In the process of actual processing and manufacturing of Chair Mould, there are more technological achievements transformed here, and it is also an important development field of the high-tech industry. Many people think that in the process of actual development, a steady stream of power can be injected into society. How should the chair mould be designed in the process of selection or design?
1. mould opening direction
In the process of processing the chair mould, each product must determine the mould opening direction before starting to set up. This way, the irregular situation of all products can be reduced as much as possible and the influence of the products on the appearance can also be eliminated. After the mould opening direction is determined, the structures of the products in various places can be ensured to be consistent in design as much as possible, and the structures in the buckles or bulges of the products can be ensured. The consistency with the mould opening direction must be guaranteed to avoid the reduction of splicing seams, and the service life of the mould must be effectively prolonged. After the mould opening direction is determined, an appropriate parting line can be selected to avoid the phenomenon of reverse buckling in the mould opening direction.
2. Demoulding slope
During the actual processing and production of the chair mould, the inclination of the demoulding can effectively prevent the product from having the inclination of a roughened and smooth surface, usually more than 0.5 degrees, and the fine surface is more than 1 degree, and the surface of the whole rough leather grain is usually more than 1.5 degrees. Appropriate assistance can effectively prevent various top injuries of the product, such as white top or deformation of the top. In addition, if the slope of the whole structural product can be well done during the design process, then they will basically be larger than the slope of the inner surface. In this way, the mould will not shift during injection moulding, the whole product can obtain uniform thickness, and the material strength of the opening position of the product can be ensured.
3. Product wall thickness
During the overall processing and design of the chair mould, all kinds of plastics must ensure the thickness of the product wall uniformly. Generally speaking, their thickness is controlled between 0.5 mm and 4 mm. When the wall thickness of the whole product exceeds 4 mm, the cooling time will be relatively long. The whole product may have a shrinkage problem. Moreover, the original structure of the product must be taken into account. The thickness of the whole product will not cause surface shrinkage, and they will not cause air holes or welding marks.
When designing the chair mould, the design of the reinforcing ribs must be reasonable, the rigidity of the whole product must be effectively enhanced, and the deformation must be rapidly reduced in a short time, because the thickness of the reinforcing ribs must be ensured to be between 0.5 and 0.7, otherwise the surface may shrink, and the unit area of the reinforcing ribs must be greater than 1.5 degrees to avoid the top injury.
The Daily Necessities Mould has six systems, and the guide system is set up to ensure that the moving mould and the fixed mould can be accurately centred when closing the mould. The guide components must be set up in the daily necessities mould. Four sets of guide posts and guide sleeves are usually used to form guide parts in injection moulds for daily necessities. Sometimes, the movable mould and the fixed mould need to be respectively provided with mutually matched inner and outer conical surfaces to assist in positioning.
The guide pillar mainly plays a guiding role in the daily necessities mould to ensure that the moulding surfaces of the core and the cavity do not touch each other under any circumstances, and the guide pillar cannot be used as a force bearing member or a positioning member. How to deal with the damage of the guide pillar during the use of the injection mould for daily necessities?
In several cases, when injecting, the moving and fixed dies will produce huge lateral deflection force. When the wall thickness of the plastic parts is not uniform, the flow rate through the thick wall is high, resulting in greater pressure. The sides of the plastic parts are asymmetrical, such as the daily necessities mould with stepped parting surface, and the opposite two sides are subjected to unequal back pressures.
In order to produce a set of high-quality injection daily necessities mould, injection mould factories need to understand every detail in the design, manufacture and moulding of each set of moulds and understand the use of each part in daily necessities mould. Knowing the important role of the guide pillar in the daily necessities mould and the harm that the damage of the guide pillar brings to the entire daily necessities mould will better pay attention to such problems in subsequent use, not only an excellent plastic products be better manufactured, but also the service life of the injection daily necessities mould is greatly prolonged.
Before the production of the product, carefully selecting and designing a reasonable Household Product Mould is the basic method to reduce the cost. Different household product mould design structures have different requirements on product materials, and naturally, there are good and bad. Excellent household product mould has a high yield, less waste and lower natural production cost.
The quality and quantity of raw materials required for the same product are different with different production and processing technologies. According to the characteristic requirements of the products, on the premise of meeting the quality requirements, the production cost can be effectively reduced by using the method of improving the processing technology.
In order to improve the service performance of household product mould, many manufacturers will properly process their moulds. Household product mould processing refers to the processing of forming and blank making tools, in addition to shearing moulds and die-cutting moulds. However, in many cases, the finished moulds will also show processing defects, resulting in the decline of mould performance.
With the rapid development of Table Mould(FURNITUREMOULD) manufacturing technology, mould has become an important part of today's manufacturing technology. At present, table mould manufacturing technology is also developing in the direction of accelerating information drive, improving manufacturing flexibility, agile manufacturing and system integration. In order to produce the table mould, in view of the current domestic mould manufacturing technology level and quality, the following table mould manufacturing conditions are introduced for your reference.
1. Cleaning workshop
In a dirty environment, it is impossible to produce high-quality table mould. The mould production area should be kept highly clean and the maintenance and management level is higher than that of the product production area. Therefore, dust removal and cleaning should be done in the mould manufacturing area before the mould manufacturing starts.
2. Pure and dry air
The supply of clean and dry air is another factor in making high-quality table mould. There will be a large number of pinholes and pits on the surface of the adhesive layer, requiring a large number of manual repairs. Therefore, the quality of the table mould will be greatly affected. The air compressor should be installed in a good environment and equipped with an effective air dryer and oil-water separator.
3. Environmental conditions
Temperature: During the whole manufacturing process of positive and negative mould, i.e. 21-28 degrees Celsius, the same ambient temperature should be maintained at all times.
Humidity: Humidity has great influence on curing of rubber coating and resin. The ideal humidity range is 40-60. If the relative humidity in the mould manufacturing process exceeds 65, the construction shall be restarted under appropriate production conditions.
4. Selection of raw and auxiliary materials
Selecting high-quality raw and auxiliary materials is an important condition for producing high-quality table moulds. The cost of raw and auxiliary materials used to make moulds only accounts for a small part of the total cost. It is impossible to economize on the use of product resins or non-stock materials and inferior materials.
5. Establish a reasonable moulding schedule
Reasonable arrangement of moulding time is one of the important factors to make a good table mould. Whether the traditional paving method or the new low shrinkage system is adopted, the time required depends on the chemical characteristics of these raw and auxiliary materials. Trying to take a shortcut or speed up the processing will have a negative impact on the quality of the mould.
