Abstract
The propeller hub casting mold cavity structure of the utility model, including a pair of of the metal mold mutually fastened, there is sand core in metal mold, on the periphery of sand core, there are four the cylinders that can be cast as propeller blade mounting hole, shape forming cavity between sand core and metal mold, four cylinder two sides on sand core positioned at periphery are equipped with symmetrical graphite block, and the cylinder is made of the sand mold core segment among two graphite blocks and two graphite blocks.The propeller hub casting mold cavity structure of the utility model, when casting, due to that can be quickly cooled down at graphite block with the presence of graphite block, bubble is not generated, while reducing the casting amount of copper water, the amount of machining after reducing workpiece casting, it is time saving and energy saving, material is saved, production cost is reduced.
Description
Technical field
The utility model relates to a kind of propeller hub casting mold cavity structures.
Background technique
Propeller hub is the component for installing blade, and propeller hub is in rotational-like.As shown in Figure 3: there are four peaces on propeller hub 7 periphery
Fill the mounting hole 8 of blade.Propeller hub casting mold cavity structure includes a pair of of the metal mold mutually fastened, there is sand core in metal mold,
On the periphery of sand core there are four the cylinder that can be cast as propeller blade mounting hole 8, formation type between sand core and metal mold
Chamber.Often occur more bubble when casting at blade mounting hole, cause waste product, the reason is that cooling velocity is slow herein.For
It solves the above problems, some increases wall thickness herein in casting, can significantly reduce the generation of bubble, but increases copper
The dosage of water, is a kind of waste of resource, while increasing the processing capacity after workpiece casting, and the machining after casting is time-consuming to take
Power.
Summary of the invention
That the purpose of the utility model is to provide a kind of structures is simple, casting when do not generate bubble at blade mounting hole, mention
High finished product rate, the propeller hub casting mold cavity structure for reducing production cost, overcome the deficiencies in the prior art.
The propeller hub casting mold cavity structure of the utility model, including a pair of of the metal mold mutually fastened, in metal mold
Inside there is sand core, there are four the cylinder that can be cast as propeller blade mounting hole, sand core and metal molds on the periphery of sand core
Between shape forming cavity, four cylinder two sides on sand core positioned at periphery are equipped with symmetrical graphite block, the cylinder by
Sand mold core segment among two graphite blocks and two graphite blocks is constituted.
The propeller hub casting mold cavity structure of the utility model, when casting, due to the presence of graphite block, at graphite block
It can be quickly cooled down, not generate bubble, while reduce the casting amount of copper water, the amount of machining after reducing workpiece casting is time saving
It is laborsaving, material is saved, production cost is reduced.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of specific embodiment of the present invention；
Fig. 2 is A-A section amplification figure shown in FIG. 1；
Fig. 3 is the schematic cross-sectional view of propeller hub.
Specific embodiment
It is as shown in Figure 1, 2: the propeller hub casting mold cavity structure of the utility model, including a pair of of the metal mutually fastened
Type 1 has sand core 3 in metal mold 1, and on the periphery of sand core 3, there are four the cylinders that can be cast as propeller blade mounting hole 8
4, shape forming cavity 2 between sand core 3 and metal mold 1.Four 4 two sides of cylinder on sand core 3 positioned at periphery are equipped with symmetrically
Graphite block 6, cylinder 4 is made of 3 part of sand core among two graphite blocks 6 and two graphite blocks 6.When casting, due to having
Graphite block 6 exists, and can be quickly cooled down at graphite block 6, not generate bubble, the rejection rate of casting significantly reduces, reduces simultaneously
The casting amount of copper water, the amount of machining after reducing workpiece casting is time saving and energy saving, saves material, reduces production cost.
