DETAILED DESCRIPTION

[0020] The following describes the invention of the present invention in detail by way of examples in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Example

[0021] like Figures 1 to 2As shown, the present invention discloses a demolding device for glass fiber reinforced plastic pipe fittings, comprising a base 1, to which a lifting platform 2 and a gearbox 3 are slidably connected. Specifically, the lifting platform 2 is slidably connected within a slide rail 1 9 on the base 1 and is driven by a cylinder 1 10; the gearbox 3 is slidably connected within a slide rail 2 11 on the base 1 and is driven by a cylinder 2 12; both cylinders 10 and 12 are fixedly connected to the base 1. In this embodiment, the sliding arrangement of the lifting platform 2 facilitates demolding of glass fiber reinforced plastic pipe fittings of different specifications, and the sliding arrangement of the gearbox 3 facilitates driving the mold to remove the pipe fittings.

[0022] A clamping frame 4 is provided on the lifting platform 2, and a clamping tool 5 is provided between the clamping frame 4 and the lifting platform 2; the clamping tool 5 includes a clamping upper part 51 and a clamping lower part 52, and rubber pads are provided on the opposite surfaces of the clamping upper part 51 and the clamping lower part 52 to prevent the tool from directly contacting the pipe fittings and clamping the pipe fittings; the clamping lower part 52 is fixedly connected to the lifting platform 2, and the clamping upper part 51 is fixedly connected to the piston rod of the cylinder three 13, and the cylinder three 13 is fixedly connected to the clamping frame 4, which is conducive to clamping pipe fittings of different diameters.
