Description

Technical Field

[0001] This utility model relates to the field of liquid metal anti-overflow die casting mold technology, and in particular to a liquid metal anti-overflow die casting mold. Background Technology

[0002] Die casting molds are tools used to cast metal parts, specifically for completing the die casting process on a specialized die casting and forging machine. The basic die casting process involves molten metal being poured into the mold cavity at low or high speed. The mold has movable cavity surfaces, which are pressurized and forged as the molten metal cools, eliminating shrinkage cavities and porosity defects in the blank and achieving a forged, fragmented grain structure within the blank.

[0003] In the existing technology, existing die-casting molds on the market generally have gaps between the fixed mold and the moving mold when the mold is closed, which makes it easy for material to overflow during the mold closing process, affecting the processing effect of the mold and making it difficult to meet the processing needs. Therefore, a liquid metal anti-overflow die-casting mold is proposed to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is that existing die-casting molds on the market generally have gaps between the fixed mold and the moving mold when the mold is closed, which makes it easy for material to overflow during the mold closing process, affecting the processing effect of the mold and making it difficult to meet the processing needs.

[0005] To solve the above-mentioned technical problems, the present invention provides a liquid metal anti-overflow die casting mold, including a fixed mold base, a fixed mold body fixedly connected to the top of the fixed mold base, a forming groove opened on the top of the fixed mold body, a plurality of support columns fixedly connected around the top of the fixed mold base, a top plate fixedly connected to the top of the plurality of support columns, a cylinder fixedly installed at the top of the top plate, a moving mold base fixedly connected to the output end of the cylinder extending through to the bottom of the top plate, a moving mold body fixedly connected to the bottom of the moving mold base, a pressure block fixedly connected to the bottom of the moving mold body, and the pressure block matching the forming groove.

[0006] Two anti-overflow clamping blocks are slidably connected to the top of the fixed mold base. The two anti-overflow clamping blocks are located on both sides of the fixed mold body and the moving mold body, and the inner diameter of the two anti-overflow clamping blocks is the same as the outer diameter of the fixed mold body and the moving mold body. A driving component for driving the two anti-overflow clamping blocks to slide is provided at the bottom of the fixed mold base.

[0007] Preferably, the drive assembly includes two sliding plates, each located below two anti-overflow clamping blocks and slidably connected to the bottom of the fixed mold base. Two connecting rods are rotatably connected to the bottom of the two sliding plates. A connecting plate is rotatably connected to the bottom of the fixed mold base, positioned between the two sliding plates. One end of each connecting rod is rotatably connected to both ends of the connecting plate. Two strip-shaped grooves are formed through the top of the fixed mold base. Two sliding pillars are slidably connected inside the two strip-shaped grooves. The top ends of the two sliding pillars extend through to the top of the fixed mold base and are fixedly connected to the bottom of the two anti-overflow clamping blocks, respectively. The bottom ends of the two sliding pillars extend through to the bottom of the fixed mold base and are fixedly connected to the top of the two sliding plates. When one sliding plate moves, the other sliding plate moves under the influence of the connecting plate and the two connecting rods. The two sliding plates can then drive the two anti-overflow clamping blocks to move in opposite or relative directions on the top of the fixed mold base, thereby clamping the fixed mold body and the exterior of the moving mold body.

[0008] Preferably, an electric push rod is fixedly installed at the bottom of the fixed mold base and on one side of one of the slide plates. The output end of the electric push rod is fixedly connected to one side of the surface of one of the slide plates. The electric push rod can push one of the slide plates.

[0010] Preferably, limiting grooves are respectively opened on one side of the opposing surfaces of the plurality of support columns, and limiting sliders are respectively fixedly connected to both sides of the surface of the moving mold base. The outer surface of the limiting slider is slidably installed to the inner sidewall of the corresponding limiting groove, which can make the moving mold base more stable when sliding up and down.

[0011] Preferably, the bottom of the fixed mold base is fixedly connected with multiple legs for support.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention utilizes components such as a sliding plate, connecting rods, a connecting plate, and anti-overflow clamping blocks. An electric push rod drives one of the sliding plates to move, while the other sliding plate moves under the influence of the connecting plate and two connecting rods. These two sliding plates then move two anti-overflow clamping blocks on the top of the fixed mold base in opposite or relative directions, thereby clamping the fixed mold body and the moving mold body. Compared with existing technologies, the sealing gasket on the inner wall of the anti-overflow clamping block can seal the gaps that exist when the fixed mold body and the moving mold body are closed, preventing material overflow.

[0020] Two anti-overflow clamping blocks 10 are slidably connected to the top of the fixed mold base 1. The two anti-overflow clamping blocks 10 are located on both sides of the fixed mold body 2 and the moving mold body 8, and the inner diameter of the two anti-overflow clamping blocks 10 is the same as the outer diameter of the fixed mold body 2 and the moving mold body 8. A drive assembly for driving the two anti-overflow clamping blocks 10 to slide is provided at the bottom of the fixed mold base 1.

[0021] like Figure 3As shown, the drive assembly includes two slide plates 11, which are located below the two anti-overflow clamping blocks 10 and slidably connected to the bottom of the fixed mold base 1. Two connecting rods 12 are rotatably connected to the bottom of the two slide plates 11. A connecting plate 13 is rotatably connected to the bottom of the fixed mold base 1 and located between the two slide plates 11. One end of each of the two connecting rods 12 is rotatably connected to both ends of the connecting plate 13. Two strip grooves 14 are formed through the top of the fixed mold base 1. Two sliding pillars 15 are slidably connected inside the two strip grooves 14. The top ends of the two sliding pillars 15 extend through to the top of the fixed mold base 1 and are fixedly connected to the bottom of the two anti-overflow clamping blocks 10, respectively. The bottom ends of the two sliding pillars 15 extend through to the bottom of the fixed mold base 1 and are fixedly connected to the top of the two slide plates 11, respectively. One of the slide plates 11 moves, and the other slide plate 11 moves under the drive of the connecting plate 13 and the two connecting rods 12. The two slide plates 11 can drive the two anti-overflow clamping blocks 10 to move in opposite or relative directions on the top of the fixed mold base 1 to clamp the outside of the fixed mold body 2 and the moving mold body 8.

[0022] like Figures 1 to 3 As shown, multiple support legs 18 are fixedly connected around the bottom of the fixed mold base 1 for support. Limiting grooves 17 are respectively opened on one side of the opposite surface of the multiple support columns 4.
