Technical Field

[0003] This application relates to the field of mold frame equipment technology, and in particular to an integral rotating mold frame, a lower mold frame rotation control system and control method. Background Technology

[0004] With the development of industrial automation and precision manufacturing technology, the design and functionality of mold frames, as the support mechanism for molds, have received widespread attention.

[0005] In existing mold base designs, many mold bases are designed with a flip-up structure to facilitate operations such as mold cleaning and insert placement by operators. However, the rotation angle control of the lower mold in current mold bases is not precise enough, resulting in significant deviations in the actual lower mold base after rotation. Robots on some existing automated production lines require precise angle control to ensure accurate insert placement and rapid mold closing operations. Therefore, the poor rotational accuracy of existing rotatable mold bases limits their application in such automated production lines. Summary of the Invention

[0006] To address one or more of the problems existing in the prior art, a first aspect of this application provides a lower mold frame rotation control system for controlling the rotation angle of the lower mold frame on a rotating support connected thereto, comprising:

[0007] The lower mold frame includes a lower mold frame rotation center for connection with a rotating support;

[0008] The human-computer interaction unit is used to input basic data;

[0009] The control unit, connected to the human-machine interaction unit, is used to calculate the rotation angle based on the basic data and output a control signal to the drive unit.

[0010] A drive unit is connected to the lower mold frame and the control unit respectively, and is used to control the rotation of the lower mold frame according to the received control signal;

[0011] The drive unit includes a lower mold frame drive component and a lower mold frame transmission component. The lower mold frame transmission component includes a first crank and a first connecting rod. One end of the first crank is connected to the lower mold frame drive component, and the other end of the first crank is connected to one end of the first connecting rod. The other end of the first connecting rod is connected to the lower mold frame. The lower mold frame is driven by the lower mold frame drive component, thereby rotating about the rotation center of the lower mold frame.

[0012] The basic data includes the preset rotation angle θIN_Degree_Shift of the lower mold base drive component or the preset rotation angle θIN_Degree_Plate of the lower mold base.

[0013] The method for calculating the rotation angle based on the aforementioned basic data includes:

[0014] Calculate intermediate variables;

[0015] When the basic data includes the preset rotation angle θIN_Degree_Shift of the lower mold base drive component, calculate the corresponding rotation angle θOut_Degree_Plate of the lower mold base; or

[0016] When the basic data includes the preset rotation angle θIN_Degree_Plate of the lower mold frame, the corresponding rotation angle θOut_Degree_Shift of the lower mold frame drive component is calculated.

[0017] The lower mold frame rotation control system provided in this application achieves precise control of the lower mold frame rotation angle by integrating an advanced human-machine interface unit and control unit. The system can automatically calculate and generate corresponding control signals based on the preset rotation angle of the lower mold frame drive component or the preset rotation angle of the lower mold frame itself input by the operator, thereby driving the lower mold frame to rotate precisely. This precise control not only improves production efficiency and product quality but also reduces the need for manual adjustments, lowering the risk of errors and equipment failures caused by improper operation.

[0018] In some embodiments of this application, the basic data further includes: the zero-position coordinates (A, B) of the first connecting rod fixing point and the zero-position coordinates (C, D) of the lower mold frame drive shaft center in a coordinate system established with the lower mold frame rotation center as the origin, as well as the lengths of the first crank and the first connecting rod. By inputting the zero-position coordinates of the first connecting rod fixing point and the lower mold frame drive shaft center, as well as the lengths of the first crank and the first connecting rod, the system can accurately describe the geometric relationship of the lower mold frame transmission mechanism. These data provide the basis for subsequent calculations and ensure the accuracy of the calculations.

[0019] The intermediate variables for the calculation include:

[0020] Based on the zero-position coordinates of the first connecting rod fixing point and the lower mold frame drive shaft center, the zero-position angle A1 between the straight line determined by the first connecting rod fixing point and the lower mold frame drive shaft center and the horizontal direction is calculated.

[0021] Based on the zero-position coordinates of the first connecting rod fixing point and the center of the lower mold frame drive component shaft, the zero-position length L1 of the line connecting the first connecting rod fixing point and the center of the lower mold frame drive component shaft is calculated.

[0022] The zero-position angle A2 is calculated based on the zero-position length L1, the length of the first connecting rod, and the length of the first crank, which is the angle between the straight line determined by the fixed point of the first connecting rod and the center of the lower mold base drive shaft and the straight line determined by the center of the connecting shaft and the center of the lower mold base drive shaft.

[0023] Based on the zero-position angles A1 and A2, the zero-position angle A3 between the straight line determined by the center of the lower mold base drive shaft and the center of the connecting shaft and the vertical direction is calculated.

[0024] Based on the zero-position coordinates (C, D) of the lower mold base drive shaft center, the length of the first connecting rod, and the zero-position angle A3, calculate the zero-position coordinates (Middle_Shift_X, Middle_Shift_Y) of the connecting shaft center.

[0025] The zero-position length L3 is calculated based on the zero-position coordinate value of the first connecting rod fixing point.

[0026] These detailed geometric parameter inputs and intermediate variable calculations enable the system to adapt to lower mold base transmission mechanisms of different sizes and structures, enhancing the system's versatility and adaptability. Regardless of mold type or production environment, the system provides precise control, improving production efficiency and product quality.

[0029] Based on the instantaneous coordinates of the center of the connecting shaft, the instantaneous distance L2 from the center of the connecting shaft to the rotation center of the lower mold frame is calculated.

[0030] Based on the zero-position length L3, instantaneous distance L2, and first crank length, the instantaneous angle A5 is calculated as the angle between the straight line determined by the first connecting rod fixing point and the lower mold base rotation center and the straight line determined by the connecting shaft center and the lower mold base rotation center.

The drive unit 300 may include a motor controller, power management circuitry, and any necessary sensors to monitor the status during the drive process.

[0130] Referring to Figures 2 and 6, the lower mold frame 3 includes a lower mold frame rotation center 32 for connection with the rotating support 2.

[0131] Referring to Figure 2, the drive unit 300 includes a lower mold frame drive component 33 and a lower mold frame transmission component 34. The lower mold frame transmission component 34 includes a first crank 341 and a first connecting rod 342. One end of the first crank 341 is connected to the lower mold frame drive component 33, and the other end of the first crank 341 is connected to one end of the first connecting rod 342. The other end of the first connecting rod 342 is connected to the lower mold frame 34. The lower mold frame 3 is driven by the lower mold frame drive component 33, thereby rotating around the lower mold frame rotation center 32.

[0132] When the drive unit 300 receives a control signal from the control unit 200, the lower mold frame drive component 33 is activated and begins to rotate. Since the first crank 341 is movably connected to the lower mold frame drive component 33, it is driven to rotate. The first connecting rod 342 is also movably connected to the first crank 341; therefore, when the first crank 341 rotates, the first connecting rod 342 also rotates. One end of the lower mold frame 3 is movably connected to the first connecting rod 342, and the other end is rotatably mounted on a fixed mold frame via the lower mold frame rotation center 32. Therefore, when the first connecting rod 342 rotates, the lower mold frame 3 rotates around the lower mold frame rotation center 32, thus achieving the rotation of the lower mold frame 3.

[0133] The lower mold frame drive component 33 can be a motor or other power component.

[0134] The basic data input by the operator through the human-machine interaction unit 100 includes: the preset angle of rotation of the lower mold base drive component θIN_Degree_Shift or the preset angle of rotation of the lower mold base θIN_Degree_Plate.

[0135] In some embodiments, the basic data input by the operator through the human-machine interface unit 100 further includes: the zero coordinate values ​​(A, B) of the first connecting rod fixing point 342′ and the zero coordinate values ​​(C, D) of the lower mold frame drive shaft center 33′ in a coordinate system with the lower mold frame rotation center 32 as the origin, as well as the first crank length L4 and the first connecting rod length L5, and the desired lower mold frame drive rotation angle θOut_Degree_Shift, the desired lower mold frame rotation angle θOut_Degree_Plate, or other relevant data.

[0136] The first connecting rod fixing point 342′ is the connection point between the first connecting rod 342 and the lower mold frame 3.

[0137] In some embodiments of this application, to facilitate a more intuitive explanation of the angle calculation method, the initial state of the lower mold frame structure shown in Figure 2 (i.e., the state in which the lower mold frame is placed horizontally) is abstracted into the structure shown in Figure 3.

The formula used in this step is as follows:

[0145] The zero-position angle A2 is calculated based on the zero-position length L1, the first connecting rod length L5, and the first crank length L4.

The formula used in this step is as follows:

[0146] The lower mold frame transmission component connecting shaft center 34′ is the connection point between the first crank 341 and the first connecting rod 342.

[0147] Based on the zero-position angles A1 and A2, the zero-position angle A3 between the straight line determined by the center of the lower mold base drive shaft 33′ and the center of the connecting shaft and the vertical direction is calculated. The formula used in this step is as follows:

[0148] A3 = 90° - A2 + A1

The formula used in this step is as follows:

[0157] Through the aforementioned control system and calculation method, the operator can input various basic data, including the desired lower mold frame drive component rotation preset angle θIN_Degree_Shift, via the human-machine interface unit 100. The control unit 200 calculates the final lower mold frame rotation angle θOut_Degree_Plate after the lower mold frame drive component 33 rotates by that angle based on the input basic data and the aforementioned calculation method. At this time, the operator can feed back the calculated lower mold frame rotation angle to the operator through the human-machine interface 100, control the lower mold frame drive component to rotate the preset angle θIN_Degree_Shift, or perform new calculations according to user instructions.

[0158] When the input basic data includes the preset rotation angle θIN_Degree_Plate of the lower mold base, step S200' is performed after step S100. Based on the basic data and intermediate variables, the corresponding rotation angle θOut_Degree_Shift of the lower mold base drive component is calculated. This step includes:

[0159] Based on the zero-position coordinates (A, B) of the first connecting rod fixing point 342′, the zero-position angle A7 of the angle between the straight line formed by the first connecting rod fixing point 342′ and the lower mold base rotation center 32 and the horizontal direction is calculated. The formula used in this step is as follows:

[0160] Based on the zero-position angle A7 and the preset rotation angle θIN_Degree_Plate of the lower mold base, the instantaneous angle A7_a between the straight line formed by the first connecting rod fixing point 342′ and the rotation center 32 of the lower mold base after the preset rotation angle θIN_Degree_Plate of the lower mold base and the horizontal direction is calculated. The formula used in this step is as follows:

[0161] A7_a=A7+θIN_Degree_Plate

[0162] Based on the zero-position length L3 and the instantaneous angle A7_a, the instantaneous coordinate values ​​(Middle_Shift_X_a, Middle_Shift_Y_a) of the first connecting rod fixed point 342′ after the lower mold frame rotates by the preset angle θIN_Degree_Plate are calculated. The formula used in this step is as follows:

[0163] The instantaneous length L1_a of the line connecting the first connecting rod fixed point 342′ and the lower mold base drive component shaft center 33′ is calculated based on the instantaneous coordinate values ​​(Middle_Shift_X_a, Middle_Shift_Y_a) of the first connecting rod fixed point 342′ after the lower mold base rotates by a preset angle θIN_Degree_Plate, and the zero-position coordinate values ​​(C, D) of the lower mold base drive component shaft center 33′. The formula used in this step is as follows:

[0164] Based on the instantaneous length L1_a, the length of the first connecting rod L5, and the length of the first crank L4, the instantaneous angle A2_a is calculated as the angle formed by the straight line between the fixed point 342′ of the first connecting rod and the center 33′ of the lower mold base drive shaft after the lower mold base rotates by a preset angle θIN_Degree_Plate, and the straight line between the center 34′ of the lower mold base transmission shaft and the center 33′ of the lower mold base drive shaft. The formula used in this step is as follows:

[0166] The instantaneous angle A1_a between the straight line determined by the first connecting rod fixing point 342′ and the lower mold frame drive component shaft center 33′ after the lower mold frame rotates by a preset angle θIN_Degree_Plate and the horizontal direction, and the instantaneous angle A2_a between the straight line determined by the first connecting rod fixing point 342′ and the lower mold frame drive component shaft center 33′ after the lower mold frame rotates by a preset angle θIN_Degree_Plate and the straight line determined by the lower mold frame transmission component connecting shaft center 34′ and the lower mold frame drive component shaft center 33′, are used to calculate the instantaneous angle A3_a between the straight line determined by the lower mold frame drive component shaft center 33′ and the lower mold frame transmission component connecting shaft center 34′ after the lower mold frame rotates by a preset angle θIN_Degree_Plate and the vertical direction. The formula used in this step is as follows:

[0171] In some embodiments of this application, the memory inside the control unit 200 stores a computer program to implement the above method, and the computer program is as follows:

[0172] The second aspect of this application provides a method for controlling the rotation of a lower mold base. This method enables precise control of the rotation of the lower mold base, thereby improving production efficiency. Specifically, it includes the following steps:

[0173] S1, Input Data

[0174] The operator inputs necessary data through the human-computer interaction unit. This data includes at least:

[0175] The zero-position coordinates (A, B) of the first link fixed point in the coordinate system established with the rotation center of the mold frame as the origin are shown below.

[0176] Zero-position coordinates (C, D) of the lower mold base drive component axis center.

[0177] First crank length L4

[0178] First link length L5

[0179] In addition, the operator can input a preset rotation angle of the lower mold base (θIN_Degree_Plate) or a preset rotation angle of the lower mold base drive component (θIN_Degree_Shift) via the human-machine interface unit, as well as other relevant parameters. The human-machine interface unit has a display function that can show the system status, operation menu, and input interface, as well as input functions, allowing the operator to input various required parameters.

[0180] S2. Calculate the lower mold base drive component or the rotation angle of the lower mold base, and generate the corresponding control signal.

[0181] The control unit receives basic input data from the human-machine interface unit and performs a series of calculations based on this data. When the input basic data includes a preset rotation angle θIN_Degree_Shift for the lower mold base drive component, the corresponding rotation angle θOut_Degree_Plate for the lower mold base is calculated based on the basic data and intermediate variables; or

[0182] When the basic data includes the preset rotation angle θIN_Degree_Plate of the lower mold frame, the corresponding rotation angle θOut_Degree_Shift of the lower mold frame drive component is calculated based on the basic data and intermediate variables.

[0183] S3. Drive the lower mold base drive component to rotate according to the control signal, thereby driving the lower mold base to rotate.

[0184] The drive unit receives a control signal from the control unit and drives the lower mold base drive component to rotate according to the signal. The rotation of the lower mold base drive component is transmitted to the lower mold base through the lower mold base transmission component (including the first crank and the first connecting rod), causing the lower mold base to rotate around the lower mold base rotation center, thereby achieving precise angle adjustment of the lower mold base.

[0185] Figure 4 shows a schematic diagram of an overall rotating mold frame structure provided in an embodiment of this application, and Figure 5 shows a schematic diagram of the bottom frame structure of an overall rotating mold frame provided in an embodiment of this application.

[0186] Please refer to Figures 4 and 5. A third aspect of this application provides an integral rotating mold frame, including the system in the above embodiments, and further including: a base frame 1, a rotating support 2, and an upper mold frame 4;

[0187] The base frame 1 is the fundamental support structure of the overall rotating mold frame, used to bear the entire weight of the rotating support 2, lower mold frame 3, and upper mold frame 4, and to ensure the stability and reliability of the entire mold frame. The base frame 1 is usually made of high-strength steel, with sufficient rigidity and durability to withstand the high pressure and high temperature generated during the injection molding process.

[0188] The rotating bracket 2 is rotatably connected to the base frame 1 at the bracket rotation center 22 via the bracket rotation assembly 21. The bracket drive component 23 drives the rotating bracket 2 to rotate around the bracket rotation center 22 as the axis, realizing a wide range of angle adjustments for the overall mold frame. The bracket drive component 23 can be an electric motor, a hydraulic motor, or other form of power device. By precisely controlling the rotation angle, the stability and accuracy of the rotating bracket 2 at different positions are ensured.

[0189] Figure 6 shows a schematic diagram of the assembly structure of the rotating support, upper mold frame and lower mold frame in one rotating state of the overall rotating mold frame provided in one embodiment of this application. Figure 7 shows a schematic diagram of the overall rotating mold frame structure from another angle provided in the embodiment.

[0190] In a specific example, referring to Figures 6 and 7, the bracket rotation assembly 21 includes a first rotating shaft 211 and a first bearing component 212. The first bearing component 212 is fixed on the base frame 1, one end of the first rotating shaft 211 is connected to the first bearing 212, and the other end is connected to the rotating bracket 2 at the bracket rotation center 22, so that the rotating bracket 2 can rotate.

[0191] With a wide range of angle adjustments, the rotary support can adapt to different injection molding machine and production line layouts, improving production flexibility. For example, when producing different models of automotive parts, the mold position can be optimized by adjusting the angle of the rotary support, thereby improving production efficiency and product quality.

[0192] In some embodiments of this application, referring to Figures 4 and 5, two support drive members 23 are disposed on both sides of the base frame 1. Each support drive member 23 is connected to the rotating support 2 via a support transmission member 24 to drive the rotating support 2 to rotate. By placing the support drive members 23 on the base frame 1, the installation of the drive members can be ensured to be stable, vibration and displacement can be reduced, and the overall system stability can be improved.

[0193] In some embodiments of this application, referring to Figures 4 and 5, the bracket transmission component 24 includes a drive gear 241 and an arc-shaped rack 242 meshing with the drive gear. The drive gear 241 is driven by the output shaft of the bracket drive component 23; the arc-shaped rack 242 is fixedly connected to the rotating bracket 2.

[0194] The drive gear 241 typically employs high-precision gears, such as helical gears or herringbone gears, to ensure low noise and high precision during transmission. The design of the arc-shaped rack 242 ensures that the rotating support 2 remains engaged with the drive gear 241 throughout rotation, guaranteeing the continuity and stability of the transmission.

[0195] In some embodiments of this application, referring to Figures 4 to 6, the arc-shaped rack 242 is provided with a limiting member 2421. The limiting member 2421 is used to limit the range of motion of the arc-shaped rack 242 and prevent excessive rotation. The limiting member 2421 can be a mechanical stop, a limit switch, or other form of physical obstacle used to limit the range of motion of the arc-shaped rack 242. The setting of the limiting member 2421 improves the safety of the system, prevents excessive rotation caused by improper operation or control system failure, and ensures stable operation of the rotating bracket 2 within a predetermined working range by limiting the range of motion of the arc-shaped rack 242, thereby improving the reliability and lifespan of the system.

[0196] The lower mold holder 3 is rotatably connected to the rotating support 2 at the lower mold holder rotation center 32 via the lower mold holder rotation assembly 31. The lower mold holder drive 33 drives the lower mold holder 3 to rotate around the lower mold holder rotation center 32, thereby adjusting the angle of the lower half of the mold. The lower mold holder drive 33 can be an electric motor, a hydraulic motor, or other form of power device. By precisely controlling the rotation angle, the stability and accuracy of the lower mold holder in different positions are ensured.

[0197] In a specific example, referring to Figures 2 and 6, the lower mold frame rotating assembly 31 includes a second rotating shaft (not shown) and a second bearing member 312. The second bearing member 312 is fixed on the rotating bracket 2 to reduce friction during rotation. One end of the second rotating shaft is connected to the second bearing 312, and the other end is connected to the lower mold frame 3 at the rotation center 32 of the lower mold frame, so that the lower mold frame 3 can rotate.

[0198] By adjusting the angle of the lower mold base 3, it can better adapt to complex mold structures. For example, during insert injection molding, inserts can be placed more easily, improving the positioning accuracy of the inserts. In addition, the independent rotation function of the lower mold base 3 also facilitates mold cleaning and maintenance.

[0199] In some embodiments of this application, referring to Figures 2 and 6, two lower mold frame drive members 33 are disposed on both sides of the rotating bracket 2. Each lower mold frame drive member 33 is connected to the lower mold frame 3 through a lower mold frame transmission member 34 to drive the lower mold frame 3 to rotate.

[0200] The connection point between the lower mold frame drive component 33 and the lower mold frame 3 via the lower mold frame transmission component 34 should be at a certain distance from the rotation center 32 of the lower mold frame. This allows the driving force at the connection point to drive the lower mold frame 3 to rotate around the rotation center 32 of the lower mold frame.

[0201] The lower mold base drive unit 33 can be an electric motor, a hydraulic motor, or a pneumatic motor, depending on the load and accuracy requirements of the application. For example, a hydraulic motor can be selected for applications requiring high torque and low speed, while a servo motor can be selected for applications requiring high precision and fast response.

[0202] By mounting the lower mold holder drive component 33 on the rotating bracket 2, space can be saved, making the entire device more compact. This mounting method allows the lower mold holder drive component 33 to rotate together with the rotating bracket 2, adapting to different working positions and improving flexibility.

[0203] In some embodiments of this application, referring to Figures 2 and 6, the lower mold frame transmission component 34 includes: a first crank 341 and a first connecting rod 342, one end of the first crank 341 being connected to the lower mold frame drive component 33; one end of the first connecting rod 342 being connected to the other end of the first crank 341, and the other end of the first connecting rod 342 being connected to the lower mold frame 3.

[0204] The main function of the first crank 341 is to convert the rotational motion of the lower mold base drive 33 into reciprocating motion. By adjusting the length of the first crank 341, the stroke and speed of the lower mold base 3 can be changed. The main function of the first connecting rod 342 is to transmit the reciprocating motion of the first crank 341 to the lower mold base 3, so as to achieve precise rotation of the lower mold base 3.

[0205] The upper mold frame 4 is rotatably connected to the rotating support 2 at the upper mold frame rotation center 42 via the upper mold frame rotation assembly 41. The upper mold frame drive 43 drives the upper mold frame 4 to rotate around the upper mold frame rotation center 42, thereby adjusting the angle of the upper part of the mold. The upper mold frame drive 43 can be an electric motor, a hydraulic motor, or other form of power device. By precisely controlling the rotation angle, the stability and accuracy of the upper mold frame in different positions are ensured.

[0206] Figure 8 shows a schematic diagram of the upper mold frame structure of the integral mold frame in one direction according to an embodiment of this application; Figure 9 shows a schematic diagram of the upper mold frame structure of the integral mold frame in another direction according to an embodiment of this application; Figure 10 shows a schematic diagram of the assembly structure of the rotating support, upper mold frame and lower mold frame in another state of the integral mold frame according to an embodiment of this application; Figure 11 is a cross-sectional view along section line AA in Figure 10; Figure 12 is an enlarged view of point B in Figure 11.

[0207] In a specific example, referring to Figures 6, 8 to 12, the upper mold frame rotating assembly 41 includes a third rotating shaft 411 and a third bearing 412. One end of the third rotating shaft 411 is fixed to the upper mold frame 4, and the third bearing 412 is fixed to the lifting slide plate 25 of the rotating bracket 2. The other end of the third rotating shaft 411 cooperates with the third bearing 412 to enable the upper mold frame 4 to rotate. While the lifting slide plate 24 of the rotating bracket 2 is moving up and down, it can drive the upper mold frame 4 to move up and down, so that the half mold on the upper mold frame 4 can perform mold closing and mold opening operations with the half mold on the lower mold frame 3.

[0208] By adjusting the angle of the upper mold base 4, the mold closing and opening process can be optimized, improving the precision and speed of injection molding. For example, when producing electronic device housings, adjusting the angle of the upper mold base can ensure tight mold closure, thereby reducing flash and burrs.

[0209] The overall rotating mold frame provided in the above embodiments of this application realizes flexible adjustment of the mold in multiple directions through a multi-layered rotating structure, which is suitable for the production of complex-shaped products; the modular design makes each component easy to disassemble and maintain, reducing maintenance costs and downtime; it is suitable for a variety of injection molding application scenarios, such as injection molding of automotive parts, injection molding of electronic device housings, etc.

[0210] In some embodiments of this application, referring to Figures 6, 8 to 12, two upper mold frame drive members 43 are disposed on both sides of the upper mold frame 4. Each upper mold frame drive member 43 is connected to the rotating bracket 2 through the upper mold frame transmission member 44 to drive the upper mold frame 4 to rotate.

[0211] The upper mold frame drive component 43 can be fixedly mounted on the upper mold frame 4. The connection point of the upper mold frame drive component 43 and the rotating bracket 2 connected through the upper mold frame transmission component 44 is at a certain distance from the upper mold frame rotation center 42 of the upper mold frame 4, so that the upper mold frame 4 can be rotated around the upper mold frame rotation center 42 by the reaction force of the force output by the upper mold frame drive component 43 at the upper mold frame rotation center 42.

[0212] In some embodiments of this application, the upper mold frame transmission component 44 includes: a second crank 441 and a second connecting rod 442, one end of the second crank 441 being connected to the upper mold frame drive component 43; one end of the second connecting rod 442 being connected to the other end of the second crank 441, and the other end of the second connecting rod 442 being connected to the lifting slide plate 25 of the rotating bracket 2.

[0213] The main function of the second crank 441 is to convert the rotary motion of the upper mold base drive 43 into reciprocating motion. By adjusting the length of the second crank 441, the stroke and speed of the upper mold base 4 can be changed. The length and angle of the second crank 441 can be adjusted by an adjustment mechanism to adapt to different working requirements.

[0214] The main function of the second connecting rod 442 is to transmit the force generated by the reciprocating motion of the second crank 441 to the lifting slide plate 25 of the rotating support 2, and through the reaction force, to drive the rotation of the upper mold frame 4. By adjusting the length and angle of the second crank 441, the motion parameters of the upper mold frame 4 can be easily changed to adapt to different processing requirements.

[0221] Rotation motion of rotating bracket 2:

[0222] Start bracket drive 23: The bracket drive 23 (which can be an electric motor, hydraulic motor, etc.) starts, and its output shaft drives the drive gear 241 to rotate.

[0223] Gear transmission: The drive gear 241 meshes with the arc-shaped rack 242, transmitting the rotational motion to the arc-shaped rack 242.

[0224] Rotation of the rotating bracket 2: The arc-shaped rack 242 is fixedly connected to the rotating bracket 2, and its movement drives the rotating bracket 2 to rotate around the bracket rotation center 22. The limiting member 2421 restricts the range of motion of the arc-shaped rack 242 to prevent excessive rotation and ensure that the rotating bracket 2 operates stably within the predetermined working range.
