Description

Mould embryo flip structure Technical Field The utility model relates to the technical field of dies, in particular to a die blank overturning structure. Background The mould is used for producing various moulds and tools of the needed products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods in industry. In short, a mold is a tool used to make a molded article, which is made up of various parts, with different molds being made up of different parts. The processing of the appearance of the article is realized mainly by changing the physical state of the formed material. The term "industrial master" refers to a tool that, under the action of an external force, makes a blank into a part of a specific shape and size. The method is widely used for blanking, die forging, cold heading, extrusion, powder metallurgy part pressing, pressure casting and the molding processing of compression molding or injection molding of engineering plastics, rubber, ceramics and other products. The die has a specific contour or cavity shape, and the blank can be separated (blanked) according to the contour shape by using the contour shape with the cutting edge. The blank can obtain a corresponding three-dimensional shape by using the shape of the inner cavity. The mold generally comprises a movable mold and a fixed mold (or a male mold and a female mold), which can be separated and combined. And taking out the workpiece when the workpiece is separated, and injecting the blank into the die cavity for forming when the workpiece is closed. The hardware mould comprises a stamping mould (such as a blanking mould, a bending mould, a drawing mould, a hole flanging mould, a shrinkage mould, a fluctuation mould, an bulging mould, a shaping mould and the like), a forging mould (such as a die forging mould, an upsetting mould and the like), an extrusion mould, a die casting mould, a forging mould and the like, wherein the mould is a precise tool, has a complex shape and bears the expansion force of a blank, has higher requirements on structural strength, rigidity, surface hardness, surface roughness and machining precision, and the development level of mould production is one of important marks of the mechanical manufacturing level. The mold base is the bone and foundation stone of the mold, which provides the basis for the installation and positioning of the other components of the mold. The blank is an integral part of the injection mold, the die casting mold or the stamping mold. It is typically composed of several steel plates or castings that are precisely machined and assembled to form a frame that can house other mold assemblies. The primary role of the mold blank has several aspects. First, it provides a stable structure to ensure accuracy and long-term stability of the mold. Secondly, the mould embryo provides accurate positioning and guidance for each part of the assembly of the mould, and ensures the consistency and accuracy of the product. In addition, the preform also carries a cooling and heating system for the mold, which is critical to ensure quality of the injection molded part and control of the molding process. The composition of the mold blank varies depending on the type of mold and the specific requirements, but generally includes portions such as a base plate, a stationary platen, a movable platen, a guide post, and a guide sleeve. These parts are precision machined and assembled to form a solid and precise whole. Advanced machining technology and strict quality management are required to be applied in the mould blank manufacturing process so as to ensure that the mould blank can meet the high-standard mould manufacturing requirement, and the product on the surface of the current mould blank is not easy to fall off, so that the production efficiency is affected. Disclosure of utility model The utility model aims to provide a die blank overturning structure, which solves the problem that the product on the surface of the current die blank is not easy to fall off, thereby influencing the production efficiency.
