摘　　要：针对塑件在模内装饰成型要求,设计了1副1模1腔两板注射模用于膜片的预成型,模具使用热喷嘴+普通流道以缩短流道长度,使用10条水路对型腔板均衡冷却,降低了收缩变形对膜片成型形状的影响;使用镶件成型筋位,并采用推块实现脱模;侧壁内孔使用斜推块实施侧抽芯,外壁倒扣使用斜导柱滑块机构实施侧抽芯。In view of the moulding requirements of in-mould decoration for plastic parts,a two plate injection mould with one cavity was designed for preforming the mebrane.The hot nozzle+ordinary runner was used to shorten the length of the runner,and nine waterways were used for balanced cooling the cavity,which reduced the influence of shrinkage deformation on the shape of the mebrane.The inserts were used to form the stiffeners,and the ejector pad was used for demoulding.For the inner hole of the side wall,inclined ejector pad was used for side core-pulling,and inclined guide pillar slider mechanism was used for side core-pulling the under cut on the outer wall.
