摘要： A cylinder block has a cylinder block body and a cylinder liner block mounted by casting in the cylinder block body. The cylinder liner block is formed from a material having a rigidity larger than that of the cylinder block body, and the cylinder liner block comprises a liner section mounted by casting in position in a cylinder barrel portion of the cylinder block body, and a reinforcing wall section mounting by casting in position in a bearing wall of a crank case portion of the cylinder block body in a. Thus, it is possible to increase the wear resistance of cylinders in the cylinder block, as well as to provide an increase in performance by reductions in vibration and noise of the engine including the cylinder block, and to provide reductions in size, weight and cost of the cylinder block by a reduction in thickness of the bearing walls.

摘要： A method of making a cast dual-metal monoblock, by (i) casting an iron-based insert to define walls for one or more chambers or passages for each of combustion, piston reciprocation, gaseous induction and gaseous exhaust; (ii) forming a sand core wrapping directly about said insert to cover such insert except for the extremities of the walls defining the passages for gaseous induction and exhaust and the chamber for piston reciprocation, such extremities being remote from the walls defining the combustion chamber; and (iii) die casting an aluminum-based metal jacket about the assembly of said insert and core wrapping to complete the dual-metal monoblock. Advantageously, in step (ii), there is further included the formation of a top sand core assembly for defining one or more oil and/or valve train passages or chambers, the top sand core assembly being stationed to rest on the insert during casting of the jacket.

摘要： A method for producing a cylinder head having a tubular exhaust port liner made of a ceramic material is disclosed. The method comprises providing a covering layer of refractory fibers around the outer circumference of the exhaust port liner, applying a metal cap over each end of the covered exhaust port liner and setting the covered exhaust port liner into a mold. A cylinder head then is cast around the exhaust port liner so that the portions of the metal caps contacting the cylinder head are fused to the cylinder head. The metal caps are bored out to open up the exhaust port after predetermined treatments are performed on the cylinder head.

摘要： This invention relates to an improved method of manufacturing a heater nozzle for an injection molding system. The heater nozzle has a helical heating element which is cast into an outer portion around an inner liner through which the melt flows. The outer portion is formed of a conductive material such as a beryllium copper alloy and the inner liner is formed of a durable corrosion resistant material such as stainless steel to provide an excellent combination of these characteristics. The heater nozzle is made by positioning the heating element around a pre-heated solid threaded liner in a mold and pressure casting the beryllium copper outer portion around them. The elongated liner is very accurately located in the mold by having the lower end received in a seat in the mold and the upper end received in an aperture through the plunger as it closes. In another embodiment, the inner liner is provided with a Y-shaped joint by attaching an arm portion to it by brazing them in a vacuum furnace prior to the pressure casting step. After pressure casting, the liner is then drilled to form the melt passage through it and the heater nozzle is machined to remove the projecting ends of the liner and to finish the outside according to predetermined dimensions. This provides a very economical method of making heater nozzles with the necessary combination of characteristics to withstand the operating conditions of a large range of applications.
摘要翻译：本发明涉及一种制造注射成型系统加热器喷嘴的改进方法。加热器喷嘴具有螺旋加热元件，该螺旋加热元件被浇铸成围绕熔融物流过的内衬层的外部部分。外部由诸如铍铜合金的导电材料形成，内衬由耐腐蚀材料如不锈钢形成，以提供这些特性的优异组合。加热器喷嘴通过将加热元件围绕预成型的实心螺纹衬套定位在模具中并将其周围的铍铜外部部分压力铸造而制成。细长的衬垫通过使下端容纳在模具中的座中而非常精确地位于模具中，并且上端在其闭合时通过柱塞容纳在孔中。在另一个实施例中，通过在压力铸造步骤之前将它们固定在真空炉中，通过将臂部分附接到其上而将内衬设置有Y形接头。在压力铸造之后，然后钻出衬里以形成通过其的熔体通道，并且加热器喷嘴被加工以去除衬套的突出端并根据预定尺寸来完成外部。这提供了一种非常经济的制造加热器喷嘴的方法，其具有必要的特性组合以经受大范围应用的操作条件。

摘要： A method of producing a casting of a basis metal having a transplanted facing of a very hard material. Hard facing materials such as refractory metals and cemented carbides are sprayed by a metalizing gun in a layer onto a core piece, an intermediate layer of metal is then sprayed onto the first layer to protect the brittle hard facing material from the thermal shock of casting temperatures, the core piece positioned in a mold as at least a portion of the cavity wall thereof, an a casting formed against and interlocking with the intermediate layer. The casting and core piece are removed from the mold and the core piece detached from the casting, leaving the first layer as an integral part of the casting having a hard surface.

摘要： Disclosed herein is a method of constructing an engine having a cast iron cylinder liner and in which the engine block is die cast around the cylinder liner. The cylinder liner is cast with blind ports or recesses on the exterior surfaces. The outside and inside of the liner are machined to make the surfaces concentric, and the engine block is die cast around the liner by using a twopiece die with fingers which extend into the blind ports to prevent entry of the metal therein. The recesses are opened after the block is die cast by further machining of the inside surface of the liner.
