Specific embodiment
The present invention will be further illustrated below in conjunction with specific embodiments.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction
Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
It please the appended claims limited range.
The embodiments of the present invention is related to a kind of locking structure for preventing oil cylinder mandril from falling back for die casting,
As shown in Fig. 1-3, including mold core 1, core pulling 3 and die holder 2,1 side of mold core is equipped with die holder 2, in the die holder 2
The core pulling 3 that one end is inserted into mold core 1 across die holder 2 is installed, is pacified side by side before and after the die holder 2 and 1 position opposite side of mold core
Equipped with take-up housing 5, the sliding block 4 that one end is connected with core pulling 3, take-up housing 5 and installation mold core 1 are installed between two take-up housings 5
It sets opposite side and oil cylinder 7 is installed, the mandril 6 of oil cylinder 7 is inserted between two take-up housings 5 and is connected with the other end of sliding block 4,
The connector 9 of the mandril 6 is disposed with the T-slot 8, T to match with connector 9 using cake bulge-structure on sliding block 4
The vertical position of type groove 8 and 6 diameter of mandril match, and laterally the width in a word hole is greater than the thickness of connector 9, the connector
9 are connected with installation with one end of the latch 13 on sliding block 4, and the latch 13 is slidably mounted on 4 upper surface of sliding block, lock
Side is symmetrically installed with the locking mandril 11 in longitudinal sliding motion, described 11 one end of locking mandril and lock before and after the other end of stops 13
13 side Xiang Ding of stops, the other end are embedded into take-up housing 5.
The other end end front and back sides of the latch 13 have been arranged symmetrically arc notch 12.
One end that the locking mandril 11 is embedded in take-up housing 5 uses curved end structure, is disposed with and locks on take-up housing 5
The only arc groove 10 that 11 curved end of mandril matches.
Embodiment
When mould core pulling 3 encounters the pressure being discharged in die cavity, due to the mode locking of latch 13 and locking mandril 11
Power can effectively avoid the mandril 6 of oil cylinder 7 from retracting because of pressure, and when die sinking, the mandril 6 of oil cylinder 7 contracts
Return, since mandril 6 is connected with latch 13, mandril 6 is retracted so that latch 13 is mobile towards 7 direction of oil cylinder, and T-slot 8 with connect
There is the space centainly moved between connector 9, until when locking fast 13 between two locking mandrils 11 from when abjection, connector
9 could slide with movable slider 4, and one end of locking mandril 11 is corresponding with arc notch 12 at this time, when sliding block 4 is toward 7 direction of oil cylinder
When mobile, two locking mandrils 11 are drawn close, and entire core pulling 1 is extracted out.
