It is described opening 1 with it is described opening 28 opening size be it is identical, it is described opening 28 sides on the limit plate 9
Positioned at the ipsilateral of 28 sides of the opening, it is slidably connected between the snap-gauge 7 and the upper plate 4 and the lower plate 5, and
The snap-gauge 7 is located at the side of the die ontology 1, and there are gaps between the snap-gauge 7 and the die ontology 1, work as mold
It is easy to produce stomata when production, by being internally provided with exhaust block 28 in die ontology 1, improves gas in Mold Making
The discharge in hole avoids generating bubble in casting, the cleaning of this exhaust block 28 so that being able to carry out deceleration when mould material
Simple effects are good, advantage also simple, at low cost with structure.By the collection slag section 30 being arranged on exhaust block 28, so that pouring
The impurity generated when note can concentrate in slag section 30, when needing to clear up exhaust block 28, without clear
Wavy braking section is managed, collection slag section 30 need to be only cleared up, not only simplify cleaning process and reached better cleaning effect again.
In conclusion by means of above-mentioned technical proposal of the invention, by pressing pressing board 2 15 and pressing board 3 16, so that branch
Upper cover plate 2 and lower cover plate 3 are blocked under the blocking for acting on limited block 2 24 and limited block 3 26 of column 2 23 and pillar 3 25, is prevented
Only upper cover plate 2 and lower cover plate 3 generate the phenomenon that displacement in casting process, when needs need upper cover plate 2 and lower cover plate 3 to dismantle
When, it is only necessary to pressing board 1 is pressed, so that the limited post 1 on pressing board 1 slides into pair in opening 1 and opening 28
9 bottom of limit plate answered and limit plate 9 are clamped, then, since limited post 4 13 and limited post 5 11 are in the effect of spring 2 14
Under, so that snap-gauge 7 moves on lower plate 5, so that limited post 2 19 and limited post 3 20 divide with corresponding limit plate 9
From so that pressing board 2 15 and pressing board 3 16 rebound upwards under the action of spring 1, so as to pressing board 2 15 and pressing board
3 16 extraction upper plates 4 and lower plate 5, so that upper plate 4 and lower plate 5 and die ontology 1 separate, and when upper plate 4 is under
When bottom plate 5 is separated with die ontology 1, upper cover plate 2 can be dismantled arbitrarily with lower cover plate 3, greatly facilitate upper cover plate 2 under
The functionality of the disassembly and assembly of cover board 3 facilitates the processing and fabricating of mold.
In addition, stomata is easy to produce when mold is in production, by being internally provided with exhaust block in die ontology 1
28, the discharge of stomata in Mold Making is improved, so that being able to carry out deceleration when mould material, avoids producing in casting
Anger bubble, this exhaust block 28 clean the advantage that simple effects are good, also have structure simple, at low cost.By on exhaust block 28
The collection slag section 30 of setting enables the impurity that generates when casting to concentrate in slag section 30, when needing to exhaust block 28
When cleaning, without clearing up wavy braking section, collection slag section 30 need to be only cleared up, not only simplifies cleaning process again
Better cleaning effect is reached.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
