What are the requirements of gusset plate mold design and production

The requirements of gusset mold design and manufacture are:accurate size and smooth surface;Reasonable structure,high production efficiency and easy automation;Easy manufacture,high service life and low cost;The design meets the needs of the process and is economical and reasonable.

Rigidity,guidance,unloading mechanism,positioning method,gap size and other factors must be considered in die structure design and parameter selection.The vulnerable parts on the mold should be easy to replace.For plastic mold and die-casting mold,it is also necessary to consider the reasonable pouring system,the flow state of molten plastic or metal,and the position and direction of entering the cavity.In order to improve productivity and reduce runner pouring loss,multi cavity mold can be used,which can complete multiple identical or different products at the same time in one mold.High efficiency,high precision and long life moulds should be used in mass production.

Stamping die should adopt multi position progressive die,and carbide insert progressive die can be adopted to improve service life.In small batch production and trial production of new products,simple dies with simple structure,fast manufacturing and low cost should be used,such as combined dies,sheet dies,polyurethane rubber dies,low melting point alloy dies,zinc alloy dies,superplastic alloy dies,etc.The mould has begun to adopt computer aided design(CAD),that is,to optimize the design of the mould through a set of computer-centered systems.This is the development direction of mold design.

According to the structural characteristics,mold manufacturing is divided into flat blanking die and cavity die with space.Blanking dies use the size of punch and die to match accurately,and some even have no clearance.Other forging dies such as cold extrusion die,die casting die,powder metallurgy die,plastic die,rubber die,etc.belong to cavity die,which are used to form three-dimensional workpiece.The cavity mold has dimensional requirements in three directions of length,width and height,and its shape is complex and difficult to manufacture.Mold production is generally single piece and small batch production,and the manufacturing requirements are strict and accurate.Precision processing equipment and measuring devices are mostly used.

The plane blanking die can be formed by EDM,and then form grinding,coordinate grinding and other methods to further improve the accuracy.Form grinding can be carried out by optical projection curve grinding machine,or surface grinding machine with reduction and grinding wheel mechanism,or by special form grinding tools on precision surface grinding machine.Coordinate grinder can be used for precise positioning of mold to ensure precise aperture and hole spacing.You can also use computer numerical control(CNC)continuous trajectory coordinate grinder to grind punch and die with any curve shape.Cavity mold is mostly processed by profiling milling machine,EDM and ECM.The combination of profile milling and numerical control and the addition of three-way translational head device in EDM can improve the machining quality of the cavity.Adding gas filled electrolysis in electrochemical machining can improve production efficiency.
