Abstract
The utility model discloses a kind of casting dies of automobile engine aluminum alloy cylinder cover, it is related to engine cylinder cover casting mould technical field, including casting die ontology, is equipped with running channel in casting die ontology, spark plug thermal center point is equipped in casting mold ontology, casting mold ontology is equipped with riser.The utility model structure is simple, easy to use, is suitble to promote the use of；The quality of cast article is high, and product rejection rate is low.
Description
Technical field
The utility model relates to engine cylinder cover casting mould technical fields, close more particularly to a kind of automobile engine aluminium
The casting die of golden cylinder cap.
Background technique
The cylinder cap of automobile engine is mounted on above cylinder body, from top seal cylinder and constitutes combustion chamber.It often with height
Warm high-pressure gas is in contact, therefore bears very big thermic load and mechanical load.Cylinder head is cast using aluminum alloy materials, and aluminium closes
The thermal conductivity of gold is good, is conducive to improve compression ratio.Aluminum alloy cylinder cover is using parallel four die sinkings casting machine metal gravity casting
It makes, unilateral bottom surface pouring technology, interiors of products shape is formed by sand core, and structure is complicated.Currently, the spark plug position in cylinder cap casting
It sets there are serious thermal center, shrinkage porosite occurs in spark-plug location after causing casting to form, poor product quality, and rejection rate is higher.
Utility model content
The purpose of this utility model is that solve the above-mentioned problems and provides a kind of automobile engine aluminum alloy cylinder cover
Casting die.
The utility model achieves the above object through the following technical schemes:
A kind of casting die of automobile engine aluminum alloy cylinder cover, including casting die ontology, the casting die ontology
It is interior to be equipped with running channel, spark plug thermal center point is equipped in casting mold ontology, casting mold ontology is equipped with riser.
Preferably, the spark plug thermal center point equidistantly distributed.
Preferably, the riser is located at the surface of spark plug thermal center point.
Preferably, the quantity of the spark plug thermal center point is 3~5.
Preferably, the riser approximation is in truncated conical shape.
The utility model has the beneficial effects that: the utility model structure is simple, and it is easy to use, it is suitble to promote the use of；Casting
The quality for making product is high, and product rejection rate is low.
Detailed description of the invention
Fig. 1 is the top view of the utility model；
Fig. 2 is the Section A-A figure of the utility model.
Wherein: 1, casting die ontology；2, riser；3, spark plug thermal center point；4, running channel.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
As depicted in figs. 1 and 2, the utility model includes casting die ontology 1, is equipped with running channel 4 in casting die ontology 1.
Spark plug thermal center point 3 is equipped in casting mold ontology 1.Casting mold ontology 1 is equipped with riser 2.Spark plug thermal center point 3 is equidistant
Distribution.The quantity of spark plug thermal center point 3 is 3~5, in the present embodiment, and the quantity of spark plug thermal center point 3 is 4.2, riser
In the surface of spark plug thermal center point 3.Approximate riser 2 is in truncated conical shape.When work, molten aluminum is entered in running channel 4, in casting solidification
It carries out lasting molten aluminum to 3 position of spark plug thermal center point during molding to supplement, spark plug thermal center point 3 directly connects with riser 2
It connects and sets up Feeding channel, continue feeding in 3 position forming process of spark plug thermal center point, solve the problems, such as shrinkage porosite, reduce cylinder cap
Rejection rate.
The above is only the preferred embodiments of the utility model, and therefore it does not limit the scope of the patent of the utility model.Ability
The those of ordinary skill in domain is appreciated that in the case where not departing from the principles of the present invention and objective can be to these implementations
Mode carries out a variety of variations, modification, replacement and deformation.The scope of the utility model is defined by the claims and their equivalents.
