汽车及其他行业产品有许多大型覆盖件.其深度较浅,面积较大.成形模具利用常用模具材料制造凸凹模,耗费工时多,成本高且生产周期长.改用低熔点合金材料制造凸凹模,生产周期短,材料可反复使用,大大降低了生产成本,有广阔的发展前途.3150kN单动液压机原有顶出机构,可以实现拉伸件的反压边功能.而低熔点合金凹模是直接浇注在熔箱内,重量大,移动困难.如果用反压边,需将凹模固定在上滑块上,这种压边形式,把低熔点合金制造的大重量凹模固
Automotive and other industries have many large-scale cover products. The depth of the shallow, large area. Molding molds using common mold material manufacturing punch and die, and more time and labor costs, high cost and long production cycle. Use of low melting point alloy material to make punch and die , The production cycle is short, the material can be reused, greatly reducing the cost of production, has broad prospects for development .3150kN single-action hydraulic press the original ejection mechanism can achieve the anti-pressure side of the tensile edge function. And low melting point alloy die is Direct casting in the box, heavy weight, difficult to move.If the counter-pressure side, the die must be fixed on the slider, the pressure side of the form, the low melting point alloy made of heavy-duty die-solid
