本申请涉及模具技术领域，例如涉及一种送料子模及翅片模具。
背景技术
空调行业的翅片型号复杂多变，客户对空调模具的要求也日益增多。翅片在生产过程中，通常要进行冲孔、引伸、翻边等多种工艺，一般一副模具只能运用于相同孔径的翅片生产中，通用性较差，特别是送料子模，送料指的尺寸应与加工孔尺寸适配，否则影响进料精度，而更换送料子模往往需要拆卸大模板。因而，设计一些可更换子模以适用不同孔径的模具，最大的难点就是在子模的变换上。
发明内容
本申请提供一种送料子模，实现多套孔径送料子模的便捷更换工作，以适用多型号产品送料。
本申请还提供一种通用性强、送料子模更换方便的翅片模具。
一种送料子模，包括送料托板及位于送料托板下方的多个送料指组件，送料指组件的下方设置有切换机构，切换机构包括顶压块、送料推块和调整螺杆，顶压块放置于送料推块上且抵靠于送料指组件上，送料推块的表面设置有锯齿状的凸部，顶压块的下表面上设置有与凸部适配的凹槽，调整螺杆设置为作用于送料推块上以改变送料推块的位置，在送料推块相对于顶压块顺着或逆着凸部齿向移动的情况下，顶压块设置为在被顶升或降下的情况下驱动送料指组件升起工作或降下不工作。
一种翅片模具，其包括上述的送料子模。

本实施例以适应双孔径设置两个送料指组件2为例说明，将其分为固定送料指组件2a和活动送料指组件2b，可以仅在活动送料指组件2b的下方设置切换机构3，驱动切换机构3，当活动送料指组件2b高于固定送料指组件2a时，由活动送料指组件2b进行送料；当活动送料指组件2b低于固定送料指组件2a时，由固定送料指组件2a进行送料。
另外，送料托板1的上方设置有依靠自重压覆料片的送料压板4，送料托板1上竖立有导杆5，送料压板4由导杆5导向，以保持送料过程中料片平整，无拱起情况，以顺畅进行送料。送料托板1的上方设置有压料块6，压料块6与送料托板1之间形成恰好使料片通过的固定间隙，固定间隙根据实际料片厚度调整。
本实施例还提供一种翅片模具，包括上述的送料子模。
综上，上述的送料子模及翅片模具采用切换机构以控制一个送料指组件工作或不工作，从而能够根据需要选择相应孔径的送料指进行送料，送料子模更换方便、快速，降低了成本，提高了模具通用性。
