[0002] The battery housing is a thin-walled, deep-cavity injection molded part. The distribution and form of the cooling water channels in the injection mold have a significant impact on the product's injection molding process. Currently, the injection molding industry is highly automated, requiring a simple mold installation process. To facilitate installation, molds often use water collectors, which require relatively concentrated mold water channels. This results in a single cooling area for the mold and prevents it from being adequately cooled. Therefore, a cooling device is required that ensures adequate cooling of the injection mold.

[0014] The cooling mechanism includes a first cooling member, a second cooling member, a plug 1 and a water temperature sensor; the first cooling member and the second cooling member are both arranged inside the injection mold; the long side wall of the injection mold is provided with a short hole 2 along its width direction, and the length of the short hole 2 is less than half the length of the width of the injection mold; the plug 1 is provided at the end of the short hole 2, and the plug 1 blocks the direct connection channel between the short hole 2 and the outside world, and the short hole 2 can only communicate with the outside world through two long holes; a water temperature sensor is provided at the inward end of the plug 1, and the water temperature sensor can sense the temperature of the cooling water in the mold in real time, and control the flux flow rate of the cooling water by the water temperature of the cooling water, thereby ensuring that the cooling water maintains a suitable low temperature in the mold to ensure the cooling effect; the signal output end of the water temperature sensor is connected to the signal input end of the CPU.

[0015] The first cooling part includes a first long hole 3 and a first solenoid valve 4; the short side wall of the injection mold is provided with a first long hole 3 along its length direction, and the axial direction of the first long hole 3 is parallel to the length direction of the injection mold; the length of the first long hole 3 is smaller than the length of the injection mold; the first solenoid valve 4 is provided at the end of the first long hole 3 located on the short side wall, and the first solenoid valve 4 is connected to the high-pressure water source through a hose; the cooling water enters the first long hole 3 after passing through the hose and the solenoid valve 4, and then flows out of the mold through the short hole and the second long hole in turn. During the forward movement, the cooling water takes away the heat of the mold, thereby cooling the mold; the signal input end of the first solenoid valve 4 is connected to the signal output end of the CPU.

[0016] The second cooling part includes a second long hole 5 and a second solenoid valve 6; the short side wall of the injection mold is provided with a second long hole 5 along its length direction, and the axial direction of the second long hole 5 is parallel to the length direction of the injection mold; the length of the second long hole 5 is smaller than the length of the injection mold; the second solenoid valve 6 is provided at the end of the second long hole 5 located on the short side wall, and the second solenoid valve 6 is connected to the discharge pipe through a hose; the signal input end of the second solenoid valve 6 is connected to the signal output end of the CPU; the flow rate of cooling water in the mold is controlled by the cooperation of the first solenoid valve and the second solenoid valve, thereby controlling the cooling effect of the mold.

[0017] The end of the first long hole 3 is connected to the short hole 2, and the end of the first long hole 3 is in contact with the plug 1; the end of the second long hole 5 is connected to the short hole 2; the distance between the first long hole 3 and the second long hole 5 is equal to the distance between the plug 1 and the end of the short hole 2; the cooling water passes through the first long hole, the short hole and the second long hole in sequence. During this process, the cooling water exchanges heat with the mold, thereby taking away the heat of the mold.

[0018] A screw rod 7 is additionally provided; the screw rod 7 is inserted into the first long hole 3 and the second long hole 5; the screw rod 7 is in close contact with the inner walls of the first long hole 3 and the second long hole 5; the presence of the screw rod increases the residence time of the cooling water in the hole, thereby more fully allowing the cooling water to exchange heat with the mold. In addition, the screw rod 7 is in close contact with the mold, and the screw rod 7 also exchanges heat with the mold, and the cooling water then takes away the heat of the screw rod, which further improves the cooling speed of the mold.

[0019] The model of the CPU module in this utility model is 87C196KC.

[0020] Principle of use: When the mold needs to be cooled, the water source is turned on and the cooling water enters the inner hole of the mold for heat absorption treatment; during this process, the water temperature sensor monitors the cooling water temperature in the hole in real time. Once the water temperature is found to be too high, the first solenoid valve and the second solenoid valve are controlled to increase the water flow rate and accelerate the flow of water, so that the cooling water with low temperature quickly replaces the cooling water with higher temperature in the hole. When the cooling water temperature in the hole is within a reasonable range, the solenoid valve does not operate.
