1. Material selection

Chemical resistance: Paint often contains corrosive components, the barrel material needs to have good chemical resistance to avoid reaction or degradation.

Mechanical strength: The material should have sufficient impact and compression resistance to prevent deformation or breakage during transportation or stacking.

Environmental protection: Priority is given to recyclable materials to reduce environmental impact.

2. Structural design

Tightness: The lid design should ensure a good seal, prevent paint leakage or volatilization, avoid contamination and safety risks.

Easy to open: The lid should be easy to open and close, while ensuring tightness and improving user experience.

Stability: The bottom design should ensure that the barrel body is stable and prevents tipping, especially for large capacity barrels.

3. Capacity and size

Capacity selection: According to the market demand design of different specifications, common capacity of 1 liter, 5 liters, 20 liters and so on.

Size optimization: The size design should consider transportation and storage efficiency to ensure a solid stack and save space.

4.Security

Non-slip design: The barrel body should be designed with non-slip texture, easy to grip and prevent slipping.

Fire performance: the paint is flammable, and the material should have certain fire performance to reduce the risk of fire.

5. Environmental protection and sustainability

Recyclable design: The barrel body should be easy to recycle and reduce the environmental burden.

Reduce material use: under the premise of ensuring strength, minimize the amount of material, reduce costs and environmental impact.

6. User experience

Portability: Designed handle or handle for easy handling, especially for large capacity drums.

Easy to clean: the inner wall should be smooth, easy to clean and reuse.

7. Cost control

Production costs: Optimize the design to reduce production costs while meeting the premise of functionality and safety.

Transportation costs: The design should be easy to transport and reduce logistics costs.

 

 

 

Optimize cooling waterway design

Increase the number of waterways: Add more cooling waterways in the mold to ensure even cooling.

Shorten the water distance: make the cooling water closer to the surface of the cavity, improve the cooling efficiency.

Balanced waterway layout: Ensure that the waterway is evenly distributed to avoid local overheating or overheating.

Modified cooling medium

Use efficient coolants: Choose coolants with better thermal conductivity, such as special cooling oils or water-based coolants.

Control the coolant temperature: keep the coolant temperature stable to avoid too high or too low affecting the cooling effect.

Increase coolant flow rate: Increase coolant flow rate to enhance cooling effect.

Optimize mold materials

Choose materials with high thermal conductivity: Use die steels with better thermal conductivity, such as beryllium copper alloy.

Surface treatment: Chrome plating or nitriding treatment on the mold surface to improve thermal conductivity and wear resistance.

Adjust injection molding process parameters

Reduce the melt temperature: appropriately reduce the plastic melt temperature to reduce the cooling time.

Extend the cooling time: Extend the cooling time appropriately to ensure that the plastic is fully cooled.

Optimize the holding pressure: adjust the holding pressure to reduce product shrinkage and deformation.

Regular mold maintenance

Clean up the waterway: regularly remove the scale and impurities in the waterway to keep the waterway smooth.

Check tightness: Make sure the cooling water is well sealed to prevent coolant leakage.

 

 

 

 

The inclined top mechanism is an important part for release in plastic moulds, especially in products with concave or inverted structure (such as paint buckets). In the paint bucket mold, the inclined top mechanism is used to release the reverse structure at the mouth or bottom of the barrel to ensure smooth release of the product without damage. The following are the main components and working principles of the inclined top mechanism:

1. The main components of the inclined top mechanism

Inclined ejector rod: The ejector rod that is installed at an Angle and is responsible for pushing the product to release the mould.

Diagonal bracket: A base for holding the diagonal bracket, usually mounted on a thimble plate.

Guide block: Ensure that the inclined ejector rod moves at a predetermined Angle to prevent deviation.

Reset spring: helps reset the inclined ejector rod when closing the mould.

Wear-resistant block: reduce the friction between the inclined rod and the die, and extend the service life.

2. How it works

When opening the mould: the thimble plate pushes the inclined ejector rod, and the inclined ejector rod moves along the inclined Angle to push the product out of the reverse buckle area.

When closing the mould: the reset spring makes the inclined ejector rod return to the initial position to ensure the normal closure of the mould.

3. Design essentials

Angle design: The tilt Angle of the inclined rod is usually between 5° and 15°, and the Angle is too large to increase friction, and the demoulding force is insufficient.

Material selection: High hardness and wear-resistant materials, such as SKD61, should be selected for inclined rod and wear-resistant block.

Lubrication: Regular lubrication is required between the tilting rod and the guide block to reduce wear.

Strength calculation: To ensure that the inclined rod can withstand the demoulding force to avoid deformation or fracture.
