Description
A lifting device for injection molding production Technical Field
[0001] This utility model relates to the field of injection molding technology, specifically to an auxiliary lifting device for injection molding production. Background Technology
[0002] Injection molding is a manufacturing process widely used in plastic processing. It mainly involves heating plastic granules to a molten state, injecting them into a mold under high pressure, and then cooling them to form the desired plastic parts. Existing large injection molding machines require the injection molded parts to be transported at a high vertical level during use.
[0003] To achieve the above functions, a prior art Chinese patent (publication number: CN220201282U) discloses an injection molding part lifting mechanism, including a support base, a support frame fixedly installed on the upper end of the support base, fixed plates fixedly installed on both sides of the support frame, a wire feeding wheel rotatably connected between the fixed plates, a support rod fixedly installed between the two sides of the support frame, and a first limiting rod fixedly installed between the support frame and the support rod. The placement frame can slide on the surfaces of the first and second limiting rods by the cooperation of a winding wheel and the wire feeding wheel, thus supporting the product. Simultaneously, the winding wire can quickly rewind when the product falls to a low position and is picked up by staff, allowing the placement frame to return to its original position for reuse. The operation is simple and convenient, saving manpower while increasing the stability during lifting. The spacing between the sliding placement rods can be adjusted to accommodate products of different sizes.
[0004] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation: injection molded parts are generally placed on a platform for vertical transportation, and they are prone to falling during vertical movement, so they need to be secured during transportation. Summary of the Invention

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary lifting device for injection molding production, including a chassis, wherein a symmetrically distributed annular bracket is fixedly connected to the top of the chassis via a bracket, and two symmetrically distributed mounting seats are fixedly connected to the top of the chassis.
[0007] The ring bracket has a drive structure installed inside and a clamping structure for clamping the injection molded part installed on the outside of the ring bracket. The clamping structure includes a placement platform installed on the outside of the ring bracket, and two symmetrically distributed clamping blocks are installed on the top of the placement platform. An airbag is fixedly connected to the side of the two clamping blocks that are close to each other.
[0008] Preferably, an annular guide rail is fixedly connected to the outer side of the annular bracket, and the annular guide rails on the outer sides of the two annular brackets are symmetrically distributed, and the storage platform is installed between the two annular brackets.

[0024] 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.
[0025] Example 1: Please refer to Figures 1-6. This utility model provides the following technical solution: An auxiliary lifting device for injection molding production includes a chassis 1. A symmetrically distributed annular support 2 is fixedly connected to the top of the chassis 1 via a bracket, and two symmetrically distributed mounting seats 3 are fixedly connected to the top of the chassis 1. A driving structure is installed inside the annular support 2, and a clamping structure for clamping the injection molded part is installed on the outside of the annular support 2. The clamping structure includes a placement platform 6 installed on the outside of the annular support 2, and two symmetrically distributed clamping blocks 7 are installed on the top of the placement platform 6. An airbag 8 is fixedly connected to the side of the two clamping blocks 7 that are close to each other. An annular guide rail 4 is fixedly connected to the outside of the annular support 2, and the annular guide rails 4 on the outside of the two annular supports 2 are symmetrically distributed. The placement platform 6 is installed on the two annular supports. Between 2; a pair of distributed moving blocks 5 are fixedly connected to the side of the storage platform 6 near the annular support 2, and the moving blocks 5 are slidably connected between two annular guide rails 4 on the outside of the annular support 2. The storage platform 6 has a groove 9 in the middle, and a slider is fixedly connected to the bottom middle of the clamping block 7. The storage platform 6 is equidistantly distributed on the outside of the annular support 2. The slider is slidably connected to the inside of the groove 9, and a lead screw 10 is rotatably connected inside the groove 9. The lead screw 10 is threaded inside the slider, and the lead screw 10 is driven by a motor. The threads at both ends of the lead screw 10 are opposite in direction. Two symmetrically distributed first sensors 11 are installed on the top of the storage platform 6, and a control button 12 is fixedly connected to the middle of the side of the storage platform 6 away from the annular support 2. The control button 12 is connected to the motor that drives the lead screw 10 to rotate through wires.
[0026] When transporting injection molded parts, the injection molded parts are first placed on the storage platform 6. The first sensor 11 on the top of the storage platform 6 will detect the injection molded parts on the top of the storage platform 6. At this time, the first sensor 11 will control the motor that drives the lead screw 10 to rotate, so that the lead screw 10 drives the slider at the bottom of the clamping block 7 to slide inside the slide groove 9. Since the threads at both ends of the lead screw 10 are opposite, the lead screw 10 will drive the two clamping blocks 7 to move closer to each other, and then clamp and fix them by the air bladder 8 on the inner side of the two clamping blocks 7 and the two sides of the injection molded parts coming into contact with each other.
[0027] When the two airbags 8 and the injection molded part come into contact with each other, the part of the airbag 8 that is in contact with the injection molded part will deform. The deformed part of the airbag 8 will completely fit the outside of the injection molded part, thereby fixing the injection molded parts of different shapes and preventing them from falling off during transportation.
[0028] Because the airbag 8 has good elasticity, when the airbag 8 and the outside of the injection molded part come into contact with each other, the pressure exerted by the airbag 8 on the injection molded part is small. When the airbag 8 fixes the injection molded part, the pressure generated on the injection molded part can be evenly distributed on the outside of the injection molded part, thereby preventing the injection molded part from deforming due to external pressure before it has fully cooled down.
[0029] When the storage platform 6 transports the injection molded part to the designated height, the user can press the control button 12 to control the motor that drives the lead screw 10 to rotate, so that the lead screw 10 drives the two clamping blocks 7 to move away from each other, thereby causing the clamping blocks 7 to move the two airbags 8 away from the sides of the injection molded part, thus removing the injection molded part from the top of the storage platform 6 and completing the transportation of the injection molded part.
[0030] Example 2: Based on Example 1, a drive structure is also disclosed, the specific structure of which is as follows: The drive structure includes a drive shaft 13 installed inside two mounting seats 3, and a pulley is fixedly connected to one end of the drive shaft 13. Two symmetrically distributed drive wheels 14 are fixedly connected to the outside of the drive shaft 13, and each drive wheel 14 is installed on the inner side of the lower end of the annular bracket 2. A mounting frame 15 is fixedly connected to the top of the annular bracket 2, and a driven wheel 16 is rotatably connected inside the mounting frame 15. The two mounting frames 15 are connected to each other by a connecting rod. A drive belt 17 is rotatably connected to the outside of the driven wheel 16 and the outside of the drive wheel 14. The drive belt 17 is fixedly connected to the moving block 5. A second sensor 18 is fixedly connected between the two connecting rods.
[0031] During the movement of the storage platform 6, the pulley at the end of the drive shaft 13 is first driven to rotate by the motor. The pulley drives the drive shaft 13 to rotate inside the two mounting seats 3. At this time, the drive shaft 13 will drive the drive wheel 14 to rotate inside the lower end of the ring bracket 2. The drive wheel 14 drives the driven wheel 16 to rotate inside the mounting frame 15 through the drive belt 17 on its outer side. The driven wheel 16 will rotate inside the upper end of the ring bracket 2.
[0032] As the drive belt 17 rotates outside the drive wheel 14 and driven wheel 16, since the drive belt 17 and the moving block 5 are connected, the drive belt 17 will drive the moving block 5 to move inside the annular guide rail 4. In turn, the movement of the moving block 5 will drive the storage platform 6 to move outside the annular support 2. The annular support 2 is an annular structure. During the transportation of the injection molded part, the storage platform 6 will drive the injection molded part to move along the outside of the annular support 2. When the storage platform 6 moves to the top, the second sensor 18 will monitor the object on the top of the storage platform 6. When the second sensor 18 detects the storage platform... When a molded part is placed on the platform 6, the second sensor 18 will stop the motor of the cavity drive shaft 13 to prevent the molded part from rotating to the other side of the ring bracket 2 and falling. When the second sensor 18 does not detect the molded part on the top of the platform 6, the motor of the drive shaft 13 will continue to run, driving the drive wheel 14 on its outer side to rotate, so that the drive belt 17 continues to rotate outside the drive wheel 14 and the driven wheel 16, so that the drive belt 17 drives the platform 6 to move around the outer side of the ring bracket 2 through the moving block 5, thereby continuously transporting the molded part up and down.
