The first set includes a body and a first mold structure, the first mold structure is disposed on a surface of the body. The second mold includes a movable portion, a first pushing mechanism, a valve and a second pushing mechanism. A second mold structure of the movable portion is combined with the first mold structure to form an accommodating space. The first pushing mechanism is connected to the movable portion for moving the movable portion, so as to combine the second mold structure with the first mold structure. The valve is disposed on the second mold structure for injecting plastic into the accommodating space. The second pushing mechanism is connected to the pushing component. The second pushing mechanism drives the pushing component to pierce through the movable portion, to move the modeled plastic out of the accommodating space. ## Claims ### Claim 1 A modeling apparatus comprising: a first set, the first set comprising: a body; and a first mold structure disposed on a surface of the body; and a second set, the first set being movably disposed on the second set, the second set comprising: a movable portion, the movable portion comprising a second mold structure, the second mold structure being combined with the first mold structure to form an accommodating space; a first pushing mechanism connected to the movable portion, the movable portion being moved by the first pushing mechanism to combine the second mold structure with the first mold structure; a valve disposed on the second mold structure for injecting plastic into the accommodating space; and a second pushing mechanism for pushing the plastic out of the accommodating space. ### Claim 2 (depends on 1) The modeling apparatus of claim 1, wherein the first set further comprises: a conveyer disposed on the body, a thin film being transmitted by the conveyer to cover the first mold structure; a clamper disposed on the body for clamping the thin film; and an extractor disposed on the body for extracting gaseous matter between the first mold structure and the thin film. ### Claim 3 (depends on 1) The modeling apparatus of claim 1, wherein the second pushing mechanism comprises: a pushing component movably passing through the movable portion, the pushing component pushing the plastic to move out of the accommodating space; and a driving unit connected to the pushing component, the driving unit driving the pushing component to pass through the movable portion. ### Claim 4 (depends on 3) The modeling apparatus of claim 3, wherein the first pushing mechanism and the driving unit are compression cylinders. ### Claim 5 (depends on 1) The modeling apparatus of claim 1, wherein the first set further comprises a guiding slot formed on the body, the second set further comprises a guiding bar movable inserting into the guiding slot, and the movable portion moves relative to the guiding bar. ### Claim 6 (depends on 1) The modeling apparatus of claim 1, wherein the first set moves the movable portion relative to the guiding bar after the plastic is injected into the accommodating space, so as to compress the accommodating space to model the plastic. ### Claim 7 (depends on 3) The modeling apparatus of claim 3, wherein the pushing component is a thimble or a taper pin. ### Claim 8 (depends on 3) The modeling apparatus of claim 3, wherein the second set further comprises: a bridging base whereon the first pushing mechanism and the guiding bar are disposed, the first pushing mechanism moving the movable portion relative to the bridging base. ### Claim 9 (depends on 8) The modeling apparatus of claim 8, wherein the second set further comprises: a compression block disposed between the bridging base and the movable portion, the valve and the pushing component passing through the compression block. ### Claim 10 (depends on 9) The modeling apparatus of claim 9, wherein the first pushing mechanism moves the movable portion relative to the compression block to separate the movable portion from the bridging base when pressure of the first pushing mechanism is increased, and the movable portion moves toward the compression block by the body to be close to the bridging base when the pressure of the first pushing mechanism is decreased. ### Claim 11 (depends on 9) The modeling apparatus of claim 9, wherein the second set further comprise: a foundation whereon the driving unit and the pushing component are disposed, the driving unit moving the pushing component relative to the bridging base and the compression block. ### Claim 12 (depends on 11) The modeling apparatus of claim 11, wherein the second set further comprises: a constraining slot formed on the bridging base; and a constraining bar disposed on the foundation, the constraining bar movably inserting into the constraining slot. ### Claim 13 (depends on 8) The modeling apparatus of claim 8, wherein the second set further comprises: a measurement device disposed on the bridging base, the measurement device measuring a movement distance of the movable portion relative to the bridging base. ### Claim 14 (depends on 2) The modeling apparatus of claim 2, wherein decoration ink is disposed on the thin film, the decoration ink is transferred onto the plastic when the plastic is injected into the accommodating space. ### Claim 15 An operation method of a modeling apparatus, the operation method comprising: driving a first set to move close to a second set; combining a first mold structure with a second mold structure to form an accommodating space; injecting plastic into the accommodating space; driving a first pushing mechanism to compress the accommodating space; and utilizing a second pushing mechanism to move the plastic out of the accommodating space. ### Claim 16 (depends on 15) The operation method of claim 15, further comprising: moving a movable portion relative to a guiding bar to combine the first mold structure with the second mold structure. ### Claim 17 (depends on 15) The operation method of claim 15, wherein driving the first pushing mechanism to compress the accommodating space comprises: decreasing pressure of the first pushing mechanism to model the plastic by compression of the accommodating space. ### Claim 18 (depends on 15) The operation method of claim 15, further comprising: transmitting a thin film;
