在全国经济建设大趺进的今天,锻造业也必须符合多快好省的的方针。推广胎模锻造是提高锻造效率的好办法。但是胎模制造却是一个费工的过程,而形状较复杂的胎模加工更感困准。现在我们采用压模注制造胎模。将模块加热后压出模腔,经钳工锉光即可,不必经过机械加工。所以锻造车间自己就可以制造。有些胎模用机械加工很困维,而用压模法很容易就可制成。如我们加工螺丝六方头的冲头时,其六方对角的圆弧为R_1,用铣刀铣不出来,用插刀就得将六方部分分升制造,然 Today, when the economy of the country is undergoing economic development, the forging industry must also meet the principle of giving promises and merits. Promotion of tire forging is to improve the efficiency of forging a good way. However, the manufacture of tire molds is a laborious process, while the more complex shape of the mold processing more intricate. Now we use injection molding injection mold. The module is heated out of the mold cavity, the fitter rasp light, without going through mechanical processing. So forging shop itself can create. Some tire molds are very difficult to machine, but they can easily be made by compression molding. If we process the head of the hex head screw, the hexagonal arc R_1, with a milling cutter can not be out, with the knife will be part of the hexagonal part of the manufacture,
