Detailed description of the invention
Fig. 1-4 are structure and working principle key diagram of the present invention; As shown in Figure 1, a kind of mould secondary ejects template clutch control mechanism, comprises slotting door bolt 1, lock box block 2, movable lock dog 3, spring 4, lock box block screw 5, inserts door bolt screw 6.
As shown in Figure 2, described slotting door bolt 1, lock box block 2, movable lock dog 3 are respectively installed in three pieces of different templates of an order discharge; Described slotting door bolt 1 is installed on mould template by inserting door bolt screw 6; Lock box block 2 is installed on mould template by lock box block screw 5; Movable lock dog 3 is installed in mould template with spring 4; Insert door bolt 1 one end and be designed with screw, for installing, one end is designed with trapezoidal eave tile in addition, controls purposes for locking; Lock box block 2 middle part offers vertical groove, coordinates with slotting door bolt 1, and middle part laterally offers trapezoidal groove, for controlling movable lock dog 3; Movable lock dog 3 is ladder activities block; In Fig. 2, B-B sectional view is known, and the width S 1 of movable lock dog 3 is greater than the vertical groove width S 2 offered lock box block 2 middle part;
As shown in Figure 3, described a kind of mould secondary ejects template clutch control mechanism needs the separation carried out between the template of die sinking separation to control on mould;
Further, for ease of being described mechanism of the present invention, need be stated by mould auxiliary spare part of being correlated with, as Fig. 3 (a), 3(b) shown in, relevant auxiliary component is: counterdie seat board (7), thimble push plate (8), ejector retainner plate trip bolt (9), thimble cover plate (10), secondary thimble push plate (11), secondary thimble cover plate (12), secondary ejector retainner plate trip bolt (13); During mold work, a thimble push plate (8) and a thimble cover plate (10) are combined into one piece of integral slab by an ejector retainner plate trip bolt (9), are called a plate; Secondary thimble push plate (11) and secondary thimble cover plate (12) are combined into one piece of integral slab by secondary ejector retainner plate trip bolt (13), are called secondary plate; The installation situation of mechanism of the present invention is: lock box block 2 is installed on counterdie seat board (7) by lock box block screw 5, and movable lock dog 3, spring 4 are installed on an aforementioned plate, inserts door bolt 1 and is installed on aforementioned secondary plate by inserting door bolt screw 6; Further, for ease of the motion control situation of mechanism of the present invention is described, as as shown in Fig. 3 (a), Fig. 3 (c), choose K, L, M, N as representing control point, wherein: K is the control point on the middle position on the trapezoidal eave tile in slotting door bolt 1 bottom, L is the control point on movable lock dog 3 ramp on middle position, and M is the control point that horizontal trapezoid groove inclined-plane, lock box block 2 middle part can contact with movable lock dog 3, N be on movable lock dog 3 can with of a M point cantact control point.
When the present invention applies in a mold, concrete use principle is as follows:
1) mechanism of the present invention is installed on situation on mould as shown in Fig. 3 (a), Fig. 3 (b), and application controls principle as shown in Figure 4, from the needs of injection mold Double-ejection, when ejecting, counterdie seat board (7) is by relative to not moving, what need moving movement is a plate and secondary plate, when its sequence of motion is for ejecting, counterdie seat board (7) maintains static, injection machine push rod first head on secondary plate by mechanism controls of the present invention with a plate move right together, after certain distance to be moved, mechanism action of the present invention, secondary plate is made to lose motive force to a plate, one time plate departs from secondary plate and comes to a halt, secondary plate continues to move ahead, thus the ejecting function that product ejects by realization at twice,
2) concrete corresponding state of a control analytic process is as follows:
2.1), after before ejecting motion, state mold injection completes, prepare die sinking, each part status as shown in Figure 4 (a), now, movable lock dog 3 is ejected by spring 4, and its head stretches out outside a template, just in time caught on by the trapezoidal eave tile of slotting door bolt 1, ensure that combining closely of a plate and secondary plate;
2.2) prepare to unblank as shown in Figure 4 (b), injection machine push rod heads on secondary plate and moves right, trapezoidal eave tile due to slotting door bolt 1 has caught on movable lock dog 3, thus, a plate will by secondary strip and move right together, after moving to certain distance, the M point on horizontal trapezoid groove inclined-plane, lock box block 2 middle part is by the N point on compressing activity lock dog 3, and the resistance forcing movable lock dog 3 to overcome spring 4 moves inward;
2.3) unblank as shown in Figure 4 (c), a plate continues to move ahead to the right together with secondary plate, when movable lock dog 3 is pressed into after in a plate completely, the trapezoidal eave tile inserting door bolt 1 catches on effect by losing to movable lock dog 3, thus making secondary plate lose pulling force to a plate, secondary plate continues to move ahead, and a plate then rests on state position shown in Fig. 4 (d), product ejects from mold cores by secondary plate by continuation, as shown in Fig. 4 (d);
2.4) mechanism resets from Fig. 4 (d), when mould resets, secondary plate will with slotting door bolt 1 together to left movement, and after the K point inserted on door bolt 1 crosses L-N-M point, secondary plate will fit together with a plate, secondary plate will push a plate together to left movement, until be returned to state as shown in Figure 4 (a), now, insert door bolt 1 to be ejected by spring 4, again caught on by the trapezoidal eave tile of slotting door bolt 1, wait for that the next one ejects circulation and starts.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit, those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
