Description

Technical Field

[0001] It relates to the field of aluminum alloy die casting, and particularly to a material guiding pipe of a die casting machine that can be cooled down. Background Art

[0002] The aluminum alloy material guiding pipe of a die casting machine is made of high-temperature resistant alloy steel, with a thick diameter and a long length, resulting in high manufacturing costs, and it is a vulnerable part on the aluminum alloy die casting machine.

[0003] The main reason for the scrapping of the material guiding pipe is the ablation at the bottom of the pouring port of the material guiding pipe. When die casting, aluminum alloy liquid at a high temperature of more than 650 °C is poured into the inlet of the material guiding pipe, the temperature at the bottom of the inlet of the material guiding pipe rises, and the temperature of the material guiding pipe accumulates continuously during long-term operation. The temperature of the material guiding pipe remains at a high temperature of up to 650 °C for a long time. The working temperature allowed by many heat-resistant alloy steels does not exceed 650 °C. Coupled with the long-term scouring effect of high-temperature aluminum alloy, the material guiding pipe will show serious ablation. The ablated material guiding pipe seriously affects the die casting speed of the press head, resulting in defects such as many pores and inclusions in the die-cast products.

[0004] During use, the front end of the material guiding pipe of the die casting machine is assembled with the die hole, and the material guiding pipe passes through the moving die of the die casting machine and extends outside, facilitating the pouring of molten aluminum into the inlet of the material guiding pipe. The pushing plunger quickly pushes the high-temperature molten aluminum into the die. If the material guiding pipe is severely ablated and causes dimensional changes, the pushing plunger cannot quickly press the aluminum into the die, resulting in problems such as pores, shrinkage porosity, and skinning.

[0005] Therefore, it is necessary to develop a material guiding pipe of a die casting machine that can be cooled down to solve the above problems. Content of the Utility Model

[0006] The purpose of the present utility model is to provide a material guiding pipe of a die casting machine that can be cooled down.

[0009] A cooling component, including a ring body surrounding the outside of the material guiding pipe. The ring body has a docking groove formed by inward depression from the inner surface and a cooling channel penetrating the ring body. The heat conducting part extends into the docking groove, and the cooling channel is adjacent to the heat conducting part.

[0010] Further, the cooling channel includes a first cooling channel, and the first cooling channel is located between adjacent docking grooves and is close to the inner side of the ring body.

[0011] Further, the first cooling channel vertically penetrates from the upper surface of the ring body to its lower surface, and the top of the first cooling channel is the liquid inlet, and its bottom forms the liquid outlet.

[0012] Further, the cooling channel includes a second cooling channel, which is formed by inward depression from the inner wall of the docking groove.

[0013] Further, one end of the second cooling channel penetrates through the ring body and communicates with the top of the first cooling channel, and the other end bends along the inner wall of the docking groove to its bottom and penetrates through the ring body to communicate with the bottom of the first cooling channel.

[0014] Further, the second cooling channel is attached to the surface of the heat conduction part.

[0015] Further, the material guiding pipe has a pouring port, and the ring body is installed on one side of the pouring port, semi - surrounds the material guiding pipe, and exposes the pouring port.

[0016] Further, a fastener is installed on the end face of the ring body, the fastener surrounds the other side of the pouring port, semi - surrounds the material guiding pipe, and its two ends are fixedly connected to the ring body.

[0017] Further, the number of the temperature - reducing components is a pair. One temperature - reducing component is located on one side of the pouring port, and the other temperature - reducing component is installed below the pouring port.

[0018] Further, an annular temperature - reducing component is installed around the material guiding pipe, the annular temperature - reducing component wraps the material guiding pipe, and its structure is the same as that of the temperature - reducing component.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] The present utility model relates to a heat - coolable die - casting machine material guiding pipe, which includes a material guiding pipe 1 and a cooling component 2 sleeved on the material guiding pipe 1.

[0029] The material guiding pipe 1 passes through the moving die of the die - casting machine and extends outside, facilitating the pouring of molten aluminum into the inlet of the material guiding pipe 1. The pushing plunger quickly pushes the high - temperature molten aluminum into the mold. It includes a pipe body 11 and a liquid guiding channel 12 penetrating the pipe body 11. The pipe body 11 is made of high - temperature resistant alloy steel, and its length can be changed according to requirements.

[0030] Preferably, the pipe body 11 has a number of heat - conducting parts 14. The heat - conducting parts 14 extend outward from the outer surface of the pipe body 11. In this embodiment, the heat - conducting parts 14 are trapezoidal and are arranged equidistantly around the pipe body 11. The heat - conducting parts 14 are used to conduct the temperature brought by the molten aluminum passing through the liquid guiding channel 12.

[0031] The cooling component 2 includes a ring body 21 and a docking groove 22 formed by a depression on the inner surface of the ring body 21. The ring body 21 surrounds the pipe body 11, and the heat conduction part 14 extends into the docking groove 22.

Preferably, the ring body 21 is installed on one side of the pouring port 13, semi-surrounds the pipe body 11, exposes the pouring port 13, and a fastener 23 is installed on its end face. The fastener 23 surrounds the other side of the pouring port 13, semi-surrounds the pipe body 11, and its two ends are fixedly connected to the ring body 21. The ring body 21 and the fastener 23 cooperate to lock outside the pipe body 11.

[0032] The cooling component 2 is also provided with a cooling channel 20. The cooling channel 20 includes a first cooling channel 24 and a second cooling channel 25. The first cooling channel 24 is located between adjacent docking grooves 22, and is close to the inner side of the ring body 21. The first cooling channel 24 vertically penetrates from the upper surface of the ring body 21 to its lower surface. The top of the first cooling channel 24 is a liquid inlet, and the liquid inlet is connected to a pipe 4. The bottom of the first cooling channel 24 forms a liquid outlet, and the liquid outlet is connected to a pipe 4.

The second cooling channel 25 is in contact with the surface of the heat conduction part 14. The coolant enters the first cooling channel 24 and the second cooling channel 25 through the pipe 4 and the liquid inlet, and then is discharged through the pipe 4 and the liquid outlet. Preferably, the coolant discharged through the pipe 4 and the liquid outlet flows back and then enters the pipe 4 and the liquid inlet to form a cycle. Further, the pipes 4 connected to the liquid inlet can be interconnected, and the pipes 4 connected to the liquid outlet can be interconnected.

Similarly, a heat conducting part 14 is provided in the corresponding area of the material guiding pipe 1. The heat conducting part 14 extends outward from the outer surface of the material guiding pipe 1 and extends into the annular cooling component 3.

[0036] When the material guiding pipe of the die-casting machine capable of cooling according to the present utility model is installed, the material guiding pipe 1 passes through the moving die of the die-casting machine and extends outwards, which is convenient for pouring molten aluminum into the material guiding pipe 1. Different numbers of cooling components 2 can be selected for installation according to requirements. The heat conducting part 14 on the outer surface of the cooling component 2 extends into the docking groove 22, and then is locked outside the pipe body 11 through the cooperation of the ring body 21 and the fastener 23. During use, the molten aluminum enters the liquid guiding channel 12 through the pouring port 13.
