Description
Technical field
The utility model discloses the strong release mechanism of a kind of back-off, divides belong to technology of die manufacturing field by International Patent Classification (IPC) (IPC).
Background technology
Present product structure design becomes increasingly complex, the product that some back-off amounts are few can not carry out core_pulling demoulding with the mould structure of routine, strong de-back-off just becomes a kind of reasonably demoulding scheme, program key is for de-back-off creates the space of plastic resilient distortion by force, generally by strong ejecting mechanism de-back-off by force, current ejecting mechanism to be often assemblied on die and to coordinate spring reset to complete, and the long-time spring that uses easily lost efficacy, and can not realize the effect taking off by force back-off.
Summary of the invention
For the deficiencies in the prior art, the utility model provides the strong release mechanism of a kind of back-off.
For achieving the above object, the utility model is achieved through the following technical solutions:
The strong release mechanism of a kind of back-off, comprise moving platen, moving platen is provided with die and slide block insert, die has die cavity, slide block insert horizontal reciprocating is in the die cavity of die, moving core is provided with in die below slide block insert, this core forms goods back-off end in die cavity, thimble fixed head, Ejector Retainer Plate and rear pattern plate is provided with successively below moving platen, described moving core is through die, moving platen, thimble fixed head, Ejector Retainer Plate and extend to rear pattern plate, and moving core is provided with the shoulder hole slot fit bottom chuck and moving platen.
Further, the described shoulder hole notch at moving platen is provided with gripper shoe, and moving core realizes spacing up and down through this gripper shoe, and the chuck of moving core forms back-off and ejects spacing in gripper shoe and moving platen hole slot.
Further, described moving core is connected with block by alignment pin in the bottom of Ejector Retainer Plate, and this block is arranged in the hole slot of Ejector Retainer Plate.
The utility model aims to provide new mould moving core and ejects and homing action stroke controlling structure, and when die sinking product just ejects, product back-off encloses moving core motion and departed from mold cavity, makes it to obtain plastic deformed space; Then moving core is spacing firmly by moving platen, and product continues to eject just the back-off forced stripper mechanism wrapping in moving core; Before matched moulds, moving core is first retracted reset by ejector retainner plate, does not interfere, moving platen designs the injection pressure that gripper shoe carrys out movable support core when guaranteeing matched moulds with other motions.The utility model ejects and the actuating length resetted by controlling moving core, back-off plastic cement is made to obtain the space of elastic deformation and then carry out forced stripper mechanism smoothly, limited and the product mold that back-off amount is little of application space, has and saves the advantages such as space and die cost, having stable behavior be reliable.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Embodiment: refer to Fig. 1 to Fig. 4, the strong release mechanism of a kind of back-off, particularly be applied in the moving core mechanism that rear mold takes off by force back-off, comprise moving platen 1, moving platen 1 is provided with die 2 and slide block insert 3, die 2 has die cavity and forms product M, slide block insert 3 horizontal reciprocating is in the die cavity of die, moving core 4 is provided with in die below slide block insert 3, this core forms goods back-off end in die cavity, under moving platen, 1 face is provided with thimble fixed head 5 successively, Ejector Retainer Plate 6 and rear pattern plate 7, described moving core 4 is through die 2, moving platen 1, thimble fixed head 5, Ejector Retainer Plate 6 and extend to rear pattern plate 7, moving core 4 is provided with the shoulder hole slot fit bottom chuck 41 and moving platen.Be provided with gripper shoe 8 at the shoulder hole notch of moving platen 1, moving core realizes spacing up and down through this gripper shoe, and the chuck of moving core forms back-off and ejects interval S in gripper shoe and moving platen hole slot.Moving core is connected with block 9 by alignment pin 91 in the bottom of Ejector Retainer Plate, and this block 9 is arranged in the hole slot of Ejector Retainer Plate.
The utility model general principle:
As shown in Figure 5, after die sinking, moving core 4 ejects together along with product, after product M ejects 6mm (back-off ejects the concrete enforcement value of interval S), moving core 4 is just blocked by moving platen 1 and cannot continue to move ahead, at this moment back-off plastic cement has departed from mold cavity and has had the space of elastic deformation, and then product continues to be ejected, and back-off has just departed from moving core because of plastic resilient distortion; Before matched moulds, moving core 4 is first retracted reset by Ejector Retainer Plate, and when ensure that matched moulds, slide block insert does not interfere with moving core, and the gripper shoe on moving platen has propped up moving core no longer toward dynamic model lateral movement.
The utility model is through accurate Calculation, design, eject and the actuating length resetted by controlling moving core, back-off plastic cement is made to obtain the space of elastic deformation and then carry out forced stripper mechanism smoothly, for limited space and the little product structure of back-off amount, the moving core structure that this rear mold takes off by force back-off is exactly good a kind of mode, namely save space and die cost, make again having stable behavior reliable, have very large promotion prospect.
Above, be only the embodiment utilizing this origination techniques content, the modification that any those skilled in the art use this creation to do, change, all belong to the scope of the claims that this creation is advocated, and be not limited to those disclosed embodiments.
