摘要： A foundry molding machine utilizing a match-plate and two sets of rubber lined cope and drag slip flasks with two stations; one station assembling one set of flasks with the match-plate therebetween and then rolling over the flask-match-plate assembly to fill the drag with sand while supporting the assembly on the cope and jolting and applying a low pressure preliminary squeeze to the sand within the drag, rolling the assembly back to fill the cope and then supporting the assembly on the sand within the drag for the application of jolt and high pressure squeeze to the sand in both the cope and drag, separating the assembly and indexing the cope and drag vertically separated to a second station while simultaneously indexing the second set of flasks to the first station, holding the sand rammed flasks vertically separated in the other station to permit coring and closing the flasks and stripping the sand cakes thus assembled therefrom to be placed on a bottom board while the second set of flasks are being filled and rammed at the first station; the indexing and roll-over of such flasks being obtained each by a piston-cylinder assembly having controlled stroke deceleration on extension thereof.
摘要翻译：采用匹配板的铸造成型机和两台带有两个台站的橡胶衬里和拖滑板; 一个站组装一组烧瓶，其间具有匹配板，然后在烧瓶配合板组件上滚动以用沙子填充阻力，同时将组件支撑在上下和颠簸上，并将低压初步挤压施加到砂内拖曳，将组件滚动以填充对面，然后在拖曳状态下将组件支撑在沙上，以便在上下和下拖曳中施加颠簸和高压挤压到沙子上，分离组件并分配上下料和拖曳垂直分隔到第二工位，同时将第二组烧瓶分配到第一工位，将砂夯锤在另一工位上垂直分隔，以允许取芯和关闭烧瓶并剥离由此组装的砂饼放置在底板，而第二组烧瓶正在第一站被填充和撞击; 这种烧瓶的分度和翻转是通过活塞 - 气缸组件获得的，该活塞 - 气缸组件在其延伸上具有受到控制的行程减速度。

摘要： A matchplate foundry molding machine having a fill station and an adjacent molding station with a cope, matchplate, and drag assembly adapted to be indexed between such stations. The assembly in the fill station is supported for inversion so that the drag may be inverted and filled with sand. After a bottom board is inserted the assembly is reinverted and the cope filled with sand. The assembly is then indexed into the molding station which includes a vertically movable table, a drag support, a cope support, a fixed matchplate support, and a squeeze head incorporating a jolt ram. When the sand filled assembly is in position, the table elevates and simultaneously jolts and squeezes the cope and drag. The table is then lowered to draw the matchplate from the cope which is held against the squeeze board by its support and when the drag and matchplate reach the matchplate support, the matchplate is drawn from the drag with the drag continuing to coring height with the matchplate alone now indexing back to the fill station. The drag support then elevates the drag with the table following to close the drag against the cope, slight further elevation lifting the flasks free of the sand cakes held by the squeeze head which are then supported on the table. The table lowers with the booked cope and drag sand cakes thereon, the drag support following with the drag, with the cope remaining elevated. When the drag is clear, the matchplate is again indexed into the molding station to be reassembled with the cope and drag flasks. The assembly is then indexed to the fill station for filling and the booked sand cakes are pushed out of the machine.
摘要翻译：一种具有填充站和相邻成型站的圆盘铸造模制机，其具有适于在这些工位之间进行索引的上模，匹配板和拖曳组件。填充站中的组件被支撑用于反转，使得阻力可以倒置并且填充砂。在插入底板后，组件被重新启动，并且上盖板上充满了沙子。组件然后被分配到模制站中，该模制站包括可垂直移动的工作台，拖曳支撑件，上模支撑件，固定的搭配板支撑件和结合有冲击柱塞的挤压头。当填沙装置就位时，桌子升起并同时颠簸并挤压上下车并拖动。然后将桌子放下，以便从保持在挤压板上的托盘上拉出匹配板，当拖板和匹配板到达匹配板支架时，匹配板从拖曳中拉出，拖曳与砧座连续到取芯高度单独现在索引到填充站。然后，拖曳支撑件随着桌子跟随而提升拖曳以关闭对着上颚的拖曳，稍微进一步升高提升烧瓶没有被挤压头保持的砂饼，然后支撑在桌子上。桌子下降了预订的面包，并在其上拖曳砂饼，拖曳后跟随拖曳，保持高空。当拖曳清除时，匹配板再次被索引到成型台中，以与上盖和下砂箱重新组装。然后将组件索引到填充站以进行填充，并将预定的砂饼推出机器。
