技术领域
本公开涉及模具脱模结构技术领域，尤其涉及一种模具斜顶机构及其操作方法。
背景技术
塑胶产品有倒扣、扣位等结构，在注塑产品成型后，采用斜顶结构顶出脱模，斜顶设计工艺相对简单，成本也较低。斜顶是顺着一定角度斜着向前推进，当向前一段行程后，这个扣位的位置就脱离了塑胶的内侧接触，从而使产品能顺利取出。
现有的斜顶结构，斜顶杆一般是直杆，倾斜占用的空间较大，斜顶角度越大，倾斜越大。当产品扣位较多，需要设置多个斜顶，以进行多方位的斜顶出模，在斜顶底部的延长杆段，斜顶杆容易产生交叉干涉，斜顶空间不足，容易造成具有倒扣的产品无法出模，粘在斜顶上。另一种斜顶杆底部采用直的斜顶座结构，将斜顶底部做直，可以解决狭小空间内布置斜顶问题，但是此种结构的斜顶杆的导向结构较少，斜顶杆和斜顶座运动方向不同，角度不能做大，否则容易发生卡死现象。
发明内容
本公开的目的例如包括提供一种模具斜顶机构及其操作方法，以解决现有技术中斜顶空间占用大、斜顶结构易卡死的问题。

本公开实施例提供了一种模具斜顶机构，其通过在倾斜方向上顶出产品，以使得产品的倒扣结构有效地与模具分离，实现对具有倒扣结构的产品的脱模。该模具斜顶机构的斜顶结构分为两节，其中一节能够打直即竖直设置，从而能够有效地解决空间占用大，斜顶根部易相互干涉或与其他部件易产生干涉的问题。
请一并参阅图1和图2，本申请实施例提供的模具斜顶机构包括直顶件10、第一导向件20、第二导向件30、斜顶件40和柔性推顶件。第一导向件20是竖直设置的，通过其一端可滑动地设于直顶件10上且另一端与第二导向件30连接。第二导向件30设于第一导向件20与斜顶件之间。斜顶件40可滑动地设于第二导向件30的远离第一导向件20的一端上。直顶件10是可移动的，第二导向件30的位置是固定的。柔性推顶件的两端分别与直顶件10和斜顶件40连接，第一导向件20上设有为柔性推顶件提供稳定滑动路径的第一导 向滑轨21，第二导向件30上设有为柔性推顶件提供稳定滑动路径的第二导向滑轨31，第一导向滑轨21和第二导向滑轨31连通。
对于上述设置，第二导向件30的位置是固定的，第一导向件20以与第二导向件30呈一定夹角的方式连接于第二导向件30，也即，第一导向件20和第二导向件30不在一条直线上。第一导向件20的位置也是固定的。当直顶件10上顶时，直顶件10相对第二导向件30滑动，由此带动柔性推顶件沿第二导向滑轨31滑动，之后直顶件10继续沿第一导向滑轨21移动，进而推动斜顶件40移动，斜顶件40远离第二导向件30的端部为斜顶块，或斜顶件40远离第二导向件30的端部连接有斜顶块，斜顶件40在倾斜方向上移动以产生与产品倒扣结构分离的脱模效果。
直顶件10与斜顶件40之间通过柔性推顶件连接，柔性推顶件将直顶件10的直顶动力进行柔性换向以将该动力传动至斜顶件40，进而将直顶件10在竖直方向的动作转换为斜顶件40在倾斜方向上顶出的动作。柔性推顶件通过第一导向滑轨21和第二导向滑轨31的导向而具有稳定的滑动方向，保证其动力柔性传动的有效性，同时第一导向滑轨21和第二导向滑轨31通过对柔性推顶件的导向还能够有效地防止斜顶机构发生顶出卡死的问题。
第一导向件20与第二导向件30(进而斜顶件40)形成模具斜顶机构的分立的两节，使得能够将斜顶机构的下部做直，也就是能够将第一导向件20沿竖直方向设置，第二导向件30能够相对于第一导向件20倾斜设置，从而避免模具斜顶机构占用空间大的问题。
直顶件10为动力部件，或连接有动力部件，动力部件可以为能够做往复直线运动的机构，可以为但不限于为直线电机、气缸、油缸，电机齿轮齿条机构、电机滚珠丝杠机构、电机凸轮机构。在本公开的实施例中，示例性地示出直顶件10上连接的动力部件为油缸(未示出)，油缸具有体积小、动力强劲、工作声噪小的优点。当动力部件上顶直顶件10时，通过柔性推顶件的传动，将斜顶件40顶出，从而实现斜顶触摸；当动力部件下拉直顶件10时，通过柔性推顶件的传动，重新将斜顶件40拉回复位。
可选地，第一导向滑轨21为沿第一导向件20进行滑动的方向设置的平直滑轨，第二导向滑轨31为沿第二导向件30进行滑动的方向设置的平直滑轨。由此，通过第一导向滑轨21和第二导向滑轨31为柔性推顶件在第一导向件20和第二导向件30中提供了平直的移动路径，保证当直顶件10推顶柔性推顶件移动时，柔性推顶件具有较高的移动效率。直顶件10的移动量与柔性推顶件的移动量相等。
可选地，第二导向件30上还设有用于为斜顶件40导向的第三导向滑轨32，第三导向滑轨32与第二导向滑轨31的延伸方向相同，也就是说，第三导向滑轨32与第二导向滑轨31平行设置，即斜顶件40相对于第二导向件30的滑动方向与柔性推顶件在第二导向件30中的滑动方向相同。由此，柔性推顶件对斜顶件40的推顶与斜顶件40的伸出在一个方向 上，从而使得柔性推顶件的推顶力全都施加在斜顶件40上，提升力的传动效率，且柔性推顶件对斜顶件40的推动力不存在其他方向的分力，能够有效地防止斜顶件40的滑动卡死。
请进一步参阅图3和图4，第一导向滑轨21、第二导向滑轨31和第三导向滑轨32的设置方式，使得直顶件10与斜顶件40的移动量相等。也就是说，弯折状的模具斜顶机构的折弯角度保持不变，竖直段和倾斜段的相对弯折部位发生变化，即随着直顶件10的上顶，竖直段减小，倾斜段增大。由于第一导向件20和第二导向件30的连接处为模具斜顶机构的折弯部位，其位置固定，因此竖直段减小的部分由直顶件10上移而形成，倾斜段增大的部分，由斜顶件40伸出而形成。
在本公开的实施例中，可选地，柔性推顶件为传动链50，传动链50具有在一个平面能够发生弯曲，而在其他的平面内不能弯曲和压缩的特性，进而能够有效地保证其既能够弯曲换向，又能够提供有效的传动力，将直顶件10的动力有效地传输至斜顶件40上。
如图5所示，传动链50包括链节51、链板52和固定部53，相邻的链节51通过销轴55和链板52相连接，且固定部53连接在销轴55上以将链板52可转动地与销轴55连接。销轴55可移动地设于第一导向滑轨21和第二导向滑轨31中。
每一链节51上设置有销轴55，链板52上设有两个通孔，每一销轴55上设有环形凹槽，固定部53可以为卡簧，销轴55插入于链板52的一个通孔中，而后使卡簧连接在该销轴55上的环形凹槽中，从而将链板52连接在链节51上，进而在相邻链接51上的销轴55以类似的方式插入于链板52的另一个通孔中并且与卡簧连接之后，相邻的两个链节51通过链板52形成连接。相邻的链节51之间通过链板52形成可转动的连接，固定部53连接在销轴55上从而使得链板52与链节51之间的相对位置固定，进而使得相邻的链节51与链板52形成连接。多节链节51以类似方式进行连接后形成了传动链50，且相邻的链节51之间是可转动的。传动链50的链节51能够以销轴55为轴转动，在其他方向则不能相互转动，由此能够保证传动链50的定向传动效果。
销轴55为在链节51的相对两侧的凸起结构。当链节51上的凸起结构嵌入至第一导向滑轨21中时，第一导向滑轨21能够对销轴55形成限位导向，从而限制销轴55沿第一导向滑轨21中移动。由于第一导向滑轨21具有特定的形态，由此能够限定传动链50以特定的形态沿第一导向件20移动。当链节51上的凸起结构嵌入至第二导向滑轨31中时，第二导向滑轨31能够对销轴55形成限位导向，从而限制销轴55沿第二导向滑轨31中移动，由于第二导向滑轨31具有特定的形态，由此能够限定传动链50以特定的形态沿第二导向件30移动，进而使得传动链50具有稳定柔性传递效果。
在本公开的实施例中，可选地，传动链50还可以包括夹设于链板52与固定部53之间的滚动部54，第一导向滑轨21和第二导向滑轨31与滚动部54相匹配。由此传动链50通 过滚动部54与第一导向滑轨21和第二导向滑轨31形成滚动配合，变传动链50与第一导向滑轨21和第二导向滑轨31之间的滑动摩擦为滚动摩擦，有效地降低导向摩擦力，使得传动链50在第一导向件20和第二导向件30中的移动更为顺畅，防止传动链50在移动过程中有卡死的问题产生。
可选地，滚动部54可以为轴承，轴承的内圈与销轴55连接，外圈能够自由转动，从而在与第一导向滑轨21和第二导向滑轨31配合时形成滚动接触。
如图5所示，可选地，相邻的链节51之间形成斜面凹槽与凸台式的可滑动配合。链节51的双面形成字母扣式的结构，由此能够使得两个链节51依靠相互的卡扣形成斜面配合，传动链50在发生偏转时，通过链节51之间的沿斜面的窜动形成弯折偏转，优化传动链50在推顶方向上的稳定的传动力，当传动链50与第一导向滑轨21和第二导向滑轨31之间有导向结构时，即能够使得前一链节51的推顶力直接施加到后一链节51上，进一步防止传动链50在第一导向件20和第二导向件30中滑动时由于链节51自身偏转而产生摩擦力过大而卡死的现象产生。
在本公开的实施例中，第一导向滑轨21和第二导向滑轨31分别与柔性推顶件形成了凹槽与凸台式的滑动配合，传动链50的链节51的相反两侧的滚动部54作为凸台，第一导向滑轨21和第二导向滑轨31中形成有与该凸台相配合的凹槽。
在本公开的实施例中，可选地，还可以在第一导向滑轨21和第二导向滑轨31设置凸台，在柔性推顶件上设置与该凸台相配合的凹槽。
在本公开的实施例中，可选地，第一导向滑轨21和第二导向滑轨31的横截面与柔性推顶件的横截面相匹配，从而使得柔性推顶件在第一导向滑轨21和第二导向滑轨31中具有稳定的形态，能够保证柔性推顶件在第一导向滑轨21和第二导向滑轨31中的稳定移动。如柔性推顶件为柔索/钢丝绳，其在径向具有可变形的能力，在轴向上的较难被压缩，因此，当第一导向滑轨21和第二导向滑轨31将柔性推顶件的路径限定后，通过直顶件10的推顶能够使得柔性推顶件沿着其轴向移动，对斜顶件40形成有效的推顶。
如图6所示，在本公开的实施例中，可选地，第一导向件20包括将传动链50夹设于其中的两个刚性夹板20a，两个刚性夹板20a上分别设有第一导向滑轨21，两个刚性夹板20a的一端连接在第二导向件30上，另一端能够相对直顶件10滑动。设置第一导向件20的目的主要在于为柔性推顶件形成导向，使得柔性推顶件在第一导向件20中以特定的形态传动，也就是为柔性推顶件在第一导向滑轨21中滑动的这一段赋予刚度。
由于第二导向件30的位置不变，第一导向件20的位置也不变。柔性推顶件，也就是传动链50的一个端部连接在直顶件10上，直顶件10上设有容许第一导向件20，也就是两个刚性夹板20a穿插的插槽11。当直顶件10上顶时，刚性夹板20a位置不变，因此相对 直顶件10下滑，直顶件10使柔性推顶件继续向第二导向滑轨31中移动，从而将斜顶件40顶出。
在本公开的实施例中，可选地，第二导向件30呈套筒状，斜顶件40的一端插设于第二导向件30中，第二导向件30沿轴向相对地设置了两个第二导向滑轨31，并且第三导向滑轨32与第二导向滑轨31平行。
进一步地，第三导向滑轨32的位置与第二导向滑轨31具有90°相位差，也就是说，第三导向滑轨32和两个第二导向滑轨31在第二导向件30中呈十字形分布。
斜顶件40可以只具有与第三导向滑轨32相配合的结构，也可以同时具有与第二导向滑轨31和第三导向滑轨32均配合的结构，还可以省去与第三导向滑轨32相配合的结构而具有与第二导向滑轨31相配合的结构。
进一步地，第二导向滑轨31和第三导向滑轨32为呈十字分布的凹槽，斜顶件40上具有与十字分布的凹槽相配合的十字形凸台。为了避免斜顶件40与第二导向滑轨31之间的配合影响到柔性推顶件与第二导向滑轨31的配合，可选地，将斜顶件40上的凸台与第二导向滑轨31形成间隙配合，由插入至第三导向滑轨32中的凸台形成导向作用。由于斜顶件40通过与第二导向件30上的第三导向滑轨32的配合，使得斜顶件40与第二导向件30还形成了非回转的滑动配合，能够有效地防止斜顶件40发生转动，使得斜顶件40具有优良的斜顶效果。
若在模具斜顶机构的初始位置，即直顶件10位于其下推的极限位置时，传动链50同时位于第一导向滑轨21和第二导向滑轨31中，由于传动链50在第二导向滑轨31中的一段可以看作为具有刚性，无需使得斜顶件40与柔性推顶件之间形成可转动连接。
若在模具斜顶结构的初始位置时，传动链50位于第一导向滑轨21和第二导向滑轨31的交界处，则斜顶件40与柔性推顶件之间形成可转动连接，该转轴与传动链50的销轴55平行，由此能够解除斜顶件40对于柔性推顶件弯折所产生的限制，使得柔性推顶件能够自如地进行转动。
在本公开的实施例中，直顶件10位于下推极限位置时，柔性推顶件同时位于第一导向滑轨21和第二导向滑轨31中。由此在直顶件10上推时，柔性推顶件能够平顺地继续由第一导向滑轨21向第二导向滑轨31中滑动。
本公开的实施例的模具斜顶机构具有例如如下技术效果：
1.第一导向件20的打直设置，有利于节省了空间，解决了小模具中空间位置不足以做正常斜顶的问题。
2.通过导向结构的设置，为柔性推顶件在其中的移动赋予刚度，保证柔性推顶件的力 传动的有效性，防止柔性推顶件在传动过程中发生卡死。
3.采用传动链50作为柔性推顶件具有稳定高效的传动效果，不会发生斜顶卡死的现象。
4.传动链50可以承受较大的扭力，能够有效地避免斜顶折断的问题产生。
5.传动链50的链节51之间通过斜面配合，进一步能够保证传动链50在推顶方向上的刚度，使其既能够通过沿斜面窜动换位，又能够在推顶方向上具有优异的传递效果。
