Rotary demoulding mechanism of injection mold for building block toys

Abstract

The invention relates to the technical field of toy mold structures, in particular to a rotary demoulding mechanism of an injection mold for building block toys. A concave die plate is fixed to a fixed die fixing plate; a push plate guide post is fixed between a movable die fixing plate and a bottom plate; the push plate guide post is in sliding connection with a push plate; the outer body of a sliding sleeve is matched with a guide hole; the sliding sleeve is embedded into the guide hole; an open groove is formed in the inner side wall of the guide hole; the other end of a sliding block passes through the open groove and then is rotatably connected with the sliding sleeve; a screw is in threaded connection with a threaded sleeve; the threaded sleeve is rotatably connected with a rotatingseat; the rotating seat is hinged with a connecting seat; and the connecting seat is rotatably connected with the push plate. When the rotary demoulding mechanism is used, the initial angle of a moldcore can be adjusted in the structure, so that the phenomenon of dislocation after building blocks are spliced is prevented, the rotating speed of the mold core can be matched with the push speed of the push plate after adjustment, and the same power mechanism is used for the rotary motion of the mold core and the push motion of the push plate, so that the power cost is reduced.

[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
