Dongguan Plastic mold factory friends, you know the number of plastic mold cavity and cavity layout how to determine it? The determination of the cavity is necessary to ensure the best production economy, technically and fully guarantee the quality of the product, that is, should ensure that the best technical and technical aspects of plastic. Today, the editor for the simple introduction of the number of plastic mold cavity and how to determine the cavity layout.
The number of cavity design basis:
(1) the weight of the product and the maximum injection volume of the injection machine.
(2) Projection area of the product and the clamping force of the injection machine.
(3) mold size and injection machine to install the effective area of the mold. (Ie, the distance between the injector rod)
(4) product accuracy. (The number of improved, the corresponding reduction in the accuracy of plastic parts, according to experience the value of each increase in a cavity, plastic parts to reduce the accuracy of 4% to 8%)
(5) side core pulling and its handling method.
(6) Production quantities of products. (Monthly or annual batch)
(7) Economic benefits. (The production value of each mold)
Number of cavities:
Essentials: it is necessary to ensure the best production economy, technically and fully guarantee the quality of the product, that is, should ensure that the best technical and technical aspects of plastic.
1. Plastic production of the bulk and delivery cycle: the plastic parts (radio back cover) is the mass production of products, delivery cycle is shorter, the use of multi-cavity mold can provide a unique superior conditions.
2. Quality control requirements: the plastic parts do not belong to the high-precision production requirements of the product, the accuracy is not high use of multi-cavity has a higher production efficiency.
3. Plastic variety and other aspects: The plastic used in plastic plastic materials, flow performance is good.
4. After the above analysis and my experience, summed up: the use of a cavity is the best form, with the best economy.
