Molds and tools for industrial production. Generally speaking, it is a kind of tool for mold making. This tool is made up of various parts. Under the action of external force, the blank becomes a workpiece with specific shape and size. Different molds are made up of different parts. It can process the shape by changing the physical state of the material. It is known as the "mother of the industry". Any commodity is made of mould. It can be said that there is no mould production, which is widely used in various industries.
For example, our common household appliances such as TV sets, mobile phones, telephone casings and other communication equipment products are produced by injecting plastic heating software into molds and cooling them. Rice cookers are also made of metal plates and pressed into such shapes by molds. The mold has a specific shape or cavity shape. The mold is a precision tool with complex shape, high requirements for the expansion force of bear blank, structural strength, rigidity, surface hardness, surface roughness and machining accuracy. The development of mold production is an important sign of the level of mechanical manufacturing.
The cost of physical mold manufacturing is generally very high. A set of large mold is tens of thousands or even millions, especially in the medical industry, millions of mold is very common. If the die has unreasonable structure or other problems in the process of installation, the loss will be great. Therefore, it is generally necessary to confirm the appearance, structure and function of the hand board first, and then open the mold for mass production after confirming that there is no problem.
The manual version can also be called the sample version, sample version, sample version. In some places, it is called "the first version", that is, the first version of the product. In Japan, it is also called "the manual version". The English translation is "rapid prototype". The first step to verify the feasibility of the product is to find the most direct and effective way to find out the defects, defects and shortcomings of the design product, in order to improve the targeted way of defects, until the defects can not be found from the personal hands of the model board. Usually, it is necessary to carry out small batch trial production, and then find out the defects to improve.
Usually, newly developed or designed products need to be made into hand models. The designed product can't be perfect or even can't be used. Once there are defects in direct production, all of them will be scrapped, which greatly wastes manpower, material resources and time. However, the general situation of handboards is that the sample size is small, the production cycle is short, the loss of manpower and material resources is small, so we can quickly find out the shortcomings of product design, and then improve it to provide sufficient basis for product design and mass production.
