Cylinder cup type chamber is arranged side by side, and the axle center of the cylinder cup type chamber is located along the same line；By thin between the two cylinder cup type chambers
The hot core of piece separates, and the hot core of thin slice is fixed on the cold core ontology.Jacket core of the invention had both had cold core size
The advantage that precision is high, deformation is small, high-efficient, and have hot core intensity high, it can be avoided the advantage of thin slice area deformation, effectively solve
The larger problem of cylinder body water jacket core difference in thickness of having determined, has given full play to the advantage of cold core process Yu hot core technique, has avoided technique
Limitation, influence production efficiency by water-jacket core structure problem.
Cup structure is solid mould steel among existing cylinder body water jacket hot box, farther out away from core box ontology heating tube, because
Conduction efficiency is inadequate, and the temperature of technique requirement is not achieved in temperature in production herein, causes sand core solidification insufficient, so necessary
Extend curing time, thus reduces production efficiency.For this patent structure using the structure for inlaying copper rod among cup, enhancing is intermediate
Heat conduction efficiency between cup and core box ontology improves temperature herein, solves the problems, such as production.
Summary of the invention
The purpose of the present invention is to provide a kind of structures of novel reinforcement casting chaplet box conduction efficiency, to solve above-mentioned back
Cup structure is solid mould steel among the existing cylinder body water jacket hot box that proposes in scape technology, away from core box ontology heating tube compared with
Far, because conduction efficiency is inadequate, the temperature of technique requirement is not achieved in temperature in production herein, and sand core is caused to solidify insufficient, institute
Curing time must be extended, thus the problem of reduce production efficiency.
The purpose of the present invention and effect are reached by technological means in detail below:
A kind of structure of novel reinforcement casting chaplet box conduction efficiency, wherein the novel reinforcement casting chaplet box conduction effect
The structure of rate includes upper core box ontology, upper core box cup mounting groove, upper core box cup and copper rod fixation hole；The upper core box sheet
Upper core box cup mounting groove at six is offered on the upside of body；The inside insertion of the upper core box cup mounting groove is mounted with six
Locate upper core box cup.
Further, eccentric copper rod fixation hole is offered on the upper core box cup, and is inlayed inside copper rod fixation hole
It is provided with thermally conductive copper rod, and thermally conductive copper rod need to be tight in copper rod fixation hole.
Further, vacuum hardening processing need to be carried out when the upper core box cup hair is processed pah.
In comparison with existing structure, the invention has the following beneficial effects:
Using after this structure, the temperature at cylinder body water jacket hot box cup is significantly improved, and the sand core produced is not consolidated
Change bad phenomenon, improves the coremaking efficiency of sand core, improve the quality of sand core.And it is opened up on the upper core box cup being equipped with
There is eccentric copper rod fixation hole, and is inlayed inside copper rod fixation hole and be provided with thermally conductive copper rod, and thermally conductive copper rod need to be tight at copper
In stick fixation hole, which inlays big copper rod in copper rod fixation hole in the upper core box cup of solid mould steel construction, favorably
In increasing heat conduction efficiency, the local temperature for effectively improving mold reaches technique requirement, thus improving production efficiency.
