Before injection molding, the male die plate 3 and the female die plate 4 are closed to form the forming cavity 6 between the male die 31 and the female die 41, and then molten plastic is injected into the forming cavity 6 through the pouring port 51. Low pressure and slow injection are adopted during injection molding, and if the injection raw material is smooth and thin, and there is no bubble and silver wire on the surface, the part forming can be started.

[0042] After the molten plastic injection is completed, the cooling liquid is injected into the heat exchange runner 7, so as to quickly take away the heat of the plastic in the forming cavity 6, so that the product is quickly formed. After the positioning frame 8 is cooled and formed, the male die plate 3 and the female die plate 4 are separated, and demolding ejection work is prepared. During ejection, the output end of the driving mechanism applies an upward thrust to the ejector pin bottom plate 21 through the ejection hole 11, the ejector pin bottom plate 21 drives the ejector pin face plate 22 to move upward, and the ejector pin face plate 22 drives the ejector pin 26 to move upward and pass through the ejector pin hole 35. The ejector pin 26 passing through the ejector pin hole 35 ejects the positioning frame 8 from the male die 31, and the driving mechanism is recovered at the same time. Under the action of the elastic force of the spring 25, the ejector pin face plate 22, the ejector pin bottom plate 21 and the corresponding parts all return to the initial position. After ejection, the product is collected, and then the mold is closed, injection molding, ejection and collection are carried out again. After the product is demolded, a suitable cutter is used to cut off the gate and clean the burr.
