Injection Mold Design Steps
The design of the injection mold must follow the following steps:
(1) Plastic analysis
1. Specify the design requirements of plastic parts
Carefully read the part drawing of plastic parts, and consider the feasibility and economy of injection molding process from various aspects such as the plastic variety, plastic shape, dimensional accuracy, surface roughness, etc. If necessary, discuss with the product designer about the possibility of material type and structure modification of plastic parts.
2. Specify the production batch of plastic parts
In small batch production, the mold shall be as simple as possible to reduce the cost; In mass production, under the premise of ensuring the quality of plastic parts, try to use the first mock examination with multiple cavities or high-speed automatic production to shorten the production cycle and improve productivity. Therefore, strict requirements are put forward for the ejection mechanism of the mold, the automatic ejection mechanism of plastic parts and runner aggregates.
3. Calculate the volume and mass of plastic parts
The purpose of calculating the volume and quality of plastic parts is to select injection molding machines, improve equipment utilization and determine the number of mold cavities.
(2) Selection of injection molding machine
Roughly determine the structure of the mold according to the volume or weight of the plastic parts, preliminarily determine the model of the injection molding machine, understand the technical parameters of the injection molding machine used related to the design of the mold, such as: the diameter of the positioning ring of the injection molding machine, the hole diameter and spherical radius of the front nozzle, the maximum injection volume of the injection molding machine, the mold locking force, the injection pressure, the area size of the fixed template and the movable template and the position of the installation screw hole, the spacing of the pull rod of the injection molding machine, the closing thickness, the mold opening stroke, Ejection stroke, etc.
(3) Calculation related to die design
1. Calculation of working dimensions of concave and convex die parts;
2. Determination of cavity wall thickness and base plate thickness;
3. Determination of mold heating and cooling system.
(4) Mold structure design
1. Selection of molding position and parting surface of plastic parts;
2. Determination of mold cavity number, cavity arrangement, runner layout and gate position setting;
3. Structural design of die working parts;
4. Design of side parting and core pulling mechanism;
5. Ejection mechanism design;
6. Type selection of draw bar;
7. Exhaust mode design.
(5) Determine the overall dimension of the mold, and purchase the mold base
The mold base has been standardized gradually. The mold base is selected according to the mold base atlas provided by the manufacturer, and the complete structure diagram of the mold is preliminarily drawn on the basis of the above mold parts design.
(6) Verification of injection molding machine parameters
1. Check the maximum injection quantity;
2. Check the injection pressure;
3. Check the clamping force;
4. Check the relevant dimensions of the installation part of the mold and injection molding machine, including the closing height, mold opening stroke, mold base installation dimensions, etc.
(7) Drawing of die structure general assembly drawing and part working drawing
The drawing of the general drawing of the mold must conform to the national standard of mechanical drawing. In principle, there is no difference between the drawing method and the general drawing method of mechanical drawing, but in order to more clearly express the shape of the molded products in the mold and the setting of the gate position, the fixed mold can be removed from the top view of the general drawing of the mold, and only the top view of the moving mold can be drawn.
The general assembly drawing of the mold should include necessary dimensions, such as mold closing dimension, overall dimension, feature dimension (the dimension of the locating ring matched with the injection molding machine), assembly dimension, limit dimension (the starting and ending points of moving parts) and technical conditions, and the preparation of parts list.
Generally, the processing cycle of the main working parts is long and the processing accuracy is high, so they should be carefully drawn first, and the remaining parts should be standard parts as far as possible.
(8) Overall review of production and manufacturing
Mold designers shall generally participate in the whole process of processing, assembly, mold testing and production.

FAQ:
1.Q: I have an idea for a new product, but I don't know if it can be manufactured. Can you help?
A:Yes! We are always happy to work with potential customers to evaluate the technical feasibility of your idea o r design and we can advise on materials, tooling and likely set-up costs.
2.Q:What are the advantages to have my parts manufactured locally?
A:WinWin Mold can offer quick reaction times to any changes in specification, batch size or material. We can ship small or large quantities anywhere in North America, Europe overnight to accommodate unforeseen changes in demand.
3.Q: My components have already been developed on CAD. Can you use the drawings?
A: Yes! DWG, DXF, IGES, Solid works and STP, X_T files can all be used to generate quotes, models and mould tools - this can save time and money in producing
your parts.
4.Q: Can I test my idea/component before committing to mould tool manufacture?
A:Yes, we can use CAD drawings to make Prototype models for design and functional evaluations or market test.
5.Q:What type of plastic is best for my design/component?
A: Materials selection depends on the application of your design and the environment in which it will function. W e will be happy to discuss the alternatives and suggest the best material.
6.Q:What type of mould tool do I need?
A:Mould tools can be either single cavity (one part at a time) or multi-cavity (2,4, 8 or 16 parts at a time). Single cavity tools are generally used for small quantities, up to 10,000 parts per year whereas multi-cavity tools are for larger quantities. We can look at your projected annual requirements and recommend the
best tooling option for you.
7.Q:Ok, I've decided to go ahead with my project. How long will it take to get my parts?
A: It can take 3 to 6 weeks to have the mould tool manufactured depending on the part's complexity, size and the number of impressions/ cavities (single or multiple). After we receive your final approval on the tool preliminary design, you can expect delivery of T1 parts within 3-6 weeks. And during mold building process, mold build Weekly Update will be provided to you every week for your better understanding of the manufacturing progress in our work shop.
