Description
Technical field
The utility model belongs to core manufacture auxiliary equipment field, and in particular to a kind of plunger tip plate and die sinking sychronisation.
Background technology
Core is the material for being used in Foundry Production manufacture core, is made up of casting model powder, moulding sand binder etc..Core is used
In various fields, such as the water channel of cylinder cap is typically made up of core.
Core shooter is generally all used when manufacturing core, the production efficiency of this core shooter is high, and core shooter injects molding sand
The core cavity of lower template and then the hydraulic cylinder of lower template bottom push up lower template so that lower template and cope plate are combined,
And then by core compaction moulding and then go out core.
There is problems with prior art：Cope plate and lower template are moved respectively when die sinking, can so be led
Core when die sinking is caused by unbalanced pulling force, to cause the quality of core breakage influence core.
Utility model content
The purpose of this utility model is to provide a kind of plunger tip plate and die sinking sychronisation so that cope plate is with during die sinking
Template can be moved simultaneously, allow core in die sinking above and below the pulling force that balances, it is to avoid the quality of core breakage influence core.
To reach above-mentioned purpose, basic technology scheme of the present utility model is to provide a kind of plunger tip plate dress synchronous with die sinking
Put, including the cope plate and lower template that can be pressed under the effect of outside hydraulic power system, cope plate upper surface is installed with
Plunger tip plate, plunger tip plate is provided with the push rod that may pass through plunger tip plate, and the bottom surface of lower template and the top surface of plunger tip plate are separately installed with
The end of connecting rod and lower link, upper connecting rod and lower link is separately installed with upper cross plate and lower cross plate, the bottom surface of upper cross plate and lower horizontal stroke
The both side ends of the top surface of plate are installed with drive link；The end of drive link is provided with roller；The biography of upper cross plate and lower cross plate
Rotate to be provided with synchronous disk, synchronous disk between lever and symmetrical cam is installed.
During using such scheme, cope plate and lower template realize laminating, upward mould by the effect of external hydraulic dynamical system
Sand is injected in space after plate and lower template laminating, and sand forms core in this space and then carries out heating plastic to core,
Core shapes after the completion of plasticity.The demoulding is now needed, lower template is promoted through plunger tip plate first by push rod during the demoulding so that on
Split at the pressing of template and lower template；Then, synchronous disk is started, synchronous disk, which is rotated, can drive symmetrical cam rotation, symmetrically
Cam athletic meeting the drive link while drive link being connected with upper cross plate is moved up on lower cross plate is moved down；And
And drive link is moved according to the track of cam, the linear velocity that both move is identical；The mobile of drive link can drive upper cross plate
With lower cross plate motion, cope plate and lower template can be simultaneously when upper cross plate and the simultaneously synchronized reverse movement of lower cross plate realize die sinking
It is mobile, allow core in die sinking above and below the pulling force that balances, it is to avoid the quality of core breakage influence core.
Drive link reaches the limit of position when the preferred scheme 1 that the improvement to base case is obtained, cope plate and lower template pressing
Put；So that transmission is more accurate.
The preferred scheme 2 that improvement to base case is obtained, push rod passes through the Driven by Hydraulic Cylinder installed in plunger tip plate surface；
Hydraulic stem has good power.
The preferred scheme 3 that improvement to base case is obtained, the rotating speed of synchronous disk is less than 5cm/s, and rotating speed is too fast to be caused
Core is easily damaged during die sinking.
Brief description of the drawings
Fig. 1 is the utility model plunger tip plate and the structural representation of die sinking sychronisation embodiment.
Embodiment
The utility model is described in further detail below by embodiment and reference：
Reference in Figure of description includes：Cope plate 1, lower template 2, plunger tip plate 3, push rod 4, upper cross plate 5, lower horizontal stroke
Plate 6, drive link 7, roller 8, synchronous disk 9, cam 10.
Embodiment is substantially as shown in Figure 1：A kind of plunger tip plate and die sinking sychronisation, including can be in outside hydraulic power system
The cope plate 1 and lower template 2 of the lower pressing of system effect, the upper surface of cope plate 1 are installed with plunger tip plate 3, and plunger tip plate 3 is provided with can
Through the push rod 4 of the push rod 4 of plunger tip plate 3, the bottom surface of lower template 2 and the top surface of plunger tip plate 3 are separately installed with upper connecting rod and lower company
The end of bar, upper connecting rod and lower link is separately installed with upper cross plate 5 and lower cross plate 6, the bottom surface of upper cross plate 5 and the top of lower cross plate 6
The both side ends in face are installed with drive link 7；The end of drive link 7 is provided with roller 8；The transmission of upper cross plate 5 and lower cross plate 6
Rotate to be provided with synchronous disk 9, synchronous disk 9 between bar 7 and symmetrical cam 10 is installed.Cope plate 1 and lower template 2 are pressed
Drive link 7 reaches the limit of position during conjunction；Push rod 4 passes through the Driven by Hydraulic Cylinder installed in the surface of plunger tip plate 3；The rotating speed of synchronous disk 9
Less than 5cm/s.
Implementation principle：Cope plate 1 and lower template 2 realize laminating by the effect of external hydraulic dynamical system, to the He of cope plate 1
Sand is injected in space after lower template 2 is fitted, and sand forms core in this space and then carries out heating plastic, plasticity to core
After the completion of core shape.The demoulding is now needed, lower template 2 is promoted through plunger tip plate 3 first by push rod 4 during the demoulding so that on
Split at the pressing of template 1 and lower template 2；Then, synchronous disk 9 is started, synchronous disk 9, which is rotated, can drive symmetrical 10 turns of cam
Dynamic, the symmetrical athletic meeting of cam 10 causes the transmission while drive link 7 being connected with upper cross plate 5 is moved up on lower cross plate 6
Bar 7 is moved down；And drive link 7 is moved according to the track of cam 10, and the linear velocity that both move is identical；Drive link 7
It is mobile upper cross plate 5 and lower cross plate 6 can be driven to move, the simultaneously synchronized reverse movement of upper cross plate 5 and lower cross plate 6 realizes die sinking
When cope plate 1 and lower template 2 can move simultaneously, allow core in die sinking above and below the pulling force that balances, it is to avoid core breakage influence sand
The quality of core.
