【Detailed ways】

Please refer to Fig. 1, Fig. 2 and Fig. 3 at the same time. In this embodiment, the delayed mold opening mechanism of the present utility model is applied in a mould. 110. Female template 120, female mold core 130, male mold insert 140, push plate 150, male template 160 and lower fixing plate 170, the delayed mold opening mechanism includes:

The shifting block 200, one end of which is fixed on one side of the mother template 120, the shifting block 200 is provided with a receiving groove 220, and the end of the receiving groove 220 is provided with a protruding block 210, and the protruding block 210 is provided with a first slope 211;

Block 300, one end of which is arranged in the push plate 150, and a corresponding accommodation space is provided in the push plate 150 for the block 300 to be located therein, and the other end of the block 300 protrudes from the push plate 150, extending The end of the push plate 150 is provided with a second inclined surface 330, the second inclined surface 330 has the same inclination angle as the first inclined surface 211, and an elastic element 310 is arranged between the stopper 300 and the push plate 150 in the horizontal direction. , in this embodiment, the elastic element 310 is a spring. When the mold is opened, the shift block 200 moves the block 300 through the bump 210 to make it completely retreat into the push plate 150, so that the mold is opened. In addition The block 300 is provided with a draw-in slot 320 , and a limit screw 321 is vertically provided between the draw-in slot 320 and the push plate 150 to limit the block 300 and prevent the block 300 from breaking away from the push plate 150 ;

Locking block 400, one end of which is fixed on one side of the male template 160, the other end is arranged in the receiving groove 220, and the end of the receiving groove 220 is provided with a hook block 410, and the hook block 410 clamps the The block 300, the hook block 410 is disengaged from the block 300 when the mold is opened;

The pull rod 500 passes through the lower fixed plate 170, the male template 160 and the push plate 150, and the lower fixed plate 170, the male template 160 and the push plate 150 are provided with a corresponding accommodation space for the pull rod 500 to pass through. One end of the pull rod 500 is fixed in the female mold core 130, and the other end of the pull rod 500 is clamped in the push plate 150 when the mold is opened, so as to fix the push plate 150 and stop its movement.

When the mold is opened, the first mold opening and the second mold opening are the same as the ordinary three-platen mold, that is, the stripping plate 110 is separated from the mother template 120 to separate the product 600 from the flow channel during the first mold opening, and the second time When the mold is opened, the stripping plate 110 is separated from the upper fixing plate 100 to peel off the runner from the mould.

Please refer to shown in Fig. 4, when the mold is opened for the third time, the male template 160 continues to move, because the hook block 410 of the locking block 400 blocks the block 300 so as to be locked together with the block 300, so that the male template 160 and the block 300 are locked together. The push plate 150 cannot be separated, so that the male template 160 and the push plate 150 move away from the female template 120 together, and the tight force of the product 600 makes the product 600 and the female mold core 130 separate and stay on the male mold insert 140, and the product 600 is separated. mold.

Please refer to shown in Figure 5, when the mold is opened for the fourth time, the male template 160 and the push plate 150 continue to move, and when the other end of the pull rod 500 is stuck in the push plate 150, the push plate 150 completes the movement stroke and stops moving; The interaction between the first inclined surface 211 and the second inclined surface 330, the bump 210 of the shifting block 200 shifts the block 300, the elastic element 310 is compressed, and the block 300 is completely retracted under the action of the bump 210 of the shifting block 200 into the push plate 150; and the hook block 410 of the locking block 400 is no longer stuck to the block 300, so that the locking block 400 and the block 300 are disengaged, and the male template 160 is separated from the push pedal 150; the male template 160 continues to move until the male template 160 After the mold insert 140 and the product 600 are completely demoulded, the fourth mold opening of the mold is completed; after the product 600 is separated from the male mold insert 140, the product 600 is taken out.

Compared with the prior art, the delayed mold opening mechanism of the present utility model controls the mold opening sequence by moving the stopper through the dial when producing tube products, and the delayed mold opening mechanism can save the male mold core. , Corner pads and ejection mechanism, simple structure.
