Reasonablely be: leave the gap of 0.01mm between aperture plug of the present invention and the left core box to 0.4mm.
Reasonablely be: the present invention is provided with roller respectively at the two ends that strand connects the bearing pin of first toggle and second toggle.
Beneficial effect: the present invention adopts technique scheme, compared with prior art has following advantage:
1, the invention solves the problem of the direct die sinking difficulty of deep hole at shape small column position on the core, core qualification rate height.
2, the present invention adopts first toggle and second toggle strand ways of connecting, prevents to occur when cold-box injection sand the problem of bloated mould.
3, the present invention is a mechanical connection manner, and motion is reliable, stable.
4, the present invention can realize the die sinking of core smoothly, guarantees the integrality of core; Do not need core is repaired, improved the qualification rate of product.
5, core qualification rate of the present invention is very high, has improved production efficiency, has reduced cost.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Have among the above figure: aperture plug 1, left core box 21, right core box 22, left side sealing frame 31, right sealing frame 32, the first toggles 4, support column 5, base plate 6, the second toggles 7, Connection Block 8, oil cylinder 9, roller 10, carve type piece 11, connecting plate 12, top board 13, pressing plate 14, fixture 15.
The specific embodiment
Below in conjunction with accompanying drawing technical scheme of the present invention is described in detail:
As shown in Figure 1, the present invention includes base plate 6, left side core box 21, right core box 22, oil cylinder 9, left side sealing frame 31, right sealing frame 32, aperture plug 1, connecting plate 12, described left core box 21, right core box 22 is arranged on the base plate 6, aperture plug 1 is arranged between left core box 21 and the right core box 22, the arranged outside left side sealing frame 31 of left side core box 21, the right sealing of the arranged outside of right core box 22 frame 32, sealing frame 31 in a left side is connected oil cylinder 9 by connecting plate 12 respectively with right sealing frame 32, it is characterized in that: also comprise differential die opening mechanism, four differential die opening mechanisms are evenly arranged in left core box 21 respectively, the outside of right core box 22, described differential die opening mechanism comprises first toggle 4, support column 5, second toggle 7, Connection Block 8, roller 10, wedge 11, fixture 15, support column 5 is arranged on the base plate 6, the upper end of support column 5 is provided with first toggle 4 respectively, second toggle 7, be connected by the bearing pin strand between first toggle 4 and second toggle 7, the two ends of bearing pin are provided with roller 10 respectively; First toggle 4 is connected by fixture 15 between the frame with sealing, twists between first toggle 4 and the fixture 15 to be connected; Second toggle 7 is connected with base plate 6 by Connection Block 8, and second toggle 7 is connected with the upper end strand of Connection Block 8; With on the corresponding connecting plate 12 in roller 10 positions wedge 11 is set, an end of wedge 11 broads is connected with connecting plate 12.
