压铸模与冲模等其它模具相比,制造周期长(2～3月)、精度高(2～4级)、成本贵(2～3千元),有些压铸模制造周期甚至长达半年,成本一万多元。由此可见,一副压铸模和一台普通机床价值相当。每台机床出厂均有包括性能、使用要求等内容的说明书。但压铸模,据我所知,没有一个厂有说明书(国外称为压铸模技术档案)。因此,目前各厂普遍存在压铸模管理混乱、质量和安全事故频繁、事故责任不清、使用寿命短等问题。为克服这些弊端,国外如瑞士、西德等,对每副压铸模都建立了技术档案。 技术档案包括以下几个部分:
Compared with other molds, such as die-casting molds, the manufacturing cycle is long (February to March), the precision is high (from 2 to 4), the cost is expensive (2 to 3 thousand), and the manufacturing cycle of some die- More than 10,000 yuan. Thus, a die-casting mold and an ordinary machine worth quite. Each machine has the factory, including performance, use requirements and other content of the manual. But the die-casting mold, as far as I know, there is not a manual (foreign known as die-casting mold technology files). Therefore, at present, there are common problems such as chaos of die-casting mold management, frequent quality and safety accidents, unclear responsibility of accidents and short service life. To overcome these shortcomings, foreign countries such as Switzerland, West Germany, each pair of die-casting mold have established a technical file. Technical file includes the following sections:
