This necessitates the use of sliders, which allow for smooth demolding while simultaneously injecting the side features. However, existing sliders, driven by hydraulic cylinders, lack a corresponding positioning mechanism during mold closing.

At this time, the slider assembly 600 is also located outside the first cavity 410, and then the slider assembly 600 is driven away from the inner module 500 to provide conditions for demolding the injection mold 20.

[0045] Please refer to the attached Figure 4As shown, the injection mold 20 of the present application further includes a first positioning member 800 , which is respectively disposed on the moving module 400 and the slider assembly 600 to form a limit for the slider assembly 600 along the second direction Y.

[0048] Attachment Figure 6 This is a partial cross-sectional view of the injection mold 20 in Example 2. Figure 6 As shown, attached Figure 6 The specific structural diagram of the injection mold 20 in the mold-closed state is further shown. The slider assembly 600 of the present application includes a slider body 620 and a first driving member 630. The slider body 620 is located in the first cavity 410. In the mold-closed state, the first limiting surface 440 abuts against the slider body 620 to limit the slider body 620 along the second direction Y. However, in the prior art, the slider body 620 is not disposed in the moving module 400. As a result, when the mold is closed, the extrusion force of the moving module 400 is easily applied to the slider body 620, causing the slider body 620 to retreat.
