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 to the formative method of a kind of casting molding box and this molding box.
Background technology
A most important ring is mould assembling process to foundry goods in process of production, and mould assembling quality is directly connected to the foundry goods made and is dividing
Globality at type face.Therefore mould assembling process should play the effect preventing mo(u)ld bottom half in die joint movement.Traditional mould assembling process
The purpose fixing typically merely by realizing mo(u)ld bottom half cooperation in the method that mo(u)ld bottom half placing box is bored.But the foundry goods that this kind of method is made is easy
At die joint position, dislocation occurs.Also there are some producers to release in recent years and lengthened molding box cone, case cone two ends were lengthened to reduce conjunction
Mould shift occurs during case.But the method still suffers from many weak points: (1) increased case cone weight, and mould assembling working strength increases
Plus；(2) case cone is still shorter with respect to upper and lower molded dimension, needs many people to be directed at mould assembling from different perspectives, process is loaded down with trivial details simultaneously；(3)
If mo(u)ld top half carries more casting form, mould assembling process has apperance clashing and breaking in the event of dislocation, makes foundry goods defect.Therefore go up
State in method due to case cone stroke change less, mould assembling process difficulty is big and upper mo(u)ld bottom half die joint mould shift problem does not obtain
Improve.
Content of the invention
An object of the present invention, for the problems referred to above present in existing molding box mould assembling, provides a kind of band guiding
The molding box of bar case cone, is misplaced with die joint during preventing molding box mould assembling.
The above-mentioned purpose of the present invention is achieved in that a kind of molding box of guide case cone, including top case and mo(u)ld bottom half
Case, at the die joint of described top case and drag box, the molding box of one of them is provided with several guide cases cone, another molding box
It is correspondingly provided with the internal taper hole with the guiding cone match of guide case cone, described guide case cone center is provided with pilot hole at die joint
One, it is correspondingly provided with the pilot hole two coaxial with pilot hole one, described pilot hole one and guiding in the molding box that described internal taper hole is located
In hole two, guiding cooperation is provided with mould assembling guide post, and the length of described mould assembling guide rod is more than the height of the corresponding molding box of pilot hole two
Degree.
Beneficial effect using molding box structure of the present invention is: by being equipped with pilot hole on top case and drag box
First, pilot hole two and mould assembling guide rod, during mould assembling, mould assembling guide rod passes through pilot hole two in advance and coordinates importing pilot hole one,
Make to shift to an earlier date guide-localization during the mould assembling of top case whereabouts, and under the guide effect of mould assembling guide rod and pilot hole two, top case continues
Continuous whereabouts accurately mould assembling, misplace during effectively preventing mould assembling, improve the quality of molding box mould assembling, and prevent damage during mould assembling
Bad apperance.
As the improvement of the present invention, described pilot hole two runs through place molding box, and described mould assembling guide post runs through pilot hole
Two, and mould assembling guide post one end extends into pilot hole one, and the other end stretches out pilot hole two place molding box.Before mould assembling, this
Bright mould assembling guide post fits in pilot hole two in advance, and during mould assembling, another external part fits into guide case cone first
Pilot hole one, then proceedes to mould assembling process, and the position of upper drag box shifts to an earlier date along guide direction mould assembling, effectively prevents die joint wrong
Position.
Imported in pilot hole one with guide post accurate fit for ease of mould assembling during mould assembling, described mould assembling guide post stretches into leads
One end of Xiang Kongyi is provided with the taper chamfering being easy to guide, and another external part of described mould assembling guide post is vertically provided with pin.
