38、VD 齿轮模具，所生产的这 类齿轮塑件的尺寸精度、同轴度、跳动等要求都达到了国外同类产品的 水平，而且还采用最新的齿轮设计软件，纠正了由于成型收缩造成的齿 形误差，达到了标准渐开线齿形要求。还能生产厚度仅为 0.08mm 的一模 两腔的航空杯模具和难度较高的塑料门窗挤出模等等。注塑模型腔制造 精度可达 0.020.05mm，表面粗糙度Ra0.2m，模具质量、寿命明显提 高了，非淬火钢模寿命可达 1030 万次，淬火钢模达 501000 万次， 交货期较以前缩短，但和国外相比仍有较大差距，具体数据见表一。 成型工艺方面，多材质塑料成型模、高效多色注射模、镶件互换结 构和抽芯脱模机构的创新设计方面

39、也取得较大进展。气体辅助注射成型 技术的使用更趋成熟，如青岛海信模具有限公司、天津通信广播公司模 具厂等厂家成功地在 2934 英寸电视机外壳以及一些厚壁零件的模具 上运用气辅技术， 一些厂家还使用了 C-MOLD 气辅软件， 取得较好的效果。 如上海新普雷斯等公司就能为用户提供气辅成型设备及技术。热流道模 具开始推广，有的厂采用率达 20%以上，一般采用内热式或外热式热流 道装置，少数单位采用具有世界先进水平的高难度针阀式热流道装置， 少数单位采用具有世界先进水平的高难度针阀式热流道模具。但总体上 热流道的采用率达不到 10%，与国外的 5080%相比，差距较大。 在制造技术方面，CAD/C

40、AM/CAE 技术的应用水平上了一个新台阶， - 9 - 以生产家用电器的企业为代表，陆续引进了相当数量的 CAD/CAM 系统， 如美国 EDS 的 UG、 美国 ParametricTechnology 公司的 Pro/Emgineer、 美国 CV 公司的 CADS5、英国 Deltacam 公司的 DOCT5、日本 HZS 公司的 CRADE、以色列公司的 Cimatron、美国 AC-Tech 公司的 C-Mold 及澳大利 亚 Moldflow 公司的 MPA 塑模分析软件等等。这些系统和软件的引进，虽 花费了大量资金，但在我国模具行业中，实现了 CAD/CAM 的集成，并能 支持

41、 CAE 技术对成型过程，如充模和冷却等进行计算机模拟，取得了一 定的技术经济效益，促进和推动了我国模具 CAD/CAM 技术的发展。近年 来，我国自主开发的塑料模 CAD/CAM 系统有了很大发展，主要有北航华 正软件工程研究所开发的 CAXA 系统、 华中理工大学开发的注塑模 HSC5.0 系统及 CAE 软件等，这些软件具有适应国内模具的具体情况、能在微机 上应用且价格较低等特点，为进一步普及模具 CAD/CAM 技术创造了良好 条件。 近年来，国内已较广泛地采用一些新的塑料模具钢，如:P20、 3Cr2Mo、PMS、SM、SM等，对模具的质量和使用寿命有着直接的重大 的影响，但总体使用

42、量仍较少。塑料模标准模架、标准推杆和弹簧等越 来越广泛地得到应用， 并且出现了一些国产的商品化的热流道系统元件。 但目前我国模具标准化程度和商品化程度一般在 30%以下，和国外先进 工业国家已达到 70%-80%相比，仍有很大差距。表一、国内外塑料模具 技术比较表?项目国外国内注塑模型腔精度0.0050.01mm0.020.05mm 型腔表面粗糙度 Ra0.010.05 mRa0.20 m 非淬火钢模具寿命 1060 万次 1030 万次淬火钢模具寿命 160300 万次 50100 万次热流道模 具使用率 80%以上总体不足 10%标准化程度 7080%小于 30%中型塑料模 生产周期一个月左右 24 个月在模具行业中的占有量 3040%2530% 据有关方面预测，模具市场的总体趋热是平稳向上的，在未来的模具市 - 10 - 场中，塑料模具的发展速度将高于其它模具，在模具行业中的比例将逐 步提高。随着塑料工业的不断发展，对塑料模具提出越来越高的要求是 正常的，因此，精密、大型、
