The reduction of impact force can also reduce the degree of wear between the various components of the movable mold and the fixed mold, maintain the accuracy and stability of the mold, and reduce problems such as dimensional deviation and poor fit caused by wear.

The cooling processing equipment for the injection molded parts of the electrical base, through the action of the movable mold water inlet device and the fixed mold water inlet device, when the upper punch approaches the lower die, the first magnetic block and the second magnetic block repel each other, the first slider moves to the top of the valve slot, the second slider moves to the bottom of the second valve slot, the second water inlet hole is connected with the first water inlet hole, the fourth water inlet hole is connected with the third water inlet hole, and cooling water passes through; when the upper punch is away from the lower die, the elastic force of the reset spring is greater than the magnetic force of the magnetic block, the slider resets, and due to the action of the limit block, no cooling water will flow out between the first slider and the first water inlet hole and the second slider and the third water inlet hole.

[0017] 3. The cooling processing equipment for the injection molded parts of the electrical base has a heat conducting sheet with a conical structure that is close to the water cooling pipe, and the cooling water flows from the top of the cone to the bottom of the cone. The contact area between the water cooling pipe and the coolant is increased by the heat conducting sheet, thereby accelerating the speed of heat transfer from the injection molded parts to the coolant, and significantly improving the cooling efficiency; because several heat conducting sheets are evenly distributed inside the water cooling pipe, the heat concentrated locally on the injection molded parts can be evenly dispersed to different positions of the water cooling pipe. This can avoid local overheating or overcooling, ensure that the overall temperature of the injection molded parts drops evenly, and reduce defects such as internal stress and deformation caused by uneven temperature. At the same time, the heat conducting sheet helps to balance the temperature of different areas in the water cooling pipe, so that the cooling water can play a more effective cooling role in the entire cooling system, and improve the uniformity and stability of cooling.

[0018] Fourth, the cooling processing equipment for the injection molded parts of the electrical base can slow down the rise of the cooling water temperature through the joint action of the air-cooled heat sink and the movable mold and fixed mold heat dissipation components, thereby making the cooling water cool the mold faster and further improving the cooling speed of the mold. The driving device drives the fan to run, so that wind flow is generated in the mold shell. The air-cooled heat sink is composed of two metal sheets with different angles, and the number is several; the output end of the driving device is directly facing the side of the heat sink with an angle less than 180°, thereby increasing the contact area between the wind and the air-cooled heat sink; the ventilation sheet and the ventilation hole can introduce cooling air, and the ventilation hole serves as a channel for air to enter the air-cooling device, and can introduce relatively low-temperature air from the outside into the device. These cooling air contacts the injection molded parts and the water-cooling pipes, and takes away the heat of the injection molded parts and the water-cooling pipes through heat exchange, thereby achieving the purpose of cooling.

The movable mold heat-conducting sheet 442 is evenly distributed in the first water-cooling tube 441, and the movable mold heat-conducting sheet 442 is in the shape of a quarter cone. The movable mold water baffle 443 is fixedly installed in the interior of the first water-cooling tube 441, and is located at the exact center of the movable mold water inlet device 45 and the movable mold water outlet pipe 444. The second water-cooling tube 541 has the same structure as the first water-cooling tube 441, and has a fan-shaped cross-section. Due to the effect of the water baffle, the cold cutting water flows from the top of the cone to the bottom of the cone, which increases the contact area between the water-cooling tube and the cooling water, thereby accelerating the speed at which heat is transferred from the injection molded part to the coolant, and significantly improving the cooling efficiency. The outlet pipe is fixedly installed on the outer surface of the water-cooling tube, and the outlet pipe is close to the water inlet device. The cooling water flows around the water-cooling tube for one circle and is discharged from the outlet pipe.

[0029] At the same time, the first motor 431 and the second motor 531 respectively drive the first fan 433 and the second fan 533 to operate, so that wind flow is generated in the mold shell. A single air-cooled heat sink 9 is composed of two metal sheets at different angles. The number of air-cooled heat sinks 9 in the movable mold heat dissipation assembly 4 and the fixed mold heat dissipation assembly 5 is eighteen. The air-cooled heat sink 9 increases the contact area between the wind and the heat sink; the ventilation sheets and ventilation holes can introduce cooling air. The ventilation holes serve as channels for air to enter the movable mold heat dissipation assembly 4 and the fixed mold heat dissipation assembly 5, and can introduce relatively low-temperature air from the outside into the interior of the device. The cooling air contacts the injection molded parts and the first water-cooling pipe 441 and the second water-cooling pipe 541, and takes away the heat of the injection molded parts and the water-cooling pipes through heat exchange, thereby further improving the cooling speed of the mold.
