[0058] The specific application of this embodiment 1 is:

[0059] During the demoulding process, the entire mechanism can start the servo motor 414 to drive the threaded screw 415 fixed to the output shaft of the servo motor 414 to rotate. When the threaded screw 415 rotates, the threaded connection between the threaded screw 415 and the upper mold assembly 3, and the sliding fit of the upper mold assembly 3 on the side surfaces of the plurality of guide rods 411 can make the upper mold assembly 3 move upward on the side surfaces of the plurality of guide rods 411. When the auxiliary mold dragging operation is performed on the molded automobile door panel, the threaded screw 415 can be driven to rotate during the entire auxiliary demoulding process. The first bevel gear 416 fixed on the side surface of 415 rotates. When the first bevel gear 416 rotates, the first bevel gear 416 and the second bevel gear 417 can be meshed to drive the rotating shaft 408 to rotate inside the rotating shaft sleeve 407. As the rotating shaft 408 rotates inside the rotating shaft sleeve 407, the eccentric wheel 409 fixed at one end of the rotating shaft 408 rotates. When the eccentric wheel 409 fixed at one end of the rotating shaft 408 rotates, the reciprocating arm 508 that rotates and cooperates between the rotating pin 507 and the eccentric pin 410 will pull up or press down back and forth. , so that the cross slide rail 505 reciprocates between the sliding grooves 421 opened on the two inner walls of the U-shaped plate 420. When the cross slide rail 505 reciprocates between the sliding grooves 421 opened on the two inner walls of the U-shaped plate 420, the lifting arm 503 can be driven to perform repeated lifting or pressing operations through the hinged rotation between the first hinge seat 502 and the second hinge seat 504. When the lifting arm 503 performs repeated lifting or pressing operations, its hinged joint between the fourth hinge seat 514 and the third hinge seat 704 The articulated arm 515 will also be lifted up or pressed down repeatedly with the lifting arm 503, so that the articulated arm 515 will be lifted up or pressed down reciprocatingly, thereby finally driving the connecting horizontal plate 703 to move up and down reciprocatingly, and finally driving the two ejector posts 701 fixed on the top of the connecting horizontal plate 703 to move up and down inside the two connecting holes 605 respectively, and then the two ejector plates 702 respectively fixed on the top of the two ejector posts 701 will move up and down reciprocatingly inside the ejector groove 603, so as to eject the molded automobile door panel, which is convenient for the subsequent auxiliary demoulding operation;

[0060] During the reciprocating up and down movement of the two ejector plates 702 fixed on the tops of the two ejector columns 701 in the ejector groove 603, the lifting arm 503 can be hingedly rotated between the first hinge seat 502 and the second hinge seat 504 to drive the piston rod 501 to reciprocate up and down in the guide cylinder 405. When the piston rod 501 reciprocates up and down in the guide cylinder 405, as the piston rod 501 moves upward in the guide cylinder 405, the flow tube 405 is opened under the action of air pressure. 02, the second flap 422 hingedly matched with the outer top of the water-cooling box 401 on the inner wall thereof flips upward, the circulation tube 402 is opened, and the bottom of the first flap 513 hingedly matched with the top of the reciprocating ring 512 is tightly attached to the top of the reciprocating ring 512. At this time, under the action of air pressure, the water-cooling liquid in the water-cooling box 401 can be pumped between the first flap 513 and the second flap 422. Similarly, when the piston rod 501 moves downward inside the guide cylinder 405, under the action of air pressure, the second flap 422 flips downward, and the circulation tube 402 is opened. The opening is closed. At this time, the first flap 513 hingedly matched with the top of the reciprocating ring 512 turns upward, and the water-cooling liquid between the first flap 513 and the second flap 422 is pressed into the upper end of the first flap 513. In this way, the piston rod 501 moves up and down inside the guide cylinder 405 to repeatedly extract the water-cooling liquid in the water-cooling box 401, thereby forming a circulation process of the water-cooling liquid, and finally the molded automobile door panel is cooled. The whole process can further improve the molded automobile door panel through the principle of thermal expansion and contraction. During the cooling process, the two ejector plates 702 can be coordinated to move up and down reciprocatingly in the two ejector grooves 603 to avoid damage to the formed automobile door panel caused by hard top demoulding. In addition, during the demoulding process, the upward sliding process of the upper mold assembly 3 can be combined to complete the circulation of the water cooling liquid and the reciprocating ejection process of the ejector plate 702 at one time without any other additional operations or added power sources. The whole process is simple, convenient and easy to operate. Multiple auxiliary demoulding operations can be completed at one time, thereby increasing the demoulding efficiency of the automobile door panel.

[0063] Before the whole mechanism is used, the first sliding holes 606 formed through the top of the lower mold 601 can be slidably matched to the peripheral side surfaces of the guide rods 411, until the L-shaped plug-in plates 607 fixed to the peripheral side surfaces of the lower mold 601 are respectively plugged and matched with the plug-in grooves 424 in turn, and the second fixing holes 608 can be fixedly connected with the first fixing holes 404 by bolts, so that the lower mold 601 and the rectangular bottom plate 412 are connected and fixed to each other. After the fixing is completed, the second sliding holes 305 formed through the top of the upper mold 301 can be slidably matched to the peripheral side surfaces of the guide rods 411, and at the same time, the threaded holes 303 formed through the top of the rectangular plate 302 can be threadedly connected to the peripheral side surfaces of the threaded screw rods 415, and the lower mold 601 and the upper mold 301 can be overlapped with each other, so as to carry out the subsequent automobile door panel processing injection molding and demoulding process;

[0064] During the injection molding process of the automobile door panel, the raw material of the automobile door panel to be molded can be poured through the plurality of pouring tubes 304 connected to the outer top of the upper mold 301, so that the raw material of the automobile door panel to be molded finally enters between the overlapping lower mold 601 and the upper mold 301 through the plurality of pouring tubes 304 connected to the outer top of the upper mold 301, thereby completing the pouring molding process of the automobile door panel. After the pouring molding process is completed, the upper mold 301 can be driven to move upward together with the peripheral side surfaces of the plurality of guide rods 411 through the rotation of the threaded screw 415, so as to perform the later demoulding operation on the automobile door panel that has been poured and molded;

[0065] Before the later demoulding, the sealing cap 423 threadedly connected to one end of the water-cooling liquid feed pipe 427 can be unscrewed, and a certain amount of water-cooling liquid can be injected into the water-cooling liquid feed pipe 427 until the water-cooling box 401 is full of water-cooling liquid. Then, the injection of water-cooling liquid can be stopped, and the sealing cap 423 can be screwed into the inlet end of the water-cooling liquid feed pipe 427. In the later demoulding process, the water-cooling liquid inside the water-cooling box 401 can pass through the piston cylinder 403, the L-shaped circulation pipe 425, the L-shaped circulation pipe 609, the water-cooling circulation cavity 602, the L-shaped connecting conduit 611 and the L water inlet pipe 426 in sequence, so as to cool the automobile door panel during the demoulding process, and the lower mold 601 can be cooled by the cooling liquid at the same time, so as to further assist the demoulding of the already formed door panel under the principle of thermal expansion and contraction, effectively improve the demoulding efficiency, and avoid damage to the formed door panel during the demoulding process.
