The blade 9 can gradually approach the blow-molded product and can trim the inside of the outer side of the blow-molded product, thereby realizing gradual trimming of the blow-molded product from the outside to the inside. After the trimming of the current position is completed, the lifting plate 3 is driven to rise and fall by the first driving mechanism 4, so that the remaining part of the blow-molded product can be trimmed. The entire trimming process is automated, saving labor costs, and has better effects and higher efficiency than manual trimming.

[0023] The first driving mechanism 4 includes a top plate 401, the bottom of which is connected to the top of the base 1 via a plurality of evenly distributed support columns 402, two symmetrically distributed first guide slide rods 403 are slidably mounted on the top plate 401, one end of the first guide slide rod 403 is fixedly mounted on the top of the lifting plate 3, and the top of the lifting plate 3 is also connected to a telescopic cylinder 404 mounted on the top plate 401.

[0024] In this embodiment, after the telescopic cylinder 404 is started, the lifting plate 3 connected to its telescopic end can be driven to move up and down, and the lifting plate 3 cooperates with the sliding connection between the two symmetrically distributed first guide slide rods 403 and the top plate 401, so that the lifting plate 3 will be more stable during the lifting process.

[0025] The second driving mechanism 6 includes a servo motor 601 mounted on the top of the lifting plate 3 . The output shaft of the servo motor 601 is connected to a rotating rod 603 via a pulley belt 602 . The rotating rod 603 is rotatably connected to the lifting plate 3 , and one end of the rotating rod is fixedly connected to the rotating plate 5 .

[0026] In this embodiment, after the servo motor 601 is started, the rotation rod 603 can be driven to rotate together through the transmission of the pulley belt 602, and the rotation plate 5 fixedly connected to the rotation rod 603 keeps rotating synchronously.

[0028] In this embodiment, after the screw rod 705 is driven to rotate on the internal thread of the second connecting sleeve 703, the second guide slide rod 704 and the first connecting sleeve 702 can be slid together with the sliding connection between the second guide slide rod 704 and the first connecting sleeve 702, thereby driving the mounting plate 701 to move in the horizontal plane direction, and the mounting shell 8 fixedly connected to the mounting plate 701 maintains synchronous movement.

[0029] The screw rod 705 is fixedly mounted with a first bevel gear 706 , which is meshedly connected with a second bevel gear 707 . The second bevel gear 707 is coaxial with the rotating axis of the rotating plate 5 , and the outer side wall is fixedly connected to the lifting plate 3 via two symmetrically distributed connecting rods 708 .

[0030] In this embodiment, when the second driving mechanism 6 drives the rotating plate 5 to rotate, the screw rod 705 and the first bevel gear 706 fixed thereon rotate synchronously. When the first bevel gear 706 follows the rotation of the rotating plate 5, it will rotate on the rotating plate 5 at the same time through meshing with the second bevel gear 707, thereby driving the screw rod 705 to rotate on the rotating plate 5 to move the mounting plate 701 in the horizontal plane direction.

[0031] In the above embodiment, the second bevel gear 707 is fixedly connected to the lifting plate 3 through two symmetrically distributed connecting rods 708, so it will rise and fall together with the lifting plate 3, thereby ensuring that the first bevel gear 706 and the second bevel gear 707 are always meshed, and a transparent protective cover 10 is provided at the bottom of the second bevel gear 707, which can not only protect the waste chips generated by trimming, but also observe the trimming progress at any time through the transparent protective cover 10.

[0035] In this embodiment, after the columnar injection molded product is inserted into the circumferentially arranged positioning columns 205 through its opening, the electric push rod 201 is started. During the contraction process, the electric push rod 201 will pull the positioning columns 205 through the connecting rod 203, and then cooperate with the sliding connection of the slider 206 on the slide rail 207 to drive the circumferentially arranged positioning columns 205 to move outward, thereby abutting against the inner wall of the injection molded product to position it.

[0036] In the above embodiment, a plurality of evenly distributed rubber bumps 208 are provided on the outer side wall of the positioning column 205 to increase the friction with the inner wall of the injection molded product and improve the positioning effect.
