Description

Technical Field

[0001] This utility model relates to the field of acrylic sheet casting technology, specifically to a highly automated acrylic sheet casting device. Background Technology

[0002] Acrylic sheet casting uses brand new MMA as raw material. Under the action of an initiator, it is heated and polymerized. When the conversion rate reaches 10%, it is cooled to room temperature, degassed, and poured into a mold made of inorganic glass. After being heated in a water bath and drying room, the material is shaped after polymerization is completed. The acrylic sheet is then coated and packaged as a finished product.

[0003] Currently, during acrylic sheet production, residual air in the mold prevents the poured material from flowing to every corner of the mold, resulting in incomplete filling and defects in the finished acrylic sheet. Previously, to address this issue, manual alternation of mold turning and pouring was used. However, this manual process was inefficient and increased the workload for workers. Therefore, we propose a highly automated acrylic sheet pouring device. Utility Model Content

[0023] like Figures 1-5As shown, this utility model provides a technical solution: a highly automated acrylic sheet casting device, comprising: a double-row ground rail 1; support columns 2 are slidably arranged on both sides above the ground rail 1, and support gripper assemblies 4 are arranged above the support columns 2; a rotary mechanism 3 is fixedly arranged on the outer side of one of the support columns 2, and the rotary mechanism 3 is used to drive at least one of the support gripper assemblies 4 to rotate; a back plate 5 is arranged between the two support gripper assemblies 4; a detachable mold 6 is arranged on the front of the back plate 5; a casting pipe 7 is arranged above the mold 6; and a vacuum exhaust pipe 8 is arranged on one side of the bottom of the mold 6; a clamping mechanism 9 is arranged on the back of the back plate 5; and grippers 10 extending beyond the front of the back plate 5 are arranged above and below the clamping mechanism 9; the clamping mechanism 9 is used to drive the grippers 10 to fix the mold 6 on the front of the back plate 5.

[0024] In this embodiment, the system includes: a double-row floor rail 1; support columns 2 are slidably arranged on both sides above the floor rail 1, and a sliding seat 21 is fixedly arranged at the bottom of the support column 2. The sliding seat 21 is connected to the floor rail 1, and a locking bolt 22 is provided on one side of the top of the sliding seat 21. The use of a double-row floor rail 1 ensures the stability of the connection of the sliding seat 21, thereby ensuring the stability of the support column 2. By loosening the locking bolt 22, the sliding seat 21 can slide freely on the floor rail 1, thereby adjusting the position of the support column 2. This system is suitable for the installation and use of molds 6 of different specifications.

[0025] In this embodiment, a support gripper assembly 4 is provided above the support column 2. The support gripper assembly 4 includes a sleeve 41, and a mandrel 42 is slidably inserted into one end of the sleeve 41. The mandrel 42 can slide inside the sleeve 41 to better clamp the back plate 5 using a fixed clamping plate 44 and a movable clamping plate 45. Several positioning bolts 43 are provided on the outer wall of the sleeve 41 and inserted into the sleeve 41. The positioning bolts 43 are used to lock and fix the mandrel 42 and the sleeve 41. A fixed clamping plate 44 is provided on one end of the mandrel 42, and a movable clamping plate 45 is provided on the other end of the mandrel 42. The back plate 5 is fixed in the gap between the fixed clamping plate 44 and the movable clamping plate 45. Multiple bolts are provided on the movable clamping plate 45. The bolts are used to fix the movable clamping plate 45 on the fixed clamping plate 44, thereby achieving stable clamping and fixing of the back plate 5.

[0026] In this embodiment, a rotary mechanism 3 is fixedly installed on the outer side of one of the support columns 2. The rotary mechanism 3 is used to drive at least one of the support gripper assemblies 4 to rotate. The rotary mechanism 3 includes a forward and reverse motor 31 fixed on the outer wall of one side of one of the support columns 2, and a reducer 32 is connected to the output shaft of the forward and reverse motor 31. A transmission shaft 33 inserted into the bushing at the top of the support column 2 is connected to one side of the reducer 32. The support gripper assembly 4 is installed at one end of the transmission shaft 33. When pouring raw materials into the mold 6, the operator starts the forward and reverse motor 31, which drives the reducer 32 to run. The reducer 32 drives the transmission shaft 33 to rotate, thereby driving the support gripper assembly 4 to rotate. At the same time, the back plate 5 and the mold 6 rotate synchronously, allowing the raw materials to flow better inside the mold 6 and fill the mold better. This improves the pouring quality of the acrylic sheet, increases the level of automation, and reduces the labor intensity of workers.

[0027] In this embodiment, a back plate 5 is provided between the two support gripper assemblies 4. A groove 51 is provided on the front periphery of the back plate 5. The mold 6 is snapped into the inside of the groove 51. A sealing strip is provided inside the groove 51. The edge of the mold 6 is inserted into the inside of the groove 51, thereby realizing a sealed and fixed connection between the mold 6 and the back plate 5. The specifications of the back plate 5 and the mold 6 are compatible. There are several back plates 5 and molds 6, which are used to process acrylic sheets of different specifications.

[0028] In this embodiment, a detachable mold 6 is provided on the front of the back plate 5. A casting pipe 7 is provided on the top of the mold 6, and a vacuum exhaust pipe 8 is provided on one side of the bottom of the mold 6. The top of the casting pipe 7 is connected to the raw material conveying pipe, and the pre-treated raw material is conveyed into the casting pipe 7 and enters the interior of the mold 6. The casting pipe 7 and the conveying pipe are sealed together, and an exhaust pipe with a one-way valve is provided on one side of the casting pipe 7. When the raw material is poured, there is a small amount of air inside the mold 6, which can be squeezed out from the exhaust pipe of the casting pipe 7, ensuring the vacuum degree inside the mold 6. The vacuum exhaust pipe 8 is connected to an external vacuum pump. By starting the vacuum pump, the interior of the mold 6 can be evacuated to a vacuum state, thereby better realizing the casting and processing of acrylic sheets.

[0029] In this embodiment, a clamping mechanism 9 is provided on the back side of the back plate 5, and clamping claws 10 extending beyond the front side of the back plate 5 are provided above and below the clamping mechanism 9. The overall structure of the clamping claws 10 is C-shaped, and the end of the clamping claws 10 that contacts the mold 6 can be set as a bevel structure. Thus, when the clamping mechanism 9 drives the clamping claws 10 to contact the mold 6, the bevel structure can be used to better fix the mold 6 with the clamping claws 10. The clamping mechanism 9 is at least used to drive the clamping claws 10 to fix and install the mold 6 on the front side of the back plate 5. The clamping mechanism 9 includes several bearing seats 91 disposed on the back of the back plate 5. A lead screw 92 is disposed between the two bearing seats 91 located in the middle, and guide rods 93 are disposed on the bearing seats 91 located on both sides. Lead screw nuts 94 are threaded onto the external of the lead screw 92. The lead screw nuts 94 are symmetrically distributed on both sides of the lead screw 92. As the lead screw 92 rotates, it can drive the two lead screw nuts 94 to move towards or away from each other, realizing the separation or approach of the gripper 10 and the mold 6 in the vertical direction. A forward and reverse motor 95 is disposed at the bottom of the lead screw 92. Connecting arms 96 are fixedly disposed on the outer walls of both sides of the lead screw nuts 94, and guide seats 97 are fixedly connected to the ends of the connecting arms 96 and sleeved on the outside of the guide rods 93. Synchronizing rods 98 are fixedly connected to the outside of the guide seats 97. One end of the gripper 10 is fixed to the synchronizing rod 98. After the module 6 is installed on the back plate 5, the operator starts the forward and reverse motor 95, which drives the lead screw 92 to rotate. The lead screw 92 can drive the lead screw nut 94 to slide linearly on the back of the back plate 5. The lead screw nut 94 drives the connecting arm 96 and the guide seat 97 to slide synchronously. The guide seat 97 slides on the guide rod 93, which plays a good guiding role. The sliding of the guide seat 97 drives the synchronizing rod 98 to move. The synchronizing rod 98 drives several grippers 10 to move synchronously. The grippers 10 are used to clamp the surface of the mold 6, thereby realizing the fixed installation of the mold 6 on the back plate 5. When removing the finished acrylic sheet after disassembling the mold 6, the mold 6 can be removed from the back plate 5 by reversing the above operation.
