摘要
通过分析瓶盖的结构特征,设计一模二腔热流道注射模具,瓶盖分段内螺纹特征利用内斜顶模具结构成型。模具设计结构合理,开、合模动作可靠,制品脱模顺利,塑件精度高,产品能够完全达到客户要求。
By analyzing the structural characteristics of the bottle cap, an injection mould with two-cavity and hot runner was designed. The feature of the segmented internal screw for bottle cap was formed by the mould structure of internal inclined roof. The designed mould structure is reasonable, the opening and closing action is reliable, the demoulding of the product is smooth, the plastic parts have high precision, and the products completely meet the customer’s requirements.
