[0034] See also Figure 1-Figure 7 The utility model provides a cooling device for an injection mold that can quickly cool down. The inner cavity of the box body 200 is divided into a left chamber and a right chamber by a partition 220. If the temperature on the left side rises, the chamber on the left side is closed by an electric push rod 250, and the conversion component 240 controls the blocking component 230 to open the right chamber, and switches to the right chamber to cool down the lower concave mold 110, so that the lower concave mold 110 can be continuously cooled.

[0035] The cooling device body 001 includes a horizontal plate 100, and a lower die 110 and an upper die 130 are installed at the upper end of the horizontal plate 100. A vertical water groove 112 and a horizontal water groove 113 for cooling water circulation are provided inside the lower die 110, and a plurality of vertical water grooves 112 and horizontal water grooves 113 are provided inside the lower die 110. A water inlet 111 for conveying cooling water to the vertical water groove 112 is provided on one side of the lower die 110, and the water inlet 111, the vertical water groove 112 and the horizontal water groove 113 are connected, and a cavity for conveying cooling water to the interior of the box 200 in cooperation with the water inlet pipe 270 is also provided on the right side of the lower die 110.

[0036] A support frame 120 for supporting the cylinder 131 is fixedly installed on the upper end of the horizontal plate 100. A cylinder 131 for controlling the upper die 130 to move up and down is fixedly installed on the upper end of the upper die 130, and a plurality of guide rods 132 for limiting the upper die 130 are fixedly installed on the upper end of the upper die 130, and a limit block 133 for limiting the guide rod 132 is fixedly installed on the upper end of the guide rod 132. When the upper die 130 cooperates with the lower die 110 to manufacture parts, the cooling water is transported from the inner cavity of the box body 200 to the hole cavity of the water inlet 111 through the water outlet pipe 260, and is transported to the water inlet pipe 270 on the right side of the lower die 110 through the vertical water groove 112 and the horizontal water groove 113, and finally transported back to the inner cavity of the box body 200.

[0037] A cooling box 002 for quickly cooling the mold in cooperation with the cooling device body 001 is installed at the rear end of the cooling device body 001. The cooling box 002 includes a box body 200. A partition 210 is fixedly installed at the front and rear ends of the box body 200, and a water pipe 211 is installed in the middle of the partition 210. The partition 210 divides the inner cavity of the box body 200 into a front cavity, a middle cavity and a rear cavity. The front cavity of the box body 200 is installed with a pump body for facilitating the delivery of coolant. The water pipe 211 is used to connect the middle cavity and the front cavity or to connect the middle cavity and the rear cavity.

[0038] The middle of the box 200 is equipped with a partition 220 for dividing the inner cavity of the box 200, and the two ends of the partition 220 are fixedly installed on the partition 1 210. The partition 220 divides the middle cavity of the box 200 into a left chamber and a right chamber, and the two sides of the partition 220 are fixedly installed with a heat insulation pad 221 for isolating heat. When the coolant in the left chamber of the box 200 rises, the heat is not easily transferred to the right chamber. The left chamber and the right chamber of the box 200 can be installed with a temperature detection device, so that when the temperature reaches a predetermined threshold, the controller controls the electric push rod 250 to start, close the side with a higher temperature, and open the side with a lower temperature.

[0039] The front and rear ends of the box body 200 are equipped with a plugging assembly 230 for opening and closing the pipe mouth of the water pipe 211. There are multiple plugging assemblies 230, and the plugging assembly 230 includes a fixed plate 231. A sealing rubber 232 for cooperating with the water pipe 211 to block the cooling water is fixedly installed on one side of the fixed plate 231 close to the partition 210, so that when the sealing rubber 232 closes the pipe mouth of the water pipe 211, the chamber on the side with a high temperature is closed. A limiting block 233 is fixedly installed on the other side of the fixed plate 231, and a limiting rod 234 for limiting the conversion assembly 240 is installed in the middle of the limiting block 233.

[0040] The middle part of the limiting rod 234 is sleeved with a conversion assembly 240 for controlling the fixed plate 231 to open and close the water pipe 211. The conversion assembly 240 includes a V-shaped rod 241. Both ends of the V-shaped rod 241 are provided with limiting holes 242 for cooperating with the limiting rod 234 to limit the V-shaped rod 241. A rotating shaft 243 is fixedly installed in the middle of the V-shaped rod 241. When the temperature in the left chamber rises, the electric push rod 250 pushes the blocking assembly 230 on the left side of the front cavity. Under the guidance of the V-shaped rod 241, the V-shaped rod 241 drives the front cavity The sealing component 230 on the right is away from the water pipe 211, so that the sealing component 230 opens the right chamber, allowing the coolant with a lower temperature in the right chamber to flow to the front cavity, and is transported to the water outlet pipe 260 through the pump body, and finally transported to the vertical water groove 112 and the horizontal water groove 113 to cool the lower die 110. The conversion component 240 of the rear cavity of the box body 200 controls the sealing component 230 to close the left chamber and open the right chamber, so that the coolant can be transported to the rear cavity of the box body 200 through the water inlet pipe 270 and then to the right chamber.

[0041] An electric push rod 250 for controlling the movement of the fixed disk 231 is fixedly installed in the middle of the fixed disk 231, a water outlet pipe 260 for conveying coolant to the hole cavity of the water inlet 111 is fixedly installed on the left side of the box body 200, and the water outlet pipe 260 is connected to the front cavity of the box body 200, and a water inlet pipe 270 for conveying the coolant inside the lower die 110 to the inside of the box body 200 is installed on the right side of the box body 200, and the water inlet pipe 270 is connected to the rear cavity of the box body 200. A limit assembly 280 for limiting the V-shaped rod 241 is fixedly installed in the middle of the V-shaped rod 241. The limit assembly 280 includes a U-shaped block 281. A slide groove 282 for the rotating shaft 243 to slide is opened in the middle of the U-shaped block 281, so that when the electric push rod 250 pushes the sealing assembly 230 on one side, the rotating shaft 243 slides in the groove cavity of the slide groove 282, and the sealing assembly 230 on the other side opens the water pipe 211 to switch the coolant.

[0042] Based on the above content and the accompanying drawings, those skilled in the art can understand and implement the utility model. In addition, any non-creative modifications made to the utility model by those skilled in the art without making creative work still fall within the scope of protection of the utility model.
