Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] Such as figure 1 , figure 2 As shown, the traditional FRP elbow mold is an expansive overall structure, including the elbow mold body 1 and the rotating support rod 2. There is an arc seam b=10~20mm wide on the inner arc surface of the elbow mold body 1. Stuff the expansion strips between the seams 3.

[0017] When demolding, first take off the expansion strip 3 in the arc seam, make the mold shrink, and then take off the product.

[0018] Due to the large contact surface between the mold and the product, it is often difficult to demould.

[0019] When the two ends are sockets with larger diameters, the mold of the overall structure cannot be demoulded, and it needs to be molded separately before hand lay-up butt joint.

[0020] Such as image 3 As shown, the present invention includes an elbow mold body 1, a rotating support rod 2, and two pieces of mold ...

Abstract

The invention provides a split-type elbow mold which comprises an elbow mold body and rotating supporting rods, wherein the elbow mold body comprises an outer-piece mold, two inner-piece molds and two sectional elbow molds, wherein the sectional elbow molds are positioned at the two ends of the mold body; the arc surface of the outer-piece mold is connected with the outer side faces of the sectional elbow molds to form an outer side wall of the mold body, and the two inner-piece molds are symmetrically arranged; the arc surfaces of the inner-piece molds are connected with the inner side faces of the sectional elbow molds to form an inner side wall of the mold body; the outer-piece mold, the inner-piece molds and the sectional elbow molds are connected by concave and convex positioning modules, and the rotating supporting rods are respectively and fixedly arranged at the two ends of the elbow mold body and positioned on an extension line of a rotating central line of the elbow mold body. The split-type elbow mold provided by the invention has the advantages that the demoulding is convenient, and the production efficiency is improved; products can be integrally molded; the mold is light to facilitate carrying and assembling.

Description

technical field [0001] The invention relates to a split type elbow mold. Background technique [0002] The traditional FRP elbow mold is an inflatable overall structure. There are arc seams with a width of b=10~20mm on the inner arc surface of the elbow, and expansion strips are filled between the arc seams. [0003] When demolding, first remove the expansion strips in the arc seam to make the mold shrink, and then take off the product. [0004] Due to the large contact surface between the mold and the product, it is often difficult to demould. [0005] When the two ends of the product are sockets with large diameters, the overall structure mold cannot be demoulded, and it needs to be molded separately before hand lay-up butt joint. Contents of the invention [0006] The technical problem to be solved by the invention is that it is difficult to demould the traditional FRP elbow mold. When both ends are sockets with larger diameters, the whole mold cannot be demoulded, an...
