[0025] As Figures 1 to 6 shown, the present invention provides a technical solution: a casting device for automotive metal fittings, including a connecting plate 1 and a protective frame 11 fixedly connected to the top, wherein the front of the protective frame 11 is open. The open protective frame 11 can ensure air circulation and at the same time facilitate the inspection of the cast automotive metal fittings; A support frame 12, arranged at the bottom end of the protective frame 11, is used for supporting and installing the lower die structure 2. The support frame 12 is connected to the protective frame 11 through an externally provided screw, so as to realize the stability of the lower die structure 2; The lower die structure 2, arranged at the top end of the support frame 12, is fixedly connected to the support frame 12; As Figures 1 to 6As shown, the upper mold structure 3 is arranged inside the top end of the protective frame 11 and is adapted to the lower mold structure 2 for filtering the waste gas during casting.

[0026] The lower mold structure 2 includes a mounting plate 20.

A plurality of cylinders 21 are equidistantly arranged at the bottom end of the mounting plate 20. The telescopic ends of the cylinders 21 penetrate through the top end of the mounting plate 20 and are fixedly connected to fixed rods. The mounting plate 20 is used for connecting the cylinders 21. And the cylinders 21 are located at the bottom end of the mounting plate 20 and can also protect the cylinders 21.

The support frame 12 is provided with a lower mold 22 at the top end. One side of the top end of the lower mold 22 is provided with a water inlet pipe 23. The other end of the water inlet pipe 23 penetrates through the outer wall of one side of the protective frame 11. A casting cavity 29 is opened at the top end of the lower mold 22. The water inlet pipe 23 is connected to an external water source. The water inlet pipe 23 continuously conveys cooling water to the cooling cavity 25 in the lower mold 22 and discharges it from the water outlet pipe 24, so as to form a circulating cooling source. The cooling cavity 25 is arranged around the lower mold 22. A condensing pipe 28 and a fixing plate 27 are arranged in the cooling cavity 25. The fixing plate 27 is used for supporting the condensing pipe 28. And one end of the lower mold 22 is provided with a water outlet pipe 24. The water outlet pipe 24 is communicated with the cooling cavity 25. The condensing pipe 28 arranged in the cooling cavity 25 is of an S-shaped structure, so as to cool the lower mold 22. The water inlet pipe 23 is connected to the water inlet of the condensing pipe 28, and the water outlet pipe 24 is connected to the water outlet of the condensing pipe 28, so as to form a cycle of condensed water.

[0027] An ejection hole is opened at the bottom end of the casting cavity 29. An ejector plate 26 is movably arranged in the ejection hole. The ejector plate 26 is connected to the fixed rod, and the ejector plate 26 is used for ejecting the cast metal fittings out of the casting cavity 29.

[0028] As Figures 1 to 6As shown in the figure, the upper die structure 3 includes a connecting pipe 34 and a second cylinder 31. The connecting pipe 34 is fixedly connected to the inner side of the top of the protective frame 11. An inlet pipe 33 is installed on the outer wall of one side of the connecting pipe 34. The other end of the inlet pipe 33 penetrates through the outer side of the top of the protective frame 11 and is fixedly connected to a feed hopper 32. A dust suction pipe 36 is connected to the outer wall of the other side of the connecting pipe 34. The other end of the dust suction pipe 36 penetrates through the outer side of the top of the protective frame 11 and is connected to a filter box 37. An adsorption plate 371 and a filter plate 372 are movably arranged between the inner walls of the filter box 37, and the adsorption plate 371 is located above the filter plate 372. A replacement door 373 is arranged on the outer side of the front of the filter box 37 through a hinge. A movable plate 39 is movably arranged in the inner wall of the connecting pipe 34. The telescopic end of the second cylinder 31 sequentially penetrates through the protective frame 11 and the inner side of the top of the connecting pipe 34 and is connected to the center of the top of the movable plate 39. A connecting rod 390 is arranged at the bottom end of the movable plate 39. The other end of the connecting rod 390 is provided with a telescopic pipe 35. The other end of the telescopic pipe 35 is connected to an upper die 30. A discharge pipe 38 is arranged at the center of the inner side of the top of the upper die 30. The discharge pipe 38 is communicated with the telescopic pipe 35, and the telescopic pipe 35 is located below the inlet pipe 33 and the dust suction pipe 36. The inlet pipe 33 and the feed hopper 32 are of an integrally formed structure. The inlet pipe 33 and the feed hopper 32 need to withstand the temperature of the molten metal of metal fittings at high temperature and will not cause the molten metal to pour into the feed hopper 32, resulting in damage to the feed hopper 32 and the inlet pipe 33. The molten metal enters the connecting pipe 34 through the inlet pipe 33 and flows into the lower die 22 through the discharge pipe 38 communicated with the upper die 30. Since waste gas is generated when the molten metal cools, the waste gas enters the filter box 37 through the dust suction pipe 36. Since the adsorption plate 371 and the filter plate 372 are arranged in the filter box 37, the waste gas generated when the molten metal cools can be absorbed, and the filtered waste gas is discharged again.

[0029] The working process of the present invention is as follows: First, the second cylinder 31 drives the movable plate 39 in the connecting pipe 34 to move downward. Since the bottom end of the movable plate 39 is fixedly connected to the connecting rod 390, and the connecting rod 390 is connected to the telescopic pipe 35, the telescopic pipe 35 can be driven to move downward. The telescopic pipe 35 is communicated with the discharge pipe 38, so that the upper mold 30 can be moved into the lower mold 22. Then, the molten metal flows into the connecting pipe 34 through the feed hopper 32 and the feed pipe 33. Since the telescopic pipe 35 and the discharge pipe 38 are communicated, the molten metal can enter the upper mold 30 and the lower mold 22, thereby realizing the casting of metal fittings. During the casting process, the coolant circulating in the condensing pipe 28 through the water inlet pipe 23 and the water outlet pipe 24 in the cooling cavity 25 can cool the high-temperature lower mold 22, so as to realize the rapid cooling of the metal fittings. And during the cooling process, waste gas will be generated. Since the lower mold 22 and the upper mold 30 are in a closed state, the generated waste gas will enter the filter box 37 through the dust suction pipe 36. The adsorption plate 371 and the filter plate 372 arranged in the filter box 37 can adsorb and filter the waste gas. Since the adsorption plate 371 and the filter plate 372 are prior arts, they will not be elaborated here. Then, the treated waste gas is discharged.

[0030] In summary, a casting device for automotive metal fittings includes a connecting plate 1 and a protective frame 11 fixedly connected to the top. The front of the protective frame 11 is open. The open protective frame 11 can ensure air circulation and is also convenient for viewing the cast automotive metal fittings. A support frame 12 is arranged at the bottom end of the protective frame 11 and is used for supporting and installing the lower mold structure 2. The support frame 12 is connected to the protective frame 11 through an external screw rod, so as to realize the stability of the lower mold structure 2. The lower mold structure 2 is arranged at the top end of the support frame 12 and is fixedly connected to the support frame 12. The upper mold structure 3 is arranged inside the top end of the protective frame 11 and is adapted to the lower mold structure 2 for filtering the waste gas generated during casting.

[0031] In this casting device for automotive metal fittings, in the lower mold structure 2, the mounting plate 20 and the cylinder 21 ensure good fixation of the casting during the casting process. The fixed rod penetrates into the telescopic end of the cylinder 21 to eject the formed casting. The lower mold 22 and the surrounding cooling cavity 25 and condensing pipe 28 effectively control the temperature of the casting and ensure the quality of the casting. The upper mold structure 3 drives the movable plate 39 and the telescopic pipe 35 to rise through the second cylinder 31, aligns the upper mold 30 and the lower mold 22, and realizes the sealing fit between the two.

[0032] At the same time, the feed pipe 33 and the dust suction pipe 36 are connected to the filter box 37 through the connecting pipe 34, ensuring that the waste gas generated during the casting process can be effectively filtered, ensuring that the waste gas during the casting process is fully treated, and avoiding harm to human health caused by the waste gas.
