Description

Technical Field

[0001] This utility model relates to the field of casting equipment technology, specifically to a casting equipment for melting castings. Background Technology

[0002] In fields such as machinery manufacturing, automotive parts, and aerospace, castings serve as critical foundational components, and their quality directly determines the performance and reliability of the final product. The casting process, as the core of casting production, involves pouring molten metal that meets the required temperature and composition into a mold cavity to ultimately form a casting of a specific shape. During the molten metal melting process, impurities such as slag, metal oxides, and refractory material debris can easily become mixed in. If these impurities are not effectively removed before casting, they will enter the mold with the molten metal, leading to defects such as porosity, inclusions, and cracks in the casting, severely affecting its mechanical properties and surface quality.

[0003] An automatic casting device for aluminum castings, disclosed in publication number CN221734802U, includes a base, a hopper, and a casting pipe. A worktable is fixedly connected to the top of the base, and an adjustment assembly is provided between the worktable and the hopper. A stirring motor is fixedly connected to the top of the hopper, and a stirring shaft is fixedly connected to the output shaft of the stirring motor. Multiple stirring rods are fixedly connected to the outer side of the stirring shaft. This invention has the following advantages and effects: it allows for quantitative and speed-controlled adjustment of the molten metal according to actual needs, ensuring a suitable injection speed and quantity, avoiding waste, and improving production safety. Furthermore, the casting pipe can be adjusted and lowered to insert into the inlet of the casting mold, preventing spillage and waste. Simultaneously, it can heat and stir the molten metal, preventing it from solidifying and becoming difficult to flow out during casting.

[0004] While the aforementioned patent achieves quantitative and rate control of molten metal according to actual needs, ensuring an appropriate injection speed and quantity to avoid waste and improve production safety, and allows for adjustment and downward movement of the casting pipe to insert into the mold inlet to prevent spillage and waste, and also enables heating and stirring of the molten metal to prevent condensation and easy flow out, the device lacks a structure for filtering impurities from the molten metal. Impurities can enter the mold with the molten metal, leading to defects such as porosity, inclusions, and cracks in the castings, severely affecting the mechanical properties and surface quality of the castings. Utility Model Content

[0005] The technical problem to be solved by this utility model is as follows: to provide a casting device for casting smelting with high practicality and simple operation and structure, which solves the problem of filtering impurities in molten metal mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solutions: A casting apparatus for melting castings includes a heating tank, an inlet on the upper surface of the heating tank, a placement groove inside the inlet, a filter mechanism inserted inside the placement groove, a stirring mechanism fixedly connected to the top of the heating tank, and a pouring head on the lower surface of the heating tank. The filter mechanism includes a filter screen inserted into the placement groove, and a handle fixedly connected to the surface of the filter screen. The stirring mechanism includes a drive motor fixedly connected to the top of the heating tank, a stirring rod fixedly connected to the bottom of the drive motor, and scrapers fixedly connected to both sides of the stirring rod.

[0007] As a further embodiment of this utility model: a flow meter is installed on the surface of the pouring head, and a PLC controller is electrically connected to one side of the flow meter via a power cord. An electric control valve is electrically connected to one side of the PLC controller via a power cord. The electric control valve facilitates the control of the opening size of the pouring head.

[0008] As a further embodiment of this utility model: a sealing cover is hinged to one side of the liquid inlet, and a handle is installed on one side of the sealing cover, which facilitates the rotation of the sealing cover.

[0009] As a further embodiment of this utility model: a support platform is fixedly connected to the bottom of the heating barrel, and a workbench is fixedly connected to one side of the support platform, so that the support platform can easily support the heating barrel.

[0010] As a further embodiment of this utility model: a vertical plate is fixedly connected to the upper surface of the workbench, and a servo motor is fixedly connected to one side of one of the vertical plates, which facilitates the rotation of the lead screw.

[0011] As a further embodiment of this utility model: the output end of the servo motor is fixedly connected to a lead screw, the surface of the lead screw is threadedly connected to a placement plate, the surface of the placement plate is provided with a placement groove, and a casting mold is inserted into the placement groove, which facilitates the storage of the casting mold.

[0012] As a further embodiment of this utility model: a limiting hole is provided on one side of the placement plate, and a limiting rod is slidably connected inside the limiting hole. The limiting rod facilitates the limiting of the placement plate and makes it move stably.

[0013] The beneficial effects of this utility model are: 1. With the filter mechanism in place, a removable filter screen is installed inside the liquid inlet during use. The filter screen can be removed from the liquid inlet by pulling the handle on the surface of the filter screen. The filter screen can filter the molten metal injected into the heating tank, filtering out impurities mixed in the molten metal, improving the purity of the molten metal, and preventing impurities from entering the mold with the molten metal, which would cause defects such as porosity, slag inclusions, and cracks in the casting, seriously affecting the mechanical properties and surface quality of the casting.

[0014] 2. By setting up a stirring mechanism, in order to prevent the molten metal from condensing during use, a stirring rod is set inside the heating tank. The stirring rod is driven by the top drive motor to rotate and stir the molten metal. Scrapers are also set on both sides of the stirring rod. During the stirring process, the scrapers will scrape off the molten metal adhering to the inner wall of the heating tank, thereby achieving continuous and uniform heating of the molten metal, while avoiding the molten metal from adhering and solidifying, which would cause waste of raw materials and ensure the smooth progress of the casting process.
