Detailed Description

As shown in fig. 1 to 4, an injection mold facilitating product replacement processing comprises a movable mold 1 and a fixed mold 2.

And a plurality of assembling standard cavity groups 3 corresponding to the positions are arranged on the contact surfaces of the movable mold 1 and the fixed mold 2. In the present illustration, only two sets of standard chamber sets 3 are shown, and in practice, three, four or more sets may be provided according to the product processing requirements.

The set of assembly standard cavities 3 of each set is constituted by an upper standard cavity 3a and a lower standard cavity 3 b.

The upper standard cavity 3a is arranged on the bottom surface of the movable mould 1, a movable mould insert 4 is installed in the upper standard cavity 3a, and a core 41 is arranged on the movable mould insert 4. In order to facilitate the installation and positioning of the movable die insert 4, the upper standard cavity 3a is provided with an assembly inclined surface 3a1, and during assembly, only the corresponding inclined surface of the movable die insert 4 needs to be aligned with the assembly inclined surface 3a 1.

The periphery of the movable die insert 4 is provided with a connecting outer edge 42, the connecting outer edge 42 is provided with a plurality of positioning holes 421 at intervals along the circumferential direction, and each positioning hole 421 is provided with a screw 422 to fix the movable die insert 4 in the upper standard cavity 3 a. The locking structure of the screw 422 is a detachable structure, which can facilitate the detachment, replacement and maintenance of the movable die insert 4 in the later period, so as to meet the replacement requirement of the movable die insert 4 during the processing of different products.
