Description

Technical Field

[0001] The utility model relates to the technical field of flywheel casting clamping tooling, in particular to a flywheel casting mold clamping tooling. Background Art

[0002] A flywheel is a rotating inertial energy storage device, also known as a flywheel energy storage device. It is characterized by no sliding contact and friction loss, high energy storage density, large specific power, fast charging and discharging speed, long service life and good stability. The flywheel energy storage system consists of a flywheel, motor / generator, bearings, vacuum chamber, energy management system and other components.

[0003] The flywheel casting mold clamping tool is a clamping device specially used for flywheel casting molds, which is designed to ensure the stability and precision of the mold during the casting process. This tooling uses a series of mechanical structures and operations to achieve firm clamping of the mold, thereby preventing the mold from moving or deforming during the casting process and ensuring the quality and precision of the casting. The main components of the flywheel casting mold clamping tooling include a clamping mechanism, a positioning device and a transmission system. The clamping mechanism generates sufficient clamping force through hydraulic or pneumatic pressure to firmly fix the mold on the tooling platform. The positioning device is used to ensure the accurate position of the mold on the tooling platform to prevent the mold from shifting during the clamping process. The transmission system is responsible for transmitting the clamping force and positioning signals to the corresponding actuator to realize the automated operation of the tooling.

[0004] When using the flywheel casting mold clamping tooling, first you need to place the mold on the tooling platform and accurately position it through the positioning device, then start the clamping mechanism to clamp the mold. During the clamping process, you need to ensure that the clamping force is evenly distributed to avoid deformation caused by excessive local force on the mold. At the same time, you also need to pay attention to check the fixation of the mold to ensure that the mold will not loosen or move during the casting process.

[0005] However, most existing clamping methods use pressing from the top of the mold. However, in the top pressing method, excessive pressure on the top can easily cause the two molds to not overlap tightly, and the mold is squeezed to one side, resulting in the cast workpiece being unable to be used for subsequent use, reducing production efficiency. Utility Model Content

[0006] Based on this, the purpose of the utility model is to provide a flywheel casting mold clamping tooling to solve the technical problem that most of the existing clamping methods adopt pressing from the top of the mold, but the top pressing method, the top is subjected to excessive pressure, which can easily lead to the two molds not being able to overlap tightly, and the mold is squeezed to one side, thereby causing the cast workpiece to be unable to be used for subsequent use, thereby reducing production efficiency.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flywheel casting mold clamping tooling comprises a workbench, first support blocks are fixedly installed on both sides of the top of the workbench, a cylinder is arranged on the top of the first support block, a movable block is fixedly connected to the output end of the cylinder, sliding rods are movably arranged on both sides of the movable block, a pressing block is rotatably connected to the outer side of the sliding rod, and a second support block is arranged on the outer side of the pressing block, first racks are fixedly installed on both sides of the bottom of the movable block in a symmetrical structure, clamping blocks are arranged on both sides of the top of the workbench in a symmetrical structure, second racks are fixedly installed on both sides of the clamping blocks in a symmetrical structure, a gear is arranged between the first rack and the second rack, a limiting structure is arranged on one side of the gear, a lower mold is arranged in the middle position of the top of the workbench, fixed frames are fixedly installed on both sides of the workbench, and an upper mold for cooperating with the lower mold is arranged below the fixed frame.

[0008] By adopting the above technical scheme, when in use, the upper mold is fitted with the lower mold, and then the movable block is driven to move backward by the cylinder. Through the cooperation between the slide bar and the pressure block, the slide bar can be driven to rotate 90° in the clockwise direction, thereby squeezing the upper part of the upper mold. When the movable block moves backward, through the meshing relationship between the first rack and the gear, the second rack can be driven to move in the opposite direction at the same time, so that the clamping block can clamp and fix the mold body on both sides, so as to facilitate the edge limitation of the mold body. With this structure, it is possible to solve the problem that most of the existing clamping methods use pressing from the top of the mold, but in the top pressing method, the top is subjected to excessive pressure, which can easily lead to the two molds not being able to overlap tightly, and the mold is squeezed to one side, thereby causing the cast workpiece to be unable to be used for subsequent use, reducing the technical problem of production efficiency, thereby improving the practicality and production efficiency of the entire flywheel casting mold clamping tooling.

[0009] The utility model is further configured that a plurality of groups of supporting legs are arranged at the bottom of the workbench, anti-skid rubber pads are arranged at the bottom of the supporting legs, and a hydraulic rod is fixedly installed between the fixed frame and the upper mold.

[0010] By adopting the above technical solution, the support legs and the anti-slip rubber pads are provided to cooperate with each other, so that the entire flywheel casting mold clamping tooling can stand stably on the ground for use, and through the hydraulic rod, the upper mold can be driven to move up and down to cooperate with the lower mold for flywheel casting.

[0011] The utility model is further configured that the inner side of the clamp block is a semi-arc structure, and a protrusion is fixedly installed on the bottom of the clamp block, and a first sliding groove used to cooperate with the protrusion is opened on the top of the workbench.

[0012] By adopting the above technical solution, when the inner side of the clamping block is set to a semi-arc structure, the clamping block can be better fitted with the mold body, thereby avoiding the problem of displacement of the upper mold and the lower mold after being squeezed. Secondly, through the first sliding groove opened on the top of the workbench, the clamping block can slide flexibly on the top of the workbench.

[0013] The utility model is further configured that rubber blocks are arranged on the inner side of the clamp block and the bottom of the pressing block, and the pressing block is an L-shaped structure.

[0014] By adopting the above technical solution, the rubber blocks arranged on the inner side of the clamp block and the bottom of the pressure block can better clamp and fix the mold body, and the characteristics of the rubber itself can increase the friction between the clamp block and the pressure block and the mold body, so as to improve the clamping tightness of the clamp block and the pressure block to the mold body. When the pressure block is in an L-shaped structure, the contact area with the top of the upper mold can be increased, thereby improving the clamping effect.

[0015] The utility model is further configured such that a rotating shaft is rotatably connected between the second support block and the pressure block, the pressure block is located between the movable block and the second support block, and second sliding grooves for cooperating with the sliding rod are provided on both sides of the movable block.

[0016] By adopting the above technical solution, the rotating shaft is set, so that the pressing block can be flexibly rotated in the second supporting block. When the pressing block is located between the movable block and the second supporting block, the pressing block can be flexibly rotated, thereby achieving the effect of squeezing and fixing the mold body. At the same time, through the sliding grooves provided on both sides of the mold body, the movable block can drive the pressing block to change its angle when moving forward and backward.

[0017] The utility model is further configured that the limiting structure includes a fixing block, and the inner side of the fixing block is rotatably connected to the gear.

[0018] By adopting the above technical solution, the fixed block can limit the position of the gear, so that the gear is always in a fixed position for rotation, thereby cooperating with the first rack and the second rack to work.

[0019] In summary, the utility model mainly has the following beneficial effects:

[0020] 1. The utility model drives the movable block to move backward through the cylinder, and through the mutual cooperation between the slide bar and the pressure block, the slide bar can be driven to rotate 90° in the clockwise direction, so as to squeeze the upper part of the upper mold. When the movable block moves backward, the meshing relationship between the first rack and the gear can drive the second rack to move in the opposite direction at the same time, so that the clamping block can clamp and fix the mold body on both sides, so as to limit the edge of the mold body. With this structure, the existing clamping method mostly adopts pressing from the top of the mold, but the top pressing method is too large, which can easily cause the two molds to not overlap tightly, and the mold is squeezed to one side, so that the cast workpiece cannot be used for subsequent use, reducing the technical problem of production efficiency, so that the practicality and production efficiency of the entire flywheel casting mold clamping tooling are improved;

[0021] 2. When the inner side of the clamping block of the utility model is a semi-arc structure, the clamping block can be better fitted with the mold body, thereby avoiding the problem of displacement of the upper mold and the lower mold after being squeezed. Secondly, a first sliding groove is provided on the top of the workbench so that the clamping block can slide flexibly on the top of the workbench. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] When in use, the upper mold 5 is fitted with the lower mold 6, and then the movable block 9 is driven to move backward by the cylinder 7. Through the cooperation between the slide rod 12 and the pressure block 10, the pressure block 10 can be driven to rotate 90° in the clockwise direction, thereby squeezing the upper part of the upper mold 5. When the movable block 9 moves backward, through the meshing relationship between the first rack 18 and the gear 8, the second rack 20 can be driven to move in the opposite direction at the same time, so that the clamping block 14 can clamp and fix the mold body on both sides, so as to facilitate the edge limitation of the mold body. With this structure, it is possible to solve the existing clamping method that mostly uses pressing from the top of the mold, but in the top pressing method, the top is subjected to excessive pressure, which can easily lead to the two molds not being able to overlap tightly, and the mold is squeezed to one side, resulting in the cast workpiece cannot be used for subsequent use, reducing the technical problem of production efficiency, thereby improving the practicality and production efficiency of the entire flywheel casting mold clamping tooling.

[0033] Furthermore, by providing mutual cooperation between the supporting legs 2 and the anti-slip rubber pads, the entire flywheel casting mold clamping tooling can stand stably on the ground for use, and through the hydraulic rod 4, the upper mold 5 can be driven to move up and down to cooperate with the lower mold 6 for flywheel casting. When the inner side of the clamping block 14 is a semi-arc structure, the clamping block 14 can be better fitted with the mold body, thereby avoiding the problem of displacement of the upper mold 5 and the lower mold 6 after being squeezed. Secondly, through the first slide groove 15 opened on the top of the workbench 1, the clamping block 14 can slide flexibly on the top of the workbench 1.

[0034] In this embodiment, the rubber blocks arranged on the inner side of the clamping block 14 and the bottom of the pressing block 10 can better clamp and fix the mold body, and the characteristics of the rubber itself can increase the friction between the clamping block 14 and the pressing block 10 and the mold body, so as to improve the clamping tightness of the clamping block 14 and the pressing block 10 on the mold body. When the pressing block 10 is in an L-shaped structure, the contact area with the top of the upper mold 5 can be increased, thereby improving the clamping effect. The rotating shaft 19 is arranged so that the pressing block 10 can be flexibly rotated in the second supporting block 13. When the pressing block 10 is located between the movable block 9 and the second supporting block 13, the pressing block 10 can be flexibly rotated, thereby squeezing and fixing the mold body. At the same time, through the second sliding grooves 16 opened on both sides of the movable block 9, the movable block 9 can drive the pressing block 10 to change its angle when moving forward and backward. Finally, the fixed block 17 is arranged to support and limit the position of the gear 8, so that the gear 8 is always in a fixed position for rotation, thereby cooperating with the first rack 18 and the second rack 20 to work.
