9. The glass fiber reinforced plastic product demolding tool as claimed in any one of claims 1 to 8, wherein: the demolding method comprises the following steps:
the first step is as follows: locking of the knocking demoulding device: firstly, the glass fiber reinforced plastic product demolding tool is installed on an external rotating device, and the glass fiber reinforced plastic product demolding tool can be driven to rotate to a proper knocking position through the rotation of the external rotating device;
the second step is that: replacement of the rapping hammer (44): the knocking hammer (44) is replaced according to the requirement by hammering the appearance structure of the glass fiber reinforced plastic cylinder, so that the knocking hammer (44) can stably knock on the glass fiber reinforced plastic cylinder;
the third step: hammering the glass fiber reinforced plastic cylinder: the hydraulic cylinder (3) is controlled to do extension movement, the follower rod (45) can be contacted with the left end of the guide frame (472), the inclined structure of the left end of the guide frame (472) enables the position of the follower rod (45) to be lifted, when the follower rod (45) moves to the top of the guide frame (472), the movable baffle (473) is pushed to move rightwards under the blocking action of the stop block (474), so that the movable baffle (473) moves to the right side of the guide frame (472) and the stop block (474) automatically falls under the action of gravity, so that the follower rod (45) can move to the right side of the movable baffle (473) smoothly, at the moment, the right side of the movable baffle (473) is positioned at the right side of the guide frame (472), when the follower rod (45) is separated from the guide frame (472), the movable baffle (473) can return to the initial position under the action of the return spring (476), meanwhile, the knocking hammer (44) performs hammering action under the action of the restoring force of the knocking spring (43);
the fourth step: and (3) circularly hammering the glass fiber reinforced plastic cylinder: the telescopic motion of the hydraulic cylinder (3) can drive the knocking hammer (44) to do circulating hammering action;
the fifth step: and (3) separating a die opening: when the knocking hammer (44) performs hammering action on the glass fiber reinforced plastic cylinder, a round hole opener is manually inserted into a joint of the mold and a product, so that the glass fiber reinforced plastic cylinder at the knocking part can be separated from the mold;
and a sixth step: and (3) completely separating the glass fiber reinforced plastic cylinder: the glass fiber reinforced plastic cylinder can be separated from the mold by controlling the external rotating device to rotate and repeating the knocking action, so that the demolding action of the glass fiber reinforced plastic cylinder is completed.
