For achieving the above object, technical solution of the present utility model is：

This utility model is a kind of improvement mechanism of mould opening sequence controller, including cover half, dynamic model, swing rod, fork, pin Axle, spring, locating piece, limited block；The upper end of described swing rod is fixed on cover half, and the bottom of swing rod abuts against dynamic model On the wall of side, outside trapezoid boss is provided with the bottom of swing rod；Described locating piece is fixed on the side wall of dynamic model, fork Middle part is hinged on the side wall of dynamic model, and the top of fork is resisted against on locating piece, the lower end inside wall of fork and one end of spring Lean, the other end of spring is acted against on the side wall of dynamic model；Described bearing pin extended transversely through on the top of fork, and bearing pin is passed End be resisted against on swing rod outer wall and can with the trapezoid boss of swing rod bottom against；Described limited block is arranged on the side of dynamic model On wall and with the side wall for abutting against dynamic model on swing rod bottom against.

Described swing rod is made up of left swing pole socket and right swing rod；Described left swing pole socket is parallel with right swing rod, Every setting, locating piece is fixedly mounted between left swing pole socket and right swing rod, is all set in the bottom of left swing pole socket and right swing rod There is outside trapezoid boss；Described fork is located between left swing pole socket and right swing rod, is applied in the bearing pin on fork top Both sides traversing through end bears against on left swing pole socket and right swing rod outer wall and can be with left swing pole socket and the ladder of right swing rod bottom Shape boss against.

After using such scheme, also include limited block as this utility model is additionally arranged, the limited block is arranged on dynamic model On the wall of side and with the side wall for abutting against dynamic model on swing rod bottom against, it is to avoid the bottom of swing rod directly with dynamic model side Wall is against substantially increasing this utility model ruggedness and service life so that this utility model stability is more preferable.

This utility model is further described with specific embodiment below in conjunction with the accompanying drawings.

Specific embodiment

As shown in Figure 1-Figure 3, this utility model is a kind of improvement mechanism of mould opening sequence controller, including cover half 1, dynamic model 2nd, swing rod 3, fork 4, bearing pin 5, spring 6, locating piece 7, limited block 8.

Described swing rod 3 is made up of left swing pole socket 31 and right swing rod 32.Described left swing pole socket 31 and right swing rod The upper end of 32 parallel, interval settings, left swing pole socket 31 and right swing rod 32 is all fixed on cover half 1, left swing pole socket 31 and right pendulum The bottom of pole socket 32 is all abutted against on the side wall of dynamic model 2, is all provided with outside in the bottom of left swing pole socket 31 and right swing rod 32 Trapezoid boss 311,321.Described locating piece 7 is fixed on the side wall of dynamic model 2 and is fixedly mounted on left swing pole socket 31 and right pendulum Between pole socket 32.

Described fork 4 is located between left swing pole socket 31 and right swing rod 32, and the middle part of fork 4 is hinged on the side of dynamic model 2 On wall, the top of fork 4 is resisted against on locating piece 7, and lower end inside wall and one end of spring 6 of fork 4 lean, spring 6 it is another One end is acted against on the side wall of dynamic model 2.

Described bearing pin 5 is extended transversely through on the top of fork 4, is applied in the both sides traversing through end point of the bearing pin 5 on 4 top of fork It is not resisted against on 32 outer wall of left swing pole socket 31 and right swing rod and can be trapezoidal convex with 32 bottom of left swing pole socket 31 and right swing rod Platform 311,321 against.

Described limited block 8 be arranged on dynamic model 1 side wall on and with the side wall for abutting against dynamic model 2 on swing rod 3 under Portion against.

Operation principle of the present utility model：

As shown in Figure 4, Figure 5, during die sinking, described cover half 1 and dynamic model 2 separates, and swing rod 3 slides along 8 surface of limited block. The both sides traversing through end of the bearing pin 5 on 4 top of fork is moved along left swing pole socket 31 and 32 outer wall of right swing rod respectively, when moving to left swing The trapezoid boss 311,321 of 32 bottom of pole socket 31 and right swing rod（As shown in Figure 1）When upper, fork 4 is by trapezoid boss 311,321 Outwards jack-up and make the top of fork 4 depart from locating piece 7.

Emphasis of the present utility model is that：Increased a limited block.

The above, only this utility model preferred embodiment, therefore this utility model enforcement can not be limited with this Scope, i.e., the equivalence changes made according to this utility model claim and description and modification, all should still belong to this reality In the range of being covered with new patent.
