| A method of casting valve seat inserts comprises pouring molten metal into a gating system of a mold plate stack wherein mold plates are located between top and bottom molds wherein the gating system includes a casting header, down-sprue, horizontal sprue, up-sprues, runners, and gates in fluid communication with mold cavities configured to form the valve seat inserts. The method includes filling the mold cavities with the molten metal, and controlling solidification of the molten metal in the mold cavities by means of an outer thermal barrier which retards heat transfer in mold plate material between the mold cavities and an outer periphery of the mold plate stack. An inner thermal barrier can be sued to further control solidification of the molten metal. Valve seat inserts produced using the thermal jacket molds can exhibit an improved microhardness distribution which provides improved machining and higher yield. | ||||||

| This invention relates to the production casting of molten metal. In such casting, the molten metal being poured into one cavity may be splashed or overflowed into another adjacent cavity. The invention provides a splash guard which defines a barrier to the molten metal and prevents such inadvertent introduction of the molten metal into an adjacent cavity. The splash guard preferably comprises a substantially solid object made of a material, such as graphite, that retains its structural integrity at high temperatures and upon contact with molten metal, but which does not strongly adhere or bond to the molten metal upon cooling. The invention can be embodied in both manual and automatic casting lines. In a manual casting line, the splash guard may physically contact a surface of the mold to create the molten metal barrier between the cavities. In an automated casting line, the splash guard may be raised above the mold surface, and form the molten metal barrier through use of the surface tension of the molten metal, so as to avoid interference with the weighing scales on the automated pouring device. | ||||||

| A method for moulding multiple castings in which each mould is fed from a source of molten metal through a thin slit the width of which lies in the range 1.25 mm down to 0.25 mm. The cast articles can easily be removed from the runner and riser system after casting without a machining operation so that the casting moulds can be packed closer together and more castings can be produced from each mould assembly. The thin slit also acts as a filter. A particular mould assembly seen in FIG. 2 is cylindrical and comprises a plurality of wedge-shaped mould segments 2 having mould cavities 4 in abutting faces. A central runner passage 6 is formed when the mould segments are assembled and the metal flows into the mould cavities through narrow slits 10 in one edge of each mould. After casting and removal of the mould the narrow flashing formed in the slits can easily be broken to remove the cast articles from the metal formed in the central runner passage. | ||||||

| The invention relates to a mould assembly including a plurality of individual moulds. The mould assembly of the present invention is made by separately transfer moulding a starter base 16, a plurality of moulds 12, a downpole 14 and pouring cup 19, providing each with mechanical locking features, such as screw threads, and joining them together into the assembly. Much greater flexibility is thereby achieved in materials and wall thicknesses, which can be different in different parts of the assembly to suit strength and heat transfer requirements, individual bits can be replaced, and the transfer moulding produces a compact homogeneous ceramic structure. | ||||||

| In a process for making refractory articles, such as cores and moulds for use in casting metals, the articles are formed from dies using a refractory material mixed with a thermosetting resin. The articles are formed with the mixture heated to a softened state and the resin is cured. Thereafter the article has to be fired and problems have arisen with deformation of the articles during the firing process.With the present invention, the articles, 8, which as can be seen in FIG. 2 are mould segments, are bound into an assembly with a flexible refractory tape (15) which shrinks on firing to a greater extent than the articles, and thus pulls the assembly tightly together whereby each article provides support for the adjacent article and prevents distortion. The joint faces between the mould segments are thus held in tight abutment and for pouring metal into the mould, the firing cup is fitted and a coating of refractory slurry is brushed on without removing the tape to seal the assembly.The process is also applicable to the manufacture of cores to prevent bending during firing. | ||||||

| An improved method is utilized to make an improved mold for forming a plurality of small objects, such as piston rings. The mold is made by stacking a plurality of mold sections formed of gas permeable material, such as CO.sub.2 sand, resin bonded sand or green sand. The stacked mold sections are then clamped together to hold them against movement relative to each other. A wet coating of liquid ceramic material is then applied over the stack of mold sections. This liquid ceramic mold material is dried to form a rigid gas permeable ceramic casing which encloses the stack of mold sections. The rigid casing of ceramic material holds the mold sections against movement relative to each other to prevent break-out of metal from between the mold sections when a flow of molten metal is directed into the mold cavities. Due to the gas permeable construction of both the rigid ceramic casing and the mold sections, gas can readily escape from the mold as the molten metal enters the mold cavities. | ||||||
| 156 | Process for manufacture of valve seat | US971697 | 1978-12-21 | US4241492A | 1980-12-30 | Arthur S. Hedberg |
| The present invention concerns a method of manufacture of valve seats which comprises forming a series of vertically stacked molds each having at least one mold cavity with a configuration approximating that of a ring-shaped valve seat insert blank. After the molds are formed, they are stacked and the cavities are connected by a common molten metal passageway in such a way that the passageway connects with an axially facing outer surface of each mold cavity to provide a lap gating relationship. Molten metal is then poured into the lap gated passageway to form a series of valve seat insert blanks each having a gate formed on an axially outer face. The blanks are then removed from the molds. Various grinding operations are then applied to the blanks and the axially outer-facing surfaces of the blanks are ground to remove the gates to form valve seats for use in internal combustion engines. | ||||||

| Molten metal is forced upwardly by bottom pressure casting through an ingate and into the casting cavity of a mold having a dam to retain the metal in the cavity after the ingate has been drained. The mold is preferably formed from separable graphite cope and drag sections and may include an outer cast iron chill ring to impart the desired outer contour to the casting with accuracy. A plurality of such molds may be stacked and filled in one pouring operation.
