Embodiment
With reference to specific embodiment, the utility model is expanded on further.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 is to be understood that reading the content of the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values equally fall within this Shen
Please appended claims limited range.
Embodiment of the present utility model is related to a kind of multi-point pulled core structure for compression mod, as shown in Fig. 1-2,
Including sliding block 5, core_pulling pole 7 and press strip 6, the described middle part of press strip 6 is provided with sliding block 5, one end of sliding block 5 and the main shaft 3 of oil cylinder 1
It is connected, the described front and back position of sliding block 5 is symmetrically installed with some core_pulling poles 7, upper end court and the oil cylinder 1 of described core_pulling pole 7
The opposite direction in position is tilted, and the described lower end of core_pulling pole 7 is embedded in sliding block 5, and described core_pulling pole 7 is located at close to press strip 6
Opening position.
Described main shaft 3 is connected by shaft coupling with sliding block 5.
Described main shaft 3 is provided with gag lever post installation set 4 on one end of sliding block 5, and the described top of main shaft 3 is laterally pacified
The gag lever post 8 being connected equipped with one end with the upper end of gag lever post installation set 4, the other end of described gag lever post 8 are placed through on oil cylinder 1
The positioning seat 10 of end face.
Described gag lever post 8, which is located on the position of the top of oil cylinder 1, is provided with two spacing rings being arranged side by side 9, described
Two limit switches 11 corresponding with spacing ring 9 are installed on the upper surface of oil cylinder 1.
The described bottom of press strip 6 is provided with backing plate 12.
Described oil cylinder 1 is provided with oil cylinder fixed block 2 on one end of sliding block 5.
Embodiment
When the promotion core pulling of oil cylinder 1 is started, oil cylinder 1 starts so that sliding block 5 slides in press strip 6, while promotes and take out
Core bar 7 so that core_pulling pole 7 is inserted into the die cavity of mould, is leaned on until the spacing ring 9 close to the end of 1 main shaft of oil cylinder 3 touches
During a limit switch 11 contact of the nearly main shaft 3 of oil cylinder 1, the stop motion of oil cylinder 1.
