Description

一种三通模具的制造方法
技术领域
本发明涉及一种模具，更确切地说，是一种三通模具的制造方法。
背景技术
模具是工业生产上用以注塑、吹塑、挤出、压铸或锻压成型、冶炼、冲压等方法得到所需产品的各种模子和工具。简而言之，模具是用来制作成型物品的工具，这种工具由各种零件构成，不同的模具由不同的零件构成。它主要通过所成型材料物理状态的改变来实现物品外形的加工。素有“工业之母”的称号。目前用于三通成型的模具材料整体不够稳定，经常需要修模甚至重新开模，增加了企业负担，降低了企业的整体竞争力。
发明内容
本发明主要是解决现有技术所存在的技术问题，从而提供一种经久耐用的三通模具的制造方法。
本发明的上述技术问题主要是通过下述技术方案得以解决的：
一种三通模具的制造方法，包含如下步骤：
①按重量份取氧化铝200-230份，锂0.2-0.5份，铍0.8-1.2份，氧化镁18-24份，硫酸铜6-10份，瓷石砂30-35份，钴土矿砂10-15份，脱水氯化锌0.3-0.5份；
②将所取原料加入球磨机进行粉碎磨粉，所得粉末充分混合，然后将混合后的粉末原料成型为具有规则形状的毛坯；
③将所得毛坯进行预烧结，烧结温度控制在1100-1300℃，时间控制在15-30分钟，然后取出自然冷却至室温；
④对毛坯进行车坯处理，使车坯后初期模具的尺寸较最终模具尺寸稍大；
⑤将车坯完成后的模具进行高温烧结处理，首先将炉温以50℃/分的速度升高到1900℃，保持15-20分钟，然后将炉温以30℃/分的速度降低到1600℃，保持10-15分钟，然后将炉温以50℃/分的速度降低到800℃，保持6-9分钟，然后将炉温以20℃/分的速度降低到500℃，保持10-15分钟，然后将炉温以50℃/分的速度升高到1800℃，保持8-12分钟，然后将炉温以30℃/分的速度降低到1000℃，保持5-8分钟，然后将炉温以10℃/分的速度降低到700℃，保持10-15分钟，然后将炉温以20℃/分的速度降低到400℃，保持6-12分钟，最后将模具取出，自然冷却至室温；
⑥对模具进行打磨，使模具尺寸达到最终设计尺寸即得。
本发明的三通模具的制造方法以金属氧化物与非金属矿砂为主要原料制成三通模具，模具整体结构致密，高温烧结过程让模具内部应力更均匀，让模具的热膨胀影响达到最小，从而大大提高了三通模具的整体稳定性，延长了模具的使用寿命，降低了制造成本。
