    摘要： A furnace assembly for dewaxing investment casting molds includes a housing having a top and a bottom and sides and extends along an axis to define a cavity. A plurality of tiles are supported in a spaced relationship with the bottom of the housing and define a pair of lower chambers for directing the wax vapors out of the cavity. A plurality of trays having apertures are supported by the tiles for moving molds through the housing. Chimneys connect to the lower chambers and a passageway is defined by the tiles for evacuating the wax and wax vapors from the cavity to the lower chambers and out through the chimneys. A pair of lower burners extends into the lower chambers for igniting wax vapors in said lower chambers. The heat from the lower chambers radiantly heats up portions of the furnace assembly that are disposed above the lower chambers.

    摘要： A shell molding apparatus includes a lower die and an upper die. The lower die includes a plurality of shell molding inserts, each having the shape of a halved cylinder, spiny insert receiving recesses which are formed in undercut portions formed by curved surfaces of adjacent shell molding inserts, and spiny inserts retractably provided in the spiny insert receiving recesses, each spiny insert having a curved surface of the same curvature as the curved surface of the shell molding insert and provided with many protrusions on the curved surface. The upper die has a plurality of continuously formed recesses corresponding to the plurality of shell molding inserts of the lower die. The shell molding apparatus further includes a spiny insert actuating mechanism for projecting/retracting spiny inserts by operating withdrawal pins connected to the spiny inserts, a stopper mechanism for positioning the withdrawal pins at a position where the withdrawal pins exhibit the same thermal expansion, and a thermal expansion absorbing mechanism for the withdrawal pins. The shell molding apparatus further includes a sand releasing mechanism for preventing shell sand from stagnating between spiny insert receiving recesses and the spiny inserts, resulting in smooth performance of the spiny inserts.

    摘要翻译： 壳体成型装置包括下模和上模。 下模具包括多个壳体模制插入件，每个壳体模制插入件具有半圆柱形的形状，多个插入件容纳凹槽，其形成在由相邻的外壳模制插入件的弯曲表面形成的底切部分中，以及可旋转地设置在多刺插入件 凹槽，每个多刺插入物具有与壳模制插件的弯曲表面相同曲率的曲面，并且在弯曲表面上设置有许多突起。 上模具具有多个连续形成的与下模的多个外壳模制插件对应的凹槽。 外壳成型装置还包括用于通过连接到多刺插入件的操作提取销来突出/缩回多刺插入件的多刺插入致动机构，用于将取出销定位在提升销呈现相同热膨胀的位置的止动机构，以及 退火针的热膨胀吸收机构。 外壳成型设备还包括一个防砂壳，用于防止壳砂停滞在多刺插入物容纳凹槽和多刺插入物之间，从而使多刺插入物的平滑性能得以实现。

    摘要： An automatic no-bake core and mold-making machine. A frame is rotatably mounted on a base and carries a plurality of core-forming patterns around its periphery. Plates surround the patterns to form a continuous, flat surface interrupted only by the pattern cavity. A mixing machine located adjacent to the rotating frame continuously pours sand and binder on the patterns and surrounding plates. A stationary plow under which the plates and patterns pass continuously wipes excess sand and binder into the next succeeding pattern passing below the plow. Means are provided for ejecting the cores from the patterns after they are cured.
