Detailed ways

The utility model is described in detail below in conjunction with accompanying drawing and specific embodiment, present embodiment is based on the premise of the technical scheme of the utility model, has provided detailed implementation and specific operation process, but the protection scope of the utility model is not limited to the following the described embodiment.

As shown in the figure, the utility model is a small mold sliding heat preservation melting and casting furnace, including a melting furnace and a casting mechanism. The melting furnace is composed of a furnace body 1 and a furnace body support frame 6 arranged directly below the furnace body 1. The body 1 is a cylindrical structure with an upper opening, and an electric heating wire 2 is provided at the bottom thereof. In this embodiment, electric heating is used. According to actual production needs, gas heating or other heating methods can also be used. A melting chamber 3 is arranged above the electric heating wire 2 in the furnace body 1, and an insulating layer is filled between the electric heating wire 2, the melting chamber 3 and the inner wall of the furnace body 1. When the metal ingot in the melting chamber 3 is heated, the heat preservation The layer plays the role of heat accumulation, reducing heat loss and shortening the melting time of the metal ingot. When the metal ingot is completely melted, the insulation layer ensures that the temperature of the part of the liquid metal close to the 3rd wall of the melting chamber decreases slowly, and at the same time avoids accidents that may cause the operator Injury, the bottom of the melting chamber 3 has a liquid intake port 301 with a diversion groove 302, the diversion groove 302 passes through the insulation layer and extends to the outside of the furnace body 1, and the liquid intake port 301 is provided with a liquid intake port plug 4, After the metal ingot is completely melted, the liquid intake plug 4 is removed, and the liquid metal flows out along with the liquid intake port 301, and flows into the casting mold 7 along the diversion groove 302; the casting mechanism includes a casting mold 7, a mold tray 8, Die support frame 9, pulley 10 and heat preservation heating wire 11, the casting mold 7 is placed in the groove I set on the table top of the mold tray 8, the shape of the groove I matches the bottom surface of the casting mold 7, and the casting mold 7 is placed in the groove I After being fixed in it, there will be no sliding during the whole liquid metal pouring process. A plurality of mold trays 8 are arranged horizontally and placed in the groove II set on the table top of the mold support frame 9. The bottom surface of the mold tray 8 is provided with a 9 The pulley 10 that rolls horizontally in the groove II of the upper table. When the casting mold 7 on a mold tray 8 is filled with liquid metal, the operator slides the mold tray 8 to the side, and the vacant position is used by other molds to be poured. The tray 8 is occupied, and the pouring is continued until all the liquid metal in the melting chamber 3 flows out. A thermal insulation heating wire 11 is installed directly below the upper table of the mold support frame 9, and the liquid metal poured into the casting mold 7 is cooling. If the heat release is not uniform, the metal ingot will be distorted, deformed or cracked, which will affect the product phase of the metal ingot. The thermal insulation heating wire 11 arranged under the mold support frame 9 is slowly heated during the cooling process of the metal ingot, which can ensure the internal and external contact of the metal ingot. The temperature is lowered slowly to avoid losses caused by uneven heat release. The upper part of the furnace body 1 is provided with a furnace cover 5 that can completely cover the melting chamber 3. Covering the furnace cover 5 during the heating process of the metal ingot can reduce heat loss and avoid accidental injury caused by splashing of liquid metal.
