<p dir="auto">倒扣处理是注塑模具设计中技术含量最高的环节之一。滑块和斜顶是最常用的两种倒扣处理机构。</p>
<h2>滑块（Slider）设计</h2>
<h3>适用场景</h3>
<p dir="auto">外侧倒扣、侧孔、侧凹槽。</p>
<h3>核心参数</h3>
<table class="table table-bordered table-striped">
<thead>
<tr>
<th>参数</th>
<th>推荐值</th>
</tr>
</thead>
<tbody>
<tr>
<td>滑块行程</td>
<td>倒扣深度+3~5mm安全余量</td>
</tr>
<tr>
<td>斜导柱角度</td>
<td>15°~25°</td>
</tr>
<tr>
<td>滑块斜面锁紧角</td>
<td>斜导柱角+2°~3°</td>
</tr>
<tr>
<td>滑块尺寸</td>
<td>宽度≥倒扣宽度的1.5倍</td>
</tr>
</tbody>
</table>
<h3>磨损预防</h3>
<ul>
<li>滑块与模板配合面加淬火磨板</li>
<li>做好润滑槽</li>
<li>滑块底部设耐磨板（铜合金或石墨）</li>
</ul>
<h2>斜顶（Lifter）设计</h2>
<h3>适用场景</h3>
<p dir="auto">内侧倒扣。</p>
<h3>核心参数</h3>
<table class="table table-bordered table-striped">
<thead>
<tr>
<th>参数</th>
<th>推荐值</th>
</tr>
</thead>
<tbody>
<tr>
<td>斜顶角度</td>
<td>5°~12°</td>
</tr>
<tr>
<td>斜顶厚度</td>
<td>≥8mm</td>
</tr>
<tr>
<td>导向段长度</td>
<td>≥斜顶总长的2/3</td>
</tr>
</tbody>
</table>
<h3>常见问题</h3>
<ul>
<li><strong>卡死</strong>→检查角度是否过大，顶出是否顺畅</li>
<li><strong>磨损</strong>→建议渗氮处理或加耐磨涂层</li>
</ul>
