Description

Technical Field

[0001] The present invention relates to the technical field of casting devices, and particularly to an intelligent casting device for a hydraulic actuator housing. Background Art

[0002] A hydraulic actuator is a mechanism that converts hydraulic energy into mechanical energy or other forms of energy. After pressurizing hydraulic oil by a hydraulic pump, it is delivered to a hydraulic cylinder. The plunger in the hydraulic cylinder generates linear motion under the pressure of the hydraulic oil, thereby realizing the motion of mechanical equipment. Hydraulic actuators are widely used in fields such as machinery, industry, agriculture, and aviation, such as in equipment like hydraulic shearing machines, hydraulic presses, machine tools, cranes, tractors, etc.

[0003] Currently, the housing part of a hydraulic actuator is often cast by die-casting. First, a suitable alloy material, such as aluminum alloy, is selected and melted; the melted alloy liquid is poured into a pressure chamber, and then filled into the cavity of a steel mold at high speed. Under high pressure, the alloy liquid solidifies to form a housing casting with a predetermined shape and size; secondly, after the casting is completely cooled and solidified in the mold, the mold is opened to take out the housing casting.

[0004] When the existing casting device takes out the hydraulic actuator housing, since the casting is still in a high-temperature state and cannot be directly touched and taken out, a pick rod is generally used to directly insert into the inner cavity of the housing and pick it up to take it out. However, for the above-mentioned picking method, on the one hand, the stability of the casting is poor. The hydraulic actuator housing casting has multiple through holes, and it is very difficult to control the balance of the housing during the operation. After the pick rod shakes, it is easy to slide along the pick rod and injure or scald the operator, or may directly fall off the pick rod. The falling and bumping not only cause the housing to deform, but if it hits the lower mold, it will cause the mold to be damaged or deformed, thus affecting subsequent production and use; on the other hand, the pick rod is in point contact with the inner wall of the housing cavity, with a small force-bearing area, and the shaking when picking up the housing causes the contact point to slip. The characteristics of the die-casting process are that the die-cast parts usually have high dimensional accuracy and surface quality, and the slip of the contact point will reduce the surface accuracy of the inner wall of the casting.

[0005] Therefore, it is urgent to improve the taking-out method of the existing casting device to improve stability and safety. Based on the above situation, the present invention proposes an intelligent casting device for a hydraulic actuator housing with a stable taking-out function. Summary of the Invention

Detailed implementation manners

[0024] The following further describes the present invention in conjunction with the appended Figures 1-9 drawings and embodiments.

[0025] An intelligent casting device for a hydraulic actuator housing, referring to the appended Figure 1, including a die-casting machine 1, on which there are symmetrically distributed pressing components 2 connected in a sliding manner. A first multi-section electric push rod 3 is installed on the die-casting machine 1. The output end on the upper side of the first multi-section electric push rod 3 is fixedly connected to an upper die component 4, and the upper die component 4 is connected to the die-casting machine 1 in a sliding manner. The upper die component 4 performs a lifting action under the output control of the first multi-section electric push rod 3. An electric ejector pin is provided on the upper die component 4. The upper die component 4 is used to clamp the cast housing body 5. Controlling the electric ejector pin on the upper die component 4 can separate the housing body 5 from the upper die component 4. This technology is an existing technology and will not be elaborated in detail in this embodiment.

[0026] Reference appendix Figures 2-3 , on both sides of the die-casting machine 1, there is a movable frame 6 connected in a sliding manner. An inner support mechanism is installed on the upper side of the movable frame 6 to position the housing body 5 at the picking height by acting on the inner wall of the inner cavity of the housing body 5.

[0027] Specifically, the inner support mechanism includes a second multi-section electric push rod 7 provided on the movable frame 6. The output end of the second multi-section electric push rod 7 is connected to a follower ring 8, and the follower ring 8 moves with the output end of the second multi-section electric push rod 7. Three concentric positioning rods 9 are fixedly connected to the follower ring 8 and are evenly distributed along the circumference. The concentric positioning rod 9 includes a limiting part 901 fixedly connected to the follower ring 8 and a guiding rod 902 connected to the limiting part 901 and parallel to the axis of the follower ring 8. A resisting part 10 is provided radially outward of the follower ring 8. The guiding rod 902 penetrates through the resisting part 10, and a limiting cap 904 is connected to the end. A telescopic spring 903 sleeved outside the guiding rod 902 is provided between the limiting cap 904 and the resisting part 10, and the telescopic spring 903 is always in a compressed state.

[0028] In the initial state, the elastic force generated by the compressed state of the telescopic spring 903 presses the resisting part 10 against the limiting part 901 of the concentric positioning rod 9. That is, before entering the inner cavity of the housing body 5, the resisting part 10 is concentrically sleeved outside the follower ring 8 and its position is determined. The function of the concentric positioning rod 9 is, on the one hand, when the follower ring 8 moves and is misaligned with the resisting part 10, it can support the resisting part 10 to maintain its coaxiality with the axis of the follower ring 8; on the other hand, it is used to sleeve the telescopic spring 903 to determine the relative position relationship between the resisting part 10 and the follower ring 8.

[0029] One side of the follower ring 8 is also fixedly connected with connecting rods 11 evenly distributed circumferentially. The end of the connecting rod 11 is rotatably connected with a rotating rod 12. A guide frame 13 is fixedly connected to the resisting member 10. Along its radial direction, the guide frame 13 is fixedly connected with sliding columns (not shown) evenly distributed circumferentially. A squeezing member 14 is sleeved outside the sliding column and is slidably connected. A rotating cylinder 15 is rotatably connected to the squeezing member 14. A cavity is provided inside the rotating cylinder 15. The end of the rotating rod 12 is placed inside the cavity of the rotating cylinder 15, that is, the rotating cylinder 15 is slidably connected with the rotating rod 12.

[0030] A closing spring 16 is connected between the rotating cylinder 15 and the rotating rod 12. Its function is that before the inner support mechanism enters the inner cavity of the housing body 5, the contraction elastic force generated by its stretched state makes the squeezing member 14 in the state closest to the guide frame 13. At this time, the total length of the rotating cylinder 15 and the rotating rod 12 is the shortest, that is, at this time the inner support mechanism is in a closed state, so that it can be pushed into the inner cavity of the housing body 5 without colliding with it.

[0031] An inner support spring 17 is also provided in the inner cavity of the rotating cylinder 15. The inner support spring 17 is sealed in the inner cavity of the rotating cylinder 15 by the rotating rod 12 with its end placed inside the rotating cylinder 15. When the rotating cylinder 15 and the rotating rod 12 slide relative to each other, the length of the inner support spring 17 changes with the total length of the rotating cylinder 15 and the rotating rod 12. The function of the inner support spring 17 is that when it is compressed, the elastic force generated presses the squeezing member 14 tightly against the inner wall of the inner cavity of the housing body 5. The inner cavity of the rotating cylinder 15 is communicated with the outside through an air port, or there is a gap between the sliding mating surfaces of the rotating cylinder 15 and the rotating rod 12, aiming to make the inner cavity of the rotating cylinder 15 communicate with the outside and ensure the smoothness of the relative sliding between the rotating cylinder 15 and the rotating rod 12. This is a conventional technical means and will not be elaborated.

[0032] The principle of positioning the housing body 5 at the picking height through the action of the inner support mechanism on the inner wall of the inner cavity of the housing body 5 is as follows: When the housing body 5 is lifted to the picking height by the first multi-stage electric push rod 3, the interface surfaces on its left and right sides are aligned with the guide frame 13, and the first multi-stage electric push rod 3 pauses operation, and the housing body 5 no longer moves upward. At this time, control the second multi-stage electric push rod 7 to drive the inner support mechanism to move inward. The inner support mechanism is in a closed state under the action of the closing spring 16. At this time, the inner support mechanism can enter the housing body 5 along the interface. When the moving stop member 10 contacts the outer wall of the housing body 5, the side wall of the housing body 5 will abut against the stop member 10 to stop it, and then the guide frame 13 connected thereto remains stationary in the inner cavity of the housing body 5. Thereafter, the follower ring 8 travels with the second multi-stage electric push rod 7, so that the guide rod 902 of the concentric positioning rod 9 slides relative to the stop member 10, compressing the telescopic spring 903 thereon. The follower ring 8 enters the inner cavity of the housing body 5 and is misaligned with the stop member 10; at the same time, the follower ring 8 drives the connecting rod 11 to continue to move inward, the distance between the connecting rod 11 and the guide frame 13 is shortened, and the rotating rod 12 rotates relative to the connecting rod 11. The closing spring 16 in the stretched state before has a smaller amount of stretching deformation, and the rotating rod 12 will drive the rotating cylinder 15 sleeved thereon to rotate, and the closed inner support mechanism begins to expand, thereby driving the pressing member 14 to slide outward in the radial direction of the guide frame 13 until the pressing member 14 contacts the inner wall of the housing body 5. When the pressing member 14 contacts the inner wall of the housing body 5, as the connecting rod 11 continues to move inward, the total length of the rotating cylinder 15 and the rotating rod 12 becomes shorter, and the rotating rod 12 further slides into the inner cavity of the rotating cylinder 15, thereby compressing the inner support spring 17 in the inner cavity of the rotating cylinder 15, and the closing spring 16 further contracts. At this time, the elastic force of the inner support spring 17 causes the pressing member 14 to tightly press against the inner wall of the housing body 5, that is, the housing body 5 is fixed from the inside by the pressing member 14.

[0033] In this embodiment, by controlling the second multi-stage electric push rod 7, the deformation degree of the inner support spring 17 can be controlled, and thus it is ensured that the pressure of the pressing member 14 tightly pressing against the inner wall of the housing body 5 is appropriate. This fixing method is not only stable and reliable, but also can adapt to housing bodies 5 of different sizes, because by adjusting the lengths of the rotating rod 12 and the rotating cylinder 15 and the elastic moduli of the closing spring 16 and the inner support spring 17, effective fixing of housing bodies of different sizes can be achieved.

[0034] Before the internal support mechanism positions the housing body 5 at the removal height, the first multi-section electric push rod 3 must be used to lift the housing body 5 to the removal height. Conventional technology uses control of the electric ejector pin on the upper die member 4 to achieve engagement and disengagement with the housing body 5. However, in actual production processes, the engagement strength of the electric ejector pin with the housing body 5 is sufficient during the material removal and rise period. However, in this embodiment, based on the premise that the housing body 5 must be positioned by the internal support mechanism, the left and right interface surfaces of the housing body 5 must be strictly aligned with the guide frame 13 when the internal support mechanism enters the housing body 5, and the internal support mechanism must be in a closed position. This control is not reliable, especially when the die-casting machine 1 is operating at high temperatures. In this embodiment, the springs will creep, posing a risk of failure. Once the internal support mechanism enters the housing body 5 in an open position, it will directly impact the housing body 5, causing it to dislocate and fall. This embodiment provides redundant positioning of the housing body 5 by providing an anti-drop mechanism. If the housing body 5 dislocates, it will still be supported by the anti-drop mechanism.

[0035] Reference Attachment Figures 4-6 The anti-fall mechanism is provided on the upper mold member 4 and includes a fixing frame 18, which is fixed to the upper mold member 4. A flip plate 19 is rotatably connected to both sides of the fixing frame 18. The flip plate 19 is also slidably connected to an anti-fall rod 20 that fits into the interface of the housing body 5. When the housing body 5 is pulled up, the flip plate 19 rotates in a controlled manner, and the anti-fall rod 20 on it fits into the interface of the housing body 5. When the housing body 5 is dislocated, it is immediately received by the anti-fall rod 20.

[0036] The flip plate 19 realizes the linkage opening and closing operation through the mechanical structure provided on the upper mold part 4. The upper mold part 4 is slidably connected to a sliding frame 21, and racks 22 are fixed on both sides of the sliding frame 21. The pivotal connection between the flip plate 19 and the fixed frame 18 is connected with a torsion spring 23. A gear 24 is fixed on one side of the flip plate 19, and the rack 22 is engaged with the gear 24. The lower side of the sliding frame 21 is slidably connected to a fixing pin 25, and a locking piece 26 is fixed to the upper mold part 4. The lower end of the fixing pin 25 is provided with a slope, and a U-shaped bayonet is opened on the top wall of the locking piece 26. A storage spring 27 is connected between the fixing pin 25 and the sliding frame 21, and the upper side of the sliding frame 21 is slidably connected to a latch 28. A pressure spring 29 is connected between the latch 28 and the sliding frame 21, and the pressure spring 29 is wound around the latch 28. A fixing plate 30 is fixed to the telescopic end of the second multi-section electric push rod 7, and an extrusion frame 31 is also fixed to the die-casting machine 1. The lower side of the latch 28 is provided with a slope, and the lower side of the extrusion frame 31 is also provided with a slope. The extrusion frame 31 is squeezed and matched with the latch 28, the locking piece 26 is squeezed and matched with the fixing pin 25, and the fixing plate 30 is also squeezed and matched with the fixing pin 25.

[0037] After the actuator housing is cooled in the mold, the pressing part 2 is controlled to drive the mold to separate outward, and then the first multi-section electric push rod 3 is controlled to drive the upper mold part 4 to move upward, thereby driving the shell body 5 to move upward, and then driving the flip plate 19, the sliding frame 21, the fixed pin 25, the latch 28, etc. to move upward together. When the upward-moving latch 28 contacts the lower inclined surface of the extrusion frame 31, the inclined surface of the extrusion frame 31 will resist the latch 28 to drive the sliding frame 21 to slide laterally, thereby driving the rack 22 and the fixed pin 25 to move laterally. Since the rack 22 is engaged with the gear 24, the gear 24 drives the flip plate 19 and the anti-fall rod 20 to flip downward, and the torsion spring 23 is twisted, and the anti-fall rod 20 on the flip plate 19 extends to the interfaces on both sides of the shell body 5 without collision. When the laterally moving fixing pin 25 contacts the rear wall of the locking member 26, the wall of the locking member 26 will press against the inclined surface of the fixing pin 25. As the fixing pin 25 continues to move forward, the fixing pin 25 will slide upward, and the force storage spring 27 will be deformed. When the fixing pin 25 passes over the rear wall of the locking member 26, under the elastic force of the force storage spring 27, the fixing pin 25 will be inserted into the U-shaped slot of the locking member 26, so that the flip plate 19 remains in a state of clamping the shell body 5. At this time, the fixing pin 25 is opposite to the fixing plate 30, that is, they are on the same straight line in the direction of travel of the inner support mechanism.

[0038] When the inner support mechanism moves toward the shell body 5, the moving fixed plate 30 first contacts the fixed pin 25. At this time, it indicates that the inner support mechanism can enter the shell body 5 without damage. The fixed plate 30 will support the fixed pin 25 to make it slide upward, forcing the fixed pin 25 to withdraw from the U-shaped bayonet, and the force storage spring 27 will stretch and deform again. At the same time, under the action of the torsion spring 23, the flip plate 19 will drive the anti-fall rod 20 to flip upward and reset, and no longer provide anti-fall protection for the shell body 5. At the same time, the flip plate 19 flips and resets, and drives the sliding frame 21 and the fixed pin 25 to move and reset through the rack 22. When the reset fixed pin 25 separates from the fixed plate 30, under the elastic force of the force storage spring 27, the fixed pin 25 moves downward and resets.

[0039] When the internal support mechanism completes the positioning of the shell body 5, the electric ejector on the upper mold part 4 can be controlled to extend and retract first, and the electric ejector can separate the shell body 5 from the upper mold part 4. Secondly, the first multi-section electric push rod 3 is controlled to drive the upper mold part 4 to move upward away from the shell body 5, and then the movable frame 6 is pulled sideways, thereby driving the shell body 5 to move through the internal support mechanism. The staff can place a table for receiving the die-cast shell body 5 on the side of the die-casting machine 1. Under the action of the shell body 5's own gravity, the staff can operate and control the shell body 5 to make it fall steadily onto the table.

[0040] Reference Attachment Figures 7-9, further comprising a feeding mechanism, the feeding mechanism includes a pushing frame 32, the pushing frame 32 is fixedly connected to the upper die member 4, the lower part of the pushing frame 32 is rotatably connected with a runner 33, a guiding frame 34 is fixedly connected to the moving frame 6, an inclined chute is arranged on the guiding frame 34, and the runner 33 slides in the chute of the guiding frame 34.

[0041] After the inner support mechanism completes the clamping of the housing body 5, the electric ejector pin on the upper die member 4 is disengaged from the housing body 5. Thereafter, the first multi-section electric push rod 3 continues to drive the upper die member 4 to move upward. The moving upper die member 4 will drive the pushing frame 32 and the runner 33 to move upward together. Since the guiding frame 34 is provided with an inclined chute, as the runner 33 moves upward, the runner 33 pushes the moving frame 6 to move through the action of the inclined chute of the guiding frame 34 until the inner support mechanism brings the housing body 5 above the tabletop. The feeding mechanism brings the housing body 5 above the tabletop relying on the output of the first multi-section electric push rod 3 and is realized through the linkage of the mechanical structure without adding a power source, and the realization method is stable and reliable.

[0042] Refer to the appendix Figure 7 and 9 , a positioning component is arranged between the moving frames 6 to enable the removed housing body 5 to accurately stop directly above the tabletop. The positioning component includes a trigger rod 35, the trigger rod 35 is rotatably connected between the moving frames 6, a fixed block 36 is fixedly connected to the moving frame 6, a trigger button 37 is installed on the fixed block 36, the trigger button 37 is electrically connected to the first multi-section electric push rod 3 and the two second multi-section electric push rods 7, a stop projection 38 is connected to the moving frame 6, and the trigger rod 35 rests on the stop projection 38 in its own weight state.

[0043] During the process of the inner support mechanism bringing the housing body 5 above the table, the positioning component moves with the moving frame 6. When the trigger rod 35 contacts a certain part of the placed table, the table will resist the trigger rod 35. As the moving frame 6 continues to move forward, the trigger rod 35 will be flipped to contact the trigger button 37. At this time, the trigger button 37 will control the first multi-section electric push rod 3 to pause operation. At this time, the housing body 5 is above the table and the bottom is close to the table. Thereafter, the second multi-section electric push rod 7 drives the inner support mechanism to close and move outwards, so that the housing body 5 gently lands on the table. The second multi-section electric push rod 7 drives the extrusion member 14 to withdraw from the housing body 5. When the inner support mechanism withdraws from the housing body 5, due to the bearing of the table, the relative position between the inner support mechanism and the housing body 5 remains unchanged and will not collide with the housing body 5, completing the release of the housing. When the moving frame 6 resets and drives the trigger rod 35 to move away from the table, the trigger rod 35 flips under its own gravity and separates from the trigger button 37, and returns to rest on the stop projection 38. The moving frame 6 also returns to its original position, preparing for the processing of the next housing. Through the mutual cooperation of the pushing frame 32, the guiding frame 34, the trigger rod 35, the trigger button 37, etc., precise positioning and release can be achieved when the housing is moved above the table, and it is prepared for the processing of the next housing, improving production efficiency, reducing manual intervention, and reducing labor intensity.

[0044] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
