Description

Casting machine height-regulating structure

Technical field

It the utility model is related to casting bucket displacement structure, more particularly to a kind of casting machine height-regulating structure.

Background technology

During molding sand is used as mould, production metal casting, molding sand is first made into sand mo(u)ld, then pour into sand mo(u)ld Ingot metal molten liquid.Casting metals molten liquid is poured into sand mo(u)ld frequently with casting bucket.

At present, the Chinese patent of Publication No. CN202224645U discloses a kind of casting machine, its operation principle is：By Cylinder promotes one end of casting bucket so that casting bucket motion state is similar with lever principle, and casting bucket tilts, by casting bucket Point molten metal is poured into mould.But in this pushing structure, the vertical height between ground is not all the time for the center of bucket of casting Become, so when more mold exchange, mold height change, easily make to contradict between casting bucket and mould, influence to cast The course of work for toppling over point molten metal of bucket.

Utility model content

The purpose of this utility model is to provide a kind of casting machine height-regulating structure, can adjust the vertical height of casting bucket, and And it is not easy to make opposite collision occurs between casting bucket and casting line.

The above-mentioned technical purpose of the utility model technical scheme is that：

A kind of casting machine height-regulating structure, including rack, bucket body, are equipped with bracket at the bucket body, the bracket and rack it Between be equipped with lifting device, described lifting device one end is connected with bracket, is flexibly connected between the other end and frame top.

By using above-mentioned technical proposal, lifting device drives bracket to move up and down, and bracket can play bucket body protection Effect, meanwhile, there is not the part that is connected with casting line between lifting device and bracket and casting line independently of each other, so bucket body is transported During dynamic, the influence of casting line is not easily susceptible to, only lifting device drives, and on the premise of stress is single, is not easy to send out naturally Situations such as raw offset, collision.

Further set：The lifting device includes leading screw, nut, and the leading screw is set perpendicular to bracket, the nut It is arranged on leading screw, and is located at frame top.

By using above-mentioned technical proposal, leading screw and nut relative motion, nut are located at frame top, and relative position is motionless On the premise of, drive leading screw to move up and down, leading screw drives bracket to move up and down, and realizes the purpose for the vertical height for adjusting bucket body.

Further set：The lifting device further includes motor, and the output shaft of the motor is vertically arranged, the motor Transmission belt is equipped between output shaft and nut.

By using above-mentioned technical proposal, motor drives nut rotation, in the drive mechanism of nut and leading screw, if nut turns Dynamic, then leading screw need to only move up and down without rotating, so leading screw can drive bracket to move up and down, and due to being not required to Rotate, therefore be not easy to cause bracket damage caused by moment of torsion.

Further set：The leading screw is arranged at the both sides of bracket, and the nut described in both sides on leading screw is by same motor Driving.

By using above-mentioned technical proposal, leading screw can be uniformly applied on bracket for the power that bracket is applied, and made Obtain bracket held stationary during rising or falling.

Further set：The vertical height of nut on the leading screw of both sides is in multiple proportion.

By using above-mentioned technical proposal, since both sides nut is driven by same motor, so the nut of both sides and electricity The relation of the output shaft of machine should be that the position of one of nut is top, and the position of another nut is on the lower.When erecting for nut After straight height is set in multiple proportion, the relative position of nut at two can be made as far as possible reliable, play is not easy to reach nut Purpose.

Further set：The nut includes embedment spacing section of housing top wall, exposes transmission segment outside housing top wall.

By using above-mentioned technical proposal, spacing section is used for stop nut, reduces the possibility of nut play, transmission belt is then For nut to be connected with the piston rod of motor.

Further set：Described spacing section is equipped with bearing between housing top wall.

By using above-mentioned technical proposal, nut in rotation process, bearing can effectively reduce spacing section with roof it Between frictional resistance.

Further set：The transmission segment is arranged to " work " font, and the transmission belt falls the recess in transmission segment.

By using above-mentioned technical proposal, transmission belt during the motion, is not easy to come off from transmission segment.

Further set：The lifting device further includes guide post, and described guide post one end is fixed on bracket, and the other end runs through Frame top.

By using above-mentioned technical proposal, guide post is used for spacing and guiding role so that bracket is during the motion all the time Keep stablizing, be not easy the state tumbled.

In conclusion the utility model has the advantages that：Effective and rapidly bucket body can be driven to move up and down, and And since bucket body is also subject to the spacing and protective effect of bracket, so bucket body is not easily susceptible to external influence during the motion, And the upward stroke of leading screw is big, bucket body can be driven to away from mould, so as to reach reduce bucket body and mold impingement can Can property.
