Embodiment 2
[0035] Embodiment two, such as figure 1 with figure 2 Shown, a kind of injection molding method of the injection mold without draft, comprises the following steps:
[0036] a. Mold closing: make the movable mold core 4 and the fixed mold cavity 3 close the mold, that is, for the product with the straight extension position, the straight extension movable mold core 4 and the straight extension fixed mold cavity 3 matching the straight extension position are set, and then the straight extension movable mold Core 4 and straight stretch fixed mold cavity 3 are closed;
[0037] b. Glue injection: inject glue into the mold cavity after mold closing, that is, inject glue into the mold cavity after the mold closing of the straight-stretching movable mold core 4 and the straight-stretch fixed mold cavity 3;
[0038] c. Heating: While injecting glue into the mold cavity after closing the mold, inject steam into the fixed mold cavity 3 and the movable mold core 4 to heat rapidly, and ...
