[0017] The present utility model will now be further described in detail with reference to the drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.
[0018] Figure 1 is a schematic structural diagram of the present utility model; Figure 2 is a schematic structural diagram of the mold core of the present utility model.
[0019] Combined with the attached Figure 1 and the attached Figure 2 As shown, a glue-feeding balanced injection mold includes a mold base 1, a mold core 2, a vertical glue channel 3, a horizontal glue channel 4, a cooling pipe 5, and a product groove 6. The mold core 2 is fixed in the mold base 1. There are several product grooves 6 on the mold core 2, and several product grooves 6 are annularly distributed on the mold core 2. There is a vertical glue channel 3 at the center of the mold core 2, and several horizontal glue channels 4 are distributed on the mold core 2. The inlets of several horizontal glue channels 4 are all connected to the bottom outlet of the vertical glue channel 3, and the outlets of several horizontal glue channels 4 are respectively located on several product grooves 6. The cooling pipe 5 is connected to the mold core 2, and the vertical glue channel 3 and the horizontal glue channel 4 are perpendicular to each other.
[0020] One end of the cooling pipe 5 is connected to the mold core 2, and the other end of the cooling pipe 5 is located at the opening on the side of the mold base 1.
[0021] There are several mold bases 1 arrayed on the mold base 1, and the outer ends of several cooling pipes 5 are respectively located on both sides of the mold base 1.
[0022] The front end of the mold base 1 is provided with a threaded hole 7 for connecting a hanger.
[0023] A heating pipe is provided in the mold base 1.
[0024] The mold core 2 is cylindrical.
[0025] The working mode of this application is as follows: The material is injected from the top opening of a single vertical runner 3, flows down from the vertical runner 3 into several horizontal runners 4 below, and then flows from the several horizontal runners 4 simultaneously to the mold core 2 distributed in a circumferential ring around. Finally, it flows into several mold cavities on the mold core 2 almost simultaneously. In this way, the uniformity of material feeding can be maintained, and it will not be injected into the mold cavities in sequence like existing injection molds. The cooling water is directly injected into the mold core 2, which can ensure that the products in all the product mold cavities 6 on the mold core 2 can maintain a uniform cooling temperature.
