Abstract
A casting mold device includes a lower die and an upper die capable of being attached to or detached from the lower die and is configured to produce a cylinder head having spark plug mounting portions. In particular, the casting mold device includes: i) a plurality of core pin assemblies mounted in the upper die to form the spark plug mounting portions and having cooling air flow paths formed therein, ii) a cooling unit installed on the upper die and including cooling air inlet portions and cooling air outlet portions respectively connected to the cooling air flow paths of the core pin assemblies, and iii) a sealing unit coupled to the cooling unit and the upper die to seal portions between the core pin assemblies and the cooling unit.
Claims14
A casting mold device comprising:
- a lower die;
- an upper die configured to attach to or detach from the lower die;
- a plurality of core pin assemblies mounted in the upper die and including a plurality of separating pins capable configured to couple to or separate from one another, wherein the plurality of core pin assemblies includes cooling air flow paths formed in the plurality of separating pins coupled to one another;
- a cooling unit installed on the upper die and connected to the cooling air flow paths so as to inject and discharge cooling air;
- and
- a sealing unit coupled to the cooling unit and the upper die to seal portions between the core pin assemblies and the cooling unit,
- wherein the plurality of separating pins each comprise:
- a cylindrical plug casing fitted with a pin insertion hole formed in the upper die in an upward/downward direction, the cylindrical plug casing being opened at upper and lower ends thereof;
- a plug pin fitted with the cylindrical plug casing, coupled to a lower portion of the cylindrical plug casing, opened at an upper end thereof, and closed at a lower end thereof;
- and
- a plug bushing fitted with the cylindrical plug casing so as to be positioned above the plug pin, coupled to an upper portion of the cylindrical plug casing, and having a cylindrical shape opened at upper and lower ends thereof.
