The Basic Process of Injection Molding Development

Injection molding development for the current plastic processing market, the impact is very large, and investigate the reason, mainly because the current plastic production, many product structure is more unified, so once there is a new type of product, then it will bring a great impact on the market, and injection molding development is also representing the emergence of a new type of product.

In the process of injection molding development, the whole process contains a lot of content. Development is not said to come, need to go through a very detailed market research, and then according to the corresponding design, step by step to improve the results obtained, for the basic process of injection mold development, mainly includes:

First, product analysis and modification, determine the mold structure.

1, product analysis: mold opening direction, parting line and parting surface, shape size, thickness, drawing Angle, back hook and corresponding core pulling mode, glue point and feeding mode, mold hole number, etc.

2. Transfer engineering drawing: Use 3D software to draw.

3. Shrinkage diagram: Mirror the previous engineering drawing once and enlarge a multiple of the shrinkage rate.

Second, product ranking: How to arrange in the mold

Factors to consider: the length and width of the mold, the number of die holes, the position of the glue, the interval.

Three, mold ordering. According to the size of the product, production batch, number of die holes, core pulling mechanism, etc.

Four, mold ordering. According to the size of the mold and the core pulling mechanism (side), the way and position of feeding glue, whether the front mold has core pulling (opening mold action, oil cylinder), product material, ejection method and so on.

5. Assemble the mold kernel into the mold embryo

6. Mold kernel and mold embryo installation and positioning design

Seven, parting line, pillow position, insert design

8, if the customer's product has a backward hook to design the core pulling mechanism such as row or inclined top design

9. Design pouring system (direct gate, side gate, diving gate, horn gate, point gate, fan gate, lap gate, etc.)

10, if it is a fine water mouth mold, then design the opener and the plug screw

11. Exhaust system design (exhaust slot location and product overflow value)

12, ejector system design (thimble, inclined top, cylinder, ejector block, push plate, gas cap, etc.)

13, cooling system design (water style such as straight through, stepped, diaphragm, spiral, etc.)

14. Auxiliary parts (spring, garbage nail, stay head, center toist, lock template, button machine, side lock, balance block, limit block, hanging hole, prying die pit, etc.)

15, check and modify, view supplement and position adjustment

16, 2D to 3D parting or do full 3D

17. Disassembled parts drawing (3D+2D)

18, drawing review, change the drawing.

19. Print and file drawings after they are qualified

20. The drawings are sent to the mold manufacturing workshop for processing
