为提高刹车盘双胞胎模具的热芯盒的排气性能和加工工艺性,对芯盒进行了结构改进。增设梯形排气台和筋头排气孔,减少排气塞数量,降低了钳工工作量,芯盒维修方便,生产成本低。提高上下芯盒配合尺寸精度,改善其配合品质,提高了热芯盒的制芯品质。在热芯盒下芯盒芯头部位加设波浪排气槽,改善铸造生产时的排气性能。
In order to improve the exhaust performance and processing technology of the hot core box of the brake disc twin mold, the core box is structurally improved. Addition of trapezoidal exhaust gas stations and ribs vent, reducing the number of exhaust plugs, reducing fitter workload, core box easy maintenance, low production costs. Improve the upper and lower core box with the dimensional accuracy, improve its cooperation with the quality and improve the quality of core-making system. In the core box under the hot box core core head plus wave exhaust groove to improve the exhaust performance of the casting production.
