Considered the third phase of the Injection Molding Cycle, the Cooling Phase consumes the greatest amount of time. Therefore, it is a serious area for designers and mold makers to make sure that all Coolant schemes have been thoroughly investigated for their suitability.

Slide Action requires several mechanical components to enable the molding of complex part geometry.   Slides are usually used for exterior action, and typically pull a core located on the "B" side of the mold.
 

一、设计依据
尺寸精度与其相关尺寸的正确性。
根据塑胶制品的整个产品上的具体要和功能来确定其外面质量和具体尺寸属于哪一种：
外观质量要求较高，尺寸精度要求较低的塑胶制品，如玩具；
功能性塑胶制品，尺寸要求严格；
外观与尺寸都要求很严的塑胶制品，如照相机。
脱模斜度是否合理。
脱模斜度直接关系到塑胶制品的脱模和质量，即关系到注射过程中，注射是否能顺利进行：
脱模斜度有足够；
斜度要与塑胶制品在成型的分模或分模面相适应；是否会影响外观和壁厚尺寸的精度；

Mold or die are the common terms used to describe the tooling used to produce plastic parts in molding.

Traditionally, molds have been expensive to manufacture. They were usually only used in mass production where thousands of parts were being produced. Molds are typically constructed from hardened steel, pre-hardened steel, aluminium, and/or beryllium-copper alloy. The choice of material to build a mold from is primarily one of economics, steel molds generally cost more to construct, but their longer lifespan will offset the higher initial cost over a higher number of parts made before wearing out. Pre-hardened steel molds are less wear resistant and are used for lower volume requirements or larger components. The steel hardness is typically 38-45 on the Rockwell-C scale. Hardened steel molds are heat treated after machining. These are by far the superior in terms of wear resistance and lifespan. Typical hardness ranges between 50 and 60 Rockwell-C (HRC). Aluminium molds can cost substantially less, and when designed and machined with modern computerized equipment, can be economical for molding tens or even hundreds of thousands of parts. Beryllium copper is used in areas of the mold which require fast heat removal or areas that see the most shear heat generated.The molds can be manufactured by either CNC machining or by using Electrical Discharge Machining processes

Injection molding (British English: moulding) is a manufacturing process for producing parts from both thermoplastic and thermosetting plastic materials. Material is fed into a heated barrel, mixed, and forced into a mold cavity where it cools and hardens to the configuration of the mold cavity.  After a product is designed, usually by an industrial designer or an engineer, molds are made by a moldmaker (or toolmaker) from metal, usually either steel or aluminium, and precision-machined to form the features of the desired part. Injection molding is widely used for manufacturing a variety of parts, from the smallest component to entire body panels of cars.
