[0051] At the same time, a coolant circulation machine 6 is provided on one side of the injection molding device 1, and the output end of the coolant circulation machine 6 is connected to the liquid inlet of the fixed mold 5 through a delivery hose, and the suction end of the coolant circulation machine 6 is connected to the liquid discharge port of the fixed mold 5 through a delivery hose. It is worth noting that the specific structure and working principle of the coolant circulation machine 6 are both prior arts and do not belong to the main technical problems solved in the present invention. Therefore, they are not elaborated in the present invention. At the same time, coolant is injected into the fixed mold 5 through the coolant circulation machine 6, and the injection molded parts after injection molding are cooled by the coolant, which is convenient for the formation of the injection molded parts and the subsequent demolding of the injection molded parts.

[0052] In the present invention, by controlling to open the electric extension rod 7, the output end of the electric extension rod 7 moves toward the movable mold 3, and at this time, its auxiliary ejector rod group 32 drives the corresponding limit slider 72 to move in the slide groove of the movable mold 3, and until one end of the pressing protrusion is flush with the surface of the injection protrusion of the movable mold 3. At this time, its limit slider 72 is located on the side of the slide groove close to the fixed seat 4, and at the same time, one end of the limit plug 73 is flush with the surface of the injection protrusion of the movable mold 3.

[0053] Next, the movable mold 3 continues to move toward the fixed mold 5 until the movable mold 3 is fitted with the fixed mold 5, and the fixed mold 5 is fitted with the limiting fixing plate 41. At this time, the lampshade injection molding cavity is formed by the injection molding protrusion of the movable mold 3 and the injection molding cavity of the fixed mold 5, and at this time, one end of the cleaning block group is flush with the inner wall of the injection molding cavity of the fixed mold 5, and its reset slider 11 is located in its cavity, and then the injection molding material is injected into the lampshade injection molding cavity through the injection molding tube. After the injection molding is completed, the injection molded part is cooled by the coolant circulator 6.

[0054] When it is necessary to demold the injection molded part after molding and basically cooling, the electric telescopic rod 7 is controlled to be closed, and the output end of the electric telescopic rod 7 moves toward the fixed box 2, and at this time its auxiliary ejector rod group 32 drives the corresponding limit slider 72 to move in the slide groove of the movable mold 3, and when the limit slider 72 moves to the side of the slide groove close to the fixed box 2, the inner wall of the slide groove contacts the control switch, and the control switch controls the opening of the drive motor and the electric air pump 8 through electrical signals, and at this time the limit plug 73 is separated from the exhaust port.

[0055] At the same time, when the movable mold 3 gradually moves toward the fixed box body 2, its fixed mold 5 gradually moves away from the limiting fixing plate 41 under the action of the reset slider 11 and the second spring 12, and at the same time, its driving motor drives the first pulley 102 to rotate. Since the first pulley 102 and the second pulley 103 are connected by the belt body 104, the rotation of the first pulley 102 drives the second pulley 103 to rotate while driving the limiting block 105 to rotate. When the limiting block 105 rotates, the cleaning bristles 106 are used to clean the air delivery cavity to ensure the patency of the air delivery cavity, to ensure that the air can smoothly enter the card through hole 51, and flow into the injection cavity through the card through hole 51, to provide certain auxiliary demoulding for the injection molded parts, and to ensure that the injection molded parts can be demoulded smoothly.

[0056] At the same time, air is injected into the movable mold 3 and the fixed mold 5 through the electric air pump 8. When the air enters the second air inlet 52 and finally flows into the injection cavity through the card-arranged through hole 51, a certain separation is achieved between the injection-molded parts and the injection-molded cavity, thereby preventing the injection-molded parts from sticking in the injection-molded cavity, and providing certain auxiliary demoulding for the injection-molded parts, ensuring that the injection-molded parts can be demoulded smoothly.

[0057] At the same time, when the air enters the first air inlet 34 and finally flows toward the injection molding bump through the slide groove and the exhaust hole, a certain separation is achieved between the injection molding part and the injection molding bump, thereby preventing the injection molding part from sticking to the outside of the injection molding bump, and assisting the demolding of the injection molding part to ensure that the injection molding part can be demolded smoothly.

[0058] When the electric ejector rod 7 drives the movable mold 3 to fit with its fixed box body 2, the pressing protrusion of its auxiliary ejector rod group 32 moves toward one side of the fixed mold 5 under the action of the connecting rod, the limit fixing ring and the first spring, and pushes the injection-molded part to a certain extent, so that the injection-molded part is separated from the injection protrusion. Then the user can directly take the injection-molded part, which is convenient for demoulding of the injection-molded part, and the demoulding process is relatively convenient and labor-saving.

[0059] In the present invention, when it is necessary to demold the injection molded part, the movable mold 3 is driven gradually away from the fixed mold 5 by the electric ejector rod 7, wherein the limit slider 72 moves to make the side of the slide groove close to the fixed box body 2 contact with the control switch, thereby controlling the opening of the drive motor and the electric air pump 8, wherein air is injected into the movable mold 3 and the fixed mold 5 by the electric air pump 8, so that the injection molded part and the injection molding cavity are separated to a certain extent, and the injection molded part and the injection molding protrusion are separated to a certain extent, which plays a certain role in assisting the demolding of the injection molded part, ensuring that the injection molded part can be demolded smoothly, and at the same time, the injection molded part is pushed to a certain extent by the auxiliary ejector rod group 32, so that the injection molded part and the injection molding protrusion are separated, and then the user can directly take the injection molded part, which is convenient for the demolding of the injection molded part, and the demolding process is relatively convenient and labor-saving.

[0060] At the same time, during the demoulding process of the injection molded parts, the cleaning block group is driven to rotate by the driving mechanism 10, and then the air supply cavity is cleaned by its cleaning bristles 106 to ensure the patency of the air supply cavity and ensure that the air can smoothly enter and flow into the injection molding cavity, thereby assisting the demoulding of the injection molded parts to ensure that the injection molded parts can be demoulded smoothly.

[0061] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
