There are many factors that affect the quality of Furniture Mould accessories, such as the type and quality of die casting machines, the rationality of the structure and technical requirements of die castings, the structure of furniture moulds and the technical level of operators. Under certain conditions, the cutting allowance can be kept less, which is beneficial to extend the life of fine furniture mould accessories with high quality. What are the factors that affect the quality of furniture mould fittings?

1. The rationality of accessory planning

Planners should first fully understand the user's application requirements, working conditions and die-casting force, and then select appropriate data according to the application requirements and working environment to understand the die-casting function of the data. In the planning of furniture mould fittings, special attention should be paid to the premise of satisfying the application requirements, and the die-casting structure should be as simple as possible. The wall thickness is appropriate and uniform, and the necessary mould slope is left. Otherwise, the casting will show defects such as pits, pores, shortening, Undervoltage, stretch marks, cracks, deformation, etc. The requirement for dimensional accuracy of castings should be reasonable, otherwise, it will bring unnecessary trouble to mould planning, mould processing, process condition formulation and handling, and will form many unqualified products.

2. Mould structure, machining accuracy and mould data selection

Die casting is closely related to product quality such as die-casting, die planning, processing, and die data selection. The structure of the mould is unreasonable. No matter what method is adopted in the process of furniture mould fittings, it is difficult to make the products qualified. In addition, the mould data, mould processing precision, surface roughness, processing traces, heat treatment cracks, nitride layer thickness and mould assembly of heat-resistant and wear-resistant furniture mould accessories will affect the product quality and mould life.

3. The reduction rate of accessory data

The shortening rate of casting data is usually selected in the form of a uniform percentage or percentage that must change the range. For the planning of high-precision die castings and moulds for furniture mould accessories, special attention should be paid to the selection of shortened data. If necessary, the mould can be tested first, the required data can be obtained from the test mould, and then the production quantity of large moulds to be planned and manufactured can be carried out.

To sum up, the formulation and implementation of the die-casting process for furniture mould accessories are related to the quality of the mould and die-casting equipment and the technical level of the operators. Under the condition of existing die-casting equipment in China, it is still difficult to complete stable, reliable and accurate control of the process parameters of fine furniture mould accessories. The completion of the fundamental control process is a process of merging and applying elements such as equipment, data and moulds.
