摘要： When pressing kneaded sand in a kneading sand tank into a mold by a pressing member, a pressing force applied to a kneaded sand layer in the kneading sand tank is monitored and a moving position of the pressing member is monitored from when the pressing member starts to move. A pressing start time (tl) at which the kneaded sand starts to flow into the mold is identified based on the pressing force applied to the kneaded sand layer in the kneading sand tank, and a pressing starting position (L3) of the pressing member at the pressing start time (tl) is identified. As a result, the pressing start time (tl) and the pressing starting position (L3) of the pressing member when the kneaded sand starts to flow into the mold are accurately identified, so the reliability of a filling evaluation of the kneaded sand into the mold is improved.
摘要翻译：当通过挤压构件将捏合沙缸中的捏合的沙子压入模具中时，监测施加到捏合沙缸中的捏合沙层上的压力，并且挤压构件的移动位置是从按压构件开始移动时开始监视。基于施加到捏合砂箱中的捏合砂层的压力以及挤压构件的按压开始位置（L3）来确定捏合砂开始流入模具中的压紧开始时间（t1）确定按下开始时间（t1）。结果，准确地确定了当混砂开始流入模具时按压部件的按压开始时间（t1）和按压开始位置（L3），从而可以将混砂的填充评价的可靠性模具得到改进。

摘要： Provided is a method of producing foamed sand (s) for forming a sand mold. The foamed sand (s) includes sand particles (p) and foam (f) adhering to surfaces of the sand particles (p). The foam (f) contains water glass (b), water (w), and a surfactant (c). According to the method, an aqueous surfactant solution (e) in which the surfactant (c) is dissolved is frothed to generate froth (d) from the aqueous surfactant solution (e). Then, the generated froth (d), the water glass (b), and the water (w) are kneaded with the sand constituted by the sand particles (p).
摘要翻译：提供了一种生产用于形成砂模的发泡砂的方法。发泡砂包括粘附在砂粒（p）表面上的砂粒（p）和泡沫（f）。泡沫（f）含有水玻璃（b），水（w）和表面活性剂（c）。根据该方法，其中溶解有表面活性剂（c）的表面活性剂水溶液（e）发泡以从表面活性剂水溶液（e）产生泡沫（d）。然后，将所产生的泡沫（d），水玻璃（b）和水（w）与由沙粒（p）构成的沙混合。
