Description

Technical Field

[0001] This invention relates to the field of injection molding processing technology, and more specifically to an integrated device for vibration breaking and cutting of injection molding material strips. Background Technology

[0002] In injection molding, molten plastic flows through a channel formed by a gating system and a runner, injecting into multiple parallel product cavities. After molding and cooling, the plastic within these channels solidifies into strips or mesh-like waste material, known as sprue. This sprue is tightly connected to multiple products, forming a complete injection-molded part. To quickly separate the product from the waste material, vibration breaking or shearing breaking methods are typically chosen based on the product's characteristics. Referencing patent CN119305148A, this method essentially involves bending the injection-molded part using pressure rollers and disconnecting the connection between the injection-molded part and the sprue using multiple guide rods. This breaks the injection-molded part, avoiding potential omissions that might occur with ultrasonic vibration breaking. A cutter is also installed in the direction of sprue movement to sever the sprue, allowing it to be directly crushed for easier subsequent recycling, eliminating the need for primary crushing and saving space after crushing.

[0003] From the perspective of breaking injection molding strips, traditional equipment uses a single breaking method, generally processing the injection molding strip through separate high-frequency vibration or mechanical blade cutting. This results in a narrow applicability, as it cannot promptly change the processing method for injection molding parts of different materials. Therefore, it is necessary to combine integrated vibration breaking and vibration cutting to allow for switching between different processing methods according to different needs during operation. To this end, we provide an integrated equipment for vibration breaking and cutting of injection molding strips to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated device for vibration breaking and cutting of injection molded part strips, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: An integrated device for vibration breaking and cutting of injection molded part strips includes a base, the top surface of which is provided with a main unit to assist in the rapid collection of workpieces, and the interior of the main unit is provided with an operating unit that can vibrate and cut the workpieces simultaneously. The main unit includes a main body fixedly installed on the top surface of the base, an air outlet fixedly installed on the inner side of the main body for assisting material movement, and a material collection bin movably installed inside the other side of the main body for collecting materials. The working unit includes a support frame fixedly installed inside the main body of the machine, an integrated plate movably installed inside the top surface of the support frame, a fixed seat fixedly installed on the top surface of the integrated plate for clamping materials, and a vibrating knife assembly fixedly installed on the other end of the top surface of the clamping arm for cutting materials.

[0006] A further improvement of the technical solution of the present invention is that: an electromagnetic vibrator is fixedly connected to one end of the bottom surface of the integrated plate, a connecting seat is fixedly connected to the output end of the electromagnetic vibrator, a connecting arm is movably connected to the side of the connecting seat, a clamping arm is fixedly connected to the side of the connecting arm, and a plastic part is movably connected inside the clamping arm.

[0007] A further improvement of the technical solution of the present invention is that: a motor is fixedly connected inside the fixed base, two bevel gears are rotatably connected inside the fixed base, a slider is threadedly connected to the outer surface of the bevel gears, and one end of the bevel gears is movably connected to the output end of the motor.

[0008] A further improvement of the technical solution of the present invention is that: the slider is slidably connected to the inside of the side of the fixed seat, a limit rod is threadedly connected to the inside of the side of the slider, and a fixed rod is rotatably connected to the inside of the other side of the slider.

[0009] A further improvement of the technical solution of the present invention is that: the limiting rod is movably connected inside the fixed rod, a cutting clamp arm is fixedly connected to the side of the fixed rod, and a flexible pad is fixedly connected to the top side of the cutting clamp arm.

[0010] A further improvement of the technical solution of the present invention is that: a pneumatic vibrating cutter is fixedly connected to the top surface of the vibrating knife assembly, and a cutter head is fixedly connected to the output end of the pneumatic vibrating cutter.

[0011] A further improvement of the technical solution of the present invention is that: a guide slope is fixedly connected to one end of the inner bottom surface of the main body of the machine body, a screening frame is movably connected to the inside of the collection bin, and a protective plate is fixedly connected to the top surface of the main body of the machine body.

[0012] A further improvement of the technical solution of the present invention is that: an air inlet bracket is fixedly connected to the side of the air outlet, a fan is installed inside the air inlet bracket, and an air outlet filter is fixedly connected to the bottom of the side of the air outlet.

[0013] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows: 1. This invention provides an integrated device for vibration breaking and cutting of injection molded parts strips. Based on the characteristics of the injection molded parts, a relatively hard plastic part suitable for vibration breaking is placed on the side of the clamping arm. Driven by the connecting seat, the connecting arm and the clamping arm cooperate to clamp the injection molded part. At this time, the electromagnetic vibrator will drive the connecting seat to vibrate at high frequency. Through vibration, fatigue fracture is caused at the weak point inside the injection molded part, realizing efficient separation of the strip and the workpiece. 2. This invention provides an integrated device for vibration breaking and cutting of injection molded parts strips. By placing the workpiece, which is relatively soft and not suitable for vibration breaking, inside a flexible pad, the two bevel gear rods are driven by a motor to rotate, which further drives the slider and the cutting clamp arm to clamp the plastic part. After the workpiece is firmly fixed inside the flexible pad, pressure is applied to the workpiece. At this time, the part of the workpiece that needs to be cut comes into contact with the cutting head. The pneumatic vibration cutter drives the cutting head to vibrate at high frequency, so as to achieve rapid cutting of the target position of the plastic part. 3. This invention provides an integrated device for vibration breaking and cutting of injection molded part strips. When the working unit is in operation, the produced workpieces and strips are piled up inside the main body of the machine. At this time, the material will slide directly down the guide slope. At the same time, the air inlet bracket will drive the airflow through the fan. The airflow passes through the bottom of the working unit under the guidance of the air outlet. At this time, the piled material will move forward under the push of the airflow, ensuring that all the material can slide down the guide slope. Because the conveyor belt itself has multiple branches, when the conveyor belt and the material fall into the collection bin at the same time, some of the conveyor belt will be caught inside the screening frame. Since the gap inside the screening frame is large, the workpiece will directly pass through the screening frame and fall into the collection bin, reducing the difficulty of screening the conveyor belt and the workpiece later.

[0016] The present invention will be further described in detail below with reference to embodiments: Example 1: As Figure 1-6 As shown, the present invention provides an integrated device for vibration breaking and cutting of injection molded part strips, including a base 1, a main body unit 2 for assisting in the rapid collection of workpieces on the top surface of the base 1, and an operating unit 3 for vibrating and cutting the workpieces inside the main body unit 2. The operating unit 3 includes a support frame 31 fixedly installed inside the main body 21, an integrated plate 32 movably installed inside the top surface of the support frame 31, a fixed seat 34 for clamping materials fixedly installed on the top surface of the integrated plate 32, and a vibrating knife group 35 for cutting materials fixedly installed on the other end of the top surface of the clamping arm 33. The integrated plate 32 is movably connected to the top surface of the support frame 31 and can rotate about the connection axis with the support frame 31 to adjust the current angle of the integrated plate 32. The electromagnetic vibrator 36 can drive the entire connecting seat 37 to move left and right at a high frequency. The clamping arm 33 and the connecting arm 39 can clamp the plastic part 38 under the drive of the internal components of the connecting seat 37. An electromagnetic vibrator 36 is fixedly connected to one end of the bottom surface of the integrated board 32. A connecting seat 37 is fixedly connected to the output end of the electromagnetic vibrator 36. A connecting arm 39 is movably connected to the side of the connecting seat 37. A clamping arm 33 is fixedly connected to the side of the connecting arm 39. A plastic part 38 is movably connected inside the clamping arm 33.

[0017] In this embodiment, based on the characteristics of the injection molded part, a plastic part with a relatively hard material that is suitable for vibration-induced breakage is placed on the side of the clamping arm 33. Under the drive of the connecting seat 37, the connecting arm 39 and the clamping arm 33 cooperate to clamp the injection molded part. At this time, the electromagnetic vibrator 36 will drive the connecting seat 37 to vibrate at a high frequency. Through vibration, fatigue fracture is caused in the weak points inside the injection molded part, thereby achieving efficient separation of the material strip and the workpiece.

[0018] Example 2: Figure 1-6As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, a motor 311 is fixedly connected inside the fixed base 34, two bevel gear rods 312 are rotatably connected inside the fixed base 34, a slider 313 is threadedly connected to the outer surface of the bevel gear rods 312, one end of the bevel gear rods 312 is movably connected to the output end of the motor 311, the slider 313 is slidably connected to the inside of the side of the fixed base 34, a limit rod 310 is threadedly connected to the inside of the side of the slider 313, and a fixed rod 315 is rotatably connected to the inside of the other side of the slider 313; The output end of the motor 311 inside the fixed base 34 is provided with a drive bevel gear. The fixed base 34 is provided with two bevel gears 312, which are arranged opposite to each other inside the fixed base 34. The two bevel gears 312 respectively mesh with the drive bevel gears provided at the output end of the motor 311. The limiting rod 310 is movably connected inside the fixed rod 315. The side of the fixed rod 315 is fixedly connected to the cutting clamp arm 314. The top side of the cutting clamp arm 314 is fixedly connected to the flexible pad 316. The top surface of the vibrating knife assembly 35 is fixedly connected to the pneumatic vibrating cutter 318. The output end of the pneumatic vibrating cutter 318 is fixedly connected to the cutting head 317. The outer surface of slider 313 is slidably connected to the inner side of fixed base 34. One end of the side of slider 313 is internally threaded to the outer surface of bevel gear 312. There are two sliders 313, which are arranged opposite to each other inside the side of fixed base 34. Fixed rod 315 rotates inside slider 313, thereby adjusting the current angle of cutting clamp arm 314. Limiting rod 310 can pass through fixed rod 315 to fix it at the current angle to ensure stability during operation. There are four vibrating blade groups 35, which are evenly distributed on the top surface of the integrated plate 32. The position of the pneumatic vibrating cutter 318 on the top surface of the vibrating blade group 35 is adapted to the shape of the plastic part 38 and is distributed at the position where it needs to be cut.

[0019] In this embodiment, a workpiece made of a soft material, unsuitable for vibration and breakage, is placed inside a flexible pad 316. The motor 311 drives two bevel gears 312 to rotate, which in turn drives the slider 313 to cooperate with the cutting arm 314 to clamp the plastic part 38. After the workpiece is firmly fixed inside the flexible pad 316, pressure is applied to the workpiece. At this time, the part of the workpiece that needs to be cut comes into contact with the cutting head 317. The pneumatic vibration cutter 318 drives the cutting head 317 to vibrate at high frequency, thereby achieving rapid cutting of the target position of the plastic part 38.

[0020] Example 3: As Figure 1-6As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, the main body unit 2 includes a main body 21 fixedly installed on the top surface of the base 1, an air outlet 26 fixedly installed on the inner side of the main body 21 for assisting material movement, and a material collection bin 22 movably installed inside the other side of the main body 21 for collecting materials. A guide slope 24 is fixedly connected to one end of the inner bottom surface of the main body 21. A screening frame 23 is movably connected inside the material collection bin 22. A protective plate 25 is fixedly connected to the top surface of the main body 21. An air inlet bracket 27 is fixedly connected to the side of the air outlet 26. A fan 28 is installed inside the air inlet bracket 27. An air outlet filter 29 is fixedly connected to the bottom side of the air outlet 26. The working unit 3 is located inside the main body 21. The overall height of the main body 21 is higher than that of the working unit 3. The guide slope 24 is located on the bottom surface of the support frame 31. The bottom height of the guide slope 24 is about the same as the height of one end of the collection bin 22. The opening of the collection bin 22 is higher on one side and lower on the other side, which is conducive to the collection of workpieces. The screen frame 23 moves inside the collection bin 22 and can be quickly removed. The air inlet bracket 27 is equipped with two sets of fans 28. The input end of the air inlet bracket 27 is equipped with a dust filter. The air outlet 26 is equipped with an inclined surface inside, which can guide the airflow. The air outlet filter 29 can filter the airflow again.

[0021] In this embodiment, when the work unit 3 is working, the produced workpieces and material strips are piled up inside the main body 21. At this time, the material will slide directly down the guide slope 24. At the same time, the air inlet bracket 27 will drive the airflow through the fan 28. The airflow passes through the bottom of the work unit 3 under the guidance of the air outlet 26. At this time, the piled material will move forward under the push of the airflow, ensuring that all the material can slide down the guide slope 24. Since the material belt itself has multiple branches, when the material belt and the material fall into the collection bin 22 at the same time, some of the material belt will be caught inside the screening frame 23. Since the gap inside the screening frame 23 is large, the workpiece will directly pass through the screening frame 23 and fall into the collection bin 22, reducing the difficulty of screening the material belt and the workpiece in the later stage.

[0022] The working principle of this integrated equipment for vibration breaking and cutting of injection molded parts strips will be explained in detail below.

[0023] like Figure 1-6 As shown, based on the characteristics of the injection molded part, a plastic part with a relatively hard material that is suitable for vibration fracture is placed on the side of the clamping arm 33. Under the drive of the connecting seat 37, the connecting arm 39 and the clamping arm 33 cooperate to clamp the injection molded part. At this time, the electromagnetic vibrator 36 will drive the connecting seat 37 to vibrate at a high frequency. Through vibration, fatigue fracture is caused in the weak part inside the injection molded part, realizing efficient separation of the material strip and the workpiece. The workpiece, which is made of a soft material and is not suitable for vibration to break, is placed inside the flexible pad 316. The motor 311 drives the two bevel gears 312 to rotate, which in turn drives the slider 313 to cooperate with the cutting arm 314 to clamp the plastic part 38. After the workpiece is firmly fixed inside the flexible pad 316, pressure is applied to the workpiece. At this time, the part of the workpiece that needs to be cut comes into contact with the cutting head 317. The pneumatic vibration cutter 318 drives the cutting head 317 to vibrate at high frequency, so as to quickly cut the target position of the plastic part 38. When the work unit 3 is in operation, the produced workpieces and material strips are piled up inside the main body 21. At this time, the material will slide directly down the guide slope 24. At the same time, the air inlet bracket 27 will drive the airflow through the fan 28. The airflow passes through the bottom of the work unit 3 under the guidance of the air outlet 26. At this time, the piled material will move forward under the push of the airflow, ensuring that all the material can slide down the guide slope 24. Since the material belt itself has multiple branches, when the material belt and the material fall into the collection bin 22 at the same time, some of the material belt will be caught inside the screening frame 23. Since the gap inside the screening frame 23 is large, the workpiece will directly pass through the screening frame 23 and fall into the collection bin 22, reducing the difficulty of screening the material belt and the workpiece in the later stage.

[0024] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements made without departing from the spirit of the present invention are within the scope of protection of the present invention.
