Abstract
The utility model discloses a deslagging exhaust mechanism for die-casting forming of clutches. The deslagging exhaust mechanism comprises a slag bag, overflow grooves are arranged at the outer end of the slag bag, and an exhaust block is arranged at the tail end of each overflow groove and connected with the slag bag through the overflow groove. By the aid of the deslagging exhaust mechanism, intensive air holes formed at far ends of transmission matching surfaces can be eliminated, and the rejection rate of product production is decreased.
Description
Technical field
The utility model belongs to field of metal casting technology, specifically a kind of clutch die cast exhaust gear that removes slag.
Background technology
Clutch is key position parts on the automobile, though its build is little, planform is complicated; Specification requirement is high, and is extremely high to the requirement of pore, the face that wherein cooperates with speed changer; Referring to accompanying drawing 1; The castability of this face requires very high, does not allow to occur any defective, especially pore after the processing.
Fig. 2 is the existing clutch die cast structural scheme of mechanism that removes slag that degass.Clutch is that single face advances to water.Should open cinder ladle away from gate end, with convenient exhaust deslagging.But experiment finds, during die cast, with the speed changer mating surface away from the later arrival of main running channel position aluminium liquid, form volume gas easily, only open cinder ladle herein, can not discharge slag, gas well, gas can appear wrapping up in easily on the contrary.Therefore, existing method for exhausting is for cylinder body exhaust deslagging, and effect is not clearly, with the speed changer mating surface away from main running channel position, large-area pore occurs, and that this face pore requires is high, so casting qualified rate is very low.
Summary of the invention
In order to solve the problems of the technologies described above; The purpose of the utility model provides a kind of clutch die cast exhaust gear that removes slag; Through adopting the novel exhaust gear structure that removes slag, can eliminate the intensive pore of the face far-end appearance of speed changer cooperation, reduce the percent defective of production.
The purpose of the utility model realizes through following technical scheme:
A kind of clutch die cast exhaust gear that removes slag comprises cinder ladle, it is characterized in that: be provided with overflow launder in the cinder ladle outer end, be provided with the exhaust piece at the overflow launder end, the exhaust piece is connected with cinder ladle through overflow launder.
In the utility model, the quantity and the cinder ladle of said overflow launder are suitable, and one group of overflow launder all is connected with the exhaust piece.
The utility model is driven overflow launder in the cinder ladle outer end, opens big exhaust piece at the overflow launder end then, similar vacuumizing, and when aluminium liquid arrived far-end like this, exhaust effect obviously improved, and the quality of foundry goods has also arrived very big improvement.
Adopt the utility model, with the speed changer mating surface away from main running channel position, pore is eliminated or is very little, meets the requirements, moulding is very good, qualification rate also obviously improves a lot.
Description of drawings
Fig. 1 is the surface model figure that cooperates with speed changer.
Fig. 2 is original clutch die cast structural scheme of mechanism that removes slag that degass.
Fig. 3 is the structural representation of the utility model.
The specific embodiment
The described clutch die cast of a kind of the utility model exhaust gear that removes slag is seen Fig. 3, and this mechanism comprises cinder ladle 1, is provided with overflow launder 2 in cinder ladle 1 outer end, is provided with exhaust piece 3 at overflow launder 2 ends, and exhaust piece 3 is connected with cinder ladle 1 through overflow launder 2.The quantity of overflow launder 2 and cinder ladle 1 are suitable to be that quantity is consistent, and one group of overflow launder 2 all is connected with exhaust piece 3.
During the clutch cast molding, aluminium liquid advances to water from a side, with the speed changer mating surface away from main running channel position.When aluminium liquid arrives far-end, can discharge slag, gas earlier from cinder ladle 1, arrive exhaust piece 3 through overflow launder 2, through 3 exhausts of exhaust piece, Forming Quality is obviously improved at last, and pore is eliminated or be very little, meets the requirements, and moulding is very good, and qualification rate also obviously improves a lot.
In addition, the exhaust piece adds original cinder ladle, has increased bed drain purge, during the design of exhaust piece push rod should be arranged, and can eject smoothly.
Claims (2)
