There are two pieces of core-pulling slide blocks, multi-direction guide mechanism, the multi-direction slide guide machine are provided on the sliding block and the core-pulling slide block
Structure includes the moving die insert being fixed on the dynamic model, and the top surface of the moving die insert is in isosceles triangle, bottom surface in isosceles ladder
Shape is formed with insert guide runner on the two sides inclined-plane of the moving die insert, and the core-pulling slide block is in tri-prismoid, and the core pulling is sliding
The wherein one side of block is fixed with insert slider guide, and structure and insert guide runner cooperation are formed on the insert slider guide
Insert slide plate, the another side of the core-pulling slide block are formed with sliding block guide runner, and the sliding block is close to the end of the moving die insert
There are two sliding block inclined-plane, the side that the sliding block inclined-plane is formed with sliding block guide runner with the core-pulling slide block cooperates wheat flour, and described two
It is fixedly installed with sliding block slider guide on a sliding block inclined-plane, structure is formed on the sliding block slider guide and is matched with the sliding block guide runner
The sliding block slide plate of conjunction.
In above-mentioned technical proposal, wearing plate is provided between the two sides inclined-plane and the core-pulling slide block of the moving die insert.
In above-mentioned technical proposal, the insert pressure for preventing the insert slide plate from falling off is fixed on the insert guide runner
Item, the cell wall outer end of the sliding block guide runner are formed with the step for preventing the sliding block slide plate from falling off.
Compared with prior art, core-pulling mechanism of the invention can realize the core pulling of different directions, especially core pulling direction phase
Core pulling when mutual chiasma interference meets and is limited by space and multiple core-pulling mechanisms can not be arranged in when core pulling direction chiasma interference
Multi-angle core pulling demand.
