The two fixed blocks 881 are fixedly connected to the left and right ends of the top of the bottom block 886 respectively.The inner wall of the bottom of the slide groove 87 provided by the fixed seat 83 is provided with transversely distributed positioning grooves 89 on both the front and rear sides. The insert plate 885 passes through the bottom block 886 and is arranged in the positioning groove 89 provided by the fixed seat 83. Through this arrangement, the push plate 861 can be moved so that the push plate 861 and the side plate 853 limit the clamping plate 64 fixedly connected to the bottom of the mold body 62. At this time, the limiting plate 866 fixedly connected to the push plate 861 is inserted into the slot 67 provided by the clamping plate 64 to further limit the clamping plate 64. Then, the bolt 865 is rotated, and the bolt 865 drives the moving plate 863 to move, so that the moving plate 863 is tightly fitted with the top wall of the connecting groove 854, thereby realizing the limiting of the clamping plate 64 and the mold body 62. The first screw 65 is then removed and the push rod 884 is pushed upward, which drives the insert plate 885 to leave the positioning groove 89 provided in the fixed seat 83, and then the slide plate 851 is pushed. The slide plate 851 moves from the support seat 5 to the fixed seat 83 through the pulley 855 to realize the disassembly of the mold body 62. After the slide plate 851 moves to the appropriate position, the push rod 884 is released, and the return spring 887 pushes the insert plate 885 to be inserted into the positioning groove 89 provided in the fixed seat 83 through the push rod 884, so as to realize the positioning of the fixed block 881 and the slide plate 851, prevent the slide plate 851 from moving, and make the installation and disassembly of the mold body 62 more stable.

[0022] Workflow: When this large injection molding machine is in use, first turn on the power supply, then feed the material into the extrusion device 2 through the feed port of the extrusion device 2, start the hydraulic telescopic device 7 through the control body 4, the hydraulic telescopic device 7 pushes the left mold seat 611 and the mold body 62 to move, so that the two mold bodies 62 fit each other, and then the extrusion device 2 is extended through the control body 4, and the extrusion device 2 is extended into the mold seat 611 set on the right, and then the extrusion device 2 injects the melted material into the mold body 62, and at this time the control body 4 starts the circulation pump 612 and the electric fan 682, and the circulation pump 612 drives the coolant from the liquid storage shell 661 into the heat conduction pipe 618, and then the coolant enters the lower liquid separation box 616, and then enters the upper liquid separation box through the vertical pipe 617 615, and then enters the circulation pump 612 through the straight pipe 613, and finally the circulation pump 612 returns the coolant to the liquid storage shell 661 through the L-shaped pipe 614. At this time, the heat of the material in the mold body 62 enters the heat-conducting silicone plate 663 through the heat-conducting strip 63, and then the heat enters the heat-conducting plate 662 through the heat-conducting silicone plate 663. The heat-conducting plate 662 sends the heat to the coolant through the heat-conducting rod 664, and the coolant sends the heat to the heat-conducting pipe 618. At this time, the electric fan 682 drives the air to enter the mold seat 611 set on the left through the air inlet groove opened by the mold seat 611 set on the left, and then the air drives the heat on the heat dissipation fins 619 and the heat-conducting pipe 618 surface to flow downward, realizing rapid heat dissipation, and the mold is made of a plurality of heat-conducting strips 63. The heat in the mold body 62 is evenly introduced into the coolant in the liquid storage shell 661, so that the heat flow in the mold body 62 is more even, so that the material is evenly cooled from left to right, and then the control body 4 controls the hydraulic telescopic device 7 to contract, so that the two mold bodies 62 are separated, and then the plastic parts produced by injection molding are removed. When it is necessary to process plastic parts of different shapes, the support frame 81 is moved to a suitable position through the universal wheel 82, so that the first groove 84 opened by the fixed seat 83 corresponds to the second groove 9 opened by the support seat 5, and then the push rod 884 is pushed upward, and the push rod 884 moves upward on the outside of the vertical rod 883. At the same time, the push rod 884 drives the insert plate 885 to leave the positioning groove 89 opened by the fixed seat 83, and then the slide plate 851 is moved. The slide plate 851 The pulley 855 at the bottom moves from the first groove 84 of the fixed seat 83 to the second groove 9 of the support seat 5. After the slide plate 851 moves to the appropriate position, the bottom block 886 moves to the rear side of the slide groove 87 of the fixed seat 83, and then the push rod 884 is released. At this time, the return spring 887 pushes the plug plate 885 to be inserted into the positioning groove 89 of the fixed seat 83 through the push rod 884, so as to position the slide plate 851. Then, the push plate 861 is moved to make the push plate 861 fit with the clamping plate 64. At this time, the limit plate 866 fixedly connected to the push plate 861 is inserted into the slot 67 of the clamping plate 64, and then the bolt 865 is rotated. The bolt 865 is threadedly connected to the connecting block 864 to drive the moving plate 863 to move upward on the outside of the slide rod 862.The top of the movable plate 863 is tightly fitted with the top of the inner wall of the connecting groove 854 opened by the slide plate 851, so that the push plate 861 and the movable plate 863 are clamped on the slide plate 851 and the buffer pad 852, and the clamping plate 64 is limited by the side plate 853 and the limiting plate 866. Then, the first screw 65 is removed to separate the mold body 62 from the mold seat 611. According to the above method, the push rod 884 is pushed upward to make the plug plate 885 leave the positioning groove 89 opened by the fixed seat 83, and then the slide plate 851 is moved to the top of the fixed seat 83 until the bottom block 886 moves to The front side of the slide slot 87 provided in the fixing seat 83 is then released, and the push rod 884 is then released, and the return spring 887 pushes the push rod 884 to drive the insert plate 885 to be inserted into the positioning slot 89 provided in the fixing seat 83, so as to position the slide plate 851, and then the push plate 861 is moved in the opposite manner as described above, and then the mold body 62 and the clamping plate 64 are removed, and then the new mold body 62 and the clamping plate 64 are placed on the fixing seat 83, and the new mold body 62 and the clamping plate 64 are positioned in the above manner, and the new mold body 62 is reinstalled on the mold seat 611, so as to complete the replacement of the mold body 62, and the electric fan When maintenance is required for 682, the second screw 686 is removed, and then the fixing frame 681 is driven to move through the fixing plate 685, and the fixing frame 681 drives the plug 683 to leave the socket 684, so that the fixing frame 681 is taken out, and then the pull rod 692 is moved upward, and the pull rod 692 drives the installation frame 691 to move upward, and the installation frame 691 drives the clamping rod 694 to move through the rubber rod 693, and the clamping rod 694 is pushed to move toward the rubber rod 693 under the action of the clamping groove 689 provided in the fixing frame 681, and the rubber rod 693 is deformed under the action of the deformation groove 695 provided in itself, until The installation frame 691 is taken out from the fixed frame 681, and then the dust screen 688 can be replaced, and the electric fan 682 can be maintained. After the maintenance is completed, the installation frame 691 is installed back into the fixed frame 681, and the rubber rod 693 pushes the clamping rod 694 into the clamping slot 689 opened in the fixed frame 681 to achieve the installation and positioning of the dust screen 688. Then, the fixed frame 681 is installed back into the mold seat 611, and the plug 683 is inserted into the socket 684. Finally, the fixing plate 685 is positioned by the second screw 686 to complete the maintenance of the electric fan 682 and the replacement of the dust screen 688.
