Injection molding technology is a commonly used plastic processing method that uses an injection machine to inject molten plastic into a mold and form the desired product shape after cooling. Gate black material is a kind of waste generated during the injection molding process, mainly from the gate part. The gate is a channel connecting the injection molding machine nozzle and the mold cavity, which is used to inject molten plastic into the mold cavity. During the injection molding process, some plastic will remain in the gate part. This part of the plastic often presents a black or dark appearance after molding, so it is called gate black material.

[0047] In this embodiment, an observation box is fixedly connected to the side of the machine body 1 above the loading and unloading assembly, and a switch door is movably connected to the outer side of the observation box. The observation box is convenient for the staff to check the loading and unloading situation, and the switch door is convenient for the staff to take out the cut injection molded parts.

[0048] The working principle of the present invention is: when in use, first, two mobile phone screen injection molded parts to be sheared are placed on the conveying rollers 5 of the two loading and unloading assemblies respectively, and during the placing process, the gate of the injection molded part is facing the chamber 2. Subsequently, the conveying roller 5 operates to convey the injection molded part forward until the injection molded part is blocked by the first baffle 14, and then the transverse linear motor 10 operates to move along the transverse linear guide 9. During the process, the limiting shaft 7 and the limiting slide 8 are relatively displaced, and the fourth cylinder 11 operates to extend the output shaft to make the strip plate 12 descend, and the second baffle 13 on the strip plate 12 follows the descent, and as the second baffle 13 moves toward the first baffle 14, the injection molded part is pushed to the middle position by the second baffle 13 to complete the centering alignment. It should be noted that the position of the horizontal plate 6 on the first baffle 14 can be adjusted according to the size of the injection molded part to be sheared, and the adjustment is completed by the corresponding transverse linear motor 10 and the transverse linear guide 9.

[0049] After the injection molded part is centered, the driving motor 18 of the push-pull mechanism drives the active wheel 19 to rotate. The active wheel 19 and the driven wheel 20 are connected by a belt 26, so the driven wheel 20 also rotates. During the process, the transmission block 21 on the belt 26 moves along and drives the push-pull plate 22 to move toward the notch 15. The transverse linear bearing and the transverse optical axis 25 are relatively displaced, and the L-shaped plate 23 on the push-pull plate 22 is adsorbed and connected to the injection molded part through the negative pressure suction head 24. As the push-pull plate 22 moves, the L-shaped plate 23 pushes the injection molded part in a direction perpendicular to the forward direction of the conveying roller 5 until the injection molded part passes through the notch 15 and the guide groove 34 and enters the chamber 2.

[0050] After the injection molded part enters the chamber 2, the first thing that contacts the injection molded part is the support plate 41 of the shearing assembly. The injection molded part is supported by the support plate 41 and continues to be pushed forward by the push-pull plate 22 until the injection molded part hits the T-block 54 of the clamping mechanism. Next, the third cylinder 53 of the clamping mechanism runs and extends the output shaft, driving the diaphragm 57 to rise, and the clamping block 56, which is rotatably connected to the diaphragm 57, undergoes relative displacement and rotates around the ear plate 55, so that the clamping block 56 is pressed down toward one end of the injection molded part to complete the clamping. It should be noted that the overall height of the clamping mechanism can be adaptively adjusted according to the different thicknesses of the injection molded parts of the mobile phone screen. The specific adjustment process is that the first cylinder 37 runs to drive the connecting rod 38 to rise and fall, and then drives the support plate 36 to rise and fall, and the clamping mechanism on the support plate 36 also follows the rise and fall.

[0051] After the injection molded part is clamped, the second cylinder 48 of the shearing mechanism runs to extend the output shaft, so that the connecting block 49 moves forward. During the process, the connecting block 49 drives the connecting plate 50 to move in the moving groove 47 through the connecting arm 51, and the connecting plate 50 drives the vertical plate 46 to move. The cutter head 52 on the vertical plate 46 moves and shears the black material at the gate of the injection molded part. Subsequently, the blower mechanism starts operating, and an external high-pressure air source enters the air storage chamber 28 through the air inlet 27 to store energy. The stored energy airflow is delivered to the vertical blower head 32 and the oblique blower head 33 through a hose. The vertical blower head 32 and the oblique blower head 33 blow out airflow downward to clean the injection molded parts and the shearing components. During the process, the vertical linear motor 30 moves slowly downward along the vertical linear guide rail 29, and the vertical blower head 32 and the oblique blower head 33 on the strip lifting plate 31 also move downward with it, which can not only improve the intensity of the airflow sprayed on the surface of the injection molded parts and the shearing components, but also can change the height of the oblique blower head 33 to perform multi-directional cleaning of debris contaminated on the shearing components.

[0052] After the injection molded part and the shearing assembly are cleaned, the third cylinder 53 of the clamping mechanism runs in the reverse direction to release the injection molded part, and the driving motor 18 of the push-pull mechanism also runs in the reverse direction, and cooperates with the adsorption force of the negative pressure suction head 24 to pull the injection molded part from the chamber 2 back to the conveying roller 5. The staff can take out the injection molded part by opening and closing the door. The present application can assist the staff to quickly complete the shearing of the black material at the gate of the injection molded part by setting the loading and unloading assembly and the shearing assembly. The overall degree of automation is high, and the efficiency of shearing the black material at the gate of the injection molded part can be effectively improved. In addition, the loading and unloading assembly and the shearing assembly can perform the shearing work on both sides synchronously, and the shearing speed can be accelerated without affecting the shearing effect. In addition, the shearing mechanism of the shearing assembly completes the work on both sides through one power source, which effectively saves energy.

[0053] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.

[0054] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
