrument panel bracket is sufficient, which slows down the rapid cooling of the liquid and improves the timeliness and integrity of the filling of the entire casting. Wherein, the symmetrical distribution of the first main runner 31 and the second main runner 32 prevents any difference in the molding of the automobile instrument panel bracket.

In this embodiment, the end of the first sub-runner 41 away from the first main runner 31 further includes two bifurcated runners 411 , and the two bifurcated runners 411 communicate with the die-casting area 20 of the instrument panel bracket.

There are many shrinkage cavities of different sizes in part of the thick wall of the casting. The pressurization device can be opened instantly by the trigger to pressurize. Under the action, the liquid is filled into the shrinkage cavity in the wall thickness of the casting and the entire mold wall. After high pressure and pressure holding, the casting without shrinkage cavity is more compact.

In this embodiment, the automobile instrument panel bracket is made of magnesium alloy, which is cast from magnesium alloy liquid.

The processing method of the automobile instrument panel support of the present utility model is carried out through the following steps:

Step 1: The liquid quickly passes through the barrel, and enters the die-casting area of the instrument panel bracket through the main runner and sub-runner for filling;

Step 2: The first liquid passes through the first main runner, and then fills through the first sub-runner, the second sub-runner, and the third sub-runner, and the second liquid passes through the second main runner, and then passes through the fourth sub-runner. The sub-runner and the fifth sub-runner are filled to the die-casting area of the instrument panel bracket;

Step 3: After the rapid filling is completed, although the casting is formed, there are many shrinkage cavities of different sizes in part of the thick wall. Within 10 milliseconds after the completion, the pressurization function is triggered, and at the same time the pressure chamber and the sprue are connected. The liquid that has not yet solidified at the gate, under the action of pressurization, fills the liquid into the shrinkage cavity in the wall thickness of the casting and the entire mold wall. After high pressure and pressure holding, the casting without shrinkage cavity is more dense.
