Description

Technical Field

[0001] The invention relates to the technical field of injection molding finishing, in particular to a device for removing a nozzle of an injection molding. Background Art

[0002] Ultrasonic sprue cutting is a device used to remove sprues from injection molded parts. Its principle relies primarily on the high-frequency vibrations of ultrasound. An ultrasonic generator generates a high-frequency electrical signal, which is converted into mechanical vibrations by a transducer. These vibrations are transmitted to the tool head or cutter, causing it to vibrate at the ultrasonic frequency. When the cutter or tool head contacts the sprue of a plastic product, the vibration energy is used to cut or separate the sprue.

[0003] During use, existing ultrasonic nozzle removal equipment requires a person to place an injection molded part with a nozzle under the tool head. The tool head then moves downward to press the nozzle of the injection molded part, generating high-frequency vibrations to separate the injection molded part from the nozzle. The tool head then moves upward, and the person needs to remove the nozzle from the bottom of the tool head and then place other injection molded parts with nozzles under the tool head. During this ultrasonic nozzle removal operation, the loading and removal of nozzle waste by the person affects the efficiency of the tool head in removing the nozzle of the injection molded part, resulting in poor continuity in the operation of the ultrasonic nozzle removal equipment during the batch removal of injection molded part nozzles.

The limiting block 8 is used to prevent the clamping plates 1 6 and 2 7 from detaching from the mounting base 4. The two limiting blocks 8 are movably abutted against a spring 1 9 on the side away from each other, and the spring 1 9 is movably sleeved on the outside of the cylindrical rod 5.

[0025] A socket 10 is fixedly embedded on the clamping plate 6, and a tapered hole 11 is opened inside the socket 10. A pad 12 is fixedly installed on the clamping plate 2 7 just below the socket 10. The cross-sectional shape of the upper end face of the clamping plate 2 7 is tapered, which is used to prevent the injection molded parts from falling on the clamping plate 2 7. The limit block 8 fixedly connected to the clamping plate 1 6 is fixedly connected to a connecting plate 13 at the end away from the clamping plate 1 6. A support rod 14 is fixedly installed at the lower end of the connecting plate 13, and a ball 15 is movably embedded at the lower end of the support rod 14.

[0026] Driving component 1 includes a trapezoidal top block 16 movably embedded in the upper end of the base 1, and the cross-sectional shape of the trapezoidal top block 16 is a right-angled trapezoid. The connection between ball 15 and the hypotenuse of the trapezoidal top block 16 is rolling contact. A push rod 17 is fixedly embedded on the side of the trapezoidal top block 16 close to the side wall of the hollow cylindrical seat 40, and the push rod 17 passes through the base 1. The push rod 17 is used to push the trapezoidal top block 16, and a spring 2 18 is fixedly installed on the side of the trapezoidal top block 16 away from the push rod 17.

[0027] The lower end of the hollow cylindrical seat 40 is movably embedded with a plurality of equally distributed ball bearings 41. A gear ring 42 is fixedly sleeved on the outer side of the hollow cylindrical seat 40, and the gear ring 42 is located on the lower side of the clamping assembly.

A motor is fixedly installed at the center of the lower end of the gear 2 43, and the motor is fixedly connected to the base 1.

[0028] Working principle: When using the device, the operator first pushes the trapezoidal top block 16 through the push rod 17. During the movement, the trapezoidal top block 16 drives the support rod 14 and the clamping plate 1 6 to move upward through the bevel. At this time, the operator places the injection molded part with the sprue between the clamping plate 1 6 and the clamping plate 2 7, and makes the center of the sprue located at the upper end of the pad 12. Then the operator releases the push rod 17, and the trapezoidal top block 16 moves back and resets under the drive of the compression elastic force of the spring 2 18. The clamping plate 1 6 will move downward under the drive of the compression elastic force of the spring 1 9, and cooperate with the clamping plate 2 7 to clamp the sprue of the injection molded part. When the clamping plate 16 moves downward to clamp the injection nozzle of the injection molded part, the main water injection port of the injection molded part will be inserted into the socket 10. The tapered hole 11 in the socket 10 positions the water injection port of the injection molded part, which can effectively enhance the stability of the clamping assembly in clamping the injection nozzle of the injection molded part. After the clamping assembly clamps the sprue of the injection molded part, the motor drives the gear ring 42 and the hollow cylindrical seat 40 to rotate through gear 2 43. The hollow cylindrical seat 40 rotates and sequentially transfers the injection molded part with the sprue to the protective box 19. In the process of the ultrasonic tool head 3 moving down to drive the injection molded part out of the sprue, personnel can load materials at the loading station, that is, personnel can load materials while the ultrasonic tool head 3 is working, so that the ultrasonic tool head 3 has a strong continuity in removing the sprue of the injection molded part and a high efficiency in removing the sprue of the injection molded part.

[0029] Example 2: Please refer to Figure 5 , this embodiment further explains Example 1, driving component 2 is installed between driving component 1 and protective box 19, driving component 2 includes an arc-shaped support bar 30 fixedly installed on the upper end of the base 1, and both ends of the arc-shaped support bar 30 are provided with inclined portions 31, and the ball 15 rolls in contact with the arc-shaped support bar 30 through the inclined portion 31, and the arc-shaped support bar 30 is used to drive the clamping plate 6 to move upward, and a plurality of equally spaced blocks 32 are fixedly installed on the upper end of the inclined portion 31, and the side of the block 32 close to the protective box 19 is provided with an inclined portion 2 33, and the ball 15 rolls in contact with the block 32 through the inclined portion 2 33, and the side of the block 32 away from the protective box 19 is provided with a vertical portion 34.

[0030] In this embodiment, when the hollow cylindrical seat 40 drives the clamping assembly and the nozzle to move out of the protective box 19 and continues to rotate, the ball 15 at the lower end of the support rod 14 will roll along the inclined portion 31 to the upper end of the arc-shaped support bar 30. During this process, the clamping plate 6 moves upward, and the nozzle waste may directly break away from the socket 10 or be stuck in the tapered hole 11 in the socket 10. As the hollow cylindrical seat 40 drives the clamping assembly to continue moving, the ball 15 at the lower end of the support rod 14 will roll along the inclined portion 2 33 of the block 32 to the upper end of the block 32, and the clamping plate 6 will move further upward in this process. When the ball passes through the vertical portion 34 of the block 32 and disengages from the block 32, the clamping plate 6 will instantly move downward driven by the compression force of the spring 9, causing the ball 15 to hit the arc-shaped support bar 30, which is conducive to vibrating the sprue waste stuck in the socket 10 out of the socket 10.

[0031] Example 3: Please refer to Figure 7 、 Figure 8This embodiment further explains Example 1. The blocking assembly includes two symmetrically distributed baffles 21, and the two baffles 21 are movably fitted with the left and right side walls of the protective box 19 respectively. Two symmetrically distributed capped pins 22 are fixedly installed on the left and right sides of the protective box 19, and the baffle 21 is in sliding contact with the capped pin 22 through a limiting straight groove 1. The capped pin 22 is used to prevent the baffle 21 from separating from the protective box 19. A plurality of equidistantly distributed tooth blocks 23 are provided on one end of the baffle 21 away from the hollow cylindrical seat 40, and a gear 24 is installed on the side of the two baffles 21 away from the hollow cylindrical seat 40.

[0032] A connecting shaft 25 is fixedly installed between the two gears 1 24, and the connecting shaft 25 is rotatably connected to the protective box 19 through a positioning seat. A gear frame 26 is cooperated with the side of the gear 1 24 away from the baffle 21, and a bent connecting rod 27 is fixedly installed at the center of the gear frame 26. The upper end of the bent connecting rod 27 is fixedly connected to a ring 28, and the ring 28 is fixedly sleeved on the outer side of the lifting frame 2. The lifting frame 2 is rotatably connected to the hollow cylindrical seat 40 through a bearing. A capped pin 29 is fixedly installed on the side of the protective box 19 away from the hollow cylindrical seat 40, and the bent connecting rod 27 is in sliding contact with the capped pin 29 through a limiting straight groove 2.

[0033] In this embodiment: after the hollow cylindrical seat 40 drives the clamping assembly and the injection molded part into the protective box 19, the lifting frame 2 drives the ultrasonic tool head 3 and the bent connecting rod 27 to move downward, and the bent connecting rod 27 moves downward to drive the two gears 1 24 to rotate through the gear frame 26, so that the gear 1 24 rotates through multiple tooth blocks 23 to drive the baffle 21 to move upward. When the ultrasonic tool head 3 is against the socket 10, the baffle 21 moves up to the highest point to block the left and right sides of the protective box 19, which is beneficial for the ultrasonic tool head 3 to press against the socket 10 to make the injection molded part detach from the water outlet under high-frequency vibration, preventing the injection molded part from jumping out of the protective box 19. When the ultrasonic tool head 3 moves up and resets, the two baffles 21 will also move down and reset to prevent the baffle 21 from blocking the clamping assembly from entering or leaving the protective box 19.

A hemisphere 36 is fixedly installed on the upper end of the connecting plate 2 35.

An arc-shaped baffle 37 is fixedly installed on the side of the positioning rod 39 away from the arc-shaped support bar 30.

A plurality of grooves 38 distributed at equal distances are opened on the lower side of the arc-shaped baffle 37, and the hemisphere 36 is in sliding contact with the arc-shaped baffle 37 through the plurality of grooves 38.

[0036] In this embodiment: after the hollow cylindrical seat 40 drives the clamping assembly to move to the driving assembly 2, and the clamping plate 1 6 moves up, the hemispherical body 36 at the upper end of the connecting plate 2 35 will slide in contact with the arc-shaped baffle 37 through multiple grooves 38 during the rotation process, so that the clamping plate 2 7 will generate continuous vibration during the rotation process, thereby assisting the clamping plate 2 7 to vibrate and shake off the sprue waste of the injection molded part.
