[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] An adiabatic hot runner with multiple cavities in one mold, as Figure 1 shown, includes a manifold 1. Two groups of front and rear symmetric temperature sensing wires 2 are fixedly connected to the outer wall of the manifold 1. Two groups of left and right symmetric hot nozzle bases 3 are fixedly connected to the bottom end of the manifold 1. A hot nozzle 4 is arranged inside the hot nozzle base 3. A valve needle cylinder 5 is fixedly connected to the top end of the manifold 1. The output end of the valve needle cylinder 5 is movably connected to the inside of the hot nozzle 4. A connecting mechanism 6 is fixedly connected to the outside of the valve needle cylinder 5.

[0023] During use, first, after fixing the valve needle cylinder 5 inside the mounting seat 601, the rotating wheel 602 can be rotated. When the rotating wheel 602 rotates, it will drive the screw 603 to rotate. At this time, the movable block 604 will move upward on the screw 603, and at this time, the transmission plate 605 will also move accordingly. Because one side of the transmission plate 605 and one side of the slider 607 are both set at 45°, when the transmission plate 605 moves upward, it will drive the two sliders 607 to approach each other, thereby driving the limiting plate 609 to insert into the limiting groove 7, so as to achieve the function of limiting and fixing. Driving the device through the rotating wheel 602 can make the operation of personnel more convenient and fast. At the same time, the thread on the screw 603 can make the limiting plate 609 more stable, so as to prevent loosening. At the same time, when the transmission plate 605 moves downward, the limiting plates 609 will move away from each other, making it more convenient for personnel to disassemble and assemble. At the same time, the spring 608 can improve the stability of the movement of the slider 607 and prevent deviation.

[0024] As shown in the figure, the connecting mechanism 6 includes a mounting base 601, a rotating wheel 602, a screw 603, a movable block 604 and a transmission plate 605. The rotating wheel 602 is fixedly connected to the top end of the screw 603. The movable block 604 is threadedly connected to the bottom end of the screw 603. One end of the transmission plate 605 is fixedly connected to the inside of the movable block 604. There are two symmetrically arranged transmission plates 605 on the left and right. The other end of the transmission plate 605 is set at 45°. The mounting base 601 is fixedly connected to the valve needle cylinder 5 which is fixedly connected to the inside of the mounting base 601. The rotating wheel 602 is rotatably connected to the outside of the valve needle cylinder 5. The top end of the screw 603 is rotatably connected to the top end of the mounting base 601, and the bottom end of the screw 603 extends into the inside of the mounting base 601. The movable block 604 is movably connected to the inside of the mounting base 601. The mounting base 601 is movably connected to the top end of the flow dividing plate 1. The connecting mechanism 6 further includes a connecting plate 606, a slider 607, a spring 608 and a limiting plate 609. The slider 607 is slidably connected to the inside of the connecting plate 606. One end of the spring 608 is fixedly connected to one side of the slider 607, and the other end of the spring 608 is fixedly connected to the inside of the connecting plate 606. The top end of the limiting plate 609 is fixedly connected to the bottom end of the slider 607. A chute is opened at the bottom end of the connecting plate 606, and the top end of the limiting plate 609 is slidably connected to the inside of the chute. The other side of the connecting plate 606 extends into the inside of the mounting base 601. The other side of the slider 607 is set at 45°, and the other end of the transmission plate 605 is slidably connected to the outer wall of the slider 607. A plurality of limiting grooves 7 are opened on the outer wall of the flow dividing plate 1, and the bottom end of the limiting plate 609 is adapted to the limiting grooves 7.

[0025] After fixing the valve needle cylinder 5 inside the mounting base 601, the rotating wheel 602 can be rotated. When the rotating wheel 602 rotates, it will drive the screw 603 to rotate. At this time, the movable block 604 will move upward on the screw 603. At this time, the transmission plate 605 will also move accordingly. Because one side of the transmission plate 605 and one side of the slider 607 are both set at 45°, when the transmission plate 605 moves upward, it will drive the two sliders 607 to approach each other, thereby driving the limiting plate 609 to insert into the inside of the limiting groove 7, so as to achieve the function of limiting and fixing. Driving the device by the rotating wheel 602 can make it more convenient and fast for personnel to operate. At the same time, the thread on the screw 603 can make the limiting plate 609 more stable, thereby preventing loosening. At the same time, when the transmission plate 605 moves downward, the limiting plates 609 will move away from each other, making it more convenient for personnel to disassemble and assemble. At the same time, the spring 608 can improve the stability of the slider 607 during movement and prevent deviation.

[0026] The working principle is as follows:

[0027] After fixing the valve needle cylinder 5 inside the mounting seat 601, the runner 602 can be rotated. When the runner 602 rotates, it will drive the screw 603 to rotate. At this time, the movable block 604 will move upward on the screw 603, and the transmission plate 605 will also move accordingly. Because one side of the transmission plate 605 and one side of the slider 607 are both set at 45°, when the transmission plate 605 moves upward, it will drive the two sliders 607 to approach each other, thereby driving the limiting plate 609 to insert into the inside of the limiting groove 7, so as to achieve the function of limiting and fixing. Driving the device through the runner 602 can make it more convenient and fast for personnel to operate. At the same time, the thread on the screw 603 can make the limiting plate 609 more stable, thereby preventing loosening. At the same time, when the transmission plate 605 moves downward, the limiting plates 609 will move away from each other, making it more convenient for personnel to disassemble and assemble. At the same time, the spring 608 can improve the stability of the slider 607 during movement and prevent deviation.
