Abstract
The utility model provides an exhaust device of a mandrel of cylinder cover gate core sand, and relates to a cast technology. Bulged lower mold cores (3) are provided with exhaust holes (6) which are communicated with holes of a lower mold plate (1); a lower exhaust hole is formed in the position, between every two bulged lower mold cores (3), of the lower mold plate (1); exhaust plugs (5) are plugged in the lower exhaust holes; exhaust clearances (7) are formed in the lower mold plate (1) between the bulged lower mold cores (3) and a lower mold frame (2); and an exhaust groove (8) is formed in a right frame of the lower mold frame (2). By virtue of addition of exhaust holes, the exhaust clearances, the exhaust plugs and the exhaust groove, and the airflow is smooth, so that the exhaust device is more suitable for environment-friendly water-soluble casting sand, and has the characteristics of increase of production efficiency, high yield, facilitation of environmental protection and the like.
Description
Technical field
The utility model relates to foundry engieering, especially a kind of exhaust apparatus of cylinder cap gate core core mould.
Background technology
What cylinder cap generally adopted is the outer mold forming of wet type external mold or resin type, owing to existing after the unstability and graphitization expansion of molten steel solidification, because external mold modification easily causes micro-shrinkage porosite, causes combustion chamber fatigue strength to reduce, the defects such as dribbling of injection nozzle; While adopting resin sand to produce core, can produce penetrating odor, and inadaptable to the environmental requirement of current proposition, the made molding sand of environment-protective water dissolubility liquid adhesive is now proposed, and the water-soluble molding sand of this feature of environmental protection, exist and be difficult for loose poor fluidity, at the existing sand mo(u)ld plate casting that covers, yield rate is low.
Summary of the invention
The purpose of this utility model is to provide and no longer produces penetrating odor, the core of energy meet the requirement of environmental protection completely, and can solve because of external mold poor rigidity, and cause product material loose, cause performance to reduce, adopt swage, in order to adapt to use environment-protective water dissolubility molding sand, increase the exhaust apparatus of the cylinder cap gate core core mould of exhaust apparatus.
The purpose of this utility model adopts technical scheme, comprise and on lower bolster, be placed with low mold frame, connect with bolt between the two, in aforesaid low mold frame, on lower bolster, be connected with protruding lower mold core with connecting pin, its protruding lower mold core has steam vent, and steam vent communicates with counterdie plate hole, on lower bolster between two protruding lower mold core, there is lower steam vent, aforesaid lower steam vent is plugged with venting plug, has exhaust slot on the lower bolster between protruding lower mold core and low mold frame, on low mold frame left frame, has air discharge duct.
Further, above-mentioned protruding lower mold core has 6.
Further, on venting plug, have thin narrow slit.
The utility model, increases steam vent, exhaust slot, venting plug, air discharge duct, makes air-flow smoothness, and more applicable environment-protective water dissolubility molding sand, enhances productivity, and yield rate is high, is conducive to the features such as environmental protection.
Accompanying drawing explanation
Further illustrate the utility model below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation.
In figure: 1-lower bolster 2-low mold frame 3-projection lower mold core 4-connecting pin 5-steam vent 6-steam vent 7-exhaust slot 8-air discharge duct.
The specific embodiment
See Fig. 1, comprise and on lower bolster 1, be placed with low mold frame 2, connect with bolt between the two, on the interior lower bolster 1 of aforesaid low mold frame 2, be connected with protruding lower mold core 3 with connecting pin 4, its protruding lower mold core 3 has steam vent 6, and steam vent 6 communicates with lower bolster 1 hole, on lower bolster 1 between two protruding lower mold core 3, there is lower steam vent, aforesaid lower steam vent is plugged with venting plug 5, on the lower bolster 1 between protruding lower mold core 3 and low mold frame 2, has exhaust slot 7, on low mold frame 2 left frames, has air discharge duct 8.
Further, above-mentioned protruding lower mold core 3 has 6.
Further, on venting plug 5, have thin narrow slit.
Claims (3)
1. the exhaust apparatus of a cylinder cap gate core core mould, comprise and on lower bolster (1), be placed with low mold frame (2), connect with bolt between the two, the interior lower bolster of aforesaid low mold frame (2) (1) is above connected with protruding lower mold core (3) with connecting pin (4), it is characterized in that protruding lower mold core (3) has steam vent (6), steam vent (6) communicates with lower bolster (1) hole, on lower bolster (1) between two protruding lower mold core (3), there is lower steam vent, aforesaid lower steam vent is plugged with venting plug (5), on lower bolster (1) between projection lower mold core (3) and low mold frame (2), there is exhaust slot (7), on low mold frame (2) left frame, have air discharge duct (8).
2. the exhaust apparatus of a kind of cylinder cap gate core core mould according to claim 1, is characterized in that above-mentioned protruding lower mold core (3) has 6.
