周转箱塑件的滑块内置斜顶复合式抽芯注射模具设计
Design of Injection Mold of Sliding Block with Built-in Inclined top Composite Core Pulling of Turnover Box Plastic Parts
摘要
Abstract
Based on the shape characteristics and production needs of plastic turnover boxes,a two plate injection mold structure with one mold and one cavity was designed.In response to the difficulties in demolding multiple detailed features of plastic parts and the limitations of mold space distance,a four side sliding block demolding mechanism was set up.For the detailed features of plastic parts that cannot be completed by conventional side core pulling or inclined top mechanisms,an innovative design of a composite hydraulic core pulling mechanism with three irregular inclined tops embedded in the same sliding block was proposed.A composite cooling system similar to the"conformal water circuit"has been applied,with a diameter of 6 mm for the cooling water circuit of the dynamic and fixed mold inserts,and independent cooling water circuits with a diameter of 11 mm designed for all four sliding blocks.The cooling effect was significant and the molding cycle was shortened.The guiding positioning system used a precise positioning method similar to the dynamic mold stopper and the fixed mold stopper to ensure accurate and stable resetting of the mold during the opening and closing process.A separate slider track was designed to improve the strength of the dynamic template and save mold materials.In addition,in order to avoid deformation during product ejection and simplify the mold structure,four sets of"ejector rods+L-shaped ejector blocks"were designed to ensure smooth ejection of the product.The design essentials of other mold systems were analyzed in detail.It has been proven through practice that the mold structure is designed reasonably,operates smoothly,and the indicators of the molded products meet the requirements,which can provide a beneficial reference for the mold design of similar products.关键词
