A resin-based composite material battery box laying mold for new energy vehicles

Abstract

The invention discloses a resin-based composite material battery box laying mold for new energy vehicles. The mold includes an inner mold, an outer mold and a fastening device. The inner mold includes an inner flanging edge, an inner panel-front, an inner panel-middle, an inner panel-back, a center panel of the inner bottom surface and four corners of the inner bottom surface. The outer mold includes outer plate-front, outer plate-middle, outer plate-rear and outer bottom surface. The fastening device includes a side plate fastening device and an upper and lower fastening device, which are composed of bolts, nuts, side panels and upper and lower panels. The internal and external combination mold designed by the invention can fully guarantee the geometric accuracy and structural accuracy of the battery box; the detachable mold designed by the invention well overcomes the difficult problem of complex demoulding of resin-based composite materials; the openable mold designed by the invention The outer mold overcomes the influence of the concave-convex plane formed by the reinforcement structure of the battery box on the installation of the outer mold.

Description

technical field [0001] The invention relates to a composite material laying molding die, which belongs to the technical field of composite material molding, and in particular to a resin-based composite material battery box laying molding die for new energy vehicles. Background technique [0002] In the field of new energy vehicles, resin-based composite materials are more and more widely used due to their small specific gravity, high specific strength, and fatigue resistance. Composite materials are highly designable and can be prepared into complex structures according to performance requirements Integral components enable the entire component to obtain better service performance. However, complex structural parts often bring great difficulties to the design of forming dies. Whether the die design is reasonable or not directly affects the forming quality and service performance of composite components. [0003] For the battery case of resin-based composite material used in...

AI Technical Summary

Problems solved by technology

[0009] The present invention is aimed at the design of the laying and molding mold for the resin-based composite material battery box, and aims at the lack of relevant mold design references, the difficulty of demolding after the resin-based composite material is cured and formed, the dimensional accuracy and structure of the composite material after laying and forming and curing and forming In order to solve the problems such as difficult to guarantee the accuracy, a battery box mold with simple structure, convenient demoulding, and the ability to guarantee the geometric accuracy and structural accuracy of the battery box was designed.
