[0002] When multiple template opening actions need to be completed on the mold, not only the assistance of related equipment is required, but sometimes an additional oil cylinder needs to be installed in the mold to complete the mold action. However, if the oil cylinder is installed in the template, hydraulic oil needs to be provided through the oil circuit in the template to output power to the oil cylinder through the hydraulic oil.

[0003] At present, during the mold hot forming process, the overall equipment will generate large vibrations, especially when the high-pressure cylinder is frequently extended and retracted. The conventional fixing device only uses simple bolt connections or rigid clamps, making it difficult for the overall device to effectively buffer and absorb these vibrations, resulting in loose connection parts of the cylinder during long-term use, affecting its positioning accuracy, and then causing deviations in the opening and closing actions of the mold, affecting the quality and dimensional accuracy of the molded product. In addition, the temperature will change dramatically during mold hot forming, and the conventional fixing method cannot adapt to this change well, resulting in excessive squeezing of the cylinder in conventional clamping at high temperatures, and deformation of the cylinder at low temperatures, resulting in a gap between the fixed clamp and the cylinder, resulting in damage to the cylinder during long-term fixing operations, affecting the service life of the cylinder. Therefore, it is necessary to propose a cylinder fixing device for mold hot forming. Summary of the invention

In addition, the temperature will change dramatically during mold thermoforming, and the conventional fixing method cannot adapt to this change well, resulting in excessive squeezing of the cylinder in conventional clamping at high temperatures, and deformation of the cylinder at low temperatures, resulting in a gap between the fixed clamp and the cylinder, resulting in damage to the cylinder during long-term fixing operations, affecting the service life of the cylinder.

When the frequent telescopic movements of the oil cylinder oil circuit control structure cause the overall mold equipment to vibrate, the frequency modulation generator installed at the front end emits high-frequency or low-frequency waves that are similar but opposite in phase to the generated vibration frequency, so that the two interact with each other and offset part of the generated vibration source; An adaptive fixing component is installed on the top of the stress bearing seat and is connected by an elastic column and a frame body on the side of the slotted flexible metal stacking frame.

[0010] Preferably, the active control component includes: A stabilizing frame, an annular guide rail, a positioning sliding seat and a vibration source detection sensor, wherein the vibration source detection sensor is installed on the side wall surface of the positioning sliding seat, the annular guide rail is located at the top of the stabilizing frame to form a fastening connection, the two sides of the bottom end of the stabilizing frame and the top of the slotted flexible metal stacking frame form a fastening connection, and an electrically controlled adjustment arm is installed at the bottom of the positioning sliding seat.

[0011] Preferably, the side end of the electrically controlled regulating arm and the frequency modulation generator form an installation arrangement, and the side end of the forearm of the electrically controlled regulating arm is installed with a frequency modulation control processor.

[0012] Preferably, the frequency modulation control processor detects the vibration source position point generated when the cylinder oil circuit control structure operates according to the vibration source detection sensor, and feeds back the detection data to the frequency modulation control processor, so that the frequency modulation control processor issues a control instruction to the frequency modulation control processor to control the operating intensity and frequency of the frequency modulation generator.

[0013] Preferably, a transverse sliding guide rail is installed at the bottom of the slotted flexible metal stacking frame, and the transverse sliding guide rail is used to drive the slotted flexible metal stacking frame and its internal related structures to form an automated positioning installation connection with the mold during the installation and disassembly process.

[0014] Preferably, a magnetostrictive driver is installed at the bottom side end of the stress bearing seat, and the magnetostrictive driver is located on the outer peripheral side of the cylinder oil circuit control structure to form a symmetrical installation.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, when the temperature of the mold increases and the oil cylinder oil circuit control structure produces thermal deformation, the force rod, the position cylinder and the adjusting rod are used to make corresponding adjustments, so that when the oil cylinder deviates to the right due to vibration, the position cylinder will push the adjusting rod to move to the left to compensate for the deviation. During the adjustment process, the micron-level offset rangefinder monitors the displacement of the adjusting rod in real time to ensure its accuracy. During the movement of the adjusting rod, if a large impact force is generated, the liquid buffer, the side end of the buffer cavity and the contact force detection sensor are used to analyze and judge the overall fixing state. Then, when the temperature of the mold increases, the memory metal abutment block expands and changes shape appropriately according to the increase in temperature to better fit the surface of the oil cylinder. At the same time, the magnetic repulsion mounting frame The magnetic repulsion generated by the two groups of permanent magnets inside provides a certain elastic support and adaptive adjustment space for the memory metal abutment block, so that when the oil cylinder undergoes a large size change due to thermal expansion and contraction, the memory metal abutment block can flexibly adjust the contact pressure and fit degree with the oil cylinder within a certain range under the repulsive force of the permanent magnet, which not only ensures tight fixation, but also avoids damage to the oil cylinder due to excessive extrusion. The side pressure pushes the abutment frame to transmit the force detected by the contact force detection sensor and the stress it is subjected to to the slotted flexible metal stacking frame through the elastic column, thereby realizing the coordinated adjustment of the stresses among the various parts of the entire fixing device. If the contact force on one side is too large, part of the stress can be dispersed to the slotted flexible metal stacking frame through the elastic deformation of the elastic column, so as to achieve an overall balanced and stable fixed state.

[0016] 2. In the present invention, by cooperating with the soft pressure contact fixing component, the elastic abutment column applies a certain pre-pressure to the flexible damping contact plate in the initial state, so that the flexible damping contact plate maintains slight contact with the surface of the oil cylinder oil circuit control structure. When the above-mentioned oil cylinder oil circuit control structure is deformed due to heat or force, the edge contact frame, the contact force detection sensor and the micro-propulsion guide rod are used to make the micro-propulsion guide rod contract when the contact force increases, driving the reciprocating rack fastened to its side end to move forward. Since the reciprocating rack is meshed with the rotating pinion, the rotating pinion will rotate accordingly, thereby relaxing the elastic abutment column, reducing the pressure on the flexible damping contact plate, and then reducing the pressure on the oil cylinder oil circuit control structure. The contact pressure of the oil cylinder oil circuit control structure is increased, and vice versa, the elastic abutment column is tightened, increasing the pressure on the flexible damping contact plate, and increasing the contact pressure on the oil cylinder oil circuit control structure, thereby realizing soft contact fixation with the oil cylinder oil circuit control structure. After the adaptive fixing component has made a major adjustment to the position of the oil cylinder oil circuit control structure, the side pressure can push the abutment frame through its micro-drive structure, prompting the micro-propulsion guide rod to make corresponding secondary adjustments, so as to ensure that the soft pressure contact fixing component and the oil cylinder oil circuit control structure always maintain the best contact state and fixing effect, realize dynamic balance, ensure the service life of the oil cylinder oil circuit control structure, form a linkage synergistic effect, and jointly provide all-round and high-precision fixation and protection for the oil cylinder oil circuit control structure.

[0017] 3. In the present invention, when the hot forming operation of the mold starts, the vibration source detection sensor, the frequency modulation control processor, and the magnetostrictive driver are used to detect that the cylinder has a vibration trend to the left. The PLC controller controls the magnetostrictive driver to produce a small deformation to the right on the right side of the cylinder to offset part of the vibration. Secondly, after receiving the data from the vibration source detection sensor, the frequency modulation control processor analyzes and judges, and the frequency modulation control processor calculates that the frequency modulation generator should generate an anti-phase wave with a similar frequency, appropriate amplitude and phase, and then makes the frequency modulation generator produce according to the instruction. The corresponding high-frequency or low-frequency waves interact with the waves generated by the vibration of the cylinder oil circuit control structure, so that near the vibration source, the anti-phase waves generated by the frequency modulation generator are superimposed on the cylinder vibration waves, so that the vibration amplitude of the synthetic wave is significantly reduced, thereby effectively offsetting part of the vibration energy. In the above process, the positioning sliding seat can be moved on the annular guide rail as needed, and the electronically controlled adjusting arm can adjust the position and angle of the frequency modulation generator to ensure that the anti-phase waves generated by the frequency modulation generator can accurately act on the vibration source area, thereby improving the effect of vibration offset and improving the molding accuracy and quality stability of the mold products.

[0022] Embodiment 2: In the present invention, according to Figure 1 , Figure 2 , Figure 4 - Figure 8 As shown, the adaptive fixing component 4 includes: The position cylinder 401, the force-bearing rod 4091, the high-strength alloy abutment frame 404 and the adjustment rod 403, the position cylinder 401 is mounted on the top of the stress bearing seat 8, the top of the adjustment rod 403 is installed with a micron-level offset rangefinder 402, and the left and right sides of the front end of the high-strength alloy abutment frame 404 are installed with magnetic repulsion mounting shell frames 405. The interior of the magnetic repulsion mounting shell frame 405 is composed of two groups of permanent magnets that form magnetic repulsion, and the front end of the magnetic repulsion mounting shell frame 405 is connected with a memory metal abutment block 406.

[0023] The side end of the adjusting rod 403 is fastened with a liquid buffer 407, the side end of the liquid buffer 407 is fastened with a buffer cavity 409, a contact force detection sensor 408 is installed inside the side end of the buffer cavity 409, the side end of the buffer cavity 409 is fastened with a side pressure push bracket 4090, and the side end bottom of the side pressure push bracket 4090 is connected to the elastic column 5.

[0024] The soft pressure contact fixing assembly 6 includes: The edge contact frame 601, the mounting groove 604, the elastic abutment column 602 and the flexible damping contact plate 603, the edge contact frame 601 forms a contact fit with the outer wall edge of the cylinder oil circuit control structure 3 through the memory metal, the mounting groove 604 is opened inside the edge contact frame 601, so that the elastic abutment column 602 drives the flexible damping contact plate 603 to be located inside the mounting groove 604 to form an equally divided and equidistant arrangement, and a micro-propulsion guide rod 605 is installed on the back side of the edge contact frame 601.

[0025] The micro-advancement guide rod 605 and the contact force detection sensor 408 form a signal connection, the side end of the micro-advancement guide rod 605 is fastened with a reciprocating rack 606, the bottom end of the reciprocating rack 606 is meshingly connected with a rotating pinion 607, the center end of the rotating pinion 607 and the elastic abutment column 602 form a connection setting, and the side end of the edge contact frame 601 and the side pressure push the micro-drive structure installed on the side wall surface of the abutment frame 4090 to form a connection setting.

[0026] In a specific solution, when the mold hot forming process is started, the oil cylinder oil circuit control structure 3 begins to frequently extend and retract and generate vibration. At the same time, when the oil cylinder oil circuit control structure 3 generates thermal deformation due to the increase in mold temperature, the force rod 4091 first senses the stress change caused by the vibration and deformation, and transmits the signal to the position cylinder 401 and the adjustment rod 403. The position cylinder 401 drives the adjustment rod 403 to perform corresponding extension and retraction actions according to the signal received by the PLC controller, so that when the oil cylinder deviates to the right due to vibration, the position cylinder 401 will push the adjustment rod 403 to move to the left to compensate for this deviation. During the adjustment process, the micron-level offset rangefinder 402 monitors the displacement of the adjustment rod 403 in real time to ensure its accuracy. During the movement of 403, if a large impact force is generated, the liquid buffer 407 will play a role, and the buffer medium inside it absorbs and dissipates part of the impact force by flowing and deforming, so that the force acting on the buffer cavity 409 is buffered. At the same time, the contact force detection sensor 408 at the side end of the buffer cavity 409 detects the size of the contact force in real time and transmits the data to the PLC controller of the entire device so as to analyze and judge the overall fixed state. Then, as the mold temperature rises, the memory metal abutment block 406 that is fixedly abutted against the outer wall of the cylinder oil circuit control structure 3 expands and changes its shape appropriately according to the increase in temperature to better fit the surface of the cylinder. At the same time, the magnetic repulsion generated by the two groups of permanent magnets in the magnetic repulsion mounting frame 405 is the memory metal. The metal abutment block 406 provides a certain elastic support and adaptive adjustment space, so that when the oil cylinder has a large size change due to thermal expansion and contraction, the memory metal abutment block 406 can flexibly adjust the contact pressure and fit degree with the oil cylinder within a certain range under the repulsive force of the permanent magnet, which not only ensures tight fixation, but also avoids damage to the oil cylinder due to excessive extrusion. The side response pressure pushes the abutment frame 4090 to transmit the force detected by the contact force detection sensor 408 and the stress it is subjected to to the slotted flexible metal laminate frame 1 through the elastic column 5, so as to realize the coordinated adjustment of the stresses among the various parts of the entire fixing device, so that if the contact force on one side is too large, part of the stress is dispersed to the slotted flexible metal laminate frame 1 through the elastic deformation of the elastic column 5, and at the same time, P The LC controller controls and adjusts the corresponding structures (position cylinder 401 and adjustment rod 403, etc.) to achieve an overall balanced and stable fixed state. Secondly, the edge contact frame 601 is tightly fitted with the outer wall side of the cylinder oil circuit control structure 3 through the characteristics of memory metal, so that the elastic abutment column 602 applies a certain pre-pressure to the flexible damping contact plate 603 in the initial state, so that the flexible damping contact plate 603 maintains a slight contact with the surface of the cylinder oil circuit control structure 3. When the above-mentioned mold hot forming operation starts, when the cylinder oil circuit control structure 3 is deformed due to heat or force, the edge contact frame 601 first senses this deformation and transmits a signal to the contact force detection sensor 408. The contact force detection sensor 408 detects the change of contact force in real time.And transmit the data to the PLC controller controlled by the instruction of the micro-advancing guide rod 605, so that the micro-advancing guide rod 605 can perform corresponding extension and retraction actions according to the data transmitted by the contact force detection sensor 408, that is, when the contact force increases, the micro-advancing guide rod 605 contracts, driving the reciprocating rack 606 fastened to its side end to move forward. Since the reciprocating rack 606 is meshed and connected with the rotating pinion 607, the rotating pinion 607 will rotate accordingly, thereby relaxing the elastic abutment column 602, reducing the pressure on the flexible damping contact plate 603, and then reducing the contact pressure on the oil cylinder oil circuit control structure 3. Conversely, if the contact force decreases, the micro-advancing guide rod 605 extends out, driving the reciprocating rack 606 to move backward, and the rotating pinion 607 rotates in the opposite direction, tightening the elastic abutment column 602, increasing the pressure on the flexible damping contact plate 603, and improving the contact pressure on the oil cylinder oil circuit control structure 3, thereby achieving contact with the oil. The soft contact fixation of the cylinder oil circuit control structure 3, wherein the side end of the edge contact frame 601 is connected with the micro-drive structure of the side pressure push frame 4090 and works in coordination, so that the side pressure push frame 4090 can further regulate the action of the micro-advancing guide rod 605 according to the stress state of the overall fixing device and the adjustment of the adaptive fixing component 4, so that after the adaptive fixing component 4 has made a large adjustment to the position of the cylinder oil circuit control structure 3, the side pressure push frame 4090 can, through its micro-drive structure, prompt the micro-advancing guide rod 605 to make a corresponding secondary adjustment, so as to ensure that the soft pressure contact fixing component 6 and the cylinder oil circuit control structure 3 always maintain the best contact state and fixing effect, achieve dynamic balance, ensure the service life of the cylinder oil circuit control structure 3, form a linkage synergistic effect, and jointly provide all-round, high-precision fixation and protection for the cylinder oil circuit control structure 3.

[0027] Embodiment 3: In the present invention, according to Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the active control component 2 includes: A stabilizing frame 201, an annular guide rail 202, a positioning sliding seat 203 and a vibration source detection sensor. The vibration source detection sensor is installed on the side wall surface of the positioning sliding seat 203. The annular guide rail 202 is located at the top of the stabilizing frame 201 to form a fastening connection. The two sides of the bottom end of the stabilizing frame 201 and the top of the slotted flexible metal stacking frame 1 form a fastening connection.

[0029] The frequency modulation control processor 206 detects the vibration source position point generated when the cylinder oil circuit control structure 3 operates according to the vibration source detection sensor, and feeds back the detection data to the frequency modulation control processor 206, so that the frequency modulation control processor 206 sends a control instruction to the frequency modulation control processor 206 to control the operating intensity and frequency of the frequency modulation generator 205.

[0030] A transverse sliding guide rail 9 is installed at the bottom of the slotted flexible metal stacking frame 1.

The magnetostrictive driver 7 is located on the outer peripheral side of the cylinder oil circuit control structure 3 to form a symmetrical installation. The magnetostrictive driver 7 is electrically connected to the PLC controller during mold operation, so that the magnetic field is generated by applying current through the PLC controller, causing the magnetostrictive driver to generate a small deformation in the opposite direction of the cylinder vibration, thereby offsetting the vibration of the cylinder of the cylinder oil circuit control structure 3.

[0032] In a specific solution, the transverse sliding guide rail 9 ensures that the slotted flexible metal stacking rack 1 and its internal structure can be smoothly moved to the predetermined position in the mold installation area, so as to prepare for the subsequent precise docking with the mold. Then, when the mold hot forming operation starts, the vibration source detection sensor monitors the vibration frequency, amplitude and position point information of the oil cylinder oil circuit control structure 3 in real time, and transmits the generated detection data to the frequency modulation control processor 206. At the same time, the magnetostrictive driver 7 is used to make the PLC controller coordinate the operation of the magnetostrictive driver 7 and the active control component 2 according to the preset program by applying currents of different intensities and directions, thereby generating a slight deformation, so that when the oil cylinder is detected to have a tendency to vibrate to the left, the PLC controller controls the magnetostrictive driver 7 to generate a slight deformation to the right on the right side of the oil cylinder to offset part of the vibration. Secondly, after receiving the data from the vibration source detection sensor, the frequency modulation control processor 206 performs analysis and judgment, so that if it is detected that The oil cylinder oil circuit control structure 3 generates 50Hz vibration during frequent telescopic movements. The frequency modulation control processor 206 calculates that the frequency modulation generator 205 should generate an anti-phase wave with a frequency close to 50Hz and appropriate amplitude and phase. Then, the frequency modulation control processor 206 issues a control instruction to the frequency modulation generator 205, so that the frequency modulation generator 205 generates corresponding high-frequency or low-frequency waves according to the instructions to interact with the waves generated by the vibration of the oil cylinder oil circuit control structure 3, so that near the vibration source, the anti-phase wave generated by the frequency modulation generator 205 is superimposed on the oil cylinder vibration wave, so that the vibration amplitude of the synthetic wave is significantly reduced, thereby effectively offsetting part of the vibration energy. In the above process, the positioning sliding seat 203 can be moved on the annular guide rail 202 as needed, and the electrically controlled adjustment arm 204 can adjust the position and angle of the frequency modulation generator 205 to ensure that the anti-phase wave generated by the frequency modulation generator 205 can accurately act on the vibration source area, improve the vibration offset effect, and improve the molding accuracy and quality stability of the mold product.
