Perspective window molding process and design of injection mold
Abstract：In order to complete the general perspective window injection mold design the general perspective windows process characteristics and process requirements, and describes the mold working principle. The design for the plastic see-through window mold making design using CAD/CAM technology and UG/NX product design. Use vernier caliper mapping the shape of the parts, and three-dimensional shape of the product based on mapping results using the UG/NX software parts, and then determine the parting surface, gating system. This design uses the DC Road side of the gate, putting Release institutions. It introduced the system design process in the mold of the plastic see-through window; entire mold assembly and use; injection mold structure and related computational problems are elaborated. In the mold design, using computer CAD drawing software to draw the part and assembly drawings .The design, taking into account the size of the parts and precision requirements, reasonable arrangements for the order of processing of each part, to ensure the production of qualified parts from the mold material is selected departure. As far as possible to minimize production costs, increase productivity at the same time.

1引言
模具是工业生产的重要装备，是国民经济的基础设备，是衡量一个国家和地区工业水平的重要标志。模具在电子、汽车、电机、电器、仪器仪表、家电和通讯产品制造中具有不可替代的作用，是工业发展的基石，被人称为“工业之母”和“磁力工业”。
模具是制造业的重要基础装备，是工业化国家实现产品批量生产和新产品研发所不可缺少的工具。用模具生产制品所表现出来的高效率、低消耗、高一致性、高精度和高复杂程度是其他任何制造方法所不及的。换句话说，没有高水平的模具就不会有高水平的工业产品。模具业是否强盛也反映出一个国家工业的强弱。
