According to the common use of slope protection mold, there are water conservancy slope protection mold, high-speed slope protection mold, railway slope protection mold; according to the production is divided into, cement slope protection mold, plastic slope protection mold. In terms of distribution, the production of slope protection mold mainly includes coastal areas. Because of its high precision, good surface quality and low surface roughness,

零件加工工艺复杂，加工周期长。 模具零件加工包括毛坯切割、锻造、粗加工、半精加工、精加工等工序，还需要进行热处理、表面处理、检验等工序。
The processing technology of parts is complex and the processing cycle is long. Die parts processing includes blank cutting, forging, rough machining, semi finishing, finishing and other processes, as well as heat treatment, surface treatment, inspection and other processes.

护坡模盒加工精度主要体现在两个方面: 一是模具零件本身的高精度，二是相关零件的高精度。The machining accuracy of slope protection mould is mainly reflected in two aspects: one is the high precision of mold parts themselves, the other is the high precision of related parts.

在模具加工中，为了降低模具加工的难度，经常采用匹配加工的方法，即在加工过程中，允许某些零件的基本尺寸稍大或稍小，但是与之匹配的零件也必须相应地增大或减小，从而降低了模具加工的难度。 不仅可以保证模具的质量，还可以避免不必要的零件报废。

In mold processing, in order to reduce the difficulty of mold processing, the method of matching processing is often used, that is, in the process of processing, the basic size of some parts is allowed to be slightly larger or smaller, but the matching parts must also be increased or reduced accordingly, so as to reduce the difficulty of mold processing. It can not only ensure the quality of the mold, but also avoid unnecessary parts scrapping.
