Methods to Improve the Quality and Accuracy of Pipe Fitting Molds

As the name suggests, pipe fitting molds are molds used to produce various types of pipe fittings, and they have high requirements for accuracy, so we need to pay special attention to them. So how can we improve the accuracy of pipe fitting molds when producing them? Let's take a brief look below.

1. The design of pipe fitting molds is an extremely important step in improving mold quality:

① The selected mold materials not only meet the customer's requirements for product quality, but also need to consider the cost of the materials and their strength within the set period. Of course, the selection of materials should also be based on factors such as the type of mold, working mode, processing speed, and main failure modes.

② When designing the structure of pipe fitting molds, it is important to have a compact structure and easy operation, while also ensuring that the mold parts have sufficient strength and stiffness; When the mold structure allows, the corners of each surface of the mold parts should be designed as rounded transitions as much as possible to avoid stress concentration;

③ In design, it is necessary to reduce the scope of disassembly and assembly when repairing a certain component, especially when replacing vulnerable parts, and minimize their disassembly and assembly scope as much as possible.

2. The manufacturing process of pipe fitting molds is also an important part of ensuring mold quality. The processing methods and precision used in the manufacturing process of pipe fitting molds can affect the service life of the molds. The accuracy of each component directly affects the overall assembly of the mold. In addition to the influence of the equipment's own accuracy, it is necessary to improve the machining methods of the parts and enhance the technical level of the fitter in the mold grinding process to improve the machining accuracy of the mold parts. 

3. Strengthening the surface of the main forming components of the pipe fitting mold to improve the wear resistance of the mold parts and thus enhance the quality of the mold. For surface strengthening, different strengthening methods should be selected according to the molds used for different purposes.

4. The correct use and maintenance of pipe fitting molds is a major factor in improving mold quality. The installation and debugging of pipe fitting molds should be appropriate. In the case of hot runner, the power wiring should be correct, the cooling water circuit should meet the design requirements, and the parameters of injection molding machines, die-casting machines, and compression machines in production should comply with the design requirements.

5. The design of the component should be reasonable, and the best structural scheme should be selected as much as possible. The designer of the component should consider the technical requirements of the component and ensure that its structure conforms to the processability and feasibility of mold manufacturing.
