Abstract
Description
Technical Field
[0001] This utility model relates to a mold for processing accumulator capsules, belonging to the field of mold technology. Background Technology
[0002] Accumulator capsules are key elastic energy storage components in hydraulic systems. They are typically made of oil-resistant rubber or polyurethane materials and filled with inert gas (such as nitrogen). By compressing and releasing the gas, they store and regulate hydraulic oil pressure, effectively absorbing shocks, reducing pulsations, and compensating for leaks, thereby improving system response speed and stability. They are widely used in fields such as engineering machinery and aerospace.
[0003] In the production process, existing molds typically use a direct pouring method to pour raw materials into the mold cavity, which then cools or solidifies to form the desired product. However, this traditional molding method has certain drawbacks. The molded product tends to stick tightly to the inner wall of the mold, making the demolding process extremely difficult. Operators often need to use additional tools or apply significant external force to complete the demolding. This not only increases the labor intensity of the workers but may also cause damage to the product surface or a decrease in dimensional accuracy. This inefficient demolding method significantly extends the production cycle of a single product, resulting in a reduction in overall work efficiency.
[0004] Therefore, there is an urgent need to improve the mold used for processing accumulator capsules in order to solve the above-mentioned problems. Utility Model Content
[0005] The purpose of this invention is to provide a mold for processing accumulator capsules, which facilitates mold demolding.
[0006] To achieve the above objectives, the main technical solution adopted by this utility model includes: a mold for processing accumulator capsules, comprising a base plate, a lower mold fixedly installed on the upper end of the base plate, at least two square grooves opened on the upper end of the base plate, and a demolding device provided inside the base plate;
[0007] The demolding device includes: two fixed slide rails fixedly installed on the inner wall of the base plate, a rack slidably connected to the fixed slide rails, and a gear meshing with the rack. The gear is fixedly connected to a knob via an auxiliary rod. The knob is equipped with a button. A connecting rod is fixedly installed on the upper end of the rack. An oil pipe is threadedly connected between the two connecting rods. Several atomizing nozzles are fixedly installed on the oil pipe.
[0008] Preferably, an oil box is fixedly installed on the oil pipe via a connecting pipe, and a solenoid valve is provided on the connecting pipe. The button is used to control the opening and closing of the solenoid valve.
[0009] Preferably, the connecting rod extends to the outside of the base plate through the square groove, and the oil pipe, the atomizing nozzle, the oil box, and the solenoid valve are all located above the lower mold.
[0010] Preferably, the auxiliary rod extends to the outside of the base plate, the auxiliary rod is rotatably connected to the base plate, and the knob is located outside the base plate.
[0011] Preferably, a bracket is fixedly installed on one side of the base plate, and at least two connecting slide rails are fixedly installed on the upper end of the bracket.
[0012] Preferably, a sliding block is slidably connected between the two connecting slide rails, and an electric push rod is fixedly installed on the upper end of the sliding block.
[0013] Preferably, a connecting rod is fixedly installed at the lower end of the sliding block, and an upper mold is fixedly installed at the other end of the connecting rod, with the upper mold located above the lower mold.
[0014] Preferably, a connecting plate is fixedly installed on each of the two connecting slide rails, and a first rotating rod is rotatably connected to the connecting plate.
[0015] Preferably, two fixing plates are fixedly installed on one side of the sliding block, and a second rotating rod is rotatably connected to each of the two fixing plates.
[0016] Preferably, the second rotating rod is fixedly connected to the first rotating rod via a connecting shaft, and a protective plate is fixedly installed between the two first rotating rods.
[0017] This utility model has at least the following beneficial effects:
[0018] 1. Before pouring the material into the mold slot, the operator first turns the knob, causing the knob to drive the auxiliary rod and gear to rotate together. This causes the rack connected to the gear to slide in the fixed slide rail, and then the connecting rod and oil pipe on the rack move. When the atomizing nozzle moves to the mold slot of the lower mold, the operator presses the button to activate the solenoid valve. This allows the oil in the oil box to enter the oil pipe through the connecting pipe, and then the oil in the oil pipe is sprayed into the mold slot of the lower mold through the atomizing nozzle. After the oil mist has been sprayed, the material is poured in. At this time, the oil mist isolates the material from the mold slot, which facilitates the demolding of the mold.
[0019] 2. When the operator starts the electric push rod, it can drive the sliding block to slide vertically within the connecting slide rail, which will drive the two fixed plates fixed on its surface to move vertically, and then drive the second rotating rod, which is rotatably connected to the fixed plates, to move vertically. At the same time, one end of the second rotating rod is fixedly connected to the first rotating rod through a connecting shaft. Thus, when the first rotating rod rotates, it will drive the second rotating rod to rotate together, which in turn can drive the protective plate to rotate, thus protecting the operator during the stamping process.

[0028] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0029] Examples, such as Figures 1-6 As shown, a mold for processing an accumulator capsule includes a base plate 1, a lower mold 13 is fixedly installed on the upper end of the base plate 1, at least two square grooves 14 are opened on the upper end of the base plate 1, and a demolding device is provided inside the base plate 1.
[0030] The demolding device includes: two fixed slide rails 23 fixedly installed on the inner wall of the base plate 1, a rack 22 slidably connected to the fixed slide rails 23, and a gear 21 meshing with the rack 22. A knob 16 is fixedly connected to the gear 21 via an auxiliary rod 15. A button 17 is provided on the knob 16. A connecting rod 20 is fixedly installed on the upper end of the rack 22. An oil pipe 201 is threadedly connected between the two connecting rods 20. Several atomizing nozzles 24 are fixedly installed on the oil pipe 201. Before pouring the material into the mold cavity, the operator first rotates the knob 16. The auxiliary rod 15 and gear 21 rotate together, thereby causing the rack 22, which meshes with the gear 21, to slide in the fixed slide rail 23. This causes the connecting rod 20 and oil pipe 201 on the rack 22 to move. When the atomizing nozzle 24 moves to the mold groove of the lower mold 13, the operator presses the button 17, causing the oil in the oil pipe 201 to be sprayed into the mold groove of the lower mold 13 through the atomizing nozzle 24. After the oil mist is sprayed, the material is unloaded. At this time, the material and the mold groove are isolated by oil mist, which facilitates the demolding of the mold.
[0031] It should be noted that the connecting rod 20 is a solid rod, and the oil will only remain inside the oil pipe 201. Furthermore, the thread lengths at both ends of the oil pipe 201 are different, but the directions are the same, making it easy for workers to rotate and remove it.
[0032] like Figures 2-5As shown, furthermore, an oil box 19 is fixedly installed on the oil pipe 201 via a connecting pipe 181. A solenoid valve 18 is provided on the connecting pipe 181. A button 17 is used to control the opening and closing of the solenoid valve 18. A connecting rod 20 extends to the outside of the base plate 1 through a square groove 14. The oil pipe 201, atomizing nozzle 24, oil box 19, and solenoid valve 18 are all located above the lower mold 13. An auxiliary rod 15 extends to the outside of the base plate 1 and is rotatably connected to the base plate 1. A knob 16 is located outside the base plate 1. With an oil box 19, the operator can fill the required amount of oil into the oil box 19 in advance. When the atomizing nozzle 24 is needed to spray oil mist, the operator presses the button 17 to activate the solenoid valve 18, so that the oil in the oil box 19 can enter the oil pipe 201 through the connecting pipe 181. At the same time, the knob 16 is located outside the base plate 1, which makes it easier for the operator to operate. The surface of the fixed slide rail 23 is connected to the square groove 14, so that the connecting rod 20 can extend to the outside of the base plate 1 through the square groove 14.
[0033] It should be noted that the capacity of the oil box 19 is just enough to manufacture one batch of molds. Therefore, when the oil in the oil box 19 is used up, there will still be some oil left in the oil pipe 201. At this time, the workers can separate the oil pipe 201 from the connecting rod 20 to clean the oil remaining in the oil pipe 201.
[0034] like Figures 1-3 As shown, further, a bracket 2 is fixedly installed on one side of the base plate 1. At least two connecting slide rails 3 are fixedly installed on the upper end of the bracket 2. A sliding block 4 is slidably connected between the two connecting slide rails 3. An electric push rod 401 is fixedly installed on the upper end of the sliding block 4. A connecting rod 11 is fixedly installed on the lower end of the sliding block 4. An upper mold 12 is fixedly installed on the other end of the connecting rod 11. The upper mold 12 is located above the lower mold 13. By fixing the electric push rod 401 on the sliding block 4, when the operator starts the electric push rod 401, it can drive the sliding block 4 to slide vertically within the connecting slide rail 3. At the same time, the lower end of the sliding block 4 is fixedly connected to the upper mold 12 through the connecting rod 11. Thus, when the sliding block 4 moves vertically, it drives the upper mold 12 to move vertically as well.
[0035] like Figure 1As shown, further, connecting plates 5 are fixedly installed on both connecting slide rails 3, and first rotating rods 8 are rotatably connected to the connecting plates 5. Two fixed plates 6 are fixedly installed on one side of the sliding block 4, and second rotating rods 7 are rotatably connected to both fixed plates 6. The second rotating rods 7 are fixedly connected to the first rotating rods 8 through connecting shafts 701. A protective plate 9 is fixedly installed between the two first rotating rods 8. When the sliding block 4 moves vertically, it will drive the two fixed plates 6 fixed on its surface to move vertically, which in turn will drive the second rotating rods 7 rotatably connected to the fixed plates 6 to move vertically. At the same time, one end of the second rotating rod 7 is fixedly connected to the first rotating rod 8 through connecting shafts 701. Thus, when the first rotating rod 7 rotates, it will drive the second rotating rod 8 to rotate together, which will drive the protective plate 9 to rotate, thus protecting the workers during stamping.
[0036] It should be noted that when the sliding block 4 slides down, the protective plate 9 blocks the mold position; when the sliding block 4 moves up, the protective plate 9 rotates, and the mold position is exposed.
[0037] In this embodiment, as Figures 1-6 As shown in this embodiment, the principle of a mold for processing accumulator capsules is as follows:
[0038] Before pouring the material into the mold slot, the operator first rotates knob 16, causing knob 16 to drive auxiliary rod 15 and gear 21 to rotate together. This causes rack 22, which meshes with gear 21, to slide within fixed slide rail 23. Consequently, connecting rod 20 and oil pipe 201 on rack 22 move. When atomizing nozzle 24 moves to the mold slot of lower mold 13, the operator presses button 17, activating solenoid valve 18. This allows oil from oil box 19 to enter oil pipe 201 through connecting pipe 181, and then the oil in oil pipe 201 is sprayed through atomizing nozzle 24 into the mold slot of lower mold 13. The oil mist is then sprayed... After the spraying is completed, the material is fed in. At this time, there is oil mist between the material and the mold groove to isolate it, which facilitates the demolding of the mold. At the same time, when the operator starts the electric push rod 401, it can drive the sliding block 4 to slide vertically in the connecting slide rail 3, which will drive the two fixed plates 6 fixed on its surface to move vertically, and then drive the second rotating rod 7, which is rotatably connected to the fixed plate 6, to move vertically. Meanwhile, one end of the second rotating rod 7 is fixedly connected to the first rotating rod 8 through the connecting shaft 701. Therefore, when the first rotating rod 7 rotates, it will drive the second rotating rod 8 to rotate together, which will drive the protective plate 9 to rotate, thus protecting the operator during the stamping process.
