Description

Technical Field

[0001] This invention relates to the field of die casting technology, and in particular to a feed structure that prevents barrel erosion and improves service life. Background Technology

[0002] In conventional die-casting molds, molten aluminum is scooped from the melting furnace by a crucible ladle and poured into a material tank through the inlet. The main problem is that long-term pouring of molten aluminum can cause impact pits to form below the material tank inlet, resulting in the accumulation of cold molten aluminum material. This leads to frequent repairs of this structure, affecting the production cost of the mold, and also results in a short structural lifespan, impacting mass production. To solve these problems, the structure needs to be improved. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a feeding structure that prevents barrel erosion and improves service life, which has the characteristics of avoiding erosion, improving production costs, and increasing the service life of the structure.

[0004] The technical solution adopted by the present invention to solve its technical problem is: to provide a feeding structure to prevent barrel erosion and improve service life, including a mold frame, a die-casting mold and a hydraulic cylinder mounting frame. The die-casting mold is installed in the mold frame. A barrel for inserting into the die-casting mold is installed on one side of the mold frame. A feeding port is provided on the upper side of the barrel. A hydraulic cylinder mounting frame corresponding to the barrel is installed on one side of the mold frame. A lifting hydraulic cylinder with its main shaft facing downward is installed on the hydraulic cylinder mounting frame. A connecting rod extending downward is installed on the main shaft of the lifting hydraulic cylinder. A feeding funnel is installed on the lower end of the connecting rod. The lower end of the feeding funnel is aligned with the feeding port.

[0005] In this technical solution, a hydraulic cylinder mounting bracket is installed to facilitate the installation of the lifting hydraulic cylinder. By installing a connecting rod on the lifting hydraulic cylinder, it is ensured that the connecting rod can move the feed funnel up and down. By inserting the feed funnel into the feed inlet, the molten aluminum can enter along the feed funnel without impacting the inside of the barrel, thus avoiding erosion.

[0006] As a supplement to this technical solution, the lower end of the connecting rod is bent toward the feed hopper, and the bent end of the connecting rod is inserted into the feed hopper and welded to fix it. By inserting the connecting rod into the feed hopper, the connection strength between the two is enhanced, and the welding fixation further improves the docking strength.

[0007] As a supplement to this technical solution, the feed hopper includes a hopper body, a curved channel, and a discharge end. The hopper body is a cone shape with a larger upper part and a smaller lower part. A curved channel is provided at the lower end of the hopper body. The lower end of the curved channel is curved towards the die-casting mold. A discharge end is provided at the lower end of the curved channel.

[0008] In this technical solution, a curved channel is set to reduce the impact force of the molten aluminum, and a discharge end is set to ensure that the molten aluminum can be discharged smoothly, avoiding direct impact of the molten aluminum into the barrel, thus protecting the barrel structure.

[0009] As a supplement to this technical solution, the discharge end is provided with an elliptical injection port arranged in a horizontal direction. By providing an elliptical injection port, the molten aluminum can be sprayed out towards the mold cavity.

[0010] As a supplement to this technical solution, the bending angle of the curved channel is °. By optimizing the bending angle, the flow direction of the aluminum liquid is switched, the impact force of the aluminum liquid is reduced, and the aluminum liquid can move towards the mold cavity.

[0011] As a supplement to this technical solution, one end of the hopper body and the connecting rod adopts a vertical planar structure, and the other end of the hopper body adopts a conical structure that is larger at the top and smaller at the bottom.

[0012] As a supplement to this technical solution, the mold frame includes a left panel, a right panel, guide sleeves, and guide pillars. The left panel and the right panel are arranged vertically side by side. Four guide sleeves are evenly installed on the four corners of the left panel near the right panel. Four guide pillars, each corresponding to a guide sleeve, are evenly installed on the four corners of the right panel.

[0013] Beneficial effects: This invention relates to a feeding structure that prevents barrel erosion and improves service life. A hydraulic cylinder mounting bracket facilitates the installation of the lifting hydraulic cylinder. A connecting rod is installed on the lifting hydraulic cylinder to ensure that the connecting rod can move the feeding funnel up and down. By inserting the feeding funnel into the feed inlet, the molten aluminum enters along the feeding funnel without impacting the inside of the barrel, thus avoiding erosion. This invention features reduced production costs, increased production efficiency, and improved product quality. Attached Figure Description

[0023] Embodiments of the present invention relate to a feeding structure that prevents barrel erosion and improves service life, such as... Figure 1 — Figure 4 As shown, the device includes a mold frame 1, a die-casting mold 2, and a hydraulic cylinder mounting frame 4. The die-casting mold 2 is installed inside the mold frame 1. A material cylinder 3 for inserting into the die-casting mold 2 is installed on one side of the mold frame 1. An inlet 18 is provided on the upper side of the material cylinder 3. A hydraulic cylinder mounting frame 4 corresponding to the material cylinder 3 is installed on one side of the mold frame 1. A lifting hydraulic cylinder 5 with its main shaft facing downward is installed on the hydraulic cylinder mounting frame 4. A connecting rod 6 extending downward is installed on the main shaft of the lifting hydraulic cylinder 5. An inlet funnel 7 is installed on the lower end of the connecting rod 6. The lower end of the inlet funnel 7 is aligned with the inlet 18.

[0024] In this technical solution, the hydraulic cylinder mounting bracket 4 is installed to facilitate the installation of the lifting hydraulic cylinder 5. By installing the connecting rod 6 on the lifting hydraulic cylinder 5, it is ensured that the connecting rod 6 can move the feed funnel 7 up and down. By inserting the feed funnel 7 into the feed inlet 18, the aluminum liquid can enter along the feed funnel 7 without impacting the inside of the material cylinder 3, thus avoiding erosion.

[0025] As a supplement to this technical solution, the lower end of the connecting rod 6 is bent toward the feed hopper 7, and the bent end of the connecting rod 6 is inserted into the feed hopper 7 and welded to fix it. By inserting the connecting rod 6 into the feed hopper 7, the connection strength between the two is enhanced, and the welding fixation further improves the docking strength.

[0026] like Figure 5 — Figure 7 As shown, as a supplement to this technical solution, the feed hopper 7 includes a hopper body 12, a curved channel 13, and a discharge end 14. The hopper body 12 is a cone shape with a larger upper part and a smaller lower part. The lower end of the hopper body 12 is provided with a curved channel 13, which is curved towards the die-casting mold 2. The lower end of the curved channel 13 is provided with a discharge end 14.

[0027] In this technical solution, a curved channel 13 is set to reduce the impact force of the molten aluminum, and a discharge end 14 is set to ensure that the molten aluminum can be discharged smoothly, avoiding the molten aluminum from directly impacting the inside of the barrel 3, thereby protecting the structure of the barrel 3.

[0028] As a supplement to this technical solution, the discharge end 14 is provided with an elliptical injection outlet 15 arranged laterally. By providing the elliptical injection outlet 15, the aluminum liquid can be sprayed out towards the mold cavity.

[0029] As a supplement to this technical solution, the bending angle of the bending channel 13 is 90°. By optimizing the bending angle, the flow direction of the aluminum liquid is switched, the impact force of the aluminum liquid is reduced, and the aluminum liquid can move towards the mold cavity.

[0030] As a supplement to this technical solution, one end of the hopper body 12 and the connecting rod 6 adopts a vertical planar structure 16, and the other end of the hopper body 12 adopts a conical structure 17 with a larger top and a smaller bottom.

[0031] As a supplement to this technical solution, the mold frame 1 includes a left panel 8, a right panel 9, guide sleeves 10 and guide pillars 11. The left panel 8 and the right panel 9 are arranged vertically side by side. Four guide sleeves 10 are evenly installed on the four corners of the left panel 8 near the right panel 9. Four guide pillars 11, corresponding one-to-one with the guide sleeves 10, are evenly installed on the four corners of the right panel 9.

[0032] Example

[0033] During production, the die-casting mold 2 and mold frame 1 are first closed. Then, the lifting cylinder 5 is activated, the main shaft of the lifting cylinder 5 extends, and the feeding funnel 7 is lowered. The lower outlet of the feeding funnel 7 is inserted into the feeding port 18. Then, the aluminum liquid is taken out from the melting furnace with a crucible ladle and poured into the feeding funnel 7. The aluminum liquid will slide down along the inner wall of the feeding funnel 7. At the same time, the aluminum liquid is decelerated and turned through the curved channel 13, so that the flow direction of the aluminum liquid can be changed from vertical entry to horizontal injection, avoiding the aluminum liquid directly impacting the barrel 3, avoiding the barrel 3 from erosion, and improving the service life of the barrel. After the aluminum liquid is injected, the lifting cylinder 5 is activated to raise the feeding funnel 7. After the die-casting mold 2 is cooled, the mold is opened and the part is removed.
