Description

Technical Field

[0001] This invention relates to the field of mold drive technology, and in particular to an integrated drive device for mold cylinders and slider seats. Background Technology

[0002] In injection molds and die-casting molds, a hydraulic cylinder is typically used to drive a slide block to reciprocate on the mold base to achieve demolding and repositioning of laterally formed parts. In traditional mold drive devices, the hydraulic cylinder is usually a separate power component, fixed to the mold base by an additional mounting plate and bolt assembly, and then connected to the slide block via a connector. However, it is worth considering that the cylinder, connector, and slide block are three independent components that need to be machined separately before assembly. Their axial and radial dimensions are relatively large, often resulting in insufficient space for compact molds or deep-cavity molds.

[0003] Therefore, in order to solve the above problems, a more suitable facility that meets the needs of users is needed. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide an integrated drive device for a mold cylinder and a slider seat, so as to solve the problem that there is often not enough space for compact molds or deep cavity molds.

[0005] To achieve the above objectives, the present invention provides an integrated drive device for a mold cylinder and a slider seat, including a slider seat and a cover plate detachably mounted on the outer wall of the slider seat. A first hydraulic oil chamber is provided on the side of the slider seat facing the cover plate. A first piston is slidably disposed in the first hydraulic oil chamber. A first piston rod is fixedly connected to the side of the first piston facing the cover plate, and the first piston rod passes through the cover plate.

[0006] A second hydraulic oil chamber is provided on the side of the first piston rod facing the first piston. A second piston is slidably disposed in the second hydraulic oil chamber. A second piston rod is fixedly connected to the side of the second piston away from the first piston, and the end of the second piston rod away from the first piston passes through the first piston rod.

[0007] The slider seat is equipped with a main hydraulic circuit assembly. The first hydraulic oil chamber is divided into a rodless chamber and a rod chamber by the first piston. The main hydraulic circuit assembly is used to supply and return oil to the rodless chamber and the rod chamber separated by the first piston. The first piston and the first piston rod are equipped with a secondary hydraulic circuit assembly, which is used to supply and return oil to both sides of the second hydraulic oil chamber separated by the second piston. The slider seat is equipped with a positioning structure for fixing the first piston in a preset position.

[0008] Optionally, the main hydraulic circuit assembly includes a first connecting pipe and a second connecting pipe fixedly installed on the outer wall of the slider seat. A first oil passage and a second oil passage are provided in the wall of the slider seat. The two ends of the first oil passage are respectively connected to the first hydraulic oil chamber and the first connecting pipe. The two ends of the second oil passage are respectively connected to the first hydraulic oil chamber and the second connecting pipe. The oil ports of the first oil passage and the second oil passage connected to the first hydraulic oil chamber are respectively located on both sides of the first piston.

[0009] Optionally, the positioning structure includes two stop blocks disposed on the side of the first piston facing the cover plate, an electromagnet is embedded on the side of the stop blocks facing the first piston, two iron plates are embedded on the side of the first piston facing the electromagnet, and a fixing component that cooperates with the stop blocks is installed on the slider seat.

[0010] Optionally, the fixing component includes mounting plates respectively disposed on both sides of the slider seat, and the ends of the two stop blocks that are far apart are respectively fixedly connected to the corresponding mounting plates. The mounting plates and the slider seat are detachably connected by a number of first bolts.

[0011] Optionally, the slider seat and the cover plate are detachably connected by a number of second bolts.

[0012] Optionally, the auxiliary hydraulic circuit assembly includes a control disc disposed on the side of the first piston away from the first piston rod. The control disc is in contact with the first piston. A plurality of third oil passages are formed in the wall of the first piston rod. The two ends of the third oil passages are respectively connected to the second hydraulic oil chamber and the external space of the first piston rod. A plurality of fourth oil passages are formed on the first piston. The rodless chamber and the second hydraulic oil chamber separated by the first piston are connected through the fourth oil passages. A plurality of through holes that cooperate with the fourth oil passages are formed on the control disc. A rotating structure that cooperates with the control disc is installed on the first piston.

[0013] Optionally, the rotating structure includes a rotating shaft fixedly installed on the side of the control panel facing the first piston. A movable chamber is formed inside the first piston. The rotating shaft and the first piston are rotatably connected. A movable frame located inside the movable chamber is sleeved on the outside of the rotating shaft. Several fixed balls are fixedly connected to the inner wall of the movable frame. Several spiral grooves that cooperate with the fixed balls are formed on the rotating shaft. The fixed balls are slidably installed in the corresponding spiral grooves. Several support rods are fixedly connected to the side of the movable frame away from the control panel. The end of the support rod away from the movable frame is located on the side of the first piston facing the first piston rod. A reset component that cooperates with the movable frame is installed in the movable chamber. A pusher for pushing the support rod to translate relative to the first piston is installed on the slider seat.

[0014] Optionally, the reset component includes several guide posts fixedly installed in the movable chamber. The guide posts pass through the movable frame. Several grooves are provided on the side of the movable frame away from the support rod. Compression springs are provided in the grooves, and the two ends of the compression springs are fixedly connected to the inner wall of the grooves and the inner wall of the movable chamber, respectively. The side of the movable frame away from the control panel is in contact with the inner wall of the movable chamber.

[0015] Optionally, the pusher includes a third piston slidably mounted in the first hydraulic oil chamber, with the first piston rod passing through the third piston. The third piston is located on the side of the stop block away from the first piston. A third connecting pipe is fixedly connected to the outer wall of the slider seat. A fifth oil passage is provided in the wall of the slider seat. The two ends of the fifth oil passage are respectively connected to the first hydraulic oil chamber and the third connecting pipe. The oil port of the fifth oil passage connected to the first hydraulic oil chamber is located on the side of the third piston away from the first piston. The oil port of the second oil passage connected to the first hydraulic oil chamber is located on the side of the third piston facing the first piston.

[0016] The beneficial effects of the present invention are as follows: by setting the coordinated action of the first piston and the second piston, the slider seat can slide relative to the first piston to generate the first stage of stroke. After the positioning structure locks the first piston, the slider seat, the first piston and the first piston rod can slide relative to the second piston rod to generate the second stage of stroke. The two-stage stroke superposition enables a larger drive stroke within a limited space, making it particularly suitable for deep-cavity molds or applications requiring a long core-pulling stroke. The first hydraulic oil chamber is directly located inside the slider seat, and the second hydraulic oil chamber is located inside the first piston rod. The cylinder structure is integrated into the slider seat and piston rod, eliminating the need for a separate cylinder body. This effectively reduces the axial and radial dimensions of the overall device and avoids the drawback of traditional external cylinders occupying mold space. The first piston is fixed in a preset position by a positioning structure, ensuring that the first piston and first piston rod remain stationary relative to the slider seat during the second-stage stroke. This ensures that the driving force of the second piston is entirely converted into the sliding of the first piston rod relative to the second piston rod, making the action sequence controllable. The main hydraulic circuit assembly and the auxiliary hydraulic circuit assembly are integrated into the slider seat, the first piston, and the first piston rod, respectively, reducing the layout of external pipelines, lowering the risk of hydraulic leakage, simplifying the assembly process, and improving production efficiency.

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0032] Example 1, by Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 The present invention includes a slider seat 1 and a cover plate 2 detachably mounted on the outer wall of the slider seat 1. A first hydraulic oil chamber 3 is provided on the side of the slider seat 1 facing the cover plate 2. A first piston 4 is slidably disposed in the first hydraulic oil chamber 3. A first piston rod 5 is fixedly connected to the side of the first piston 4 facing the cover plate 2, and the first piston rod 5 passes through the cover plate 2.

[0033] A second hydraulic oil chamber 6 is provided on the side of the first piston rod 5 facing the first piston 4. A second piston 7 is slidably provided in the second hydraulic oil chamber 6. A second piston rod 8 is fixedly connected to the side of the second piston 7 away from the first piston 4, and the end of the second piston rod 8 away from the first piston 4 passes through the first piston rod 5.

[0034] The slider seat 1 is equipped with a main hydraulic circuit assembly. The first hydraulic oil chamber 3 is divided into a rodless chamber and a rod chamber by the first piston 4. The main hydraulic circuit assembly supplies and returns oil to the rodless and rod chambers separated by the first piston 4. The first piston 4 and the first piston rod 5 are equipped with a secondary hydraulic circuit assembly, which supplies and returns oil to both sides of the second hydraulic oil chamber 6 separated by the second piston 7. The slider seat 1 is equipped with a positioning structure for fixing the first piston 4 in a preset position. The operator slides the slider seat 1 onto the mold frame. The end of the second piston rod 8 located outside the first piston rod 5 is fixedly installed on the mold frame. When it is necessary to drive the slider seat 1 to move, the external oil supply and return device adds hydraulic oil to the rodless chamber of the first hydraulic oil chamber 3 through the main hydraulic circuit assembly. Hydraulic oil is extracted from the rod chamber of the first hydraulic oil chamber 3 to allow the slider seat 1 to slide relative to the first piston 4, the first piston rod 5, and the second piston rod 8, thereby enabling the slider seat 1 to translate relative to the mold frame. When the first piston 4 is located at a preset position within the first hydraulic oil chamber 3, the position of the first piston 4 is positioned by a positioning structure to fix the first piston 4 relative to the slider seat 1. Then, the external oil supply and return equipment adds hydraulic oil to the portion of the second hydraulic oil chamber 6 that is separated from the second piston rod 8 by the second piston 7 through the auxiliary hydraulic oil circuit assembly, and extracts hydraulic oil from the portion of the second hydraulic oil chamber 6 that is separated from the second piston rod 8 by the second piston 7, so that the slider seat 1, the first piston 4, and the first piston rod 5 can slide relative to the second piston rod 8 and the mold frame.

[0035] Example 2, based on Example 1, is... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 9 and Figure 10The main hydraulic circuit assembly includes a first connecting pipe 13 and a second connecting pipe 14 fixedly installed on the outer wall of the slider seat 1. A first oil passage 9 and a second oil passage 10 are formed within the wall of the slider seat 1. The two ends of the first oil passage 9 are connected to the first hydraulic oil chamber 3 and the first connecting pipe 13, respectively. The two ends of the second oil passage 10 are connected to the first hydraulic oil chamber 3 and the second connecting pipe 14, respectively. The oil ports of the first oil passage 9 and the second oil passage 10 that connect to the first hydraulic oil chamber 3 are located on both sides of the first piston 4. The positioning structure includes a section located on the first piston 4 facing the cover plate 2. Two stop blocks 15 are provided on one side. An electromagnet 16 is embedded on the side of the stop block 15 facing the first piston 4. Two iron plates 17 are embedded on the side of the first piston 4 facing the electromagnet 16. A fixing component that cooperates with the stop block 15 is installed on the slider seat 1. The fixing component includes mounting plates 18 respectively provided on both sides of the slider seat 1. The ends of the two stop blocks 15 that are far apart are respectively fixedly connected to the corresponding mounting plates 18. The mounting plates 18 and the slider seat 1 are detachably connected by a number of first bolts 19. The slider seat 1 and the cover plate 2 are detachably connected by a number of second bolts 20.

[0036] The first connecting pipe 13 and the second connecting pipe 14 are fixedly connected to the supply and return oil pipes of the external oil supply and return equipment, respectively. The external oil supply and return equipment adds hydraulic oil to the rodless chamber of the first hydraulic oil chamber 3 through the first connecting pipe 13 and the first oil passage 9. The external oil supply and return equipment extracts hydraulic oil from the rod chamber of the first hydraulic oil chamber 3 through the second connecting pipe 14 and the second oil passage 10, which allows the slider seat 1 and the first hydraulic oil chamber 3 to slide relative to the first piston 4 and the mold frame. The slider seat 1 drives the stop block 15 to move toward the first piston 4. When the stop block 15 and the first piston 4 are in contact, the iron plate 17 and the electromagnet 16 are in contact. At this time, the electromagnet 16 is turned on, and the electromagnet 16 applies magnetic force to the iron plate 17, which allows the first piston 4 and the iron plate 17 to move relative to the electromagnet 16. When the stop block 15 and the slider seat 1 are fixed, and it is necessary to remove the first piston 4 and the first piston rod 5 from the first hydraulic oil chamber 3, the operator drives the first bolt 19 to rotate so that the first bolt 19 disengages from the slider seat 1 and the mounting plate 18, thereby releasing the fixation on the mounting plate 18. The operator then drives the mounting plate 18 and the stop block 15 to move so that the stop block 15 is pulled out of the first hydraulic oil chamber 3, preventing the stop block 15 from interfering with the first piston 4 sliding out of the first hydraulic oil chamber 3. Then, the operator drives the second bolt 20 to rotate so that the second bolt 20 disengages from the slider seat 1 and the cover plate 2, thereby releasing the fixation on the cover plate 2. The operator then drives the cover plate 2 and the first piston rod 5 to move, and the first piston rod 5 can drive the first piston 4 to be pulled out of the first hydraulic oil chamber 3.

[0037] Example 3, based on Example 2, by Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 The auxiliary hydraulic circuit assembly includes a control disc 21 located on the side of the first piston 4 away from the first piston rod 5. The control disc 21 is in contact with the first piston 4. Several third oil passages 11 are formed within the wall of the first piston rod 5. The two ends of each third oil passage 11 are connected to the second hydraulic oil chamber 6 and the external space of the first piston rod 5, respectively. Several fourth oil passages 12 are formed on the first piston 4. The rodless chamber of the first hydraulic oil chamber 3, separated by the first piston 4, and the second hydraulic oil chamber 6 are connected through the fourth oil passages 12. Several through holes 22 that mate with the fourth oil passages 12 are formed on the control disc 21. A device that mates with the control disc 21 is mounted on the first piston 4. The rotating structure includes a rotating shaft 23 fixedly mounted on the control panel 21 facing the first piston 4. A movable chamber 24 is formed inside the first piston 4. The rotating shaft 23 and the first piston 4 are rotatably connected. A movable frame 25 is sleeved on the outside of the rotating shaft 23, located within the movable chamber 24. Several fixed balls 31 are fixedly connected to the inner wall of the movable frame 25. Several spiral grooves 32 that cooperate with the fixed balls 31 are formed on the rotating shaft 23, and the fixed balls 31 are slidably installed in their corresponding spiral grooves 32. Several support rods 26 are fixedly connected to the side of the movable frame 25 away from the control panel 21, and the end of the support rod 26 away from the movable frame 25 is located at... The first piston 4 faces the first piston rod 5. A reset component that cooperates with the movable frame 25 is installed in the movable chamber 24. A pusher for pushing the support rod 26 to translate relative to the first piston 4 is installed on the slider seat 1. The reset component includes several guide posts 27 fixedly installed in the movable chamber 24. The guide posts 27 penetrate the movable frame 25. Several grooves 29 are opened on the side of the movable frame 25 away from the support rod 26. Compression springs 30 are installed in the grooves 29, and the two ends of the compression springs 30 are fixedly connected to the inner wall of the grooves 29 and the inner wall of the movable chamber 24, respectively. The side of the movable frame 25 away from the control panel 21 is in contact with the inner wall of the movable chamber 24. The pushing component includes a third piston 33 slidably installed in the first hydraulic oil chamber 3, and the first piston rod 5 passes through the third piston 33. The third piston 33 is located on the side of the stop block 15 away from the first piston 4. A third connecting pipe 28 is fixedly connected to the outer wall of the slider seat 1. A fifth oil passage 34 is opened in the wall of the slider seat 1. The two ends of the fifth oil passage 34 are respectively connected to the first hydraulic oil chamber 3 and the third connecting pipe 28. The oil port of the fifth oil passage 34 connected to the first hydraulic oil chamber 3 is located on the side of the third piston 33 away from the first piston 4. The oil port of the second oil passage 10 connected to the first hydraulic oil chamber 3 is located on the side of the third piston 33 facing the first piston 4.

[0038] The third connecting pipe 28 is fixedly connected to the supply and return oil pipes of the external oil supply and return equipment. When the first piston 4 and the iron plate 17 are fixed relative to the electromagnet 16, the stop block 15 and the slider seat 1, the external oil supply and return equipment adds hydraulic oil to the part of the first hydraulic oil chamber 3 that is separated from the first piston 4 by the third piston 33 through the third connecting pipe 28 and the fifth oil passage 34. At the same time, the external oil supply and return equipment extracts hydraulic oil from the rod chamber of the first hydraulic oil chamber 3 through the second connecting pipe 14 and the second oil passage 10, so that the third piston 33 can be made to... 3 moves toward the first piston 4, and the third piston 33 presses and pushes the support rod 26 relative to the first piston 4, shortening the length of the compression spring 30. The support rod 26 drives the movable frame 25 to slide relative to the guide column 27, and the movable frame 25 drives the fixed ball 31 to slide in the spiral groove 32. The fixed ball 31 can then drive the rotating shaft 23 and the control disk 21 to rotate. When the control disk 21 drives the through hole 22 and the corresponding fourth oil passage 12 oil port to align, the third piston 33 stops moving. At this time, the external oil supply and return equipment is connected through the first connecting pipe. Hydraulic oil is added to the rodless chamber of the first hydraulic oil chamber 3 via the first oil passage 9 and the first oil passage 13. The hydraulic oil entering the rodless chamber enters the second hydraulic oil chamber 6 through the through hole 22 and the fourth oil passage 12, where it is separated by the second piston 7 and moved away from the second piston rod 8. The external oil supply and return device extracts hydraulic oil from the rod chamber of the first hydraulic oil chamber 3 through the second connecting pipe 14 and the second oil passage 10. The hydraulic oil located in the second hydraulic oil chamber 6, separated by the second piston 7 and facing the second piston rod 8, enters through the third oil passage 11. When the first hydraulic oil chamber 3 is in the rod chamber, the slider seat 1, the first piston 4 and the first piston rod 5 can slide relative to the second piston 7 and the second piston rod 8. When the third piston 33 moves away from the first piston 4, the third piston 33 no longer presses the support rod 26. The compression spring 30 drives the movable frame 25 and the support rod 26 to move in the opposite direction to the initial position. The rotating shaft 23 and the control disk 21 rotate in the opposite direction, so that the through hole 22 on the control disk 21 is misaligned with the fourth oil passage 12, so that the fourth oil passage 12 is closed.
