Description

Technical Field

[0001] The utility model relates to the technical field of post-processing equipment for injection molding products, in particular to a high-efficiency injection molding nozzle processing equipment. Background Art

[0002] Injection molded products, a crucial component of plastics in modern manufacturing, rely heavily on the use of injection molds. Through precise mold design and efficient injection molding processes, injection molds inject molten plastic material into the mold cavity. After cooling and solidification, the workpiece is formed. This method not only significantly reduces production costs but also enables the manufacture of plastic products with complex geometries, meeting market demand for diverse and personalized products. During the injection molding process, sprues remain between batches of molded parts. These are residual plastic residues that connect the molded part to the mold's runners.

[0003] Traditionally, removing nozzles and separating molded parts relies on manual labor, where workers use scissors or knives to cut and remove the nozzles. While this method is straightforward, it's inefficient. Advances in technology have led to the development of ultrasonic vibration nozzle removal technology. This technology uses the energy generated by ultrasonic vibrations to act on the connection between the nozzle and the molded part, achieving precise and rapid nozzle separation.

[0004] Ultrasonic vibration sprue removal is primarily suitable for brittle plastic materials such as ABS and PC, which are susceptible to fracture and separation under ultrasonic waves. However, for tougher, softer plastics like PVC, TPU, silicone, and rubber, the efficiency and effectiveness of ultrasonic energy transfer are significantly reduced, making it difficult to effectively remove sprues. For example, in splicing model toy parts, the sprue is connected in the middle by a sprue and is flanked by clinker-made injection molded parts. Utility Model Content

The bracket is connected to the base, and a slotted rotating rod is rotatably connected between the brackets. Multiple separation impellers are slidably connected to the slotted rotating rod. The first motor is installed on the bracket, and the output shaft of the first motor is connected to the slotted rotating rod.

[0008] Furthermore, the pitch adjustment mechanism includes a connecting plate, a connecting seat, a gear, a rack and a connecting rod.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example: A high-efficiency injection nozzle processing equipment, such as Figure 1-Figure 5 As shown, it includes a base 1, a collecting box 102, a placing table 2, a separating mechanism 3 and a distance adjusting mechanism 4. The collecting box 102 is slidably connected to the bottom of the base 1. A discharge port 101 is opened in the middle of the base 1, and both sides of the discharge port 101 are inclined toward the middle. The placing table 2 is connected to the base 1. An arc-shaped groove is provided in the middle of the placing table 2 for placing the sprue. The placing table 2 is located at the top of the discharge port 101. A separating mechanism 3 is provided on the base 1. The separating mechanism 3 is used to separate the injection molded part from the sprue. The base 1 is provided with a distance adjusting mechanism 4 for adjusting the separating mechanism 3.

[0023] like Figure 1 and Figure 2 As shown, the separation mechanism 3 includes a bracket 301, a first motor 302, a separation impeller 303 and a slotted rotating rod 304. The bracket 301 is connected to the base 1. The slotted rotating rod 304 is rotatably connected between the brackets 301. A plurality of separation impellers 303 are slidably connected to the slotted rotating rod 304. The first motor 302 is installed on the bracket 301. The output shaft of the first motor 302 is connected to the slotted rotating rod 304. The first motor 302 is a low-speed, high-torque motor.

[0024] like Figure 1 and Figure 3As shown, the pitch adjustment mechanism 4 includes a connecting plate 401, a connecting seat 402, a gear 403, a rack 404 and a connecting rod 405. The connecting seats 402 are connected on both sides of the separation impeller 303. The connecting seat 402 is slidably connected to the slotted rotating rod 304. The bottom of the connecting seat 402 is rotatably connected to the connecting plate 401. The connecting plates 401 are rotatably connected to each other, and the rack 404 is slidably connected to the base 1. The end of the rack 404 is connected to the connecting plate 401, and the connecting rod 405 is rotatably connected to the base 1. The bottom of the connecting rod 405 is connected to the gear 403, and the gear 403 is engaged with the rack 404.

[0025] The staff puts the injection molded part with the nozzle on the placement table 2, and aligns the nozzle with the groove in the middle of the placement table 2. The nozzle slides along the groove, and then turns on the first motor 302. The first motor 302 drives the slotted rotating rod 304 to rotate. The slotted rotating rod 304 cooperates with the separation impeller 303 through the groove, thereby driving the separation impeller 303 to rotate. At this time, the separation impeller 303 is aligned with the connection between the injection molded part and the nozzle, and cooperates with the side of the placement table 2 to shear the nozzle, thereby separating the injection molded part. The nozzle remains on the placement table 2. The separated injection molded part falls onto the base 1 and passes through the discharge port 10 1 falls into the collection frame below. In order to adapt to the different connection positions of the nozzles of different injection molding products, before cutting the nozzle, it is necessary to rotate the connecting rod 405, and the connecting rod 405 drives the gear 403 to rotate. When the gear 403 rotates, it engages with the rack 404, driving the rack 404 to slide in the base 1. While the rack 404 pulls the connecting plate 401 to move, the connecting plates 401 rotate with each other, and the connecting seat 402 moves with the connecting plate 401, thereby driving the separation impeller 303 to slide on the slotted rotating rod 304 to adjust the shearing position to meet the shearing needs of different injection molding products.

[0026] like Figure 1 As shown, the base 1 also includes a blowing bellows 5 , which are installed on both sides of the base 1 .

[0027] The sheared injection molded parts are blown toward the lower material port 101 by the air blown toward the center by the blowing bellows 5 to assist in the discharge.

[0028] like Figure 4 As shown, it also includes a dustproof strip 6. A dustproof strip 6 is provided on the base 1. Both ends of the middle dustproof strip 6 are connected to the connecting seat 402, and one end of the end dustproof strip 6 is connected to the base 1.

[0029] When the connecting seat 402 moves, the dustproof strip 6 blocks the opening on the base 1, thereby preventing dust from falling into the base 1 and preventing the injection molded parts from getting stuck on the base 1 and affecting the movement of the connecting seat 402.

[0030] like Figure 5As shown, it also includes a pop-up mechanism 7, which includes a second motor 701 and a flywheel 702. The second motor 701 is installed at the bottom of the placement table 2, and the flywheels 702 are rotatably connected on the upper and lower sides of the placement table 2. The area between the two flywheels 702 is provided with a gap in the placement table 2, and the two flywheels 702 are in contact with each other to ensure the pressure between the water outlet and the water outlet. The second motor 701 is connected to the flywheel 702 at the bottom, and the second motor 701 is a high-speed, low-torque motor.

[0031] When pushing the sprue, the front end of the sprue is inserted between the two flywheels 702 to fix the front end of the sprue. After the shearing of the injection molded part is completed, the second motor 701 is turned on. Driven by the second motor 701, the bottom flywheel 702 pushes the sprue backward. The two flywheels 702 squeeze the sprue and the high-speed rotating flywheel 702 throws the sprue out of the placement table 2.

[0032] like Figure 1 As shown, a protective cover 8 is also included. The base 1 and the placement table 2 are connected to the protective cover 8. The protective cover 8 is located above the separation mechanism 3, and the connecting rod 405 is rotatably connected to the protective cover 8.

[0033] The protective cover 8 can prevent workers or other objects from coming into contact with the separation impeller 303 , thereby protecting the workers from injury and the separation impeller 303 from damage.

[0034] The staff places the injection molded part on the placement table 2 through the sprue, and the sprue of the injection molded part is aligned with the groove in the middle of the placement table 2 and slides along it to position, and then starts the first motor 302, which drives the slotted rotating rod 304 to rotate, and then drives the multiple separation impellers 303 slidingly connected thereon to rotate. The separation impeller 303 is aligned with the connection between the injection molded part and the sprue, and by cooperating with the side of the placement table 2, the sprue is sheared to achieve the separation of the injection molded part. The separated injection molded part falls on the base 1, and falls into the collection box 102 below through the discharge port 101. The wind blown toward the middle by the blowing bellows 5 assists the injection molded part to fall into the collection box 102. In view of the different connection positions of the nozzles of different injection molding products, the connecting rod 405 can be rotated, and the gear 403 driven by the connecting rod 405 engages with the rack 404, so that the rack 404 slides in the base 1, and the connecting seat 402 is pulled through the connecting plate 401, thereby adjusting the position of the separation impeller 303 on the slotted rotating rod 304 to meet the shearing requirements of different injection molding products. During the movement of the connecting seat 402, the dustproof strip 6 blocks the opening of the base 1 to prevent dust from entering and the injection molding parts from getting stuck. Before shearing, the front end of the nozzle is fixed under the extrusion of the flywheel 702. After the shearing is completed, the two flywheels 702 squeeze and finally throw the nozzle out of the placement table 2 through high-speed rotation. During the whole process, the protective cover 8 protects the staff and the separation impeller 303 from injury and damage, ensuring the safe and efficient operation of the equipment.

Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
