[0034] Among them, the jacking device for fiberglass grating includes a mounting base 1 located below the mold, a pair of first sliding seats 2 and second sliding seats 3 respectively arranged on the mounting base 1 and capable of sliding synchronously close to or away from each other along the parallel to the first direction (i.e., Figure 1 the arrow direction in Figure 1-2 ), a lifting seat 4 liftably arranged on the mounting base 1, a first guiding groove 5 and a second guiding groove 6 respectively arranged on the first sliding seat 2 and the second sliding seat 3, a pair of first rotors 7 and second rotors 8 arranged on the lifting seat 4 at intervals along the first direction, and a pair of first driving cylinders 9 and second driving cylinders 10 arranged on the mounting base 1 and respectively used to drive the first sliding seat 2 and the second sliding seat 3 to slide.

The first rotor 7 and the second rotor 8 are respectively arranged in the first guiding groove 5 and the second guiding groove 6. In this embodiment, the first guiding groove 5 and the second guiding groove 6 are respectively inclined upward in the direction away from each other. Through this setting, when the first sliding seat 2 and the second sliding seat 3 slide away from each other relatively, they can cooperate to drive the lifting seat 4 to descend; when the first sliding seat 2 and the second sliding seat 3 slide close to each other relatively, they can cooperate to drive the lifting seat 4 to ascend.

A space is left between the lower surface of the lifting seat 4 and the upper surfaces of the first bottom plate 21 and the second bottom plate 31 to leave a space for the lifting seat 4 to perform lifting movement.

[0043] For a single lifting seat 4, there are a pair of first side plates 22, which are respectively arranged on both sides of the lifting seat 4 perpendicular to the first direction; there are also a pair of second side plates 32, which are respectively arranged on both sides of the lifting seat 4 perpendicular to the first direction.

The first rotor 7 and the second rotor 8 are respectively arranged on the first adjusting bolt 12 and the second adjusting bolt 13 so as to be rotatable around their own axis directions. Through this setting, the leveling of both ends of the lifting seat 4 can be realized, and then the leveling of the top pin upper plate can be realized, so as to facilitate the stable demoulding of the fiberglass grating.

[0045] See Figure 4-5As shown, in this embodiment, a first mounting cylinder 14 coaxial with the first rotor 7 is connected to the bottom of the first adjusting bolt 12, and the first rotor 7 is rotatably disposed in the first mounting cylinder 14 about its own axis; a second mounting cylinder coaxial with the second rotor 8 is connected to the bottom of the second adjusting bolt 13, and the second rotor 8 is rotatably disposed in the second mounting cylinder about its own axis.

In this embodiment, the fixing mechanism 15 includes a pin seat 151 provided on the mounting seat 1, a pin 152 telescopically disposed on the mounting seat 1 along a first direction, and a second driving member 153 for driving the pin 152 to perform telescopic movement. Through this setting, the mold and the mounting seat 1 can be relatively stationary during the jacking operation, so as to better eject the fiberglass grating.

[0048] The working process of this embodiment is specifically described as follows:

[0049] First, the upper plate of the ejector pin is pressed against the lifting seat 4 through the pressing mechanism 11, and the mold is fixed on the mounting seat 1 through the fixing mechanism 15, so that the mold is located above the upper plate of the ejector pin;

[0050] Then, the first driving cylinder 9 and the second driving cylinder 10 synchronously drive the first sliding seat 2 and the second sliding seat 3 to approach each other. Under the cooperation of the first guiding groove 5 and the first rotor 7, and the second guiding groove 6 and the second rotor 8, the lifting seat 4 is driven to rise, and the fiberglass grating in the mold is ejected upward through the upper plate of the ejector pin;

[0051] Finally, the first driving cylinder 9 and the second driving cylinder 10 synchronously drive the first sliding seat 2 and the second sliding seat 3 to move away from each other. Under the cooperation of the first guiding groove 5 and the first rotor 7, and the second guiding groove 6 and the second rotor 8, the lifting seat 4 is driven to drive the upper plate of the ejector pin to descend and reset.
