[0002] In injection molding, in order to make full use of the mold and improve production efficiency, for the injection molding of small parts, multiple mold cavities are usually set in one mold, so that multiple small parts can be injection molded in one mold, and the connecting part between the small parts is the injection gate. After injection molding, the injection gate needs to be cut and removed to form an independent injection molded part. At present, the methods for removing the injection gate mainly include manual cutting of the injection gate, which is easy to miss cutting and labor-intensive; or, holding the injection molded part close to the ultrasonic machine, and the ultrasonic wave emitted by the ultrasonic machine breaks the injection gate, so that the injection gate is automatically cut off. The handheld injection molded part cannot guarantee the precise distance from the ultrasonic machine. When the distance between the injection molded part and the ultrasonic machine is too close, the injection molded part is easy to be damaged by vibration. When the distance between the injection molded part and the ultrasonic machine is too close, it is not easy to break the injection gate. In the process of removing the injection gate, both of the above two methods require manual assistance, with high labor costs and low reliability. Summary of the invention

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0030] In injection molding, for smaller parts, in order to make full use of the mold, multiple mold cavities are usually set in one mold, so that multiple parts can be formed in the same mold, and the connection between the parts is the injection gate. The injection gate is generally thinner and finer, which is convenient for breaking and separating the injection gate and the part. The ultrasonic device for removing the injection gate breaks the connection between the injection gate and the part through ultrasonic vibration, so as to realize automatic breaking and removal of the injection gate.

[0031] In one of the embodiments, please also refer to Figures 1 to 3 , an ultrasonic device for removing an injection molding gate comprises a fixed mold 1, a movable mold 2, an ultrasonic machine 3 and a horizontal driving mechanism 4. The movable mold 2 and the fixed mold 1 enclose a cavity adapted to the injection molded part 010. The injection molded part 010 comprises a plurality of injection molded parts and injection molding gates connecting the various parts. During the operation of the ultrasonic device, the fixed mold 1 remains stationary, and the movable mold 2 can approach or move away from the movable mold 2 under the drive of the horizontal driving mechanism 4. After the injection molded part 010 is moved to the fixed mold 1 using a manipulator or other mechanism that can move the injection molded part 010, the injection molded part 010 is clamped in the clamping structure provided on the fixed mold 1, and the horizontal driving mechanism 4 drives the movable mold 2 to move toward the fixed mold 1, so that the movable mold 2 and the fixed mold 1 are molded together, and the injection molded part 010 is fixed inside the cavity. The ultrasonic machine 3 emits ultrasonic waves to make the fixed mold 1 and the movable mold 2 ultrasonically vibrate, thereby vibrating and breaking the injection molded part 010 in the cavity. After a predetermined period of vibration, the movable mold 2 is translated away from the fixed mold 1 by the horizontal driving mechanism 4, and the injection molded parts automatically fall into the silo 9 under the action of gravity. Among them, the clamping structure is set corresponding to the structure of the injection molded part 010. More specifically, the clamping structure is used to clamp the injection molding gate, and the injection molded part is not fixed by the clamping structure, and the injection molded part and the injection molding gate can be separated under ultrasonic vibration; or, the clamping structure is used to clamp the injection molded part, so that the injection molding gate is not fixed by the clamping structure, and the injection molded part and the injection molding gate can also be separated under ultrasonic vibration. When it is necessary to remove the injection molding gate of the injection molded part 010 with a different structure, it is only necessary to replace the fixed mold 1 and the movable mold 2 with the fixed mold 1 and the movable mold 2 corresponding to the corresponding injection molded part 010.

[0032] Compared with the prior art, the ultrasonic device for removing the injection molding gate provided by the present invention comprises a fixed mold 1, a movable mold 2, an ultrasonic machine 3 and a horizontal driving mechanism 4. After the injection molded part 010 is placed in the fixed mold 1, the horizontal driving mechanism 4 drives the movable mold 2 to move toward the fixed mold 1 to close the mold so that the injection molded part 010 is fixed in the mold cavity. After the ultrasonic machine 3 vibrates the fixed mold 1 and the movable mold 2, the gate of the injection molded part 010 therein is broken. The horizontal driving mechanism 4 drives the movable mold 2 away from the fixed mold 1, and the broken injection molded part 010 can automatically fall. The combination of the fixed mold 1 and the movable mold 2 makes the ultrasonic vibration of the injection molded part 010 more sufficient, avoids the situation that the injection molding gate is not broken by vibration, improves the reliability of gate removal, and does not require manual shearing or holding the injection molded part 010, reduces the workload of the production line workers, and reduces the labor cost.

[0033] In one embodiment, when the injection molded part 010 is fixed in the fixed mold 1, the above-mentioned clamping structure is clamped on the injection gate, so that the injection molded part is not fixed by the clamping structure, and the injection molded part and the injection gate can be separated under ultrasonic vibration, and the injection molded part falls into the silo 9 under the action of gravity, and the injection gate still remains in the fixed mold 1. The injection gate remaining on the fixed mold 1 is removed by a robot, or the fixed mold 1 includes a first fixed mold unit and a second fixed mold unit, and the first fixed mold unit and the second fixed mold unit clamp the injection gate, and when the above two are separated, the injection gate falls into the plastic recovery bin.

[0034] In another embodiment, the ultrasonic device for removing the injection molding gate also includes a manipulator for installing the injection molding part 010. A through hole 10 running longitudinally through the fixed mold 1 is provided, and the manipulator can load the injection molding part 010 from the through end of the through hole 10. At this time, the manipulator is located on the side of the fixed mold 1 facing away from the movable mold 2, so that the movable mold 2 can move toward the fixed mold 1 to close the mold while the manipulator clamps the injection molding part 010. After closing the mold, the injection molding part 010 is fixed in the mold cavity, and the manipulator releases the injection molding part 010. In this case, after the ultrasonic vibration is completed, the movable mold 2 and the fixed mold 1 are separated, and the injection molding gate and the injection molding part fall under the action of gravity, and there is no need to use the manipulator again to remove the injection molding gate or the injection molding part.

[0035] Furthermore, since the movable mold 2 moves horizontally under the action of the horizontal driving mechanism 4, the fixed mold 1, the injection molded part 010, and the movable mold 2 are arranged in sequence along the horizontal direction. Compared with the solution in which the fixed mold, the injection molded part, and the movable mold are arranged along the vertical direction, the injection molded parts and the injection gate can automatically fall under the action of gravity, and no additional mechanism is required to remove the injection molded part 010 from the cavity. In addition, the function of the manipulator only needs to meet the requirements of horizontal movement and vertical movement to place the injection molded part 010 into the cavity. If the fixed mold, the injection molded part, and the movable mold are arranged along the vertical direction, the manipulator also needs to meet the rotation function, and the injection molded part 010 can be rotated to a horizontal state before the injection molded part 010 can be placed into the cavity.

[0036] In one of the embodiments, the distance between the ultrasonic machine 3 and the fixed mold 1 is fixed, and the head 32 of the ultrasonic machine 3 is arranged facing the outside of the fixed mold 1 or the outside of the movable mold 2. When the ultrasonic machine 3 is started, the ultrasonic vibration of the head 32 can realize the function of vibrating and breaking the injection molded parts and the injection gates.

[0037] In another embodiment, see Figure 2 The ultrasonic device for removing the injection gate also includes an ultrasonic machine driving mechanism, which can adjust the position of the ultrasonic machine 3 relative to the fixed mold 1 and the movable mold 2, so as to facilitate the adjustment of the position of the ultrasonic machine 3 according to the connection strength of the injection gate, and also facilitate the operation of the manipulator, and reserve operating space for the manipulator. The function of the ultrasonic machine driving mechanism is to move the ultrasonic machine 3 so that the ultrasonic machine 3 is directed toward or away from the movable mold 2 and the fixed mold 1. More specifically, the ultrasonic machine 3 includes a body 31 and a head 32. Optionally, the head 32 is arranged on the side of the movable mold 2 facing away from the fixed mold 1, that is, the fixed mold 1, the injection molded part 010, the movable mold 2, and the head 32 are arranged in sequence. The head 32 can approach or move away from the movable mold 2 under the action of the ultrasonic machine driving mechanism, and the head 32 emits ultrasonic waves, so that the movable mold 2 and the fixed mold 1 vibrate together, and the injection molded part 010 also fully vibrates, so that the injection gate and the injection molded part are completely broken. Of course, the head 32 can also be arranged on the side of the fixed mold 1 facing away from the movable mold 2, that is, the head 32, the fixed mold 1, the injection molded part 010, and the movable mold 2 are arranged in sequence, and the head 32 can be close to or far away from the fixed mold 1.

[0038] In one embodiment, see Figure 1 and Figure 2 The movable mold 2 and the ultrasonic machine 3 are both connected to the horizontal output end of the horizontal driving mechanism 4, and the horizontal driving mechanism 4 can drive the movable mold 2 and the ultrasonic machine 3 to move at the same time. In this way, the distance between the movable mold 2 and the ultrasonic machine 3 is fixed. When the movable mold 2 is molded with the fixed mold 1, the distance between the head 32 of the ultrasonic machine 3 and the fixed mold 1 is within the working distance range. After the mold is closed, the ultrasonic machine 3 can be started to vibrate and break the injection gate.

[0039] Please refer to one of the examples Figure 2 , the horizontal driving mechanism 4 includes a horizontal driving member, a lead screw 41 driven to rotate by the horizontal driving member, and a slider 42 arranged on the lead screw 41, and the ultrasonic machine 3 and the movable mold 2 are fixedly connected to the slider 42. In this embodiment, the horizontal driving mechanism 4 is arranged at the bottom of the ultrasonic machine 3, and can drive the ultrasonic machine 3 to move as a whole. The horizontal driving member can be selected as a stepping motor, a servo motor, etc. The horizontal driving member drives the lead screw 41 to rotate, so that the slider 42 on the lead screw 41 moves horizontally, thereby driving the ultrasonic machine 3 and the movable mold 2 to move horizontally. Optionally, the slider 42 is fixedly connected to the bottom of the ultrasonic machine 3.

[0040] In one embodiment, see Figure 1 and Figure 2The ultrasonic device for removing the injection gate also includes a machine table 5, and the horizontal drive mechanism 4 and the fixed mold 1 are fixed to the machine table 5. A protective shell 8 is also fixed to the machine table 5, and the movable mold 2 and the fixed mold 1 are both arranged in the protective shell 8. The head 32 of the ultrasonic machine 3 is also arranged in the protective shell 8. The function of the protective shell 8 is to protect the fixed mold 1, the movable mold 2 and the head 32, so that the ultrasonic vibration is carried out in the protective shell 8 and isolated from the external environment. More specifically, the horizontal drive member of the horizontal drive mechanism 4 is fixed to the machine table 5, and the machine table 5 has a supporting effect on the lead screw 41, and supports the lead screw 41 above the machine table 5.

[0041] In one embodiment, see 1 and Figure 3 The protective shell 8 includes at least one openable and closable door panel 81, and the fixed mold 1 is fixed to the inner wall of the door panel 81. When the door panel 81 is opened, the structure inside the protective shell 8 can be observed, which is convenient for timely maintenance and replacement of parts. When the fixed mold 1 is fixed to the inner wall of the door panel 81, the fixed mold 1 can be opened along with the door panel 81, so it is convenient to check whether there are any injection molding gates or injection molding parts remaining in the fixed mold 1. If there are injection molding gates or injection molding parts remaining in the fixed mold 1, the residues can also be removed manually. More specifically, the protective shell 8 includes three door panels 81, which are respectively located on three sides of the protective shell 8. The door panel 81 to which the fixed mold 1 is fixed is arranged opposite to the ultrasonic machine 3. The door panel 81 is not arranged on the side of the protective shell 8 close to the ultrasonic machine 3, so as to provide an avoidance position for the ultrasonic machine 3.

[0042] In one embodiment, see Figure 3 The ultrasonic device for removing the injection gate also includes a silo 9 for collecting the injection molded parts 010 after vibration, and the silo 9 is arranged below the mold joint of the fixed mold 1 and the movable mold 2. When the movable mold 2 is away from the fixed mold 1, the injection molded parts in the cavity fall into the silo 9, and the injection molded parts are automatically collected, making full use of gravity, without the need for a robot or manual removal of the injection molded parts. The shape of the silo 9 is not limited here, and is preferably funnel-shaped.

[0043] In one embodiment, see Figure 2 , the ultrasonic device for removing the injection gate also includes a base 7 and a height adjustment mechanism 6 for adjusting the height of the ultrasonic machine 3. The ultrasonic machine 3, the height adjustment mechanism 6, and the base 7 are arranged in sequence from top to bottom. When the structure of the injection molded part 010 that requires ultrasonic vibration changes, the fixed mold 1 and the movable mold 2 are correspondingly replaced with structures that are compatible with the injection molded part 010. In this way, the center of the movable mold 2 and the fixed mold 1 may change. In order to ensure the ultrasonic vibration effect, the head 32 of the ultrasonic machine 3 needs to be on the same axis as the center of the movable mold 2 and the fixed mold 1. The height adjustment mechanism 6 of the ultrasonic machine 3 can adjust the height of the head 32. At this time, the height of the fixed mold 1 and the movable mold 2 remains unchanged, so that it is directly opposite to the center of the movable mold 2 and the fixed mold 1 to enhance the adaptability of the ultrasonic device.

[0044] Optionally, casters 72 and foot supports 71 are provided at the bottom of the base 7, and the provision of the casters 72 facilitates the movement of the entire ultrasonic device, and when the ultrasonic device is moved to a corresponding position, the foot supports 71 can be rotated so that the foot supports 71 contact the ground to fix the ultrasonic device. The foot supports 71 are threadedly connected to the base 7.

[0045] In one embodiment, see Figure 2 The height adjustment mechanism 6 includes a threaded rod 61 threadedly connected to the base 7 and a hand wheel 62 for rotating the threaded rod 61. The threaded rod 61 is vertically arranged, and the upper end of the threaded rod 61 is connected to the ultrasonic machine 3, and the lower end of the threaded rod 61 is connected to the hand wheel 62. The hand wheel 62 drives the threaded rod 61 to rotate, the base 7 remains stationary, and the threaded rod 61 moves the ultrasonic machine 3 up or down. The rotation angle of the hand wheel 62 is selected according to specific needs. More specifically, a rotation scale is provided on the hand wheel 62, which is convenient for the operator to control the distance of the ultrasonic machine 3 to move up or down.

[0046] In another embodiment, the ultrasonic machine 3, the horizontal driving mechanism 4, the protective shell 8, etc. are all arranged above the machine platform 5, and the height adjustment mechanism 6 is arranged below the machine platform 5. The upper end of the threaded rod 61 is fixedly connected to the machine platform 5. The rotation of the threaded rod 61 can move the entire machine platform 5 up or down, and the heights of the head 32, the movable mold 2, and the fixed mold 1 of the ultrasonic machine 3 are changed accordingly, so that the ultrasonic device can be matched with other workstations and the applicability of the ultrasonic device is improved.

[0047] In one embodiment, see Figure 2 and Figure 4 The height adjustment mechanism 6 also includes a support rod 63 for supporting the ultrasonic machine 3 and a locking member 64 for locking the support rod 63 and the base 7. The support rod 63 and the threaded rod 61 are parallel to each other, and the upper end of the support rod 63 is connected to the ultrasonic machine 3, and the lower end of the support rod 63 is slidably connected to the base 7. When the threaded rod 61 rotates, the ultrasonic machine 3 moves up or down accordingly, and the upper end of the support rod 63 also moves up or down accordingly, and the lower end of the support rod 63 slides relative to the base 7. After sliding to the corresponding position, the locking member 64 can lock the support rod 63 and the base 7, thereby locking the position of the ultrasonic machine 3 and preventing the ultrasonic machine 3 from moving down under the action of gravity. The number of support rods 63 can be multiple to strengthen the support of the ultrasonic machine 3. Preferably, the number of support rods 63 is four, which are respectively arranged at the four corners of the ultrasonic machine 3.

[0048] Optionally, the locking member 64 includes an open ring 65 and a threaded member 68. The support rod 63 is inserted into the open ring 65. The threaded member 68 is disposed through the opening of the open ring 65. The open ring 65 can be clamped to the support rod 63 by rotating the threaded member 68 forward, and the open ring 65 can be loosened from the support rod 63 by rotating the threaded member 68 backward. The structure of the locking member 64 is not limited to the above structure.

[0049] In another embodiment, the upper end of the support rod 63 is fixedly connected to the machine platform 5, and the ultrasonic machine 3, the horizontal drive mechanism 4, the protective shell 8, etc. are all fixed on the upper part of the machine platform 5. More specifically, the upper end of the support rod 63 is sleeved with a flange 66, the flange 66 has a longitudinally arranged notch, and the fastener 67 horizontally penetrates the adjacent two sides of the notch, so that the fastener 67 can compress the above-mentioned notch, thereby locking the flange 66 on the support rod 63. The end of the flange 66 facing away from the support rod 63 is fixedly connected to the bottom of the machine platform 5. Preferably, the number of support rods 63 is four, which are respectively arranged at the four corners of the machine platform 5.
