In 2024, Donglai precision mould Co., Ltd. made the drawing planning requirements for Plastic mould design
1. product structure design: design a reasonable product structure according to the overall size, shape, wall thickness and other factors of plastic products to ensure the function and appearance quality of products.
2. mold structure design: design the corresponding mold structure according to the product structure, including mold opening mode, mold size, structure, material and other elements, to ensure the stability and life of the mold.
3. mold processing technology design: design the corresponding processing technology according to the mold structure, including mold manufacturing technology, processing technology, heat treatment technology, etc., to ensure the accuracy and life of the mold.
4. selection of plastic materials: select suitable plastic materials according to the use requirements of products, production costs and other factors to ensure product performance and cost control.
5. mold trial and debugging: conduct mold trial and debugging according to the designed mold structure and process parameters to ensure product quality and production efficiency.
A: Plastic mold processing design drawing
1. whether the parts of each mold on the plastic mold design drawing are appropriate, whether the marks are clear and whether they are missing
2. the part number, title, manufacturing quantity and internal manufacturing of the parts on the design part drawing of the two-color plastic mold are still outsourced, standard parts are still non-standard parts, the precision of parts’ cooperative disposal, the correction processing and allowance at the high-precision scale of plastic products processed by injection molding, and whether the materials, heat treatment, appearance treatment and appearance refinement engineering degree of the two-color plastic mold parts are symbols and clearly described.
3. the operation scale and cooperation scale of the primary parts of two-color plastic mold design parts, injection molding parts. The scale number should be correct, and the manufacturer should not convert it.
4. check the view orientation of all two-color plastic mold part drawings and general assembly drawings, whether the projection is correct, whether the drawing method conforms to the national drawing standard, and whether there is any missing scale.
5. drawing checking and processing function of two-color plastic mold
(is the layout, drawing method and scale mark of all parts conducive to the processing of two-color plastic mold)
6. recalculate the primary operation scale of two-color plastic mold auxiliary things
B. In principle, the professional correction shall be carried out according to the self correction project of the planner; However, we should focus on the layout principle, skill function and operation safety.
When tracing, first digest the graphics, describe according to the requirements of the national standard, and fill in all the scales and skill requirements. Self check and sign after tracing.
Plastic mould design
C. The traced base map shall be submitted to the planner for correction and signature. The customary practice is that the relevant skilled personnel of the East and West production unit shall check, countersign and check the production skills, and then send it to the sun.
D. . write and make skill cards
The skilled personnel of the East-West production unit shall compile the production skill card and prepare for the processing and production.
In the manufacturing process of mold parts, inspection should be strengthened, and the key points of inspection should be placed on the scale accuracy. After the completion of mold assembly, the inspector shall check according to the mold inspection table. The first thing is to check whether the functional status of the mold parts is outstanding. Only in this way can we slang the manufacturing quality of the mold.
