A rotary demoulding mechanism for a building block toy injection mold

Abstract

The invention relates to the technical field of toy mold structures, in particular to a rotary demoulding mechanism for a building block toy injection mold. A concave template is fixed on the fixed plate of the fixed mold; a push plate guide column is fixed between the fixed plate of the movable mold and the bottom plate; The sliding connection between the plate guide column and the push-out plate; the outer body of the sliding sleeve matches the guide hole; the sliding sleeve is embedded outside the guide hole; the inner side wall of the guide hole is provided with an opening slot; the other end of the slider passes through the opening slot and connects with the The sliding sleeve is rotationally connected; the screw rod is threadedly connected to the threaded sleeve; the threaded sleeve is rotationally connected to the rotating seat; the rotating seat is hinged to the connecting seat; and the connecting seat is rotationally connected to the push-out plate. When using the present invention, the initial angle of the mold core can be adjusted in this structure to prevent dislocation after the building blocks are spliced, and the rotational speed of the mold core can be adjusted to match the pushing speed of the push plate, so that the rotation of the mold core and the push plate The same power mechanism is used for the pushing action, which reduces the power cost.

[0002] Toy building blocks are used to develop children's brains, and the connection methods include pin-hole connection, turnbuckle connection and threaded connection; when building blocks with buckles or internal threads are automatically removed from the mold, they are removed by using a push plate combined with a rotating mold core However, because the structure that drives the rotation of the mold core is generally connected by gears, although the space required for the gear connection is small, an external power device is required, and the speed of the gear must match the speed of the push plate. Once the gear-connected mold core is positioned Finally, the angle of the internal thread cannot be adjusted, otherwise the building blocks will be pushed down; and some require high precision for the position of the starting point of the thread, otherwise the building blocks will be dislocated after splicing
