In the production of deep cavity pulp molding products, there are different degrees of molding, which affect the product qual⁃ity and reduce the rate of finished products. In this paper, through the analysis of product waste sampling statistics, two kinds of product defects, such as the universal existence of the bottom of the screen printing and edge soft, thin, etc. Design a device that makes use of a floating block to make the same level of the liquid level in the product type surface, thereby effectively solving the defects of the product forming. Product qualification rate from the original about 90%to 98%quickly to ensure product quality.%注浆成型生产深腔类纸浆模塑产品时，均存在不同程度的成型不均匀问题，影响了产品质量，降低了成品率。通过产品废品抽样统计分析，针对普遍存在的底部网印和边沿软、薄等两种产品缺陷进行研究攻关。设计一种巧妙简易的装置，利用占位浮块使得沿产品型面的成型浆料液位基本一致，从而有效地解决产品成型不均匀的缺陷。产品合格率从原来约90%迅速提升到了98%以上，确保产品质量。
