Specific embodiment
Present invention will be further explained below with reference to specific examples.It should be understood that these embodiments are merely to illustrate the present invention
Rather than it limits the scope of the invention.In addition, it should also be understood that, after reading the content taught by the present invention, those skilled in the art
Member can make various changes or modifications the present invention, and such equivalent forms equally fall within the application the appended claims and limited
Range.
Embodiments of the present invention are related to a kind of locking structure for preventing oil cylinder mandril from falling back for die casting, such as scheme
Shown in 1-3, including mold core 1, core pulling 3 and die holder 2,1 side of mold core are equipped with die holder 2, installation in the die holder 2
There is one end to pass through the core pulling 3 that die holder 2 is inserted into mold core 1, has been mounted side by side before and after the die holder 2 and 1 position opposite side of mold core
Take-up housing 5 is equipped with the sliding block 4 that one end is connected with core pulling 3, take-up housing 5 and installation 1 position phase of mold core between two take-up housings 5
Oil cylinder 7 is equipped with to side, 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, described
Mandril 6 connector 9 using cake bulge-structure, the T-slot 8 to match with connector 9, T-slot are disposed on sliding block 4
8 vertical position 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 with
Installation is connected 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, locking
Side is symmetrically installed with the locking mandril 11 in longitudinal sliding motion, described 11 one end of locking mandril and locking before and after the other end of block 13
13 side Xiang Ding of block, the other end are embedded into take-up housing 5.
