AI Technical Summary
Technical Problem
During the forming process of the carbon fiber shell, the resin accumulates excessively on the upper surface, resulting in uneven distribution of the resin and affecting the final forming quality.
Method used
The split-type concave die design is adopted, and the batch downward movement of the lift seat, frame side die and column top die is avoided from excessive accumulation of resin on the upper surface of the carbon fiber shell, and uniform heating and cooling are achieved through molds made of high thermal conductivity materials.
Benefits of technology
The uniform distribution of resin on the upper surface and sides of the carbon fiber shell is achieved, the molding quality is improved, and the mold release process is simplified by accelerating cooling and curing.

Abstract
The invention provides a carbon fiber shell forming device and method for musical instrument production, and belongs to the technical field of musical instrument production and processing.The carbon fiber shell forming device comprises a male die, a female die installed over the male die and a vacuumizing pipe arranged at the bottom of the male die in a penetrating mode; the female die is composed of a lifting seat, a frame type side die and a column type top die, the lifting seat is vertically and slidably connected to the position over the male die, the frame type side die and the column type top die are vertically and slidably connected to the interior of the lifting seat through elastic pieces, and an inner cavity of the frame type side die is composed of a sliding sleeve cavity matched with the column type top die and a side die cavity matched with the carbon fiber shell; an extrusion gap is reserved between the edge of the bottom end of the sliding sleeve cavity and the edge of the corner of the inner top wall of the side die cavity; a locking piece matched with the frame type side mold is arranged on the lifting seat; the probability of excessive accumulation of the resin on the upper surface of the carbon fiber shell can be reduced.
