(2) the upper die continuously drives the substrate 1 to move upwards for a stroke n, the substrate 1 applies an upward acting force to the driving seat 312, and meanwhile, under the guiding action of the delay guide seat 311, the driving seats 312 on the first jacking die sinking assembly 3 and the second jacking die sinking assembly 4 respectively drive the jacking slide carriage 32 to move along the direction far away from the product 10, namely, the jacking slide carriages 32 on the first jacking die sinking assembly 3 and the second jacking die sinking assembly 4 are far away from the product 10 and are separated from each other;
(3) the product 10 is gripped away by the robot.
Specifically, in the step (1), in the process that the substrate 1 drives the driving seat 312 to move up synchronously with the jacking slide seat 32, no interaction force occurs between the driving seat 312 and the delay guide seat 311 due to the existence of the delay gap 313 between the two; after the synchronous upward movement by the stroke m, the delay gap 313 between the driving seat 312 and the delay guide seat 311 disappears.
The specific value of the stroke m can be set according to specific requirements, in practical application, the stroke m corresponds to the size of the delay gap 313, that is, after the driving seat 312 moves up by the stroke m, the outer guide inclined surface 31211 just contacts with the inner guide inclined surface 3111, that is, the delay gap 313 disappears. Specifically, the stroke m may be set to 20 mm, 30 mm, or the like.
Specifically, in the step (2), since the delay gap 313 between the driving seat 312 and the delay guide seat 311 has disappeared, the driving seat 312 drives the outer guide inclined surface 31211 on the inner wall of the driving seat 312 to move upwards along the inner guide inclined surface 3111 on the outer wall of the delay guide seat 311 under the pushing of the substrate 1, so that the driving seats 312 on the first and second jacking mold opening assemblies 3 and 4 respectively drive the jacking slide seat 32 to move in the direction away from the product 10.
The specific value of the stroke n can be set according to specific requirements, and in practical application, after the stroke n is completed, the distance between the two jacking slide bases 32 on the first jacking and die sinking assembly 3 and the second jacking and die sinking assembly 4 can enable the manipulator to extend into the clamped product 10. Specifically, the stroke n may be set to 20 mm, 30 mm, or the like.
By setting two sections of upward moving strokes, in the first section of upward moving stroke, the jacking sliding seat moves upwards to apply upward acting force on the product, the product is jacked up, the product and the mold core are loosened, and the purpose of quickly and accurately ejecting the product is achieved. In the second section of upward moving stroke, under the guiding action of the delay guide seat, the driving seat drives the jacking sliding seat to move along the direction away from the product, namely, the jacking sliding seat is away from the product and is separated from the product, namely, the purpose of quickly and accurately opening the die is realized. Therefore, the continuous and orderly proceeding of the product ejection step and the mold opening step is realized, and the rapid processing and forming of the product are facilitated.
