[0002] In the field of injection molding machine technology, the precise and efficient drive of the injection platform is a key factor in ensuring product quality and production efficiency. With the continuous development of technology, technicians in this field are committed to optimizing the drive mode. Taking China Patent Publication No. CNCN7885308A as an example, the patent proposes an innovative injection control device, injection molding machine injection system and injection molding machine design, which transforms the traditional oil pump to drive the injection extrusion into a method where the injection control device directly drives the injection extrusion. This transformation does not increase the energy consumption of the system, but maintains or reduces the working power of the crude oil pump motor unit, so that it can operate at the same power consumption without increasing the processing cost. However, although this technical solution shows significant advantages in energy utilization and cost control, it also reveals the challenges that still need to be faced in the current injection molding machine technology field: the traditional drive mode still limits the overall performance improvement space of the injection molding machine to a certain extent due to its inherent defects such as large space occupation and low transmission efficiency. Summary of the invention

[0007] A driving member and a linkage extrusion member, wherein the driving member is arranged on the lead screw, and the driving member is respectively provided with a coupling hole I connected to the lead screw and a coupling hole II connected to the linkage extrusion member; a sliding assembly for limiting position and a magnet assembly for detecting displacement are arranged on the outer side of the driving member;

[0008] The rotation of the conical tooth II drives the driving member on the lead screw to move horizontally, and the linkage extrusion member arranged parallel to one side of the lead screw moves back and forth synchronously with the driving member.

[0009] The technical solution converts the rotary motion into horizontal motion through the mutually meshing conical teeth I and conical teeth II; through the driving member and the linkage extrusion member, the linkage extrusion member is arranged on one side of the lead screw to improve the space utilization rate of the device; through the sliding assembly and the magnet assembly, the accuracy of the movement of the linkage extrusion member is improved. Among them, the rotating shaft transmits the power of the injection electric cylinder to the conical teeth I, and the conical teeth I transmit the rotary motion to the conical teeth II meshed with it; the conical teeth are used to achieve the smooth transmission of the rotary motion and reduce the energy loss caused by friction and wear. The conical teeth II receive the rotary power from the conical teeth I and convert it into the rotary motion of the lead screw, and the lead screw converts the rotary motion into horizontal motion. By connecting with the coupling hole I of the driving member, the driving member moves horizontally along the axis of the lead screw; the driving member is a transitional member connecting the lead screw and the linkage extrusion member, which is used to transmit the horizontal motion of the lead screw to the linkage extrusion member; the setting structure of the driving member enables the extrusion member to be arranged parallel to one side of the lead screw when contracting, thereby improving the space utilization rate of the device; the linkage extrusion member is connected to the driving member through the coupling hole II to achieve synchronous reciprocating motion with the driving member. The sliding assembly is arranged on the outside of the driving part, which plays the role of limiting and guiding, ensuring that the driving part moves accurately on the screw and preventing it from deviating from the predetermined track or shaking; the magnet assembly is used to detect the displacement of the driving part, and through the interaction with the magnet assembly, the position information of the driving part is obtained in real time, thereby realizing precise control of the movement of the extruded part.

[0010] In some embodiments, the driving member is in a rectangular parallelepiped configuration, and the coupling hole I and the coupling hole II respectively penetrate the front and rear sides of the driving member;

The magnet seat is the carrier of the magnet assembly. The magnet seat is set on the top of the driving member and moves linearly with the driving member synchronously, so that the magnet moves with the movement of the driving member, thereby reflecting the displacement of the extrusion member mechanism in real time. The magnet interacts with the external sensor to generate an electrical signal for detecting the position information of the driving member, which is more accurate and reliable.

[0014] Another aspect of the present application provides an electric drive device for a shooting platform of an injection molding machine, comprising the following components:

[0015] The shell and the main control board, the shell is a hollow shell, and the electric drive extrusion of the injection molding machine shooting platform is wrapped inside the shell; the shell is respectively provided with a guide sleeve connected to the rotating shaft, a wiring port connected to the main control board, and a mounting hole connected to the magnet assembly; the main control board is located at a position corresponding to the wiring port inside the shell;

[0016] The shooting and shifting electric cylinder and the detection plate Ⅰ, the shooting and shifting electric cylinder is provided with a rotating shaft, and the rotating shaft is connected to the conical gear Ⅰ through a guide sleeve; the detection plate Ⅰ is located at the end of the conical gear Ⅰ and detects the rotation speed information of the shooting and shifting electric cylinder;

[0017] Detection plate II and cover plate, detection plate II is arranged in the mounting hole, detection plate II cooperates with the magnet assembly and detects the position information of the driving member; the cover plate is arranged on the outside of detection plate II and fixed to the housing;

[0018] Among them, the main control board includes a controller, which is respectively connected to the shooting electric cylinder, detection board I and detection board II; the controller receives the preset position information and current position information of the driving part and compares the two, and controls the rotation of the shooting electric cylinder according to the comparison result until the driving part reaches the preset position.

[0019] This technical solution realizes precise control of the driving part through the shell and main control board, shooting and moving electric cylinder, detection board I, detection board II and cover plate, which are functionally related and mutually supported. The shell, as a protective shell and integrated platform, provides a stable installation environment for the main control board, shooting and moving electric cylinder and other components; the main control board realizes precise control of the shooting and moving electric cylinder through the controller; the shooting and moving electric cylinder drives the movement of the electric extrusion part as a power source; the detection board I and the detection board II are responsible for monitoring the speed of the shooting and moving electric cylinder and the position information of the driving part respectively, providing data support for precise control. Among them, the shell is provided with a guide sleeve, a wiring port and a mounting hole to meet the needs of the device in terms of guidance, connection and control; the main control board is located at the corresponding position of the wiring port, which is convenient for connection and data exchange with the shooting and moving electric cylinder, detection board I and detection board II; the detection board I ensures the movement speed of the device by real-time monitoring of the speed of the shooting and moving electric cylinder, and provides data support for subsequent precise control; the detection board II accurately obtains the displacement data of the driving part through the interaction with the magnet assembly, providing an important basis for the precise control of the controller. The cover plate not only protects the detection plate II, but also makes the structure of the entire device more compact.

[0020] In some embodiments, the shooting and shifting electric cylinder is provided with a rotating shaft along the central axis, and the rotating shaft slidably passes through a guide sleeve, and the guide sleeve guides the shaft to slide along the central axis and limits the rotation of the rotating shaft.

[0021] In this technical solution, the guide sleeve is used to provide precise guidance and limiting for the rotating shaft, ensuring the accuracy of the rotating shaft during the sliding process. In addition to guiding the sliding, the guide sleeve also plays a role in limiting the rotation of the rotating shaft, which is used to maintain the stability of the rotating shaft when transmitting power and prevent it from generating unnecessary vibration due to rotation.

[0022] In some embodiments, the shell includes a limiting boss abutting against the outside of the linkage extrusion member, and the shell limits the two extreme positions of the driving member through the end faces of the limiting boss and the end faces of the guide sleeve, and the distance between the limiting boss and the guide sleeve is the maximum stroke of the driving member.

[0023] In this technical solution, in addition to ensuring that the linked extrusion does not exceed the preset range during the advancement stroke, the limit boss is also used to fix the entire housing so that it can be installed in the electric extrusion application scenario. The end face of the limit boss of the housing and the end face of the guide sleeve jointly define the two extreme positions of the driver, which represent the maximum extension and maximum contraction of the driver in the extrusion mechanism. The spacing between the guide sleeve and the limit boss defines the maximum stroke of the driver, which is used to achieve the best performance of the device in a specific application scenario. For example, in applications where the length of the extrusion needs to be precisely controlled, it is ensured that the device stops moving when the maximum stroke is reached, thereby avoiding excessive extension or contraction, improving the performance of the device, and enhancing the efficiency of the injection molding machine shooting table.

[0024] In some embodiments, the shell is further provided with a limiting track I matched with the limiting bearing I, a limiting track II matched with the limiting bearing II, and a circular channel matched with the linkage extrusion piece.

[0025] In the present technical solution, the shell is provided with a matching structure that meets the movement and control requirements of the device. For example, the matching of the limit track I and the limit bearing I ensures that the driving member moves along a predetermined trajectory on the screw to avoid deviation or shaking; for example, the matching of the limit track II and the limit bearing II is used to limit and guide the movement of the driving member, and the movement can be kept accurate even in the face of external interference or load changes; for example, the matching of the circular channel and the linkage extrusion member is used to ensure that the linkage extrusion member moves freely when pushing the driving member, thereby reducing friction and improving the movement efficiency of the extrusion member mechanism.

[0026] In some embodiments, the detection board I includes a photoelectric sensor, which is arranged adjacent to the conical gear I and electrically connected to the main control board. The photoelectric sensor records the gear number during the rotation of the conical gear I.

[0027] In this technical solution, the detection board I is used to detect the rotation state of the conical tooth I and convert it into an electrical signal output, ensuring that the main control board timely adjusts the control strategy of the shooting and shifting electric cylinder according to actual conditions, thereby achieving efficient operation of the device.

[0028] In some embodiments, the detection board II includes a plurality of sensors, which are arranged adjacent to the magnet and electrically connected to the main control board, and the plurality of sensors are arranged at intervals within the range of motion of the magnet.

[0029] In this technical solution, the detection board II uses several sensors to monitor the position change of the magnet within the range of motion, so as to achieve accurate perception of the motion state of the magnet. The sensors arranged at intervals not only improve the accuracy of position detection, but also help to achieve continuous detection of the motion trajectory of the magnet; the magnet position information captured by the sensor is transmitted to the main control board, which provides an important basis for the main control board to control the motion state of the device. Among them, the sensor uses the Hall effect for non-contact detection, and can sense the magnetic field change without direct contact with the magnet, which not only improves the service life of the sensor, but also reduces the error caused by friction and wear; in addition, the sensor has high sensitivity and response speed, quickly captures the change of the magnet position, and reflects the motion state of the magnet in real time and accurately. As a magnetic field source, the magnet generates a changing magnetic field during its movement. The magnetic field change is captured by the sensor and converted into an electrical signal, thereby realizing the detection of the motion state of the magnet. The motion state of the magnet (such as position, speed, etc.) is reflected by the change of the magnetic field it generates; the sensor on the detection board II indicates the motion state of the magnet by monitoring these changes. Based on the data provided by the sensor, the main control board adjusts the motion strategy of the device in real time to ensure that the magnet moves according to the predetermined trajectory, so that the device can achieve efficient motion control.

[0030] In some embodiments, a communication module is provided on the main control board, and the communication module is connected to the control terminal wirelessly. The communication module sends the current position information to the control terminal and controls the power output by the shooting electric cylinder through the control terminal.

[0031] In this technical solution, the communication module set on the main control board enables the device to communicate wirelessly with the external control terminal, which not only improves the flexibility and convenience of the device, but also makes remote control possible. The control terminal, as the remote control center of the device, receives the position information from the communication module in real time, and adjusts the output power of the shooting electric cylinder based on this information, so that the operator can control it from a place far away from the device, improving work efficiency and safety.

[0032] Another aspect of the present application provides an injection molding machine shooting table electric drive extrusion system, including the following components:

[0033] The control terminal is used to send preset position information, and adopts a wired control device and / or a wireless remote control device. The wired control device is connected to the main control board by wire, and the wireless remote control device is connected to the main control board by wireless.

[0034] In this technical solution, the control terminal provides both wired and wireless control modes to meet the usage requirements in different scenarios and is more intelligent. The wired control device is connected to the main control board through a physical line, with high stability and fast transmission speed; the wireless remote control device communicates with the main control board through wireless signals, providing higher flexibility and convenience. The control terminal has a user interaction interface, allowing the user to intuitively view the current position, speed and other status information of the extruded part, as well as perform parameter setting and troubleshooting operations. After receiving the preset position information from the control terminal, the main control board calculates the control instructions of the shooting and displacement electric cylinder required to achieve the preset position, which is used to coordinate the work of various components to achieve precise movement of the extruded part; it communicates with the control terminal by wire or wireless means, and also communicates with other components such as the shooting and displacement electric cylinder and sensors.
