Lower flow channel plate mold structure used for automobile vibration absorption equipment

一种用于汽车减震设备的下流道板模具结构

Abstract

The utility model relates to a lower flow channel plate mold structure used for automobile vibration absorption equipment. The lower flow channel plate mold structure is characterized in that a sprue sleeve is arranged on the inner side wall of a fixed mold frame; the sprue sleeve is communicated with a fixed mold core; a movable mold core is internally provided with pouring cavities which are symmetrical up and down and are in a square structure; one group of cinder ladles are arranged at the edge of the upper side of each pouring cavity; the cinder ladles are connected with an exhausting groove and an exhausting channel; a kidney-shaped through hole is formed in the middle part of each pouring cavity and one circle of a columnar convex strip is arranged on the inner wall of each pouring cavity; a triangular groove is formed in the front and tail connection part of each columnar convex strip. According to the lower flow channel plate mold structure, the pressure of aluminum liquid is increased again and the aluminum liquid is ejected out, so that the aluminum liquid can fully fill the cavity in extremely short time and a high-quality product is cast; the outer side of each pouring cavity is connected with the corresponding cinder ladle and exhausting groove, so that the exhausting is more effective, air holes of the product are reduced and the quality of the mold is improved.
本实用新型涉及一种用于汽车减震设备的下流道板模具结构,其特征为:定模框的内侧壁设有一浇口套,所述的浇口套与定模芯相连通,动模芯内设有上下对称的方形结构浇注型腔,浇注型腔的上侧边缘设有一组渣包,渣包与排气槽、排气通道相连,浇注型腔中部设有一腰状槽孔,沿浇注型腔内壁设有一圈柱状凸条,柱状凸条的首尾相接处设有形成一三角形凹槽。这些设置使得铝液在此再次增加压力并且高速冲出,使得铝液在极短时间内充填型腔,铸造出高品质的产品,每个浇注型腔的外侧均连接渣包和排气槽,使得排气更为有效,减少产品的气孔,提高了模具的质量。
