[0027] Furthermore, a slide groove is provided on the side wall of the mold film frame 1 and corresponds to the side slider 2, wherein the connection mode between the side slider 2 and the slide groove is sliding connection, a connecting hole is provided on the side slider 2 and corresponds to the inclined guide column 3, wherein the matching mode between the inclined guide column 3 and the connecting hole is clearance matching, reserved grooves are provided on both sides of the top block connecting groove 5 and correspond to the movable top block 6, wherein the matching mode between the top block connecting groove 5 and the movable top block 6 is clearance matching, and a connecting hole is provided in the inner cavity of the ejector pin tube 7 and corresponds to the inlay pin 9, wherein the matching mode between the inlay pin 9 and the connecting hole is clearance matching, so that the mold can be used more smoothly;

[0028] In this embodiment, reference Figure 1 , Figure 2 , Figure 3 and Figure 5 The water-cooled temperature control structure 11 includes a heat sink 1101, which is connected to the side wall of the mold film frame 1, and a temperature control sensor 1102 is connected to the side wall of the heat sink 1101. A circulating water cooling pipe 1103 is connected to the inner cavity of the heat sink 1101, and a water outlet connecting pipe 1104 is provided at one end of the circulating water cooling pipe 1103. The water outlet connecting pipe 1104 is connected to the water outlet of the water cooling pipe 10, and a temperature sensor and a controller are provided in the temperature control sensor 1102, wherein the controller is connected to the water pump of the injection molding machine and the connection method is an electrical connection.
