Description

Technical Field

[0001] This utility model relates to the field of hydraulic press technology, and in particular to a hydraulic press mold enhancement pressing structure. Background Technology

[0002] Hydraulic press mold technology originated from the industrial application of hydraulic transmission principles in the 19th century. With the advancement of materials science and machining in the 20th century, mold manufacturing technology has gradually developed, mainly based on high-strength alloy steel (such as Cr12MoV, H13) and cemented carbide. Combined with modern precision machining (such as CNC, EDM) and heat treatment processes (vacuum quenching, surface nitriding), along with high-precision hydraulic control systems (proportional valves, servo drives) and computer-aided design (CAD / CAE), it has achieved a technological leap from simple stamping to complex precision forming (such as automotive body panels, aerospace components). At the same time, intelligent (pressure / temperature sensing feedback) and modular design have further improved the efficiency and lifespan of the molds.

[0003] Traditional hydraulic press mold pressing structures generally suffer from uneven pressure and insufficient rigidity. During the hydraulic process, they are prone to mold deformation, uneven wear, and thermal deformation, which affect molding accuracy and mold life. Utility Model Content

[0004] In order to overcome the shortcomings of traditional hydraulic press mold pressing structures, which are prone to mold deformation, off-center wear and thermal deformation during hydraulic processes, the technical problem is to provide a hydraulic press mold reinforcing pressing structure.

[0005] The technical solution is as follows: A hydraulic press mold reinforcement pressing structure includes a main hydraulic cylinder, a lifting frame, an auxiliary hydraulic cylinder, a lifting block, an upper module, guide rods, springs, a protective shell, and a controller. The lifting frame is connected to the telescopic rod at the bottom of the main hydraulic cylinder. An auxiliary hydraulic cylinder is installed at the bottom of the upper plate of the lifting frame. The lifting block is connected to the telescopic rod at the bottom of the auxiliary hydraulic cylinder, and the lifting block slides through the lower plate of the lifting frame. The upper module is fixed to the bottom of the lifting block. Two guide rods slide symmetrically through the upper part of the lifting block, and the other end of each guide rod is fixed to the top of the lower plate of the lifting frame. Two springs are symmetrically connected between the top of the lower plate of the lifting frame and the upper part of the lifting block. The four springs are respectively sleeved on the outer walls of the four guide rods. The guide rods restrict the lateral displacement of the lifting block, and the springs provide elastic preload to compensate for the mold parallelism error. A protective shell is fixed to the outer wall of the lower plate of the lifting frame, and a controller is installed on the front side of the protective shell.

[0006] Optionally, it also includes an air pump and an air blowing pipe, with the air pump installed on the rear side of the protective shell and the air blowing pipe connected to the front side of the air pump, and the air blowing pipe passing through the rear side of the protective shell.

[0007] Optionally, it also includes a rubber pad, with the bottom of the protective shell fixed to the rubber pad to reduce friction during contact.

[0008] Optionally, it also includes pressure sensors. Pressure sensors are installed on both the left and right sides of the protective housing to monitor the pressure on the lower module when the upper module contacts the lower module. The controller is electrically connected to the main hydraulic cylinder, auxiliary hydraulic cylinder, air pump and pressure sensors. The pressure sensors feed back signals to the controller to adjust the output pressure of the main hydraulic cylinder and auxiliary hydraulic cylinder in real time.

[0009] Optionally, it also includes a heat dissipation mesh, with heat dissipation holes provided on the left rear and right rear of the protective shell, and heat dissipation mesh provided in each heat dissipation hole.

[0010] Optionally, the upper module is made of hard alloy material with high hardness and wear resistance.

This utility model achieves dynamic and balanced adjustment of pressing pressure by working in tandem with the main hydraulic cylinder and the auxiliary hydraulic cylinder, and with the real-time monitoring and feedback control of the pressure sensor, effectively solving the problem of uneven pressure in traditional structures.

Detailed Implementation

[0019] Example:

[0020] A hydraulic press mold reinforcement pressing structure, such as Figures 1-5 As shown, the system includes a main hydraulic cylinder 1, a lifting frame 2, an auxiliary hydraulic cylinder 3, a lifting block 4, an upper module 41, guide rods 5, springs 6, a protective shell 7, and a controller 9. The bottom telescopic rod of the main hydraulic cylinder 1 is connected to the lifting frame 2. The auxiliary hydraulic cylinder 3 is fixedly installed at the bottom of the upper plate of the lifting frame 2. The bottom telescopic rod of the auxiliary hydraulic cylinder 3 is connected to the lifting block 4, and the lifting block 4 slides through the lower plate of the lifting frame 2. The bottom end of the lifting block 4 is fixedly connected to the upper module 41. Two guide rods 5 are symmetrically slidably inserted through the upper part of the lifting block 4, and the other end of each guide rod 5 is fixedly connected to the lifting frame 2. At the top of the lower plate, there are two springs 6 symmetrically connected between the top of the lower plate of the lifting frame 2 and the upper part of the lifting block 4. The four springs 6 are respectively sleeved on the outer side wall of the four guide rods 5. The guide rods 5 restrict the lateral displacement of the lifting block 4. The springs 6 provide elastic preload to compensate for the parallelism error of the mold. A protective shell 7 is fixedly connected to the outer side wall of the lower plate of the lifting frame 2. A controller 9 is fixedly installed on the front side of the protective shell 7. It also includes a rubber pad 8. The bottom end of the protective shell 7 is fixedly connected to the rubber pad 8 to reduce the friction generated during contact. The upper module 41 is made of hard alloy material with high hardness and strong wear resistance.

[0021] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, it also includes an air pump 11 and an air blowing pipe 12. The air pump 11 is installed on the rear side of the protective shell 7, and the air blowing pipe 12 is connected to the front side of the air pump 11. The air blowing pipe 12 passes through the rear side of the protective shell 7. It also includes a pressure sensor 10. Pressure sensors 10 are fixedly installed on the left and right sides of the protective shell 7 to monitor the pressure on the lower module when the upper module 41 contacts the lower module. The controller 9 is electrically connected to the main hydraulic cylinder 1, the auxiliary hydraulic cylinder 3, the air pump 11 and the pressure sensor 10. The pressure sensor 10 feeds the signal back to the controller 9 to adjust the output pressure of the main hydraulic cylinder 1 and the auxiliary hydraulic cylinder 3 in real time. It also includes a heat dissipation mesh 13. Heat dissipation holes are opened on the rear left and rear right sides of the protective shell 7, and heat dissipation mesh 13 is installed in each heat dissipation hole.

[0022] When using this device, first suspend the device above the lower module. Then, the controller 9 activates the main hydraulic cylinder 1, whose telescopic rod pushes the lifting frame 2 and protective shell 7 downwards as a whole. When the protective shell 7 brings the rubber pad 8 into contact with the lower module, the auxiliary hydraulic cylinder 3 installed at the bottom of the upper plate of the lifting frame 2 is activated to work synchronously. The auxiliary hydraulic cylinder 3 drives the lifting block 4 to slide precisely along the guide rod 5 through the telescopic rod. The guide rod 5, with its symmetrical layout, effectively limits the lateral displacement of the lifting block 4, ensuring the straightness of the movement trajectory. The spring 6 sleeved on the outside of the guide rod 5 provides elastic preload, dynamically compensating for the parallelism error generated when the mold contacts the workpiece. When the upper module 41 contacts the workpiece, the lower module is subjected to the downward pressure of the workpiece, protecting the lower module. Pressure sensors 10 on both sides of the shell 7 monitor the pressing pressure on the lower module in real time and feed the data back to the controller 9. The user can adjust the output pressure of the main hydraulic cylinder 1 and the auxiliary hydraulic cylinder 3 through the controller 9 to achieve a balanced pressure distribution. During this process, the air pump 11 on the rear side of the protective shell 7 sprays cooling airflow through the air pipe 12 to cool the upper module 41 and prevent the module 41 from overheating and deforming. The rubber pad 8 set at the bottom of the protective shell 7 can buffer the contact impact, reduce vibration noise and reduce friction. The heat dissipation mesh 13 on the left and right rear of the protective shell 7 works with the air pump 11 and the air pipe 12 to achieve the heat dissipation effect. At the same time, the upper module 41 is made of hard alloy material to enhance heat resistance. Thus, the entire process of enhanced pressing is completed.
