[0023] In this embodiment, an upper mold cavity 4 is opened on one side of the upper mold 1, and a lower mold cavity 5 is opened on one side of the lower mold 2. The upper mold cavity 4 and the lower mold cavity 5 are arranged opposite to each other, and the injection port 3 is connected to the lower mold cavity 5. After the upper mold 1 and the lower mold 2 are closed, injection molding can be performed through the injection port 3. This is the existing technology for injection molding of the instrument panel frame assembly and will not be repeated here.

[0024] In the present embodiment, a plurality of ejector pins 10 and ejector pins 11 are all arranged through the lower mold cavity 5, and a plurality of cylinders 12 are fixedly connected to the back side of the lower mold 2. The output ends of the plurality of cylinders 12 are all arranged through the lower mold 2 and are respectively fixedly connected to the rear end surfaces of the pressing plate 1 7 and the pressing plate 2 8. The cylinders 12 can drive the pressing plate to move, thereby driving the ejector pins to extend out of the lower mold cavity 5 to eject the cooled plastic parts, thereby assisting in the discharge of the materials.

[0025] In this embodiment, one end of the cooling pipe 9 is fixedly connected to the water outlet pipe 16, and the other end of the cooling pipe 9 is connected to the cooling groove 17. The multiple top rods 10 and the top rods 11 are made of hollow structures, and the multiple top rods 10 and the top rods 11 are connected to the cooling pipe 9, so that the coolant can enter the top rods 10 and the top rods 11, thereby accelerating heat transfer and improving the cooling effect.

[0026] In this embodiment, filter plates 14 are fixedly sleeved on the inner walls of the air inlet and outlet of the air supply fan 13. The air supply fan 13 is arranged between the multiple cylinders 12. The air supply fan 13 is mainly used to accelerate the heat dissipation efficiency.

[0027] In this embodiment, a water inlet pipe 18 is fixedly sleeved on one side of the lower mold 2, and the cooling groove 17 is connected to the water inlet pipe 18. Condensed water enters from the water inlet pipe 18, then flows into the cooling groove 17 to cool the injection port 3 and then enters the cooling pipe 9.

[0028] In this embodiment, a plurality of positioning blocks are fixedly connected to one side of the upper mold 1, and a plurality of positioning grooves are opened on one side of the lower mold 2. The plurality of positioning blocks are slidably sleeved in the plurality of positioning grooves respectively to facilitate mold closing.

[0029] It should be noted that the utility model is an injection molding mold for an instrument panel skeleton assembly with a gate cooling mechanism. When in use, the water outlet pipe 16 and the water inlet pipe 18 are respectively connected to the water inlet and outlet of the cooling water circulation supply device. When cooling after injection molding, the coolant flows from the cooling tank 17 through the injection port 3 to cool it first, which is convenient for later demoulding. Then the coolant flows through the cooling pipe 9 and then enters the inner cavity of multiple ejector pins 10 and ejector pins 11. Since the ejector pins 10 and 11 are sleeved inside the mold and in direct contact with the plastic parts, heat transfer can be accelerated and the cooling efficiency of the plastic parts can be improved.

[0030] In the above process, the cooling pipe 9 radiates heat into the heat sink 6 through the multiple groups of heat sinks 19, and at the same time starts the air supply fan 13 to discharge the high-temperature gas in the heat sink 6 from the heat dissipation port 15, thereby ensuring the cooling effect of the coolant.

[0031] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
