Abstract
The utility model relates to a suspended core structure of a water jacket sand core of a diesel engine cylinder head, which comprises the water jacket sand core and an upper positioning core print, wherein the upper positioning core print is lengthened and the center part of the upper positioning core print is reserved with a slot hole, so that the water jacket sand core has smooth ventilation and accurate positioning when in casting. Therefore, a water stuffing hole is omitted, the problem of water leakage of a diesel engine is reduced, as for cylinder head manufacturing enterprises, the processing procedures and processing hours of the cylinder head are reduced, the first-phase preparation for manufacturing the cylinder head is reduced, clamps and special cutters are omitted, and the production efficiency and quality of the cylinder head are improved.
Description
Technical field
The utility model relates to a kind of suspended core structure of core, especially the suspended core structure of diesel engine cylinder cover sand core of water jacket.
Background technology
The general employing has the vexed hole of water technology in the casting technique of one-cylinder diesel cylinder cap at present.Effects such as the vexed hole of water technology plays location, exhaust in casting, shake out have been continued to use for many years in the production of reality, and technology is also ripe relatively.But find in using that diesel engine work can take place to leak because of the water stifle comes off to cause often, main cause is to increase afterwards corresponding water vexed hole processing and the vexed hole processing of the setting-out two procedures of having increased in the vexed hole of water.Traditional handicraft needs thick hinge to finish ream two procedures, two positioning fixtures, two bench drills and two employees when the vexed hole of process water, has correspondingly increased the regular maintenance and the maintenance of special purpose machine tool.For this reason, diesel engine manufacturing enterprise proposes the vexed hole of cancellation water, but is subjected to the restriction of casting technique, also do not have advanced technologies to replace original cylinder cap production technology, so the vexed hole of water technology is used till today always.
The utility model content
Technical problem to be solved in the utility model provides a kind of suspended core structure that does not need the diesel engine cylinder cover sand core of water jacket in the vexed hole of water.
The technical scheme in the invention for solving the technical problem is: a kind of suspended core structure of diesel engine cylinder cover sand core of water jacket, comprise sand core of water jacket and last location core print, and locate the length of core print on the lengthening, and stay slotted hole in the heart portion of last location core print.
The following location of adopting said structure just to cancel core only depends on the location core print of going up of core that sand core of water jacket is fixed on the sand mold, and during the mould assembly cast, the buoyancy of molten iron withstands on sand core of water jacket on the sand mold, has so just cancelled the vexed hole of water of diesel engine cylinder cover.Realize this purpose, the length that goes up the location core print of lengthening diesel engine sand core of water jacket, and stay slotted hole in the heart portion of last location core print makes sand core of water jacket unobstructed and accurate location of exhaust when pouring into a mould.The vexed hole of cancellation water technology in the casting technique of one-cylinder diesel cylinder cap, not only reduce the seepy question of diesel engine, concerning cylinder cap manufacturing enterprise, the manufacturing procedure and the machining period of cylinder cap have been reduced, the corresponding expenses such as cylinder cap process equipment and cutter that reduce, reduce the preliminary preparation that cylinder cap is produced, cancelled anchor clamps and dedicated tool, improved the production efficiency and the quality of cylinder cap.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
1, sand core of water jacket 2, on locate core print 3, slotted hole
The specific embodiment
The suspended core structure of a kind of diesel engine cylinder cover sand core of water jacket shown in Figure 1, comprise sand core of water jacket 1 and last location core print 2, the length of location core print 2 on the lengthening, and stay slotted hole 3 in the heart portion of last location core print 2 makes sand core of water jacket 1 unobstructed and accurate location of exhaust when pouring into a mould; Adopt hot-box core making process, the location core print 2 of going up of sand core of water jacket 1 is the notes sand hole, after finishing notes sand, insert thimble from annotating the sand hole top, thimble gos deep in the sand core of water jacket 1, during delivery, withdraw from thimble earlier, form the slotted hole 3 of locating on the core print 2 of going up of sand core of water jacket 1, mo(u)ld bottom half on separately, take out sand core of water jacket 1, finish the manufacturing of location sand core of water jacket 1.Only depend on the location core print 2 of going up of sand core of water jacket 1 that sand core of water jacket 1 is fixed on the sand mold, during the mould assembly cast, the buoyancy of molten iron withstands on sand core of water jacket 1 on the sand mold, so just cancelled the vexed hole of water of diesel engine cylinder cover, reduce the preliminary preparation that cylinder cap is produced, cancel anchor clamps and dedicated tool, improved the production efficiency and the quality of cylinder cap.
