Abstract
The present invention is a kind of can accurately to fix the mould for metal casting of core, including upper mould, a screw and No. two screws；Lower mould is buckled with below upper mould；The core of circle is nested between upper die and lower die；Above core and side is provided with die cavity with the place that upper die and lower die join；Below core product sand launder is provided with the junction of lower mould；Sand core internal is fixed on upper mould provided with circular iron core, iron core with the lower end of No. two screws from lower moulds；Iron core lower end level is embedded with three metal uniformly laid pilot pins, and each metal pilot pin is fixed on core interior with a screw from lower end.A described screw is flat head screw.No. two described screws are soket head cap screw.Present invention novelty simple in construction, stablizes durable, internal cores are difficult to fix when solving metal casting, the problem of easy core floatation, and by the application of the program, casting dimension qualification rate brings up to 99.5% by original 70%, and effect is clearly.
Description
Technical field
The present invention relates to field, more particularly to a kind of it can accurately fix the mould for metal casting of core.
Background technology
Common metal mould casting process is in casting process, and core stability is poor, is difficult to fix because buoyancy is moved, can make
There are relatively large deviation, the qualification rate reduction of casting, cost increase, benefit reduction into casting dimension.
The content of the invention
The present invention is difficult to the fixed problem asked to solve the core of mould for metal casting, and providing one kind can accurately consolidate
Determine the mould for metal casting of core.
The present invention can accurately fix the mould for metal casting of core there is provided a kind of to achieve the above object, including upper mould,
A number screw and No. two screws；Lower mould is buckled with below upper mould；The core of circle is nested between upper die and lower die；Above core
Die cavity is provided with the place that side and upper die and lower die join；Below core product sand launder is provided with the junction of lower mould；In core
Portion is fixed on upper mould provided with circular iron core, iron core with the lower end of No. two screws from lower moulds；Iron core lower end level is embedded with three
The individual metal pilot pin uniformly laid, each metal pilot pin is fixed on core interior with a screw from lower end.
A described screw is flat head screw.
No. two described screws are soket head cap screw.
The beneficial effects of the invention are as follows：It is of the present invention it is a kind of can accurately fix the mould for metal casting of core, knot
Structure is simply novel, stablizes durable, on during use without any additional operations and influence, internal cores when solving metal casting
It is difficult to fix, the problem of easy core floatation, by the application of the program, casting dimension qualification rate is brought up to by original 70%
99.5%, effect is clearly.
Brief description of the drawings
Fig. 1 is a kind of structural representation of metal casting core fixing device of the present invention；
Wherein：The upper moulds of 1-；Mould under 2-；3- cores；4- metal pilot pins；Number screw of 5-；No. bis- screws of 6-；7- iron cores；
8- die cavities；9- accumulates sand launder.
Embodiment
It is described in detail referring to the drawings below with reference to embodiments of the invention.
It is a kind of accurately to fix the mould for metal casting of core, including upper mould 1, a screw 5 and No. two screws 6；On
Mould 1 is buckled with lower mould 2 below；The core 3 of circle is nested between upper mould 1 and lower mould 2；Above core 3 and side with upper mould 1 and
The place that lower mould 2 joins is provided with die cavity 8；Core 3 is provided with product sand launder 9 with 2 junctions of lower mould below；The inside of core 3 is provided with circle
The iron core 7 of shape, iron core 7 is fixed on upper mould 1 with the lower end of No. two screws 6 from lower mould 2；The lower end level of iron core 7 is embedded with three
The metal pilot pin 4 uniformly laid, each metal pilot pin 4 is fixed on inside iron core 7 with a screw 5 from lower end.
A described screw 5 is flat head screw.
No. two described screws 6 are soket head cap screw.
During metal casting, upper mould 1 is opened, core 3 is in place in iron core 7, be rotated further by 15~60 ° of angles, this
When three metal pilot pins 4 depict depth about 0.5~1mm horizontal channel in the inwall of core 3, it is to avoid core is about 3
Mobile, the sand fallen down during delineation falls in product sand launder 9, it is ensured that then the bottom locating surface of core 3, closes mould 1 without burning into sand,
Molten metal is injected in die cavity 8, after solidification, mould 1 in opening, from the interior ejection metal casting of lower mould 2.
