The layout of plastic mold has an important impact on product quality, production efficiency and mold life. The following are some factors that may affect the layout of plastic molds:

1. product design requirements: the shape, size and structure of the product will directly affect the layout of the mold. The structure of the mold must match the requirements of the product to ensure the accuracy and quality of the product.

2. production process requirements: different plastic product production processes require different mold layout. For example, injection molding, blow molding and extrusion molding have different mold layout requirements.

3. production efficiency: the mold layout should make the production process more efficient and smooth. Reasonable mold layout can reduce the production process and time, and improve production efficiency.

4. mold maintenance and replacement: the mold layout should take into account the maintenance and replacement of the mold. Vulnerable parts and parts that often need maintenance shall be easy to disassemble and replace to reduce downtime and maintenance costs.

5. die life: the die life shall be considered in the die layout. Reasonable layout can reduce the wear and fatigue of the die and prolong the service life of the die.

6. equipment and factory conditions: the mold layout also needs to consider the equipment and factory conditions. For example, the size and weight of the mold should meet the requirements of the production equipment, and the placement position of the mold should conform to the spatial layout of the factory.

7. cost consideration: the cost factor should also be taken into account in the mold layout. Reasonable layout can reduce the cost of mold manufacturing and maintenance, and improve production efficiency.

Plastic mold is also called plastic mold, also known as injection mold. It plays an important role in the manufacturing industry in modern industrial production, and various products produced by plastic mold in various types of mold steel are widely used in various industries. The mold design and manufacturing is very complex, so the layout of plastic mold must be analyzed before design

1. plastic mold cavity planning. According to the layout characteristics of the plastic parts, the requirements of scale accuracy, the size of the batch, the difficulty of mold making, the cost of plastic mold, etc., the number of cut-off cavity and its placement method.

As for the plastic mold, the precision of plastic parts is grade 3 and Grade 3A, the weight is 5g, the hardened pouring system is selected, and the number of cavities is 4-6; The plastic parts are of normal accuracy (level 4-5), the molding materials are some crystalline materials, and the number of cavities can be 16-20; The weight of plastic parts is 12-16g, and the number of cavities is 8-12; For plastic parts with a weight of 50-100g, the number of cavities is 4-8. For amorphous plastic parts, the number of cavities is 24-48, 16-32 and 6-10. When the plastic parts are added continuously, the multi cavity mold is rarely used. For plastic parts with 7-9 grade accuracy, the number of multiple cavities is 50% higher than that of plastic parts with 4-5 grade accuracy.

2. determine the parting surface of the plastic mold. The orientation of parting surface shall be conducive to mold processing, exhaust, demoulding and molding operations, and the appearance quality of plastic parts.

3. determine the pouring system (the shape, orientation and size of the main sprue, runner and gate) and the exhaust system (the method of exhaust, the orientation and size of the exhaust slot).

4. select the ejection method (ejector rod, pipe jacking, push plate, combined ejection), and decide the side concave disposal method and core pulling method.

5. determine the cooling and heating methods, the shape and orientation of the heating and cooling groove, and the equipment position of the heating element.

6. according to the plastic mold material, strength accounting and experience data, determine the thickness and shape dimensions of mold parts, shape layout and all connections, positioning and orientation of guide parts.

7. determine the layout method of primary formed parts and layout parts.

8. consider the strength of each part of the mold and calculate the operation scale of the formed parts.
