Description

Technical Field

[0001] This utility model relates to the field of automatic clamping technology for die casting molds, specifically an automatic clamping device for die casting molds. Background Technology

[0002] Die casting molds play a crucial role in the casting production process. The shape and size of the die casting mold directly determine the final size and shape of the casting. During the die casting process, the die casting mold needs to clamp the unformed casting inside to ensure that the casting will not push the die casting mold out due to excessive pressure. The clamping components that fix the die casting mold can ensure the stability of the die casting process. There are various automatic clamping devices for die casting molds on the market.

[0003] However, conventional automatic clamping devices for die casting molds are not convenient for automatically clamping castings. As a result, when castings need to be manually clamped, it increases the complexity of operation and labor costs. It is also inconvenient to change the shape of the die casting mold, so when different shapes of castings need to be die-cast, other casting molds need to be used, which is not very practical. Furthermore, it is not convenient to provide support when removing the parts, which may not increase the safety of workers when removing the parts. Therefore, we propose an automatic clamping device for die casting molds to solve the problems mentioned above. Utility Model Content

Therefore, when castings need to be manually clamped, it will increase the complexity of operation and labor costs. It is also not convenient to change the shape of the die casting mold. Therefore, when castings need to be die-cast into different shapes, other casting molds need to be used, which is not very practical. Furthermore, it is not convenient to provide support when picking up the parts, which may not increase the safety of workers when picking up the parts.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic clamping device for die-casting molds, comprising:

[0006] A movable plate, wherein an upper mold is provided at the upper end of the movable plate;

[0007] Also includes:

[0008] The first pulley has a movable plate at its upper end, and the outer side of the first pulley is tightly fitted with a belt body, and a threaded rod is fixedly connected to the upper end of the first pulley.

[0009] The throttle handle has a movable plate at its lower end and a limiting structure for positioning the mold at its lower end. The limiting structure includes an upper mold, a gear, and a rack plate. The gear is fixedly connected to the lower end of the throttle handle, and the rack plate is meshed with the outer sides of both the left and right ends of the gear. The outer side of the lower end of the rack plate is slidably connected to the outer side of the upper end of the upper mold.

[0010] A support frame is provided at the lower end of the throttle.

[0011] Preferably, a motor is fixedly connected to the lower end of the first pulley, and a second pulley is tightly fitted to the outer right end of the belt body.

The inner side of the insert rods is slotted with the lower mold.

[0016] Preferably, the upper mold is tightly fitted to the outer side of the upper end of the support frame.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the automatic clamping device for die casting mold can automatically clamp the die casting mold, which is more convenient to use, does not require manual clamping, reduces manual labor, can quickly change the shape of the die casting mold, avoids different shapes required for die casting, has strong practicality, and can prevent the mold from falling during the casting process, which could lead to worker injury.

[0018] 1. It is equipped with a first pulley, a belt body and a second pulley. The rotation of the first pulley drives the belt body, which is tightly attached to the outer side of the first pulley, to rotate. This causes the second pulley, which is tightly attached to the inner side of the right end of the belt body, to rotate at the same time. It also drives the threaded rod fixedly connected to the upper end of the first pulley and the second pulley to rotate. It can use a motor to drive both sides to lift and lower at the same time, avoiding the instability of the center of gravity during the lifting and lowering process.

[0019] 2. It is equipped with a movable plate, a fixed column and an upper mold. The movable plate moves up or down, causing the fixed column fixedly connected to the upper end of the movable plate to slide up or down inside the lower mold. This causes the upper mold connected to the slot on the upper side of the fixed column to move up or down, which can automatically clamp the die-casting mold.

[0020] 3. Equipped with gears, a throttle, and a rack plate, rotating the throttle causes the gear fixedly connected to the lower end of the throttle to rotate, which in turn drives the rack plate, which is meshed with the outer side of the gear, to slide on the outer side of the upper mold. When the rack plate moves inward, it connects with the internal slots at the front and rear ends of the upper mold, enabling the die-casting mold to be installed and disassembled, facilitating the replacement of different die-casting mold shapes.

[0021] 4. It is equipped with a lower mold, an upper mold, and a support frame. By flipping it inward, the support frame is rotated and connected to the upper interior of the lower mold, making the support frame vertical and tightly fitted to the lower outer side of the upper mold. This provides additional support for the mold and prevents it from falling off when removing parts.

[0022] 5. Equipped with a support frame, insert rod, and spring, the insert rod is pulled outward, causing the spring fixedly connected to the inner side of the insert rod to be compressed and deformed. This causes the inner side of the insert rod to disengage from the slot connection between it and the support frame, and the support frame to flip outward, causing the outer upper end of the support frame to disengage from the tight fit between it and the upper mold. This allows for the quick removal of the support structure and the die casting of the part. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-5 This utility model provides a technical solution: an automatic clamping device for die casting molds includes a lower mold 1, a motor 2, a first pulley 3, a belt body 4, a second pulley 5, a threaded rod 6, a moving plate 7, a fixed column 8, an upper mold 9, a gear 10, a throttle 11, a rack plate 12, a support frame 13, an insert rod 14, and a spring 15.

[0031] Existing automatic clamping devices for die casting molds are not convenient for automatically clamping castings. As a result, when castings need to be manually clamped, it increases the complexity of operation and labor costs. It is also inconvenient to change the shape of the die casting mold. Therefore, when castings of different shapes need to be die-cast, other casting molds need to be used, which is not very practical. Furthermore, it is not convenient to provide support when removing parts, which may not increase the safety of workers when they are removing parts.

[0032] The lower mold 1 has a motor 2 fixedly connected to the lower left side, and a first pulley 3 fixedly connected to the upper end of the motor 2. The outer side of the first pulley 3 is tightly fitted with a belt body 4, and the inner side of the right end of the belt body 4 is tightly fitted with a second pulley 5. The upper ends of both the first pulley 3 and the second pulley 5 are fixedly connected with threaded rods 6, and the outer side of the threaded rod 6 is threadedly connected with a movable plate 7. The upper end of the movable plate 7 is fixedly connected with a fixed post 8, and the outer side of the upper end of the fixed post 8 is connected to an upper mold 9 through a slot. The outer side of the upper end of the threaded rod 6 is rotatably connected to the inner side of the upper end of the lower mold 1.

[0033] When automatic clamping of the die-casting mold is required, the motor 2 is started, which drives the first pulley 3 fixedly connected to the upper end of the motor 2 to rotate. The transmission between the first pulley 3 and the belt body 4 drives the second pulley 5, which is tightly attached to the inner side of the right end of the belt body 4, to rotate. The first pulley 3 and the second pulley 5 rotate simultaneously, and drive the threaded rod 6 fixedly connected to the upper end of the first pulley 3 and the second pulley 5 to rotate. After the threaded rod 6 rotates, it drives the moving plate 7, which is threadedly connected to the outer side of the threaded rod 6, to move upward. At this time, the fixed column 8 fixedly connected to the upper end of the moving plate 7 moves upward or downward inside the upper end of the lower mold 1, and drives the upper mold 9, which is connected to the slot on the outer side of the upper end of the fixed column 8, to move upward or downward. This can automatically clamp the die-casting mold, which is convenient to use and does not require manual clamping, thus reducing labor costs.

[0034] A fixed column 8 is attached to a gear 10 via a slot on its upper outer side. The upper end of the gear 10 is fixedly connected to a throttle 11. The gear 10 is meshed with a rack plate 12 on its left and right outer sides. The lower outer side of the rack plate 12 is slidably connected to the upper outer side of the upper mold 9. The rack plate 12 is also connected to the upper mold 9 via a slot on its inner side.

[0035] When it is necessary to change to a different shape of die-casting mold, rotate the handle 11, which drives the gear 10 fixedly connected to the lower end of the handle 11 to rotate simultaneously. This causes the outer sides of the gear 10 to move in opposite directions, while the outer side of the lower end of the gear 12 moves in opposite directions to the outer side of the upper mold 9. This causes the inner side of the gear 12 to disengage from the slot between it and the upper mold 9. When the outer side of the lower end of the gear 12 also disengages from the slot between it and the upper mold 9, and the handle 11 is pulled upward, the outer side of the lower end of the gear 10 fixedly connected to the lower end of the handle 11 disengages from the slot between it and the fixed post 8. This pulls the upper mold 9 upward, causing the interior of the upper mold 9 to disengage from the slot between it and the fixed post 8. This allows for the replacement of the upper mold 9 and enables quick changes to the shape of the die-casting mold, avoiding the need for different shapes of die-cast parts. This method is highly practical.

[0036] The support frame 13 has its front and rear ends rotatably connected to the front and rear ends of the lower mold 1. The support frame 13 has slots inside its front and rear ends connected to insert rods 14. The insert rods 14 have slots inside their inner sides connected to the lower mold 1. The insert rods 14 have springs 15 fixedly connected to their inner sides and slide inside the lower mold 1. The upper mold 9 is tightly fitted to the outer side of the upper end of the support frame 13.

[0037] When strong support is needed when removing the casting, the insert rod 14 is pulled outward. At this time, the spring 15 fixedly connected to the inner side of the insert rod 14 is under pressure and deforms, causing the inner side of the insert rod 14 to slide outward inside the lower mold 1 and flip the support frame 13 upward, making the support frame 13 vertical. The outer side of the upper end of the support frame 13 is tightly attached to the upper mold 9, and the insert rod 14 is released. At this time, the spring 15 fixedly connected to the inner side of the insert rod 14 loses pressure and restores its elasticity, causing the inner side of the insert rod 14 to slide inward inside the lower mold 1 and connect with the support frame 13 and the internal slot of the lower mold 1, positioning the support frame 13. This can prevent the mold from falling during the casting removal process, which could cause injury to workers.
