[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1:

[0023] See also Figure 1-3 In this embodiment, a multi-cavity injection mold capable of controlling the on-off of a diverter channel includes a frame 1, in which an auxiliary mechanism is arranged. The auxiliary mechanism includes a cylinder 2 fixedly mounted on the inner wall of the frame 1, a diverter box 3 fixedly mounted on the output end of the cylinder 2, an adjusting mechanism 4 arranged in the frame 1, a lower mold 5 fixedly mounted in the frame 1, an upper mold 6 fixedly mounted on the lower surface of the diverter box 3, and a limiting mechanism 7 arranged in the frame 1.

[0024] The regulating mechanism 4 includes a mounting block 41 fixedly mounted in the diversion box 3, a heating wire 42 fixedly mounted in the mounting block 41, a cooling fan 43 fixedly mounted in the frame 1, a water tank 44 fixedly mounted on the upper surface of the frame 1, a water pipe 45 fixedly mounted on the lower surface of the water tank 44, a water pump 46 fixedly mounted on the outer peripheral wall of the water pipe 45, and cooling fins 47 fixedly mounted on the left and right ends of the water tank 44.

[0025] In this embodiment, the limiting mechanism 7 includes a cavity 71 opened in the lower mold 5 and the upper mold 6, a diversion pipe 72 inserted into the cavity 71, an electromagnetic valve 73 fixedly installed on the outer peripheral wall of the diversion pipe 72, and a limit plate 74 fixedly installed in the diversion box 3.

[0026] In this embodiment, the diversion pipe 72 is connected to the limit plate 74. In order to allow the material in the diversion box 3 to enter the cavity 71 through the diversion pipe 72, a feed pipe is fixedly connected to the rear surface of the diversion box 3.

[0027] In this embodiment, the cooling fan 43 is located on the left side of the diversion box 3 , and the water pipe 45 is located between the cooling fan 43 and the diversion box 3 , in order to increase the cooling effect of the cooling fan 43 through the water pipe 45 .

[0028] In this embodiment, a condenser is fixedly connected to the water tank 45 , and the upper mold 5 and the lower mold 6 are adapted to each other.

[0029] Example 2:

[0030] See also Figure 1-3 A temperature sensor 8 is fixedly connected to the outer wall of the diverter box 3, and a controller is fixedly connected to the upper surface of the frame 1. The controller is electrically connected to the water pump 46, the temperature sensor 8 and the solenoid valve 73. By setting the temperature sensor 8, the temperature measured by the temperature sensor 8 can be used to facilitate the user to determine whether to heat or cool the diverter box 3.

[0031] The working principle of the above embodiment is:

[0032] When the user observes the number of the temperature sensor 8, the user starts the heating wire 42 for heating when heating is required, and starts the cooling fan 43 and the water pump 46 when cooling is required. The water pump 46 drives the liquid in the water tank 44 into the water pipe 45. The wind blown by the cooling fan 43 cools the diversion box 3 after cooling through the water pipe 45. Then the user starts the solenoid valve 73, and the material in the diversion box 3 enters the cavity 71 through the diversion pipe 72, thereby completing the entire operation process.

[0033] The above beneficial effects are:

[0034] By starting the water pump, the liquid is allowed to enter the water pipe. The air blown by the cooling fan is cooled by blowing through the liquid and thus comes into contact with the diversion box. The condenser and the heat dissipation fins can adjust the temperature of the liquid in the water tank. By starting the heating wire, the diversion box can be heated. By adjusting the temperature in the diversion box, the diversion rate can be increased, thereby solving the problem that if the material has poor fluidity, the speed of entering the cavity will be slowed down, affecting the production rate. By starting the solenoid valve, the material in the diversion box enters the cavity through the diversion pipe.

[0035] The electrical components mentioned in this article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device that controls a computer, etc., and the existing public power connection technology is not described in detail in this article.
