Detailed Description
The multi-directional demolding mechanism of the injection mold is described in detail below with reference to the accompanying drawings.
As shown in fig. 1, 2 and 3, a multi-directional demolding mechanism of an injection mold comprises a sliding block 1, wherein a first loose core 2 and a second loose core 3 are movably connected to one side of the sliding block 1; the first loose core 2 is positioned below the second loose core 3; an inclined guide post 4 is arranged above the sliding block 1; a first molding surface 2.1 is arranged on one side of the first loose core 2; one side of the second loose core 3 is provided with a second molding surface 3.1; an inclined hole 1.1 is formed in the sliding block 1, and the inclined hole 1.1 is matched with the inclined guide post 4; the upper end of the inclined guide post 4 is connected with the upper die of the die; a first guide rail 1.2 and a second guide rail 1.3 are arranged on one side of the sliding block 1, and the first guide rail 1.2 is positioned above the second guide rail 1.3; two sides of the first loose core 2 are provided with first convex strips 2.2, and the first convex strips 2.2 are matched with the first guide rails 1.2; two sides of the second loose core 3 are provided with second convex strips 3.2, and the second convex strips 3.2 are matched with the second guide rails 1.3; two sides of the first loose core 2 are provided with first press blocks 2.3; the first pressing block 2.3 is connected with the lower die of the die; two sides of the second loose core 3 are provided with second pressing blocks 3.3; the second pressing block 3.3 is connected with the lower die of the die; third pressing blocks 1.4 are arranged on two sides of the sliding block 1; the third pressing block 1.4 is connected with the lower die of the die.
In practical use, the upper end of the inclined guide post 4 is connected with the upper die of the die, so that when the upper die moves upwards, the inclined guide post 4 can be driven to move upwards; the first pressing block 2.3, the second pressing block 3.3 and the third pressing block 1.4 are connected with the lower die of the die and are fixed, so that when the sliding block 1, the first core pulling 2 and the second core pulling 3 move, the first pressing block 2.3, the second pressing block 3.3 and the third pressing block 1.4 cannot move along with the sliding block, and meanwhile, the moving direction of the sliding block can be limited; part of the molding surface of the product is respectively contacted with the first molding surface 2.1 and the second molding surface 3.1, and other parts are limited by the mold core and fixed, so that the product cannot move along with the movement of the sliding block 1, the first core pulling 2 and the second core pulling 3.
