Description
Technical field
The utility model relates to a kind of manufacturing equipment of internal combustion engine part, especially relates to a kind of precoated sand mould manufacturing valve rocker.
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 rocking arm needs special sand mold to cast in the fabrication process, otherwise easily causes air entrapment too much, affects intensity and the quality of rocking arm.
Utility model content
The purpose of this utility model is to provide a kind of precoated sand mould manufacturing valve rocker, and efficiently solve the casting problem of rocking arm, the technical scheme of employing is as follows:
A kind of precoated sand mould manufacturing valve rocker, comprise precoated sand housing, described precoated sand housing two side is respectively provided with a gantry support, described gantry support is fixed a hydraulic piston, the piston axle of described hydraulic piston is fixedly connected with top board through the sidewall of precoated sand housing, described precoated sand housing upper center is provided with a tapping hole, tapping hole both sides are respectively equipped with a valve rocker casting die cavity, described valve rocker casting die cavity is provided with several steam vent, has several flow-guiding channel between described two valve rockers casting die cavity.
Further, described precoated sand housing both sides are also provided with and pick up the ears.
Further, the quantity of described each valve rocker casting die cavity steam vent is three, is respectively equipped with position before, during and after valve rocker casting die cavity.
Further, described flow-guiding channel is the groove with corrugated projection.
After adopting this structure, effectively can solve the casting problem of valve rocker, finished product is homogeneous, and intensity is high, and bubble is few.
Accompanying drawing explanation
Fig. 1 is a kind of schematic diagram manufacturing the precoated sand mould of valve rocker.
Detailed description of the invention
A kind of precoated sand mould manufacturing valve rocker as shown in Figure 1, comprise be provided with pick up the ears 12 precoated sand housing, described precoated sand housing two side is respectively provided with a gantry support 2, 3, described gantry support 2, a hydraulic piston 4 is fixed on 3, 5, described hydraulic piston 4, the piston axle 8 of 5 passes sidewall and the top board 6 of precoated sand housing, 7 are fixedly connected with, described precoated sand housing upper center is provided with a tapping hole 9, tapping hole 9 both sides are respectively equipped with a valve rocker casting die cavity 10, described valve rocker casting die cavity 10 is provided with several steam vent 11, in general the quantity of each valve rocker casting die cavity 10 steam vent 11 is three, before being respectively equipped with valve rocker casting die cavity 10, in, rear position, several flow-guiding channel 13 is had between described two valve rockers casting die cavity 10, flow-guiding channel 13 is the groove with corrugated projection, be conducive to the processing that semi-finished product are follow-up.
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.
Claims (4)
