Bar 63 and then moves obliquely, and lower link 63 drives lower loose piece 20 inwardly to move by the way that lower guideway 42 is parallel on lower guideway seat 41 again
It is dynamic, complete the lower inside core pulling action of loose piece 20.
After the completion of the inside core pulling action of upper loose piece 10 and lower loose piece 20, plunger tip is moved upwards by plunger tip support rod 91,
Lower roof plate 92 and lower push rod 93 move up plunger tip along guide post 94, complete plunger tip movement.
And mould assembling action of the invention is just opposite with above-mentioned steps.
Compared with prior art, cold box die of the present invention, in sand core molding, lateral surface and sand core it is interior
Side matches, and in sand core demoulding, drive loose piece and lower loose piece sliding above and below respectively by upper pulling mechanism and lower pulling mechanism
It is slided in rail mechanism, to successively drive upper loose piece and lower loose piece to central reduction, so that sand core takes with separating on the inside of sand core
Convenient and efficient out solves the problems, such as the sand core demoulding taking-up that there is muscle in inside.Furthermore cold box die of the present invention, passes through
Sand core type chamber is cooperatively formed between cold-box upper mold, cold-box lower die and internal core-pulling mechanism, by being formed after shooting case of core maker sand
Sand core can fast and effeciently eject sand core under the action of post rod mechanism, so that there is the sand core of muscle structure in inside
Production is efficiently convenient, improves productivity effect.
The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to protection of the invention
Range.
