Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of casting, in particular to an automatic casting system. BACKGROUND
[0002] As a basic process in manufacturing industry, casting is widely used in the fields of automobile, machinery, aerospace, etc., and its core is to inject molten metal or alloy into a mold cavity, and then form a specific shape of casting after cooling and solidification. With the improvement of industrial automation level, the traditional casting system gradually cannot meet the production demand of high precision, high efficiency and low defect.
[0003] However, the molten liquid delivery of the existing casting system adopts an open pipeline or a simple closed structure, and lacks an inert gas protection mechanism. The molten liquid directly contacts with air during the delivery process, and is easy to generate oxidation slag through oxidation reaction.

When the mold cavity structure is complex or the volume is large, the molten liquid is difficult to completely fill the dead angle of the cavity, and problems such as material shortage and shrinkage hole are easy to occur, which requires subsequent repair welding or scrap processing, thereby increasing the production cost.

The moving seat 45 is slidingly connected to the outer ring surface of the plurality of guide rods 6. The second cylinder 41 is fixedly installed through the middle of the second side seat 5. The movable rod of the second cylinder 41 is fixedly connected to the middle of the moving seat 45. The movable die seat 42 is fixedly connected to the other side of the middle of the moving seat 45. The other side of the movable die seat 42 is fixedly connected with two groups of mirror-symmetrical limiting assemblies 43 and one group of blocking assemblies 44. The blocking assembly 44 is located in the upper middle position between the two groups of limiting assemblies 43.

The blocking assembly 44 includes a half-dental threaded rod 441, a spring 442, a connecting plate 443, guide blocks 444 and a hole seat 445. The two groups of guide blocks 444 are fixedly installed in the inside of the movable die seat 42. The connecting plate 443 is fixedly connected to the upper end of the two groups of guide blocks 444. The half-dental threaded rod 441 is slidingly connected to the middle of the connecting plate 443. The spring 442 is sleeved to the outside of the half-dental threaded rod 441 through a nut, and the lower end of the spring 442 abuts against the upper side of the connecting plate 443. The hole seat 445 is slidingly connected to the middle of the two groups of guide blocks 444. The hole seat 445 is fixedly connected to the lower end of the half-dental threaded rod 441.
[0026] In this embodiment, the moving mold mechanism 4 serves as the movable end of the mold, undertaking the functions of mold fixing, mold closing drive, and demolding assistance, and achieving efficient operation through the linkage of multiple components. The movable base 45 serves as the supporting foundation. Driven by the second cylinder 41, it slides horizontally along the guide rod 6, causing the moving mold base 42 to move closer to or away from the fixed mold base 22, thus completing the mold closing and mold opening actions. In the limiting assembly 43, the third cylinder 431 is fixed by the second connecting frame 432. Its movable rod extends and retracts to push the top module 433 to move within the moving mold base 42. The two sets of top modules 433 clamp and embed the other half of the mold into the moving mold base 42 from both sides, realizing the rapid fixing and disassembly of the mold. In the sealing assembly 44, the guide block 444 provides sliding guidance for the connecting plate 443 and the hole seat 445. The half-threaded rod 441, through the cooperation of the nut and the spring 442, can adjust the initial height of the hole seat 445 to adapt to molds of different sizes. When the mold is closed, the hole seat 445 cooperates with the tilting rod 222 to seal the mold opening. When the mold is opened, the elastic force of the spring 442 pushes the hole seat 445 to reset, releasing the sealing state and facilitating demolding.
[0027] The method of use and working principle of this device: One half of the mold is installed in the middle of the fixed mold base 22 by bolts, and the other half of the mold is embedded in the middle of the moving mold base 42. The movable rods of the two sets of third cylinders 431 are extended, pushing the top module 433 to move along the second connecting frame 432 towards the middle of the moving mold base 42. The two sets of top modules 433 abut against the mold, thereby completing the mold fixing. The height of the half threaded rod 441 is adjusted by wrench holding the nut at the upper end of the half threaded rod 441 and rotating it, thereby adjusting the hole seat 445. The height is adjusted to match different sizes of molds within a certain range. The movable rod of the second cylinder 41 is extended to horizontally push the moving seat 45 along the guide rod 6, so that the moving seat 45 moves closer to the fixed mold seat 22. The positioning hole of the moving mold seat 42 is first aligned with the positioning rod 221 for positioning. Then, the oblique hole in the middle of the hole seat 445 is aligned with the tilting rod 222 and inserted. The tilting rod 222 applies a downward force to the hole seat 445 to seal the mold opening until the two molds are closed and a closed cavity is formed. Then, the first cylinder 231 is started, its movable rod retracts and pulls the hook rod 233 upward. The inclined protrusion at the lower end of the hook rod 233 slides in the groove on the side of the perforated plate 234. Since the perforated plate 234 can only move horizontally in the fixed mold base 22 and cannot move up and down, the horizontal component of the force applied by the hook rod 233 to the perforated plate 234 causes the perforated plate 234 to move horizontally outward, so that the perforated plate 234 no longer fits the air hole in the middle of the fixed mold base 22, allowing the closed cavity to be temporarily ventilated. The molten liquid is injected into the temporary storage bin 72 through the infusion pipe 71, and at the same time, the gas pump 73 is started to inject the inert gas connected outside into the temporary storage bin 72, the inert gas wraps the molten liquid to avoid the molten liquid from being oxidized or contaminated by the air, and at the same time, the molten liquid is pressurized to be transported into the channel seat 74, the molten liquid is injected into the two mold combined molds through the conduit 76 and the liquid inlet pipe 77, the gas is discharged through the gas hole in the middle of the fixed mold seat 22, thereby realizing that the molten liquid fills the entire cavity, when approaching the last stage of injection, the movable rod of the first gas cylinder 231 is elongated to make the hole disc 234 return to the initial position and block the gas hole in the middle of the fixed mold seat 22, after cooling, the molten liquid solidifies and is shaped; After a period of time, the movable rod of the second gas cylinder 41 is retracted to pull back the moving seat 45, the movable mold seat 42 and the fixed mold seat 22 are separated, and the two molds are separated, the inclined rod 222 is separated from the hole seat 445, the spring 442 is compressed to generate elastic force on the hole seat 445, so that the hole seat 445 moves upward and no longer blocks the mold opening, which is convenient for subsequent demolding.
[0028] Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
