The specific embodiment
Embodiment: a kind of mould opens and closes positioner, and described mould comprises patrix 2, middle mould and counterdie 4, counterdie 4 connection mode pin 5 and fixed-site, and middle mould 3 is positioned at directly over the counterdie 4, and patrix 2 is arranged in directly over the mould 3; Patrix 2 and middle mould 3 vertically move up and down with respect to counterdie 4, it mainly comprises pull bar 1, two struts 6, backstay 7, location matrix 8 and locating piece 9, described two struts 6 each end respectively are articulated in middle mould 3 and counterdie 4, two struts, 6 other ends are hinged, and an end that is hinged is placed in a pull bar 1; Described pull bar 1 upper end is fixed on patrix 2, the lower end is provided with a projection 11 by strut 6 sides, projection 11 just can push against when pull bar 1 rises to certain position in the pin joint of two struts 6, slips over pin joint after continuing to rise, and is positioned at projection 11 opposition sides on the pull bar 1 and is provided with a chamfering; Counterdie 4 is provided with a fixing location matrix 8, location matrix 8 and pull bar 1 are positioned at the same side of mould, the location be movably equipped with on the matrix 8 one can be in the matrix 8 of location to the locating piece 9 of strut 6 direction horizontal slips, and an end of locating piece 9 relative two struts, 6 pin joints establish one with the oblique angle 92 of 1 time chamfer of pull bar coupling, but oblique angle 92 proper elasticity push against in pull bar 1, in the finger, the counterdie closure state, this moment, first projection 91 was in no any state that pushes against, and locating piece 9 center fixed are provided with one first projection 91; Middle mould 3 is provided with the backstay 7 that middle mould 3 is fixed in a upper end, backstay 7 and location matrix 8 are positioned at the same side of mould, backstay 7 activities are placed in locating piece 9 one sides, the groove 71 of one and first projection, 91 couplings is established in backstay 7 lower ends, but first projection 91 proper elasticity when backstay 7 rises to certain position is placed in the groove 71, and first projection 91 pushes against in backstay 7 to strut direction elasticity, in the finger, the counterdie opening, slip over pin joint after pull bar 1 continuation is risen this moment, and oblique angle 92 is in no any state that pushes against.
Described locating piece 9 one ends are connected to location matrix 8 with a screw 93, and overlap a spring 94 on screw, locating piece springing back and forth in the matrix of location.
This routine operating process is as follows: when moving on patrix is vertical, drive on the pull bar and move, pull bar rises to the lower end projection and pushes against when two struts are middle, strut is forced to middle mould and counterdie are strutted, when moving on to certain distance on the pull bar, the elastic force that locating piece is subjected to spring enters the groove of backstay, fixing in the position of mould and counterdie; During matched moulds, pull bar moves down, and the pull bar chamfering pushes against the oblique angle of locating piece, makes the locating piece withdrawal that suffers oppression, and middle mould and counterdie begin to close tightly finishes mould assembling action.
