Preferable, the utility model provide a kind of open the matched moulds detent mechanism, wherein, described flexible block assembly also comprises a guide pillar, this guide pillar is arranged at this bottom portion of groove, and this bullet piece is provided with guide groove that should guide pillar, and this flexible member is socketed on this guide pillar.

Preferable, described flexible member is a spring.

Preferable, described block is L shaped.

Preferable, described pulley is circular.

Of the present utility model open the matched moulds detent mechanism have simple in structurely, and can accurately control the die sinking of mould and the sequential scheduling advantage of matched moulds.

The specific embodiment

For describing technology contents of the present utility model, structural feature in detail, illustrated in detail below in conjunction with embodiment and conjunction with figs..

See also Fig. 1, it is a perspective view of the present utility model.This mould comprise master mold 11, intermediate die plate 12, male model 13 and open matched moulds detent mechanism 2, wherein, described open matched moulds detent mechanism 2 comprise: master mold push rod 21, one ends are locked in the side of described master mold 11, and its other end offers breach 211; Male model push rod 22, one ends are locked in the side of described male model 13, and its middle part offers short slot 221; At least two

blocks

24 and 25 are installed on the described intermediate die plate 12, lay respectively at the outside of described master mold push rod 21 and described male model push rod 22; And pulley 23, can left and right displacement be installed on the described intermediate die plate 12, between the inboard of the inboard and described master mold push rod 21 of described male model push rod 22, under the state of mould matched moulds, described pulley 23 is fastened in the short slot 221 at described male model push rod 22 middle parts and the middle part of described master mold push rod 21.

Please cooperate consult shown in Figure 3, it is the cross-sectional view along B-B ' of Fig. 2, also please cooperate in addition and consult shown in Fig. 3 A, described open matched moulds detent mechanism 2 also comprise flexible block assembly 3, in the groove 121 that its corresponding position that is arranged at described male model push rod 22 deformation traces of described intermediate die plate 12 is offered, and this flexible block assembly 3 comprises: bullet piece 31, and it is movably set in this groove 121, and the one end is articulated on the described groove 121; And flexible member 32, in present embodiment, this flexible member 32 is springs, this flexible member 32 is connected between the bottom of the other end of this bullet piece 31 and this groove 121, and in present embodiment, this flexible block assembly 3 also comprises a guide pillar 33, and this guide pillar 33 is arranged at the bottom of this

groove

121,31 of this bullet pieces are provided with guide groove that should guide pillar 33, and this flexible member 32 also is socketed on this guide pillar 33.

See also Fig. 2 again, it is the perspective view under the utility model die opening state.In this, this mould is when die sinking, at first give the power of drawing on the described master mold 11 by crane, after the breach 211 that moves to its lower end when described master mold push rod 21 meets with described pulley 23, certain displacement takes place to the right in the described pulley 23 of described male model push rod 22 compressings, make described intermediate die plate 12 be pulled away from described male model 13, thereby finish the die sinking operation of this mould.

Otherwise, when matched moulds, because described pulley 23 is fastened in breach 211 places of described master mold push rod 21, makes described master mold push rod 21 to move down, along with described intermediate die plate 12 moves down, the short slot 221 that moves to its middle part on the described male model push rod 22 meets with described pulley 23, described master mold push rod 21 will give described pulley 23 1 to the power that moves to left, and make described pulley 23 move in the described short slot 221, in this, described master mold 11 just can move down, thereby finishes the matched moulds operation of mould.

Please continue to cooperate and consult Fig. 3, Fig. 3 A, when the mould die sinking, when described male model push rod 22 is displaced downwardly to when detaching described block 24, described flexible member 32 recovers under the effect of natural elasticities described bullet piece 31 is pushed out to described block 24 and offsets, under the situation of described male model push rod 22, can stop described pulley 23 to move to left.

The above is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model; Every equivalence of doing according to the utility model changes and revises, and is all covered by claim of the present utility model.
