摘　　要：根据咖啡壶嘴塑件的结构特点和要求,模具设计采用动模和定模的对接形式所构成的分型面与塑件轮廊形状相一致的结构,利用油缸液压抽芯成型外侧侧凹,通过固定型芯的“T”形槽带动活动型芯完成内抽芯,以推块作顶出装置。模具结构紧凑合理,容易加工制造。采用侧浇口内侧进料的方式,可以有效改善塑件的外观质量。Based on the structural characteristics and requirements of the coffeepot spout,the mold adopts the form of the movable mold and the fixed mold to form a coherent parting surface and contour shape of the plastic part.The outer side concave is formed by the hydraulic core pulling of the cylinder;side core-pulling is completed by T-shaped groove driving the active core and push block as the ejector device.The structure is compact and reasona-ble,easy to manufacture.The use of side gate inside feed can effectively improve the appearance of the quality of plastic parts.
