Specifically, the plunger holes may be integrally formed in the movable mold half section 11/the fixed mold half section 21 (not shown); in addition, the injection hole 600 may also be partially opened on a certain movable mold half section 11, and correspondingly the other half is opened on the fixed mold half section 21 corresponding to the movable mold half section 11, for example, half of the injection hole 600 is opened on the third movable mold section 113, and the other half is opened on the third fixed mold section 213, as shown in fig. 4 and 6, when the movable mold assembly 10 is closed with the fixed mold assembly 20, the injection hole 600 is closed synchronously, as shown in fig. 1; therefore, when the movable die assembly 10 is separated from the fixed die assembly 20, the hole wall of the material injection hole 600 is exposed, so that residual raw materials in the material injection hole 600 can be removed, and the material injection hole 600 is prevented from being blocked.

In another embodiment of the present invention, as shown in fig. 4 and 7, the side of each movable mold segment 11 facing away from the working surface of the movable mold segment is recessed to form a movable mold hollow-out groove 115, and the side of each stationary mold segment 21 facing away from the working surface 22 of the stationary mold segment is recessed to form a stationary mold hollow-out groove 215, so as to reduce the overall weight of the mold; in addition, during injection molding, the arrangement of the movable mold hollow-out groove 115 and the fixed mold hollow-out groove 215 is also beneficial to heat dissipation of a product during molding, and the condensation molding time of the product is shortened.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
