Abstract
A device for extracting the mold core and a mold assembly using the same are disclosed. The extracting device comprises a first gear, a plurality of first racks and a plurality of transmission assemblies, wherein the transmission assemblies and the corresponding first racks are spaced apart along the periphery of the first gear such that each transmission assembly is located between the first gear and first racks. The rotating motion of the first gear is transformed into a reciprocating motion of each of the first racks from a first position to a second position.
Claims8
A mold assembly, comprising:
- a base, having a plurality of receiving spaces and a plurality of slots, wherein the receiving spaces being associated with the slots are disposed on the base and spaced apart from each other;
- a device for extracting a mold core comprising;
- a first gear;
- a driving apparatus driving the first gear to rotate;
- a plurality of first racks;
- and
- a plurality of transmission assemblies, which are spaced apart from each other along a periphery of the first gear, and disposed between the periphery of the first gear and the first racks, respectively, so as to transform a rotating motion of the first gear to a reciprocating motion of each of the first racks from a first position to a second position, each of the transmission assemblies comprising:
- a vertical extension shaft, having a first end and a second end opposite to the first end, the first end connecting to the second gear;
- and
- a third gear, disposed on the second end of the vertical extension shaft, the third gear engaging one of the first racks
- wherein each of the first racks and each of the third gears are received in each of the slots and each of the receiving spaces, respectively;
- a plurality of embedded strips, disposed on two opposite sides defining the slot, and each of the embedded strips is detachable from the respective slot thereof:
- and
- a plurality of sleeves, disposed on the receiving spaces respectively, and each of the sleeves is detachable from the respective space thereof.
