Description
Technical field
This utility model relates to core making machine field, particularly a kind of core making machine top mold frame oil cylinder synchronization mechanism structure.
Background technology
In the design of oil cylinder lazy-tongs, conventional mode is: 1. synchronization framework, rack-and-pinion synchronizing shaft add other valve groups；
2. mechanical synchronization, syncmotor, synchronous valve add other valve groups；3. mechanical synchronization, proportioning valve add other valve groups；4. mechanical synchronization,
Servo valve adds other valve groups.Cutting both ways, precision, cost are stepped up.More than in actual applications often according to concrete operating mode general
Several ways is applied in combination.But the control mode that conventionally employed synchronization framework and proportioning valve add other valve groups has the disadvantage in that
Owing to frame strength is weak, the connection of cylinder piston rod and top mold frame body with articulated form, runs up and down and often occurs bearing
Carry swing, cylinder piston rod disengages with framework connection place, seals the phenomenons such as fragile.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of core making machine top mold frame oil cylinder synchrodrive
Tool structure, present application addresses that the load caused owing to oil cylinder is asynchronous is rocked, cylinder piston rod and framework connection place disengage, close
Seal the phenomenons such as fragile.
The purpose of this utility model is achieved through the following technical solutions: a kind of core making machine top mold frame oil cylinder synchrodrive
Tool structure, including cylinder piston rod, spherical bearing joint, remodeling connecting plate and top mold frame body, described top mold frame body includes
It is installed on the side wing of top mold frame body both sides, bottom side wing, forms arcuate bottom with top mold frame body bottom portion by the same centre of sphere
Face, side wing top and top mold frame body are positioned at same level line, and described remodeling connecting plate is installed on top mold frame body, remodeling
Connecting plate is provided with two fixing flanges, and spherical bearing joint is inserted between two fixing flanges, and by bolt with remodeling even
Fishplate bar activity is fixed, and spherical bearing joint is also equipped with cylinder piston rod.
In this utility model, due to two oil cylinder resistances when traditional core making machine top mold frame oil cylinder synchronization mechanism structure is run
Power, speed has certain difference, when an oil cylinder speed is accelerated, and the cylinder piston rod being attached thereto has change in various degree
Shape, running resistance becomes inconsistent, at this moment can cause pressure that oil cylinder carries and flow to whole synchronization mechanism structure the most
Fluctuation, causes whole cylinder piston rod reciprocally swinging to deform.
Preferably, the bearing pivot angle α that cylinder piston rod operationally drives spherical bearing joint to be formed is 4 °, is conducive to subtracting
The effect of the power produced during small oil tank piston rod movement, thus reduce the deformation of cylinder piston rod.
Preferably, being additionally provided with base bottom remodeling connecting plate, base through screws is fixed with top mold frame body, is conducive to increasing
Add the stability of whole frame for movement.
The beneficial effects of the utility model are:
(1) use remodeling connecting plate and spherical bearing joint to substitute old connecting plate, utilize the axle of spherical bearing joint about 4 °
Hold pivot angle and reduce piston rod deformation；
(2) reduce the running resistance of oil cylinder, reduce the frequency of maintenance of oil cylinder key position, with low cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is traditional synchronization mechanism structural representation；
In figure, 10-top mold frame body, 20-side wing, 30-bolt, 40-retrofits connecting plate, 50-cylinder piston rod, 60-
Spherical bearing joint, 70-connecting plate.
Detailed description of the invention
The technical solution of the utility model is described in further detail below in conjunction with the accompanying drawings, but protection domain of the present utility model
It is not limited to the following stated.
As it is shown in figure 1, a kind of core making machine top mold frame oil cylinder synchronization mechanism structure, including cylinder piston rod 50, spherical bearing
Joint 60, remodeling connecting plate 40 and top mold frame body 10, described top mold frame body 10 includes being installed on top mold frame body 10 both sides
Side wing 20, bottom side wing 20 with top mold frame body 10 bottom by the same centre of sphere formed lower arcuate surface, side wing 20 top
Being positioned at same level line with top mold frame body 10, described remodeling connecting plate 40 is installed on top mold frame body 10, connecting plate of retrofiting
40 are provided with two fixing flanges, and spherical bearing joint 60 is inserted between two fixing flanges, and are connected with remodeling by bolt
Plate 40 is movable fixing, and spherical bearing joint 60 is also equipped with cylinder piston rod 50.
In this utility model, as in figure 2 it is shown, traditional core making machine top mold frame oil cylinder synchronization mechanism structure includes top mold frame
Body 10, top mold frame body 10 both sides are provided with side wing 20, and the top horizontal position of side wing 20 is less than top mold frame body 10
Top horizontal position, top mold frame body 10 is provided with connecting plate 70, and connecting plate 70 is fixed with oil cylinder piston by bolt 30
Bar 50, has certain difference due to two oil cylinder resistances, speed when this core making machine top mold frame oil cylinder synchronization mechanism structure is run,
When an oil cylinder speed is accelerated, and the cylinder piston rod 50 being attached thereto has deformation in various degree, running resistance to become to differ
Causing, pressure and flow that oil cylinder at this moment can be caused to carry to whole synchronization mechanism structure have fluctuated, and cause whole oil cylinder to be lived
Stopper rod 50 reciprocally swinging deforms.
Preferably, the bearing pivot angle α that cylinder piston rod 50 operationally drives spherical bearing joint 60 to be formed is 4 °, favorably
The effect of the power produced in time reducing cylinder piston rod 50 and move, thus reduce the deformation of cylinder piston rod 50.
Preferably, being additionally provided with base bottom remodeling connecting plate 40, base through screws is fixed, favorably with top mold frame body 10
In the stability increasing whole frame for movement.
