Specific implementation mode
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 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 embodiment of the utility model is related to a kind of mandril withdrawing pulled core structure for die casting, such as 2 institutes of Fig. 1-
Show, including top plate 1, fixed plate 6 and cope plate 5,1 lower face of top plate is equipped with fixed plate 6,6 lower face of fixed plate peace
Equipped with cope plate 5,5 lower face of cope plate is equipped with upper die holder 7, and upper mold core 11, the upper mold are equipped in 7 lower end of upper die holder
The core-pulling slide block 4 to horizontally slip is installed, 4 top of core-pulling slide block is vertically-mounted to have upper end to pass through upper mold in 11 right end of core
The withdrawing mandril 2 of seat 7, cope plate 5 and fixed plate 6,2 upper end of withdrawing mandril are fixed on top plate 1, withdrawing mandril 2
Lower end is disposed with lower end towards right-oblique withdrawing brace 3.
Side is equipped with press strip 12 before and after the core-pulling slide block 4, and the press strip 12 is close to 4 side transverse direction cloth of core-pulling slide block
It is equipped with sliding slot 13.
Vertically-mounted in the upper die holder 7 to have limited post 9,9 lower end of limited post is corresponding with core-pulling slide block 4, institute
The left side for the limited post 9 stated is bonded with the right side of upper mold core 11.
It is vertically-mounted on the lower die holder of 9 lower section of limited post to have anti-rivet corresponding with limited post 9 10.
There are spacing between the right end and the lower end of limited post 9 of the core-pulling slide block 4.
The vertically-mounted locating pin 8 for thering is lower end to be inserted into lower die holder in the upper die holder 7.
The diameter of the upper die holder 7, cope plate 5 and fixed plate 6 installed bore dia and be more than withdrawing mandril 2, it is described
