Description

Technical Field

[0001] The utility model relates to the technical field of composite material molding, in particular to a composite material pipe product anti-clamping molding tool. Background Art

[0002] Composite materials are widely used in various industries, including aerospace, construction, automotive, energy, infrastructure, marine, military, sports and entertainment industries.

[0003] Many parts are made by laying and curing composite materials. For example, when composite pipe products are being formed, the composite materials are first laid on the core mold; then the core mold and the laid pipe product are hoisted to the lower mold using a gantry truck, and then the upper mold is hoisted to the top of the lower mold using a gantry truck. The position is adjusted and the mold is dropped steadily in the vertical direction. After the upper mold falls to the bottom, it is tightened with fastening bolts to complete the mold closing of the product.

[0004] However, in this molding process, since the upper and lower molds are split structures, the closed gap between the two is prone to material clamping, which affects the appearance and internal quality of the final product, resulting in a low pass rate and increased manufacturing costs.

[0007] On the basis of the above scheme and as a preferred scheme of the above scheme: the inner side of the gasket is flush with the inner wall of the forming groove, and the gasket is an arc-shaped structure.

[0008] On the basis of the above scheme and as a preferred scheme of the above scheme: the recessed portion on the forming groove is arranged along the axial direction, and the length is consistent with the length of the forming groove.

[0009] On the basis of the above scheme and as a preferred scheme of the above scheme: the width of the recessed portion on the forming groove is 25 mm, and the depth of the recessed portion is 0.1 mm.

[0011] On the basis of the above solution and as a preferred solution of the above solution: the material of the gasket is spring steel.

[0012] When composite pipe products are being formed;

[0013] 1) Complete the laying of composite materials on the core mold;

[0014] 2) Use a gantry truck to hoist the core mold together with the laid-out pipe products onto the lower mold, and place the gaskets in the depressions on both sides of the molding groove of the lower mold;

[0015] 3) Use a gantry truck to hoist the upper mold to the top of the lower mold, adjust the position, and drop it steadily in the vertical direction. At this time, the concave portions on both sides of the molding groove of the upper mold are located outside the gasket, so that the gasket covers the joint of the upper mold and the lower mold;

[0016] 4) After the upper mold falls to the bottom, use the fastening bolts to fasten the upper and lower molds together to complete the mold closing of the product.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. A gasket is set on the inner side of the joint of the upper and lower molds to cover the mold gap, which fundamentally solves the risk of material clamping in the mold closing process of composite pipe products, ensures the appearance and internal quality of the product, improves production efficiency and pass rate, and reduces the manufacturing risk of composite pipe products.

[0019] 2. Process the concave part on the inner side of the forming groove of the upper and lower molds so that the gasket is flush with the inner wall of the forming groove to ensure the appearance quality of the composite pipe products.

[0020] 3. The gasket is made of spring steel with certain flexibility and plasticity to avoid the problem of gasket getting stuck during mold closing and demoulding, thereby increasing applicability. BRIEF DESCRIPTION OF THE DRAWINGS
