Description
Technical Field
[0001] This utility model relates to the field of injection molding shearing technology, specifically a shearing device for injection molding heads. Background Technology
[0002] The shearing device for injection molding heads is a crucial piece of equipment in the plastic product processing stage. It is mainly used to precisely remove excess material from the product after injection molding in order to obtain a finished product that meets the size and quality requirements.
[0003] Currently, in existing technologies, it is difficult to ensure that the injection head is transported to the cutting position along a precise straight trajectory during the cutting process. This results in a large deviation in the position of the injection head reaching the cutting area each time, which cannot meet the requirements of high-precision cutting and easily causes quality problems such as uneven cutting surface and non-standard dimensions. In view of this, we propose a cutting device for injection heads. Utility Model Content
[0004] The main objective of this invention is to provide a cutting device for injection molding heads, which can solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model proposes a shearing device for an injection molding head, comprising a shearing table, an injection molding head body disposed on the outer wall of the shearing table, a wire saw assembly disposed on the shearing table, a grinding wheel disposed on the outer side of the wire saw assembly, a conveyor table fixedly connected to the shearing table, a stabilizing transmission device disposed on the outer side of the conveyor table, and a limit device disposed on the stabilizing transmission device, the stabilizing transmission device comprising:
[0006] The outer wall of the shearing table is provided with a sliding groove, and a sliding seat is slidably connected in the sliding groove. A motor is provided on the sliding seat, and the output shaft of the motor is fixedly connected to a roller.
[0007] A connecting rod is fixedly connected to roller one, and the connecting rod is slidably connected to the lower surface of the conveyor table. The connecting rod is also fixedly connected to roller two.
[0008] Preferably, the limiting device includes an inclined groove, the outer side of the conveyor table is provided with an inclined groove, and a collar is rotatably connected to the connecting rod. During the linear movement of the connecting rod, the collar moves linearly accordingly.
[0009] Preferably, a fixing rod is fixedly connected to the outer wall of the collar, and the fixing rod is elastically connected to the limiting rod by a spring.
[0010] Preferably, the limiting rod is fixedly connected to the protrusion, the protrusion is slidably connected in the inclined groove, the protrusion on the collar slides in the inclined groove, and as the inclined groove drives the protrusion to rise, the limiting rod is stretched and raised by the spring, which facilitates timely adjustment of the height position of the protrusion.
[0011] Preferably, a pressing rod is fixedly connected to the outer wall of the protrusion, and a limiting plate is provided above the pressing rod. The inclined groove drives the protrusion to rise, which in turn drives the pressing rod to rise and gradually contact the limiting plate.
[0012] Preferably, the limiting plate is fixedly connected to a connecting shell, which is elastically connected to a fixed shaft via a spring. The fixed shaft is fixedly connected to the conveyor table. When the extrusion rod contacts the corner of the limiting plate, it pushes the limiting plate to move towards the conveyor table. The rotation of the two sets of limiting plates on the conveyor table allows the injection head body to be aligned and positioned, ensuring that the injection head body is in a precise position to be cut when entering the shearing area. This lays the foundation for high-precision shearing operations of the wire saw assembly. After the work is completed, the extrusion rod is retracted by the stable transmission device, and the limiting plate releases its elastic potential energy through the spring, thereby achieving the reset function.
[0013] This invention provides a shearing device for injection molding heads. It has the following advantages:
[0014] (1) The shearing device of the injection molding head is powered by a stable transmission device and a motor. The output shaft of the motor drives roller one to rotate, and the rotation of roller one is transmitted to roller two through a connecting rod, causing roller two to rotate synchronously. Rollers one and two move in a stable linear motion along the sliding groove. The injection molding head body placed on the conveyor table is limited and transmitted along with the movement of rollers one and two, and is finally sent to the working area of the shearing device for shearing operation. This achieves high-precision linear motion of the conveyor table, allowing the injection molding head body to be accurately transported to the shearing position, avoiding bumps and collisions during the conveying process, and reducing the risk of scratches and damage to the product surface. At the same time, the motor drive provides stable power, making the conveying speed uniform and improving the transmission efficiency.
[0015] (2) The shearing device of the injection head, through the setting of the limiting device, the clever cooperation of the inclined groove and the protrusion, and the elastic buffer of the spring, can accurately control the position of the limiting rod and the extrusion rod regardless of the movement stage of the conveyor table, so as to ensure that the injection head is limited at the appropriate time, which greatly improves the accuracy of the injection head alignment and positioning. The two sets of limiting plates align and limit the injection head under the action of the extrusion rod, effectively eliminating the position deviation such as offset and skew that may occur during the conveying process, so that the injection head enters the shearing area of the wire saw assembly with a precise posture.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figures 1-8 This utility model proposes a shearing device for injection molding heads, including a shearing table 1, an injection molding head body 2 disposed on the outer wall of the shearing table 1, and a wire saw assembly 3 disposed on the shearing table 1. When the injection molding head body 2 is positioned, the wire saw assembly 3 begins to operate. A control component drives a wire wheel to rotate, causing a taut metal wire to reciprocate at high speed. During this movement, the metal wire contacts the injection molding head body 2. Due to the high-speed movement and tension of the metal wire, it generates a cutting force on the injection molding head body 2, gradually cutting and separating the material head. During the cutting process, the control part of the wire saw assembly 3 adjusts the speed and cutting force of the wire saw in real time according to factors such as the material and thickness of the injection head body 2. A grinding wheel 4 is set on the outside of the wire saw assembly 3. In order to obtain a smoother shearing surface or meet specific processing requirements, after the wire saw assembly 3 finishes cutting, the grinding wheel 4 will grind and dress the shearing surface. The grinding wheel 4 rotates at high speed under the driving force, and its rough surface contacts the shearing surface of the injection head body 2. The burrs and uneven parts on the surface of the material head are removed through the grinding action, making the shearing surface smoother and flatter. The shearing table 1 is fixedly connected to the conveyor table 5. A stable transmission device 6 is set on the outside of the conveyor table 5. A limit device 7 is set on the stable transmission device 6. The stable transmission device 6 includes a sliding groove 61.
[0030] In this embodiment of the invention, in order to accurately deliver the material to the shearing position and improve transmission efficiency, specifically, a sliding groove 61 is provided on the outer wall of the shearing table 1. A sliding seat 62 is slidably connected in the sliding groove 61, and a motor 63 is mounted on the sliding seat 62. The output shaft of the motor 63 is fixedly connected to roller 64. When the motor 63 is started, the output shaft of the motor 63 drives roller 64 to rotate. Roller 64 is fixedly connected to a connecting rod 65, which is slidably connected to the lower surface of the conveying table 5. The connecting rod 65 is fixedly connected to roller 67. The rotation of roller 64 is transmitted through the connecting rod 67. Rod 65 transmits power to roller 67, causing roller 67 to rotate synchronously. Roller 64 and roller 67 move stably in a straight line along sliding groove 61. The injection head body 2, placed on conveyor table 5, is limited and transported along with the movement of roller 64 and roller 67, and is finally sent to the working area of the shearing device for shearing operation. This achieves high-precision linear motion of conveyor table 5, ensuring that the injection head body 2 is accurately transported to the shearing position, avoiding bumps and collisions during the conveying process, and reducing the risk of scratches and damage to the product surface. At the same time, motor 63 provides stable power, making the conveying speed uniform and improving the transmission efficiency.
[0031] Furthermore, to achieve precise dynamic limiting and improve shearing accuracy, the limiting device 7 specifically includes an inclined groove 71. An inclined groove 71 is formed on the outer side of the conveyor table 5. A collar 72 is rotatably connected to the connecting rod 65. During the linear movement of the connecting rod 65, the collar 72 moves linearly accordingly. A fixing rod 73 is fixedly connected to the outer wall of the collar 72. The fixing rod 73 is elastically connected to the limiting rod 75 via a spring 74. The limiting rod 75 is fixedly connected to a protrusion 76, which is slidably connected in the inclined groove 71. The protrusion 76 on the collar 72 slides... In the inclined groove 71, as the inclined groove 71 drives the protrusion 76 to rise, the limiting rod 75 is stretched and raised by the spring 74, which facilitates timely adjustment of the height position of the protrusion 76. A pressing rod 77 is fixedly connected to the outer wall of the protrusion 76, and a limiting plate 78 is provided above the pressing rod 77. The inclined groove 71 drives the protrusion 76 to rise, and simultaneously drives the pressing rod 77 to rise and gradually contact the limiting plate 78. A connecting shell 79 is fixedly connected to the limiting plate 78. The connecting shell 79 is elastically connected to the fixed shaft 711 through a spring 710. The fixed shaft 711 is fixedly connected to... Connected to the conveyor table 5, the extrusion rod 77 contacts the corner of the limiting plate 78, pushing the limiting plate 78 to move towards the conveyor table 5. The rotation of the two sets of limiting plates 78 on the conveyor table 5 causes the injection head body 2 to be aligned and limited, ensuring that the injection head body 2 is in a precise position to be cut when entering the shearing area, laying the foundation for the high-precision shearing operation of the wire saw assembly 3. After the work is completed, the extrusion rod 77 is driven to retract through the stable transmission device 6, and the limiting plate 78 releases its elastic potential energy through the spring 710 to achieve the reset function, through the inclined groove 71 and the protrusion. The ingenious combination of 76 and the elastic buffer of spring 74 ensures that the position of the limiting rod 75 and the extrusion rod 77 can be precisely controlled regardless of the movement stage of the conveyor table 5. This ensures that the injection head is limited at the appropriate time, greatly improving the accuracy of the injection head alignment and positioning. The two sets of limiting plates 78, under the action of the extrusion rod 77, align and limit the injection head, effectively eliminating the possible positional deviations such as offset and skew during the conveying process, so that the injection head enters the shearing area of the wire saw assembly 3 with a precise posture.
[0032] In this invention, during use, motor 63 is started. The output shaft of motor 63 drives roller 64 to rotate. The rotation of roller 64 is transmitted to roller 67 through connecting rod 65, causing roller 67 to rotate synchronously. Roller 64 and roller 67 move stably in a straight line along sliding groove 61. The injection head body 2 placed on conveyor table 5 is limited and transported along with the movement of roller 64 and roller 67, and is finally sent to the working area of the shearing device for shearing operation. This achieves high-precision linear motion of conveyor table 5, enabling the injection head body 2 to be accurately transported to the shearing position, avoiding bumps and collisions during the conveying process, and reducing the risk of scratches and damage to the product surface. Meanwhile, the motor 63 provides stable power, ensuring uniform conveying speed and improving transmission efficiency. During the linear movement of the connecting rod 65, the collar 72 moves linearly accordingly. The protrusion 76 on the collar 72 slides in the inclined groove 71. As the inclined groove 71 drives the protrusion 76 to rise, the limiting rod 75 is stretched and raised by the spring 74, facilitating timely adjustment of the height position of the protrusion 76. The inclined groove 71 drives the protrusion 76 to rise, simultaneously driving the extrusion rod 77 to rise and gradually contact the limiting plate 78. The extrusion rod 77 contacts the limiting plate 78. At the corner of plate 78, the limiting plate 78 is pushed to move towards the conveyor table 5. The rotation of the two sets of limiting plates 78 on the conveyor table 5 makes the injection head body 2 aligned and positioned, ensuring that the injection head body 2 is in a precise position to be cut when entering the shearing area, laying the foundation for the high-precision shearing operation of the wire saw assembly 3. After the work is completed, the extrusion rod 77 is driven to retract through the stable transmission device 6, and the limiting plate 78 releases elastic potential energy through the spring 710 to achieve the reset function. After the injection head body 2 is positioned, the wire saw assembly 3 starts to work. The control component drives the wire wheel to rotate, making the taut metal wire reciprocate at high speed. During the movement, the metal wire contacts the injection head body 2. Due to the high speed movement and certain tension of the metal wire, it will generate a cutting force on the injection head body 2, gradually cutting and separating the material head. The grinding wheel 4 rotates at high speed under the driving force. Its rough surface contacts the shearing surface of the injection head body 2, and removes the burrs and uneven parts on the surface of the material head through the grinding action, making the shearing surface smoother and flatter.
