Abstract

The invention relates to the technical field of injection molding, and discloses a novel tray forming mold adopting chemical foaming agent injection molding. The mold comprises a mold core part and a mold cavity part, the mold core part of the mold is provided with four lifters, four core hydraulic pins are arranged at four corners, the mold cavity part is provided with a pop-up slide block, and the side surface is provided with a hydraulic slide block. When the mold core part and the mold cavity part perform hydraulic motion, a model designed by 3D simulation software is subjected to injection molding by using a chemical foaming agent (CBA) to form the novel tray forming mold, a valve gate injection molding system is arranged in the mold, tray bottom feet are demolded when the pop-up slide block moves, and tray side surfaces are demolded when the hydraulic slide block moves; and the lifters lift to take a tray out of a mold core after the injection molding process is finished, and the structure solves the problems that an existing novel tray injection molding mold is large in weight and high in cost.

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to a novel tray forming mold injected with a chemical foaming agent. Background technique [0002] Injection molding, also known as injection molding, is a molding method of injection and molding. The advantages of the injection molding method are fast production speed, high efficiency, automatic operation, various designs and colors, simple to complex shapes, large to small sizes, accurate product sizes, easy replacement of products, and complex shapes. Parts, injection molding is suitable for mass production and complex shape products and other molding processing fields. It is one of the most important processes in the manufacture of polymer parts. It accounts for more than 1 / 3 of all processes in processing plastic parts. The appearance and characteristics of injection molded parts are also greatly dependent on raw materials, mold design and processing variables. [0...
