Plastic mold structure and classification
The mold base is the mold base: MoldBase.
The mold blank is the skeleton of the entire mold. All mold parts need to consider the structure of the mold blank. The cost of the mold base generally accounts for about 30% of the entire mold. The mold base is manufactured by a special large mold base factory and has been standardized. Each mold manufacturer only needs to customize to the mold base factory according to its own needs. The mold base is divided into a panel, A plate <front template), B plate <rear template), C plate <square iron), bottom plate, thimble panel, thimble bottom plate, cylinder, guide post, return needle, thimble, support head, limit Bit nails and so on.
That is, the molding core embedded in the mold base template. Divided into front mold kernel, rear mold kernel, commonly known as front mold <Cavity), rear mold <Core). Why embed the mold kernel in the template? Mainly to save costs. Because plastic has high requirements on the steel characteristics of the mold, such as hardness, corrosion resistance, high temperature resistance <thermal deformation), etc .; and the template of the mold blank does not need too high requirements.
