Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] such as Figures 1-7As shown in the figure, a resin handicraft molding device includes a base 1, a mounting plate 15, a molding die 4, and a raw material barrel 7. Rotating shafts 2 rotatably connected to the base 1 are fixedly installed on both sides of the mounting plate 15. There are multiple molding dies 4, which are arranged side by side in two groups. The molding die 4 includes two assembled molding shells 19. A fixing seat 13 for fixedly installing the molding die 4 is provided on the mounting plate 15. The fixing seat 13 is rotatably connected to the mounting plate 15, and a gear 25 is provided at the lower end of the fixing seat 13. A sliding rod 27 is slidably arranged at the center of the mounting plate 15. The sliding rod 27 has a tooth groove meshing with the gear 25. Both ends of the sliding rod 27 are located inside the two rotating shafts 2. A hydraulic transmission system for controlling the reciprocating sliding of the sliding rod 27 is connected to the two rotating shafts 2. A first power assembly 11 for driving the rotation of the rotating shafts 2 and the mounting plate is provided on the base 1. A feeding hole 41 and a sealing plug 17 are provided at the center of the top of the molding die 4. The lower end of the sealing plug 17 cooperates with the feeding hole 41. A movable plate 29 is provided above the base 1. Multiple raw material barrels 7 are provided and installed on the movable plate 29. A feeding pipe 35 cooperating with the feeding hole 41 is provided at the lower end of the raw material barrel 7. A control valve 33 is provided on the feeding pipe 35. A second power assembly 3 for driving the horizontal movement of the movable plate 29 is provided on the base 1. A third power assembly 32 for controlling the sealing state of the sealing plug 17 and the molding die 4 is further provided on the movable plate 29. A pressing member 18 for applying pressure to the sealing plug 17 is provided on the molding die 4. A recovery tank 14 is provided on the base 1 below the mounting plate 15.

[0022] The hydraulic transmission system includes a first oil pipe 16, a second oil pipe 23, an oil pump, and an electromagnetic valve. Oil cavities 26 are provided inside the two rotating shafts 2. Pistons 28 cooperating with the oil cavities 26 are provided at both ends of the sliding rod 27. The first oil pipe 16 and the second oil pipe 23 are respectively connected to one end of the two rotating shafts 2. The electromagnetic valve is connected to the oil pump, the first oil pipe 16, and the second oil pipe 23. The oil pump transports hydraulic oil through the electromagnetic valve into the first oil pipe 16 or the second oil pipe 23. When hydraulic oil enters the first oil pipe 16, the sliding rod 27 can be pushed to slide in one direction, so as to drive all the gears 25 to start rotating, while the hydraulic oil in the second oil pipe 23 returns. When hydraulic oil enters the second oil pipe 23, the sliding rod 27 can be pushed to slide in the other direction, causing all the gears 25 to rotate in the reverse direction. By controlling the sliding distance of the sliding rod 27 and the number of teeth of the gear 25, the angle of each rotation of the gear 25 exceeds 180°, so that the resin raw material can completely cover the inner walls of the two molding shells 19. The fixing seat 13 and the gear 25 are integrally provided.

[0023] The first power assembly 11 includes a first motor 20, a first driving pulley 21, and a first belt 22. A first driven pulley 24 is provided on one of the rotating shafts 2. The first motor 20 is installed on the base 1. The first driving pulley 21 is fixed to the output shaft of the first motor 20. The first belt 22 is sleeved outside the first driving pulley 21 and the first driven pulley 24. When the first motor 20 drives the first driving pulley 21 to rotate, the rotating shaft 2 is driven to rotate by means of the first driven pulley 24 and the first belt 22, so that the mounting plate 15 drives all the forming dies 4 to rotate around the axis of the rotating shaft 2.

[0024] The second power assembly 3 includes a slide plate 9, a screw rod 8, and a second motor 12. The slide plate 9 is slidably arranged on the base 1. The two ends of the screw rod 8 are rotatably connected to the base 1. The output shaft of the second motor 12 is fixedly connected to the screw rod 8. A first air cylinder 10 for driving the movable plate 29 to lift is provided on the slide plate 9. The piston 28 of the first air cylinder 10 is fixedly connected to the movable plate 29. When the second motor 12 drives the screw rod 8 to rotate, the slide plate 9 and the movable plate 29 slide horizontally synchronously, so that the relative positions of the raw material barrel 7 and the third power assembly 32 can be changed, and thus the automatic feeding action can be realized.

[0025] The third power assembly 32 includes a third motor 31, a second driving pulley 6, a second driven pulley 5, a second belt 30, and pneumatic grippers 34. There are multiple pneumatic grippers 34 and second driven pulleys 5, and a fixed shaft is connected between the two. The fixed shaft is rotatably connected to the movable plate 29. The third motor 31 is installed on the movable plate 29. The second driving pulley 6 is fixed to the output shaft of the third motor 31. The second belt 30 is sleeved outside the second driving pulley 6 and the second driven pulley 5. When it is necessary to pull out the sealing plug 17 from the forming die 4, first move the pneumatic gripper 34 to directly above the sealing plug 17, drive the movable plate 29 to descend by the first air cylinder 10, then the pneumatic gripper 34 clamps the sealing plug 17, and then drive the second driving pulley 6 to rotate by the third motor 31, so that all the second driven pulleys 5 drive the pneumatic gripper 34 and the sealing plug 17 to rotate, and the pressing member 18 releases the pressing on the sealing plug 17. When the first air cylinder 10 drives the movable plate 29 to rise, the sealing plug 17 can be separated from the forming die 4, which can prepare for adding resin raw materials to the forming die 4. At the same time, after feeding, the sealing plug 17 can be inserted into the feeding hole 41.

[0026] The pressing member 18 includes a limiting bolt 38, a spring 40 and a pressing block 36. The pressing block 36 is an L-shaped structure. The limiting bolt 38 passes through the pressing block 36 and is fixedly connected to the forming shell 19. The spring 40 is sleeved on the outside of the limiting bolt 38 and applies a force to the pressing block 36 to resist the forming shell 19. The sealing plug 17 has a horizontally arranged latch 39, and the pressing block 36 has a guide slope 37 for the latch 39 to rotate and slide into. When the sealing plug 17 is inserted into the feeding hole 41, the third motor 31 drives the second active pulley 6 to rotate in the opposite direction, so that the pneumatic clamp 34 drives the sealing plug 17 to rotate synchronously, allowing the latch 39 to rotate. Slide between the clamping block 36 and the molding shell 19. Under the action of the spring 40, the distance between one end of the guide slope 37 and the molding shell 19 is greater than the diameter of the pin 39, while the distance between the other end and the molding shell 19 is smaller than the molding mold 4. When the pin 39 rotates and slides with the sealing plug 17 to a state of conflict with the guide slope 37, the pin 39 will generate an upward thrust on the clamping block 36 and allow the clamping block 36 to continue to compress the spring 40, and the spring 40 will produce a reactionary clamping effect on the pin 39, so that the sealing plug 17 will not fall off from the molding mold 4 during the rotation of the molding mold 4 and the mounting plate 15.

[0027] Working principle: First, multiple assembled molding dies 4 are installed on the fixed seat 13, and then the sealing plug 17 is inserted into the feeding hole 41. When the resin raw material is added to the molding die 4, the first power component 11 first drives the mounting plate 15 to maintain a horizontal state, so that the molding die 4 is set upward, and then the second power component 3 drives the movable plate 29 to slide horizontally, so that the pneumatic clamp 34 moves to the top of the sealing plug 17. Relying on the first cylinder 10, the pneumatic clamp 34 and the third motor 31, the sealing plug 17 is rotated to a certain angle first, and the state of being pressed by the clamping member 18 is released, and then it is pulled out from the molding die 4. Then the movable plate 29 continues to move horizontally, so that the raw material barrel 7 moves to the top of the feeding hole 41, and the control valve 33 controls the quantitative addition of the resin raw material. In the molding mold 4, the sealing plug 17 is then reinserted into the feeding hole 41, and then the first power component 11 and the hydraulic transmission system respectively drive the mounting plate 15 and the molding mold 4 to rotate in different directions, so that the resin raw material can be evenly attached to the inner wall of the molding shell 19, and finally the sealing plug 17 is pulled out from the molding mold 4 again, and the mounting plate 15 is rotated so that the feeding hole 41 of the molding mold 4 faces downward, so that the excess resin raw material falls into the recovery tank 14, and then it is allowed to stand for a period of time to allow the first layer of resin raw material to solidify, and the previous actions are repeated. By adding and standing multiple times, the production of resin handicrafts is completed. The use of this production method effectively reduces the labor intensity of workers, and at the same time, the production quality and efficiency can be effectively improved.
