Abstract
The invention discloses a water injection channel core with a core bar for a cylinder cover. The strength and rigidity of the sand core are effectively improved by implanting the specially-shaped core bar in the water injection channel sand core so as to prevent the water injection channel core from floating upwards and breaking during molten iron casting, so that overall dip-coating is realized on the YC6B series cylinder cover in the end. The special shape of the core bar is designed by combining the structure and shape of the water injection channel core and the characteristics of mold core shooting. The water injection channel core can meet technological requirements and ensure the quality of sand core shooting. As only the core bar needs to be put in a mold before core shooting, the operation is simple; material obtaining is also relatively simple; common steel and iron materials are subjected to punch forming according to shapes in drawings; and the requirements on surface quality and size accuracy are low. The water injection channel core has a relatively good effect and relatively good strength and rigidity, the upward floating phenomenon of the water injection channel core is avoided, the overall dip-coating is realized on the used cylinder cover in the end, and the cavity quality of a cylinder cover casting is greatly improved.
Description
Technical field
the present invention relates to a kind of cylinder cap jetting road core with arbor that can prevent cylinder cap jetting road core floating.
Background technology
at present, YC6B series cylinder cap wants the floating of jetting road core to have to adopt non-integral dipping process owing to taking into account, it is core assembly just after the independent dip-coating of each core, baking, when core assembly, with " 7 " font arbor, jetting road core is fixed on the core of chassis, jetting road core floating, disconnected core while preventing from pouring into a mould, this technological operation operation is many and loaded down with trivial details, and core cavity is second-rate.
Summary of the invention
the object of the present invention is to provide a kind of in order to prevent jetting road core floating, to implant a novel arbor that can prevent cylinder cap jetting road core floating at jetting road in-core, can effectively prevent jetting road core floating, the arbor of disconnected core, can make a series of cylinder caps realize entirety, soak floating simple in structure, easy to manufacture, easy to use.Shape is special, can effectively prevent the arbor of jetting road core floating, disconnected core, after using, can make a series of cylinder caps finally realize overall dipping process.
Technical solution of the present invention is such, a kind of cylinder cap jetting road core with arbor, comprise arbor, mold core chamber, end handle, figure, leading portion, it is characterized in that arbor (1) is arranged on mold core chamber (2), bending between arbor (1) figure (4) and leading portion (5), under arbor (1), be that the end of bending is (3).
leading portion (5) is taper.
? the end is right angle (3) with figure (4) bending.
Arbor (1) is metalwork.
Arbor (1) is nonmetal parts.
Arbor (1) is U font.
? arbor (1) is bonded at mold core chamber (2) with resin.
Arbor (1) is consolidated in mold core chamber (2) by alignment pin.
Handle (3) end external port is in sideline, top, mold core chamber (2) at the end.
Figure (4) is cylindricality.
the beneficial effect of the present invention compared with original production technology is:
1, can effectively prevent the core cast of jetting road time, floating causes wall thin.
2, reduce the disconnected core percent defective of jetting road core, drop to 0.0037% by former 0.04%, the range of decrease is waterborne up to 90%.
3, make YC6B series cylinder cap realize overall dipping process, not only reduced some many and loaded down with trivial details operational sequences, and improved the inner chamber quality of foundry goods;
4, to not carrying out any change on original production equipment, moulds of industrial equipment, sand core structure, easy to operate, before mould core shooting, put into arbor, normal use after core penetrates, in cleaning process, arbor is taken out to recovery, on ecological environment also without any pollution and impact.
Accompanying drawing explanation
it is such that structure of the present invention forms:
fig. 1 is the installation assembling front view of a kind of cylinder cap jetting road core with arbor of the present invention.
fig. 2 is that schematic diagram is looked on the installation assembling right side of a kind of cylinder cap jetting road core with arbor of the present invention.
fig. 3 is the installation assembling schematic top plan view of a kind of cylinder cap jetting road core with arbor of the present invention.
fig. 4 is that the master of the arbor of a kind of cylinder cap jetting road core with arbor of the present invention looks schematic diagram.
fig. 5 is that schematic diagram is looked on the arbor right side of a kind of cylinder cap jetting road core with arbor of the present invention.
in Fig. 1～Fig. 5, arbor (1), mold core chamber (2), the end, are (3), figure (4), leading portion (5).
The specific embodiment
below in conjunction with accompanying drawing, the present invention is further described.
Embodiment 1, arbor (1) overall length 36mm, height overall 32mm, thickness 1.6mm, the end, is (3) 15mm, figure (4) 6mm, leading portion (5) 12mm, figure (4) is to the turning transition arc R1～R10 of leading portion (5).
accompanying drawing 1 is jetting road arbor processing drawing, the angle of upper end rotation is arbor (1) jack-up to be strengthened to arbor (1) end the mold thickness of (3) for place arbor (1) in mould time, after preventing core shooting, arbor (1) exposes core surface, arbor when cast (1) outer surface directly contact with molten iron and is bonded together more difficult taking-up, and the right angle, workload lower end that increases cleaning process is that easy cleaning operation taking-up outside foundry goods is exposed in the one end in order to guarantee to pour into a mould rear arbor (1).
accompanying drawing 2 is jetting road core schematic diagrames of putting into arbor (1).
very simple of operating procedure, only need in mold core chamber (2), to place arbor (1) before core shooting direct core assembly after all core core shootings, whole core group entirety dip-coating after core assembly baking, operate very simple and conveniently, reduced a lot of loaded down with trivial details operations.
embodiment 2, a kind of cylinder cap jetting road core with arbor, comprise arbor, mold core chamber, end handle, figure, leading portion, it is characterized in that arbor (1) is arranged on mold core chamber (2), bending between arbor (1) figure (4) and leading portion (5), under arbor (1), be that the end of bending is (3).Leading portion (5) is taper.The end is right angle (3) with figure (4) bending.Arbor (1) is metalwork, and arbor (1) is nonmetal parts, and arbor (1) is U font.Arbor (1) is bonded at mold core chamber (2) with resin.Arbor (1) is consolidated in mold core chamber (2) by alignment pin.Handle (3) end external port is in sideline, top, mold core chamber (2) at the end.Figure (4) is cylindricality.
