Abstract
The utility model relates to an automotive engine aluminum alloy intake manifold blank, in particular to an automotive engine intake manifold throttle valve device which overcomes the defect of loose of an intake manifold blank throttle valve. The automotive engine intake manifold throttle valve device is characterized in that a throttle valve end face cavity is connected on a throttle valve cavity, a blind riser cavity is connected on the throttle valve end face cavity, a cast iron movable block is arranged on the side face of the throttle valve cavity, and a thermal couple and a heating nozzle are arranged above the blind riser cavity; the cast iron movable block is located to be fixedly connected with a die body. The throttle valve end face cavity is connected on the throttle valve cavity, and the blind riser cavity is connected on the throttle valve end face cavity. The automotive engine intake manifold throttle valve device has the technical advantages of being simple in structure, low in cost, and easy to realize, the product percent of pass reaches 99%, a blind riser and the heating nozzle are arranged at a concave position of a throttle valve, so that the thick and large portion of the throttle valve cavity is quickly cooled, the effect of progressive solidification is achieved, the defect of internal loose of the throttle valve is overcome, and the product percent of pass is improved.
Description
Technical field
The utility model relates to automobile engine aluminum alloy air inlet manifold blank, is specially a kind of air intake manifold of automotive engine throttle valve device that solves intake manifold blank air throttle rarefaction defect.
Background technology
Aluminum alloy air inlet manifold is the important component part of part of automobile engine, all more complicated of inlet manifold general structure, and bending amplitude is large, affected by the conditions such as engine performance, installing space, depanning direction, and air throttle position is thick large.When cast, easily produce the defects such as air pit is loose at air throttle end face, casting qualification rate less than 50%, defect can only be saved by welding manner, wastes time and energy; Air throttle position outward appearance does not have defective blank in the time of processing end face, to have 20% left and right rarefaction defect yet.If foundry goods air throttle position defectiveness, can have a strong impact on the power of engine, the use of at all can not installing, can only scrap, and brings huge economic loss to enterprise.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, with low cost, operate, overhaul convenient, flexible air intake manifold of automotive engine throttle valve device.The purpose of this utility model is achieved in that it comprises mold, cast iron loose piece, location, air throttle end face cavity, thermocouple, heating nozzles, blind riser cavity, air throttle cavity, it is characterized in that: in described mold, be provided with cast iron loose piece, air throttle end face cavity, blind riser cavity, air throttle cavity, described air throttle cavity top is connected with air throttle end face cavity, air throttle end face cavity top is connected with blind riser cavity, described air throttle cavity side is provided with cast iron loose piece, described blind riser cavity top is provided with thermocouple, heating nozzles, cast iron loose piece is connected with mold through locating to fix.Described air throttle cavity top is connected with air throttle end face cavity, air throttle end face cavity top is connected with blind riser cavity, air throttle end face cavity, blind riser cavity, air throttle cavity are cavity body structure, and air throttle end face cavity is the one cavity communicating with blind riser cavity, air throttle cavity.Technique effect of the present utility model is simple in structure, with low cost, easily realizes, and product percent of pass reaches 99%.By increase blind riser and heating nozzles at air throttle fault location, make the thick large part of air throttle cavity cooling rapidly, realize the effect of consecutive solidification, solve air throttle internal defect defect, improve product percent of pass.
accompanying drawing explanation
Fig. 1 is the utility model structural principle schematic diagram; Fig. 2 is the utility model structural principle schematic top plan view.
the specific embodiment
It comprises mold 1, cast iron loose piece 2, location 3, air throttle end face cavity 4, thermocouple 5, heating nozzles 6, blind riser cavity 7, air throttle cavity 8.It is characterized in that: in described mold 1, be provided with cast iron loose piece 2, air throttle end face cavity 4, blind riser cavity 7, air throttle cavity 8, wherein air throttle cavity 8 tops are connected with air throttle end face cavity 4, air throttle end face cavity 4 tops are connected with blind riser cavity 7, they are cavity structure, are the entirety communicating.Described air throttle cavity 8 sides are provided with cast iron loose piece 2, and described blind riser cavity 7 tops are provided with thermocouple 5, heating nozzles 6.Below in conjunction with accompanying drawing in detail the utility model operation principle, the course of work are described in detail.Cast iron loose piece 2 is fixed in mold 1 by locating 3, and cast iron loose piece 2 can be realized the effect of accelerating cooling air throttle cavity 8.Heating nozzles 6 and thermocouple 5 are two independently parts, are fixed on mold 1 by jump ring.Adopt the lasting heating method of heating nozzles 6 to blind riser cavity 7, then by the monitoring temperature of thermocouple 5, can make blind riser cavity 7 finally cooling.Realized the be connected object of overall consecutive solidification of air throttle cavity 8, air throttle end face cavity 4, blind riser cavity 7, air throttle defect has obtained effective solution.The utility model course of work: when work, cast iron loose piece 2 is connected in mold 1 and location 3 grooves that match by locating 3, heating nozzles 6 are by after natural gas igniting, blind riser cavity 7 being continued to heat, and thermocouple 5 is monitored blind riser cavity 7 temperature.Aluminium alloy is full of successively air throttle cavity 8, air throttle end face cavity 4, is finally full of blind riser cavity 7, has formed foundry goods air throttle face shaping, thereby has overcome air throttle defect, and obtained qualified inlet manifold foundry goods.
