Description

Technical Field

[0001] This invention relates to the field of hydraulic drive technology, and more specifically to a hydraulic drive device that can achieve uniform power distribution in a mold. Background Technology

[0002] Hydraulic drive is a driving technology that uses hydraulic oil as a power source to drive mechanical equipment. It features high transmission efficiency, high adjustability, and flexible start and stop, and is widely used in industrial processes. Hydraulic oil is pressed into the piston cylinder, causing the piston to move. At the same time, hydraulic oil is discharged from the other end of the piston, generating hydraulic pressure. When the piston pushes the power component of the mechanical equipment, the mechanical equipment can be driven.

[0003] For example, an in-mold hydraulic drive mechanism for injection molds, with authorization announcement number CN205219628U, includes a mold, a cylinder, a piston rod drive device, and a rear end cover. The cylinder is located inside the mold and is an integral structure with the mold. A slider is provided at the upper end of the cylinder.

[0004] Hydraulic drive devices are used in molds. However, since the driving force of the hydraulic drive device is applied in a certain direction, it is difficult to distribute the power evenly inside the mold. The hydraulic drive device needs to be installed in different parts of the mold. However, due to its structural limitations, the hydraulic drive device is not convenient to be installed in any position, and the power distribution is still not even. Therefore, it is urgent to design a hydraulic drive device that can achieve uniform power distribution in the mold to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a hydraulic drive device that can achieve uniform power distribution in a mold, thereby overcoming the aforementioned shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A hydraulic drive device for uniform power distribution in a mold includes a drive mechanism, a base, an upper mold, and a lower mold. The drive mechanism includes an accumulator, a power cylinder, a base plate, a piston, and a connecting pipe. The accumulator is bolted to the top of the base plate. The power cylinder is bolted to one side of the top of the base plate, and the piston is movably inserted into the inside of the power cylinder. A limiting frame is fixedly installed inside the base. Racks are movably inserted into both sides of the limiting frame, and one end of the rack has an integrally formed insertion plate. An inclined block is welded to one side of the insertion plate. Movable cavities are formed on both sides of the base. A retaining frame is welded to the inner wall of the movable cavity. A base arm is movably connected inside the retaining frame. A rolling wheel is movably connected to one end of the base arm via a bearing. A gear is movably connected to the inner wall of the bottom of the base, and a rotating rod is welded to the top of the gear. A knob is welded to the top of the rotating rod.

[0008] Preferably, a spring is welded to one side of the inside of the knob, and a protrusion is welded to one end of the spring.

[0009] Preferably, an outer cover button is welded to the middle of the top of the substrate, and a through groove is opened on one side of the outer wall of the outer cover button, with a protrusion engaging inside the through groove.

[0010] Preferably, an adhesive pad is bonded to the inner wall of the base arm, and a flow cavity is formed inside the substrate.

[0011] Preferably, one end of the connecting pipe is integrally formed with a connecting pipe, and the interior of the connecting pipe is provided with an anti-corrosion layer.

[0012] Preferably, a protruding part is fitted inside one end of the anti-corrosion layer, and a sealing end is integrally formed on the outside of the protruding part.

[0013] Preferably, the end of the connecting pipe away from the connecting pipe is threadedly connected to a through pipe end, and a flow pipe is inserted into the inner wall of one end of the through pipe end, and the flow pipe is located inside the lower mold.

[0014] Preferably, the drive mechanism is located on the top side of the lower mold, and the top end of the piston is located at the bottom of the upper mold.

[0015] Preferably, the base arm is movably disposed inside the movable cavity, and the outer wall of the gear meshes with one side of the rack.

[0016] Preferably, the bottom of the substrate is bolted to the top of the base, and the rotating rod is inserted inside the substrate.

[0017] In the above technical solution, the present invention provides a hydraulic drive device that can achieve uniform power distribution in a mold. Through the setting of a drive mechanism, a base base, and a base arm, the accumulator of the drive mechanism is used to adjust the wedge power to prevent system overpressure. The drive mechanism is located between the upper and lower molds. By rotating the knob, the plug plate is pushed to both ends. The inclined surface of the inclined block contacts the rolling wheel, which can then snap the drive mechanism into the lower mold and install it in any position through the base arm. The drive mechanism achieves uniform power distribution in the mold. Through the setting of an outer cover button and a protrusion, after the knob is rotated, the protrusion at the end of the spring extends outward and can be locked into the outer cover button, which facilitates the fixation after the knob moves and also prevents the base arm from loosening. The fitting pad inside the base arm can also improve the stability of the drive mechanism. Through the setting of a sealing end and a different protrusion, the sealing end can use the protrusion of the different protrusion to snap into the anti-corrosion layer, which is conducive to the sealing end tightly connecting the connecting pipe and the base plate.

[0029] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-8 As shown in the figure, an embodiment of the present invention provides a hydraulic drive device that can achieve uniform power distribution in a mold, including a drive mechanism, a base 9, an upper mold 7, and a lower mold 8. The drive mechanism includes an accumulator 1, a power cylinder 2, a base plate 3, a piston 4, and a connecting pipe 5. The accumulator 1 is bolted to the top of the base plate 3, and the power cylinder 2 is bolted to one side of the top of the base plate 3, with the piston 4 movably inserted into the interior of the power cylinder 2. A limiting frame 18 is fixedly installed inside the base 9, and both sides of the limiting frame 18 are movably inserted into... A rack 17 is attached, and one end of the rack 17 is integrally formed with a plug plate 13. An inclined block 12 is welded to one side of the plug plate 13. Movable cavities 21 are opened on both sides of the base 9. A locking frame 15 is welded to the inner wall of the movable cavity 21. A base arm 10 is movably connected inside the locking frame 15. A rolling wheel 14 is movably connected to one end of the base arm 10 through a bearing. A gear 19 is movably connected to the inner wall of the bottom of the base 9. A rotating rod 16 is welded to the top of the gear 19. A knob 11 is welded to the top of the rotating rod 16.

[0031] Specifically, in this embodiment, a drive mechanism, a base 9, an upper mold 7, and a lower mold 8 are included. The drive mechanism includes an accumulator 1, a power cylinder 2, a base plate 3, a piston 4, and a connecting pipe 5. The accumulator 1 is bolted to the top of the base plate 3, and the power cylinder 2 is bolted to one side of the top of the base plate 3. The piston 4 is movably inserted into the inside of the power cylinder 2. The accumulator 1 can be used to adjust the power of the wedge device to prevent system overpressure. When the wedge device reaches the stop position, a small amount of oil will flow into the accumulator 1. When the piston 4 on the power cylinder 2 is driven by a press or machine tool, the wedge device will start. The dimensions of the drive mechanism can be calculated from the number, size, and stroke length of the wedge devices in the system. When the system is full of oil, the piston 4 on the power cylinder 2 and the accumulator 1 are at the same height. A limiting frame 18 is fixedly installed inside the base 9. Racks 17 are movably inserted into both sides of the inside of the limiting frame 18, and one end of the rack 17 is integrally formed with a connecting plate 13. An inclined block 12 is welded to one side of the connecting plate 13. Movable cavities 21 are opened on both sides of the base 9. A locking frame 15 is welded to the inner wall of the movable cavity 21. A base arm 10 is movably connected inside the locking frame 15. One end of the base arm 10 is movably connected to a rolling wheel 14 via a bearing. A gear 19 is movably connected to the inner wall of the bottom of the base 9, and a rotating rod 16 is welded to the top of the gear 19. A knob 11 is welded to the top of the rotating rod 16, and the knob 11 can be manually rotated by a person. Then, the bottom of the rotating rod 16 rotates the gear 19, and the rack 17 outside the gear 19 can be pushed, causing the inclined block 12 on the plug plate 13 to be pushed. The inclined block 12 squeezes the rolling roller 14. The rolling roller 14 is supported by the clamping bracket 15, and the base arm 10 at one end of the rolling roller 14 can be pried, while the lower part of the base arm 10 away from the rolling roller 14 can be pressed down. The base arm 10 can be fixed at any position in the lower mold 8, and the drive mechanism can realize power distribution in the mold.

[0032] The present invention provides a hydraulic drive device that can achieve uniform power distribution in a mold. Through the set drive mechanism, base 9 and base arm 10, the accumulator 1 of the drive mechanism is used to adjust the wedge power to prevent system overpressure. The drive mechanism is located between the upper mold 7 and the lower mold 8. By rotating the knob 11, the plug plate 13 is pushed to both ends. The inclined surface of the inclined block 12 contacts the rolling wheel 14, so that the drive mechanism can be snapped into the lower mold 8 and installed in any position through the base arm 10. The drive mechanism achieves uniform power distribution in the mold.

[0033] In one embodiment provided by the present invention, such as Figure 1 and Figure 6 As shown, a spring 29 is welded to one side of the inside of the knob 11, and a protrusion 28 is welded to one end of the spring 29. When the knob 11 is rotated, one end of the spring 29 can cause the protrusion 28 to protrude outward, thus restricting the position of the knob 11.

[0034] In another embodiment provided by the present invention, such as Figure 1 , Figure 5 and Figure 6 As shown, an outer cover button 27 is welded to the middle of the top of the substrate 3. A through groove 30 is provided on one side of the outer wall of the outer cover button 27, and a protrusion 28 is engaged inside the through groove 30. The through groove 30 inside the outer cover button 27 facilitates the latching of the protrusion 28, so that the knob 11 is stably locked in the outer cover button 27. After pressing the protrusion 28, the knob 11 can be rotated.

[0035] In another embodiment provided by the present invention, such as Figure 1 and Figure 6 As shown, an adhesive pad 31 is bonded to the inner wall of the base arm 10. After the base arm 10 is pressed down, the adhesive pad 31 makes the base arm 10 fit tightly against the lower mold 8, thus fixing the drive mechanism. A flow cavity 20 is opened inside the substrate 3, allowing hydraulic oil to pass through.

[0036] In one embodiment provided by the present invention, such as Figure 1 and Figure 7 As shown, one end of the connecting pipe 5 is integrally formed with a connecting pipe 23, and the inside of the connecting pipe 23 is provided with an anti-corrosion layer 26, which can prevent corrosion inside the connecting pipe 23.

[0037] In another embodiment provided by the present invention, such as Figure 1 and Figure 7 As shown, a protruding part 25 is inserted inside one end of the anti-corrosion layer 26, and a sealing end 24 is integrally formed on the outside of the protruding part 25. The protruding part 25 is an irregularly shaped convex structure, and the convex part of the protruding part 25 can be inserted into the anti-corrosion layer 26 to tightly connect the sealing end 24 and the substrate 3.

[0038] In another embodiment provided by the present invention, such as Figure 1 and Figure 7 As shown, the end of the connecting pipe 5 away from the connecting pipe 23 is threadedly connected to the pipe end 22. The inner wall of the pipe end 22 is inserted into the flow pipe 6, and the flow pipe 6 is located inside the lower mold 8. Oil is introduced into the flow pipe 6, and the oil can be input into the pipe end 22 and the connecting pipe 5.

[0039] In one embodiment provided by the present invention, such as Figure 1 and Figure 2 As shown, the drive mechanism is located on the top side of the lower mold 8, and the top of the piston 4 is located at the bottom of the upper mold 7. After the upper mold 7 moves down, it can press against the top of the piston 4, or push the piston 4 out, so that the upper mold 7 moves up.

[0040] In another embodiment provided by the present invention, such as Figure 1 , Figure 4 and Figure 5 As shown, the base arm 10 is movably disposed inside the movable cavity 21. The space of the movable cavity 21 allows the base arm 10 to move downwards. The outer wall of the gear 19 meshes with one side of the rack 17. After the gear 19 rotates, it can push the rack 17.

[0041] In another embodiment provided by the present invention, such as Figure 1 and Figure 5 As shown, the bottom of the substrate 3 is bolted to the top of the base 9, the substrate 3 can be separated from the base 9, and the rotating rod 16 is inserted inside the substrate 3.

[0042] Working principle: Accumulator 1 is used to adjust the wedge power. When piston 4 on power cylinder 2 is driven by a press or machine tool, the wedge device will start. When filled with oil, piston 4 on power cylinder 2 and accumulator 1 are at the same height. The operator places the drive mechanism between upper mold 7 and lower mold 8, with the drive mechanism on lower mold 8. The operator turns knob 11, which drives rotating rod 16 to rotate. The bottom of rotating rod 16 rotates gear 19. The outside of gear 19 can push rack 17 to move, causing rack 17 to drive insert plate 13 to move. Insert plate 13 pushes to both ends, causing tilting block 12 to also move. The tilting surface of tilting block 12 contacts rolling roller 14, causing rolling roller 14 on tilting block 12 to be pressed. The roller 14 is pried up by the clamping bracket 15. After the roller 14 is lifted up, the base arm 10 is pressed down and the base arm 10 is locked onto the lower mold 8, so that the drive mechanism is installed in the designated position. After the knob 11 is rotated, the protrusion 28 on the knob 11 is pushed and extended by the spring 29. The protrusion 28 can be inserted into the inside of the through groove 30, so that the knob 11 is fixed in the outer cover knob 27, preventing the knob 11 from moving arbitrarily. When the person inserts their hand into the through groove 30, the protrusion 28 squeezes the spring 29, so that the knob 11 can rotate freely again. The sealing end 24 is sealed and connected to the base plate 3. The sealing end 24 is locked inside the anti-corrosion layer 26 by the irregular protrusion 25. The protrusion on the outside of the irregular protrusion 25 is fixed to the anti-corrosion layer 26, so that the sealing end 24 is stably connected.

[0043] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
