Detailed Description

The present invention will be described in further detail with reference to the following embodiments and the accompanying drawings.

A vacuum slag collecting and exhausting system as shown in figure 2 comprises a left mold core 1 and a right mold core 2 which are oppositely arranged, wherein a product cavity 4 is arranged on the right mold core 2, and a vacuum slag collecting insert 3 is arranged on the left mold core 1. The vacuum slag collection insert 3 is provided with a slag ladle 5 communicated with the product cavity 4, a slag ladle buffer region 10 is arranged between the slag ladle 5 and the product cavity 6, and the slag ladle buffer region 10 is used for T-shaped slag ladle buffering.

The vacuum slag collection insert 3 is provided with a horizontal movable cavity 6 communicated with a slag ladle 5, a horizontally moving vacuum ejector rod 7 is arranged in the horizontal movable cavity 6, the front end of the vacuum ejector rod 7 can extend into the slag ladle 5, the rear end of the vacuum ejector rod 7 extends out of the vacuum slag collection insert 3 and is connected with a first oil cylinder 11, and a tail sealing structure 12 is arranged between the rear part of the vacuum ejector rod 7 and the vacuum slag collection insert 3. The front end of the vacuum ejector rod 7 is provided with a slag ladle barb 9 with a dovetail structure.

A gap is formed between the vacuum ejector rod 7 and the horizontal movable cavity 6, the end parts of the vacuum ejector rod 7 and the horizontal movable cavity 6 are provided with conical sealing surfaces, a vacuum channel 8 communicated with the horizontal movable cavity 6 is further arranged on the vacuum slag collecting insert 3, and the vacuum channel 8 is connected with a vacuum system of a die casting machine.

The vacuum slag collecting insert 3 is also provided with a compressed air inlet 13 communicated with the horizontal movable cavity 6 for blowing air into the horizontal movable cavity 6.

The lower part of the left mold core 1 is provided with a slag leakage hole 14, and the outer side end of the vacuum slag collection insert 3 is connected with a second oil cylinder 15 for pumping the front end of the vacuum slag collection insert 3 to the position above the slag leakage hole 14.

The implementation steps of the invention are as follows:

1. vacuumizing: when the die casting die is closed, the second oil cylinder 15 drives the whole vacuum slag collecting insert 3 and the die right die core 2 to be closed, the first oil cylinder 11 pushes the vacuum ejector rod 7 to the right side, the channel of the conical sealing surface is opened at the moment, a vacuum system of the die casting machine vacuumizes the horizontal movable cavity 6, the slag ladle 5 and the product cavity 4 through the vacuum channel 8, after the required vacuum degree is reached, the first oil cylinder 11 rapidly pulls the vacuum ejector rod 7 to the left side, the channel is closed through the conical sealing surface, and the deep cavity vacuumizing function of the column is reached.

2. Die casting production: the molten aluminum is firstly filled into a product high column, the product high column is filled from the bottom of the column to the top of the column along the high column, cold metal at the top of the column reaches the slag ladle 5 after being buffered by the T-shaped slag ladle, and all cold flow metal at the top of the column flows to the slag ladle to achieve the slag collecting function.

3. Opening the die: after the aluminum water is filled in the high column of the product, a slag ladle buffering exhaust and a slag ladle are formed at the top of the column. When the die is opened, the die casting machine ejects the product, the product high post moves to the right side, and the slag ladle 5 is broken at the slag ladle broken material oblique angle because the slag ladle at the die right die core 2 of the die has the slag ladle barb 9, and the slag ladle 5 is left in the die left die core 1, so that the product is normally discharged.

4. Ejecting a slag ladle: the second oil cylinder 15 drives the whole vacuum slag collecting insert 3 to move towards the left side, the slag ladle moves leftwards along with the insert under the actions of self-tightening force and a slag ladle barb 9, when the slag ladle moves to the position of a slag leakage hole 14, the vacuum ejection rod 7 ejects the slag ladle 5 outwards, compressed air is introduced into the insert through the compressed air inlet 13, the compressed air blows outwards through the conical sealing surface, and the slag ladle 5 falls off under the action of self gravity and the blowing of the compressed air, falls into the slag leakage hole 14 and is discharged out of the die. The compressed air can also blow the residual aluminum scraps, impurities and the like clean.

5. And (5) closing the die, folding the whole insert and the right die core, and repeating the actions. Therefore, the deep cavity bottom slag collecting and exhausting function is achieved, and the problems of forming and quality of the high pillars or the high blades on the product are solved.
