It is plugged in the limiting slot.
Further, the reset sliding block includes position limiting structure, and the side of the position limiting structure is close to the centering block, institute
It is close to the injecting products on the mold other side for stating position limiting structure.
Further, the T-shaped slide rail is equipped with the prominent structure of connection, and the reset sliding block is tied by the way that the connection is prominent
Structure is connect with the T-shaped slide rail.
Further, the T-shaped slide rail is connect with the oil cylinder being arranged on mold.
The present invention cylindrical parts centering block demolding structure, mold die sinking after, by oil cylinder drive reset sliding block along
T-slot moves in a straight line on centering block pedestal, discharges the degree of freedom of centering block, then by by product transverse movement, making plastic-embedded manually
Part bottom beam like features structure touches centering block, touches centering block and does arc track rotation along shaft, pushes product to synchronize and carries out
Demoulding, when centering block rotates to the end of swivelling chute, product stripping is completed.This mechanism simplifying prior art products need along
The axis direction of beam like features structure moves the processing step demoulded, without so that the shift length of product is more than column spy
The demoulding of beam like features structure can be completed in the height of sign structure, simplifies the operation difficulty of site operation personnel, reduces production
The risk that product crack in demoulding, reduces the scrappage of product, reduces production cost, improve production efficiency.

Specific implementation mode
In order to preferably understand technical scheme of the present invention, below by specifically embodiment and in conjunction with attached drawing
It is described in detail:
Please refer to Fig. 5 and Fig. 6, a kind of centering block demolding structure of cylindrical parts of the invention, including centering block 61, centering block pedestal
62, it resets sliding block 71 and resets sliding block pedestal 72, centering block pedestal 62 and reset sliding block pedestal 72 are arranged on mold.
Centering block 61 is arranged on centering block pedestal 62, rotary shaft through hole is offered on centering block 61, centering block is by passing through rotary shaft through hole
Shaft 63 connect with centering block pedestal 62, and can be rotated on centering block pedestal around the shaft.Limiting slot is offered on centering block
64, centering block pedestal 62 is equipped with gag lever post 65, and gag lever post 65 is plugged in limiting slot 64, plays and limited to the displacement of centering block
Effect.
It resets sliding block pedestal 72 to be arranged side by side with centering block pedestal 62, is equipped on resetting sliding block pedestal 62 and resets sliding block 71,
T-type sliding slot is offered on resetting sliding block pedestal 72, T-shaped slide rail 73 is plugged in T-type sliding slot, T-shaped slide rail 73 is equipped with connection
Prominent structure 731 resets sliding block 71 and is connect with T-shaped slide rail 73 by the prominent structure 731 of connection, and T-shaped slide rail 73 can drive reset
Sliding block moves along a straight line along T-type sliding slot.It resets sliding block 71 and is equipped with position limiting structure 74, the side of position limiting structure 74 and centering block
61 are close to, and the other side of position limiting structure 74 is close to the injection-molded item 1 on mold.T-shaped slide rail 73 is connect with oil cylinder 8.
Referring to Fig. 5, after mold die sinking, when not yet proceeding by stripping operation, resets sliding block 71 and centering block 61 is in
Initial position, the side for resetting the position limiting structure 74 of sliding block 71 is close to centering block 61, on the other side and mold of position limiting structure 74
Injection-molded item 1 be close to.Referring to Fig. 7, then oil cylinder is moved, T-shaped slide rail 73 is driven to slide 50mm along T-type sliding slot,
It drives reset sliding block 71 to synchronize to be moved so that position limiting structure 74 discharges the degree of freedom of centering block 61 far from centering block 61.It removes at this time
All component floating 30mm outside lower die.
Referring to Fig. 8, then, operating personnel push product traversing so that the beam like features structure contact pendulum of plastic insert
Block 61 pushes centering block 61 to carry out 63 rotation around the shaft, until the contact injection-molded item 1 of centering block 61, and squeezes injection-molded item and carries out
Synchronous demoulding completes stripping operation until gag lever post 65 touches the terminal of limiting slot 64 at this time.After completing demoulding, centering block 61
