摘要： A stationary die for a horizontal die casting machine has an oscillatable molten metal injector below the die that oscillates from an acute angle outside the die for filling with molten metal to an acute angle under the die or injecting the molten metal into the die. The stationary die has an annular docking block at the same acute angle to the horizontal as the axis of the shot sleeve under the die. The edge of the aperture at the outer end of the docking block is adjacent to and substantially in the plane of the parting surface of the stationary die so that the docking block per se projects outwardly from the surface. Correspondingly, the adjacent parting surface of the movable die is provided with a cavity for fitting this projection of the docking block, but since the surfaces of this docking block are at convergent acute angles, they provide no restriction to the movement of the movable die. A trough duct is provided in the stationary die from the open end aperture of the docking block to the die cavity for the molten metal for producing the casting between the closed dies. Ejector pins are provided for removal of the casting after it has been cast and the dies parted. Furthermore, the movable die may be provided with one or more slides, including a slide adjacent the docking block with a cavity therein for receiving the outward projecting part of this block from the surface of the stationary die.
摘要翻译：用于水平压铸机的固定模具具有在模具下方的可摆动的熔融金属注射器，其从模具外部的锐角振荡，以将熔融金属填充到模具下方的锐角或将熔融金属注入模具中。固定模具具有与模具下方的喷射套筒的轴线水平相同锐角的环形对接块。在对接块的外端处的孔的边缘与固定模具的分型表面相邻并且基本上位于平面中，使得对接块本身从表面向外突出。相应地，可移动模具的相邻分型表面设置有用于装配对接块的该突起的空腔，但是由于该对接块的表面处于会聚锐角，所以它们不限制可移动模具的运动。在固定模具中，从对接块的开口端口到用于熔融金属的模腔设置槽管，用于在闭合的模具之间产生铸造。提供推杆用于在铸件铸造之后移除铸件并将模具分开。此外，可移动模具可以设置有一个或多个滑块，包括邻近对接块的滑块，其中具有空腔，用于从固定模具的表面接收该块的向外突出的部分。

摘要： The hollow frusto-conical expendable core is used for forming a jacket around a cylinder in a casting die for forming a cylinder block. The core has a printout portion comprising an inwardly extending annular flange connected to the narrower end of the frusto-cone by circumferentially spaced axially extending legs. The core may comprise a plurality of frusto-cones for a corresponding plurality of cylinders in an engine block with their axes parallel in a common plane with the annular flanges of their printout portions integrally connected for strengthening the multi-cylinder jacket core.

摘要： A method for casting metals around an article having a bore extending along a central axis and defined at least in part by an interior cylindrical wall portion utilizes a mandrel having a cylindrical exterior surface portion sized to be slidingly positioned in said bore in close relationship with said interior cylindrical wall portion. The mandrel has an annular groove in which is positioned a canted coil spring with a series of outer contact points extending radially outwardly beyond said cylindrical exterior surface portion. The article is moved onto the mandrel to compress the spring and deflect the outer contact points such that the spring imparts an outwardly directed force to the article interior cylindrical wall portion to provide frictional resistance between the spring, outer contact points and the interior cylindrical wall portion to retain the article on the mandrel while casting molten metal around the mandrel supported article to form a cast part.

摘要： This disclosure concerns a casting die for a cylinder, including engine blocks having a plurality of cylinders such as for internal combustion engines, including an expendable core for forming a jacket around the cylinders. This core has a printout portion at one end of the cylinder which is held in place by a cooperating flange on a mandrel that fits inside the cylinder. This mandrel may hold a liner for the cylinder. A dowel is provided in one of the die parts for insertion into the hollow mandrel. The mandrel is held in position by being clamped between the two opposing die parts, and the flanges of the core printout portion may be loosely held in the printout cavity of one of the die parts which preferably also contains one or more locating pins for bridging at least part of the gap between the printout portion and the printout cavity in the die for better positioning the core in the die. The core and mandrel may be assembled outside the die before being placed on the dowel, and after the casting is made, the mandrel and core are removed with it and then separated so the mandrel can be reused. For forming plural cylinders in an engine block, a secondary mandrel frame may be employed for further supporting the separate mandrels for each cylinder and the plural cylinder expendable core by holding the flanged printout portion of the core between the flanges on the separate mandrels and the secondary mandrel frame. In casting the plural cylinders of a V-engine block, retractable dowels permit the employment of die parts and slides that move only at right angles to each other.
摘要翻译：本公开涉及一种用于气缸的铸模，其包括具有多个气缸的发动机缸体，例如用于内燃机，包括用于在气缸周围形成护套的消耗性芯。该芯具有在气缸一端的打印输出部分，该打印输出部分通过配合在气缸内的心轴上的配合凸缘保持在适当位置。该心轴可以保持气缸的衬套。在一个模具部件中设置有一个榫钉，用于插入中空心轴。心轴通过夹在两个相对的模具部件之间而保持就位，并且芯部打印输出部分的凸缘可以松动地保持在一个模具部件的打印输出腔中，其优选地还包含一个或多个定位销，用于桥接在模具中打印输出部分和打印输出腔之间的间隙的最小部分，用于更好地将芯体定位在模具中。芯和心轴可以在被放置在榫钉上之前组装在模具外部，并且在铸造之后，心轴和芯体被移除，然后分离，使得心轴可以重复使用。为了在发动机缸体中形成多个气缸，可以采用次级心轴框架来进一步支撑每个气缸和多个气缸消耗性芯的分开的心轴，通过将芯的带凸缘的打印输出部分保持在分离的心轴上的凸缘和次级心轴框架。在铸造V型发动机缸体的多个缸体时，可缩回的销钉允许使用仅以直角相互移动的模具部件和滑块。

摘要： The locating pins have notched ends, each of which simultaneously restricts the movement of an expendable core in two orthogonal directions in a die casting die. A plurality of these pins alone and with other pins project into the space between the printout cavity in a die casting die and the printout portion of an expendable core positioned in that cavity. Other pins having flat ends locate the core in only one directional line. Still other pins having tapered ends require special pockets in the printout section of the core, which pockets have sides that must be formed adjacent to the tapered surfaces of these pins. The configurations of the space around the printout portions of the cores permit molten metal injected into the die to produce a skin or skull over the printout portions, which skin can have thicker ribs or portions through it for further reinforcing the printout portions. These printout portions on the parting line between two dies may have restrictions at the junction of the printout portion with the main portion of the core to form break-off rings. These rings and ribs may be formed either in the die or in the printout portion of the core, or both.
摘要翻译：定位销具有切口端，每个端部在压铸模具中同时限制一次性芯在两个正交方向上的移动。多个这些引脚单独和与其他引脚突出到压铸模具中的打印输出腔之间的空间和位于该空腔中的消耗性芯的打印输出部分。具有扁平端部的其他销将芯仅定位在一个方向线上。具有锥形端部的其他销钉在芯部的打印部分中需要特殊的凹坑，这些凹口具有必须邻近这些销的锥形表面形成的侧面。核心的打印输出部分周围的空间的配置允许注入到模具中的熔融金属在打印输出部分上产生皮肤或颅骨，该皮肤可以具有较厚的肋或通过其的部分，以进一步加强打印输出部分。在两个管芯之间的分型线上的这些打印输出部分可能在打印输出部分与芯部的主要部分的接合点处具有限制，以形成断开环。这些环和肋可以形成在模具中或在芯的打印输出部分中，或两者形成。
