Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-6, an adjustable bottom plug structure for a three-station injection-blow mold comprises a support plate 1, a triangular plate 13 is slidably connected to the top surface of the support plate 1, three side surfaces of the triangular plate 13 are fixedly connected with three core bars 14, the core bars 14 can drive a blow-molded plastic bottle to move, a lower mold 3 is fixedly connected to the top surface of the support plate 1 at one side of the triangular plate 13, an upper mold 2 is arranged on the top surface of the lower mold 3, three bottle grooves are formed in the three core bars 14 at the same side corresponding to the opposite surfaces of the upper mold 2 and the lower mold 3, the blow-molding of the plastic bottle can be performed in the bottle grooves after the upper mold 2 and the lower mold 3 are assembled, the six bottle grooves are respectively slidably connected with the three core bars 14 at the same side, three blocks 8 are respectively slidably connected to one side of the triangular plate 13, the blocks 8, the bottom of the plastic bottle is recessed, the side surfaces of the three blocks 8 are fixedly connected with fixing rods 6, two sides of each fixing rod 6 are slidably connected with fixing frames 4 fixedly connected with the side surfaces of the lower die 3, and the inner side surfaces of the fixing frames 4 are fixedly connected with springs 41 fixedly connected with the lower die 3;
the side sliding connection of 3 one sides of relative bed die of dead lever 6 has two L type pieces 5, L type piece 5 can support dead lever 6, make sprue 8 can stretch into the bottle inslot when annotating and blowing, go up 2 sides of mould and correspond two L type pieces 5 and seted up two spacing grooves 21, two spacing grooves 21 medial surfaces respectively with two L type 5 sliding connection of piece, spacing groove 21 can restrict L type 5's position, two 5 opposite face fixedly connected with connecting rods 51 of L type piece, connecting rod 51 side central point department of putting closes soon and is connected with the threaded rod 52 of being connected with last mould 2 rotation, the position of connecting rod 51 and L type piece 5 can be adjusted to rotatory threaded rod 52, thereby adjust the position of dead lever 6, change sprue 8 and stretch into the length of bottle inslot.
The bottom surface of the supporting plate 1 is fixedly connected with a base 11, a power mechanism is arranged in the base 11, and the power mechanism can drive the upper die 2 and the triangular plate 13 to move. The top surface of the supporting plate 1 is fixedly connected with an injection mold 12 on one side of a triangular plate 13, and the injection mold 12 can perform a first process of plastic bottle injection and blow molding. The length of the spring 41 in a natural state is smaller than the distance from the side surface of one side of the fixing rod 6 relative to the lower die 3 to the inner side surface of the fixing frame 4, when the upper die 2 is lifted, the fixing rod 6 is attached to the lower end of the L-shaped block 5 under the action of the spring 41, so that the fixing rod 6 is far away from the lower die 3 to move, and the blocking block 8 can move out of the bottle groove. The length of the limiting groove 21 is larger than that of the top end of the L-shaped block 5, so that the limiting groove 21 is prevented from blocking the L-shaped block 5, and the position of the L-shaped block 5 cannot be adjusted by rotating the threaded rod 52.
