Abstract

The invention discloses a non-balance injection shaping mould which includes, from left to right successively, a mould closing system, a fixed mould part, and a moving mould part. The mould closing system includes, from left to right successively, a moving clamp plate, a top plate arranged on the inner side of the moving clamp plate, a support mould plate, a moving mould pad plate being connected to the support mould plate, and a pushing needle. The moving mould part includes, from left to right successively, a first heat insulating plate and a moving mould plate. The fixed mould part includes, from left to right successively, a fixed mould plate, a third heat insulating plate and a fixed mould base plate. Hot and cold medium channels are formed in the interiors of the moving mould plate and the fixed mould plate; a moulding cavity is formed by the moving mould plate, the fixed mould plate and a second heat insulating plate and is used for moulding; a mould temperature control apparatus is arranged on exterior of the injection shaping mould. The injection shaping mould also comprises a sprue bushing being communicated with the moulding cavity. The injection shaping mould can achieve stable regulation and control on thermodynamic status of the moulding cavity, and can be used for conveniently, quickly and controllably preparing inhomogeneous ordered high-molecular-based gradient materials in different forms.

Description

technical field [0001] The invention relates to the field of forming molds, more specifically, to an unbalanced injection molding mold. Background technique [0002] Traditional material science attaches great importance to "uniformity" and "interface" to seek to improve material performance. The phases of materials are uniformly distributed macroscopically and are isotropic in performance. However, with the diversification of material requirements due to the development of science and technology, materials with a single property can no longer meet the requirements, and functionally graded materials have emerged as the times require. Functional graded material (Functional Graded Material, FGM) is to use two or more raw materials with different properties to control the shape and combination of microscopic elements (including composition, structure and voids) inside the material by using different composite technologies. A non-uniform composite material that exhibits a conti...
