Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a tilting casting and heat preservation mold for an air chamber of an intercooler. Background Art

[0002] Turbocharged engines must use intercoolers to reduce the intake temperature to increase engine power, prevent engine combustion temperature from being too high, causing knock and other faults, reduce the content of nitrogen dioxide in engine exhaust, and reduce air pollution. The market prospects are very broad. The intercooler consists of two major parts, a core and two air chambers. At present, the production process of the intercooler air chamber mainly includes sand mold gravity casting and metal mold gravity casting. Generally, small batch products use sand mold gravity casting, and large batch products use metal mold gravity casting.

[0003] The air chamber of the intercooler is a thin-walled part. The heat released when the aluminum liquid solidifies is relatively small, which is not enough to heat the mold. Therefore, a heating tube needs to be placed on the mold to heat the mold so that the mold temperature is controlled at a temperature suitable for casting. Otherwise, the product is prone to insufficient casting and cold shut. The main shortcomings of the existing mold structure are: first, the back of the mold is not hollowed out, and the iron-aluminum ratio of the mold is very large, resulting in limited heat released when the aluminum liquid solidifies to heat the mold; second, the heating tube on the mold is difficult to disassemble and assemble. If aluminum liquid flows out during casting, there will be certain safety hazards; third, the mold surface is not insulated, and the mold surface dissipates heat very quickly.

[0004] In response to the above problems, the intercooler air chamber tilting casting insulation mold announced in Chinese patent publication with announcement number CN203459626U has the following technical points: it includes an upper mold and a lower mold, and a mold cavity for molding the product after mold closing is arranged on the opposite front sides of the upper and lower molds, and the back sides of the upper and lower molds are provided with a plurality of hollow parts, and a thin-wall partition wall for support is arranged between adjacent hollow parts, and each hollow part is provided with insulation material.

[0005] In actual operation, it was found that the above scheme still has at least the following defects: although the mold can reduce the heat dissipation of the mold, it cannot prevent the temperature of the mold from continuing to drop, which is not conducive to maintaining a constant temperature and affects the quality of casting the intercooler air chamber. For this reason, we propose an intercooler air chamber tilting casting insulation mold to solve the above problems. Utility Model Content
