Description
Technical field
The utility model relates to a kind of manufacturing equipment of internal combustion engine part, especially relates to a kind of combination sand mold for valve rocker bearing.
Background technology
Internal combustion engine belongs to a kind of dynamic power machine of burning fossil fuel, from prior art, internal combustion engine can be divided into gasoline engine and diesel engine, gasoline engine and the common feature of diesel engine need fuel oil injected gas in-cylinder combustion, gas expansion thus produce thrust and promote the motion of cylinder piston, this straight reciprocating motion is converted to rotary motion and exports by piston again, in fuel oil in the cylinder combustion process, need the fuel oil straying quatity in control cylinder, the injection rate of air and the discharge rate of waste gas, the control of above-mentioned amount needs to be achieved effective control of cylinder gate.And internal combustion engine rocking arm belongs to the major way controlling valve, and internal combustion engine rocking arm is mainly divided into intake rocker and exhaust rocker arm, because above-mentioned rocking arm needs long motion in internal combustion engine operation, above-mentioned athletic meeting causes the wearing and tearing of mechanical device, for suppressing above-mentioned wearing and tearing, need to add effective lubricating arrangement in these moving components.Therefore rocker arm support needs special sand mold to cast in the fabrication process, otherwise easily causes air entrapment too much, affects the quality of bearing.
Utility model content
The purpose of this utility model is to provide a kind of combination sand mold for valve rocker bearing, and efficiently solve the casting problem of rocker arm support, the technical scheme of employing is as follows:
A kind of combination sand mold for valve rocker bearing, comprise low mold frame and upper framed, several pillar is provided with bottom described low mold frame, column upper section is mold cavity, both sides, mold cavity top are exhaust support mould chamber, it is air inlet support mould chamber in the middle part of mold cavity, both sides, described framed top are corresponding with vented mould chamber to be provided with two and to pour into bolt, described perfusion bolt by screw tightening upper framed on, in the middle of described perfusion bolt, there is through hole, described through hole and exhaust support mould chamber are by charging hole UNICOM, described framed upper inner and air inlet support mould chamber correspondence position are provided with a through hole groove, described groove is by first row pore and air inlet support mould chamber UNICOM, described framed sidewall also has second row pore and mold cavity UNICOM.
Further, described second row pore comprises upper air-vent and lower steam vent.
Further, described pillar top is circular arc pinnacle.
Further, described framed be hierarchic structure with the junction of low mold frame.
After adopting this structure, effectively can solve the casting problem of rocker arm support, finished product is homogeneous, and intensity is high, and bubble is few.
Accompanying drawing explanation
Fig. 1 is a kind of schematic diagram of the combination sand mold for valve rocker bearing.
Detailed description of the invention
A kind of combination sand mold for valve rocker bearing as shown in Figure 1, comprise low mold frame 1 and upper framed 2, above framed 2 is hierarchic structure 13 with the junction of low mold frame 1, several pillar 3 is provided with bottom described low mold frame 1, pillar 3 top is circular arc pinnacle, pillar 3 top is mold cavity 4, both sides, mold cavity 4 top are exhaust support mould chamber 6, it is air inlet support mould chamber 7 in the middle part of mold cavity 4, described framed 2 both sides, top are corresponding with vented mould chamber 6 to be provided with two and to pour into bolt 8, described perfusion bolt 8 is tightened on upper framed 2 by screw 14, in the middle of described perfusion bolt 8, there is through hole, described through hole and exhaust support mould chamber 6 are by charging hole 5 UNICOM, described framed 2 upper inner and air inlet support mould chamber 7 correspondence position are provided with a through hole groove 10, described groove 10 is by first row pore 9 and air inlet support mould chamber 7 UNICOM, the described sidewall of framed 2 also has second row pore and mold cavity 4 UNICOM, second row pore comprises upper air-vent 11 and lower steam vent 12.
The above, be only detailed description of the invention of the present utility model, and those of ordinary skill in the art are in the scope that the utility model discloses, and the change that can expect easily, within the protection domain that all should be encompassed in utility model.
