Embodiment 1

[0015] Embodiment one: if figure 1 As shown, the selected silicate fiber accounts for 60%, phenolic resin 38%, and silane coupling agent 2%. Add it into the mixer 1 and stir until the material is evenly stirred. Open the valve 2, the uniformly stirred composite material enters the dilution tank 3, and adds water to dilute at a concentration of 8 / 1000; In the slurry chamber 61 of the molding machine 6, the mold 62 of the required product specification is installed on the molding machine, the mold 62 automatically sinks into the slurry chamber 61, and vacuum absorbs the slurry according to the time set by the program. After completion, the anti-transfer mold 63 is automatically lifted to absorb After the pipe fittings are wet, they are moved forward by the cylinder of the slide rail 64 and are automatically unloaded by the stepping dryer 7; the formed wet pipe fittings enter the drying chamber, and after being dried by high-temperature circulating hot air, they are evaporated a...

Embodiment 2

[0016] Embodiment 2: the selected silicate fiber accounts for 70%, phenolic resin 35%, and silane coupling agent 5%. Add it into the mixer 1 and stir until the material is evenly stirred. Open the valve 2, the uniformly stirred composite material enters the dilution tank 3, and adds water to dilute at a concentration of 8 / 1000; In the slurry chamber 61 of the molding machine 6, the mold 62 of the required product specification is installed on the molding machine, the mold 62 automatically sinks into the slurry chamber 61, and vacuum absorbs the slurry according to the time set by the program. After completion, the anti-transfer mold 63 is automatically lifted to absorb After the pipe fittings are wet, they are moved forward by the cylinder of the slide rail 64 and are automatically unloaded by the stepping dryer 7; the formed wet pipe fittings enter the drying chamber, and after being dried by high-temperature circulating hot air, they are evaporated and dehydrated to a moistu...

Abstract

The invention relates to a runner tube for casting and manufacturing equipment of the runner tube. The runner tube is prepared from the following raw materials: 60-70% of silicate fiber, a reinforcing material which accounts for 30-40% of the total weight, and an adhesive material which accounts for 2-5% of the total weight. The preparation method comprises the following steps: adding water into the raw materials according to the concentration of 0.8%, stirring, diluting, molding, drying, shaping, trimming and inspecting, thereby obtaining the runner tube. The manufacturing equipment of the runner tube for casting according to claim 1 comprises a stirring machine, a dilution tank, a circulation slurry tank, a power pump, a molding pump, a drying machine and a shaping machine, wherein the stirring machine is connected with the dilution tank; the dilution tank is connected with the circulation slurry tank; the circulation slurry tank is connected with the molding machine through the power pump; the drying machine and the shaping machine are sequentially arranged on the rear passage of the shaping machine. After molten iron casting, carbide can be formed in the runner tube provided by the invention, casting sprue iron can be directly recycled, and casting sand can be easily recycled and treated.

Description

technical field [0001] The invention relates to a sprue pipe for casting and its manufacturing equipment. Background technique [0002] The foundry industry is the basic industry of the machinery industry. Casting occupies a very important position in the machinery industry. Casting technology is one of the main technologies for the sustainable development of the national economy and is the supply side of mechanical products. According to the data, there are 22,000 foundry enterprises in my country in 2015, which provide 25 million tons of castings for various sectors of the national economy. With the reputation of Chinese manufacturing abroad, the vigorous development of the machinery manufacturing industry, the castings of the foundry industry are large in size, heavy in weight, complex in shape, and have high technical requirements. Products must be filled with high-temperature molten iron through the installation of sprue pipes to ensure product quality. [0003] At pre...
