What problems should we pay attention to in the structural design of the drip die?

The drip die is a mold used for plastic injection molding. Its structural design has an important impact on the performance and production efficiency of the mold. The following are some problems that need attention in the design of the drip die structure:

1. Adapt to the requirements of the product: the structural design of the drip die should be designed according to the specific product requirements, such as size, shape, weight, etc. At the same time, it is also necessary to consider the dropper form required by the product, such as straight-through type, diverting type, etc., as well as the size and Angle of the dropper.

2. Plastic fluidity: The structural design of the drip die should consider the fluidity of the plastic. First of all, it is necessary to ensure that the plastic can flow smoothly to every corner of the mold during the injection process, so as to avoid defects such as short shots and bubbles. Secondly, it is necessary to avoid excessive shear force during the flow of plastics to prevent excessive heat from being generated, affecting product quality and mold life.

3. Cooling system: The structural design of the drip die should reasonably set the cooling system to ensure that the die can be cooled quickly and evenly. The cooling system should include a cooling water channel that facilitates the flow of plastic and can dissipate heat quickly, as well as a cooling water pipe that can cool to the surface of the mold. Reasonable cooling system can speed up the production cycle of the mold and improve production efficiency.

4. Mold material selection: The structural design of the drip mold should choose the appropriate mold material according to the nature of the product, the production cycle and other factors. In general, the drip die needs to have wear resistance, corrosion resistance, high hardness and high heat resistance. Commonly used mold materials are high quality alloy steel, stainless steel and so on.

5. Exhaust system: The structural design of the drip die should pay attention to the setting of a reasonable exhaust system to exclude the gas generated during the plastic injection process. The exhaust system should be provided with appropriate air holes in the plastic flow channel to prevent bubbles from getting trapped in the mold, thus affecting the quality of the product.

6. Precision control: The structural design of the drip die should pay attention to precision control, especially in the process of plastic injection, it is necessary to maintain the accurate size and Angle of the drip. In order to maintain the accuracy of the parts, the structural design of the mold should be reasonable layout of the parts, and reduce the deformation and displacement of the parts as much as possible.

7. Maintenance and maintenance: The structural design of the drip die should be convenient for maintenance and maintenance. After a long time of use, the mold will appear wear, corrosion and other problems, which need to be repaired and replaced in time. Therefore, the structural design of the drip die should take into account the convenience of mold maintenance, such as the design of an easy-to-disassemble structure and standardized parts.

8. Production cost: The structural design of the drip die should also consider the control of production cost. Reasonable structural design can reduce material and processing costs, improve the life of the mold and production efficiency.

To sum up, the structural design of the drip die needs to consider many factors, such as product requirements, plastic flow, cooling system, mold material selection, exhaust system, precision control, maintenance and maintenance, and production costs. Only reasonable structural design can ensure the quality and production efficiency of the mold.
