[0002] A hydraulic press (a type of hydraulic press) is a machine that uses special hydraulic oil as the working medium and a hydraulic pump as the power source. The hydraulic oil enters the cylinder / piston through the hydraulic pipeline by the force of the pump. Then there are several sets of seals that cooperate with each other in the cylinder / piston. The seals in different positions are different, but they all play a sealing role to prevent the hydraulic oil from leaking. Finally, the hydraulic oil circulates in the oil tank through a one-way valve to make the cylinder / piston circulate and work, thereby completing a certain mechanical action as a kind of machine for productivity. However, the hydraulic press cannot be used alone as a complete production equipment, but needs to be used in conjunction with other equipment. When the hydraulic press needs to be pressed, it needs to be used with the mold. By adding materials to the mold, and then compacting it through the hydraulic press, the product is obtained.

DETAILED DESCRIPTION

[0019] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 5As shown, the utility model proposes a hydraulic press mold changing structure, the main body of the device is a hydraulic press body 1, and a mold 6 thereon, wherein a movable groove 2 is opened on the hydraulic press body 1, a movable base 3 is arranged inside the movable groove 2, and the mold 6 is arranged on the movable base 3. At the same time, a protrusion 7 is arranged at the front end of the movable base 3, and the protrusion 7 and the hydraulic press body 1 are connected to each other by a buckle structure 8. Therefore, when it is necessary to change the mold, the buckle structure 8 can be adjusted to release the limit of the hydraulic press body 1 and the movable base 3 with the protrusion 7. At this time, the mold 6 can be taken out by controlling the movement of the movable base 3. In order to ensure that when the movable base 3 is separated from the hydraulic press body 1, the mold 6 will not be difficult to move due to the increased friction caused by its own part contacting the hydraulic press body 1, the utility model has cylinder grooves 4 on the front and rear parts of the top of the movable base 3 and the middle parts of both sides, and a telescopic cylinder 5 is arranged in the cylinder groove 4. Therefore, when it is necessary to move, the telescopic cylinder 5 is controlled to lift, so that the mold 6 can be slightly lifted and has a certain distance from the hydraulic press body 1.

[0022] Next, a die-changing platform 9 is provided at the front end of the hydraulic press body 1. The top of the die-changing platform 9 is flush with the bottom wall of the movable base 3, which ensures that it will not block the movement of the movable base 3 when changing the die. The bottom sides and the front and rear parts of the die-changing platform 9 are fixedly connected with legs 26. The bottom ends of the legs 26 are threadedly connected with threaded parts 27, and the bottom ends of the threaded parts 27 are fixedly connected with support parts 28. Under normal conditions, the support parts 28 are universal wheels. If the on-site environment allows the die-changing platform 9 to be docked for a long time, the support parts 28 can be replaced with support components that are easily purchased on the market for fixing.

[0023] Both sides of the top of the mold changing table 9 are fixedly connected with slide rails 10, and the front and rear parts of the top of the slide rails 10 are fixedly connected with fixed blocks 11, and a screw rod 12 is rotatably connected between the front and rear end fixed blocks 11, and a threaded block 13 is threadedly connected to the screw rod 12, and the threaded block 13 is slidably connected to the slide rail 10, and a central axis 14 is fixedly connected between the threaded blocks 13 on both sides, and a mechanical clamp 15 is fixedly connected to the middle of the central axis 14. The mechanical clamp 15 is a prior art and is used to clamp the protrusion 7. Telescopic cylinders 16 are provided on both sides of the protrusion 7, and the separated sides of the telescopic cylinders 16 on both sides are fixedly connected with cylinder seat plates 17, and the cylinder seat plates 17 are fixedly connected to the central axis 14. Therefore, when it is necessary to change the mold of the hydraulic press, the operator can first control the extension of the telescopic cylinder 16 to squeeze the buckle structure 8, and wait until the hydraulic press body 1 and the movable base 3 are released from the limit. At this time, the mechanical clamp 15 clamps the protrusion 7 and rotates the screw rod 12 at the same time, so that the threaded block 13 can move on the screw rod 12, thereby driving the central axis 14 and the mechanical clamp 15 to move, thereby driving the movable base 3 to move, and achieving the result of mold change.

[0024] In order to drive the screw rod 12 to move, the utility model is also provided with a motor 29 at the front end of the screw rod 12, and the output shaft of the motor 29 is fixedly connected to the screw rod 12. A control console 30 is provided at the front end of the top of the mold changing table 9, and motor slots 31 are provided at both ends of the control console 30, and the motor 29 is fixedly connected in the motor slots 31. Therefore, the movement of the screw rod 12 can be controlled by the energization drive of the motor 29, and the control console 30 is used to dispatch the above-mentioned components, which has a control circuit board and is electrically connected to the motor 29, the mechanical gripper 15, the telescopic cylinder 2 16 and the telescopic cylinder 1 5 for control. Since the above-mentioned control circuit board also belongs to the existing structure and is also a technology well known to ordinary technicians in this field, its technical principle will not be repeated here.

[0025] In order to further explain the specific working principle of the utility model, the above-mentioned buckle structure 8 includes a cavity 18 opened in the protruding part 7 and extending to the movable base 3. A fixing column 19 is fixedly connected in the cavity 18. Both ends of the fixing column 19 are slidably connected to a slider 20. The front and rear ends of the slider 20 are respectively fixedly connected to a pressure rod 21 and a latch 22. The pressure rod 21 and the latch 22 pass through the cavity 18 and extend to the outside of the protruding part 7. A groove 23 for matching with the latch 22 is opened on the part of the hydraulic press body 1 located in the movable groove 2. The proximal sides of the latches 22 on both sides are fixedly connected to springs 24. The end of the spring 24 away from the latch 22 is fixedly connected to a fixing seat 25. The fixing seat 25 is fixedly connected to the bottom wall of the cavity 18.

[0026] Therefore, when the telescopic cylinder 16 is extended, the pressure rod 21 can be compressed. After compression, the slider 20 is forced to slide on the fixed column 19, driving the latch 22 to move, squeezing the spring 24 while also bringing the latch 22 away from the groove 23, until it is completely out of the groove 23, and the movable base 3 is released from the hydraulic press body 1.

[0027] It should be specially noted here that the components described and identified in the text and drawings of the utility model are the key components constituting the utility model, and the remaining non-key components or obvious prior art components, such as screws, nuts and other connectors, and technical features similar to the prior art are not shown. However, this does not mean that the above-mentioned components do not exist in the utility model, nor can it be interpreted as a practical limitation on the utility model.

[0028] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
