Detailed ways

In order to describe the technical solutions of the present invention more clearly and completely, the present invention is further described below with reference to the accompanying drawings.

Please refer to FIG. 1 to FIG. 3, the utility model proposes a floating mold, the floating mold includes: a movable mold part 1, a fixed mold part 2, a row seat 4, an inclined guide post 22 and a movable insert 3, The movable mold part 1 includes a movable mold core 11 , the fixed mold part 2 includes a fixed mold core 21 , and the movable mold core 11 and the fixed mold core 21 are closed to form a accommodating cavity 5 , and the movable insert 3 It is movably connected with the movable mold part 1 and partially accommodated in the accommodating cavity 5; connection; the positioning seat 4 is provided with a positioning slot 41, the movable insert 3 is provided with a positioning hole 31, and the inclined guide post 22 penetrates the positioning hole 31 and the positioning slot 41. When the mold is opened When the slanted guide post 22 drives the movable insert 3 to move; the movable insert 3 is provided with a convex portion 32 , the travel seat 4 is provided with a chute 43 , and the convex portion 32 is accommodated in the so that the movable insert 3 can slide in the chute 43; the travel seat 4 is provided with a limit column 44, and the limit column 44 restricts the sliding of the movable insert 3. scope.

In this embodiment, the movable mold core 11 and the fixed mold core 21 are filmed together to form an accommodating cavity 5 , and the movable insert 3 is partially accommodated in the accommodating cavity 5 to form a produced product model for injection molding. The mold is formed. When the injection molding is completed, the mold is opened after the product is formed. The positioning hole 31 matches the inclination of the inclined guide column 22 , the fixed mold part 2 rises vertically, and the fixed mold core 21 is Part of the product is demolded. During the rising process of the fixed mold part 2, the inclined guide post 22 vertically rises through the same inclination as the positioning hole 31, thereby driving the The movable insert 3 moves, the movable insert 3 moves in the chute 43, and the limit post 44 limits the sliding range of the movable insert 3 to prevent the movable insert 3 from slipping off. The insert 3 stops sliding after touching the limit post 44.
