[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figure 1 and Figure 2As shown, a rapid-release injection molding die includes a lower fixed plate 1, a lower mold base 2, and a blanking assembly 6.

An injection cavity 606 is provided at the lower end of the upper mold base 3. The internal dimensions of the limiting slots 602 are adapted to the external dimensions of the limiting vertical rods 603, and the limiting vertical rods 603 are embedded in the bottom mold plate 601 through the limiting slots 602. The ejector pins 604 are vertically distributed with the bottom mold plate 601. The bottom pin plate 601 is fixedly connected to the bottom pin plate 601 by bolts. The external dimensions of the push plate 605 are adapted to the internal dimensions of the injection cavity 606, and the outer side of the push plate 605 is tightly fitted to the inner wall of the injection cavity 606. The limiting vertical rod 603 is fixedly installed on both sides inside the lower mold base 2 by fastening bolts. The bottom pin plate 601 is installed inside the lower mold base 2. At the same time, the internal dimensions of the limiting through grooves 602 opened at the four corners inside the bottom pin plate 601 are adapted to the external dimensions of the limiting vertical rod 603. Thus, the bottom pin plate 601 is fixedly installed inside the lower mold base 2 by the limiting through grooves 602 and the limiting vertical rod 603. The needle plate 601 is installed inside the lower mold base 2 to limit the position of the ejector pin 604. The ejector pin 604 is fixedly installed on the upper end of the bottom needle plate 601. The ejector pin 604 is moved inside the lower mold base 2 by the push rod of the injection molding machine.

The immersion cooler 702 cools the cooling water inside the water tank 701. Simultaneously, the water pump 703 located on the upper left side of the water tank 701, in conjunction with the water supply pipe 704, delivers cooling water to the cooling water pipe 705. The cooling water pipe 705 is then limited and installed inside the lower mold base 2 through the mounting cavity 706. The cooling water inside the cooling water pipe 705 rapidly cools the injection molded part. Next, the limiting vertical rod 603 is fixedly installed on both sides inside the lower mold base 2 by tightening bolts. The bottom pin plate 601 is installed inside the lower mold base 2. At the same time, the limiting through groove 602 is used in conjunction with the limiting vertical rod 603 to limit the installation of the bottom pin plate 601 inside the lower mold base 2. The ejector pin 604 is fixedly installed on the upper end of the bottom pin plate 601. The ejector rod of the injection molding machine pushes the bottom pin plate 601, causing the ejector pin 604 to move in position inside the lower mold base 2. This also drives the pusher plate 605 installed at the front end of the ejector pin 604 to adjust its position inside the injection cavity 606. The pusher plate 605 is used to quickly push the part inside the injection cavity 606 out of the injection cavity 606, thereby completing the rapid demolding and unloading of the part and improving the overall practicality and efficiency of the injection molding mold.
