Description

TECHNICAL FIELD

[0001] The utility model relates to mould technical field, concretely is a mould blank subassembly convenient to replace. BACKGROUND

[0002] Mold (mújù), industrial production is used for injection, blow molding, extrusion, die casting or forging pressure forming, smelting, stamping and other methods to get the desired products of various molds and tools. In short, the mold is a tool for making shaped objects. Such a tool is made up of various parts, and different molds are made up of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. It is known as the "mother of industry". Under the action of external force, the blank becomes a workpiece with a specific shape and size. It is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy part pressing, pressure casting, and forming processing of engineering plastics, rubber, ceramic and other products. Mold has a specific contour or internal cavity shape. The application of the contour shape with a cutting edge can make the blank separate according to the contour line shape (blanking). The application of the internal cavity shape can make the blank obtain the corresponding three-dimensional shape. The mold generally includes a movable mold and a fixed mold (or a punch and a die), which can be separated and combined. When separated, the workpiece is taken out, and when combined, the blank is injected into the mold cavity to form. Hardware molds are divided into: including stamping dies (such as blanking dies, bending dies, drawing dies, hole flanging dies, hole shrinking dies, undulating dies, bulging dies, shaping dies, etc.), forging dies (such as die forging dies, upsetting dies, etc.), extrusion dies, extrusion dies, die casting dies, forging dies, etc. The mold is a precision tool with complex shape, and it bears the expansion force of the blank. It has high requirements for structural strength, rigidity, surface hardness, surface roughness and machining accuracy. The development level of mold production is one of the important symbols of the level of mechanical manufacturing. An important component of the mold is the mold blank. The mold blank is the basic framework or structural core of the mold. In the design and manufacturing process of the mold, the mold blank plays a crucial role. The mold blank is the skeleton and cornerstone of the mold, which provides the basis for installation and positioning for other components of the mold. Whether in injection molding, die casting or stamping, the mold blank is an indispensable part. It is usually composed of several steel plates or castings. These steel plates or castings are precisely machined and assembled to form a frame that can accommodate other mold components. The composition of the mold blank varies depending on the type and specific requirements of the mold, but generally includes base plates, fixed mold plates, movable mold plates, guide columns and guide sleeves. These parts are precisely machined and assembled to form a solid and accurate whole. Advanced machining techniques and strict quality management are required during the manufacture of the mold blank to ensure that it meets the high standards of mold manufacturing. The mold blank also needs to be replaced after long-term use. The current mold blank replacement process is too complex, which affects the replacement efficiency. SUMMARY
