Plastic Injection Mould Saving Materials And Ease Of Processing And Heat Treatment
Plastic Injection Mould manufacturing can be divided into the following steps:
First, the analysis of plastic products.
Before the design of the Plastic Injection Mould, the designer should fully analyze the study of its plastic products are in line with the principle of Plastic Injection Moulding processing, product designers need to carefully consult, has reached a consensus. Which includes the geometry of the product, dimensional accuracy and appearance requirements, the necessary discussion, try to avoid unnecessary unnecessary Plastic Injection Mould manufacturing.
Second, the Plastic Injection Mould structure design.
A set of high-quality Plastic Injection Mould, not only need to have a good processing equipment and skilled Plastic Injection Mould manufacturing workers, another very important factor is to have a good Plastic Injection Mould design, especially for complex Plastic Injection Moulds, Plastic Injection Mould design quality accounted for 80% %the above. A good Plastic Injection Mould design is: to meet the requirements of the guests under the premise of low processing costs, processing is difficult, processing time is short.
To do this, not only to completely digest the requirements of the guests, but also on the Plastic Injection Moulding machine, Plastic Injection Mould structure, processing technology and Plastic Injection Mould factory's own processing capacity to understand. Therefore, to improve the level of Plastic Injection Mould design, should do the following:
1. understand each set of Plastic Injection Mould design in every detail, understand the use of each part of the Plastic Injection Mould.
2. In the design of more reference to the previous similar design, and understand it in the Plastic Injection Mould processing and production of the situation, learn from the experience and lessons.
3. Learn more about the work of the Plastic Injection Moulding machine to deepen the relationship between Plastic Injection Mould and Plastic Injection Moulding machine.
4. Under the factory to understand the process of processing products, to understand the characteristics of each processing and limitations.
5. To understand their own design of the Plastic Injection Mould test results and change the situation, learn lessons.
6. In the design of the past as far as possible the use of more successful Plastic Injection Mould structure.
7. Learn more about the impact of Plastic Injection Mould water on the product.
8. Study some special Plastic Injection Mould structure to understand the latest Plastic Injection Mould technology.
Third, determine the Plastic Injection Mould material and select the standard parts.
In the selection of Plastic Injection Mould materials, in addition to consider the accuracy and quality of the product, but also combined with the Plastic Injection Mould factory processing and heat treatment of the actual ability to give the right choice. In addition, in order to shorte
Fourth, parts processing and Plastic Injection Mould assembly.
Accuracy of the Plastic Injection Mould In addition to the design to give the best structure and reasonable tolerance with the parts processing and Plastic Injection Mould assembly is essential. Therefore, the choice of machining accuracy and processing methods in the Plastic Injection Mould manufacturing occupies an absolute dominant position.
Therefore, in order to reduce the Plastic Injection Mould manufacturing error, we should first improve the machining accuracy, with the use of CNC machine tools, this problem has been well controlled. In addition, in order to prevent Plastic Injection Mould wear and deformation caused by the error in the processing of high precision and large output of the Plastic Injection Mould, the cavity, the core and other key parts should be quenched. In the large Plastic Injection Mould, in order to save materials and easy processing and heat treatment, Plastic Injection Mould design should be used to fight the structure.
In order to solve the uneven shrinkage of the Plastic Injection Moulded parts and the error caused by the inconsistency between the actual shrinkage and the actual shrinkage, the manufacturing tolerances of the Plastic Injection Moulds are generally chosen as the manufacturing tolerances of the Plastic Injection Moulds in order to give the later forming process Large room for adjustment to solve the errors caused by the Plastic Injection Moulding process.
Five test mode.
A set of Plastic Injection Mould from the beginning of the design to complete the assembly, but to complete all of its manufacturing process 70% to 80%. For the error caused by the inconsistency between the predetermined shrinkage and the actual shrinkage, the smoothness of the stripping, the cooling effect, especially the size, position and shape of the gate, the influence of the shape and the appearance of the product must be verified by the test mode. Therefore, the test mode is to test the Plastic Injection Mould is qualified and choose the best Plastic Injection Moulding process an indispensable step.
