Hardware knowledge: the definition of various molds

The forming die has a forming cavity to complete the forming and blanking process module called forming die.

Guide plate mold guidelessdie A mold guided by a guide plate is called a guide plate mold. Because the guide plate for punching complicated shape parts is troublesome and easy to be deformed by heat treatment, this kind of mold is only suitable for parts with simple shapes and small sizes.

Guide post (pillar) typedie uses a guide post and a guide sleeve to guide the die is called a guide post die. This type of die has reliable guidance, high parts precision, high die life, easy installation, and is suitable for mass production. However, mold processing and manufacturing are complicated and costly.

Low-melting alloy die diesmadebylow-mcltingpoingalloys The working part of die steel is made of low-melting alloy (mainly bismuth-tin alloy), which is called low-melting alloy die. This kind of mold has the characteristics of remelting and remanufacturing.

Compound die compound die uses one stroke of the press to complete more than two processes in the same position of the die, which is called compound die. This kind of mold can ensure high parts accuracy, flatness and productivity, but it is complicated to manufacture and high in cost.

Steel strip die steelstripdie The die made of hardened thin steel strip (skin) is called steel strip die (steel skin die). The die material for supporting the steel strip cutting edge can be wood, zinc-based alloy, Easy-to-process materials such as superplastic alloys. This kind of mold is easy to manufacture, saves mold materials, and the cutting edge can be replaced at any time. It is generally suitable for simple parts and small batch production.

The splint mold templatedie; steelplatedie connects two steel plates at one end together, the lower one is processed with a concave die edge, and the male die is connected to the other (the steel plate has better elasticity), the blank A simple mold placed between the two for blanking is called a clamping mold.

Simple mold planedie; simpledie molds that only complete one process in one stroke of the press are called simple molds (as shown in the picture). This type of mold has a simple structure, is easy to manufacture, and is suitable for small batch production.

In one stroke of the continuous die prlgressivedie press, the die that completes several pressing processes on different parts of the die at the same time is called continuous die (as shown in the figure). This type of die has high production efficiency and is easy to realize automation, but High positioning accuracy is required, manufacturing is troublesome, and the cost is high.

Mold life dielife The total number of parts that can be processed before the mold is scrapped is called the mold life.

The bottom dead center of the mold maximum (minimum) maximum(minimum)shutheightofdie press slider, the mold closing height adjustment up (down) reaches the maximum (minimum) mold closing height is called the mold minimum closing height.

Convex (concave) mold fillet radius punch(die)radius The fillet radius of the transition from the punch (concave mold) end to the side is called the convex (concave) mold fillet radius.

Guidelessdie without a guide device is called a guideless die. The mold structure is simple, easy to manufacture, low cost, but troublesome installation and adjustment, low punching parts, and low mold life.

Rubber die rubberdie The mold that uses rubber as a punch or a concave die in a die is called a rubber die.

The working part of the zinc-based alloy mold zincalloydie mold is made of zinc-based alloy (mainly Zn93%, Cu3%, Al4%). The mold made is called the zinc-based alloy mold. This mold has the characteristics of remelting and remaking .

Center of pressure centerofdie(load) The point of action of the resultant force of the punching force is called the center of pressure

Special mold dieforspecialpurpose The mold used specifically to complete a specific process is called a special mold. This kind of mold has strong specificity and high productivity, but it is more complicated to manufacture and install, which is suitable for mass production.

Automatic mold transferdie The mold in which the feeding, discharging and waste removal are completely automatically completed by machinery is called automatic mold.
