Description

Technical Field

[0001] The invention relates to the field of accumulator bladder injection, and in particular to an accumulator bladder vertical injection molding device and method. Background Art

[0002] The accumulator bladder is a product used in hydraulic accumulators. Hydraulic accumulators are high-pressure hydraulic components, mainly composed of a pressure-bearing shell, a rubber bladder and matching valves. They are widely used in the fields of automobiles, engineering machinery, shipbuilding, aerospace, etc. The bladder accumulator uses the contraction and expansion process of the bladder (the compressibility of the gas) to achieve the storage and release of energy in the hydraulic system. The fatigue life of the bladder is the core indicator that determines the quality and reliability of the hydraulic accumulator. At present, the domestic accumulator rubber bladder is a multi-stage bonding structure. This is because the domestic production process is still split-type compression molding, using a flat vulcanizer to make the rubber material separately molded in multiple molds (the upper half of the bladder, the lower half of the bladder), and then spliced ​​with glue to form the final bladder. Obviously, this kind of bonded bladder has discontinuous material areas, small deformation, insufficient bearing capacity, high bonding environment requirements and poor fatigue resistance. During use, stress concentration is easily formed at the joints, causing premature cracking and failure of the bladder. It cannot meet the needs of the accumulator to recover and store energy for a long time, absorb pressure pulsation and alleviate hydraulic shock, which seriously affects the overall quality and service life of the bladder accumulator, especially the market demand for high-end accumulators. For example, in order to improve quality and reliability, hydraulic systems in the automotive, aerospace, electronics and other fields in my country still use imported bladders and accumulators.

The machine base plate 203 is fixedly arranged on the lifting base. A support block is arranged on the machine base plate 203 and is fixed to the machine base 1. Two tracks 204 are arranged on the machine base plate 203. A top cylinder mounting plate 202 is arranged on the two tracks 204. The top cylinder device 2 is arranged on the top cylinder mounting plate 202. At the same time, a pull block is arranged on the side of the top cylinder mounting plate 202. The pull block 205 is fixedly connected to the top cylinder mounting plate 202. A telescopic motor 206 is arranged on the pull block 205. The telescopic motor 206 is arranged inside the lifting machine base. And a track 204 is arranged on the lifting base. The middle of the lifting base is open, which is convenient for the telescopic rod of the telescopic motor 206 to move. The telescopic motor 206 does not move on the lifting machine base. When the telescopic motor 206 moves and retracts, it pulls the pull block 205 to move, thereby driving the top cylinder mounting plate 202 to move on the track 204 and moving the top cylinder device 2 to the lower side of the lifted lifting plate 3.

[0037] A fixed plate 510 of the lifting device is provided with an injection structure 5. A fixed panel 507 is arranged on the injection structure 5. Support rods 505 are arranged at the four corners of the fixed panel 507. A rack is arranged on the bottom side of the support rod 505. A smooth rod 506 is arranged on the fixed plate 510. Gears are arranged on both sides of the smooth rod 506. The gears at both ends are just arranged on the support columns 505 in the same column. Since the gears are engaged with the rack, and at the same time, this smooth rod 506 is fixedly installed in the fixed plate 510. And a front and rear hydraulic system 508 is vertically and fixedly arranged on the side edges of the fixed plate 501 and the fixed panel 507. When the front and rear hydraulic system 508 contracts, it will drive the fixed panel 507 to fall. When the fixed panel 507 falls, it will move the support rod 505. When the support rod 505 moves, it will drive the gear to rotate. When the gear rotates, the smooth rod 506 rotates itself. In this way, during injection, the injection structure can be kept in close contact with the mold opening to prevent material leakage during injection. A position for an injection motor 501 is arranged in the middle of the fixed panel 507. An injection pipe 504 is arranged on the injection motor 501. Four injection hydraulic systems 502 are arranged around the injection motor 501 to control and maintain the injection pressure and stability.

During injection, the hydraulic system 502 drives the feeding screw 503 to extrude downward through the set injection pressure, and the material in the barrel is extruded into the vertical mold device through the injection port.

[0038] The vertical mold device 6 is provided with a base 601, which is fixed on the lifting plate 3. On the upper side of the base 601, there are a raised plate 602 and a guide post 603. A raised structure is provided on the raised plate 602, and the guide post 603 is vertically arranged. The vertical mold device 6 is also provided with an outer mold 611, which is arranged on the lower side of the fixed plate 510. On the outer mold 611, there is a fitting plate 604. Concave structures are provided on the side plates of the fitting plate 604, and the concave structures are mutually fitted and snapped into the raised structures on the raised plate 602. At the same time, holes are provided on the fitting plate 604, and the size of the holes is just large enough to pass through the guide post 603. A bottom template 606 is arranged on the base 601, a mold 605 is arranged on the bottom template 606, a mold block 609 is arranged inside the outer mold 611, a top template 607 is arranged on the top of the mold block 609, a filling rod 608 is arranged on the top template 607, and a filling port 610 is arranged on the filling rod 608. When the top template 607 and the bottom template 606 are closed for molding, a gap is formed between the mold 605 and the mold block 609, which is the glue injection space. The filling rod 608 is divided into a positioning filling rod and a forming filling rod. The filling ports of the positioning filling rod are arranged on both sides of the cone, and the filling port 610 is just aligned with the glue injection space. The filling port of the forming filling rod is vertically downward and is used to seal the bladder. The two glue injection rods can be replaced manually for use.

[0039] The operation steps of an accumulator bladder vertical injection molding device are as follows: S1: Start the lifting device, raise the lifting plate 3 on the lifting device. During the rising process of the lifting plate 3, the vertical mold device 6 is driven to rise and close for molding. S2: Start the top cylinder device 2, move the top cylinder device 2 to the lower side of the lifting plate 3, and the top cylinder on the top cylinder device 2 presses against the lifting plate 3. S3: Feed through the injection tube 503 on the injection structure 5. The rubber material in the barrel is first preheated to 60°C - 70°C, and then the fixed panel 507 on the injection structure 5 is locked by the front and rear hydraulic systems 508. The feeding screw 503 in the injection tube 503 pushes the material into the vertical mold device 6. S4: According to the rubber material consumption of a single group of products, and the characteristics of the rubber material flow rate at different pressures and temperatures, etc., feed the material with the positioning filling rod installed. S5: After the first feeding is completed, replace the mold positioning rod with the forming filling rod for secondary feeding. S6: According to the performance requirements of different products, conduct heat vulcanization of the rubber material at 160°C - 170°C after feeding. S7: After the product vulcanization reaches the requirements, open the mold and demold the product. According to the final requirements of the product, secondary processing processes are carried out on the product, including product trimming and secondary vulcanization.

[0040] The design of this device overcomes the disadvantages of small deformation, insufficient bearing capacity, and short fatigue life of multi-segment bonded rubber bladders, and can essentially extend the fatigue service life of the rubber bladders. The injection method of this product is vertical injection, which can reduce the force loss during the injection flow of the rubber compound and is suitable for the molding process of larger rubber bladders. During the injection process of this product, a relatively high pressure is required for the equipment, so customized equipment is used, and a clamping force of more than 500 tons is used for molding. The demolding of this product is also very simple. After the vertical mold device 6 is opened, the vulcanized rubber bladder can be directly removed from the mold 605 because the lower side of the rubber bladder is in an open state and can be removed from above. Since this rubber bladder is made of rubber and has elastic properties, it can be actually taken out. And the replacement of the molding injection rod can be done manually. This device is provided with a control box 7 to control the entire device.

[0041] Generally, the top cylinder of an injection press on the market is usually connected to the lower lifting plate (lower template) of the equipment. Due to the length requirement of the product, this equipment adopts the design of a movable top cylinder, which greatly reduces the overall height of the equipment and improves the stability and safety of the equipment.

[0042] This product makes the wall thickness of the product uniform by replacing the injection rod and using a positioning injection rod for the first injection.
