    • Two trucks are caused to move in side-by-side relation on a pair of parallel tracks, one truck carrying top and bottom mould parts pivoted on opposite sides of the truck and having followers remote from the respective pivot axes. The other truck carries a horizontal support member pivoted on one side of this truck coaxial with the pivot axis of the bottom mould part on the first truck. The support member also has a follower remote from its pivot axis and which is spaced from it by the same amount as is the spacing between the follower of the bottom mould part and its pivot axis. As the truck moves along, the follower of the top mould part engages a carriage movable along an arcuate track having its center of curvature on the pivot axis of the top mould part and which carries the top mould part to an upright position. Thereafter the follower of the top mould part enters a fixed guide which holds it in the upright position. Beyond this is a second arcuate track stradding the paths of the trucks and having its center of curvature coincidental with the pivot axes of the bottom mould part and the support member. A carriage on this second track first engages the follower of the support member to swing it over onto the bottom mould part and then to pick up the follower of the bottom mould part as well and, during its return movement, to swing both the bottom mould part and the support member onto the other truck to transfer a moulded article onto the support member of such other truck. A further arcuate track and carriage then return the bottom mould part back onto the first truck, and a still further arcuate track and carriage then returns the top mould part onto the bottom mould part.
    • 使两个卡车在一对平行的轨道上并排移动,一个卡车承载顶部和底部模具部件,其在卡车的相对侧枢转并且具有远离相应枢轴的从动件。 另一个卡车承载在该卡车的一侧上枢转的水平支撑构件,其与第一卡车上的底部模具部件的枢转轴线同轴。 支撑构件还具有远离其枢转轴线的跟随器,其与底部模具部件的从动件与其枢转轴线之间的间隔与其间隔开相同的量。 当卡车移动时,顶部模具部件的从动件接合可沿着弓形轨道运动的托架,该托架具有在顶部模具部件的枢转轴线上的曲率中心,并将顶部模具部件运送到直立位置。 此后,顶模部件的从动件进入将其保持在直立位置的固定导向件。 除此之外,还有一个第二个弧形轨道,其包括卡车的路径,并且其中心的曲率与底部模具部分和支撑构件的枢转轴线重合。 在该第二轨道上的滑架首先接合支撑构件的从动件以将其摆动到底部模具部件上,然后从底部模具部件的跟随器中拾取,并且在其返回运动期间使两个底部模具 部分和支撑构件放置在另一个卡车上以将模制品转移到这种其他卡车的支撑构件上。 另一个弧形轨道和托架然后将底部模具部分返回到第一辆卡车上,而另一个弓形轨道和托架然后使顶部模具部件返回到底部模具部件上。

    • The method and apparatus for automatically forming a hot top bottom ring from a slurry containing a major portion of granular refractory material, minor portions of inorganic fibrous material and porous refractory material and a resinous binder. The apparatus includes a reservoir containing the slurry, a mold assembly, and a transfer mechanism for moving the mold assembly into and out of the slurry in the reservoir. The mold assembly includes an upper mold member and a lower mold member, the lower member being mounted for movement into engagement with and away from the upper mold member, and a vacuum system operatively connected to the mold assembly to draw the slurry from the reservoir into the mold assembly and to dewater the slurry during the movement of the mold assembly to a dryer screen. The fibrous bottom ring formed in the mold assembly is removed therefrom by the application of air under pressure to deposit the bottom ring on the dryer screen.
    • 用于从含有主要部分的粒状耐火材料的浆料,无机纤维材料的少量部分和多孔耐火材料以及树脂粘合剂自动形成热的顶部底部环的方法和装置。 该装置包括容纳浆料的储存器,模具组件和用于将模具组件移入和移出储存器中的浆料的转移机构。 模具组件包括上模具构件和下模具构件,下构件安装成用于与上模具构件接合并远离上模具构件;以及真空系统,其可操作地连接到模具组件,以将淤浆从储存器中抽出 模具组件并且在模具组件移动到干衣机筛网期间使浆料脱水。 通过在压力下施加空气将形成在模具组件中的纤维底环从其中移除,以将底环沉积在干燥器丝网上。
