The invention provides a sand mold transfer device. The sand mold transfer device comprises a sand mold supporting part, a sand mold pushing part, a sand paving mechanism and a displacement mechanism. The sand mold supporting part is used for supporting a sand mold, the sand mold pushing part is used for unloading the sand mold from the sand mold supporting part, the sand paving mechanism is used for paving molding sand at the unloading position of the sand mold before the sand mold pushing part unloads the sand mold on the sand mold supporting part, and the sand mold supporting part, the sand mold pushing part and the sand paving mechanism move along with the displacement mechanism; the device has the beneficial effects that by arranging the sand mold supporting part, the sand mold pushing part, the sand paving mechanism and the displacement mechanism, a layer of molding sand can be paved at the sand mold placing place while the sand mold is transported and placed, and the situation that the sand mold is in rigid contact with the ground, and consequently the bottom of the sand mold cracks due to uneven stress is avoided; the transfer device paves the molding sand at the bottom of the sand mold to replace the previous manual sand paving, so that the working efficiency is improved; and the sand paving amount control of the sand paving mechanism is higher than that of manual sand paving, so that the sand paving amounts are basically consistent, and the situation of excessive paving or insufficient paving is avoided.
本发明提供了砂型转运装置,包括砂型托件、砂型推件、铺砂机构以及位移机构;砂型托件用于托起砂型,砂型推件用于将砂型从砂型托件上卸下,铺砂机构用于在砂型推件将砂型托件上的砂型卸下前,在砂型卸下的位置铺上型砂,砂型托件、砂型推件以及铺砂机构随位移机构一同位移;本发明的有益效果:通过设置砂型托件、砂型推件、铺砂机构以及位移机构,使得在将砂型运输、放置的同时,能够在砂型放置地点铺上一层型砂,避免砂型与地面刚性接触,造成砂型底部受力不均匀而裂开;转运装置在砂型底部铺型砂来替代以前的人工铺砂,提高了工作效率,并且铺砂机构对铺砂量的把控高于人工,使得每次铺砂量差不多,且刚好够,不会出现多铺或少铺的情况。
