Description

模架系统及其支撑脚 技术领域
本发明属于工业设备技术领域， 涉及注塑或压铸模具，特别地涉及一种用 于注塑或压铸模具行业的模架系统及其支撑脚。 背景技术
在注塑模具行业内，一种重要的组件是通用性很强的模架系统， 其主要包 括标准模架系统、 内部型芯 （简称型芯）、 滑块系统以及斜顶系统。
下面分别简单描述现有模具组件中的各个组成部分的现状及优缺点。 标准模架系统是模具行业内使用最频繁的一种标准件， 一般由面板、前模 板、 后模板、 支承板、 顶针面板、 顶针底板以及底板构成。 标准模架系统属于 模具中重要的部件， 为内部型芯提供着支承、 导向以及顶出等作用。 因此， 标 准模架系统的标准化在整个模具中发挥着至关重要的作用，主要表现为以下几 个方面。
第一，模架系统的标准化以及规格化， 使模具制造厂将工作重心放在重要 核心部件的高精度制造上，比如将主要精力投入到更加精密的内部型芯的制造 上， 从而减少很多非关键工作。
第二， 模架是大型部件， 需要大型机床加工， 而内部型芯则基本上是小型 部件， 需要小而精密的机床加工。模架的标准化使得专业模架制造行业得以形 成， 这样就使模具制造厂得以极大地减少在设备上的资金投入， 因为用于制造 大尺寸模架的大型机械加工设备通常都比较昂贵。
最后， 专业模架制造厂可以针对性购置专业机械加工设备， 提高模架的加 工精度和加工效率， 进而减少模具的制造成本， 缩短制造周期， 提高模架的制 造精度。
虽然现有的模架提供了上述优点， 但这种模架自身有着无法克服的缺点。 这些缺点具体表现在以下方面。
一、标准模架实际上其模架并未完全地实现标准化， 至少到目前为止， 它 仍依靠定制加工模式来提供， 只有极少数的小尺寸规格型号可购买到现货。模 架不能完全标准化的原因在于： 模架是大型零件， 需要大而重的钢材。 该钢材 价格不菲， 对于一般的模架厂来说， 需要准备较多资金来购买， 另一方面， 准 备很大批量的标准现货又会占用大量的流动资金，从而容易导致模架厂的运行 陷于瘫痪。
二、单个具体模具的独特性以及尺寸的不确定性导致标准模架的型号种类 繁多。 以目前中国最大的模架制造商 "龙记"的标准目录为例， 它的标准模架 大约有上万个型号，所以任何一个公司也不可能具有将上万个型号都准备大量 现货的能力。 而这种类繁多的标准模架则意味着其标准化程度很低。
三、现在的标准模架到了模具加工厂以后，仍然需要进行很多的加工作业， 比如：
1铣加工型芯固定槽坑 （铣框）；
2钻加工型芯固定螺丝过孔及固定螺丝头部台阶；
3钻加工产品顶杆过孔；
4钻加工模具冷却水道， 攻制冷却水管接头螺牙；
5钻加工顶针板复位弹簧孔；
6铣加工滑块、 滑动槽及止位定位装置；
7铣加工滑块顶部上方模架的避空位置；
8铣加工滑块锁紧块固定槽；
9钻加工滑块锁紧块固定螺丝过孔；
10铣或钻滑块驱动装置；
11钻加工注塑机顶杆过孔；
12钻、 攻牙加工顶针板底部垃圾避空螺钉 （垃圾钉）。
四、现有的模架基本上依靠订制加工的方式提供， 所以提供模架的时间比 较长，模具厂由订购到提取模架一般需要 3到 7天的时间， 这么长的时间导致 模具制造商的生产效率严重地下降。
五、 现有模架的顶出系统， 由于孔是钻、 镗加工形成的， 未能采用高精度 的磨削加工，所以顶出系统的导向精度低， 客户往往需要加订非标准的中导柱 系统来代替低精度的顶出导向系统。
六、 现有的模架用四个长圆柱型导柱定位， 依靠人力分开模具比较困难， 尤其在最后总整修配阶段， 尤为显著。 此外， 由于圆柱形导柱系统需要滑动， 圆柱形导柱系统的构件之间必然要保留一定的配合间隙，从而导致系统的定位 精度较低。
而标准型芯料，业界简称为标料， 是指按一定尺寸间隔规格而预制出的具 有较高尺寸精度及位置精度的标准型长方体材料， 一般为优质模具钢材料。 目 前实力雄厚的模架制造商商已经开始为模具制造商提供一些常用规格的标料， 可为模具制造商节省 2天左右的加工时间。但标料到模具厂以后， 仍有一些必 要的非关键性加工， 比如： 钻加工型芯固定螺丝孔； 为了避空模架上加工型芯 固定槽坑刀具所留下的转角刀具半径的残余材料，而需将标料四个尖角加工成 圆角； 另外由于模架上的型芯固定槽坑为单件加工， 尺寸精度不易控制， 基本 上都需要配磨标料。
综上所述， 研发一种改良的模架系统， 以便克服现有技术的缺点与不足确 有必要。 发明内容
本发明是为了解决现有技术存在的上述问题，而提供一种模架系统以及适 用于该模架系统的支撑脚， 以提高模具的标准化程度和模具组件的制造精度， 缩短造制周期和降低制造成本， 达到减少模具厂设备投资， 提高生产效率、减 少钢材浪费的目的。
为了实现上述目的之一， 本发明提供一种模架系统， 其包括下模架、 与该 下模架可分离地配合的上模架、 芯料以及多个导向定位机构， 其特征在于： 该 下模架包括用于承载芯料的多个互相隔开的下支撑脚和位于下支撑脚之间用 于顶出芯料的顶针装置； 该上模架包括多个互相隔开的上支撑脚， 该上支撑脚 与该下支撑脚一一对应； 每个导向定位机构连接相对应的上支撑脚和下支撑 脚。
该模架系统中： 该导向定位机构由导套和导柱构成， 该下支撑脚中开设有 第一定位孔， 该上支撑脚中开设有与第一定位孔位置相匹配的第二定位孔， 该 导套装设在该第一定位孔或第二定位孔内，该导柱装设在该第二定位孔或第一 定位孔内。
该模架系统中：该下支撑脚或上支撑脚该支撑脚包括基体、芯料支撑结构、 芯料固定结构。
为实现上述目的之二，本提供一种模具支撑脚，包括基体、芯料支撑结构、 芯料固定结构。该芯料支撑结构与该基体为一体或分体结构。该基体沿竖直方 向大致为柱状， 其侧面包括大致多面体形状的切除部分， 该切除部分从基体的 大致中部延伸到基体端面。
为本发明的优点在于：
一、本发明模具支撑脚， 由具有标准尺寸位置精度的支撑脚与相应的支承 板构成型芯定位系统， 无需加工专用型芯固定槽坑；
二、选择了在绝大部分模具的非加工位置上预制安装孔， 省却厂家此道工 序；
三、支撑脚只是在周边四个角落做来支承相应芯料， 支撑脚之间的位置空 出了产品型腔的顶出位置， 无需加工顶杆过孔；
四、 由于支撑脚与顶针底板只是局部地接触支承， 对于容易掉在此处的注 型产品的碎屑， 也不会被挤压滞留此处， 间接起到以前的垃圾钉作用；
五、 下支撑脚是依据标准型（下）芯料的大小灵活固定， 只需根据模具大 小， 制定大、 中、 小型号即可， 极大地减少了标准件规格型号， 使模架标准化 现货供应成为可能；
六、下支撑脚已经预制出标准型下芯料四个尖角形状的位置， 或已避空标 准型下芯料四个尖角位置的平台，因此标准型下芯料入厂后不需要再加工四个 角成圆角的工作；
七、 下支撑脚是以标准型下芯料为依附基础， 标准型下芯料无需磨配。 采用本发明的模架系统及其支撑脚，能够有效提高模具的标准化程度以及 制造精度， 缩短造制周期， 降低制造成本， 减少了模具厂设备投资， 提高了生 产效率， 减少钢材浪费， 并且极大程度地提高了模具的标准化水平。 附图说明

下支撑脚 100还包括设置于第一基体 110—端的第一垫板 150， 第一垫板 更正 91 150上设有连接通孔 151与下芯料固定结构 130的第一限位孔 132贯通。
上模架 30中的上支撑脚 300由第二基体 310、 上芯料支撑结构 390和上 芯料固定结构 330构成。
其中第二基体 310沿竖直方向大致为柱状，其沿竖直方向开设有与第一定 位孔 116相匹配的第二定位孔 316， 侧面包括大致多面体形状的第二切除部分 313。第二切除部分 313从第二基体 310的大致中部延伸到第二基体 310端面， 包括互成一定角度的第三侧壁 312和第四侧壁 314及构成上芯料支撑结构 390 的底壁。 第二切除部分 313， 第三侧壁 312与第四侧壁 314相交处设有第三凹 槽 311，与上芯料支撑结构 390相交线设有第四凹槽 315，用于避让上芯料 220 的外部棱角； 其中第四凹槽 315也可以是在第四侧壁 314与上芯料支撑结构 390相交的位置， 或者同时设置。 第二基体 310上第二切除部分 313的一侧横 向延伸出第二悬臂 320，与下支撑脚 100的第一悬臂 120相匹配，第二悬臂 320 与第二基体 310的轴心线垂直， 其上设有螺孔 /螺钉穿孔 322。

该模架机构，在当将第一支撑板 170以及下芯料 210放置到四个下支撑脚 100的四个下芯料支撑结构 190之间时， 由于第一、 第二凹槽 111、 115的存 在，第一支撑板 170及下芯料 210的四个棱角处不必加工形成圆角就可以自由 地放置到下芯料支撑结构 190上，而不会与下芯料支撑结构 190之间产生位置 干涉。 同样地， 当将第二支撑板 370以及上芯料 220放置到四个上支撑脚 300 的四个上芯料支撑结构 390之间时， 由于第三、 第四凹槽 311、 315的存在， 第二支撑板 370及上芯料 220的四个棱角处也不必加工形成圆角就可以自由地 放置到上芯料支撑结构 390上，不会与上芯料支撑结构 390之间产生位置干涉。 为了提高顶针装置的复位性能， 增设一复位机构， 该复位机构主要由第二 导柱 500、设置在顶针底板 141上的固定孔 143及顶针面板 142上与固定孔 143 相匹配的过孔 144构成。第二导柱 500自下支撑脚 100的第一悬臂 120的辅助 定位孔 121穿入， 经过过孔 144落入到固定孔 143中，第二导柱 500与辅助定 位孔 121和过孔 144滑动配合。 辅助定位孔 121中可以镶嵌有第二导套 510， 第二导柱 500滑动地穿过第二导套 510。 第二导套 510可以提高耐磨性能， 并 且可以使顶针面板 142被更加精确地导向。 此外， 第二导柱 500上套设弹簧 520， 弹簧 520位于第一悬臂 120与顶针面板 141之间。当上模架 30逐渐靠近 下模架 10时， 上支撑脚 300的第二基体 310推动第二导柱 500沿辅助定位孔 121滑动， 使顶针底板 141及顶针面板 142逐渐脱离第一支撑板 170及第一悬 臂 120， 达到复位目的。
为了便于存储及运输，在第一悬臂 120和第二悬臂 320上分别设置相互匹 配的穿孔 322和螺孔 122， 锁紧螺钉穿过穿孔 322并锁固于螺孔 122中， 实现 上模架 30与下模架 10的固定连接。
此外， 上支撑脚 100及 /或下支撑脚 300可以一体成型， 也可以由多个构 件组装而成， 如： 垫板和 （或）芯料支撑结构与基体可以是一体成型， 也可以 是分体式然后通过紧固件或焊接等方式固连。

五、 下支撑脚是依据标准型（下）芯料的大小灵活固定， 只需根据模具大 小， 制定大、 中、 小型号即可， 极大地减少了标准件规格型号， 使模架标准化 现货供应成为可能；
六、下支撑脚已经预制出标准型下芯料四个尖角形状的位置， 或已避空标 准型下芯料四个尖角位置的平台，因此标准型下芯料入厂后不需要再加工四个 角成圆角的工作；
七、 下支撑脚是以标准型下芯料为依附基础， 标准型下芯料无需磨配。 以上所揭露的仅为本发明的优选实施例而已，当然不能以此来限定本发明 之权利范围， 因此依本发明申请专利范围所作的等同变化， 仍属本发明所涵盖 的范围。
