Open mould for butterfly valves as per customer’s sample /Drawing or technical datas
The below butterfly valve mould is popular in the KSA market , we open the mould as per customer’s request.
The mould opening process as below
1. Conduct a feasibility analysis on the product of the designed mold, Firstly, use design software to perform assembly analysis on the product drawings of each component, which is referred to as the set diagram in our work, to ensure the correctness of the product drawings before mold design. On the other hand, familiarize yourself with the importance of each component in the entire case to determine the key dimensions, which is very beneficial in mold design.
2. After product analysis, the work to be carried out is to analyze the product and use what kind of mold structure to use, arrange the product process, determine the punching content of each process, and use design software to unfold the product. When unfolding the product, it is generally carried out from the subsequent engineering. For example, one product requires five processes, and after stamping is completed, the product is unfolded from the product drawing to the fourth, third, second, and first engineering. After unfolding a graphic, a copy is made before proceeding with the expansion work of the previous engineering. That is to say, the product development work of the fifth engineering is completed, and then detailed work is carried out. Note that this step is important and requires special attention. If this step is completed well, when drawing the mold, In the diagram, a lot of time will be saved. After determining the stamping content for each project, Including in the forming mold, the inner and outer lines of the product material thickness are retained to determine the size of the convex and concave molds.
3. Material preparation: Prepare materials according to the product development diagram, determine the template size in the drawing, including various fixed plates, discharge plates, convex and concave molds, inserts, etc. Pay attention to directly preparing materials in the product development diagram, which is very beneficial for drawing the mold diagram. I have seen many mold designers manually calculate the product development diagram to prepare materials, which is too inefficient. Directly drawing the template specifications and dimensions on the drawing in the form of assembly drawings can complete the material preparation on one hand, and on the other hand, it saves a lot of work in the work of mold accessories, because in the work of drawing each component, only positioning, pins, guide pillars need to be added to the material preparation drawing. Screw holes are sufficient
4. material preparation is completed, the mold drawing can be fully entered. In the material preparation drawing, another copy can be made to draw various components, such as adding screw holes, guide pillar holes, positioning holes, and other hole positions. In the punching die, various holes need to be wire cut through wire holes, and in the forming die, the forming gap between the upper and lower molds must not be forgotten. Therefore, after these works are completed, the mold drawing of a product is almost 80% complete. In addition, in the process of drawing the mold drawing, attention should be paid to: each process, such as marking by fitters, wire cutting, etc., has a complete production layer for different processing steps, which is very beneficial for wire cutting and drawing management, such as color differentiation. Dimensioning is also a very important task, and it is also the most troublesome one because it is a waste of time.
5. After the completion of the above drawings, It is necessary to proofread the mold drawings, assemble all accessories, make different layers for each different mold plate, and analyze the mold assembly using the same benchmark, such as guide pillar holes, and produce each process
