Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic press mold replacement, and in particular to a convenient and quick-installation mechanism for hydraulic press upper mold. Background Technology

[0002] A hydraulic press (also known as an oil press) is a machine that uses the static pressure of a liquid to process products made of metal, plastic, rubber, wood, powder, etc. It is commonly used in pressing and forming processes such as forging, stamping, cold extrusion, straightening, bending, flanging, sheet metal drawing, powder metallurgy, and press fitting. Traditional hydraulic presses use bolts to fix the upper die, requiring multiple people to assemble and disassemble, and the die positioning accuracy depends on manual adjustment, leading to recurring positioning errors. To address these issues, we have introduced a convenient and quick-assembly mechanism for the upper die of hydraulic presses. Utility Model Content

[0003] This utility model discloses a convenient and quick-installation mechanism for the upper mold of a hydraulic press, which aims to solve the technical problems of traditional hydraulic press upper molds being fixed with bolts, requiring multiple people to cooperate in disassembly and assembly, and the mold positioning accuracy relying on manual adjustment, resulting in repeated positioning errors.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A convenient and quick-assembly mechanism for the upper mold of a hydraulic press includes a hydraulic drive device, a support device, a hydraulic plate, an upper mold, a quick-assembly assembly, and auxiliary components. The support device is composed of a base plate, support rods, and a top plate. The hydraulic drive device is fixed to the top of the top plate. The upper mold is connected to the top of the base plate via the quick-assembly assembly. An auxiliary component is provided between the top of the base plate and the upper mold. The quick-assembly assembly includes connecting blocks, which are fixedly installed on both sides of the bottom of the upper mold. Connecting grooves are provided on the top of the base plate near the corresponding connecting blocks. Fixing plates are symmetrically fixedly installed on both sides of the base plate. Hydraulic cylinders are symmetrically fixedly installed on the top of the fixing plates. Moving grooves are provided inside the base plate near the corresponding hydraulic cylinders. The output end of the hydraulic cylinder extends into the moving groove and is fixedly installed with a moving block. A connecting rod is fixedly installed on the side of the moving block near the corresponding connecting groove. A connecting groove is provided inside the connecting block, and the connecting rod extends into the corresponding connecting groove.

[0006] In use, by setting up a quick-installation component, the connecting block is extended into the corresponding connecting groove. Pressing down on the upper mold causes the connecting block to extend completely into the corresponding connecting groove. Then, by driving the corresponding hydraulic cylinder, the output end of the hydraulic cylinder pushes the moving block to drive the insertion rod to extend into the insertion groove, quickly locking and fixing it. The auxiliary component facilitates the positioning of the upper mold during installation, making installation more convenient. This solves the technical problems of traditional hydraulic presses where the upper mold is fixed with bolts, requiring multiple people to cooperate in disassembly and assembly, and the mold positioning accuracy depends on manual adjustment, resulting in repeated positioning errors.

[0007] In a preferred embodiment, the auxiliary component includes a slide groove. The slide groove is formed in the middle of the top of the base plate. A pressure seat is connected to the inside of the slide groove through a damping rod. Disc springs are fitted on the outer sides of the damping rod. The two ends of the disc springs are fixedly connected to the bottom of the pressure seat and the slide groove, respectively. A positioning pin is fixedly installed in the middle of the top of the pressure seat. A positioning hole is formed on the side of the upper mold near the positioning pin. A sealing ring is fixedly installed on the top of the pressure seat and outside the positioning pin. A sealing groove is formed on the side of the upper mold near the sealing ring. The sealing ring extends into the sealing groove.

[0008] By setting auxiliary components, when the locking and fixing of the upper mold to the quick-installation component is removed, the damping rod and disc spring can push the pressure seat upward, thereby lifting the upper mold, making mold removal more convenient. The disc spring extends into the positioning hole and the sealing ring extends into the sealing groove, making the installation more secure.

[0009] In a preferred embodiment, the output end of the hydraulic drive device extends through to below the top plate and is fixedly mounted with a flange, which is connected and fixed to the hydraulic plate by a fixing bolt.

[0010] Setting up flanges and fixing bolts helps to enhance the stability of the connection between the output end of the hydraulic drive device and the hydraulic plate.

[0011] In a preferred embodiment, the support rod passes through the hydraulic plate and is slidably connected to the hydraulic plate.

[0012] By setting a support rod that passes through the hydraulic plate and slides with it, the stability of the hydraulic plate's up-and-down movement is enhanced.

[0013] In a preferred embodiment, the pressure-bearing seat is configured as a hemispherical structure.

[0014] By setting the pressure seat as a hemispherical structure, the spherical surface can adaptively deflect.

[0015] In a preferred embodiment, a control panel is fixedly mounted on the surface of the base plate, and the hydraulic drive device and the oil cylinder are both electrically connected to the control panel.

[0016] The control panel makes operation more convenient and easier, and a hydraulic drive system is also installed next to the hydraulic drive device and support device.

[0017] The convenient and quick-assembly mechanism for the upper mold of the hydraulic press provided by this utility model has the following advantages:

[0018] This utility model, in use, extends the connecting block into the corresponding connecting groove by setting a quick-installation component. Pressing the upper mold downwards causes the connecting block to fully extend into the corresponding connecting groove. Then, by driving the corresponding hydraulic cylinder, the output end of the hydraulic cylinder pushes the moving block to drive the insertion rod to extend into the insertion groove, quickly locking and fixing it. The auxiliary component facilitates the positioning of the upper mold during installation, making installation more convenient. It solves the technical problems of traditional hydraulic presses where the upper mold is fixed with bolts, requiring multiple people to cooperate in disassembly and assembly, and the mold positioning accuracy depends on manual adjustment, resulting in repeated positioning errors.

The top of the base plate 21 is connected to the upper mold 4 via the quick-assembly assembly 5. The auxiliary assembly 6 is provided between the top of the base plate 21 and the upper mold 4. The quick-assembly assembly 5 includes connecting blocks 51, which are fixedly installed on both sides of the bottom of the upper mold 4 and on the top of the base plate 21. Each corresponding connecting block 51 is provided with a connecting groove 52. A fixing plate 53 is symmetrically fixedly installed on both sides of the base plate 21. A hydraulic cylinder 54 is symmetrically fixedly installed on the top of each fixing plate 53.
