[0027] Compared with the prior art, the present invention has the following advantages:

[0028] 1) The present invention includes a material storage device, a conveying device, a glue removal device and a demoulding and disassembling device. The material storage device is used to store printing molds with materials and molds that have been demoulded. The conveying device is used to transport the printing molds on the material storage device to the glue removal device for glue removal and then to the demoulding and disassembling device for demoulding. Finally, the demoulding printing molds are stored in the material storage device again. The glue removal device is used to perform glue removal treatment on the printing molds with materials, separate the colloids adhered to the printing molds and recycle them. The demoulding and disassembling device is used to separate the materials from the printing molds, and the printing molds can be reused. The material storage device, the glue removal device and the demoulding and disassembling device of the present invention are arranged with the conveying device as the central circumference. During demoulding, the conveying device takes the materials from the material storage device and puts them into the glue removal device for degumming. Then, the conveying device removes the degummed printing mold and puts it into the demoulding and disassembling device to separate the materials and the mold. Finally, the conveying device re-stores the degummed printing molds into the material storage device to provide a clean printing mold for the next printing. The demoulding system of the present invention has good continuity in the overall demoulding process, improves the demoulding efficiency of 3D printing molds, reduces management costs, and reduces labor costs. It has the characteristics of high degree of full automation, high demoulding efficiency, and high cost performance;

[0029] 2) The material storage device, the glue cleaning device and the demoulding and disassembling device of the present invention are arranged around the central circumference of the conveying device, which can effectively reduce the floor space of the entire equipment, reduce the cost of the equipment, and improve the efficiency of demoulding;

[0030] 3) The material storage device of the present invention is symmetrically arranged, one for storing the printing mold with materials, and the other for storing the printing mold that has been demolded. This is convenient and not easy to be confused with the handling device when taking and storing materials, thereby improving production efficiency. In addition, the material storage device of the present invention includes a positioning frame and a material storage cart. When in use, the material storage cart can be pushed into the positioning frame, and the entire pushing process is positioned twice by the guide initial positioning wheel and the limit positioning, making the whole process convenient and fast;

[0031] 4) The handling device of the present invention positions the entire handling process by setting a secondary alignment component and a first visual device, wherein the first visual device is used to prevent errors in the handling process and improve efficiency, and the secondary alignment component performs secondary positioning on the captured printing mold and then accurately places it in the glue cleaning device for centrifugal glue throwing, thereby avoiding accidents caused by the mold being thrown out due to deviation in the placement position;

[0032] 5) The cleaning chamber of the present invention places the printing jigs one by one on the cleaning rotor, starts the power source and starts to rotate, driving the cleaning rotor to rotate rapidly. The printing jigs mounted on the cleaning rotor quickly throw out the colloid attached to the printing jigs due to centrifugal action, and the colloid is collected by the outer cylinder device and then sent back to the printer for use, effectively reducing the waste of colloid. In addition, the outer cylinder adopts an inclined design at one end to effectively gather and collect by its own gravity in the first time. The outer cylinder device of the present invention can effectively realize colloid recovery;

[0033] 6) The outer cylinder device of the present invention is directly connected to the main frame by a flexible connection, which effectively cuts off the vibration generated when the cleaning device is working and increases the service life of the entire equipment;

[0034] 7) When the present invention is working, the lock is driven by the third power source to further lock the barrel cover, which effectively prevents the colloid from flying away from the barrel cover during centrifugal operation, ensuring the cleanliness of the entire working environment, and at the same time prevents the printing mold from flying out directly when it falls off, thereby improving the safety performance of use;

[0035] 8) The present invention realizes automatic separation of the material and the printing mold through the demoulding and disassembling device. Specifically: the transport device puts the printing jig into the demoulding and disassembling device, and the mold positioning component positions and fixes it. Then the cutting blade component starts to move and cut the material. The material falls down and is flipped by the flip rod and falls on the receiving and outputting component. The transport device puts the empty printing jig back into the material storage device, and the receiving and outputting component outputs the material and takes it away manually. At the same time, the cleaning blade component cleans the blade of the cutting blade component. The whole process is continuous, which effectively improves production efficiency.
