Abstract
It the utility model is related to casting technology field, and in particular to a kind of sand core structure for the casting of sand wedge angle position.Some prefabricated U-shaped structures to be cooperated including sand mold body, with bowl configurations to be processed, the connection projection that each prefabricated U-shaped structure is protruded by its surface are embedded in the groove on the sand mold body.The utility model exports quickly by sand wedge angle high temperature, so as to solve the problems, such as casting shrinkage cavity shrinkage porosity and scab caused by sand wedge angle thermal center.
Description
Technical field
It the utility model is related to casting technology field, and in particular to a kind of sand core structure for the casting of sand wedge angle position.
Background technology
Casting pit, especially inner chamber, molding sand produce sand wedge angle, and molten iron baking sand wedge angle temperature is especially high, casts herein
Part is influenceed by sand wedge angle high temperature, final set and cannot get molten iron feeding and produce shrinkage cavity shrinkage porosity, such a phenomenon adds rising head not solve
Certainly.
The content of the invention
In view of the defects of prior art, the utility model proposes a kind of sand core structure for the casting of sand wedge angle position, its
Sand wedge angle high temperature can be allowed to export quickly, so as to solve the problems, such as casting shrinkage cavity shrinkage porosity and scab caused by sand wedge angle thermal center.
To reach above-mentioned purpose, the technical solution of the utility model is the sand core structure for the casting of sand wedge angle position, its
Some prefabricated U-shaped structures to be cooperated including sand mold body, with bowl configurations to be processed, each prefabricated U-shaped structure pass through it
The connection projection that surface protrudes is embedded in the groove on the sand mold body.
Further, the prefabricated U-shaped structure is used for the bowl configurations for manufacturing magnesium iron pulley circumference, some prefabricated Us
Type structure is set along pulley die cavity circumference.
Further, the connection projection in the prefabricated U-shaped structure is by away from one laterally closer sand mold body of sand mold body
Gradually broaden.
Further, the prefabricated U-shaped structure is that the section of embedded pit to be processed is U-shaped chill.
Further, the prefabricated U-shaped structure is that the section of embedded pit to be processed is U-shaped coke briquette.
Using casting technique of the present utility model, it is comprised the following steps that：
Step 1：Some chill structures that manufacture and bowl configurations to be processed cooperate；
Step 2：Pre-buried some chill structures during coremaking；
Step 3：Cast.
The beneficial effects of the utility model：Sand wedge angle high temperature is allowed to export quickly, so as to solve caused by sand wedge angle thermal center
Casting shrinkage cavity shrinkage porosity and scab problem.

Embodiment
The technical scheme of this patent is described in more detail with reference to embodiment.
Using casting technique of the present utility model, its its comprise the following steps that：
Step 1：Some prefabricated U-shaped chill structures that manufacture and bowl configurations to be processed cooperate；
Step 2：During coremaking, some chill structures pre-buried first are respectively along the pit circumference of pulley die cavity 4；Secondly centre bore
Within and around lay chill 5；
Step 3：Poured into a mould by sprue 6.
The utility model proposes the sand core structure cast for sand wedge angle position, and as shown in Figure 1 and Figure 2, it includes sand mold sheet
Body 1, some prefabricated U-shaped structures 2 to be cooperated with bowl configurations to be processed, each prefabricated U-shaped structure 2 are protruded by its surface
Connection projection 3 be embedded in the groove on the sand mold body.
Further, the prefabricated U-shaped structure 2 is used to manufacture the bowl configurations on magnesium iron pulley circumference, if described intervene
U-shape structure processed is set along the circumference of pulley die cavity 4, as shown in Figure 1.
Further, the connection projection 3 in the prefabricated U-shaped structure 2 is by away from 1 one laterally closer sand mold sheet of sand mold body
Body 1 gradually broadens, as shown in Figure 2.
Further, the prefabricated U-shaped structure 2 is that the section of embedded pit to be processed is U-shaped chill.
Further, the prefabricated U-shaped structure 2 is that the section of embedded pit to be processed is U-shaped coke briquette.
The better embodiment of this patent is explained in detail above, but this patent is not limited to above-mentioned embodiment party
Formula, can also be on the premise of this patent objective not be departed from one skilled in the relevant art's possessed knowledge
Various changes can be made.
