Description

Technical Field

[0001] The utility model relates to the technical field of de-sprue equipment, in particular to a full-automatic de-sprue device applied to nasal washer accessories. Background Art

[0002] During the injection molding process, nasal rinser accessories typically retain sprue material after demolding, requiring subsequent processing to remove it to obtain a finished injection-molded part that meets the requirements. Traditional sprue removal methods rely primarily on manual labor, where operators use scissors, knives, or specialized tools to manually cut out the sprue. However, manual sprue removal is slow, the quality of the cutouts varies, and production efficiency is low, while also easily damaging the appearance of the nasal rinser. Utility Model Content

[0003] In order to overcome the shortcomings of the background technology, the technical solution adopted by the present invention is: a fully automatic de-gating device for nasal wash accessories, including a de-gating device and a robot. The robot transfers the injection molded parts from the injection molding machine to the de-gating device. The de-gating device includes a workbench, a material discharge seat, a cutting mechanism, a material picking mechanism and a lifting platform arranged on the workbench. The material discharge seat is provided with a station slot for placing plastic parts;

[0004] The cutting mechanism includes a three-axis pneumatic slide, a pneumatic scissors and a blade. The three-axis pneumatic slide is distributed on one side of the unloading seat, and the three-axis pneumatic slide drives the pneumatic scissors to move relative to the unloading seat. The output end of the pneumatic scissors is provided with a blade for cutting the gate.

[0005] The material picking mechanism includes a linear module, a lifting cylinder, a movable plate and a second negative pressure tube. The output end of the linear module is connected to the lifting cylinder, and the output end of the lifting cylinder is connected to the movable plate. The linear module drives the movable plate to move between the discharge seat and the lifting platform. The movable plate is provided with a second negative pressure tube for moving the material from the discharge seat to the lifting platform.

[0006] By adopting the above technical solution, the robot grabs the gate material of the plastic part, takes the plastic part out of the injection mold, and automatically cuts the gate material of the plastic part through the cutting mechanism. At this time, the robot places the gate material in one place for centralized recycling, and then moves to the injection mold to take out the next plastic part. The material picking mechanism moves the plastic part from the discharge seat to the lifting platform, and the finished product is moved to the front of the staff through the lifting platform for the next inspection / packaging process. This device realizes the fully automated process of injection molded part picking, gate cutting, finished product transfer and waste material transfer through the collaborative operation of the robot and the de-gating device, reducing manual intervention, ensuring the incision quality of plastic parts, and effectively improving production efficiency.

[0007] The utility model is further configured as follows: the three-axis pneumatic slide includes a moving seat, an X-axis slide cylinder, a Z-axis slide cylinder and a Y-axis slide cylinder; the workbench is connected to the X-axis slide cylinder; the moving end of the X-axis slide cylinder is connected to the moving seat; the moving seat is connected to the Z-axis slide cylinder; the moving end of the Z-axis slide cylinder is connected to the Y-axis slide cylinder; and the moving end of the Y-axis slide cylinder is connected to the pneumatic scissors.

[0008] By adopting the above technical solution, the three-axis linkage control of the pneumatic scissors is realized through the X-axis slide cylinder, the Z-axis slide cylinder and the Y-axis slide cylinder, so as to flexibly adjust the position relationship between the pneumatic scissors and the discharge base, so that the pneumatic scissors can accurately cut each gate, and have a wide range of applications.

[0009] The utility model is further configured as follows: the linear module includes a first fixed plate, and a motor, a synchronous belt, a screw rod, a nut pair and a first linear slide rail arranged on the first fixed plate. The screw rod is rotatably connected to the first fixed plate, and the motor controls the rotation of the screw rod through the synchronous belt. The screw rod is meshed with the nut pair, and the nut pair is slidably connected to the first fixed plate through the first linear slide rail, and the nut is fixedly connected to the lifting cylinder.

[0010] Furthermore, the movable plate is provided with an extension portion and a mounting portion, the movable end of the lifting cylinder is fixedly connected to the extension portion, the mounting portion is provided with a wire groove, and the second negative pressure tube is fixedly connected to the movable plate through the wire groove.

[0011] By adopting the above technical solution, the material-taking mechanism can quickly transfer the injection molded parts through screw transmission. The second negative pressure tube passes through the wire groove and is adjustably connected to the movable plate through a nut. The lateral position of the second negative pressure tube can be adjusted through the wire groove to compensate for the installation error between the movable plate and the discharge seat.

[0012] The utility model is further configured as follows: the lifting platform includes a second fixed plate, a second linear slide rail and a transmission cylinder arranged on the second fixed plate, a material box for receiving materials, and an adapter plate arranged at the bottom of the material box, the output end of the transmission cylinder is connected to the adapter plate, and the adapter plate is fixedly connected to the second linear slide rail, and the material box is slidably connected to the second fixed plate through the second linear slide rail.

[0013] By adopting the above technical solution, the material box moves up and down toward the movable plate through the transmission cylinder, reducing the height difference between the second negative pressure tube and the material box, and preventing the surface of the injection molded part from being damaged due to excessive height difference when it falls into the material box.

[0014] The present invention is further configured such that the material box is connected to the adapter plate via a hinge, the material box is tilted downward toward the workbench, and an opening slot is provided on a side of the material box facing away from the workbench.

[0015] With the above technical solution, the material box is naturally tilted toward the transfer plate through the hinge, which prevents the injection-molded parts from falling out of the material box during the downward movement. When the material box moves to a low position, the staff rotates the material box through the hinge and pours the injection-molded parts onto the inspection table without having to take them out one by one, thus simplifying the material retrieval method.

[0016] The utility model is further configured such that the manipulator is provided with a positioning plate, a pneumatic chuck, a first negative pressure tube and a spring; the positioning plate is connected to a pneumatic chuck for clamping the gate material, and a first negative pressure tube for adsorbing the injection molded parts; the first negative pressure tube is slidably connected to the positioning plate, and a spring is provided between the first negative pressure tube and the positioning plate.

[0017] By adopting the above technical solution, when the injection mold is demolded, the robot assists the injection molded part in demolding through the first negative pressure tube, and maintains the balance of the injection molded part through the first negative pressure tube, so that the injection molded part can be accurately placed on the work station slot, and the gate material after cutting the injection molded part is clamped by the pneumatic chuck, so that the robot can transfer the gate material and collect it centrally.

[0018] The utility model is further configured such that symmetrically distributed cutting mechanisms are provided on both sides of the material discharging seat.

[0019] By adopting the above technical solution, the injection molding structure and the cutting mechanism are symmetrically designed to realize a double-station layout, so that the gate cutting action can be performed simultaneously on both sides of the discharge seat, thereby improving production efficiency.
