[0020] Further, the width of the delay gap 17 is 2mm, and the rear reset action of the sliding block 2 is realized by the small delay gap 17.
[0021] In the above scheme, due to the delay gap 17 and the ejecting spring 11, the rear reset during mold reset and the preferential ejection during mold release can be realized, and the oil cylinder 12 sliding block 2 delay mold has the advantages of simple structure, avoiding damage to the injection molding insert, high injection molding yield, and prolonging the service life of the insert.
[0022] Taking the injection flange plate as an example, two groups of lower mold inserts 3, upper mold inserts 1 and sliding blocks 2 are arranged on the lower mold plate 4 and the upper mold plate 5, and the lower mold plate 4, the lower mold plate 4, the lower mold insert 3, the upper mold insert 1 and the sliding block 2 form a flange plate forming cavity after being combined, each group of lower mold inserts 3 and upper mold inserts 1 are connected to the same lower mold plate 4 and lower mold plate 4 respectively, and each group of sliding blocks 2 is connected to the same side pushing plate 6, the lower mold plate 4 and the lower mold plate 4 are connected to the output end of the press respectively, the sliding block 2 on the inner side of the side pushing plate 6 is inserted into the mold cavity of the lower mold plate 4 through the side surface sliding hole of the lower mold plate 4, the middle part of the outer side of the side pushing plate 6 is provided with a T-shaped groove 7, the two sides of the outer side of the side pushing plate 6 are respectively provided with a shovel contact surface 9, the shovel contact surface 9 corresponds to the inclined surface of the shovel chicken 10, the shovel chicken 10 is connected to the driving output end of the press, the T-shaped groove 7 in the middle of the side pushing plate 6 is inserted with the T-shaped head 8, the T-shaped head 8 is connected to the end surface of the horizontal part of the L-shaped rod 14, the vertical part of the L-shaped rod 14 is connected to the output end of the oil cylinder 12, the oil cylinder 12 is fixed on the rod body fixing plate, the cylinder body fixing plate 13 is fixed on the fixed end of the press, the cylinder body fixing plate 13 is respectively connected with the limiting sliding plate for guaranteeing the sliding of the side pushing plate 6, the limiting sliding plate is fixedly connected with the cylinder body fixing plate 13, the side pushing plate 6 is in sliding contact with the limiting sliding plate, and the sliding guide plate 16 is provided with three groups.
[0023] When the mold is closed, the lower mold plate 4 with lateral sliding hole is stationary, and the upper mold plate 5 moves. The output end of the oil cylinder 12 drives the L-shaped rod 14 and the T-shaped head 8 to move simultaneously while the upper mold plate 5 moves. Because there is a delay gap 17 between the T-shaped head 8 and the T-shaped groove 7, after the upper mold plate 5 moves down and the upper mold insert 1 contacts the lower mold insert 3 of the lower mold plate 4, the slider 2 has not yet contacted the lower mold insert 3 of the lower mold plate 4. At this time, the spade chicken 10 moves down and pushes the side push plate 6 to move. Because of the effect of the delay gap 17, the side push plate 6 drives the slider 2 to continue moving for the distance of the delay gap 17. At this time, the end of the slider 2 contacts the side surface of the upper mold insert 1 and the lower mold insert 3, and the mold closing is completed. After the injection is completed, the mold is demolded. When demolding, the spade chicken 10 moves up. At this time, the side push plate 6 is affected by the ejection spring 11, and at the same time, the side push plate 6 drives the slider 2 to move out of the distance of the delay gap 17. Then, the side push plate moves out of the slider 2 by pulling the L-shaped rod 14 of the oil cylinder 12, and at the same time, the upper mold plate 5 moves up under the driving of the press, thereby realizing demolding. Therefore, because of the delay gap 17 and the ejection spring 11, the resetting process of the slider 2 can be delayed during the mold closing process, and thus the upper mold insert 1 and the lower mold insert 3 can be protected.
