High-performance composite fiber box molding die

Abstract

This utility model relates to a molding die for a high-performance composite fiber box, comprising a die base with a molding limiting groove inside, a fixing frame below the die base, die side plates on both the left and right sides above the die base, a bottom plate below the die side plates, die rib structures inside the die side plates, a main frame above the die side plates, and a die top plate above the main frame. By directly molding the sealing groove during molding, this method ensures the uniformity of the circumferential dimensions of the sealing groove, which is not only aesthetically pleasing but also improves the sealing performance of the product. By controlling the shape and position of the groove through a precision die, the cumulative tolerances or human errors caused by post-processing are avoided, ensuring that the circumferential dimensions of the sealing groove are uniform, reducing local deformation or deviation, thereby improving the overall precision and reliability of the product.

Description

Technical Field

[0001] This utility model relates to the field of molding die technology for high-performance composite fiber boxes, and in particular to molding die for high-performance composite fiber boxes. Background Technology

[0002] High-performance composite fiber housings (such as carbon fiber housings) are lightweight structural components made of carbon fiber reinforced resin matrix composites. They have high strength, corrosion resistance, and multi-functional integration characteristics, and are widely used in new energy vehicles, aerospace, and military equipment. In the production process, molding dies are required for forming. The production dies for high-performance composite fiber housings play a decisive role in the manufacturing process, ensuring product precision, efficiency, and performance optimization.

[0003] Regarding the existing technology patent CN220075641U, which discloses a molding die for a composite material box, the invention includes a mold base frame. A common template dividing the molding die into two molding spaces is vertically mounted in the middle of the mold base frame. Molding uprights perpendicular to the common template and the mold base frame are mounted at both ends of the common template. A beveled molding plate is provided at the bottom of one of the molding spaces. The beveled molding plate is connected to the mold base frame via a pressure block. The common template, the beveled molding plate, and part of the molding uprights form a beveled box molding die, and the common template, mold base frame, and part of the molding uprights form a right-angle box molding die. This solution combines the right-angle box molding die and the beveled box molding die into the same molding die, allowing two boxes to be simultaneously placed in an autoclave for molding, thus shortening the production cycle and improving production efficiency.

[0004] However, existing high-performance composite fiber box molding dies cannot form the geometric structure of the sealing groove in one go. This feature needs to be added through subsequent processing. Moreover, human error can occur during this subsequent operation, resulting in local deformation or deviation, which reduces the overall precision and reliability of the product. In addition, the product surface needs to be treated twice, which reduces the smoothness of the groove edge and the overall appearance integrity, resulting in defects in the product, affecting its aesthetics, and thus reducing the sealing effect of the box. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a molding die for high-performance composite fiber boxes, which has the advantage of one-time molding. This solves the problem that existing molding dies for high-performance composite fiber boxes cannot form the geometric structure of the sealing groove in one go, requiring subsequent processing to add this feature, which can lead to human error, resulting in local deformation or deviation, and thus reducing the overall precision and reliability of the product.

[0006] The technical solution of this utility model is as follows: a molding die for a high-performance composite fiber box includes a die base, a molding limiting groove is provided inside the die base, a fixing frame is provided below the die base, die side plates are provided on the left and right sides above the die base, a bottom plate is provided below the die side plates, a die rib structure is provided inside the die side plates, a main frame is provided above the die side plates, and a die top plate is provided above the main frame.

[0007] Furthermore, fasteners, including fastening bolts, are provided between the mold base and the base plate, and the mold base and the base plate are connected and fixed by fastening bolts.

[0008] Furthermore, the mold rib structure is located between the mold base and the mold upper plate, and on the surface of the main frame, to enhance structural stability.

[0009] Furthermore, longitudinal ribs are fixedly connected to the outer surface of the mold side plates. The longitudinal ribs and the mold side plates are an integrated structure to ensure the strength of the box body rib area.

[0010] Furthermore, the forming limiting groove is set on the inner side of the mold side plate and the mold top plate, and the main frame surrounds the outer side of the mold base, the mold top plate and the mold side plate to form an overall frame structure, which is used to improve the strength of the mold.

[0011] Furthermore, the mold rib structure consists of multiple reinforcing ribs arranged along the connection direction between the mold base and the mold upper plate. The reinforcing ribs are fixed to the mold base and the mold upper plate by welding or bolts to enhance the strength of the mold.

[0012] Furthermore, the mold side plate is divided into multiple areas for fixed molding. This molding mold structure can ensure the maximum continuity during the carbon fiber laying process and improve the structural strength of the product's reinforcing area.

[0013] The beneficial effects of this utility model are: The molding die for this high-performance composite fiber box directly shapes and controls the shape and position of the groove through precision molding, avoiding the accumulation of tolerances or human error caused by post-processing. This ensures that the sealing groove has uniform dimensional height in the circumferential direction, reducing local deformation or deviation, thereby improving the overall accuracy and reliability of the product. One-time molding reduces the need for secondary processing of the product surface, maintaining the smoothness of the groove edges and the integrity of the overall appearance, making the product surface more uniform and flawless. The circumferential dimensional consistency directly reduces potential leakage points, because the uniform distribution of the sealing groove ensures that the sealing material can fit tightly and does not fail under pressure or environmental changes. At the same time, the dimensional accuracy optimizes the pressure distribution of the sealing contact surface, enhancing the anti-permeability. Attached Figure Description
