Abstract
The invention relates to a casting box with a guide rod box cone and a casting method of the casting box in the technical field of casting. The casting box with the guide rod box cone comprises an upper casting box and a lower casting box; multiple guide box cones are arranged on one of the parting surfaces of the upper and lower casting boxes; inner conical holes matched with the guide conical surfaces of the guide box cones are correspondingly formed in the other parting surface of the upper and lower casting boxes; a guide hole I is formed in the center of each guide box cone; a guide hole II coaxial with the guide hole I is correspondingly formed in the casting box in which the inner conical hole is formed; a guide rod for box closing is arranged in the guide hole I and II in a guide matching manner; the length of the guide rod for box closing is greater than the height of the casting box corresponding to the guide hole II. According to the casting box structure, during the process of closing the upper and lower boxes, the upper casting box enter a guide position in advance; dislocation during box closing is effectively prevented by virtue of the matching guide action of the guide rod for box closing and the guide hole II; a mold core and a casting cavity are prevented from being damaged; thus the casting quality of the casting box is improved.
Description
Technical field
The present invention relates to casting technology field, particularly a kind of formative method cast with molding box and this molding box.
Background technology
A foundry goods in process of production most important ring is mould assembling process, and mould assembling quality is directly connected to the globality of foundry goods at die joint place of making.Therefore mould assembling process should play the effect preventing mo(u)ld bottom half in die joint movement.Traditional mould assembling process generally realizes mo(u)ld bottom half and coordinates fixing object by means of only the method for boring at mo(u)ld bottom half placing box.But easily there is dislocation at die joint position in the foundry goods that this kind of method is made.Also there were some producers to release in recent years and lengthened molding box cone, and case was bored two ends and lengthen to reduce to occur mould shift in mould assembling process.But still there is many weak points in the method: (1) adds case cone weight, and mould assembling working strength increases; (2) case cone is still shorter relative to upper and lower molded dimension, and need many people to aim at mould assembling from different perspectives, process is loaded down with trivial details simultaneously; (3) if mo(u)ld top half is with more casting form, if dislocation occurs mould assembling process have apperance clashing and breaking, foundry goods is made to occur defect.Therefore the stroke change due to case cone in said method is little, and the large and upper mo(u)ld bottom half die joint mould shift problem of mould assembling process difficulty does not improve.
Summary of the invention
An object of the present invention, for the problems referred to above existed in existing molding box mould assembling, provides the molding box that a kind of guide case is bored, to prevent die joint dislocation in molding box mould assembling process.
