[0021] The following description is only intended to disclose the present invention so that those skilled in the art can implement it. The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0022] A type of fiberglass flange mold that can be integrally formed, such as Figure 1 It includes a lower mold 1, an upper mold 2 and a demolding ejection assembly 3. The lower mold 1 and the upper mold 2 are preferably made of steel or materials that are not easily deformed by heat, and the flange forming mold is made according to the flange shape dimensions using precision CNC machining equipment.

[0023] like Figure 1 , Figure 2 The lower mold 1 includes a mold cavity 11, a positioning protrusion 15 and a tube 13, and the outer circle of the tube 13 is provided with a fastening thread 14.

[0024] The mold cavity 11 is formed by a bottom wall and an annular side wall. The tube 13 is located at the center of the mold cavity 11. Preferably, the tube 13 is hollow to reduce mold cost and weight. The annular side wall of the lower mold 1 is provided with an overflow groove 12 connected to the mold cavity 11 to discharge excess material and ensure the flatness of the back of the flange. In this embodiment, there are 4 sets of overflow grooves 12, which are evenly distributed around the mold cavity 11.

[0025] The positioning protrusion 15 is used to position the bolt holes of the product. The positioning protrusion 15 adopts a positioning steel ball. A countersunk hole is machined on the bottom wall of the lower mold 1, and the positioning steel ball is installed in the countersunk hole.

[0026] The number of positioning steel balls is set according to the product model.

[0027] The ejection assembly 3 includes ejection bolts. The product is ejected by screwing the ejection bolts into the mold cavity 11. The ejection bolts also serve as bolt holes for positioning the product. Optionally, the end of the ejection bolt used to eject the product is arc-shaped or conical.

[0028] Before molding the fiberglass flange 4, screw the release bolts into the mold cavity 11 so that their ends are aligned with the height of the positioning protrusion 15. Together with the positioning protrusion 15, they serve to position the flange hole of the product. Figure 3 After the fiberglass flange 4 is formed, a groove is formed on the fiberglass flange 4 to facilitate the subsequent processing of bolt holes.

[0029] In this embodiment, the fiberglass flange 4 has eight bolt holes, including four sets of demolding bolts arranged in a cross shape, and four sets of positioning steel balls.

[0030] The upper die 2 comprises a sleeve part 21 and a flange surface pressing part 23, and the inner wall of the sleeve part 21 is provided with a threaded part 22. After the sleeve part 21 is sleeved into the pipe part 13, the lower part between the two is in threaded cooperation and also forms a die cavity, which is used for forming the pipe joint part 41 of the glass steel flange 4. The threaded part 22 cooperates with the fastening thread part 14, so that the flange surface pressing part 23 forms a pre-pressure on the product to be formed, thereby ensuring that the glass steel flange has sufficient compactness and flatness.

[0031] Preferably, as Figure 1 The pipe part 13 is provided with a variable diameter part 16 outside the fastening thread part 14. The diameter of the variable diameter part 16 is smaller than that of the fastening thread part 14, so that the sleeve part 21 can be conveniently and accurately sleeved into the pipe part 13.

[0032] Before the product is formed, the surface of the mold is polished and polished, and after a specific smoothness is formed, a layer of release agent is coated on the surface. The glass steel flange is pasted in the mold by using glass fiber, resin and other materials. The flange and the pipe joint part can be synchronously and cross-laid glass fiber cloth until the thickness of the flange surface and the pipe joint part reaches the design requirement. Finally, after the glass steel flange 4 is solidified and formed in the mold, the product is ejected from the mold by clockwise and symmetrical screwing of the mold bottom demolding bolt.

[0033] Those skilled in the art should understand that the above description and the embodiments of the utility model shown in the drawings are only as examples and do not limit the utility model. The purpose of the utility model has been completely and effectively realized. The function and structural principle of the utility model have been demonstrated and explained in the embodiments.
