设计塑料模具需求思索哪些构造要素
What Constructive Elements Should Be Considered in Designing Plastic Moulds
塑料模具设计又以正确的塑料制品设计爲根底,模具设计和制造与塑料加工有亲密关系。塑料加工的成败,很大水平上取决于模具设计效果和模具制造质量,明天山东塑料模具厂家就带大家看看需求留意的成绩:
The design of plastic moulds is based on the correct design of plastic products. The design and manufacture of plastic moulds are closely related to plastic processing. The success or failure of plastic processing largely depends on the design effect of the mould and the quality of the mould manufacturing. Tomorrow Shandong plastic mould manufacturers will show you the achievements that need attention:
1、构造件
1. Structural parts
即复杂模具的滑块、斜顶、直顶块等。构造件的设计十分关键,关系到模具的寿命、加工周期、本钱、产质量量等,因而设计复杂模具中心构造对设计者的综合才能要求较高,尽能够追求更简便、更耐用、更经济的设计方案。
That is, slide block, inclined top block and straight top block of complex die. The design of structural parts is very important, which is related to the life, processing cycle, cost, production and quality of the die. Therefore, the design of complex die center structure requires a higher comprehensive ability of the designer, and can pursue a more simple, durable and economical design scheme.
2、分型面
2. Parting surface
即模具闭合时凹模与凸模互相配合的接触外表。它的地位和方式的选定,受制品外形及外观、壁厚、成型办法、后加工工艺、模具类型与构造、脱模办法及成型机构造等要素的影响。
That is, when the die is closed, the contact surface between the die and the punch matches each other. The selection of its position and mode is influenced by the shape and appearance of the product, wall thickness, forming method, post-processing technology, die type and structure, demoulding method and forming mechanism.

3、浇注零碎
3, casting piecemeal
即由注塑机喷嘴至型腔之间的进料通道,包括主流道、分流道、浇口和冷料穴。特别是浇口地位的选定应有利于熔融塑料在良好活动形态下充溢型腔,附在制品上的固态流道和浇口冷料在开模时易于从模具内顶出并予以肃清。
That is, the feeding passage from the injector nozzle to the cavity of the injection moulding machine, including the main passage, the shunt passage, the gate and the cold material hole. In particular, the selection of gate position should be conducive to the filling of molten plastics into the cavity in a good active form, and the solid runner attached to the product and the cooling material of the gate can be easily ejected from the die and cleaned up when opening the die.
4、模具精度
4. Die accuracy
即避卡、精确的地位固定、导柱、地位固定销等。地位固定零碎关系到制品外观质量,模具质量与寿命,依据模具构造不同,选择不同的地位固定方式,地位固定精度控制次要依托加工,内模地位固定次要是设计者充沛去思索,设计出愈加合理易调整的地位固定方式。
That is to say, avoidance of cards, accurate position fixing, guide pillar, position fixing pin, etc. Position fixing is related to product appearance quality, die quality and life. According to different die structure, different position fixing modes are selected. Position fixing accuracy control is secondary to processing. Internal die position fixing is secondary to designer's thinking, and more reasonable and adjustable position fixing modes are designed.
