[0002] Metal casting is a process of melting metal into a liquid that meets certain requirements and pouring it into a mold. After cooling, solidification, and finishing, a casting with a predetermined shape, size, and performance is obtained. The casting blank is almost formed, so it can achieve the purpose of no mechanical processing or minimal processing, which reduces costs and time to a certain extent. Casting is one of the basic processes in the modern machinery manufacturing industry.

[0003] Existing Chinese patent document CN202121885318.4 discloses a casting furnace for hardware casting, including a base, a casting furnace, and a lid. The casting furnace is fixedly connected to the top of the base, and the lid is connected to the top of the casting furnace by a hinge. A display screen is fixedly connected to one side of the base. An inner furnace is provided in the casting furnace, and a distance is provided between the inner furnace and the casting furnace. An opening is provided on one side of the casting furnace, and an insulation component is provided in the opening. This type of casting furnace for hardware casting can replace the insulation layer according to actual conditions, avoiding aging of the insulation layer, reducing the thermal insulation effect of the insulation layer, and preventing the waste of resources caused by abandoning the entire hardware casting casting furnace if the surface of the insulation layer is damaged, which can extend the service life.

[0004] However, the above patent has certain defects when used. After the casting furnace melts the metal, the molten iron needs to be taken out from the inside of the casting furnace, and the casting process cannot be carried out quickly. In addition, manually taking out the molten iron is very dangerous, which greatly reduces work efficiency.

[0005] For this reason, a precision casting furnace with automatic casting positioning is proposed to solve the above-mentioned problems. Utility Model Content

[0024] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] like Figures 1 to 5 As shown, a precision casting furnace with automatic casting and positioning includes a workbench, four support legs 2 are provided at the lower end of the workbench, and the support legs 2 are fixed around the lower end of the workbench. A casting furnace body 9 is provided at the upper end of the workbench. The casting furnace body 9 is the main part for melting and casting metal materials. A heating element is provided inside for heating the metal material to a molten state. A furnace cover 92 is provided at the upper end of the casting furnace body 9. The furnace cover 92 covers the upper end of the casting furnace body 9 and is used to seal the furnace body, reduce heat loss, and maintain a stable temperature in the furnace. A filling hopper 8 is provided on the furnace cover 92. The filling hopper 8 is connected to the interior of the casting furnace body 9 and is used to add metal material to the casting furnace body 9.

[0027] A support plate 4 is provided between the support legs 2, and a casting mold is provided at the upper end of the support plate 4. The casting mold includes a lower mold 5 and an upper mold 6. An injection pipe 61 is provided on the upper surface of the upper mold 6. The lower end of the injection pipe 61 is connected to the interior of the upper mold 6, and the upper end is connected to the casting furnace body 9. A valve is provided inside the injection pipe 61, and the injection pipe 61 is used to guide the molten metal material into the mold cavity.

[0028] An insulation cover 1 is provided at the upper end of the workbench, and the insulation cover 1 is provided above the casting furnace body 9. The insulation cover 1 can form an insulation layer, reduce heat loss from the furnace body, and improve energy utilization efficiency. A cabinet door 3 is provided on the front of the insulation cover 1, and a handle 31 and a window 32 are provided on the surface of the cabinet door 3. The cabinet door 3 is convenient for the operator to open and check the situation inside the furnace. It is also equipped with a handle 31 and a window 32. The window 32 is made of high-temperature resistant transparent material to improve the convenience of use and the safety of observation.

[0029] A stirring device is provided inside the casting furnace body 9, and the stirring device includes a motor 7. The motor 7 is fixed on the top of the heat preservation cover 1. The output end of the motor 7 is provided with a rotating shaft 71, and the rotating shaft 71 extends into the casting furnace body 9. A plurality of stirring rods 72 are provided on the outer peripheral wall of the rotating shaft 71. The motor 7 of the stirring device drives the rotating shaft 71 to rotate, thereby driving the stirring rods 72 to stir in the casting furnace body 9. During the stirring process, the stirring rods 72 break up and mix the metal materials to ensure that the materials are heated evenly, increase the melting rate and melting effect, and thus improve the quality and performance of the castings.

[0030] The upper end of the casting furnace body 9 is provided with a mounting block 93, and two mounting blocks 93 are provided and symmetrically arranged;

[0031] A fixing block 94 is provided on the outer peripheral wall of the furnace cover 92, and a pin shaft 95 is provided on both side walls of the fixing block 94. One end of the pin shaft 95 is set in the fixing block 94, and the other end is set on the side wall of the mounting block 93. The furnace cover 92 is rotatably connected to the casting furnace body 9 through the pin shaft 95. The rotational connection between the furnace cover 92 and the casting furnace body 9 is realized by the pin shaft 95, which facilitates the opening and closing of the furnace cover 92.

[0032] The furnace cover 92 is provided with a handle 91 to facilitate an operator to manually lift or move the furnace cover 92, thereby increasing the convenience of use.

[0033] The operating principle of the utility model is as follows: when in use, the metal material to be cast is placed in the pouring hopper 8 of the casting furnace body 9, and heating is started. The heating element inside the casting furnace body 9 starts working, converting electrical energy into thermal energy to heat the metal material. As the temperature rises, the metal material gradually melts to form molten metal;

[0034] During this process, the stirring device starts to work, and the motor 7 drives the rotating shaft 71 and the stirring rod 72 to rotate, stirring the molten metal to improve the uniformity of heating and the melting rate. When the molten metal reaches the casting temperature, the valve in the injection pipe 61 is opened, and the molten metal flows rapidly into the upper mold 6 of the casting mold through the injection pipe 61 and fills the mold cavity.

[0035] After the casting is completed, the valve of the injection pipe 61 is closed and the molten metal is allowed to cool and solidify in the mold. When the casting is completely cooled and solidified, the upper mold 6 and the lower mold 5 of the casting mold are opened and the casting is taken out. There is no need to manually remove the molten metal during the casting stage, which greatly improves work efficiency and reduces risk.

[0036] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
