[0027] By arranging the opening and closing part 6 and the collecting cover 3, the opening and closing part 6 is arranged on both sides of the collecting box 2, the collecting cover 3 is split, and the opening and closing part 6 is connected with both sides of the collecting cover 3; when the collecting cover 3 needs to be opened, the driving part 8 drives the opening and closing part 6 to rotate outward, so that the opening and closing part 6 drives the collecting cover 3 to rotate and expand to both sides; since the opening and closing part 6 protrudes from the collecting box 2, the maximum expansion angle of the collecting cover 3 can reach 180 degrees, so that the upper space of the die casting machine can be completely released, and the purpose of replacing the track support is achieved; the track spacing does not affect the discharging and mold changing of the die casting machine; in addition, it needs to be further explained that the fixing mode of the support frame 1 in the above scheme includes but is not limited to bolt connection with the ground and direct placement on the ground by using counterweight.
[0028] The opening and closing part 6 comprises a bearing seat 601 arranged outside the collecting box 2, a rotating shaft 602 arranged in the bearing seat 601, a connecting frame 603 fixedly arranged on the rotating shaft 602 and fixedly connected with the collecting cover 3, and a swing rod 604 arranged below the rotating shaft 602 and connected with a connecting rod 605 connected with the driving part 8.
[0029] By arranging the connecting rod 605 and the swing rod 604, the swing rod 604 is fixedly arranged below the rotating shaft 602 and connected with the connecting rod 605; during work, the driving part 8 pulls the connecting rod 605 inward, the connecting rod 605 pulls the rotating shaft 602 to rotate through the swing rod 604, the rotating shaft 602 drives the collecting cover 3 to rotate and expand outward through the connecting frame 603, and the collecting cover 3 is horizontally split in this way, so that the problem of limited opening range caused by the traditional track support is avoided.
[0030] The driving part 8 comprises a fixed frame 801 arranged below the collecting box 2, a motor 804 arranged below the fixed frame 801, and a disc 802 arranged on the motor 804 and provided with a pin shaft 803 connected with the connecting rod 605.
[0031] Through setting the disc 802 and the pin shaft 803, the disc 802 can rotate at a constant speed under the driving of the motor 804, and the pin shaft 803 at the edge can drive the connecting rod 605 connected thereto to move in a circle, so as to drive the opening and closing component 6, and the opening and closing components 6 on both sides can be driven synchronously, thereby saving the cost of the driving device and ensuring the consistency of the opening and closing movement.
[0032] The position between the air guide pipe 12 and the discharge tooth plate 9 in the collecting box 2 is provided with a plurality of staggered air-cooled square pipes 7 which are communicated with the outside through the collecting box 2.
[0033] Through setting the air-cooled square pipe 7, the exhaust gas of the die casting machine is generated when the mold is opened after production, and has a high temperature. The air-cooled square pipe 7 is arranged through the collecting box 2, and the exhaust gas in the collecting box 2 is prolonged by the staggered arrangement. At the same time, the air-cooled square pipe 7 is arranged through the inside, so that the outside air can be communicated in the inside.

[0041] By arranging the activated carbon bin 507, the activated carbon bin 507 is filled with porous activated carbon, and the activated carbon can adsorb the peculiar smell in the air, so that the waste gas treatment of the die casting machine is more comprehensive.
[0042] Working principle: when the die casting machine opens the mold to generate waste gas, the fan 504 sucks out the air in the collecting box 2, so that the collecting box 2 generates negative pressure, and the waste gas is sucked in through the air guide pipe 12, the waste gas is lowered in temperature through the air-cooled square pipe 7 and contacts the discharge tooth plate 9, the discharge tooth plate 9 applies positive charge to the particles in the waste gas, so that the particles are adsorbed on the adsorption vertical plate 10, and then the waste gas is discharged after the peculiar smell is removed by the activated carbon bin 507;
[0043] When the die casting machine needs to replace the mold, the motor 804 drives the disc 802 to rotate, the disc 802 pulls the connecting rod 605 through the pin shaft 803, so that the connecting rod 605 drives the rotating shaft 602 to rotate through the swing rod 604, the rotating shaft 602 drives the collecting cover 3 to rotate outward through the connecting frame 603, so that the collecting cover 3 moves out of the range of the die casting machine, and the die casting machine is convenient to replace the mold.
[0044] The above is only a specific embodiment of the present application, but the technical features of the present application are not limited to this.
