在 喷射模塑工艺,该模基础是一个重要组成部分的模,作为该框架的整个模式结构。 它是由各种钢板和零件。 但是,许多仅有部分理解其重要的意义。 由于显着差异之间的处理模基地和其他地区的模具、模具制造商,通常选择购买的模基地,从专门化模的基地制造商。 这使得这两个缔约国利用其各自生产的优势,最终提高总体生产的质量和效率。
在简单条款,该模基地主要由预成型设备,定位设备,并且喷射装置。 一个典型的结构中包括顶板、板(前模),B板(回模),C板(支持板)、底板、喷射器的销板,喷射器的销底板,以及成分,如销和引导返回销。

大小的塑料模主要取决于由维和结构的塑料产品。 确保强度的模、结构设计应当尽可能紧凑。 基于产品的外部尺寸(例如预计的面积和高度)及其结构特征(如侧切滑),尺寸的刀片可以确定,允许对一个粗略的估计模基础的大小。

Frame Selection: Matching Mold Structure to Part Geometry
Mold frames are chosen once and lived with for the tool’s life. The matching logic between structure and part:
| Part character | Frame tendency | Why it fits |
|---|---|---|
| Shallow, flat housings | Two-plate, edge-gated | Simple fill path, cheapest maintenance |
| Deep, thin-wall bodies | Three-plate or hot-runner | Gates where fill needs them |
| Complex internal features | Split cores, sliders | Mechanical release for undercuts |
| High-volume small parts | Multi-cavity, balanced runners | Cost per part at rate |
The undercuts row is where budgets break when geometry is reviewed late. Every slider and lifter adds moving steel that wears, leaks and maintains — and a part redesigned early to eliminate two undercuts often pays for the design review in tooling savings alone. The hot-runner row carries its own economics: higher upfront cost in exchange for runner scrap eliminated, a trade that favours volume and penalises short runs, which is why the honest answer to “should this tool be hot-runner?” starts with the production forecast rather than the catalogue. Frame selection done this way — geometry first, forecast second, structure third — produces tools whose maintenance history stays boring, and boring is the compliment that matters in tooling. The structural detail is expanded in custom mold structure explained, and the surface consequence in high-gloss product manufacturing. 。參考: 成型流程 和 injection tooling.
