When we started planning and manufacturing plastic molds, we carefully considered several options and weighed the advantages and disadvantages of each option. One of them is desirable, and we should also treat T-shaped molds carefully. For reasons of constant awareness, even through production and use practices, there must be local areas where reasonable planning can be considered at the time.

Plastic mold planning and production basis

The planning and production of plastic molds are mainly based on product drawings and templates provided by customers. Planners should carefully analyze and digest products and templates. In addition, during the planning process, all projects need to be checked.

1. The accuracy of the relevant scale.

1) For clinker products with high appearance requirements and low dimensional accuracy requirements, such as toys, the detailed dimensions should be consistent except for the recipe.

2) Patrol products with strict standards.

2. Is the mold lift angle reasonable

3. Product wall thickness and uniformity.

4. Plastic varieties. (Selection of plastic varieties, steel used to steal molds, and determination of shrinkage)

5. Surface requirements.

6. Product color. Generally speaking, color does not directly affect mold planning. When the wall thickness and appearance of a product are large, color spots are prone to occur; In addition, the darker the color, the more obvious the shortcomings of the product.

7. Whether there is post treatment after the product is formed. When there is only one mold cavity on the surface of an electroplated product, it should be considered to set up an auxiliary flow path to connect the product, and the product can be separated after the electroplating process is completed.

Product batch size and product batch size are important bases for mold planning. Customers should provide a scale that recognizes the number, size, material selection, and service life of mold cavities.

9. Specification of injection molding machine.

10. Other customer requirements. The planner should carefully consider and check to satisfy the requirements.

The general process of planning and manufacturing plastic molds

Analyze and digest products and templates.

2. It is necessary to understand whether the customer has any requirements for the specifications of the injection machine and acknowledge the size of the mold.

3. Recognition and sequencing of the number of cavities.

4. Recognition of parting surface.

5. If there are rows and oblique structures, it is necessary to understand them first.

6. Pouring system planning

7. Recognition of inlay structures.

8. Push and reset system planning.

9. Cooling and heating system planning.

10. Guide equipment. Positioning equipment.

11. Recognize the embryo and select the standard.

12. Selection of mold steel.

13. Complete structural drawings, mold drawings, and materials.

14. Print, verify, and submit to the mold planning team leader and supervisor.

Plastic mold planning, prototype production, and repair products

Plastic mold planning and manufacturing: When selecting molding materials and equipment, mold planning is carried out under expected process conditions, but people often do not have much understanding. Therefore, after mold processing is completed, trial production experiments should be conducted to recognize the quality of the molded product. Always notice and demonstrate troubleshooting.

There are many types of undesirable phenomena in plastic parts, but the reasons are also complex, including mold and process conditions, which are often intertwined. Before repairing a part, it is necessary to conduct a detailed analysis and study based on the actual situation of the defective phenomenon occurring in the part, find out the reasons for the defect of the part, and then propose a repair method. Due to the variability of molding conditions, if changing the molding conditions still does not solve the problem, it is generally considered to repair the mold. Mold repair should be more prudent and should not be hasty. The reason is that if the mold conditions are changed, greater transformation or restoration cannot be carried out.

Plastic mold planning, production, archiving, summary data

After planning and manufacturing experiments for plastic molds, when not in use for the time being, remove mold release slag, dust, oil stains, etc., apply butter or other anti rust oil or anti rust agent, and store them in a closed storage area. The planned molds are successfully processed by the mold until they pass the inspection. During the process, technical information such as base drawings, mold planning instructions, inspection records, and inspection records may seem cumbersome, It is very helpful for repairing molds and planning new molds in the future.
