Mounting part 34, one end of the cutter 35 is connected to the connecting part 33, the mounting part 34 is provided with a third mounting hole 341, the third mounting hole 341 extends along the front and rear direction of the cutter slide 30, the cutter mounting bracket 31 is provided with a third connecting hole (not shown) corresponding to the third mounting hole 341, the cutter slide 30 is slidably connected to the longitudinal slide rail 15, the punching cylinder 37 is located below the base 10, the cutter 35 has an arc-shaped blade 36, the sprue punching position 11 is provided with a sprue discharge port 101, and a first hopper 16 is provided below the sprue discharge port 101. In this embodiment, the cylinder driving method can also be replaced by a motor driving a lead screw driving method.

[0052] The left and right sides of the product unloading position 12 are provided with product unloading components 50 for removing the product 57 from the movable platform 13. The product unloading component 50 includes a scraper 51 and a scraping cylinder 52 for controlling the left and right movement of the scraper 51. A product unloading port 102 is provided below the scraper 51. A guide plate 53 for guiding the product 57 to the product unloading port 102 is provided between the scraper 51 and the product unloading port 102. A guide strip 551 is provided at the front end of the scraper 51. The guide strip 551 extends outward at an angle from the front end of the scraper 51 and is integrally formed with the scraper 51. The two ends of the guide plate 53 are installed on the base 10 through the support plate 54. A U-shaped baffle 55 is also provided above the product discharge port 102. The U-shaped baffle 55, the support plate 54 and the guide plate 53 form an upward-facing flared mouth 56. The flared mouth 56 is connected to the product discharge port 102. A second hopper 17 connected to the product discharge port 102 is provided below the base 10.

[0053] The base 10 is also provided with a clamping assembly 40 for clamping the water inlet 58, a lifting cylinder 43 for controlling the up and down movement of the clamping assembly 40, and a left and right moving cylinder 44 for controlling the left and right movement of the lifting cylinder 43. The left and right moving cylinder is a slide cylinder. The clamping assembly 40 includes a clamp 41 and a clamping cylinder 42 for controlling the opening and closing of the clamp 41. The movable joint of the lifting cylinder 43 is connected to the clamping cylinder 42. The lifting cylinder 43 is mounted on the left and right moving cylinder 44. The left and right moving cylinder 44 is mounted on the positioning slide 21.

[0054] It should be noted that the distance from the lower end of the scraper 51 to the base 10 is less than the distance from the upper end of the product 57 to the base 10, so that when the scraper cylinder 52 drives the scraper 51 to retract, the product 57 can be moved off the movable platform 13.

[0055] It should also be noted that the water inlet 58 in this invention includes a main channel water inlet 59 and a branch channel water inlet 60. The clamp 41 is used to clamp the main channel water inlet 59, and the cutter 35 is used to cut off the branch channel water inlet 60.

[0056] The working principle of this invention is as follows: The initial position of the movable platform 13 is located at the sprue punching position 11. The robotic arm (not shown) picks up the injection-molded product 57 onto the movable platform 13. The positioning cylinder 28 pushes the positioning slide 21 and drives the positioning column 26 to move, so that the positioning column 26 is inserted into the product 57 for positioning. The pressure ring 27 presses against the product 57. At the same time, the left and right moving cylinder 44 drives the lifting cylinder 43 to move towards the movable platform 13. The clamp 41 clamps the main channel sprue 59. The punching cylinder 37 controls the cutting slide 3. The 0-speed cylinder drives the cutter 35 to move, and the cutter 35 cuts off the sprue 60 of the diversion channel, so that the sprue 60 of the diversion channel is disconnected from the product 57. The lifting cylinder 43 controls the clamping cylinder 42 to rise, and the sprue 58 moves up away from the movable platform 13. The driving cylinder 18 controls the movable platform 13 to move to the product unloading position 12. The scraping cylinder 52 controls the scraper 51 to move the product 57 off the movable platform 13, so that the product 57 flows out from the product unloading port 102. At the same time, the clamp 41 is released, and the sprue 58 falls and flows out from the sprue unloading port 101.

[0057] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the actual technology of the present invention shall still fall within the scope of the technical solution of the present invention.
