Description

一种农机铸件注射成型模具
技术领域
本实用新型涉及一种模具，特别涉及一种用于制造农机铸件的注射成型模具。
背景技术
机械零部件的传统加工方法：锻造/车削—热处理，这种加工方法生产的零部件质量取决于工作人员的技术水平高低，因此，企业对工作人员的技术水平很高，这对企业增加了招收员工的难度，也相对员工的工资会很高，提高了企业的生产成本；还有这种加工方法的生产效率很低，不能大批量生产，大大影响了企业的效益。因此，现在的企业都在使用注射成型模具，这种生产工艺，操作简单、对工作人员的技术水平要求低，而且可以大批量生产。零部件的质量要取决于填充-保压-冷却-脱模四大工艺步骤，但也还要看模具开模型腔的好坏。
实用新型内容
本实用新型的目的是提供一种结构简单、操作方便且高效率、高精度的农机铸件注射成型模具。
本实用新型的上述技术目的是通过以下技术方案得以实现的：一种农机铸件注射成型模具，包括上模、下模及型腔，所述型腔连接有注射浇道和浇口，所述型腔包括第一型腔和第二型腔，在第一型腔与第二型腔之间设有挡柱，所述挡柱为带有凹槽的圆柱；在第一型腔与第二型腔内沿它们的横向中心线各设有横向挡块；所述第一型腔和第二型腔的挡块的端部各开有“凹”型槽；在上模与下模的表面上，沿第一型腔与第二型腔的纵向中心线各开有“u”型槽，所述“u”型槽内安装有导杆。
作为优选，所述“凹”型槽的深度小于第一型腔与第二型腔的深度。
作为优选，所述上模上设有凸起，所述下模上开有与凸起相配合连接的固定孔。
作为优选，所述下模上设有脱模装置。
综上所述，本实用新型具有以下有益效果：
使用本实用新型模具装置，企业可以大批量生产，提高了效率；对操作员工的技术要求低；可以减少企业的生产成本；生产出的产品精度高，废品率低。
附图说明
图1是本实用新型下模的正视图；
图2是本实用新型上模的正视图。
具体实施方式
以下结合附图对本实用新型作进一步详细说明。
如图1-2所示，一种农机铸件注射成型模具，包括上模1和下模2。上模1与下模2的表面上分别设有凸起9和固定孔8，凸起9与固定孔8相互配合连接固定。注射成型模具的型腔3包括第一型腔31和第二型腔32，在第一型腔31与第二型腔32之间设有挡柱4，挡柱4是一根带有凹槽41的圆柱。在第一型腔31和第二型腔32内，沿第一型腔31和第二型腔32的横向中心线的方向各设有一块横向挡块10；在挡块10的端部处各开有“凹”型槽7。“凹”型槽（7）的深度小于第一型腔（31）与第二型腔（32）的深度。在上模1与下模2的表面上，沿第一型腔31与第二型腔32的纵向中心线各开有“u”型槽12，所述“u”型槽12内安装有导杆13。
此外，型腔3连通注射浇道5和浇口6，工作流程：液体通过注塑机的喷嘴经注射浇道5和浇口6注入模具型腔3，经保压、冷却后，通过设置在下模2的脱模装置11脱模。
