Description

Technical Field

[0001] This utility model relates to the technical field of rapid prototyping devices for photocuring unsaturated polyester resin, and more particularly to a rapid prototyping device for photocuring unsaturated polyester resin. Background Technology

[0002] Unsaturated polyester resins are widely used in 3D printing, model making, and composite material molding due to their fast curing speed, good molding performance, and moderate cost. Photopolymerization molding technology, as a key process that utilizes the characteristics of unsaturated polyester resins, uses light sources of specific wavelengths to cause the resin to undergo a polymerization reaction and achieve curing. Its molding accuracy and efficiency directly determine the quality of the product and the production cycle. Existing rapid prototyping devices for photocuring unsaturated polyester resins often suffer from several drawbacks. Most devices employ a single, fixed light source, requiring point-by-point scanning and curing for large or complex products. This results in long curing times, hindering mass production. Furthermore, some devices suffer from poor light source focusing, leading to significant fluctuations in spot diameter and uneven cured layer thickness. Product dimensional errors can exceed ±0.1mm, failing to meet the manufacturing requirements for high-precision parts. Therefore, solutions to these technical problems are necessary.

[0014] Example: See Figure 1-5 This utility model discloses a device for rapid photocuring of unsaturated polyester resin, comprising a device housing 1, a pallet 2 fixedly mounted on one side of the upper end of the device housing 1, a laser 12 mounted on the inner side of the upper end of the device housing 1, a reflector mounted on one side of the laser 12, and a lifting mechanism mounted on the lower end of the laser 12. A drive mechanism is mounted in the device housing 1 on one side of the lifting mechanism, and a conveying mechanism is mounted on the drive mechanism. The device housing 1 forms a basic frame, and together with the pallet 2, laser 12, reflector, lifting mechanism, drive mechanism, and conveying mechanism, it facilitates rapid photocuring of unsaturated polyester resin. The drive mechanism includes a servo motor mounted vertically upward on one side of the device housing 1. The output end of the servo motor 3 is fixedly connected to the middle of the bottom surface of the drive gear. Driven gears are meshed on both sides of the drive gear. A rotating connecting rod is vertically installed in the middle of the driven gear. The connecting rod extends vertically upward through the outer shell 1 of the device and is fixed to one side of the pulley. Through the servo motor 3, drive gear, driven gear, rotating connecting rod and pulley, it is convenient to provide power to the conveying mechanism. The upper end of the outer shell 1 opposite the pallet compartment 2 is fixed with a model support plate 10 by a snap fastener. There is a certain gap between the bottom surface of the model support plate 10 and the outer shell 1 of the device. A storage compartment 8 is installed at the lower end of the model support plate 10. Through the model support plate 10, snap fastener and storage compartment 8, it is convenient to receive the photocured model and store related items.

[0015] In this invention, four second electric telescopic rods 11 are rectangularly mounted around the lower end of the laser 12 inside the device housing 1. The telescopic ends of the second electric telescopic rods 11 are fixed to the upper periphery of the positioning plate 13, and the positioning plate 13 has a slot for insertion. The positioning adjustment of related components is facilitated by the second electric telescopic rods 11 and the positioning plate 13 inside the device housing 1. The conveying mechanism includes driven pulleys equidistantly mounted at the same position as the pulleys on the upper end of the device housing 1. The pulleys and driven pulleys are mounted opposite each other on the upper end of the device housing 1, and a conveyor belt 9 is sleeved on the pulleys and driven pulleys. Plates are fixedly connected at equal intervals to the upper end of the conveyor belt 9. 14. A transmission belt is fitted between the pulleys and driven pulleys on both sides of the conveyor belt 9. Through the pulleys, driven pulleys, conveyor belt 9, discharge plate 14 and transmission belt, the orderly conveying of materials is facilitated. The lifting mechanism includes a first electric telescopic rod 6 installed vertically inside the device housing 1. The output end of the first electric telescopic rod 6 is fixed to the bottom of the lifting chamber 7. An inlet pipe and a discharge pipe are fixedly installed on the lifting chamber 7. A solenoid valve 5 is installed on the discharge pipe, and a waste liquid tank 4 is installed below the discharge pipe. Through the first electric telescopic rod 6, lifting chamber 7, inlet pipe, discharge pipe and solenoid valve 5, the lifting and discharge control of materials is facilitated.

[0016] Working Principle: In the use of this utility model, firstly, the servo motor 3 is started, which drives the drive gear to rotate through the output end, thereby causing the driven gears on both sides to mesh and rotate synchronously. Then, the pulley is driven to rotate, which in turn causes the conveyor belt 9 to rotate. Then, the tray in the tray chamber 2 is pushed into the model support plate 10 through the platen 14, thus providing a base for resin molding. Then, the first electric telescopic rod 6 is started, which pushes the lifting chamber 7 to rise and fall through the spring telescopic end. Thus, the height of the lifting chamber 7 is precisely controlled according to the required molding layer thickness, ensuring that the resin can be evenly covered on the tray. Then, the lifting chamber 7 is replenished with resin through the inlet pipe, and the unsaturated polyester resin is evenly applied to the surface of the tray. Excess resin can be discharged into the waste liquid tank 4 through the discharge pipe (controlled by the solenoid valve 5) to avoid waste. During photocuring molding, the second... The electric telescopic rod 11 pushes the positioning plate 13 down through its telescopic end, causing the insertion slot of the positioning plate 13 to engage with the edge of the tray, firmly fixing the tray in the molding position and preventing the tray from shifting during resin application and curing. Then, the laser 12 emits a laser of a specific wavelength, which, after being reflected by a mirror, precisely irradiates the surface of the unsaturated polyester resin on the tray. The resin undergoes a photocuring reaction under laser irradiation, quickly solidifying to form a layer structure of the model. After curing, the second electric telescopic rod 11 drives the positioning plate 13 to reset. Then, through the conveyor belt 9 and the mounting plate 14, a new tray is inserted into the positioning plate 13, thereby cutting the cured model from the tray to the model support plate 10 for separation. The tray then falls into the storage compartment 8, and the model support plate 10 can be removed at the same time, thus removing the molding die.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
