Description
Technical Field
The invention relates to a wax injection machine mold device and a method.
Background
In long-term working practice, the rear end of an exhaust manifold of the traditional supercharged engine is directly connected with a straight-tube three-way catalytic device, so that the high-temperature resistance is poor, the whole layout of the engine is not facilitated, more troubles are brought to the layout of a chassis system, and the operation and the use of workers are not facilitated and the service life is shortened. For example, CN201620476627.9 is a new air cleaning device at the supercharging exhaust end of an automobile. The mandrel directly reflects the internal structure shape of the casting, and the quality of the mandrel directly influences the internal structure of the casting and the generation of casting defects. Although the existing core shaft adopts a shell core machine to manufacture the core, because the exhaust end cone inner cavity mechanism is relatively large, the shell core machine is used for manufacturing the core, the strength of the core shaft is influenced because the crust thickness is thin, or the crust thickness is thick and inconsistent, the gas generation amount of the core shaft is large, the casting gas hole defects are caused, and the sand amount is increased, so that the core shaft cost is increased. Because this kind of exhaust end awl inner chamber dabber is hypertrophied, traditional shell core machine system core technology, dabber crust thickness inequality leads to because of the thin dabber intensity of crust thickness is low, and the big casting defect that arouses of the thick dabber gas production of crust thickness and increases with the sand volume, consequently will solve the dabber in the dabber manufacturing process and produce the production problem that the dabber crust is inhomogeneous leads to the foundry goods defect, need solve the problem of the homogeneity of dabber crust thickness and intensity.
At present, a Chinese patent with a publication number of CN205033459U on the market discloses a wax injection machine, which comprises a machine frame, wherein a wax supplement oil cylinder is arranged on the right side of the machine frame; a working table top is arranged at the top of the rack, a wax injection oil cylinder is arranged at the rear end of the right side of the working table top, and a wax storage barrel is arranged at the left side of the wax injection oil cylinder; the front end of the right side of the working table is provided with a wax injection mechanism, and a wax injection oil cylinder is in driving connection with the wax injection mechanism; an electric cabinet is arranged above the wax injection mechanism; the front end of the left side of the working table surface is provided with a mold and a fixed template, and the fixed template is positioned above the mold; a template working oil cylinder is fixedly arranged on the upper end surface of the fixed template, a working template is arranged below the fixed template, the working template is X-shaped, and the working oil cylinder is in driving connection with the working template; the working template is positioned above the die.
Although the wax injection machine enlarges the working visual field, is convenient to operate and safer, before the wax injection machine performs injection operation each time, a worker needs to bend down to place the mold below the fixed template, and after the injection operation of the wax injection machine is completed, the worker needs to bend down to take out the mold from the lower part of the fixed template, and the repeated operation easily causes safety accidents. The investment casting is also called lost wax casting, and comprises the procedures of wax pressing, wax trimming, tree forming, slurry dipping, wax melting, molten metal casting, post-treatment and the like. Lost wax casting is a process in which a wax pattern for a part to be cast is made of wax, and then the wax pattern is coated with slurry, that is, a clay pattern. And drying the mud mold, and roasting to form the ceramic mold. Once baked, the wax pattern is completely melted and lost, and only the ceramic pattern is left. Generally, a pouring gate is left when a mud mould is manufactured, then molten metal is poured into the mud mould from the pouring gate, and after the mud mould is cooled, required parts are manufactured. Therefore, the manufacture of the wax mould is an important process and is completed by adopting a wax injection machine, the molding of the wax mould is greatly influenced by the wax injection machine, at present, most of the wax injection machines have insufficient stability, and therefore, the manufactured wax mould has defects frequently.
