[0021] Please refer to Figures 2-12 The utility model provides the following technical scheme: a slider delay structure for the case that product 1 exists three direction reverse buckling, the structure includes slider one 2, delay slider two 3, delay slider three 4, inclined guide pillar one 5, inclined guide pillar two 6 and inclined guide pillar three 7, inclined guide pillar one 5, inclined guide pillar two 6 and inclined guide pillar three 7 can be designed according to the number of mould needs, the embodiment sets up inclined guide pillar one 5, inclined guide pillar two 6 and inclined guide pillar three 7 as 2, the inside of slider one 2, delay slider two 3 and delay slider three 4 is connected with the middle and both sides of product 1 respectively, is connected at the reverse buckling of product 1 three directions, inclined guide pillar one 5, inclined guide pillar two 6 and inclined guide pillar three 7 are respectively inclined and penetrate in the back side of slider one 2, delay slider two 3 and delay slider three 4, inclined guide pillar one 5, inclined guide pillar two 6 and inclined guide pillar three 7 are respectively fixed on the front mould and vertically move in slider one 2, delay slider two 3 and delay slider three 4 respectively, delay structure is set up on delay slider two 3 and delay slider three 4, and the delay structure includes delay surface one 31, inclined hole two 32, delay surface two 41 and inclined hole three 42, when opening the mould, inclined guide pillar one 5 vertically moves up and drives slider one 2 to move back, at this time because delay structure is set up on delay slider two 3 and delay slider three 4, inclined guide pillar two 6 and inclined guide pillar three 7 vertically move up at the beginning but cannot provide the power of moving back to delay slider two 3 and delay slider three 4 respectively, so delay slider two 3 and delay slider three 4 are stationary, after continuing to open the mould, inclined guide pillar one 5, inclined guide pillar two 6 and inclined guide pillar three 7 vertically move up and drive slider one 2, delay slider two 3 and delay slider three 4 to move back respectively, so that slider one 2, delay slider two 3 and delay slider three 4 complete demoulding synchronously, thereby exit three direction reverse buckling on product 1, because the mechanical structure of delay slider two 3, delay slider three 4, inclined guide pillar two 6 and inclined guide pillar three 7 is adopted to control the sequence of opening the mould, also makes the phenomenon of backtracking not appear in opening the mould, product 1 surface quality is high, the structure is stable, does not stick to the mould, and the space occupation is small, the cost of mould and the cost of later maintenance are reduced.

[0022] Specifically, the vertical delay surface one 31 is arranged in the middle of the outer side of the delay slider two 3, and the vertical delay surface two 41 is arranged in the middle of the outer side of the delay slider three 4. When the mold is opened at the beginning, the front mold moves upward gradually, and the delay surface one 31 and the delay surface two 41 are in contact with the front mold, which can prevent the delay slider two 3 and the delay slider three 4 from retreating backward. The inclined hole two 32 and the inclined hole three 42 are arranged at the rear of the delay slider two 3 and the delay slider three 4, respectively. The inclined hole two 32 and the inclined hole three 42 are inclined to the front side, and the radial dimensions of the inclined hole two 32 and the inclined hole three 42 are larger than those of the inclined guide pillar two 6 and the inclined guide pillar three 7, respectively. At the beginning, the inclined guide pillar two 6 and the inclined guide pillar three 7 are installed at the front end in the inclined hole two 32 and the inclined hole three 42. When the mold is opened at the beginning, the rear end of the inclined hole two 32 and the inclined hole three 42 is avoided, and the inclined guide pillar two 6 and the inclined guide pillar three 7 gradually approach the rear end of the inclined hole two 32 and the inclined hole three 42 when they are initially moved upward. During this process, the inclined guide pillar two 6 and the inclined guide pillar three 7 cannot provide power for the delay slider two 3 and the delay slider three 4 to move backward. In addition, during this process, the front mold is also in contact with the delay surface one 31 and the delay surface two 41, which resists the backward movement of the delay slider two 3 and the delay slider three 4, so that the delay slider two 3 and the delay slider three 4 delay the backward movement.

[0023] Specifically, the inclined hole one 21 is arranged at the rear of the slider one 2 and inclined to the front side. The radial dimension of the inclined hole one 21 is matched with that of the inclined guide pillar one 5, and the inclined guide pillar one 5 is inserted into the inclined hole one 21. When the mold is opened at the beginning, the inclined guide pillar one 5 is moved upward to push the slider one 2 to move backward.

When the mould opens, oblique guide pillar one 5, oblique guide pillar two 6 and oblique guide pillar three 7 move upwards along with the front mould, slider one 2 is driven to move backwards by oblique guide pillar one 5, at the beginning, because the oblique hole two 32 and oblique hole three 42 rear end on delay slider two 3 and delay slider three 4 are empty, oblique guide pillar two 6 and oblique guide pillar three 7 gradually approach the oblique hole two 32 and oblique hole three 42 rear end when moving upwards at the beginning, in this process, oblique guide pillar two 6 and oblique guide pillar three 7 cannot provide the power of backward movement for delay slider two 3 and delay slider three 4, in addition, in this process, the front mould moves upwards, but always contacts with delay surface one 31 and delay surface two 41, and resists the backward movement of delay slider two 3 and delay slider three 4, so that delay slider two 3 and delay slider three 4 delay and retreat, in this process, slider one 2 moves backwards first, and the distance is d, d is 5.4mm, and the mould has opened 35mm at this time, continue to open the mould, the front mould continues to move upwards, and the front mould is separated from delay surface one 31 and delay surface two 41, and slider one 2, delay slider two 3 and delay slider three 4 are driven to move backwards by oblique guide pillar one 5, oblique guide pillar two 6 and oblique guide pillar three 7 respectively, and the demoulding is completed synchronously, so that the three direction reverse buckling in product 1 is exited.

[0025] When product 1 has reverse buckling on three sides, the utility model can solve the mould slider opening sequence, reduce the mould space, reduce the production cycle, facilitate maintenance and other problems, avoid the cost of mould production and manufacturing, and avoid the expensive cost of mould later rectification.
