DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] A hot runner flow regulating mechanism, such as Figures 1 to 4As shown, it includes a diverter plate 1, on which a liquid inlet 2 is provided, and on which two diverter channels 3 are also provided, both of which are connected to the liquid inlet 2, and flow regulating components 4 are arranged at the ends of the two diverter channels 3 away from the liquid inlet 2, and a nozzle 5 is arranged at the discharge of the flow regulating component 4, and the regulating component includes six baffles 6 which are isosceles triangles when viewed from above, and the isosceles sides of adjacent baffles 6 are slidably connected, and the baffles 6 are horizontally slidably arranged along the surface where the bottom edges thereof are located, and the central portions of the six baffles 6 are hexagonal holes.

[0019] In the above embodiment, the opening and closing of the connection between the branch channel 3 and the nozzle 5 is adjusted by adjusting the six baffles 6 on the assembly. Since the baffles 6 are isosceles triangles when viewed from above, and the isosceles sides of adjacent baffles 6 are slidably connected, when one baffle 6 is slid, the remaining baffles 6 also slide along the surface where the bottom edge is located, so that the size of the hexagonal holes in the middle of the six baffles 6 in the annular array can be adjusted, thereby achieving the effect of adjusting the flow rate of the nozzle 5.

[0020] refer to Figure 3 and Figure 4 As shown: the adjustment component also includes a mounting plate 7, one side of the mounting plate 7 is integrally formed with a connecting plate 8 fixedly connected to the branch channel 3, the side of the mounting plate 7 away from the connecting plate 8 is provided with a hexagonal sliding groove 9, the baffle 6 is integrally formed with a sliding block 10 corresponding to the sliding groove 9, the mounting plate 7 is rotatably matched with an adjustment disk 11, the adjustment disk 11 has six slots 12 in a ring array, the six baffles 6 are integrally formed with limiting columns 13, and the six limiting columns 13 are respectively slidably connected to the six slots 12.

[0021] In the above embodiment, by rotating the connecting disk 8, the slot hole 12 on the connecting disk 8 drives the baffle 6 to move through the limiting column 13. Since the slider provided on the baffle 6 corresponds to the sliding slot 9, the baffle 6 slides along the sliding slot 9, thereby achieving the purpose of adjusting the size of the hexagonal hole.

[0022] refer to Figure 3 and Figure 4 As shown: a fixed plate 14 is fixedly installed on one side of the mounting plate 7, the adjusting plate 11 and a plurality of baffles 6 are set between the mounting plate 7 and the fixed plate 14, a push rod 15 is integrally formed on one side of the adjusting plate 11, and three limit rods 16 are arranged in a circular array on the side wall of the fixed plate 14, an insertion rod 17 corresponding to the limit rod 16 is slidably installed on the push rod 15, and a slot 18 corresponding to the insertion rod 17 is opened on the limit rod 16.

[0023] In the above embodiment, three limit rods 16 are arranged in a circular array on the fixed disk 14. When the push rod 15 corresponds to the three limit rods 16 respectively, the size of the hexagonal hole is changed to be different accordingly, so that the insertion rod 17 is pulled open, the push rod 15 is pushed to correspond to the limit rod 16, and the insertion rod 17 is inserted into the slot 18, thereby achieving the effect of adjusting the size of the hexagonal hole.

[0024] Working principle:
