Forming method of negative angular object

Abstract

A method for manufacturing an object with negative angle in order to present its 3D effect includes such steps as providing raw materials, splitting the object to be made into a main body and at least one convex decorative part, preparing their moulds, making said main body and decorative part, and assembling them together to obtain the target object.

Description

technical field [0001] The present invention relates to a molding method, in particular to a molding method of an object with a negative angle by using a negative angle design to highlight the object's three-dimensional vision. Background technique [0002] Generally, for rapid prototyping and manufacturing of objects, mold opening is used for direct molding, so as to achieve the effect of mass production and cost reduction; refer to figure 1 , the conventional object mold opening and forming method includes a material preparation step 11, a molding step 12 and a finished product step 13 in sequence; wherein, the material preparation step 11 is to prepare the raw materials (such as plastics, etc.) to be formed, and then prepare the materials to be formed. object 2 (such as figure 2 shown) to be molded into a mold (that is, the mold opening step 12), and the mold is filled with raw materials and processed into one piece, and finally formed as figure 2 Object 2 is shown (i...

Problems solved by technology

[0003] refer to figure 2 , but the conventional mold (not shown in the figure) molding is to directly open the required mold according to the shape required by the object 2, so as to facilitate the subsequent filling of raw materials for processing and molding; however, in order to facilitate the integral molding of the object 2, the mold is easy to Considering the removal of the mold, the pattern or pattern on the object 2 cannot form an inwardly inclined inclined surface (that is, a negative angle), otherwise it is easy to cause the phenomenon that the mold cannot be removed. Because of this, the object 2 to be formed cannot have a negative angle. Angle factors will cause the object 2 that is filled and molded to fail to highlight the stereoscopic vision

[0004] Furthermore, since the object 2 is integrally formed, it is technically difficult to present multiple colors on the object 2 to be molded, unless additional filling processing equipment (not shown in the figure) is added. , but this approach will also cause an increase in the cost of machinery, and then transfer the price to the sales cost of the object 2, which is not competitive in the industry
