Abstract
The utility model relates to a mould for metal founding that can accurate fixed psammitolite, including last mould, a screw and no. Two screws, the knot has the lower mould below going up the mould, upward the nestification has the circular shape psammitolite between mould and the lower mould, the higher authority of psammitolite and the place of side and last mould and lower mould handing -over are equipped with the die cavity, handing -over department with the lower mould below the psammitolite is equipped with long -pending sand groove, the inside circular shape iron core that is equipped with of psammitolite, the iron core is fixed on last mould from the lower extreme of lower mould with no. Two screws, the embedding of iron core lower extreme level has the three metal pilot pin of evenly laying, and every metal pilot pin is fixed inside the iron core from the lower extreme with a screw. A screw be pan head screw. No. Two screws be soket head cap screw. The utility model has the advantage of simple and novel structure, stabilize durablely, inside psammitolite is difficult to fix when having solved the metal founding, the problem of easy core floatation, and through the application of this scheme, foundry goods size qualification rate brings up to 99.5% by original 70%, and the effect is very obvious.
Description
Technical field
The utility model relates to field, particularly relates to a kind of mould for metal casting accurately can fixing core.
Background technology
Common metal mould casting process is in casting process, and core poor stability, is difficult to because buoyancy moves fix, and casting dimension can be caused to have relatively large deviation, and the qualification rate of foundry goods reduces, and cost increases, and benefit reduces.
Summary of the invention
The utility model is difficult to a difficult problem of fixedly asking in order to the core solving mould for metal casting, and provides a kind of mould for metal casting accurately can fixing core.
The utility model for achieving the above object, provides a kind of mould for metal casting accurately can fixing core, comprises patrix, a screw and No. two screws; Counterdie is buckled with below patrix; Circular core is nested with between upper die and lower die; The place that above core and side and upper die and lower die join is provided with die cavity; Long-pending sand launder is provided with the junction of counterdie below core; Sand core internal is provided with circular iron core, and iron core No. two screws are fixed on patrix from the lower end of counterdie; Iron core lower end level is embedded with three metal pilot pins evenly laid, and each metal pilot pin screw is fixed on core interior from lower end.
A described screw is flat head screw.
No. two described screws are soket head cap screw.
The beneficial effects of the utility model are: a kind of mould for metal casting accurately can fixing core described in the utility model, structure is simply novel, stablize durable, on in use procedure without any additional operations and impact, when solving metal casting, internal cores is difficult to fix, and the problem of easy core floatation, by the application of the program, casting dimension qualification rate brings up to 99.5% by original 70%, and effect clearly.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of metal casting core fixture described in the utility model;
Wherein: 1-patrix; 2-counterdie; 3-core; 4-metal pilot pin; 5-screw; 6-No. bis-screws; 7-iron core; 8-die cavity; 9-amasss sand launder.
Detailed description of the invention
Be described in detail with reference to accompanying drawing below with reference to embodiment of the present utility model.
Accurately can fix a mould for metal casting for core, comprise patrix 1, screw 5 and No. two screws 6; Patrix 1 is buckled with counterdie 2 below; Circular core 3 is nested with between patrix 1 and counterdie 2; The place that above core 3 and side and patrix 1 and counterdie 2 join is provided with die cavity 8; Core 3 is provided with long-pending sand launder 9 with 2 junctions of counterdie below; Core 3 inside is provided with circular iron core 7, and iron core 7 No. two screws 6 are fixed on patrix 1 from the lower end of counterdie 2; Iron core 7 lower end level is embedded with three metal pilot pins 4 evenly laid, and each metal pilot pin 4 screw 5 is fixed on iron core 7 inside from lower end.
A described screw 5 is flat head screw.
Described No. two screws 6 are soket head cap screw.
During metal casting, patrix 1 is opened, core 3 is in place in iron core 7, rotate 15 ~ 60 ° of angles again, at this moment three metal pilot pins 4 depict the horizontal channel of a dark about 0.5 ~ 1mm at core 3 inwall, avoid core 3 and move up and down, the sand fallen down during delineation drops in long-pending sand launder 9, guarantee that core 3 bottom locating surface is without burning into sand, then, close patrix 1, molten metal is injected in die cavity 8, after solidification, open patrix 1, in counterdie 2, eject metal casting.
