They ensure that the cooling system can accurately control the flow direction and flow rate of the coolant, thereby effectively managing the temperature of the battery pack, motor, and other electrical components. Figure 2 For a valve used in a water pump cooling system, when the valve is injection-molded, since there are several holes inside the valve, after the moving mold is opened during demolding, the core part of each mold needs to be retracted, and vice versa, it also needs to be advanced separately during mold closing. The operation is rather cumbersome, and the production efficiency is low. At the same time, most of the cooling after molding is set around the product, and the internal structure of the valve cools slowly, increasing the cooling time and reducing the production efficiency, making it inconvenient to use.

[0051] As Figure 7 , Figure 10 , Figure 11 shown, inside the core cover 201, there is an outer cooling pipe surrounding the inner wall in a circle.

On the two first connecting pipes 205, there are respectively a first water inlet pipe 206 and a first water outlet pipe 207 passing through the movable mold 2;

[0052] As Figures 16 - 20 shown, on both side walls of the moving box 102, there are respectively a second water inlet pipe 105 and a second water outlet pipe 106.

The inlet end of the fourth connecting pipe 111 is connected with the side of the upper cooling cavity 107 away from the second connecting pipe 109.

[0053] When the utility model works, it includes the following steps:

[0054] Step 1: The moving mold 2 is closed with the fixed mold 1. Insert the lower locking rod 702 into the perforation 704, push the circular snap ring 706 into the arc-shaped card slot on the upper locking rod 703, and fix the lower locking rod 702 to the fixed mold 1 with bolts to lock the fixed mold 1 and the moving mold 2.

[0055] Step 2: The injection nozzle injects glue into the glue inlet cup 601. The glue flows through the glue inlet pipe 602 into the distribution plate 603 and then is distributed into the injection pipes 604 to start injecting glue into the valve forming cavity.

[0056] Step 3: After the injection is completed, cooling starts. Cooling water enters through the first water inlet pipe 206 and then flows in the direction of one first connecting pipe 205, the outer cooling pipe, the other first connecting pipe 205, and the first water outlet pipe 207 in sequence, and then returns to the cooling device to complete a cycle, so that the cooling water circulates in the outer cooling pipe to initially cool the valve product. At the same time, cooling water enters through the second water inlet pipe 105 and then enters one side of the lower cooling cavity 7 through the third connecting pipe 110. The cooling water bypasses the partition 108 and enters the other side of the cooling cavity 7, then enters one side of the upper cooling cavity 7 through the second connecting pipe 109, continues to bypass the partition 108 and enters the other side of the cooling cavity 7, and then enters the second water outlet pipe 106 through the fourth connecting pipe 111, and then returns to the cooling device to complete a cycle, so that the cooling water circulates in the two cooling cavities 107 to quickly cool the valve product.

[0057] Step 4: After the product is formed, the mold is opened. The moving mold 2 moves upward driven by the movable crossbeam of the injection molding machine. During mold opening, it is limited and guided by the limit rod 801. During the mold opening process, the inclined rod 901 and the stopper 902 move upward with the moving mold 2. At this time, the moving box 102 drives the mold core box 103 to retreat along the chute 101, and the mold core box 103 is separated from the formed product.

[0058] Step 5: Start the ejection mechanism 5. The ejector rod 502 moves upward to eject the formed product, and then use the corresponding manipulator to take the product away from the mold opening gap.

[0059] When the present utility model injects the valve, the mold opening and closing are accurate, and the mold core box 103 can move forward and backward with the lifting of the moving mold 2. The product demolding is fast and the use is convenient. At the same time, after the product injection is completed, the inside and outside of the product are cooled simultaneously, the cooling is fast, the production efficiency is high, and the use is convenient.

[0061] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features.
