Description

Technical Field

[0001] This utility model relates to the field of PU synchronous belt barrel production technology, and in particular to a special mold for the production of PU synchronous belt barrels. Background Technology

[0002] Synchronous belts are a type of meshing transmission belt. Their inner surface has equally spaced teeth (such as trapezoidal teeth, circular arc teeth, HTD teeth, AT teeth, etc.). These teeth mesh with the corresponding tooth grooves on the synchronous belt pulley to achieve synchronous transmission between the driving pulley and the driven pulley without slippage. It combines the advantages of belt drive, chain drive and gear drive.

[0003] When producing synchronous belt drums, the casting mold method is usually used. However, the finished product is difficult to separate from the mold after production, requiring complex operations by the staff, which affects the next round of production, slows down production efficiency, and fails to meet the needs of the staff. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a special mold for the production of PU synchronous belt barrels.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A special mold for producing PU synchronous belt drums includes a support frame, on which a hydraulic cylinder is fixedly mounted. An upper mold is fixedly mounted on the output shaft of the hydraulic cylinder, and a lower mold is fixedly mounted on the support frame. The lower mold has an opening, and a top block is slidably connected within the opening. A connecting block is fixedly connected to the lower end of the top block. The connecting block is C-shaped and one end is fixedly mounted on the upper mold. Two mutually symmetrical vibration components are mounted on the support frame.

[0007] Preferably, the vibration assembly includes a rotating shaft rotatably mounted on a support frame, a plurality of turntables fixedly mounted on the rotating shaft, a slot on the turntable, a plurality of rotating cylinders rotatably connected in the slot, a torsion spring fixedly mounted on the rotating cylinder and the slot, a vibration block fixedly mounted on the rotating cylinder, and a control mechanism for controlling the rotation of the rotating shaft rotatably mounted on the lower mold.

[0008] Preferably, the control mechanism includes a second rotating shaft rotatably connected to the lower mold, a spur gear fixedly mounted on the second rotating shaft, a rack fixedly mounted on the connecting block, the spur gear meshing with the rack, and the first rotating shaft and the second rotating shaft connected by a belt drive assembly.

[0009] Preferably, a stabilizing block is fixedly installed on the lower mold, a supporting block is fixedly installed on the stabilizing block, and multiple air vents are opened on the supporting block, with a fan rotatably installed inside each air vent.

[0010] Preferably, two mutually symmetrical limiting blocks are fixedly installed on the connecting block, and both limiting blocks are slidably connected to the support frame.

[0011] Preferably, the lower end of the support frame is provided with anti-slip texture, which is installed in a strip shape.

[0012] 1. Compared with the prior art, the beneficial effects of this utility model are: by combining the upper mold and the lower mold with the hydraulic cylinder and completing the pouring, when the upper mold rises, the connecting block on it drives the top block to rise and pushes the finished product in the lower mold upward, so that the finished product can be quickly separated from the mold and demolded, reducing the labor of workers and preparing for the next round of production, thus improving production efficiency.

[0013] 2. When the upper mold rises, the rack and pinion, in conjunction with the spur gear, drive the second rotating shaft to rotate, which in turn drives the belt drive assembly and the first rotating shaft to rotate, causing the turntable to rotate. This causes the vibrating block to continuously vibrate the outer wall of the lower mold. The vibration can accelerate the separation between the finished product and the mold, further improving the demolding efficiency. Attached Figure Description

Detailed Implementation

[0019] Reference Figures 1-4A special mold for producing PU synchronous belt drum includes a support frame 1, on which a hydraulic cylinder 2 is fixedly installed. The hydraulic cylinder 2 is existing technology. The hydraulic cylinder 2 drives the internal piston to move by the pressure of hydraulic oil, thereby driving the object connected to the piston rod to move in a straight line. The output shaft of the hydraulic cylinder 2 is fixedly installed with an upper mold 3. A lower mold 4 is fixedly installed on the support frame 1. The lower mold 4 has an opening, and a top block 5 is slidably connected in the opening. A connecting block 6 is fixedly connected to the lower end of the top block 5. The connecting block 6 is C-shaped and one end of the connecting block 6 is fixedly installed on the upper mold 3. Two mutually symmetrical vibration components are installed on the support frame 1.

[0020] By activating the hydraulic cylinder 2, the upper mold 3 is raised or lowered. When the upper mold 3 is lowered, it is sealed with the lower mold 4. Raw materials can be injected through the feed port on the upper mold 3 to carry out production. When the upper mold 3 is raised, production is completed. When the upper mold 3 is raised, the connecting block 6 on it is raised, which in turn raises the fixedly connected top block 5, so that the top block 5 pushes the finished product out of the lower mold 4. When the upper mold 3 is lowered, the connecting block 6 is lowered and the top block 5 is reset, thus forming a sealed mold assembly.

[0021] The vibration assembly includes a rotating shaft 7 rotatably mounted on a support frame 1, multiple turntables 8 fixedly mounted on the rotating shaft 7, slots on the turntables 8, multiple rotating cylinders 9 rotatably connected in the slots, torsion springs 10 fixedly mounted together with the rotating cylinders 9 and the slots, and vibration blocks 19 fixedly mounted on the rotating cylinders 9. A control mechanism for controlling the rotation of the rotating shaft 7 is mounted on the lower mold 4.

[0022] During demolding, the rotation of the rotating shaft 7 drives the turntable 8 on the rotating shaft 7 to rotate, which in turn drives the turntable 8 and multiple rotating cylinders 9 in the slot to rotate, thereby driving the vibrating block 19 to rotate and continuously vibrate the outer wall of the lower mold 4. During the vibration process, since the rotating cylinder 9 is connected to the slot, after the vibrating block 19 hits the lower mold 4, it is squeezed by the lower mold 4. At this time, the rotating cylinder 9 drives the vibrating block 19 to rotate and adjust its position until the vibrating block 19 rotates away from the lower mold 4. The rotating cylinder 9 returns to its original position under the rebound of the torsion spring 10, thus causing the vibrating block 19 to also return to its original position.

[0023] The control mechanism includes a second rotating shaft 11 rotatably connected to the lower mold 4, a spur gear 12 fixedly mounted on the second rotating shaft 11, a rack 13 fixedly mounted on the connecting block 6, the spur gear 12 meshing with the rack 13, and a first rotating shaft 7 connected to the second rotating shaft 11 via a belt drive assembly 14. The belt drive assembly 14 consists of two pulleys and a belt body, used to transmit the rotation of the second rotating shaft 11 and drive the first rotating shaft 7 to rotate.

[0024] When the upper mold 3 rises, the connecting block 6 and its rack 13 rise synchronously, thereby driving the meshing spur gear 12 to rotate through the rack 13. The rotation of the spur gear 12 drives the rotating shaft 11 to rotate, and with the cooperation of the belt drive assembly 14, it drives the rotating shaft 7 to rotate. Therefore, when the upper mold 3 rises and drives the connecting block 6 and the top block 5 to demold, the vibrating block 19 vibrates continuously and further accelerates the demolding rate.

[0025] A stabilizing block is fixedly installed on the lower mold 4, and a support block 15 is fixedly installed on the stabilizing block. Multiple air vents 16 are opened on the support block 15, and a fan 17 is rotatably installed inside the air vents 16. The fan 17 is existing technology, which drives the rotating rod connected to its output shaft to rotate through a drive motor, and causes multiple fan blades on the rotating rod to rotate, generating wind power and performing air cooling.

[0026] During demolding, the finished product still has heat because it has just undergone casting production. At this time, it is necessary to turn on the fan 17 to generate airflow and further cool the finished product. This can help to set the shape of the demolded product and prevent the high-temperature strip from deforming.

[0027] Two symmetrical limiting blocks 18 are fixedly installed on the connecting block 6. Both limiting blocks 18 are slidably connected to the support frame 1. The limiting blocks 18 serve a stabilizing function, making the rising and falling of the connecting block 6 more stable and preventing wobbling. The lower end of the support frame 1 is equipped with anti-slip textures. The anti-slip textures are installed in a strip shape. Through the anti-slip textures, the staff can stably place the device in the designated position.

[0028] In this invention, the working principle is as follows: The hydraulic cylinder 2 is activated, causing the upper mold 3 to rise or fall. When the upper mold 3 falls, it seals with the lower mold 4, allowing raw materials to be injected through the feed inlet for production. When the upper mold 3 rises, production is complete. During this rise, the connecting block 6 rises, which in turn raises the fixedly connected top block 5, causing it to eject the finished product from the lower mold 4. When the upper mold 3 falls, the connecting block 6 falls and resets the top block 5, forming a sealed mold assembly. During the rise of the upper mold 3, the connecting block 6 and its rack 13 rise synchronously, causing the rack 13 to drive the meshing spur gear 12 to rotate. The rotation of the spur gear 12 drives the rotating shaft 11 to rotate, which, in conjunction with the belt drive assembly 14, drives the rotating shaft 11 to rotate. The shaft 7 rotates, which in turn drives the turntable 8 on the shaft 7 to rotate. This, in turn, drives the turntable 8 and multiple rotating cylinders 9 in the slot to rotate, thereby causing the vibrating block 19 to rotate and continuously vibrate the outer wall of the lower mold 4. During the vibration process, because the rotating cylinder 9 is connected to the slot, after the vibrating block 19 strikes the lower mold 4, it is squeezed by the lower mold 4. At this time, the rotating cylinder 9 drives the vibrating block 19 to rotate and adjust its position until the vibrating block 19 rotates away from the lower mold 4. The rotating cylinder 9 returns to its original position under the rebound of the torsion spring 10, thus causing the vibrating block 19 to also return to its original position. When demolding, since the finished product has just undergone casting production, it still has heat. At this time, it is necessary to turn on the fan 17 to generate airflow and further cool the finished product. This can help to shape the demolded product and prevent deformation of the high-temperature material.
